There are some objects in the sky that move so quickly that sometimes you only see them out of the corner of your eye. These are some of the huge number of bits of rock and dust that are floating around in space, called meteoroids. Normally, we cannot see them at all, but if they travel too close to the Earth, they get caught by the pull of the Earth, and begin to fall towards us. They fall faster and faster, until they hit our atmosphere(大气层), by which time they are going so fast that they begin to burn up, and all that you see is a flash of light that moves very quickly across the sky and disappears. These shooting stars, or meteors as they are properly called, are quite common, and sometimes you may see several in a night.
Most meteoroids are very small bits indeed, and they burn up long before they get to the Earth. However, a very few do manage to get all the way through the atmosphere, and actually fall to the ground. Usually they do not do much damage, although this is not always the case.
Meteoroids that actually manage to reach the Earth are called
meteorites
. Most countries have places where meteorites have struck the Earth. Some of these places are very large indeed and are tourist attractions.
What happens to most meteoroids coming into the atmosphere?
选项
A、They burn up.
B、They fall to earth.
C、They explode.
D、The float in the air.
答案
A
解析
推理题。题干意为“大部分流星在穿过大气层时会发生什么?”由文章第一段可知,那时它们的速度如此之快以至于它们开始燃烧,你所能看到的只是一道光划过天空,然后消失不见。由此推出,流星穿过大气层时会燃烧,故A正确。
