阅读理解。

　　Rockets(火箭)can fly far out into space．Rockets with men inside them have already reached the moon in the USA and Russia．Several rockets without men inside them have been sent to other worlds much farther away．On Nov．7, 2007, China’s first lunar probe, Chang’e I, successfully has completed its 1,580,000 km flying journey to the moon．

　　I am sure that you are asking ‘How does a rocket fly?’ If you want to know, get a balloon and then blow it up, until it is quite big．Do not tie up the neck of the balloon, let it go．The balloon will fly off through the air very quickly．The air inside the balloon tries to get out．It rushes out through the neck of the balloon and this pushes the balloon through the air．

　　This is how a rocket works．Of course, the rocket is made of metal．The metal must not be heavy but it must be very strong．There is gas inside the rocket, which is made very hot．When it rushes out of the end of the rocket, the rocket is pushed up into the air．The jet velocity(喷射速度)is always faster than the flying speed．

　　We’re sure that one day rockets with man may be able to go anywhere in space．

(1)

Look at the following pictures, if ‘U’ means ‘jet velocity’, ‘V’ means ‘flying speed’, which picture is RIGHT?
[　　]
A．
B．
C．
D．

(2)

The underlined word ‘it’ here refers to ________．
[　　]
A．	the rocket
B．	the metal
C．	the air
D．	the hot gas

(3)

Which of the following is NOT right?
[　　]
A．	Men have been to the moon by rocket．
B．	It’s about 1,580,000 km from the moon to the earth．
C．	A balloon can fly if the air in it goes out completely．
D．	The hot gas inside the rocket can make it fly．

答案：1．B;2．D;3．C;

　　Comets(彗星)are parts of our solar system(太阳系)．Like the planets, they go around the sun．

　　But comets are not made of solid rock like planets．A comet is a ball of dust, stones, and ice．Many people call comets dirty snowballs．

　　The “snowball” may be only a few miles across．But when the sun heats the “snowball,” much of it is changed to gases．The gases spread out and form the comet’s head, which may be thousands of miles across．

　　***

　　A comet moves fast in its trip around the sun．But when we see it, the comet does not seem to move．That’s because it is so far away．The moon moves fast, but when you look at it, you can’t see any motion．That’s because the moon is far away．

　　So comets do not rush across the sky．You cannot see any motion．But if you look night after night, you can see that a comet changes position among the stars．If you watch the moon night after night, you’ll see that it also changes position．

　　Each year astronomers discover new comets．Some of them are seen only

　　once．They make one trip around the sun and then go way out into space．The sun’s gravity(重力、引力)cannot hold them．

　　Other comets, like Halley, keep returning．They have been captured by the sun．Halley’s earliest visit was probably 3,000 years ago．It may keep returning for another 3,000 years．

　　But every time a comet goes around the sun, the comet loses part of itself．Gases and dust are pulled out of the comet．That’s why Halley is now dimmer than it used to be．Next time it visits us, in 2062, it may be even dimmer．Each visit it may get dimmer and dimmer, until it finally disappears．

(1)

What is this passage mostly about?
[　　]
A．	Comets and the sun．
B．	Why comets are like snowballs．
C．	Who discovered the first comet．
D．	Facts about comets．

(2)

According to the passage, some comets have been “captured by the sun．” What does the underlined phrase mean?
[　　]
A．	The comets are rushing into the sun．
B．	The comets have been brightened by the sun．
C．	The comets are stuck in the sun’s gravity．
D．	The comets have been burned by the sun’s heat．

(3)

How does the author help the reader understand what a comet looks like?
[　　]
A．	By telling about a famous one．
B．	By explaining how far away it is．
C．	By describing how fast it moves．
D．	By describing it as a dirty snowball．

(4)

What is the most likely reason the author wrote this passage?
[　　]
A．	To give information about comets．
B．	To tell readers about famous comets．

　　Parents and kids today dress alike, listen to the same music, and are friends．Is this a good thing? Sometimes, when Mr．Ballmer and his 16-year-old daughter, Elizabeth, listen to rock music together and talk about interests they both enjoy, such as pop culture, he remembers his more distant relationship with his parents when he was a teenager．

　　“I would never have said to my mom, ‘Hey, the latest film is really great．How do you like it?'” says Ballmer．“There was just a complete gap in taste．”

　　Film was not the only gulf．From clothing and hairstyles to activities and expectations, earlier generations of parents and children often appeared to move in their own circles．

　　Today, the generation gap(代沟)has not disappeared, but it is getting smaller in many families．Conversations on subjects such as sex and drugs would not have taken place a generation ago．Now they are common．And parent-child activities, from shopping to sports, involve a feeling of trust and friendship that can continue into adulthood．

　　No wonder greeting cards today carry the message, “To my mother, my best friend．”

　　But family experts warn that the new equality(平等)between parents and kids may also result in less respect for parents．“There's still a lot of strictness and power on the part of parents out there, but there is a change happening,” says Kerrie, a psychology professor at Lebanon Valley College．“In the middle of that change, there is a lot of confusion(困惑)among parents．”

　　Family researchers offer a variety of reasons for these changing roles and attitudes．They see the 1960s as a turning point．Great cultural changes led to more open communication that encourages everyone to have a say．

　　“My parents were on the ‘before' side of that change, but today's parents, the 40-year-olds, were on the ‘after' side,” explains Mr．Ballmer．“It's not something easily carried through by parents these days, because life is more difficult to understand or deal with, but sharing interests does make it more fun to be a parent now．”

(1)

What does the underlined word “gulf” in Paragraph 3 probably mean?
[　　]
A．	Interest．
B．	Distance．
C．	Different．
D．	Connection．

(2)

[　　]
A．	Parents share more interests with their children．
B．	Parents show less strictness to their young children．
C．	Parents help their children find interests in activities．
D．	Parents share more cultural changes with their children．

(3)

The change in today's parent-child relationship is ________．
[　　]
A．	more confusion among parents
B．	less respect for parents from children
C．	new equality between parents and children
D．	more strictness and power on the part of parents

(4)

[　　]
A．	describe the difficulties today's parents have met with
B．	discuss the development of the parent-child relationship
C．	suggest the ways to deal with the parent-child relationship
D．	compare today's parent-child relationship with that in the past
