If you watch the sky about an hour after the sun goes down, you
may see some “moving stars”. But they're not real stars. They
are manmade satellites. And the biggest of all is the International
Space Station (ISS 国际空间站).
From now until July is the best season to watch the ISS flying over
the earth, and people can see it just with their eyes. The ISS is the
biggest manmade satellite because scientists want to live on it. They
think that the best way to learn more about space is to live there.
When the space station is finished, it will be like a city in space.
People will stay and study there with many of the things they have
at home. Laboratories, living rooms and power stations are being built.
The ISS is the most ambitious and expensive space program
ever. Billions of dollars are being spent on it every year. Scientists
hope that the ISS will be a steppingstone for future space exploration.
“The ISS will help us better understand the human body, explore space
and study the earth. It can help us make life on the earth better,”
said Kathryn Clark, an ISS scientist.
China is not an ISS country, but it has helped with some of the
experiments. China sent some rice up to the ISS to find out what
space would do to it.
The ISS is not finished yet. More than 100 parts need to be put on.
Scientists hope it will be finished as soon as possible. After it's
finished, more than 90% of the world's population will be able to see
the Space Station. So keep looking up, and maybe you'll see it get bigger.

HOW LIFE BEGAN ON THE EARTH
No one knows exactly how the earth began,
as it happened so long ago①. However,
according to② a widely accepted③ theory④ ,
the universe began with⑤ a “Big Bang⑥” that
threw matter in all directions⑦. After that,
atoms⑧ began to form and combine to create
stars and other bodies.
For several billion⑨ years after the “Big
Bang”, the earth was still just a cloud of dust⑩.
What it was to become was uncertain until
between 4.5 and 3.8 billion years ago when the
dust settled into a solid globe ⑪ . The earth
became so violent ⑫ that it was not clear
whether the shape would last or not ⑬ . It
exploded loudly with fire and rock. They were
in time to ⑭ produce carbon dioxide ⑮ ,
nitrogen ⑯, water vapour ⑰ and other gases,
which were to make the earth's atmosphere ⑱.
What is even more important is that as the earth
cooled down ⑲, water began to appear on its
surface.

[第 1~2 段译文]
没有人确切知道地球是怎样开始的,因为在很久以前它就形成了。然而,根据一种普遍
为人们所接受的理论,宇宙起源于一次大爆炸,这次大爆炸将物质投射到四面八方。然后,
原子开始形成并结合成恒星和其他天体。
大爆炸后好几十亿年过去了,地球还只是一团尘埃。(随后)它变成什么没人确定,直到
45~38 亿年前,这团尘埃才慢慢地形成一个固态的球体。地球变得如此激烈动荡,以至于
不知道这个固体形状是否会继续存在下去。它(地球)猛烈的爆炸喷出了烈火和岩石,最终产
生了二氧化碳、氮气、水蒸气和其他气体,从而形成了地球的大气层。更重要的是,随着地
球冷却了下来,地球的表面开始出现了水。

在其他行星像火星上也出现了水,但和地球不同的是,这些水后来都消失了。水对生命
的发展起关键作用,这一点在当时并不明显。很多科学家相信,地球上长期有水存在,使地
球得以把有害气体和酸性物质溶解在海洋里。这就产生了一个连锁反应,使生命的发展成为
可能。
好几百万年以后,水的表面开始出现了第一批极小的植物。它们繁殖起来使得海洋充满
了氧气,这为早期的贝类及各种鱼类后来的进化创造了条件。接着,绿色植物开始在陆地上
生长。随后,陆地上出现了动物,其中有一些是昆虫,另外一些叫两栖动物,它们既能在陆
地上生活,也能在水里生活。后来,当这些植物长成森林时,爬行动物第一次出现了。它们
一般是通过孵蛋来繁衍后代的。再后来,一些叫恐龙的巨型动物出现了。它们也生蛋,在地
球上生存了一亿四千多万年。然而,六千五百万年前,恐龙时代结束了。它们为什么会突然
灭绝至今仍是个谜。恐龙的灭绝使地球上哺乳动物的兴起成为了可能。这些动物不同于以往
所有的生命形态,因为它们从体内生产出幼仔并给幼仔哺乳。
Finally about 2.6 million years ago some
small clever animals, now with hands and feet,
appeared and spread all over the earth. Thus○43
they have, in their turn○44
, become the most
important animals on the planet. But they are not
looking after the earth very well. They are putting
too much carbon dioxide into the atmosphere,
which prevents heat from escaping○45
from the
earth into space. As a result of○46
this, many
scientists believe the earth may become too hot to
live on○47
. So whether life will continue on the
earth for millions of years to come will depend on
○48
whether this problem can be solved.

too hot to live on 太热而不能在上面居住

live on 中的 on 不能省略,因为 the earth 是
其逻辑上的宾语,而 live 是不及物动词,
后须加介词才能跟宾语。
○48
depend on 取决于;依靠
[第 5 段译文]
最后,大约 260 万年前,一些小巧聪明、长着手脚的动物出现了,它们散布在地球的各
个地方。于是,他们接着成了这个行星上最重要的动物。然而,他们并没有照顾好地球,他
们把过多的二氧化碳排放到大气层中,这使得地球上的热量不能释放到太空中去。因此,许
多科学家相信地球可能会变得太热而不适合(生物的)生存。所以,在未来的数百万年中,生
命能否在地球上延续取决于这个问题能否得到解决。

A
Edmund Halley was an English scientist who lived over 200 years ago. He studied the
observations of comets (彗星) which other scientists had made. The orbit of one particular comet
was a very difficult mathematical (数学) problem. He could not figure it out. Neither could other
scientists who dealt with such problems.
However, Halley had a friend named Newton, who was a brilliant
mathematician. Newton though he had already worked out that problem,
but he could not find the papers on which he had done it. He told Halley
that the orbit of a comet had the shape of an ellipse (椭圆).
Now Halley set to work. He figured out (解决;计算出) the orbits of
some of the comets that had been observed by scientists. He made a surprising discovery. The
comets that had appeared in the years 1531, 1607, and 1682 all had the same orbit. Yet their
appearances had been 75 to 76 years apart.
This seemed very strange to Halley. The different comets followed the same orbit. The more
halley thought about it, the more he thought that there had not been three different comets, as
people thought. He decided that they had simply seen the same comet three times. The comet had
gone away and had come back again.
It was an astonishing idea! Halley felt certain enough to make a prediction (预言) of what
comet would happen in the future. He decided that this comet would appear in the year 1758.
There were 53 years to go before Halley's prediction could be tested. In 1758 the comet appeared
in the sky. Halley did not see it, for he has died some years before. Ever since then that comet has
been called Halley's comet, in his honor.
语篇解读:本文主要介绍了200多年前英国科学家哈雷以及他的发现。
1.Halley made his discovery ________.
A.by doing experiments
B.by means of his own careful observation
C.by using the work of other scientists
D.by chance
解析:选 C 细节理解题。由文中第三段“He figured out (解决;计算出) the orbits of some
of the comets that had been observed by scientists.”可知应选 C。
2.Halley made a surprising, but correct prediction in the year ________.
A.1704 B.1705
C.1706 D.1707
解析:选 B 数字计算题。第五段中的“He decided that this comet would appear in the year
1758. There were 53 years to go before Halley's prediction could be tested.”这句话告诉我们:他
预言彗星出现的时间是 1758 年,而这个预言还要经过 53 年才能验证,由此可以推断出哈雷
做出这个预言的时间是 1705 年。
3.This passage in general is about ________.
A.Halley and other scientists
B.the orbit of a comet
C.Newton and Halley
D.Halley and his discovery
解析:选 D 主旨大意题。文章的中心就是哈雷以及他的发现。
4.Which of the following is TRUE?
A.Edmund Halley was an American scientist.
B.Halley made his discovery by doing experiments.
C.Newton was a famous mathematician.
D.The orbit of a comet had the shape of a circle.
解析:选 C 细节理解题。从文章首句可以看出 A 项错误;从第 1 题的分析中可知 B
项也错误;牛顿告诉哈雷彗星的轨道是椭圆形的,可排除 D 项。
B
The plan:turn the Mars into a blue world with streams and green fields, and then fill it with
creatures from the earth.
This idea may sound like something from science fiction, but it is actually being taken
seriously by many researchers.
This suggests the future for the “red planet” will be the main topic for discussion at an
international conference hosted by NASA this week. Leading researchers as well as science fiction
writers will attend the event. It comes as NASA is preparing a multibilliondollar Mars research
programme.
“Turning the Mars into a little earth has long been a topic in science fiction , ”said
Dr.Michael Meyer, NASA's senior scientist. “Now, with scientists exploring the reality, we can
ask what are the real possibilities of changing the Mars.”
Most scientists agree that the Mars could be turned into a little earth, although much time and
money would be needed to achieve this goal. But many experts are shocked by the idea.
“We are destroying our own world at an unbelievable speed and now we are talking about
ruining another planet,” said Paul Murdin from the Institute of Astronomy, Cambridge, UK.
Over the past months, scientists have become increasingly confident they will find Martian
life forms. Europe and America's robot explorers have found the proof that water, mixed with soil,
exists in large amounts on the planet.
In addition, two different groups of scientists announced on March 28 that they had found
signs of methane (甲烷) in the Martian atmosphere; the gas is a waste product of living creatures
and could be produced by microbes (微生物) living in the red planet's soil.
But scientists such as Dr.Lisa Pratt, a biologist at Indiana University, say that these microbes
will be put in danger by the little earth project.
“Before we have even discovered if there is life on the Mars, we are talking about carrying
out projects that would destroy all these native life forms, all the strange microbes that we hope to
find buried in the soil,” said Dr. Pratt.
Monica Grady, a planetary scientist at the Natural History Museum, London, shares this
view.“We cannot risk starting a global experiment that would wipe out the precious information
we are looking for,” she said. “This is just wrong.”
语篇解读:本文是一篇科普说明文。在太空开拓人类新的生存领地一直是科幻小说的主
题,也是人类一直希望实现的梦想。如今,美国的一部分科学家想把红色火星改造成蓝色的
“生命天堂”。就这一提议科学家们展开了讨论。
5.The passage is about ________.
A.a plan turning the Mars into a little earth
B.the necessity of changing the Mars
C.finding water on the Mars
D.the Mars supporting life
解析:选 A 主旨大意题。由第一段可以看出,人们计划将火星变为一个小地球。后文
就这一计划是否应该实施进行了探讨。故文章是围绕将火星变为小地球这一话题展开的。
6.Why is Dr. Lisa Pratt against the plan?
A.Water has been found on the Mars.
B.It will cost too much money and work.
C.The native life forms on the Mars would be destroyed.
D.The earth is being destroyed at an unbelievable speed.
解析:选 C 细节理解题。由倒数第三段中的“... these microbes will be put in danger by the
little earth project.”可知,莉萨博士反对该计划的原因是担心火星上的微生物会受到破坏。
7.What could prove the existence of microbes living in the Mars' soil?
A.Liquid water on the Mars.
B.Some creatures on the Mars.
C.A lot of good soil on the Mars.
D.Signs of methane in the Mars' atmosphere.
解析:选 D 推理判断题。由倒数第四段可以看出,科学家在火星上发现了甲烷,而甲
烷是生物排放出的一种气体。由此科学家认为火星上有生物存在。
C
My friend Tim was one of five children. His father was an alcoholic and died very young,
and his mother was unable to support the family. Unfortunately, the children were separated and
placed in foster homes (收养家庭).
Tim dropped out of school and did nothing to further himself. He
eventually went through a divorce. Tim's brother, although experiencing
the same childhood, educated himself and got a good job. He has a happy family and a wonderful
home.
Both brothers gave a similar answer when asked why their lives turned out the way they did.
They said, “You'd turn out this way too if you had a childhood like mine.” Neither of the brothers
could change his past, but one of them adjusted (调整) his sail.
It doesn't take much to find an excuse whether that is our family background, our lack of
education, or that we live in the wrong city, or do not know the right people. Each one of these
excuses has a solution. However, if you believe that there is nothing you can do to turn your life
around, then you won't be able to change your life for the better.
If you really desire to turn your life to a new course, to set your sail to a different port, it is a
matter of choice. If you choose to move forward, the easiest way is to find a solution to your
today's situation. Solutions are there if you want to go after them. Sure, it may take some hard
work, or the willingness to take a risk. But if you do not, then you will never have a different or
happy life. Do not limit yourself by finding an excuse; only limit yourself by refusing to have an
excuse.
语篇解读:本文为夹叙夹议文。我们的过往是什么样子并不是很重要,因为未来掌握在
我们自己手里。
8.Why does Tim's brother have a happy life?
A.He had a happy childhood.
B.He tried hard to change his life.
C.He had a wonderful foster home.
D.He was the smartest of his family.
解析:选 B 推理判断题。由第二段“Tim's brother, although experiencing the same
childhood, educated himself and got a good job.”可知,Tim 的哥哥努力改变自己的命运。
9.What did Tim think led to his unhappy life?
A.His laziness.
B.Not adjusting his sail.
C.His unhappy childhood.
D.Not having any opportunities.
解析:选 C 细节理解题。由第三段“They said, ‘You'd turn out this way too if you had
a childhood like mine.’”可知,Tim 将自己的不幸归咎于自己不幸的童年。
10.What is the best title for the text?
A.Adjust your sail
B.Say “no” to excuses
C.Move toward a happy family
D.How we live our life is a choice
解析:选 D 标题归纳题。由最后一段“If you really desire to turn your life to a new
course, to set your sail to a different port, it is a matter of choice”可知,本文旨在告诉我们,想
过什么样的生活在于我们自己怎么选择。
Ⅱ.阅读七选五
It is often seen that in many homes young children ask their parents for a pet, and yet their
parents refuse due to the fear of spreading illnesses and the responsibility that comes with owning
a pet. __1__ Here are some things that kids can learn from pets:
Empathy (移情) and calmness. __2__ These lessons will help them in the future when they
deal with other humans. And as they take care of their pets, children learn how to be calm, gentle,
and caring, eventually growing up to be open and compassionate (有同情心的) adults.
Companionship. Once you have a pet, your kid can always depend on having a friend and
companion who will love and support him unconditionally. This makes him more selfconfident
and also helps in developing an active lifestyle. __3__
Responsibility and discipline. __4__ Research shows that training of pets also develops
discipline in kids. Appreciation of such achievements is sure to encourage them, and this will help
them in the future.
Reading skills. __5__ It is because while kids might be unwilling to read aloud in a formal
setting, like a school, they are more confident to read out to animals, as the fear of being judged is
not present.
A.Proper care leads to good relationships with the animals.
B.Pets can help with the educational development of children.
C.Having a pet will help kids learn about the circle of life and death.
D.But getting a pet is actually a good idea due to the various benefits.
E.Tasks like feeding and walking the dog teach children to be responsible.
F.This is especially important for only kids who don't have friends to play with.
G.Being with pets, kids learn that animals feel pain and want love just like humans.
