There were no particular24 who influenced my choice of 25 and I especially like the areas in which I have worked because it 26 mathematics and many scientific disciplines， physics， chemistry and the life science.
My family and close relatives have included many 27 people for many generations. Several spent their lives in the 28 arts， many in commercial arts. There29 had been a scientist in the family. My family was， nevertheless， very 30 of my interest in science and would have probably31 been very supportive if I had a different interest. We lived in a community in which most families had emigrated to the United States from Europe. There was a great 32 among these families for their children to become welleducated and have successful careers in their33 professions. The New York City school system was excellent when I was growing up and 34 many great opportunities to the children. I attended college at the City College of New York， a very fine school that 35 many leading intellectuals. Looking back， I felt very lucky and appreciated for the way I came along.

Nearly 5，000 people below the age of 21 die because of excessive alcohol consumption each year. Oddly， this has triggered a new movement to lower the drinking age. In America， young people can vote， drive， marry divorce， hunt and go to war before alcohol is legally allowed to touch their lips. Many states once set their minimum drinkingage at 18. But in 1984 Ronald Reagan oversaw the passage of the “21 law”， which requires states to set 21 as the minimum drinkingage or risk losing 10% their highway funds. Now campaigners want to move it back. In the past， states have been too financially timid to challenge the 21 law. But calls for change are growing louder. Two local judges in South Carolina recently ruled that banning 18to 20yearolds from drinking or possessing alcohol is unconstitutional. Public officials， including the former attorney general of South Dakota， have called the 21 law a failure. The aboutface of Morris Chafetz， a doctor who served on the commission that recommended increasing the drinkingage to 21， has also raised eyebrows. This week he called it the most regrettable decision of his career.
Supporters of existing status， including the organization Mothers Against Drunk Driving， say that the law has helped avoid thousands of deaths. But doubters point out that other countries， like Canada， have seen similar declines， even though their drinkingage is 18. They also argue that barring young people from drinking does not stop them from consuming alcohol： it just makes them drink more quickly.
John McCardell， former president of Middlebury College in Vermont， is part of the Amethyst Initiative， a group of educators who are pushing for 18yearolds to be allowed to drink. “Those who have graduated from high school， have a clean record and completed an alcoholeducation programme should qualify for a drinking license，” he says， “in the same way that people who go to driving school receive a license to operate a vehicle.”
This is not the first time that Americans have desired a change in alcohol policy during a period of economic distress. Franklin Roosevelt lifted prohibition in 1933 amid the trouble of a depression.
40. All the U.S. State governments used o follow the “21 law” because .
A. its passage was supervised by Reagan personally
B. most citizens believed that it was reasonable
C. they couldnt afford to take the financial risk
D. it took much time and money to get a law passed
41. In Canada， where the drinking age is 18， .
A. young people want to begin drinking at a lower age
B. people are increasingly doubtful about the “18 law”
C. fewer and fewer people support the “18 law”
D. fewer young people die from drunk driving
42. John McCardell suggests that .
A.18yearolds should learn for a license before they can drink
B. a drinking school should be opened for high school students
C. one should get a license before they can drink
D. any 18yearolds should be qualified to drink 43. What did Franklin Roosevelt do during the 1933 depression？
A. He lifted the trouble of a depression.
B. He changed the alcohol policy.
C. He decided to ban alcohol.
D. He desired a change in alcohol policy.

How does food affect mood and mind？ The answer may lie in the chemistry of the brain and nervous system. Molecules called neurotransmitters （神经传递素） are chemical messengers. They carry a nerve impulse across the gap between nerve cells. The release of neurotransmitter molecules from one neuron and their attachment to receptor sites on another keep a nerve impulse moving.
Nerve impulses carry messages from the environment to the brain， for example， the pain you feel when you stub （踢碰） your toe. They also carry messages in the other direction， from the brain to the muscles. Thats why you back away from the obstacle that initiated the pain signal and exclaim， “Ouch！”
“Many neurotransmitters are built from the foods we eat，” says neuroscientist Eric Chudler of the University of Washington. Too little or too much of a particular nutrient in the diet can affect their production， Chudler says. For example， tryptophan from foods such as yogurt， milk， bananas， and eggs is required for the production of the neurotransmitter serotonin. Phenylalanine from beets， almonds， eggs， meat， and grains goes into making the neurotransmitter dopamine.
Dozens of neurotransmitters are known； hundreds may exist. Their effects depend on their amounts and where they work in the brain. The neurotransmitter serotonin， for example， is thought to produce feelings of calmness， relaxation， and contentment. Drugs that prevent it from being taken again （into the neuron that released it） are prescribed to treat depression. In at least some healthy， nondepressed people， carbohydrate foods seem to enhance serotonin production and produce similar effects. “It is the balance between different neurotransmitters that helps regulate mood，” Chudler says.
Proper nutrition may also enhance brainpower. Choline is a substance similar to the B vitamins. Its found in egg yolks， whole wheat， peanuts， milk， green peas， liver， beans， seafood， and soybeans. The brain uses it to make the neurotransmitter acetylcholine. To test the effects of choline on memory and learning， researchers at the Massachusetts Institute of Technology gave memory tests to college students before increasing the amount of choline in their subjects diets. Later， they retested. On the average， memories were better， and the students learned a list of unrelated words more easily. 44. The function of neurotransmitters can be best compared to that of .
A. a transport vehicleB. a protective shield
C. a power plantD. a food factory
45. Researchers at the Massachusetts Institute of Technology intended to find out .
A. how choline is produced out of foods
B. how choline is converted into acetylcholine
C. if the improvement of brainpower is related to choline
D. if the improvement of brainpower is related to proper diets
46. What is the message the author intends to convey？
A. The chemistry of the brain an nervous system.
B. The influence of foods on our food and mind.
C. The functions of neurotransmitters.
D. The importance of a balanced diet.

Cars and other road vehicles are the single main source of harmful nitrogen oxides.
Road transport remains the biggest source of harmful air pollution in the EU despite efforts to reduce emissions over the past decades.
A report published by the European Environment Agency （EE.） shows that it is the single main source of nitrogen oxides， carbon monoxide and nonmethane volatile organic compounds.
It is also the second most important source of PM10 and PM2.5 particles.
As well as road transport， manufacturing industries， construction， the residential sector and agriculture are the main sources of air pollution in Europe today， the agency said.
The EEA said， “Particulate matter from sources such as vehicle exhausts and residential heating can affect the lungs and harm people of all ages， but it is known to pose an extra risk to those with existing heart and respiratory problems.”
“Air pollutants are also responsible for the acidification of forests and water ecosystems， and eutrophication of soils and waters—leading to a limited supply of oxygen in rivers and lakes.”
