听力原文：The climate of the west coast is the most moderate in Canada. Summers are cool an

听力原文： The climate of the west coast is the most moderate in Canada. Summers are cool and fairly dry and winters are mild, cloudy and wet. Even in mid-winter, average temperatures are usually above freezing.

The central plain from the Rocky Mountains to Great Lakes is characterized by cold winters, short but hot summers, and light snow and rain. Tile large water-surfaces of Central and Eastern Canada produce considerable modification in the climate. Southern Ontario and Quebec experience cold, damp winters and hot, humid summers.

Most of Atlantic Canada has a humid climate owing to its maritime character. Nevertheless, it experiences weather systems arriving from the dry, continental interior as well as from the sea. The combined influence of these systems creates some of the most variable day-to-day weather conditions to be encountered anywhere in Canada.

The north-central part of Canada is usually snow-covered for more than half of the year, with a frost-free period of barely two months. Rain is relatively light. Further north, on the islands along the Arctic coast and round Hudson Bay, the land. is always frozen. Average temperatures stay above freezing for only a few weeks of the year. The Arctic Islands and the northern border of the mainland do not have a summer season of the kind known in Southern Canada.

(33)

A．The Arctic coast.

B．The west coast.

C．The east coast.

D．The central plain.

听力原文：W: Everyone seems to be talking about climate change these days!

M: I'm not surprised. It's all these greenhouse gases--that's what's causing the problem!

W: What are the greenhouse gases？

M: You know, carbon dioxide, which comes mainly from the burning of fossil fuels, such as oil, gas and coal.

W: I've never understood why that's a problem.

M: Evidently these gases build up in the earth's atmosphere, and trap the heat from the sun.

W: And so this heat is warming the planet？

M: Exactly!

W: Well, isn't that good news？ I hate these cold winters we get!

M: Yes. But what's good for you here may not be so good for people elsewhere in the world. For the average world temperatures could rise. That can have a huge effect on local climates and ecosystems around the world,

W: So you really think that these floods we've seen m the news could be caused by global warming？

M: Sure! And also the droughts and the storms.

W: So what can we do about it？

M: It's not realistic to stop using fossil fuels today. But we can start trying to reduce carbon dioxide emissions.

W: And look for alternative sources of energy too, of course!

听力原文：Did you know that vegetables can be tricked into growing in climates they are not

听力原文： Did you know that vegetables can be tricked into growing in climates they are not accustomed to？ Cool climate vegetables like asparagus are now able to be grown in places as hot as Hawaii. In Hawaii marine engineers have been able to actually convince such vegetables that they're in cooler climates. That way they grow faster and taste better. What these engineers have been using is very simply cold water. How do they use it？ They place pipes in the soil and the cold water flows in through and then cools the air. This stimulates plant growth and enables gardeners in tropical climates to grow crops from cooler climates. Also some of these pipes are exposed to the air and they condense moisture and thus irrigate the garden. What's especially appealing about this process is that nothing damaging to the environment is being used. Another innovative use for cold ocean water is to cool buildings. Engineers believe that, for example, the entire western coast of the United States could be air-conditioned using seawater. We'll be back to discuss that possibility after this commercial message.

(26)

A．Irrigating desert areas.

B．Use for cold seawater.

C．Techniques for preserving the environment.

D．The importance of conserving energy.

听力原文：The oldest stone buildings in the world are the pyramids. They have stood for nea

听力原文： The oldest stone buildings in the world are the pyramids. They have stood for nearly 5,000 years, and it seems likely that they will continue to stand for thousands of years yet. There are over eighty of them scattered along the banks of the Nile, some of which are different in shape from the true pyramids.

Some of the pyramids still look much as they must have done when they were built thousands of years ago. Most of the damage suffered by others has been at the hands of men who were looking for treasure or, more often, for stone to use in modern buildings. The dry climate of Egypt has helped to preserve the pyramids, and their very shape has made them less likely to fall into ruin. These are good reasons why they can still be seen today, but perhaps the most important is that they were planned to last forever.

It is practically certain that plans were made for the building of the pyramids because the plans of other large works have fortunately been preserved. However, there are no writings or pictures to show us how the Egyptians planned or built the pyramids themselves. Consequently, we are only able to guess the methods used. Nevertheless, by examining the actual pyramids and various tools which have been found, archaeologists have formed a fairly clear picture of them.

(26)

A．The weather.

B．The corrosion of the river.

C．People in search of stone as building materials.

D．Bad planning.

A noted scientist, Ellsworth Huntington concluded from other men's work and his own among peoples in different climates that climate and temperature have a definite effect on our mental abilities.

He found that cool weather is much more favorable for creative thinking than is summer beat. This does not mean that all people are less intelligent in the summer than they are during the rest of the year. It does mean, however, that the mental abilities of large numbers of people tend to be lowest in the summer.

Spring appears to be the best period of the year for thinking. One mason may be that in the spring man's mental abilities am affected by the same factors that bring about great changes in all nature.
