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.

听力原文： After shopping for most of the day, a couple return to find their car has been stolen. They are shocked and very upset because they just bought it a month ago. They go to the police station to make a full report. Then, a police officer drives them back to the parking lot to see if any evidence can be found at the scene of the crime. To their surprise, the ear has been returned.
There is an envelope stuck on the car with a note of apology and two tickets to a concert. The note reads," I apologize for taking your car, but my wife was having a baby and I had to use your car to rush her to the hospital. Please forgive the inconvenience. Here are two tickets for tonight's concert."
The couple feel relieved. After all, most human beings are kind, they think. They even feel glad that their car was used in such a way. It might perhaps have saved two lives, the mother's and the baby's. They go to the concert, enjoy the music to their hearts' content, and return home late. To their astonishment, they find their house has been robbed. Valuable goods have been taken. The downstairs living room is in a mess. Even the kitchen is not spared. And, there is a note on the door reading, "Well, you still have your car. I have to put my newly-born kid through college somehow, don't I？"
