Driving In America
Keep Right
The traffic follows the “keep right rule”. While driving, drive on the right side of the road. On one-way, multiple lanes(车道) road, the right-most lane would be slowest and left-most lane is fastest.
Hand Signals
Though indicators(车的指示灯) are used for the purpose of showing which direction you are going, knowing some hand signals is very important and are usually always asked in a driving test. When you want to turn right, you can put your left hand out of the window and point upward. When you want to make a left turn, you can reach your left arm out of the window and point to the left. If you want to slow down or stop, you can just point downward.
School Buses
Yellow school buses have flashing red lights and stop signs that reach out from the driver’s side. The drivers use these warning signals when letting pupils on and off. No matter which side of the road you are traveling on, if you come upon a school bus with its lights flashing and a stop sign used, you must stop. It’s the law. Remain stopped until the lights stop flashing or the stop sign is removed.
Using the Horn
Using horns is not common in America. Actually they are very rarely used. You may use your horn to warn walkers or other drivers of possible trouble or to avoid accidents. Do not use your horn to express anger or complain about other drivers’ mistakes or to try to get a slow driver to move faster.
1.If Freddy is asked to go to Florida in the shortest time from Missouri, on which lane in the picture below should he drive his car according to Paragraph 1?

What will power your house in the future? Nuclear, wind, or solar power? According to scientists at the Massachusetts Institute of Technology (MIT) in the US, it might be leaves – but man-made ones.
Natural leaves are able to change sunlight and water into energy. It is known as photosynthesis (光合作用). Now researchers have found a way to copy this seemingly simple process.
The man-made leaf developed by Daniel Nocera and his partners at MIT can be seen as a special chip with catalysts (催化剂). Similar to natural leaves, it can split water into hydrogen and oxygen when put into a bucket of water. The hydrogen and oxygen gases are then stored in a fuel cell (电池), which uses those two materials to produce electricity.
A man-made leaf is not a new idea. The first man-made leaf was invented in 1997 but was too expensive and changeable for practical use. The new leaf, on the contrary, is made of cheap materials, easy to use and highly stable. In laboratory studies, Nocera showed that a man-made leaf prototype (原型) could operate continuously for at least 45 hours without a drop in activity.
The wonderful improvements come from Nocera’s recent discovery of several powerful, new, inexpensive catalysts. These catalysts make the energy change inside the leaf more efficient with water and sunlight. Right now, the new leaf is about 10 times more efficient at carrying out photosynthesis than a natural one. Besides, the machine can run in whatever water is available; that is, it doesn’t need pure water. This is important for some countries that don’t have enough pure water.
With the goal to “make each home its own power station” and “giving energy to the poor”, scientists believe that the new machine could be widely used in developing countries, especially in India and rural China.
1.What will give power to our house in the future, according to MIT?
A. Man-made leaves. B. Nuclear.
C. Solar power. D. Wind.
2.Which of the following orders correctly shows how the man-made leaf is used to produce electricity?
a. man-made leaves split water into hydrogen and oxygen
b. the hydrogen and oxygen gases are stored in a fuel cell
c. the man-made leaves are put in water
d. the fuel cell uses hydrogen and oxygen to produce electricity
A. cbad. B. bcad.
C. cabd. D. cadb.
3.What does the underlined “stable” in the 4th paragraph mean?
A. Secure. B. Powerful.
C. Unnatural. D. Unchangeable.
4.The aim of the scientists at MIT in developing the new man-made leaves is to .
A. build up more power stations in the world
B. provide cheaper energy for developing countries
C. offer people in developing countries access to pure water
D. gain a deeper understanding of the photosynthesis process

Section B
Directions: Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.
(A)
The elephant was lying heavily on its side, fast asleep. A few dogs started barking at it. The elephant woke up in a terrible anger: it chased the dogs into the village where they ran for safety.
That didn't stop the elephant. It destroyed a dozen houses and injured several people. The villagers were scared and angry. Then someone suggested calling Parbati, the elephant princess.
Parbati Barua's father was a hunter of tigers and an elephant tamer. He taught Parbati to ride an elephant before she could even walk. He also taught her the dangerous art of the elephant round-up -- how to catch wild elephants.
Parbati hasn't always lived in the jungle. After a happy childhood hunting with her father, she was sent to boarding school in the city. But Parbati never got used to being there and many years later she went back to her old fife. "Life in the city is too dull. Catching elephants is an adventure and the excitement lasts for days after the chase," she says.
But Parbati doesn't catch elephants just for fun. "My work," she says, "is to rescue man from the elephants, and to keep the elephants safe from man." And this is exactly what Parbati has been doing for many years. Increasingly, the Indian elephant is angry: for many years, illegal hunters have attacked it and its home in the jungle has been reduced to small pieces of land. It is now fighting back. Whenever wild elephants enter a tea garden or a village, Parbati is called to
guide the animals back to the jungle before they can kill.
The work of an elephant tamer also involves love and devotion. A good elephant tamer will spend hours a day singing love songs to a newly captured elephant. "Eventually they grow to love their tamers and never forget them. They are also more loyal than humans," she said, as she climbed up one of her elephants and sat on the giant, happy animal. An elephant princess indeed!
1.For Parbati, catching elephants is mainly to .
A. get long lasting excitement B. keep both man and elephants safe
C. send them back to the jungle D. make the angry elephants tame
2.Before Parbati studied in a boarding school, .
A. she spent her time hunting with her father
B. she learned how to sing love songs
C. she had already been called an elephant princess
D. she was taught how to hunt tigers
3.Indian elephants are getting increasingly angry and they revenge because __________.
A. they are caught and sent for heavy work
B. illegal hunters capture them and kill them
C. they are attacked and their land gets limited
D. dogs often bark at them and chase them
4.The passage starts with an elephant story in order to explain that in India _________.
A. people easily fall victim to elephants' attacks
B. the man-elephant relationship is getting worse
C. elephant tamers are in short supply
D. dogs are as powerful as elephants

She turned up at the doorstep of my house in Cornwall. No way could I have sent her away. No way, not me anyway. Maybe someone had kicked her out of their car the night before. "We're moving house.” "No space for her any more with the baby coming." "We never really wanted her, but what could we have done? She was a present." People find all sorts of excuses for abandoning an animal. And she was one of the most beautiful dogs I had ever seen.
I called her Goldie. If I had known what was going to happen I would have given her a more creative name. She was so unsettled during those first few days. She hardly ate anything and had such an air of sadness about her. There was nothing I could do to make her happy, it seemed. Heaven knows what had happened to her at her former owner's. But eventually at the end of the first week she calmed down. Always by my side, whether we were out on one of our long walks or sitting by the fire.
That's why it was such a shock when she pulled away from me one day when we were out for a walk. We were a long way from home, when she started barking and getting very restless. Eventually I couldn't hold her any longer and she raced off down the road towards a farmhouse in the distance as fast as she could.
By the time I reached the farm I was very tired and upset with Goldie. But when I saw her licking (舔) the four puppies (幼犬) I started to feel sympathy towards them. "We didn't know what had happened to her," said the woman at the door. "I took her for a walk one day, soon after the puppies were born, and she just disappeared." "She must have tried to come back to them and got lost," added a boy from behind her.
I must admit I do miss Goldie, but I've got Nugget now, and she looks just like her mother. And I've learnt a good lesson: not to judge people.
1.In her first few days at the author's house, Goldie .
A. felt worried B. was angry
C. ate a little D. sat by the fire
2.Goldie rushed off to a farmhouse one day because she .
A. saw her puppies B. heard familiar barking
C. wanted to leave the author D. found her way to her old home
3.The passage is organized in order of .
A. time B. effectiveness
C. importance D. complexity
