听力原文： A beetle invasion in the United States has killed at least twenty million ash trees. The invasion of the emerald ash borer was first discovered near Detroit, Michigan, in 2002. Experts believe the small green insects arrived in the 1990's in shipments of goods from China.
The emerald ash borer has destroyed trees in the Midwest and as Far East in the United States as Maryland. The insects have also spread as far north as Ontario, Canada.
Ash trees can resist many diseases. But they cannot resist the emerald ash borer. It lays eggs on the bark. The young larva drill into and feed on the inner bark. This harms the ability of the tree to transport water and nutrition.
In some places, farmers .are using "detection trees". They have an area where bark has been cut away. The area circles the tree. The process weakens the tree. It makes them easier targets for borers, and shows if the insects are nearby.
Efforts to stop the spread of the emerald ash borer include cutting down affected trees. There are worries that the ash tree might disappear unless the invasion is controlled. To prepare for such a possibility, a government laboratory is asking people to send in the seeds from ash trees. It examines and X-rays the seeds to make sure that there are no living borer fertilized eggs. Only the best seeds are remained and then sent for storage in a seed bank. There, they are dried and frozen. Should the seeds ever be needed, the hope is that scientists might someday develop an ash tree that could resist the little green attackers.

听力原文： The recent increase in car stealing has alarmed the police, who are looking for what they now believe must be a well-organized gang of professional car thieves.
Most of the thefts have taken place in the rich residential areas round South-well Park, where last week alone, twenty-two car thefts were reported to the local police. Of course, only one has been found abandoned in Rocking-hill Palace road twenty miles away. The others have not been found yet, except for one which had been falsely reported missing. The owner later admitted that he had forgotten where he had parked it a few days before.
An interesting aspect of these thefts is that nearly all the missing vehicles have been taken from locked garages. The turners now admitted that they may have left the car doors unlocked, but only one owner was not certain whether he had locked the garage door. The police have therefore assumed that the gang find it easier to break into garages, where vehicles are often left unlocked at night, than into locked cars, parked on the road-side in day time or at night. They advise car owner to lock up their cars, even when they are kept in locked garages.

C．The increase in car stealing.
D．The increase in car owners.

听力原文： One of the main complaints of city residents, not surprisingly, is the lack of parking. This problem is partly caused by all the abandoned cars on the streets. It has been estimated by A to Z Towing, Inc., a nationwide tow-truck agency, that over one million cars are abandoned on the streets and alleyways of the nation's cities. Each year approximately a third of those cars are moved and destroyed. The rest of the cars which are not removed take up parking spaces and make neighborhoods look rundown.
A survey of twenty cities by A to Z reports that as much as 30 million dollars is spent annually to tow away and dismantle abandoned vehicles. One city alone, Los Angeles, spends five million dollars a year to control the accumulation of abandoned cars on its streets. Even though the city spends so much money on the program, it is always fighting a losing battle as more and more cars are constantly coming off the production line.
Boston, on the other hand, which spends most of its money on museums and libraries, does not appropriate tax money to clean abandoned cars off the streets. In Boston the problem has been dealt with by a non-profit governmental agency called Street Horizons, which uses the money from the recycling of the metal in the cars to pay for the cost of towing them The program in Boston sounds good although it has not completely reached financial independence from the federal government yet. Until a truly self-sufficient program for removing old cars is developed, it will remain a serious problem

A．Around four hundred thousand cars.
B．Thirty million old cars.
C．One million junked cars.
D．Five million cars altogether.
M: I am sorry I'm late, Ellen. This morning has been a real mess. I didn't think I was going to make it here at all.
W: Why are you late？ Our whole presentation depends on those graphs you are holding.
M: Yes, I know. I'll tell you about it later. First, let's see how we are doing for time. Two groups are still ahead of us, aren't they？ The presentation is on the rights of the consumer and the analysis of the stock market. That means I've got about twenty minutes to thaw out.
W: You do look cold. What happened？
M: I've been standing outside in Arctic temperatures for over an hour waiting for a bus.
W: Over an hour. But I thought your apartment was only a ten-minute bus ride to campus.
M: Under normal conditions. But the bus was delayed because of the weather and when I stepped into a drugstore to call home for a ride, the bus went by. As luck would have it, there was no one at home, so I had to wait another forty-five minutes for the next bus.
W: That's Murphy's Law, isn't it？ What was it he said, "If anything can go wrong, it will." Well, we still get twenty minutes to gather our wits together.
M: We'd better stop talking. People are turning around and looking at me.

The importance of environment in determining an individual's intelligence can be demonstrated by the case history of the identical twins, Peter and Mark. The twins had identical brain at birth. When the twins were three months old, their parents died, and they were placed in different homes. Peter was reared by parents of low intelligence in an isolated community with poor educational opportunities. Mark was reared in the home of well-to-do parents who had been to college. He was sent to good schools, and given every opportunity to be stimulated intellectually. This environmental difference continued until the twins were in their late teens, when they were given tests to measure their intelligence. Mark's I. Q. was 125, twenty five points higher than the average and fully forty points higher than his identical brother.

A．Human brains differ considerably.
B．The brain a person is born with is important in determining his intelligence.
C．An environmentally handicapped person won't attain his due level of intelligence.
D．Environment is important in determining a person's intelligence.
听力原文：W: Mr. Glieberman, do you see any change in high rate of broken marriages？
M: The divorce rate is beginning to level off and probably will begin to drop in the next year or two, though not significantly. The tightened economy has made it more difficult for troubled couples to handle all the costs associated with setting up separate households. Also, I believe there is a comeback of thought after the turbulent 60s and 70s that the family does have value. In the midst of change and family disintegration, people seem to have a greater desire now to create stability in their lives.
W: What is the divorce rate now？
M: About one in three marriages ends in divorce, a ratio far higher than it was twenty years ago when the philosophy was "we will tough it out no matter what." Society demands that for appearance's sake we stay together. Divorce no longer carries much disgrace. There is no way, for example, that Ronald Reagan, a divorced man, could have been elected president in 1960, And there are countless other divorced politicians who, years age, would have been voted out of office if they had even considered a divorce, let alone gotten one. The same was true in the corporate structure where divorced people rarely moved up the executive ladder. Now corporations welcome a divorced man because they can shift him around the country without worrying about relocating his family or making certain that they are happy.

A．Rise.
B．Fall.
C．V-shape.
D．Zigzag.
