10、tion and must overcome (克服) if we are to get anywhere in space, or off the ground at all.Take the throwing of a ball as an example. The harder the ball is thrown, the faster and higher it will go. What is the secret? Its speed. If we could throw the ball hard enough it would go up and up forever and

11、 never come down. The speed at which it would have to be thrown do this is known as escape speed. Of course, we cannot throw a ball hard enough because the speed required to escape completely from the Earths gravity is seven miles per second, or over twenty-five thousand miles per hour.Once a spacec

12、raft has reached escape speed, no further power is needed. A rocket aimed at the Moon, for instance, will “coast“ (滑行) the rest of the way because the Earths gravity cannot then pull it back, and there is no air resistance (阻力) in space to slow it down. This “coasting“ is known as “free fall“ Free f

13、all is an important feature (特点) of space travel: it would be impossible to carry enough fuel to provide powered flight all the time.（分数：20.00）(1).As there is always the Earths gravitational (地心力的) pull, people _.

16、e time? A. Few spacecraft complete their flight operations. B. No further power is needed after the escape speed is reached. C. The spacecraft will be attracted by the Moon. D. “Free fall“ takes the place of the Earths gravitational pull.（分数：5.00）A.B.C.D.Trees are useful to man in three important wa

17、ys. They provide him with wood; they give him shade; they help prevent drought (干旱) and floods.

18、h to gain itself an empire (帝国). It gained the empire; however, its soil became poor. When the empire fell to pieces, the country found itself faced by floods and starvation.Even where a government realizes the importance of a plentiful supply of trees, it is difficult for it to persuade villagers t

But during previous (以前的) attempts, the treatment caused deadly chemical changes in the blood. Th

27、e BioLogic-HT System prevents those changes from happening, allowing the heat to kill viruses with few ill side effects.Tests of BioLogic-HT treatment began on 36 patients earlier this year.
