With alarming regularity, we read about oil tankers having accidents near land and the terrible consequences of the oil spills (泄露) on people, nature, and the environment.
Millions of dollars have been used in developing special chemicals to help dismiss the spills and to clean up the animals, beaches, and land spoiled by the oil.Unfortunately, when many of these chemicals are used, more damage is caused to the environment, especially to lives in the sea.
Of all of today's environmental disasters, an oil spill may actually be one of the least serious.Although oil is poisonous, it is a natural material.In the end, it breaks down naturally.There are, of course, long-term effects, but it is usually more serious in the short term.
Nature by itself works better than chemical materials, but when there is a spill we demand that governments act immediately with as much hi-tech knowledge as possible.In 1967 the tanker Torrey Canyon sank off the Scilly Isles near the coast of England and spilled 120,000 tons of oil into the ocean.If you go there today, you will find it hard to see any sign that it ever happened.
Governments seem to accept the risk of transporting millions of tons of oil by ship every day so that we can fill up our cars and drive around and cause even more environmental damage.Interestingly, the biggest companies in the world produce cars, and the next biggest supply the gasoline to make them run.
We should be thinking more about reducing our dependence on oil.Governments should be encouraging research into new technologies, such as cars run by solar power (太阳能) , electricity, hydrogen, and so on.Much of this research has, in the past, been held back by the oil, gas, and coal.
If the world's millions of cars were 10% more efficient (高效的)—and the industry could easily produce cars at least twice as efficient we would need many fewer tankers crossing the oceans each year.If this happened, the risks of oil spills would be reduced, and the air we breathe would be cleaner and fresher, too..What is the passage mainly talking about?

Plants are very important living things. Life could not go on if there were no plants. This is because plants can make food from air, water and sunlight. Animals and man cannot make food from air, water and sunlight. Animals get their food by eating plants and other animals. Therefore animals and man need plants in order to live. This is why we find that there are so many plants around us.
If you look carefully at the plants around you, you will find that there are two kinds of plants: flowering plants and non-flowering plants.
Flowering plants can make seeds. The seeds are protected by the fruits. Some fruits have one seed, some have two, three or four, and some have many seeds. But a few fruits have no seeds at all. An example of a fruit without seeds is the banana fruit.
Most non-flowering plants do not grow from seeds. They grow from spores(胚芽). Spores are very small. Some spores are so small and light that they can float in the air. We may say that spores are quite the same as seeds. When these spores are all on wet and shady places, they usually grow into new plants. The main idea of the first paragraph is that ______.
A.plants are important for life | B.plants cannot grow without air |
C.there are many plants in the world | D.we can not live without water |
Plants can make food from______.
A.flower, water and air | B.water, sunlight and air |
C.air, water and soil | D.air, sun and light |
What can we infer(推断) from the passage ?
A.Of all living things animals are most important | B.Spores are seeds |
C.All fruits of flowering plants have seeds | D.Without plants, man will die out |
This passage may be taken from______.
A.a medicine book | B.a novel |
C.a science magazine | D.an experiment report |
The underlined word “protected” in the third paragraph can be replaced by ______.
A.damaged | B.polluted | C.prevented | D.guarded |
They leap from helicopters or speeding boats, bringing aid to swimmers who get into trouble off Italy’s popular beaches.
Hundreds of specially trained dogs from Italy’s corps of canine(犬类的) lifeguards set out each summer to help swimmers in need of rescue.
These "life dogs" wear a harness that victims can grab to be dragged back to shore, and unlike human lifeguards, they can easily jump from helicopters and speeding boats to reach swimmers in trouble.
With millions flocking to Italy’s crowded beaches each summer, the Italian Coast Guard says it rescues about 3,000 people every year —and their canine helpers have saved several lives.
It takes three years for the canines to reach expert rescue status, and currently 300 dogs are fully trained for duty, said Roberto Gasbarri, who directs the Italian School of Canine Lifeguards program.
"Dogs are of good physical strength. They can increase the speed at which victims are rescued," Gasbarri said.
"The dog becomes a sort of intelligent lifebuoy(救生圈). It is a buoy that goes by itself to a person in need of help, and comes back to the shore also by himself, choosing the best landing point and swimming through the safest currents," he said.
The school will train any breed, as long as they weigh at least 30 kilograms, but New found lands and golden retrievers are most commonly used because they are good at swimming. Each dog works together with a human lifeguard, who also acts as the animal’s trainer.
"Being retrievers, they set out to pick up anything we tell them, be it a human being, an object, or a fish, and they bring it back to the shore," said lifeguard Monia Luciani. "They do not associate it with a physical activity, but it is rather a game for them."The dogs wear a harness so that __________.
The dogs are helpful to _________.
Why does the school usually choose to train the New found lands and golden retrievers?
___________________________________.How do the dogs regard the pickup training?

It seems hard to watch someone yawn and not to yawn ourselves. Even reading about yawning can make you do it. Now, a new study has found why yawning has such a powerful force.
Yawning when others yawn, the study suggests, is a sign of pity and a form of social connection. Kids don’t develop this deeply rooted behavior until around age four, the study found. Kids with autism (自闭症) are less likely to catch yawns. In the most serious cases, they never do. Yawning might help doctors to see whether the children are developing rightly. The work could also lead to a better understanding of the ways that people communicate and connect.
"Emotional infection seems to be a born thing that connects us together," said Molly Helt, a graduate student in psychology at the University of Connecticut. "Yawning may be part of that." Inspiration for her study came when she tried to get her own autistic son to clear his ears on an airplane. She repeatedly yawned at him, hoping he would yawn back. He never did.
"The fact that autistic kids don’t do it might mean they’re really missing out on that emotional connection with people around them," she said. "The biggest thing people try to figure out after birth is how we become humans and understand that humans have minds that are different from others’," she added. "Autistic people never seem to understand that."
Like infectious laughter and crying, scientists have found that yawning is a shared experience that promotes social connection. Helt said it could fight stress after a period of being nervous and spread a feeling of calm through a group.What does the new study suggest, according to the first two paragraphs?
A.It is easy to stop yawning when you see others yawn. |
B.Yawning has some mysterious force which is related to God. |
C.Children follow others in yawning just after they are born. |
D.Yawning is a form of communication. |
According to Molly Helt, _________________.
A.emotions are infectious, but yawning is not |
B.yawning helps clear ears on planes |
C.humans differ from animals because they communicate with others |
D.yawning is a kind of emotional connection among humans |
Which of the following is NOT true about yawning?
A.It is natural to yawn back if people around you yawn. |
B.Some kids are too young to yawn after others. |
C.Yawning can be used to test children’s development. |
D.Kids with autism yawn easily when others yawn. |
The author implies in the last paragraph that ________.
A.it is bad manners to yawn on some social occasions |
B.yawning can make people feel relaxed |
C.yawning is different from infectious laughter and crying in theory |
D.the more you yawn, the happier you will be |
How difficult change is depends a lot on your attitude towards it and your resistance to it. Your attitude to change can make the whole transformation process much easier.
Imagine change as a pair of shoes and this will help you understand change and how it works. I am sure that you have ever had a comfortable pair of shoes in your life. A pair of shoes is so comfortable that you really don’t want to get rid of them.
You know you need a new pair, and may even have them, but you don’t want to wear them because you are comfortable with your current pair. Besides, the new pair may hurt your feet, give you blisters(水疱) or be awkward to wear to start with. So, you resist the new shoes. However, you know that this new pair would be much better for your feet, and after the initial discomfort they would probably be even more comfortable, yet you still resist.
Do you know I’m doing this now? I’m wearing my comfortable shoes and they feel good. They have a hole in each heel, and the sole is starting to fall off, but I’m persisting in wearing them.
This describes change exactly; change of our habits, change of our thought patterns. We stick with the old patterns because they are comfortable. Yet once we get over the initial pain of the transformation, the new pattern will be comfortable and feel good until the time comes when we need another new pair of shoes.Why do people prefer old shoes to new ones?
A.They have much emotion in the old ones. |
B.They are more comfortable. |
C.New shoes always harm the feet. |
D.They look better than the new ones. |
According to the passage, we know that people ______.
A.don’t realize the benefit of the new shoes very well |
B.are positive and open-minded to accept new things |
C.actually know the change will finally be good for them |
D.don’t accept new patterns because they are not good |
What can be inferred from the passage?
A.Once we form a habit, it’s difficult to change it. |
B.Most people pay more attention to the future life. |
C.One’s attitude towards something is usually traditional. |
D.The more often we change, the better our life will be. |
It was the first day of second grade, and Sarah had been looking forward to this moment. The night before, she laid out her favorite clothes: a white coat and a bright yellow shirt.
When having breakfast, Sarah dropped some food on her shirt, so she had to change into her second-best clothes, blue jeans and a Jonas Brothers T-shirt.
After breakfast Sarah rushed to catch the school bus and when she was just reaching the door the bus driver opened it. The door hit right in Sarah’s face and blood dripped from her nose. The driver wanted to send her home, but she refused, "It is the most important day of the year! I can’t miss it!"
Before classes, Sarah went to her favorite swing. When rising high, she saw her best friend little Jack. She let go of the swing and waved to him with one hand. Unfortunately, she flew out of the swing and landed hard on the sand, breaking a leg and an arm. As she lay in the sand, she noticed a shiny thing on the ground beside her. With her good hand she took it.
When Sarah’ mother rushed into the ward she was surprised by what she saw: her girl was lying in bed with an arm and a leg in the splint (夹板), a broken nose, and blood stains on her second-best clothes. Expecting to see her child crying, she was confused when she saw a big, bright smile on Sarah’s face.
"Sarah, look at you!" her mother cried. "You were hurt so badly and why are you smiling?"
"Look, Mommy, I found a diamond!" Sarah laughed.
