Forests have always been useful and important to man who makes use of them in many ways. Every day trees are serving man everywhere. Trees supply man with fruits and building materials in the form of wood. Without trees it would be impossible to build houses, boats, bridges and so on. Furniture such as desks, chairs and beds is made of wood. Trees can stop man from terrible heat. They're also useful in preventing good and rich top soil from being washed away during heavy rains.

　　If there were no trees, heavy rains would wash away the rich top soil that is so important to plants. The result is that the land will become a desert. There are plenty of desert areas in the world. A long time ago these desert areas used to be very rich areas, but man in the past had no enough knowledge about science of nature, they cut down too many trees in the area where they lived and never planted new ones. By and by the rich top soil was blown and washed away by strong winds and heavy rains. In the end the rich land changed into useless deserts where nothing could grow.

According to the passage, ______.

　　　　A. a long time ago, man didn't know how to make use of wood

　　　　B. trees are not as useful as they were in the past

　　　　C. trees were more found in the past than they are today

　　　　D. people have always found trees useful

　　If there were no trees, ______.

　　　　A. the land would become better　　　　B. heavy rains would be very clean

　　　　C. the rich soil couldn't be kept　　　　 D. there wouldn't be any plants

　From the passage, we know that man must ______.

　　　　A. do nothing to keep the balance（平衡）of nature

　　　　B. take his best to keep the balance of nature

　　　　C. try his best to keep the balance of nature

　　　　D. do his best to stop the balance of nature

A three-year independent investigation into the September 11, 2001 attack on the Pentagon has yielded new eyewitness evidence which, according to the Southern California-based researchers who conducted the investigation conclusively (and unfortunately), establishes as a historical fact that the violence which took place in Arlington that day was not the result of a surprise attack by suicide hijackers, but rather a military black operation involving a carefully planned and skillfully executed deception."

A CNN Reporter at the scene states that there is no evidence that a 757 hit the Pentagon.

　  What hit the Pentagon? A Boeing 757 loaded with passengers and fuel right? Who was on Flight 757? According to the Flight Information there were No Arabs on it. That makes me wonder if Flight 757 actually existed at all.

　　From the pictures and the videos, people can find that there are several doubtful points that need to be taken into consideration, for example the marker line on the grass in the satellite and ground pictures, the different colors of the smoke, the hole which the plane impacted, and the standing pylons (架线塔).

　　Also, from the comparison of the different pictures, people can find some other strange points. For example, the gear (齿轮) is not the matching one. The wreckage of the plane is not the one from the American Airlines. The glass on the pavement of the pole is another doubtful point. The last thing that need considering is about the collapse. One of the gif video shows the plane impacting the Pentagon. The only problem with this video footage is that it has been altered (改变) and can not be fully trusted.

　　These crash photos and videos shown here clearly have been doctored (篡改) and don't even match the physics of what happened. So where is the real video? It leaves me many questions. Is this a missile? It is a real enigma.

　　Good afternoon, and welcome to England. We hope that your visit here will be a pleasant one. Today, I would like to draw your attention to a few of our laws.

　　The first one is about drinking. Now, you may not buy alcohol in this country if you are under 18 years of age, nor may your friends buy it for you.

　　Secondly, noise. Enjoy yourselves by all means, but please don't make unnecessary noise, particularly at night. We ask you to respect other people who may wish to be quiet.

　　Thirdly, crossing the road. Be careful. The traffic moves on the left side of the road in this country. Use pedestrian crossing and do not take any chances when crossing the road. My next point is about litter（throwing away waste material in a public place）. It is an offence to drop litter in the street.

　　When you have something to throw away, please put it in your pocket and take it home, or put it in a litter bin. Finally, as regards smoking, it is against the law to buy cigarettes or tobacco if you are under 16 years of age.

　　I'd like to finish by saying that if you require any sort of help or assistance, you should contact your local police station, who will be pleased to help you.

　　Now, are there any questions?

The main purpose of this speech would be to ______.

　　　　A. prepare people for international travel

　　　　B. you may not buy cigarettes or tobacco unless you are above 16 years of age
