Mystery creates wonder and wonder is the basis of man's desire to understand.(神秘感激发好奇心，而好奇心则是人们探索未知事物的前提。) —Neil Armstrong(尼尔·阿姆斯特朗) 单元话题导入 [品读话题短文] Speaking of① space，I couldn't help but think② it was the silence and mystery③.The teacher told me that human beings are exploring the mysterious space.There is only silence and space on many planets，asteroids④.I remember when I was young，especially the kindergarten teacher often told something about the space.For example，“Some of those asteroids around the Sun，when they pass the Earth，will be attracted to the Earth's gravity⑤”．If one day，I am like Uncle Yang Liwei aboard the same space，I will strive to explore space to find all the answers; if I come to space，I will go to see aliens and shake hands with them，talk to them，or make friends with them; if I come to space，I will certainly protect some planets and keep it quiet forever.Aah! I must study hard from an early age and grow up to build a better motherland，to build a unique⑥ spaceship in the world，to take a self­built spaceship，and to seek answers to some questions about space. Leroy Chiao，54，an American retired astronaut after four flights，describes what happens even before you float⑦ out of your seat.“Your inner ear thinks you're falling.Meanwhile your eyes are telling you you're standing straight.That can be annoying—that's why some people feel sick.”Within a couple of days—truly terrible days for some—astronauts' brains learn to ignore the panicky⑧ signals from the inner ear，and space sickness disappears.
