People in several American states may be surprised to see cars on city streets without a driver. Experimental driverless vehicles now are legal in Florida, Nevada and California. They are pointing the way to a future that is not far down the road. The high-tech company Google has a number of self-driving cars, which had covered 480,000 kilometers by August. Volvo is among the companies doing road tests and says it plans to sell driverless cars by 2020.
In September, California Governor Jerry Brown signed an act to allow autonomous vehicles on the roads of his state. “Today we’re looking at science fiction becoming tomorrow’s reality—the driverless car.” The technology for these cars includes cameras, radar and motion sensors. The systems have been improved through competitions sponsored by the US government agency DARPA. Engineer Richard Mason of the Rand Corporation helped design driverless vehicles for DARPA challenge races.
“Cars have become much more fuel-efficient, and new electronic features are making Hondas safer,” said Angie Nucci of Honda America. “A camera on the passenger-side mirror actually engaged on your guiding screen so you can safely change lanes.” Other safety features include warning systems on the front and the sides of the cars. These systems help drivers, but don’t replace them. Curator Leslie Kendall of the Petersen Automotive Museum said autonomous cars will make the high ways safer.
“By taking out drivers, you also remove most risks of an accident,” Kendall said. He said consumers, however, may be unwilling to lose control. “It may take them time to come to realize that the technology is indeed reliable, but it will have to prove itself first.”
Mason said the technology already works and the biggest challenge now is getting down the cost for driverless vehicles from hundreds of thousands of dollars to something more affordable. He said this will happen as the technology is improved.

Looking back on my childhood. I am convinced that naturalists are born and not made. Although we were brought up in the same way, my brothers and sisters soon abandoned their pressed flowers and insects. Unlike them, I had no ear for music and languages. I was not an early reader and I could not do mental maths.
Before World War I we spent our summer holidays in Hungary. I have only the dim memory of the house we lived in, of my room and my toys. Nor do I recall clearly the large family of grandparents, aunts, uncles and cousins who gathered next door. But I do have a crystal clear memory of dogs, the farm animals, the local birds and above all, the insects.
I am a naturalist, not a scientist. I have a strong love of the natural world, and my enthusiasm has led me into varied investigations. I love discussing my favorite topics and enjoy burning the midnight oil reading about other people’s observations and discoveries. Then something happens that brings these observations together in my conscious mind. Suddenly you fancy you see the answer to the riddle. Because it all seems to fit together .This has resulted in my publishing 300 papers and books. Which some may light honor, with the title of scientific research.
But curiosity, a keen eye, a good memory and enjoyment of the animal and plant world do not make a scientist? One of the outstanding and essential qualities required is self-discipline, a quality I lack. A scientist can be made a naturalist. If you can combine the two, you get the best of both worlds.
【小題1】According to the author, a born naturalist should first of all be _____
A.full of ambition | B.self-disciplined |
C.full of enthusiasm | D.knowledgeable |
A.lost his hearing when he was a child |
B.didn’t like his brothers and sisters |
C.was interested in flowers and insects in his childhood |
D.was born to a naturalist’s family |
A.just reads about other people observations and discoveries. |
B.Lacks some of the qualities required of scientist. |
C.Has a great deal of trouble doing mental arithmetic. |
D.Come up with solutions in most natural ways. |
A.He didn’t live very long with them |
B.He was too young when he lived with them. |
C.The family was extremely large. |
D.He was fully occupied with observing nature. |
A.The author believes that a born naturalist cannot be scientist. |
B.The author read a lot of books about the natural world and oil industry |
C.The author’s brothers and sisters were good at music and languages. |
D.The author spent a lot of time working on riddles. |

While learning the science lessons, I used to get a doubt--why ear, nose, tongue and eyes should be called as special senses? The basic reason is that these are the channels through which we maintain contact with the surroundings. Though apparently it may feel like these are individual sensory organs, they do show some connectivity. Interestingly, our hearing is less sharp after we eat a heavy food. Isn’t it good for a sound nap after a stomach-full meal? That does not mean we go deaf after a meal, but the hearing pitch(強(qiáng)度)does change after a heavy meal.
We usually give credit of the taste to our tongue, but do you know that unless saliva(唾液)dissolves something, our tongue cannot recognize the taste of the food eaten. Taste is nothing but the food chemicals dissolved in the saliva being sensed by the taste buds(味蕾)present on the tongue. Try to dry off your tongue and mouth with a tissue paper and then taste something.
Women are much better smellers than men. They are born with this characteristic ability and can correctly recognize the exact fragrance of the sample. We all can store almost 50,000 different smells, which are strongly tied to the memories.
Pupils(瞳孔)do not respond to light alone, but to the slightest bit of noise around too. Thus surgeons, watchmakers and those professionals who have to perform a much delicate job do prefer to have a sound-free environment. Even a small noise can enlarge their pupils, change the focus and make their vision less clear.
Each and every one of us has a particular or individualistic or characteristic smell, which is unique to us, except the twins. This smell is very subtle yet can be sensed even by a newborn. It may be due to this smell that the newborn recognizes the presence of his parents around.
【小題1】What may happen after you have had a rich lunch?
A.Your eyes become weak and can not see well. |
B.You may feel energetic and fresh. |
C.Your hearing pitch may be decreased. |
D.Your tongue may lose the function of taste. |
A.Our tongues can’t be dried while eating something. |
B.If your tongue is dried without any saliva on it, it will not work. |
C.A tissue paper is the only thing that can be used to dry our tongues. |
D.If your tongue is dried with a tissue paper, it may work as well as before. |
A.The number of sensory organs. |
B.The functions of sensory organs. |
C.The particular smell of a person. |
D.The style of one’s behavior. |
A.The Sensitivity of Sensory Organs |
B.The Functions and Connections of Sensory Organs |
C.A Newborn’s Sensory Organs |
D.Different Senses Between Men and Woman |

How do you know if your home is an easy aim for thefts? Around the holidays, many families don’t consider taking proper measures to prevent their homes from suffering holiday thefts. With just a few simple steps, you can better make sure of the safety of your home during all of the holiday celebrations. Here are a few tips for making it difficult to tell you are away from home.
●Either have a trusted neighbor pick up your mail and newspapers, or tell your mailperson to hold your mail until you return. Nothing says “Hey, we are not home!” like when your postbox is filled with all kinds of mails and you have many different newspapers in your driveway.
● Set several different lights in your house on random timers(隨機(jī)定時(shí)器). Don't leave your outdoor lights on all the time. Instead, put your outside light on timers to be on during the nights. If an outdoor light remains on for days at a time, it means that nobody is home to turn it off.
● If you have pets that you are not taking with you on vacation, leave them with friend, rather than having someone come into your house every day to take care of them. When thefts see a neighbor or friend entering your house every day, they will know you are not home.
● Close all your curtains when you leave town. This is effective to deter possible thefts, as no one can see what is in your house. If they don't know what there is to take, then the risk is even greater for them to break in.
This article just has suggested a few tips to help you keep your house safe on holiday. Nothing can truly protect your home unless you have it monitored by a professional home security system.
【小題1】What is the main idea of the passage?
A.To let the outdoor lights on all the time. |

In the north of Scotland there is a lake called Loch Ness. It is the biggest lake in Britain. It is over thirty kilometres long and in places nearly 300 meters deep. It is cold and dark and not many people went there until after 1930. Then a road was made around the lake. Holiday makers began to use the road, and this was when the stories began.
Someone said that he had seen a monster in the lake. He said it was twelve meters long. It had a long neck and a small head. Then someone else said he had seen it. Others said the same thing and in 1933 a London doctor took a photo. It looked like a monster with a long neck and a thick body but the photo was not dear. The newspapers printed the picture and called it the Loch Ness monster, or "Nessie".
Then the argument began. Some people, however, were certain there was something living in the lake. Others said there was nothing there.
In 1961, a lot of people joined together to make a real effort to see and photograph the monster if there was one! Several times people thought they saw something but after ten years there was still no real proof.
Later underwater television cameras were used, but no one found any real proof. However, they did find something interesting: a huge underwater cave. It was big enough to be home of a monster, but of course, this was not a proof.
In 1975, however, some American scientists formed a search group. They used an underwater camera. It took pictures every seventy seconds. Some of the pictures seemed to show a red-brown creature. Its body was about four meters long and had a very ugly head on the end of a four meter neck. Many people then began to believe in the monster. But even today we can not be certain.
【小題1】Before 1930, ____.
A.few people went to Loch Ness Lake |
B.many people had been there |
C.nobody went to the lake |
D.nobody knew about the lake |
A.It looked like a horse. |
B.It was a creature with a long neck and a small head. |
C.It looked beautiful. |
D.It was tiny and pretty. |
A.An American |
B.A television camera |
C.A holiday-maker |
D.A doctor from London |
A.found the monster itself |
B.found a huge cave under water |
C.believed that there wasn't any monster at all |

A rainforest is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely falling below 16℃. Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate. Without the forest cover, these areas would reflect more heat into the atmosphere,warming the rest of the world. Losing the rainforests may also influence wind and rainfall patterns, potentially causing certain natural disasters all over the world.
In the past hundred years, humans have begun destroying rainforests in search of three major resources : land for crops, wood for paper and other products, land for raising farm animals. This action affects the environment as a whole. For example,a lot of carbon dioxide in the air comes from burning the rainforests. People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit. There are two main reasons for this. Firstly, when people cut down trees, generally they can only use the land for a year or two. Secondly, cutting large sections of rainforests may provide a good supply of wood right now, but in the long run it actually reduces the world’ s wood supply.Rainforests are often called the world’s drug store. More than 25% of the medicines we use today come from plants in rainforests. However, fewer than 1% of rainforest plants have been examined for their medical value. It is extremely likely that our best chance to cure diseases lies somewhere in the world’s shrinking rainforests.
【小題1】 Rainforests can help to adjust the climate because they________.
A.reflect more heat into the atmosphere |
B.bring about high rainfall throughout the world |
C.rarely cause the temperature to drop lower than 16℃ |
D.a(chǎn)bsorb the heat from the sun, reducing the effect of heat from the sun on the earth |
A.We will lose much more than we can gain. |
B.Humans have begun destroying rainforests. |
C.People have a strong desire for resources. |
D.Much carbon dioxide comes from burning rainforests. |
A.we can get enough resources without rainforests |
B.there is great medicine potential in rainforests |
C.we will grow fewer kinds of crops in the gained land |
D.the level of annual rainfall affects wind patterns |
A.How to Save Rainforests? |
B.How to Protect Nature? |

Sometimes, the simplest ideas are the best. For example, to absorb heat from the sun to heat water,you need large, flat, black surfaces. One way to do that is to build those surfaces specially, on the roofs of buildings. But why go to all that trouble when cities are full of black surfaces already, in the form of asphalt (柏油) roads?
Ten years ago, this thought came into the mind of Arian de Bondt, a Dutch engineer. He finally persuaded his boss to follow it up. The result is that their building is now heated in winter and cooled in summer by a system that relies on the surface of the road outside.
The heat-collector is a system of connected water pipes. Most of them run from one side of the street to the other, just under the asphalt road. Some, however, dive deep into the groun.
When the street surface gets hot in summer, water pumped through the pipes picks up this heat and takes itunderground through one of the diving pipes. At a depth of 100 metres lies a natural aquifer(蓄水層) into which heat several heat exchangers (交換器) have been built. The hot water from the street runs through these exchangers, warming the ground-water, before returning to the surface through another pipe. The aquifer is thus used as a heat store.
In winter, the working system is changed slightly. Water is pumped through the heat exchangers to pick up the heat stored during summer. This water goes into the building and is used to warm the place up. After performing that task, it is pumped under the asphalt and its remaining heat keeps the road free of snow and ice.
【小題1】Which of the following is true according to the first two paragraphs?
A.Arian de Bondt got his idea from his boss. |
B.Large, flat, black surfaces need to be built in cities. |
C.The Dutch engineer's system has been widely used. |
D.Heat can also be collected from asphalt roads. |
A.To absorb heat from the sun. |
B.To store heat for future use. |
C.To turn solar energy into heat energy. |
D.To carry heat down below the surface. |
A.some pipes have to be re-arranged in winter |
B.the system can do more than warming up the building |
C.the exchangers will pick up heat from the street surface |
D.less heat may be collected in winter than in summer |
A.What we shall do if the system goes wrong . |
B.What shall we do if there are no asphalt roads |
C.How the system cools the building in summer . |
D.How the system collects heat in spring and autumn. |

When you tidy your messy bedroom,it gets a lot easier to find things.Dreams may work the same way for a messy brain,helping you learn by organizing memories and ideas.
To test how much dreams can help learning,Robert Stickgold had some students play a shapefitting game called Tetris (俄羅斯方塊) for a few hours and then go to sleep.Soon they were dreaming of falling Tetris shapes.Interestingly,the worst Tetris players had the most Tetris dreams and improved their game the most.Similar tests have shown the same results for all kinds of skills.
As we dream,many important tasks are getting done.The brain decides what to keep and what to forget.It is connecting new experiences to older learning.In fact,the brain is learning all night long.
Another important task of dreams may be to help us deal with emotions (情緒).At night,emotions are in the driver’s seat.People who have had an upsetting experience often dream about it afterward.Often the dream event changes somehow—another way the brain tries to make the memory less upset.So if your best friend moves away,you might dream that you’re the one who’s moving.In fact,dreams have a proven power to improve mood,and people who dream about what’s bothering them usually feel better sooner than those who don’t.
Everybody dreams for a couple of hours every night—in the course of your life,you’ll spend about 25 years asleep and 6 years dreaming.There’s probably no single answer to the question why we dream,but there doesn’t have to be.One dream might help you remember your math facts,while another might lead to a new invention,or give you a fun,crazy story to tell your friends.It’s all in a night’s work for our busy,mysterious brains.
【小題1】Robert Stickgold’s test shows that________.
A.games are useful for memory |
B.dreams can help improve skills |
C.players stop learning in dreams |
D.tasks can only be settled through dreams |
A.dreams can get rid of sufferings |
B.only drivers can deal with emotions |
C.one may be less upset after a dream |
D.dreams can copy what one experienced |
A.Dreaming does harm to one’s mood. |
B.Dreaming affects the quality of sleep. |
C.It’s hard to find out the secrets of dreaming. |
D.It’s not so important to know the cause of dreaming. |
A.Dreams and memories. | B.Dreams and emotions. |
C.The benefits of dreams. | D.The patterns of dreams. |
A.Entertainment. | B.Tourism. |
