Last month I was lucky eno ugh to have a cha nee to make a trip into
space with my friend Li Yanping, a astronomer. We visit the moon in our
spaceship! Before we left, Li Yanping expla ined me that the force of
gravity would cha nge three times on our journey and that the first change
would be the most powerful. Then we were off. As the rocket rose into the
air, we were pushed back into their seats because we were tryi ng to
escape the pull of the earth's gravity. It was very hard that we could not say
any thi ng to each other. Gradual the weight lesse ned and I was able to
talk to him. "Why is the spaceship not falli ng back to the earth? On the
earth if I will fall from a tree ,I will fall to the gro un d." I asked. "We are too
far from the earth now to feel it ' pull," he explained, "so we feel as if there
is no gravity at all. When we get closer to the moon, we shall feel its gravity
pull us, and it will not be as strong a pull as the earth's." I cheered up
immediately and floated weightless around in our spaceship cab in watchi
ng the earth become smaller and the moon larger.

thought he had already worked out that problem, but he could not find the papers on which he had done it. He
told Halley that the orbit of a comet had the shape of an ellipse （椭圆形）.
Then Halley set to work. He figured out （ 解决,计算出）the orbjts of some of the comets that
had bee n observed by scie ntists. He made a surpris ing discovery. The comets that had appeared in the
years 1531, 1607, and 1682 all had the same orbit. Yet their appeara nces had been 75 to 76 years apart.
This seemed very stra nge to Halley. Three differe nt comets followed the same orbit. The more Halley
