Can dogs and cats get along well in the same home? People who are thinking about getting a dog as a friend for their cat are worried that they will fight. A recent research has found that if the cat is taken back home before the dog, and if they are introduced when still young (less than 6 months for cats, a year for dogs), it is highly probable that the two pets will get along swimmingly. In two-thirds of the homes cats and dogs have a good relationship.
However, it wasn’t all sweetness and light. There was a reported coldness between the cat and dog in 25% of the homes, while aggression(侵略，好斗) and fighting were found in 10% of the homes. One reason for this is probably that some of their body languages are just different. For example, when a cat turns its head away it means aggression, while a dog doing the same means submission(順從).
In homes with cats and dogs living peacefully, researchers found a surprising behavior. They are learning how to talk each other’s language. It is a surprise that cats can learn how to talk “Dog”, and dogs can learn how to talk “Cat”.
What’s interesting is that both cats and dogs have appeared to become smarter. They can learn to read each other’s body languages, suggesting that the two may have more in common than was expected. Once familiar with each other’s body language, cats and dogs can play together, and enjoy sleeping together on the sofa.
The importance of this research on cats and dogs may go beyond pets — to people who don’t get along well, including neighbors, colleagues at work, and even countries. If cats and dogs can learn to get along, surely people have a good chance.

The first robot rover to land on the Moon in nearly 40 years, China's Jade Rabbit, has begun sending back photos, with shots of its lunar lander(登月飛行器). Jade Rabbit rolled down a ramp lowered by the lander and on to the volcanic plain known as Sinus Iridum at 04：35 Beijing time on Saturday (20：35 GMT)．It moved to a spot a few metres away, its historic short journey recorded by the lander. On Sunday evening the two machines began photographing each other. A Chinese flag is clearly visible on the Jade Rabbit as it stands deployed on the Moon's surface.

Ma Xingrui, chief mander of China's lunar programme, declared the mission (任務(wù))a “plete success”. The first soft landing on the Moon since 1976 is the latest step in China's ambitious space programme, says BBC science reporter Paul Rincon.
The lander will operate there for a year, while the rover is expected to work for some three months. The Chang'e­3 mission landed some 12 days after being launched atop a Chinese­developed Long March 3B rocket from Xichang in the country's south. The official Xinhua news service reported that the lander began its descent(下降)on Saturday just after 13：00 GMT, touching down in Sinus Iridum (the Bay of Rainbows) 11 minutes later. “I was lucky enough to see a prototype rover(原型月球車) in Shanghai a few years ago ­ it's a wonderful technological achievement to have landed，” Prof Andrew Coates, from UCL's Mullard Space Science Laboratory, told BBC News.
Chang'e­3 is the third unmanned rover mission to touch down on the lunar surface, and the first to go there in more than 40 years. The last was an 840kg (1,900lb) Soviet vehicle known as Lunokhod­2, which was kept warm by polonium(釙)­210. But the six­wheeled Chinese vehicle carries a more sophisticated payload(復(fù)雜的有效負(fù)荷), including ground­penetrating radar which will gather measurements of the lunar soil and crust.
【小題1】What does the text mainly talk about?

A．China's space and aeronautics industry develops quickly.  
B．The importance of China's space and aeronautics industry. 
C．China's Jade Rabbit Moon rover sends back first photos. 
D．Chang'e­3 is the third unmanned rover mission to touch down on the lunar surface. 
【小題2】After ________ years' hard and scientific work, the first soft landing on the Moon has made such great progress.
A．nearly 40 B．37 
C．64 D．more than 40 
【小題3】The purpose that the Chinese moon rover has visited the moon is to ________.
A．do some research about the moon 
B．be the first settler on the moon 
C．to plant the Chinese flag onto the moon 
D．send a lovely jade rabbit onto the moon 
【小題4】From the text, we know that the lander began its descent on Saturday just after ________ Beijing time.

Want to travel as cheaply as possible while enjoying the great scenery as much as you like?
Backpacking is the way. As the most popular traveling choice among young western people, backpacking allows you to travel at your own free will. Carrying a tent, sleeping bag and clothes, backpackers also need to pack an attitude that will help them deal with many mental and physical challenges.
It is a thrill to put our ability to test and challenge ourselves with sorts of difficulties we might come across. So, backpacking is something young people can hardly deny.
Young people in Europe often travel around by train. Now, with plane tickets dropping in price, more are traveling to distant countries, such as Australia and China. And some just travel within their own countries.
But no matter where a backpacker travels, planning in advance is important if he or she wants to enjoy the trip.
Clothing
In summer, light, waterproof clothes are best. Backpackers must remember to travel lightly and not pack too many clothes.
Medicine
There are many medicines, especially for summer, such as those for sunstroke, snake bites and mosquitoes. Others are useful in every season, such as those for common colds, poisoning and diarrhea.
Cards
Three types of cards are of great value for backpacks: student Identity Card, personal ID and a credit card.
A student ID card can be helpful for saving money. It often gets train tickets and entrance tickets for cheaper prices in many Western countries.
Personal ID card can, not only get you out of trouble with local police, but also prove useful in all sorts of other situations.
Carrying a credit card can be a safe way of carrying money, as cash can easily get lost, stolen or wet.

Using too much water or throwing rubbish into our rivers are clear ways that humans can put our water supply in danger, but we also affect our water supply in less obvious ways. You may wonder how paving(鋪砌) a road can lead to less usable fresh water. A major part of the water we use every day is groundwater. Groundwater does not come from lakes or rivers. It comes from underground. The more roads and parking lots we pave, the less water can flow into the ground to become groundwater.
Human activity is not responsible for all water shortages(短缺). Drier climates are of course more likely to have droughts(干旱) than areas with more rainfall, but in any case, good management can help to make sure there is enough water to meet our basic needs.
Thinking about the way we use water every day can make a big difference, too. In the United States, a family of four can use 1.5tons of water a day! This shows how much we depend on water to live, but there's a lot we can do to lower the number.
You can take steps to save water in your home. To start with, use the same glass for your drinking water all day. Wash it only once a day. Run your dishwasher only when it is full. Help your parents fix any leaks (泄露、漏洞)in your home. You can even help to keep our water supply clean by recycling batteries instead of throwing them away.
【小題1】Which of the following is most likely to lead to less groundwater?

A．Using river water. B．Throwing batteries away.
C．paving parking lots. D．Throwing rubbish into lakes.
【小題2】The meaning of the underlined word mans          .
A．water on the ground B．water from a well(井)
C．water from the deep earth D．water from lakes or rivers
【小題3】What can be inferred from the text?
A．All water shortages are because of human behavior.
B．It takes a lot of efforts to meet our water needs.
C．There is much we can do to reduce family size.
D．The average family in America makes proper use of water.
【小題4】The last paragraph is intended to            .
A．show us how to fix leaks at home
B．tell us how to run a dishwasher
C．prove what drinking glass is best for us
D．suggest what we do to save water at home
【小題5】The text is mainly about _____________.
A．why paving roads reduces our water.
B．how much we depend on water to live.
C．why droughts occur more in dry climates.
D．how human activity affects our water supply.

Many of our favorite travel destinations are in danger of being changed badly by increased temperatures and rising seas. The following are some of the places that may be in danger and some that are already experiencing the effects of global warming.
The Everglades, Florida: Perhaps no region of the country is as unprotected to climate change as Florida. Even a slight increase in temperature and water level could devastate popular destinations like the Everglades, Miami Beach and the Keys.
Australia’s Great Barrier Reef: One of the most impressive natural habitats in the world, the Great Barrier Reef could be killed by increased water temperatures and the resulting coral bleaching (漂白法). Australia is particularly easily damaged by global warming because of its large number of fragile (脆弱的) ecosystems, uncertain water sources and a large group of people gathering on the coast.
Dalian, China: Fast-growing China, shown here during a heat wave last year, is opening about one coal factory every day this year. Along with the U.S., China is one of the world's leading contributors to the greenhouse gases , which can lead to the increase in the Earth's temperature.
Venice, Italy: No stranger to flooding, Venice has invested $4.5 billion in a floodgate system that is due to open in 2012. But the frequent changing ocean levels have made people question the floodgates' ability to hold out the rising waters.
London, England: Designed to protect London from storms and extremely high tides, the Thames Barrier was opened in 1984. Some analysts fear that rising oceans will create conditions beyond the capabilities the barrier was designed to meet.
【小題1】The word “devastate” in paragraph 2 means “_____________”.

A．protectB．destroyC．swallowD．enlarge
【小題2】What can endanger Great Barrier Reef directly?
A．Fragile ecosystem
B．Uncertain water sources.

Our body clock，or natural body rhythm，influences our energy and alertness．Paying attention to it can help us choose the suitable time of day when we best perform specific tasks．
The reality，however，is that most of us organize their time around work demands，school deadlines，commuting or social events．Doing whatever your body feels like doing is a luxury in today's fast-paced modem society．
But that doesn't mean it isn't worth trying．Obeying our body clock has significant health benefits．Disrupting our natural body rhythm，on the other hand，has been linked to problems such as depression，obesity，or headache，says Steve Key，a biology professor．
When the body clock can synchronize（使……同步）the rhythms of its natural processes，it “gives us an advantage in daily life”，says Key．
According to him，when it comes to cognitive（認(rèn)知的）work，most adults perform best in the late morning．As our body temperature starts to rise just before awakening in the morning and continues to increase until midday，our memory，alertness and concentration gradually improve．
However，he adds，our ability to concentrate typically starts to decrease soon thereafter．Most of us are more easily distracted（分心）between noon and 4 pm．
Alertness also tends to fall after eating a meal and sleepiness tends to peak around 2 pm，making that a good time for a nap．
Surprisingly, tiredness may increase our creative powers．For most adults，problems that require open ended thinking are often best dealt with in the evening when they are tired， according to a study in the journal Thinking & Reasoning．
When choosing a time of day to exercise，paying attention to your body clock can improve results．Physical performance is usually best from about 3 to 6 pm，says Michael Smolensky，a professor of biomedical engineering．
Of course, not everyone's body clock is the same，making it even harder to synchronize natural rhythms with daily plans．
【小題1】If we know our natural body rhythm well, we can         ．

A．find out the suitable time to do specific tasks
B．organize our time around work demands
C．do whatever our body feels like doing
D．be sure to be healthy
【小題2】Which of the following is NOT true?
A．Our alertness is influenced by our natural body rhythm
B．Doing whatever your body feels like is very difficult in our modem society．
C．Obeying our body clock is good for our health．
D．Disrupting our natural body rhythm can lead to obesity．
【小題3】According to Steve Key，which of the following is NOT true?
A．When our body clock synchronizes the rhythms of its natural processes，we can do better．
B．When it comes to cognitive（認(rèn)知的）work，most people perform best in the late morning．
C．As body temperature rises before awakening in the morning，our concentration gradually improves．
D．We concentrate better in the late morning than between noon and 4 pm．
【小題4】Inspiration（靈感）to solve a difficult problem will most probably come to us     ．
A．when we get up in the morning
B．when we are tired in the evening
C．when we are full of energy in the late morning
D．when we are asleep at night
【小題5】Which of the following can be the suitable title for the passage?
A．What is natural body rhythm?
B．Natural body rhythm is good for us．
C．Something about natural body rhythm．
D．The latest research about natural body rhythm．

The color red often means danger --- and by paying attention, accidents can be prevented. At railroad crossings, flashing red fights warn cars to stay back. A red light at a traffic crossing tells cars to stop, so they don't run into other cars.
In the future, the color red also may help prevent danger at construction sites. Thanks to new work by engineers, bridge supports --- or other kinds of materials --- could one day contain a color-changing material. It will turn red before a structure collapses(倒塌) or falls apart.
The secret behind the color-changing material is a particular type of molecule(分子). Molecules come in all shapes and sizes, and make up everything you can see, touch or feel. How a molecule behaves depends on what kinds of atoms(原子) it contains, and how they're held together.
To get a rough picture of one way atoms are held together in a molecule, imagine you and your friends standing in a large circle, holding hands. Each person represents one atom, your clasped hands represent the bond, and the entire circle represents a molecule.
The molecule being used to turn the material red is called mechanophore(機(jī)械響應(yīng)性聚合物). When one chemical bond in the mechanophore molecule breaks, the rest of the molecule turns red.
There is a way to get rid of~ the red color: light. When a bright light is shone on the mechanophore, the broken bond is fixed and the red color disappears. This "self-healing" may be a problem for engineers who want to use the color-changer in big construction projects that will be outside, in the sunlight. And if bright light keeps the red color from appearing, then the mechanophore's warning system will be useless.
Scientists still have a lot of work to do before the color-changing molecules can be used outside the lab. If mechanophore can be used in the real world, they are suggested to be employed in a new kind of paint.
【小題1】The first paragraph mainly tells us __________.

A．the color red is widely used in our life 
B．how to prevent car accidents 
C．the color is an important signal of warning 
D．how to use color red 
【小題2】The color red will be used at construction sites to _________.
A．tell different materials used in the building 
B．warn people that the building is dangerous 
C．make the building more beautiful  
D．tell people the building is under construction 
【小題3】The example given in the fourth paragraph is to show _________.
A．the way atoms are held together in a molecule 
B．how a molecule behaves in an object 
C．how to play an old game 
D．how people get along with each other 
【小題4】What can make the mechanophore’s warning system ineffective?
A．Paints B．Water C．Poor building materials D．The bright light

Why Doesn’t Anybody Copy Apple?
Apple’s products are the envy of the world. They have been spectacularly successful and are widely imitated, if not copied. The minute Apple crystallizes a product, everyone knows how to compete．This idea that the basis of competition is set by Apple and then the race is on to climb the path of improvement is unquestionable．When Apple releases a product that defines a category or dramatically changes the structure of an industry, it becomes obvious what needs to be built. But what I wonder is why everyone wants to copy Apple’s products but nobody wants to copy being Apple?
I can think of two reasons. Firstly, Apple is not worth copying because it's not successful; secondly, Apple’s success cannot be copied because it is a magical process．
There is a great deal of evidence for the first hypothesis. The idea of Apple being successful is not something reflected in its stock price．Being valued lower than the average company in the S&P（標(biāo)準(zhǔn)普爾）500 indicates that to whatever degree Apple was successful in the past, it's not seen by the vast majority of observers as successful in the future．Why should one bother copying Apple if it results in being punished with a low valuation? If one works really hard at innovation and then that innovation becomes commoditized（商品化）very quickly, why should one bother?
When innovation practitioners are asked what makes Apple successful, the answers regarding the cause of this success border on the mythical. The climax of this hypothesis is the “chief-sorcerer” theory of success which places one magician, like Steve Jobs, in charge of casting all the right spells（符咒）．
What about Apple’s own opinion of what makes it tick? Tim Cook refers to a great team and integration of hardware, software and services as unique Apple advantages. It’s a better explanation．Integration is something that can take a long time, but it is possible with great effort．A few companies are starting to make moves in that direction, but efforts are half-hearted．There is no “move the Earth” panic to become an integrated company from Samsung, Google or Microsoft．
My own suspicion is that Apple is more aware of what makes it special than it lets out． However, as Tim points out, it’s not a formula．It’s complex, it’s subtle, but it’s not magic．It’s a process that requires a degree of faith and courage．
【小題1】When a new product of Apple comes out, often it ______．

A．ruins an industry dramatically 
B．starts a revolution of an industry 
C．puts itself in an unbeatable position 
D．is soon overtaken by imitated products 
【小題2】According to the passage, other companies don’t “copy being Apple” because ______.
A． Apple is not a successful company 
B． they have no access to relevant resources 
C． It’s hard to find a magician like Steve Jobs 
D．being Apple takes more than time and efforts 
【小題3】We can infer from Para. 5 that ______．
A．other companies are dedicated to integration 
B．Apple itself is fully aware of its unique advantages 
C．Apple will hold the leading position in this industry  
D．other companies don't have a great team as Apple does 
【小題4】What does the author think of Tim Cook's statement?
A．Acceptable． B．Disappointing． C．Unquestionable． D．Convincing．

Boredom and Creativity
Most of us think of being bored at work as a negative experience, but a new study suggests it can have positive results including an increase in creativity because it gives us time to daydream.
That is the finding of Dr. Sandi Mann from the University of Central Lancashire. Dr. Mann conducted two studies. In the first experiment, 40 people were asked to carry out a boring task. They were told to copy numbers out of a telephone directory for 15 minutes. After that they were asked to complete another task. A pair of cups were given to each of them. Everyone tried to come up with different uses of the cups, and was given a chance to display their creativity. Meanwhile, another group of 40 people were just asked to come up with uses for the cups without doing any boring tasks before. It turned out that the 40 people who had first copied out the telephone numbers were more creative than the control group(對(duì)照組).
To see if daydreaming was a factor in this effect, a second boring task was introduced that allowed even more daydreaming than the boring writing task. This second study saw 30 people copying out the numbers as before, but also included a second group of 30 reading rather than writing them.
Again the researchers found that the people in the control group were least creative, but the people who had just read the names were more creative than those who had to write them out. This suggests that more passive boring activities, like reading or perhaps attending meetings, can lead to more creativity. Compared with reading, writing reduced the scope（范圍） for daydreaming. As a result, it reduces the  effects of boredom on creativity.
Dr. Mann says: “Boredom at work has always been seen as something to be avoided, but perhaps we should accept it in order to promote our creativity. What we want to do next is to see what the practical implications of this finding are. Do people who are bored at work become more creative in other areas of their work -- or do they go home and write novels?”  
【小題1】Who proved to be the most creative in the two studies?

A．The people who attended meetings.
B．The people who did the reading task.
C．The people who invented uses for cups.
D．The people who copied telephone numbers.
【小題2】The studies conducted by Dr. Mann indicate that creativity results from _______.
A．creative tasks
B．controlled activities
C．the range of daydreaming
D．reading and writing ability
【小題3】What is Dr. Mann’s attitude towards boredom at work?
A．Positive.
B．Skeptical.
C．Subjective.
D．Disapproving.
【小題4】What will Dr. Mann probably continue to research in their study?
A．The real causes of creativity.
B．The actual use of boredom.
C．The practical reasons of boredom.
D．The writing ability improved by boredom.
