Rockets in the Sky
If someone asked you,"What color is the sky?"I expect that you would answer,"Blue."I am afraid that you would be wrong.The sky has no color.When we see blue,we are looking at blue sunlight.The sunlight is shining on little bits of dust in the air.
We know that there is air all around the world.We could not breathe without air.Airplanes could not fly without air.They need air to lift their wings.Airplanes cannot fly very high because as they go higher the air gets thinner.If we go far enough away from the earth,we find there is no air.
What is the sky?The sky is space.In this space there is nothing except the sun,the moon and all the stars. Scientists have always wanted to know more about the other worlds in the space.They have looked at them through telescopes and in this way they have found out a great deal.The moon is about 384 ,000 kilometers away from the earth.An airplane cann't fly to the moon but there is a thing that can fly even when there is no air. This is rocket.
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 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.It does not need wings like an airplane.
This is how a rocket works.It is not made of rubber（橡胶）like a balloon,of course.It 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.
Rockets can fly far out into space.Rockets with men inside them have already reached the moon.Several rockets,without men inside them,have been sent to other worlds much farther away.One day rockets may be able to go anywhere in the space.

What color is the sky?
A:It is blue.
B:It is white.
C:It is grey.
D:It has no color.

答案：D

解析：

根据第一段第四句可知，天空没有颜色。
根据第二段第五句“Airplanes cannot fly very high because as they go higher the air gets thinner.”可知，由于位置越高，空气越稀薄，飞机飞不了太高。
根据第五段可知，火箭飞行的原理与没扎口的膨胀的气球相似。
根据第六段最后一句“When it rushes out of the end of the rocket , the rocket is pushed upinto the air.”可知，火箭是由热气流高速向后喷出所产生的反作用力来推动的，而不是由内部燃烧的气体推动的。
根据第六段最后一句可知，当热气从火箭尾部冲出时，火箭被送人空中。C项中的“itsbottom”是第六段最后一句中的“the end of the rocket”的同义转换。

第4题：

We can make mistakes at any age.Some mistakes we make are about money.But most mistakes?are about people."Did Jerry really care when I broke up with Helen?When I got that great job,did Jim really feel good about it,as a friend?Or did he envy my luck?"When we look back,doubts?like these can make us feel bad.But when we look back,it′s too late.
Why do we go wrong about our friends or our enemies?Sometimes what people say hides their?real meaning.And if we don′t really listen closely we miss the feeling behind the words.Suppose?someone tells you,"You′re a lucky dog."That′s being friendly.But"lucky dog"?There′s a bit?of envy in those words.Maybe he doesn′t see it himself.But bringing in the"dog"puts you down a?little.What he may be saying is that he doesn′t think you deserve your luck.
"Just think of all the things you have to be thankful for"is another noise that says one thing and?means another.It could mean that the speaker is trying to get you to see your problem as part of your life as a whole.But is be?Wrapped up in this phrase is the thought that your problem isn′t important.It′s telling you to think of all the starving people in the world when you haven′t got a date for Saturday night.How can you tell the real meaning behind someone′s words?One way is to take a good look at?the person talking.Do his words fit the way he looks?Does what he says agree with the tone of?voice?His posture?The look in his eyes?Stop and think.The minute you spend thinking about the?real meaning of what people say to you may save another mistake.

According to the author′,the reason why we go wrong about our friends is that

A.we fail to listen carefully when they talk
B.people tend to be annoyed when we check what they say
C.people usually state one thing but mean another
D.we tend to doubt What.our friends say

答案：C

解析：

【考情点拨】推理判断题。【应试指导】由第二段第二句及第三段首句可知，有时人们所说的话掩饰了其真实含义，而且言不由衷。故选C。

Things We Know about TV

We keep reading that TV is bad for you.If this is true,how come the current generation of TV-addicted kids is much smarter than we are?In my home,the only people who can work the remote control are the children.
Perhaps TV does educate you.For example,you learn a useful medical fact:A person who has been shot always has time to speak an incomplete sentence before he dies.“The killer was…” (dies).
But I guess the biggest things we learn from TV can be regarded as"Life Skills".Bad things only happen on dark and stormy nights.Emotional breakdowns cause people to wander in the heavy rain without umbrellas.And contrary to what scientists say,the crack（霹雳）of lightning and the accompanying flash happen at exactly the same time,wherever you are.
Making use of what we learn from TV can improve our security.Consider these truths.If you are ever attacked by 20 bad guys,don't worry about being outnumbered.The criminals will hang back and take turns to approach you in ones and twos just so you can conveniently defeat them all.
TV also teaches us important information about escaping from danger. Watch and learn.If anyone is running after you down a passage,you will find that boxes have been conveniently placed near all the walls you need to jump over. If you are tall and handsome,you can run from any number of armed criminals,and every shot will miss you.
Be warned, however. If your name card says "henchman"（帮凶）and you are part of a group of plain-looking people trying' to catch a handsome individual,a single shot will kill you.
TV even teaches us about TV.Whenever anyone turns on a TV,it shows a news flash about someone they know. They then turn the box off immediately after that news item.

We can learn from Paragraph 3 that in the real world__________.
A:bad things cause people to break down in the rain
B:bad things never happen on dark and stormy nights
C:people with emotional problems like to walk in the rain without umbrellas
D:the crack of lightning and the flash don't harmen at the same time

答案：D

解析：

细节题。第二段第二句：你学到了一个有用的医学事实：被枪击的人总是在他死前有时间说出一句不完整的话。这句话明显是体现了幽默，有着讽刺的意味。B选项 sympathy“同情”、C选项deep concern“非常关心”、D选项medical knowledge“医学知识”都是错误的。
细节题。第三段很多是电视中的情景，根据作者幽默讽刺的语气可知现实生活不一定是这样的。最后一句指出，闪电的霹雳声与相伴的闪其实不是同时发生的。
细节题。最后一段可知：任何时候一个人打开电视，它就会显示一则关于他们知道的人的新闻快讯。
推断题。通篇阅读后可知，作者以幽默、讽刺的手法描写了电视，可以得知，作者对电视持消极的态度。A选项“积极的”、B选项“轻松的”、D选项“漠不关心的”都是错误的。
主旨题。A、B、C都和作者态度相反，只有D选项是正确的，本文大意是电视上演的与现实生活是不同的。

A

who are at the bottom of the society

B

who are higher up in their social status

C

问答题

You can’t know your planet unless you know something about science and technology. School science courses, I remember, concentrated on the unimportant parts of science, leaving the major insights almost untouched. The great discoveries in modern science are also great discoveries of the human spirit. For example, Copernicus showed that --far from being the center of the universe, about which the Sun, the Moon, the planets, and the stars revolved in clockwise homage--the Earth is just one of many small worlds. This is a deflation of our pretensions, to be sure, but it is also the opening up to our view of a vast and awesome universe. Every high school graduate should have some idea of the insights of Copernicus, Newton, Darwin, Freud, and Einstein. (Einstein’s special theory of relativity, far from being obscure and exceptionally difficult, can be understood in its basics with no more than first-year algebra, and the notion of a rowboat in a river going upstream and downstream.)

正确答案：除非你对科学技术有所了解,否则你不可能认知你所生存的星球。我现在还记得学校的理科课程专讲科学的次要部分,相反对科学的深层含义却几乎只字不提。现代科学的伟大发现同样也是对人类精神的伟大发现。例如,哥白尼表明地球根本不是什么太阳、月亮以及其他行星和星球顺时针绕其运转的宇宙中心,而只是许多小小世界中的一个而已。当然,他的学说挫败了人类自命不凡的傲气,但同时也开阔了我们的视野,使我们看到一个浩瀚无垠、令人敬畏的宇宙。每位中学毕业生都应当对哥白尼、牛顿、达尔文、弗洛伊德和爱因斯坦的深刻思想有所了解。(爱因斯坦的狭义相对论根本算不上晦涩,也算不上特别难懂,只要有一年级的代数知识和在河中划艇逆流而上和顺流而下的概念,其基本原理是完全可以弄懂的。)

第13题：

(阅读理解题)Advertisements make us want too much, so we get the idea that the only purpose of advertising is to sell goods.But it is not completely right.Advertisement has another equally important function—to inform.A great deal of the knowledge we have about household goods derives largely from the advertisements we read.Advertisements introduce us to new products or remind us of the existence of ones we already know about.Supposing you wanted to buy a washer, it is more than likely you would obtain details regarding performance, price, etc., from an advertisement.Lots of people pretend that they never read advertisements, but this claim may be seriously doubted.It is hardly possible not to read advertisements these days.And what fun they often are, too! Just think what a railway station or a newspaper would be like without advertisements.Would you enjoy gazing at a blank wall or reading railway byelaws while waiting for a train? Would you like to read only closely printed columns of news in your daily paper? A cheerful, witty advertisement makes such a difference to a drab wall or a newspaper full of bad news.We must not forget that advertising makes a positive contribution to our pockets.Newspapers, commercial radio and television companies could not subsist without this source of revenue.The fact that we pay so little for our daily paper, or can enjoy so many broadcast programs is due entirely to the money spent by advertisers.Just think what a newspaper would cost if we had to pay its full price! Another thing we mustn’t forget is the ‘small ads.’ in virtually every newspaper and magazine.What a tremendously useful service they perform. for the community! Just about anything can be accomplished through these columns.For instance, you can find a job; buy or sell a house; announce a birth, marriage, or death in these small ads.

(1).What will you possibly want to know from a washer advertisement?

A、some details

B、how much it will cost

C、its functions

D、all of the above.

(2).What is the author’s attitude towards most people’s claim that they never read advertisements?

A、doubt

B、agreement

C、acceptance

D、in favor of

(3).According to the text, which of the following statements is true?

A、only TV commercials are useful in daily life

B、advertisements help to change our life

C、advertisements should be serious

D、advertisements make us spend more money on newspaper, magazines and broadcast programs

(4).In the passage, the author is focusing on ____________.

A、how people buy things through advertisements

B、the useful service of advertisements to the community

C、how advertisers spend their money

D、the advantages and disadvantages of advertisements

Passage 2Americans don't like to lose wars. Of course,a lot depends on how you define just what a war is. There are shooting wars-the kind that test patriotism and courage-and those are the kind at which the U.S. excels. But other struggles test those qualities too. What else was the Great Depression or the space race or the construction of the railroads? If American indulge in a bit of flag-when the job is done, they earned it.Now there is a similar challenge-global warming. The steady deterioration of the very climate of this very planet is becoming a war of the first order, and by any measure, the U.S. is losing. Indeed, if America is fighting at all, it's fighting on the wrong side. The U.S. produces nearly a quarter of the world's greenhouse gases each year and has stubbornly made it clear that it doesn't intend to do a whole lot about it. Although 174 nations approved the admittedly flawed Kyoto accords to reduce carbon levels, the U.S. walked away from them. There are vague promises of manufacturing fuel from herbs or powering cars with hydrogen. But for a country that tightly citespatriotism as one of its core values, the U.S. is taking a pass on what might be the most patriotic struggle of all. It's hard to imagine a bigger fight than one for the survival of a country's coasts and farms, the health of its people and stability of its economy.The rub is, if the vast majority of people increasingly agree that climate change is a global emergency, there's far less agreement on how to fix it. Industry offers its plans, which too often would fix little. Environmentalists offer theirs, which too often amount to native wish lists that could weaken America's growth. But let's assume that those interested parties and others will always bent the table and will always demand that their voices be heard and that their needs be addressed. What would an aggressive, ambitious, effective plan look like-one that would leave the U.S. both environmentally safe and economically sound?Halting climate change will be far harder. One of the more conservative plans for addressing the problem calls for a reduction of 25 billion tons of carbon emissions over the next 52 years. And yet by devising a consistent strategy that mixes short-time profit with long-range objective and blends pragmatism with ambition, the U.S. can, without major damage to the economy, help halt the worst effects of climate change and ensure the survival of its way of life for future generations. Money will do some of the work, but what's needed most is will.I'm not saying the challenge isn't almost overwhelming,says Fred Krupp.But this is America, and America has risen to these challenges before.From the last sentence of Paragraph 2，we may learn that the survival of a country's coasts and farms，the health of its people and the stability of its economy is________.

A

of utmost importance

B

a fight no one can win

C

beyond people's imagination

D

a less significant issue
