     About the year 1900, a small, dark-haired boy named Charlie Chaplin was often seen waiting outside the back

entrances of London theatres. He looked thin and hungry. He was hoping to get work in show business. He could

sing and dance,and above all,he knew how to make people laugh. But he couldn't get work and therefore wandered

about the city streets. Sometimes he was sent away to homes for children who had no parents.

     But twenty years later this same Chaplin became the greatest, best-known, and best-loved comedian in the world.

Any regular visitor to the cinema must have seen some of Charlie Chaplin's films. People everywhere have laughed

at them until tears have run down their faces. Even people who don't understand English can enjoy Chaplin's films

because they are mostly silent. It isn't what he says that makes us laugh. It depends on little actions which mean the

same thing to people all over the world. Acting out, without words, the common human play an important part in the

dances and plays of many countries. It's a kind of world language.

     Chaplin lived most of his life in America and died in Switzerland on Christmas Day in 1977 at the age of eighty-eight.

There was sadness all over the world at the news of his death.

1. Why was young Chaplin waiting outside the back entrance of the theatre?

A. Because he wanted to enjoy a play in the theatre.

B. Because he had no money to buy tickets.

C. Because he liked to act a part in a play and thus made a living.

D. Because he wanted to become a man of business.

2. Chaplin's comedies didn't almost depend on         .

阅读以下文字，完成以下问题。
你知道吗光辉灿烂的太阳也在不断的向四面吹着“风”。最直接的证据就是彗星的尾巴，总是背着太阳。开始有人推测是由于太阳光的光压所造成的，因为物理学家发现：照射在物体上的光，能对物体产生一定的压力，这叫光压。那么太阳光的光压有多大经过仔细测量，在距离太阳1个天文单位的位置(即地球——太阳距离)，在1平方米的面积上，太阳光可产生 0.001克的压力。
后来对于太阳的研究不断深入，许多科学家认为：除了太阳光压以外，太阳上还在持续“吹风”，这样才将轻薄的彗尾“吹”向背离太阳的方向。人们还进一步推测：太阳风是从太阳上辐射出的大量带电粒子。
科学家利用人造卫星和宇宙飞船等所作的观测，完全证实了太阳风的存在。这是来自太阳的高温、高速，低密度的带电粒子流，持续不断“吹”向四面八方。“太阳风”从遥远的太阳上面吹来，经过一亿五千万千米的距离，到达地球时速度还高达450千米/秒左右，因此“太阳风”的能量可不能低估啊!
科学家设计出“太阳帆宇航器”，专门利用太阳光压和太阳风作为动力，使宇航器驶向茫茫宇宙。近年来，随着微电子和材料科学的飞速发展，一直探索更快、更好、更便宜的空间飞行方式的美国宇航部门，重将目光投向了太阳帆计划。美国航空航天局的科学家们称，第一艘飞往太阳系边缘的“太阳光帆航天器”可在10年内发射。预计在近期升空的俄罗斯宇宙1号飞船，将首次使用太阳帆，将飞船送人太空。
科学家认为，如果开发出边长200米、密度为每平米1至5克的帆，许多远距离探测将成为可能。如果帆的密度降到每平米1.5克，太阳光和太阳风在帆上产生的推力即可与太阳的引力相平衡。当航天器到达太阳极地上方时，即可长久地在此观察太阳的活动，这是迄今为止人类航天器从未到达的地点。如果将多个位于不同高度的航天器拍摄的太阳图像[ ]起来，就可以获得太阳的立体图形。
既然“太阳风”是一股高能带电粒子流，那么对于地球磁场的扰动不可忽视，因此科学家一直不断研究观察“太阳风”的动态。而当太阳活动高峰时，“太阳风”的强度和速度会大大增加，这就是我们说的“太阳风暴”。

根据文章下列说法不正确的一项是( )。

A．彗星的尾巴不是太阳光压造成的

B．太阳风的速度随着距离的拉长而减弱

C．研究太阳风活动有利于保护地球

D．太阳帆每平米密度越小，它飞行的距离越远
