People once thought that the Earth was flat and that you could fall __1__ the edge. Most of us now think of the planet as a sphere. It is quite useful to think of the Earth and its atmosphere as being rather like an onion----that is, a ball made up of layers,__2__, unlike an onion, each layer is made of a different material.
One of the stories created by the writer Jules Verne described a journey to the center of the Earth, but at the Earth's center it __3__ rather uncomfortable because the inner core of our planet is thought to be made of an alloy(合金) of nickel and iron at a pressure some four million times greater than that which we experience at the surface. __4__ this inner core is an outer core which seems to be liquid and is made of nickel and iron together with a lighter element such __5__ silicon or sulphur.
It is very difficult to discover what it is like within the Earth. Information has been collected __6__ the study of earthquake waves, which react differently in rocks of different densities and different __7__ of solidity. Volcanoes also provide evidence as they throw up to the surface materials from great depths. There is one other __8__ of information----meteorites which fall from space and are thought to represent the composition of the Universe as a whole.
Outside the core is the mantle. The evidence we have from the way in which earthquake waves pass __9__ the mantle suggests that it is solid but it is likely that the upper part is more plastic in consistency. The composition of the mantle seems to be similar __10__ that of a rock found at the Earth's surface called peridotite(橄榄岩) which contains iron, magnesium(镁), silicon and oxygen.
Finally, surrounding the mantle, the Earth has a very thin skin known as the crust which is probably nowhere more than 50 kilometers (30 miles) thick. The crust is at its thickest under the world's mountain belts.

The World Health Organization says as many as 10 million persons worldwide may have the virus(病毒) that causes AIDS. Experts believe about 350 thousand persons have the disease. And one million more may get it in the next five years. In the United States, about 50,000 persons have died with AIDS. The country's top medical official says more than 90 percent of all Americans who had the AIDS virus five years ago are dead.
There is no cure for AIDS and no vaccine medicine to prevent it. However, researchers know much more about AIDS than they did just a few years ago. We now know that AIDS is caused by a virus. The virus invades healthy cells including white blood cells that are part of our defense system against disease. It takes control of the healthy cell's genetic material and forces the cell to make a copy of the virus. The cell then dies And the viral particles move
on to invade and kill more healthy cells.
The AIDS virus is carried in a person's body fluids. The virus can be passed sexually or by sharing instruments used to take intravenous(静脉内的) drugs. It also can be passed in blood products or from a pregnant woman with AIDS to her developing baby.
Many stories about the spread of AIDS are false. You cannot get AIDS by working or attending school with someone who has the disease. You can not get it by touching, drinking glasses or other objects used by such persons. Experts say no one has gotten AIDS by living with, caring for or touching an AIDS patient.
There are several warning signs of an AIDS infection. They include always feeling tired, unexplained weight loss and uncontrolled expulsion of body wastes. Other warnings are the appearance of white areas on the mouth ,dark red areas of skin that do not disappear and a higher than normal body temperature.
