When discussing the causes of animal endangerment, it is important to understand that individual species are not the only factors involved in this difficult situation.Endangerment is a broad 1 , one that involves the habitats(栖息地)and environments where species live and interact with one another.Although some measures are being taken to help specific cases of endangerment, the universal problem cannot be solved until humans 2 the natural environments where endangered species live.There are many reasons why a particular species may become endangered, but habitat destruction is on top.
Our planet is continually changing, causing habitats to be altered and modified.Natural changes tend to occur at a 3 pace, usually causing only a slight 4 on individual species.However, when changes occur at a fast pace, there is little or no time for individual species to 5 and adjust to new circumstances.This can create disastrous results, and for this reason, rapid habitat loss is the primary cause of species endangerment. The strongest 6 in rapid habitat loss are human beings. Nearly every region of the earth has been affected by human activity, particularly during this past century.The loss of microbes(微生物)in soils that 7 supported tropical forests, the 8 of fish and various aquatic species in polluted habitats, and changes in global climate brought about by the 9 of greenhouse gases are all results of human activity.
It can be difficult for an individual to 10 the effects that humans have had on specific species.It is hard to identify or predict human effects on individual species and habitats, especially during a human lifetime.But it is quite 11 that human activity has greatly 12 to species endangerment. 13 , although tropical forests may look as though they are thick and healthy, they are 14 highly susceptible(易受影响的)to destruction.This is because the soils in which they grow 15 nutrients. It may take centuries to re-grow a forest that was cut down by humans or destroyed by fire, and many of the world’s severely threatened animals and plants live in these forests. If the current rate of forest loss continues, huge quantities of plant and animal species will disappear.

1._________
Television has probably been the most powerful medium in shaping the new community. The electronic community gives us our mutual friends, our significant events and our daily chats. The “produced” relationships of television families become our models for intimacy. We know media stars better than we know our neighbors. Most of us can discuss their lives better than we can discuss those of our relatives. We think a man who plays a doctor on TV actually know something about medicine
2._________
TV isolates people in their spare time. People spend more time watching music videos but less time making music with each other. People in small town now watch international cable networks instead of driving to their neighbor’s house for cards. Women watch soaps instead of attending church circles or book clubs. When company comes, the kids are sent to the TV room with videos.
3._________
Parent are not the main influence in the lives of their children. Some of the first voices children hear are from the television, the first street they know is Sesame Street. A child playing Nintendo is learning different lessons than a child playing along a creek or playing dominoes with a grandfather.
4._________
The time devoted to violence on TV in no way reflects its importance in real life. In real life, most of us exercise, work, visit our friends, read, cook and eat and shop. Few of us spend any significant amount of our time solving murders or fleeing psychotic killers. On television there are many more detective and murderers than exist in the real world. A rule of thumb about violence is “If it bleeds, it leads.” Violence captures viewers’ attention. Our programs have become increasing violent.
5._________
Some might say that there is nothing new under the sun. Of course, in a narrow sense, they are correct. There have always been murderers, and stories about violence have been the theme of literature and song. However, things are different now. Children are exposed to hundreds of examples of violence every day. The frequency and intensity of these images is unprecedented in the history of humanity. We have clear records that this exposure makes it more likely that children will be violent and increase their fear levels about potential violence.
There are many American expressions about insects--- like bees, for example. Bees are known as very hard workers. They appear to be busy, moving around their homes, or hives (蜂窝). So you might say you were as busy as a bee if you spent your weekend cleaning your house. In fact, you might say your house was a beehive of activity if your whole family was helping you clean. You also might say you made a beeline for something if you went there right away. When we go to see a movie, my friend always makes a beeline for the place where they sell popcorn (爆米花) .
Here is an expression about bees that is not used much any more, but we like it anyway. We think it was first used in the 1920s. If something was the best of its kind, you might say it was the bee’s knees. Now, we admit that we do not know how this expression developed. In fact, we do not even know if bees have knees!
If your friend cannot stop talking about something because she thinks it is important, you might say she has a bee in her bonnet (女帽). If someone asks you a personal question, you might say “that is none of your beeswax”. This means none of your business.
Speaking of personal questions, there is an expression when their children ask, “Where do babies come from?” Parents who discuss sex and reproduction (生殖) say this is talking about the birds and bees.
Butterflies are beautiful insects, but you would not want to have butterflies in your stomach. That means to be nervous about having to do something, like speaking in front of a crowd. You would also not want to have ants in your trousers. That is, to be unable to sit still.
