听力原文： Experts say some farming activities are seriously dam-aging Earth’s environment. Bad farming methods can dam-age soil, forests and water supplies. They also have caused some plants and animals to disappear.
Two groups now say that bad farming methods are threatening the ability of farmers to produce enough food to feed the world population in the future.
The groups used satellite images, maps and modem equipment to study the effect of agriculture on the environment. The study found that the destruction of soil is wide-spread. Important organic nutrients are being removed from farmland.
Agriculture uses seventy percent of the freshwater in the world each year. The study found that many farmers are wasting water supplies. In addition, chemicals designed to protect crops may pollute waterways.
The report also says as much as thirty percent of the world's forests have been cut down so the land could be used for agriculture. This has led to a severe loss of wild-life and their environments.
Which is not mentioned in the passage as an aspect that farming activities are damaging7
A．Soil.
B．Human population.
C．Forest.
D．Water.

听力原文： Various kinds of nuclear weapons have been produced in the past few years by many countries. This is a new and a terrible development in the history of man. Very few events can be more frightful than a nuclear war. In a nuclear war, most of the world's population will be exterminated. (15[C])The few living Creatures that survive will be exposed to radiation or to electrical rays harmful to life. It has been said by scientists that many new diseases will be caused by radiation. (16[B])There will also be an acute shortage of food, for all the crops and stores will be poisoned by radiation. Most of the areas on which nuclear bombs have been dropped will be ruined. (17[A])Therefore the survivors of a nuclear war will be sick, hungry and homeless. It might be better; perhaps, to be killed in a nuclear war than to survive it. It would be better still for men to learn to live in peace with one another. If this can be achieved there will be no nuclear wars.

This new hospital has been designed to provide for all the health needs of the local population in this area. Not only does it have a fully equipped emergency room, this new hospital also has a dental clinic, a maternity ward for newborn children, and an operating room that should be able to handle most of the anticipated medical cases in the region. The hospital will establish a transfer system to cope with the few difficult cases that might be encountered. Whenever special types of surgery are required and this hospital is not considered adequate to provide for the needs, specialty surgeons can easily be flown in from other hospitals. Any case that cannot be handled here at this hospital will be sent to the state hospital by helicopter.
When the hospital is operating, it will have a full-time staff of three doctors as well as fourteen nurses and other employees. Sine the hospital will be employing employees from many different skill levels, the local economy will also benefit from this hospital.

听力原文： The limits of a person's intelligence are fixed at birth, but whether or not he reaches those limits will depend on his environment. It is easy to show that intelligence is, to some extent, something we are born with. The closer the blood relationship between two people, the closer they are likely to be in intelligence. Thus if we take two unrelated people at random from the population, it is likely that their degree of intelligence will be completely different. If on the other hand, we take two identical twins, they will very likely be as intelligent as each other. Relations like brothers and sisters, parents and children, usually have similar intelligence, and this clearly suggests that intelligence depend on birth.
Imagine now that we take two identical twins and put them in different environments. We might send one, for example, to a university and the other to a factory where the work is boring and fixed. We would soon find differences in intelligence developing, and this indicates that environments as well as birth plays a part. This conclusion is also suggested by the fact that people who live in close contact with each other, but who are not related at all, are likely to have similar degrees of intelligence.
In the development of one's intelligence, environment plays ______.
A．a less important role
B．an equally important role
C．an insignificant role
D．the least significant role

听力原文： It may be true, and we have to recognize obviously, that the population is badly housed and that we need more housing. However, housing uses up our scarce resources. It is pretty meaningless, therefore, to talk about providing more housing without taking into account the alternative use of resources. To provide more housing, when you have scarce resources, also implies, perhaps, making a choice between housing and other things which we could provide. Now, therefore, it's a question of priority. This is the problem which is true in U.K. market and it's also true in any housing market. The decision to provide more housing would involve giving up something. The question, therefore, arises. To what extent is the housing the greater priority than, say, health care and education so we come to the problem about choice. How are choices to be made in any economy, concerning how much housing is going to be provided？ Indeed, how are the choices going to be made in any economy about anything which is provided？.., and who is going to make that choice？ Basically, choices about how resources are allocated in any economy boil down to two possible ways of solving this problem. You either have the choices made directly by the government, or, the choices are made indirectly through the market.
What is the general topic of the lecture？
A．On housing.
B．On economy.
C．On marketing.
D．On choice of resources.
