For thousands of millions of years the moon has been going round the earth. At that time, the moon was the 　36 satellite(卫星)of the earth. Today, 　37 , the earth has many other satellites. All of them are 38 by man. These man-made satellites are very much smaller than the moon. However, some of them will still be going 39 the earth thousands of years from now.

Man-made satellites don’t 40 because they are going too fast to do so. As they speed along, they 41 to go straight off into space. They 42 out of the earth, or its gravity, which 43 them from doing this. As a result, they travel in an orbit(轨道)round the earth.

If a man-made satellite travels about at a certain height, it can keep going 44 round the earth, just like the moon. This is 45 it is above the atmosphere(大气), and there is nothing to 46 it down. If it travels 47 than that, it will be slowed down so much that it will 48 the earth.

Men have 49 spaceships to the moon and to the two 50 planets Mars(火星) and Venus(金星). By putting a camera on 51 the spaceship to the moon, men have been able to 52 photographs of the other side of the moon. This side is always 53 from us as the moon 54 the earth. The 55 were later transmitted by radio to the earth. They showed that the other side of the moon is very much the same as the side that turns towards us.

Cancer is feared by everyone. And there is more and more fear about cancer. Not the disease itself — there is no such thing as a high incidence rates(发病率) of cancer. Except for lung cancer, mostly caused by cigarette smoking, the incidence rates are not on the rise. However, some kinds of cancer are decreasing. But the fear of cancer is catching, and the country stands at risk of an anxiety. The earth itself is coming to seem like a huge carcinogen(致癌物). The ordinary, more or less, scientific statement that something between 80 and 90 percent of all cancers are due to things in the environment is taken to mean that none of us will be safe until the whole environment is “cleaned up.” This is not at all the meaning.
The 80-percent calculation is based on the unthinkable differences in the incidence of cancer in various societies around the world — for example, the high incidence of liver cancer in Africa and the Far East, stomach cancer in Japan, breast cancer in Western Europe and North America, and the relatively low figures for breast cancer in Japan and parts of Africa and for liver cancer in America. These data show there may be specific environmental influences, but largely based on personal life-style, which determines the incidence of various forms of cancer in different communities — that is all the data suggest. The overall incidence of cancer, counting up all the cases, is probable roughly the same everywhere.
【小题1】According to the passage, the incidence of cancer is generally believed _____.

_____ was known to all , Willian had broken his promise ______ he would give us a rise.

War, money and power are a few things that countries and people are concerned about. __1__ I agree that those things are important, I believe that everyone should start to __2__ more on a growing problem—global warming.

Global warming will not only __3__ our country and our generation, but also the entire __4__ and future generations. It is __5__ because the weather has been a lot warmer over the past few years, which __6__ the melting(融化) of the ice in the Antarctic. This will soon cause water levels to __7__ and flood parts of the world.

Many people ignore this problem because they feel __8__ they can't do anything about it and have more __9__ things to worry about. If we all __10__ so, then our ozone layer(臭氧层) will be __11__ and the planet will no longer be able to make life continue to exist. We should do our best to limit the use of our planet's __12__ resources(资源) and keep our air clean. __13__， future generations will suffer from our __14__.

Some might feel that they can't stop global warming from __15__. But if every single person does his or her part in keeping the air clean, then it will become a __16__ effort. Sure, there are some things that cause pollution and that we won't be able to __17__ change. This may include cars burning oil, but we can __18__ adjust some of these things. People can start carpooling, taking the bus, riding their bikes, or __19__ just walking.

If everyone takes __20__ now, I believe we can start seeing remarkable results within a few years.
