Unit 7 The natural world
交际英语
Tina and Rudy are discussing their fears. (Tina=T; Rudy=R)
T: Thanks for killing that cockroach. You're a braver person than I.
R: Not in my book. I don't have the courage to do a bungee jump.
T: I never fear doing that, but I do fear cockroaches. They're scarier than any other bug.
R: They're not scary! I'm scared to death of heights and needles.
T: Really? What happens when you have to get a shot?
R: I become more worried and nervous than usual. Also, my heart beats really fast, and I can't breathe.
T: That doesn't sound pleasant.
R: It's not.

Populations of white-tailed deer are growing rapidly in many parts of the USA. As populations grow, food becomes a problem. Many deer die of hunger. Others grow up small and unhealthy. In search of food, hungry deer move closer to where humans live. They eat farm crops, vegetables and even trees. Also, increased numbers of deer near roads can cause traffic accidents.
Some people have the idea to catch and move them to other places. But this method is expensive and requires finding another place that can accept the deer without breaking the balance of the ecosystem.
Scientists are also working to develop chemicals to control the deer population. But this plan works for only one year at a time.
Some suggest bringing in natural enemies of deer, such as wolves, lions and bears, to areas with too many deer. But these animals could also hurt dogs, cats and even humans. Other communities have built tall walls around areas to keep out the deer. However, this is impossible for farmers.
But some people are against any kind of action. They support leaving the deer alone.
Animal populations in an area naturally go up and down over time. Doing nothing means that some deer will die of hunger or illness. But finally, the population will reach a size within the carrying capacity of the environment. So, let nature go its own way.

1. What methods do people think of to deal with the growing population of white-tailed deer?
2. Do you think "leaving the deer alone" is a good idea? Why or why not?
答案：1. People put forward these methods:
① Catch and move the deer to other suitable places that won't break the balance of the ecosystem;
② Develop special chemicals to control the deer population;
③ Bring in natural enemies of deer like wolves, lions and bears to the areas with too many deer;
④ Build tall walls around areas to keep the deer out;
⑤ Take no action, leave the deer alone and let nature adjust the deer population on its own.
2. (示例1) Yes, I think it is a good idea. Because animal populations in a certain area will naturally change over time. Finally the deer number will reach a proper size within the carrying capacity of the environment, and this way will not break the balance of the ecosystem.
(示例2) No, I don't think it is a good idea. Because too many deer will eat farm crops, cause traffic accidents and bring lots of trouble to local people's life. It is also very cruel to let a large number of deer die of hunger or illness, we can take more proper and friendly measures to control the deer population.
