听力原文： Every country tends to accept its own way of life as being the normal one and to praise or criticize others as they are similar to or different from it. And unfortunately, our picture of the people and the way of life of other countries is often a distorted one.
Here is a great argument in favor of foreign travel and learning foreign languages. It is only by traveling in, or living in. a country and getting to know its citizens and their language, that one can find out what a country and its people are really like. And the knowledge one gains this way frequently turns out to be different from the second-hand information gathered from other sources. How often we find that the foreigners whom we thought to be such different people from ourselves are not very different after all! Differences between peoples do, of course exist and, one hopes, will always continue to do so. The world will be a dull place indeed when all the different nationalities behave exactly alike, and some people might say that we are rapidly approaching this state of affairs. With the much greater rapidity and ease of travel, there might seem to be some truth in this at least as far as Europe is concerned, However this may be, at least, the greater ease of travel today has revealed to more people than ever before that the Englishman or Frenchman or German is not some different kind of animal from themselves.

听力原文： Do you know that vegetables can be grown in climate they are not accustomed to？ Cool climate vegetables are now able to be grown in places as hot as Hawaii.
In Hawaii, engineers have been able to actually make those vegetables live in cooler climates. That way they grow faster and taste better. What these engineers have been using is cold seawater. The temperature of seawater is much lower than the air temperature.
How do they use it？ They placed pipes in the soil and the cold water flowing through them cools the earth. 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 make the moisture form. little water drops and thus irrigate the gardens. What is especially appealing about this process is that nothing damaging to the natural environment is being used.
Another innovative use for cold ocean water is to coal buildings. Engineers believe that, for example, the entire west coast of the United States could be air-conditioned using seawater.
We all know there are certain types of chemicals used in air conditioners, which not only pollute the air but also bring damage to the ozone. If we could cool the city by using seawater, the environment of the whole city will be improved and the ozone will be protected, which will be beneficial to ourselves in return.
