Scientists would like to place a huge mirror in space above the earth. It might be sixty miles wide. It would be used to catch the rays (光線) of the sun. It would direct the sun’s rays upon the earth as a child might do to make sunlight dance on the wall with a hand mirror.

Why do they want to do this? The sun’s rays could be helpful in many ways. They could light up cities by night. The warm rays could stop frosts (霜凍) which might come at night and hurt fruit crops. They could melt (融化) dangerous icebergs in the ocean. Perhaps they could change cloud movements and bring rain where it is needed.

1.The huge mirror would ______.

A．stand 60 miles in height (高度)             B．be 60 miles from side to side

C．cover 60 miles of the earth                D．be 60 miles above the earth

2.The mirror would be used to ______.

A．reflect (反射) sunlight                    B．a(chǎn)bsorb (吸收) sunlight

C．see what the earth looks like               D．see how clouds move

3.The strong light from the mirror could possibly ______.

A．hurt fruit crops                         B．set fire to cities

C．bring longer daytime                     D．shine through walls

4.The huge mirror is ______.

A．something in a story                     B．a(chǎn)lready made

C．just an idea                            D．to be made soon

　　Man always wanted to fly. For hundreds of years they watched birds flying and wished that they could fly, too. Birds fly very easily. They spread(展開) their wings(翅膀) and float (漂浮) on the air. The air keeps them up for many hours.“If birds and kites can stay up in the air, perhaps we can, too.”they thought.

　　At first they made wings like birds. Then they jumped off high buildings in order to fly. Many men did this but they all failed. After many failures (失敗) they stopped trying to fly with wings. Then two brothers tried another way. They tried balloons (氣球).“Hot air is lighter than cold air,”they said, “That is why hot air goes upwards. If we fill a balloon with hot air, it will go upwards.”

　　After many experiments, they made two men go up in a balloon full of hot air. A great crowd of people watched. The balloon rose to a height (高度) of 900 metres. The wind blew it along for nine kilometers. Then it came gently back to earth. For the first time man traveled through the air!

[　　]
