Looking back on China’s road to outer space, people can easily find it has not been very smooth. In the past years, Chinese people have made hard and determined efforts to realize the dream their ancestors had for thousands of years.
After China’s first satellite into the Earth’s orbit in 1970 came four flights of unmanned Shenzhou missions(飛行) from 1999 to 2002. The country carried out its first one-piloted space flight in October, 2003, making China the third country in the world to have independent human spaceflight ability after the Soviet Union and the United States. Then came another breakthrough on October 12, 2005, when Shenzhou 6, China’s second human spaceflight, was launched, with a crew of two astronauts. What’s more, the landmark spacewalk done by Zhai Zhigang, one of the three boarding Shenzhou 7, launched on Sept. 25, 2008, leads the country further in its space exploration.
Meanwhile, China’s moon exploration project, started in 2004, has also been progressing satisfactorily. Fifty years after the Soviet Union launched Sputnik, the world’s first man-made satellite, China’s first circumlunar(繞月的)satellite Chang’e 1 took off on Oct.24, 2007, which became another milestone(里程碑) in China’s space achievements after the above-mentioned manned flights. Chang’e 1 was expected to fulfill four scientific goals, one of which was to probe(勘探)mineral elements on the moon, especially those not existent on Earth. It’s said that the lunar regolith(月壤) is abundant in helium-3, a clean fuel that may support the Earth’s energy demands for more than a century. Nearly 3 years later, Oct. 1, 2010 witnessed the blasting off of Chang’e 2, China’s 2nd unmanned lunar probe, marking another step forward in moon exploration. This time the aim is to test the key techniques of Chang’e 3 and Chang’e 4, as a preparation for a soft lunar landing in the future.
With great expectations, people all over the world are looking forward to China’s greater space achievements.

Do you know that women’s brains are smaller than men’s? The average women’s brain weighs 10% less than men’s. Since researches have shown that the bigger the brain, the cleverer the animal, men must be more intelligent than women. Right? Wrong. Men and women always score similarly on intelligence tests, despite the difference in brain size. Why? After years of study, researchers have concluded that it’s what’s inside that matters, not just the size of the brain. The brain consists of “grey matter” and “white matter”. While men have more of the latter, the amount of “thinking” brain is almost exactly the same in both sexes.
It has been suggested that smaller brain appears to work faster, perhaps because the two sides of the brain are better connected in women. This means that little girls tend to learn to speak earlier, and that women can understand sorts of information from different sources at the same time. When it comes to talking to the boss on the phone, cooking dinner and keeping an eye on the baby all at the same time, it’s women who come out on top every time.
There are other important differences between two sexes. As white matter is the key to spatial(空間的) tasks, men know better where things are in relation to other things. “A great footballer always knows where he is in relation to the other players, and he knows where to go,” says one researcher. That may explain one of life’s great mysteries—why men refuse to ask for directions … and women often need to!
The differences begin when fetuses(胎兒) are about nine weeks old, which can be seen in the action of children as young as one. A boy would try to climb a barrier (障礙物) before him or push it down while a girl would attract help from others. These brain differences also explain the fact that more men take up jobs that require good spatial skills, while more women speech skills. It may all go back to our ancestors, among whom women needed speech skills to take care of their babies and men needed spatial skills to hunt, according to one research. www. .com
If all this disappoints you, it shouldn’t. “The brain changes throughout our lives according to what we do with it.” says a biologist.

Bissel is a small village of the West Sahara. It lies next to a l.5-square-kilometer oasis(綠洲), from where three days and nights are generally required to go out of the desert. However, before Ken Levin discovered it in 1926, none of the Bissel villagers had ever walked out of the desert. Reportedly, they were not unwilling to leave this barren land. Many had previously tried but failed, always somehow finding themselves back at the oasis after several days of trying to walk out.
When interviewed by Ken Levin, an expert at the British Royal College of Sciences, the villagers explained that no matter which direction they walked it always brought them back to the village.Why couldn’t the Bissel villagers walk out of the desert? Levin was very puzzled. He had, by himself, managed to walk north from the village and reach the nearest town in three and a half days. He decided to carry out an experiment to solve the mystery. He and a Bissel villager called Argutel, would walk out of the desert together. They prepared enough water for a half-a-month journey and two camels. But this time Ken Levin didn't bring his compass. Levin would follow Argutel.
Ten days later, they had walked for about 500 miles but were still in the desert. On the 11th morning, an oasis came into their view. They were back at Bissel. Levin now understood why the Bissel people couldn’t escape the desert. They had no knowledge of the North Star, which had for centuries provided sailors and other travelers with a point of direction. In the desert, if a person goes forward relying only on their senses, they will not be able to travel in a straight line. Rather they will travel in a very large circle and eventually track back to where they began. Levin explained to Argutel the function of the North Star and said, “As long as you rest in the daytime and walk towards the brightest star at night, you would be able to walk out of the desert.” Argutel did as he was told. Three days later, he came to the edge of the desert.
Now in the West Sahara, Bissel has become a bright pearl, where tens of thousands of tourists come every year. Argutel’s bronze statue stands in the center of the town. On its base are the words: __________________________.
【小題1】Ken Levin asked Argutel to walk to the north in order to ________.
A.prove that people could walk out of the desert see |
B.how far away Bissel was to the edge of the desert |
C.tell people not to walk in circles |
D.show Argutel was a great person |
A.knew Argutel before he came to the village |
B.came to Bissel to do experiments on behalf of his college |
C.became the first man to walk out of the desert from Bissel Village |
D.taught Bissel villagers knowledge of the North Star when he first arrived |
A.Ken Levin didn’t walk south because it would take more days |
B.the use of a compass was necessary to walk out of the desert |
C.tourism in Bissel has been greatly developed and improved |
D.Argutel became the leader of Bissel after his return |
A.A new life starts from the fixed direction. |
B.Where there is a will , there is a way . |

Unknown to most Facebook users, the social network actually offers a lot of privacy controls and security features which can help you lock your account, so you can speak freely. If it’s used properly, you’ll never have to worry about whether you will have to “friend” your boss or your mom. You can friend anyone you want while staying comfortable in the knowledge that not everyone gets to see everything you post.
The problem with carrying out these privacy options is that they’re just too confusing for most non-tech clever people to handle. And often, most people don’t want to bother to take the time to learn. To simplify the process, we’re offering one easy step you can take today to help make your Facebook experience safer, more secure, and more private.
Just make “Friend Lists”. Yes, it will take some time, especially if you’re connected to a couple of hundred friends already. But this step, while not the quickest, is fairly simple. And it will be one of the most useful things you can do on Facebook.
Friend lists, as the name suggests, are lists for classifying your friends into various groups. The nice thing about this feature is that once you set these lists up, you won’t have to do it again. We suggest that you put your work colleagues and professional acquaintances into a friend list named “Work”, personal friends you’re not very close with into a list called “Acquaintances”, and people you’re related to into a list called “Family”. Those three main categories will separate out the groups of “friends” who you may want to hide some information from.
To create a friend list, click on “Friends” at the top of the Facebook homepage. In the left-hand column, click “Friends” again under the “Lists” section. Now you’ll see a button at the top that says “Create New List”. Click it. In the pop-up that appears, you can name your list and pick members. If you’ve ever shared an application with your friends, the process of doing this will be very familiar.
When you’ve finished making lists, you’ll be able to use them when selecting who can see what (or who can’t!) when configuring (配置) the security settings described below.
【小題1】What function isn’t understood by most people on Facebook?
A.Surfing the Internet. |
B.Setting safety protection. |
C.Sharing personal information. |
D.Making foreign friends. |
A.Its process of privacy-setting is too complex. |
B.It displays everything people post. |
C.It lacks privacy controls and security features. |
D.Its post is designed for technical people. |
A.We can avoid our bosses adding us as friends. |
B.We can share applications with friends. |
C.We can separate acquaintances from family. |
D.We can hide different information from different friends. |

How long you live has a lot to do with your environment and lifestyle, but exceptional(特別的)long life may have even more to do with your genes. For the first time, researchers have discovered a genetic recipe(基因譜)that accurately predicts who may live to 100 and beyond.
Analysis shows that 90% of the participants who lived to 100 had at least one of the signature genetic clusters(標(biāo)志基因組). Dr. Thomas Perls at the Boston University School of Medicine said, “We realize this is a complex genetic puzzle. There is a long way for us to go to understand how the integration(融合)of these genes—not just with themselves but with environmental factors—is playing a role in this long life puzzle.”
Perls has studied many factors that contribute to long life, and he is the first to acknowledge that living longer isn’t likely to be simply a matter of genes. His previous work has shown, for example, that among most elderly people who live into their 70s and 80s, about 70% can owe their long life to environmental factors such as not smoking; eating a healthy, low-fat, low-calorie diet; and remaining socially engaged and mentally active throughout life.
It seems clear that those who live extremely long are benefiting from a special DNA. In fact, Perls believes that the older a person gets, the more likely it is that his or her genes are contributing to those extended years.
【小題1】Which of the following is TRUE according to Paragraph 2?
A.Most long-living people have special long-life-related genes. |
B.Ninety percent of the participants lived to 100 years of age. |
C.All the long-living people have only one signature genetic cluster. |
D.Scientists know how the integration of the genes helps people live long. |
A.most people living extremely long benefit from not smoking |
B.living longer just depends on certain genetic recipes |
C.environmental factors play an important role in long-living |
D.being mentally active has nothing to do with living an old age |
A.Remaining socially engaged helps a person to live long. |
B.A genetic recipe can accurately predict who may live to 100 and beyond. |
C.Perls is the first to think living longer is just a matter of genes. |
D.The older he gets, the more likely the genes contribute to his extended years. |
A.Genes May Predict Who Lives to 100 | B.Environment And Genes |
C.Genes, the Secret of Long Living | D.Lifestyle And Genes |

Below is a selection from a popular science book.
If blood is red, why are veins (靜脈) blue?
Actually, veins are not blue at all. They are more of a clear, yellowish color. Although blood looks red when it’s outside the body, when it’s sitting in a vein near the surface of the skin, it’s more of a dark reddish purple color. At the right depth, these blood-filled veins reflect less red light than the surrounding skin, making them look blue by comparison.
Which works harder, your heart or your brain?
That kind of depends on whether you’re busy thinking or busy exercising. Your heart works up to three times harder during exercise, and shifts enough blood over a lifetime to fill a supertanker. But, in the long run, your brain probably tips it, because even when you’re sitting still your brain is using twice as much energy as your heart, and it takes four to five times as much blood to feed it.
Why do teeth fall out, and why don’t they grow back in grown-ups?
Baby (or “milk”) teeth do not last long; they fall out to make bigger room for bigger, stronger adult teeth later on. Adult teeth fall out when they become damaged, decayed and infected by bacteria. Once this second set of teeth has grown in, you’re done. When they’re gone, they are gone. This is because nature figures you’re set for life, and what controls regrowth of your teeth switches off.
Do old people shrink as they age?
Yes and no. Many people do get shorter as they age. But, when they do, it isn’t because they’re shrinking all over. They simply lose height as their spine (脊柱) becomes shorter and more curved due to disuse and the effect of gravity (重力). Many (but not all) men and women do lose height as they get older. Men lose an average of 3-4 cm in height as they age, while women may lose 5 cm or more. If you live to be 200 years old, would you keep shrinking till you were, like 60 cm tall, like a little boy again? No, because old people don’t really shrink! It is not that they are growing backwards—their legs, arms and backbones getting shorter. When they do get shorter, it’s because the spine has shortened a little. Or, more often, become more bent and curved.
Why does spinning make you dizzy (眩暈的)?
Because your brain gets confused between what you’re seeing and what you’re feeling. The brain senses that you’re spinning using special gravity-and-motion-sensing organs in your inner ear, which work together with your eyes to keep your vision balance stable. But when you suddenly stop spinning the system goes out of control, and your brain thinks you’re moving while you’re not!
Where do feelings and emotions come from?
Mostly from an ancient part of the brain called the limbic system. All mammals (哺乳動物)have this brain area — from mice to dogs, cats, and humans. So all mammals feel basic emotions like fear, pain and pleasure. But since human feelings also involve other, newer bits of the brain, we feel more complex emotions than any other animal on the planet.
If exercise wears you out, how can it be good for you?
Because our bodies adapt to everything we do to them. And as far as your body is concerned, it’s “use it, or lose it”! It’s not that exercise makes you healthy; it’s more that a lack of exercise leaves your body weak and easily affected by disease.
【小題1】What is the color of blood in a vein near the surface of the skin?
A.Blue | B.Light yellow |
C.Red | D.Dark reddish purple |
A.Because their spine is in active use. |
B.Because they are more easily affected by gravity. |
C.Because they keep growing backwards. |
D.Because their spine becomes more bent. |
A.In the long run, our brain probably works harder than our heart |
B.When our brain senses the spinning, we will feel dizzy. |
C.The brains of the other mammals are as complex as those of humans. |
D.Our feelings and emotions come from the most developed area in our brain. |

New research shows that overweight or even mildly obese people have a lower risk of early death than people considered to be normal weight.
Researchers examined the results of 97 studies. Most of the studies were less than 10 years old. They included almost three million adults from around the world, including the United States, Canada, China, Taiwan, Brazil, India and Mexico.
The researchers at the National Center for Health Statistics found that people who are considered overweight or slightly obese were five to six percent less likely to die from all causes than people of normal weight. People with higher obesity ratings, however, had almost a 30 percent greater risk of death compared to normal-weight individuals.
Katherine Flegal was the lead author of the study. She says she was not surprised that overweight people would not have a higher risk of death.
“Because we’d actually already read a lot of this literature and realized it was likely that mortality rates (死亡率) for overweight would be at least not higher than normal weight. I guess I was a little bit surprised that it was definitely lower. And I was also surprised that the lower rates of obesity also didn’t seem to differ from normal weight.”
But she says the difference in death rates appears to be small between normal-weight people and those who are overweight or mildly obese.
The study has raised new questions about “body mass index,”(體重指數(shù)) or BMI. This is a measurement of body fat as a ratio(比率) of height to weight. In recent years, many public health experts have promoted body mass index as a way to predict the risk of health problems. Bu t a person's BMI can be misleading in some cases.
Steven Heymsfield ,the executive director of the Pennington Biomedical Research Center, says people can be physically fit and in good health, but might weigh more because they are more muscular.
Still, Dr. Heymsfield says people should not think gaining extra weight is OK just because of the new findings. He says being at a healthy weight lowers the risk for heart disease and diabetes(糖尿。.
【小題1】According to the new findings, the researchers found that __________ .
A.People with high obesity have a lower risk of early death than people with low obesity |
B.People with overweight have a greater risk of early death than people of normal weight. |
C.People with mild obesity are less likely to die than people of normal weight. |
D.People with obesity live much longer than people of normal weight. |
A.works like novels and poems |
B.books and articles on a particular subject |
C.printed material |
D.magazines and newspapers |
A.BMI is commonly used to measure body fat as a ratio of height to weight. |
B.Not all people with a little higher BMI are fat . |
C.Many public health experts encourage more people to use BMI as a way to predict the risk of health problem |
D.Because of the ne w findings, people should think about gaining extra weight. |

Sports shoes that work out whether their owner has done enough exercise to warrant time in front of the television have been devised in the UK.
The shoes — named Square Eyes — contain an electronic pressure sensor and a tiny computer chip to record how many steps the wearer has taken in a day. A wireless transmitter passes the information to a receiver connected to a television, and this decides how much evening viewing time the wearer deserves, based on the day’s efforts.
The design was inspired by a desire to fight against the rapidly ballooning waistlines among British teenagers, says Gillian Swan, who developed Square Eyes as a final year design project at Brunel University in London, UK. “We looked at current issues and childhood overweight really stood out,” she says. “And I wanted to tackle that with my design.”
Once a child has used up their daily allowance gained through exercise, the television automatically switches off. And further time in front of the TV can only be earned through more steps.
Swan calculated how exercise should translate to television time using the recommended daily amounts of both. Health experts suggest that a child take 12,000 steps each day and watch no more than two hours of television. So, every 100 steps recorded by the Square Eyes shoes equals precisely one minute of TV time.
Existing pedometers (計步器) normally clip onto a belt or slip into a pocket and keep count of steps by measuring sudden movement. Swan says these can be easily tricked into recording steps through shaking. But her shoe has been built to be harder for lazy teenagers to cheat. “It is possible, but it would be a lot of effort,” she says. “That was one of my main design considerations.”
【小題1】According to Swan, the purpose of her design project is to ________.
A.keep a record of the steps of the wearer |
B.deal with overweight among teenagers |
C.enable children to resist the temptation of TV |
D.prevent children from being tricked by TV programs |
A.They regulate a child’s evening TV viewing time. |
B.They determine a child’s daily pocket money. |
C.They have raised the hot issue of overweight. |
D.They contain information of the receiver. |
A.The exact number of steps to be taken. |
B.The precise number of hours spent on TV. |
C.The proper amount of daily exercise and TV time. |
D.The way of changing steps into TV watching time. |
A.makes it difficult for lazy teenagers to cheat |
B.counts the wearer’s steps through shaking |
C.records the sudden movement of the wearer |
D.sends teenagers’ health data to the receiver |
A.Smart Shoes Decide on Television Time |
B.Smart Shoes Guarantee More Exercise |
C.Smart Shoes Measure Time of Exercise |

The State Council declared Wednesday it would restart China's nuclear power program, ending the hiatus(中斷)in nuclear construction since Japan's Fukushima nuclear disaster last year.
China has been the most courageous country in building nuclear power, with the largest number of plants currently under construction. Nuclear power is facing a tough time in developed countries. The Japanese public is demanding the closure of all the country's nuclear power plants. China is at the forefront of nuclear power development. But it has been forced into this position.
Rapid economic development coupled with improvements in people's life both demand more electricity. It is impossible to exploit fossil resources forever as the supply of coal, oil and natural gas is limited. China has no choice but to develop nuclear power.
China must be the safest user of nuclear power. It should become a leading country in developing nuclear power technologies and increasing the world's knowledge of nuclear power.
It needs to do at least two things. First, it needs to promote safety in nuclear power plants, based on the technologies of the West. The former Soviet Union, the US and Japan all had severe nuclear accidents, proving there are risks. China should try to remove these risks.
Second, China should establish effective communication mechanisms(機制)between the government, power plants and the public. It's wrong to think the government can control every aspect of nuclear power plant construction.
The opposition to nuclear power program in developed countries has prevented them from building new plants, but they already have many. These governments are reluctant to close these plants despite strong opposition, because they cannot find better substitutes.
Nuclear power only occupies 1.8 percent of China's current electricity grid(輸電網(wǎng)), much lower than the proportion in many developed countries. China's nuclear power plan should introduce the advantages of the technologies of other countries and also be creative in providing security. Its space technology is not the most advanced, but its launch safety measures have proven to be among the best.
China's high-profile high-speed railway development has drawn a lot of controversy, as will the active attitude towards developing nuclear power. But China cannot just copy what the developed countries have done. The development of nuclear power must be unique to China and it must be a ground-breaking success. But now, the real test lies ahead.
【小題1】In the third paragraph the writer focuses on ______.
A.the reason why China is to develop nuclear power |
B.the difficulty China has in developing nuclear power |
C.the measures China will take to develop nuclear power |
D.the benefits China will have by developing nuclear power |
A.Supportive. | B.Opposed. | C.Indifferent. | D.Objective. |
A.copy exactly what the developed countries have done |
B.depend entirely on domestic scientists and technologies |
C.a(chǎn)void people’s involvement in nuclear power plant construction |
D.do everything in its power to guarantee safety in nuclear power plants |
A.It will be unique but can hardly pass too many tests. |
B.It will be full of controversy but carried out firmly. |
C.It will be on a smooth way to a ground-breaking success. |
D.It will receive much opposition from developed countries. |
