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 Sicily Isles near the coast of England and spilled 120,000 tones 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 dependency 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.
1.What is the passage mainly talking about?

When we talk about positive thinking, we often use terms having to do with our hearts — open heart, pure heart or joyful heart. But new research from Duke University is making a closer connection, finding that a positive attitude may be helpful to people who have angina (心绞痛),a common heart condition.
Symptoms of this condition include chest pain or pressure because the heart is not receiving sufficient oxygen. Patients who displayed optimistic thought patterns, including having positive expectations about recovery, were 40 percent less likely to be hospitalized or require surgery than those who were not optimistic, according to the study. The researchers collected data from 2,400 patients who had diagnoses of angina.
An interesting additional finding from the patients' questionnaires was that the most optimistic patients were also the least likely to have histories of heart attack, heart failure or heart disease.
The researchers did not declare a causal relationship between positive thinking and better heart disease outcomes, however. There are multiple possible reasons for the results of the study, including the idea that patients who are healthier to begin with are more likely to expect to recover and regain good health.
But the study does represent a new way of looking at the situation. Now, in addition to a body of research that examines the relationship between depression and heart health, there is a new way of inquiry that asks whether positive thinking could be used as a strategy to improve outcomes.
Lead researcher Alexander Fanaroff, a fellow in the department of cardiology (心脏病学) at the Duke University Medical Center, told the Duke Chronicle that his next research question will find ways to improve attitudes among heart patients.
Perhaps his subjects could reflect on the word of the writer Anthony J. D'Angelo: "Smile, it is the key that fits the lock of everybody's heart."
1.How can people with angina get better according to the study?
A.By expecting more. B.By thinking positively.
C.By getting timely surgery. D.By taking more exercise.
2.What may be Alexander Fanaroff’s next research?
A.To explore how to improve patients’ attitudes.
B.To find out the ways to treat heart patients.
C.To learn the causes of heart diseases.
D.To test if positive attitudes help with health.
3.What can we learn from the text?
A.Optimistic people hardly get heart attack.
B.People's attitudes decide their overall health.
C.How positive thinking benefits heart health is unclear.
D.The reason why patients recover well is that they have no depression.
4.What may be the best title for the text?
A.Keep positive to get rid of illness
B.Angina, a kind of serious condition
C.Depression, a key cause of heart attack
D.Positive thinking makes hearts healthier

Last week, I bought an alarm system for about $ 450. It consisted of a control unit with three small units. I put the control unit in the sitting-room and fastened the other units by the front door, back door and living-room windows. The instructions told us to choose three numbers, so we chose 4, 9 and 1, the last three numbers of our telephone number.
Now I must explain how the alarm works:
l There is a power siren(警报器) in the control unit. It makes a very loud noise.
2 Each of the small units sends out beams or rays in different directions. If anything moves, it breaks a beam. This sends a signal to the control unit. The siren makes a noise which you can hear 50 meters away.
3. When we go to bed, I press the three buttons numbered 4, 9 and 1. Then we have 30 seconds to get out of the room before the alarm starts to work.
That night I slept soundly because I was sure that no burglar(夜贼) could get into our house. However, at about 2:10 a. m., I woke up and heard the siren. “There must be a burglar in the house,” Mary said. “What shall we do?”“I’ll go and see who’s there,” I said. “Stay here. Don’t make a noise.”I went downstairs quietly. When I reached the living-room, I switched on my torch and looked round the room. Then I turned the light on. I switched the siren off and searched the rooms downstairs. There was nothing wrong except that the back door was unlocked. I locked it, reset the alarm and went back to bed. About an hour later, the alarm started again. I jumped out of bed, fell over a chair in the dark and bumped into the bedroom door. Mary woke up and started hitting me with a torch. “Hey! Wait a minute!” I whispered. “It’s only me. I’m going downstairs to see what’s wrong.”I went down into the living-room and listened for a moment. The only sound I could hear was the siren. I turned on the light and then switched the siren off. As I did so, I glanced across at the curtains in front of the windows. I saw a house lizard (a kind of small animal) disappear behind the curtains.“Oh!” I said to myself. “That’s our burglar. ”When the lizard moved, it started the siren. I guessed that the alarm had been made in Europe, where there are no house lizards. Well. I won’t finish this story but if you want an alarm system free of charge, let me know. I’ll send you ours. We bought a dog this morning. It knows the difference between a lizard and a burglar.
1.The writer bought an alarm system to ________.
A.make sure that he got up early every day |
B.warn him when there were lizards in his house |
C.frighten burglars and tell him that somebody had got into the house |
D.make Mary feel safe to live in the large room |
2.The purpose of the three units was to________.
A.send a message to the control unit and start the siren |
B.sound their own sirens when the control unit told them so |
C.check that the control unit worked properly all the time |
D.give them enough light |
3.If the writer set the alarm and remained in the room for more than half a minute, _______.
A.nothing would happen |
B.the control unit would not work |
C.the siren would make a noise |
D.the dog would bark |
4.The purpose of the writer in writing the passage is to ________.
