精英家教網 > 高中英語 > 題目詳情

Life on earth depends on water, and there is no substitute for it. The current assumption is that our basic needs for water — whether for drinking, agriculture, industry or the raising of fish will always have to be met . Given that premise (前提), there are two basic routes we can go: more equal access to water or better engineering solutions.

Looking at the engineering solution first, a lot of my research concentrates on what happens to wetlands when you build dams in river basins, particularly in Africa. The ecology of such areas is almost entirely driven by the seasonal changes of the river — the pulse of the water. And the fact is that if you build a dam, you generally spoil the downstream ecology. In the past, such problems have been hidden by a lack of information. But in the near future, governments will have no excuse for their ignorance.

The engineers’ ability to control water flows has created new kinds of unpredictability, too. Dams in Africa have meant fewer fish, less grazing and less floodplain (洪泛區) agriculture — none of which were expected. And their average economic life is assumed to be thirty years. Dams don’t exist forever, but what will replace them is not clear.

The challenge for the future is to find new means of controlling water. Although GM technology (轉基因) will allow us to breed better dry-land crops, there is no market for companies to develop crops suitable for the micro-climates of the Sahel and elsewhere in Africa. Who is going to pay for research on locally appropriate crops in the Third World?

1.What’s the main idea of this passage?

A.The engineering solutions to water resource and their limitation.

B.The challenge for the future.

C.The basic means of controlling water.

D.The challenge for developing crops.

2. Which of the following statements is NOT true for meeting our basic needs for water?

A.Water resource should be used more reasonably.

B.More dams should be built in river basins.

C.More wetlands should be protected from destruction.

D.More dry-land crops could be developed in Africa.

3. The author suggests that governments will have no excuse for their careless ignorance in the future because        .

A.The ecological destruction will be known to the public by researchers

B.The ecological destruction will no longer be a problem in the future

C.The future is an information age

D.Governments will face greater challenge in the future

4.The author mentions all the problems caused by dams EXCEPT          .

A.fewer fish

B.less grazing land

C.less floodplain agriculture

D.less farming land

5.The last sentence probably implies that          .

A.No one will invest in developing locally appropriate crops in Africa

B.Researchers have no interest in developing dry-land crops

C.Research on locally appropriate crops in the Third World may be profitable

D.There is less water resource in the Third Worldk*s*5u

E
A United Nations report says the number of people in the world is expected to reach 6500 million this July. By the middle of the century, the population could reach more than 9000 million. That would be an increase of 40﹪.
These numbers are fresh estimates for a report on world population change from 1950 to 2050. Hania Zlotnik is director of the U.N. Population Division. She says the world has added nearly 500 million people in the last six years.
But, in her words, "the good news is that new estimates show that it will take a little longer" to add the next 500 million. Mizz Zlotnik says this will probably happen by 2013.
The U.N. report says most population growth by 2050 will take place in less developed countries. Their population is expected to increase from 5000 million today to almost 8000 million. The population of more developed nations is expected to stay about the same, at just over 1000 million.
The report says nine countries will be responsible for about half the world population increase by 2050. These include Bangladesh, China, the Democratic Republic of Congo, Ethiopia and India. The others are Nigeria, Pakistan, Uganda and the United States.
Twelve countries are expected to have populations at least three times the size now. These include Afghanistan, Burkina Faso, Burundi, Chad, Congo and the Democratic Republic of Congo, and East Timor. The others are Guinea-Bissau, Liberia, Mali, Niger and Uganda.
The report says birth rates remain low in forty-four developed countries.
Today, worldwide, there is an average of two-point-six children per woman. This number is expected to fall to just over two children per woman in  2050. But U.N. population experts note that they cannot be sure which way birth rates will go in the future.
The U.N. report also notes that AIDS has increased death rates and slowed population growth in sixty countries. The area most affected by the disease is Southern Africa.
There, how long people live has fallen from an average of sixty-two years in 1995 to forty-eight now. Researchers believe life expectancy will fall to forty-three years by 2015, then begin a slow recovery.
67. Which of the following statements is true?
A. The population growth will slow down in the next few years.
B. Most population growth will take place in developed countries.
C. There is an average of 2.6 children per woman in developed countries.
D. The area most affected by AIDS is Uganda.
68. Which one is the best title of this passage?
A. AIDS slowed population growth.
B. Most population growth will take place in less developed countries.
C. Population growth and death rate.
D. UN world population report.
69.The author believes that the population growth results from_______
A. The birth rate in developed countries is too high.
B. The birth rate in developing countries is too high.
C. AIDS hit only a few countries.
D. A decrease in death rate.
70. Which of the following best describe the author’s attitude towards the rapid population growth?
A. sympathetic     B. happy       C. optimistic     D. critical

Lexi Peters, a 14-year-old girl in New York, loves hockey. She’s not only good at playing on her after-school team, but also at playing hockey video games. But when Peters played the popular NHL (National Hockey League) games made by Electronic Arts, something really bothered her. The virtual (虛擬的) character in the game could only be a boy — not a girl.
She didn’t think that was reasonable. There must be many girls playing hockey in the US. So she wrote a letter to Electronic Arts.
“Being represented by a man is unfair to women and girl hockey players,” Peters wrote. “Women’s hockey is a fast-growing sport. I am confident that I’m not the only woman interested in the opportunity to create herself in the game.”
Several weeks later, Peters received an unexpected e-mail from the senior producer for EA Sports’ NHL games, David Littman. “Hi, Lexi,” the e-mail began. “We agree with you!”
Electronic Arts said it would create a female player in the game. “I was thinking you could be the model,” Littman wrote. Peters almost couldn’t believe it. Later, she sent photos of herself taken at all different angles (角度).
And so, when Electronic Arts released the newest version of their game, NHL 12, this fall, Peters was the face of the female player. She can now skate with the NHL’s great players. “It’s strange at first, but you get used to it,” said Peters. “It’s really funny and cool.”
For Peters, there is also an important lesson that she will take with her the rest of her life. “If you have something to say, and you think it’s important, go for it!” she said.
【小題1】What bothered Peters when playing NHL games?

A.There was no girl character in the game.
B.The characters were not real at all.
C.No girls would like to play the game.
D.It was not like playing real hockey games.
【小題2】According to Peters’ letter, we can know that ________.
A.girls were not allowed to play hockey in the past
B.female players can be represented by men
C.boys don’t like to play hockey with girls
D.more and more girls are interested in hockey
【小題3】What was David Littman’s opinion of Peters’ letter?
A.He ignored it.B.He disliked it.
C.He agreed to it.D.He voted against it.
【小題4】Peters’ experience tells us that we should ________.
A.enjoy the fun of being a model
B.do what you think important to do
C.work hard to get used to any new situation
D.think about problems from different angles

Tree of Life: the incredible biodiversity of life on earth Rochelle Strauss Illustrated by Margot Thompson 2004,
Toronto: Kids Can Press, $ 16. 95.
Grades 3 to 6.

1. This picture book explores the life of a tree that has deep roots, long arms, and many children. She provides
shelter for many animals and bears fruit. The author uses colorful, simple, yet detailed watercolor illustrations
to convey her words. The charming pictures show the many aspects in the life of a tree down to the caterpillars that eat the leaves. It is good for pre-school children.
2. This charming picture book highlights the life of a garden, from planting seeds to harvesting. With the
narrator as guide, the reader is led through a variety of free verse and occasionally rhymed poems that fill in the
story of a garden and its inhabitants. The pictures, delightful watercolors in bright pastels, add to the whimsical
feel of the poems. Young readers will certainly enjoy this fun and fanciful text.
3. This is a story from 1956 which introduces a little boy who likes to go fishing with a tree limb, a worm, and
a pin. Although he never catches anything, on this particular day he finally does hook three big ones, but the little one gets away. The boy pulls them home in his wagon and his mother cooks them for supper. The swinging
rhythms of the text and the good humor evident in the illustrations remain fun for the youngest readers.
4. This useful, attractive, oversize volume uses its height well, employing a tree metaphor to show the earth's
various kinds of life and how all living things, from bacteria to the largest mammals, are related. Each. spread
covers one branch of the animal kingdom. To make the enormity of species understandable, Strauss equates
individual species( e. g.,10,000 bacteria) with one leaf on the tree.
5.This is a story about how a grandfather teaches his eager granddaughter to catch speckled trout from the
stream in springtime. After a whole day on the lake, only Grandpa is lucky. The next morning the young
fisherman hurries to the dock alone, and soon she hooks the catch of a lifetime. Young readers will appreciate
this story that celebrates the special bond between the older and younger generation, while brilliant watercolor
illustrations capture the beauty of the natural world.

Read the following text and choose the most suitable heading from A-F for each paragraph. There is one extra heading which you do not need. F=A+E

A. Hoping to enjoy the fun of college life again

B. No idea of a lifelong profession

C. Confusion before graduation

D. What I want to do in the future

E. Cherishing the memory of my college life

F. My college experience in the second year

94. ___________

After four years, the time has come. In less than two weeks, I will have graduated. I look back now and I can't believe how fast it all went. I can still remember the first day of classes, looking on the map on the back of the Schedule of Classes and asking where the classroom building was. Now I'm a senior, looking at freshmen with envy. Every day I wish I could freeze time, and make the next two weeks go more slowly. I know a lot of people who can't wait to graduate, but for me it's the opposite. I want to turn back time instead and cherish every day of my college experience once again.

95. ____________

For me, college has been a great learning experience, and most of the learning process has taken place outside of the classroom. My second year of college was perhaps the most remarkable year of my life. This was the year that I finally convinced my mom that I was going to be OK living on campus, and she finally let me go. This was the year that I made some lifelong friends, and through many triumphs and failures I came to know more about myself. My second year involved experimenting with new things, such as camping in mountains, attempting to present some lousy poems to newspapers and drawing cartoons of my teachers in class.

96. _____________

As I walk down the familiar routes on campus, I find myself doing a lot of soul-searching and reminiscing. I find myself wanting to start all over again and recapture the fun and excitement of my college days. I have been panicking at the idea of graduating. I have been going to school for as long as I can remember, and I feel like there is so much more that I want to learn, but instead I have to graduate. The world is enormous and the possibilities are endless. For the past four years I have been surrounded with a safety net. The student status has been a somewhat comforting feeling, giving me an escape from the realities of the world outside.

97. _____________

With less than two weeks left of school, I'm getting a queasy feeling deep down every time I think about the fact that I'm going to be graduating. For as long as I can remember, I have been a student. I feel like I'm living in denial about graduating. Every time I get asked about what I'm going to do after college I feel like screaming at the top of my lungs. I don't know what I want to do with the rest of my life. It's too difficult to even contemplate the idea that soon I will be waking up in the mornings and not have a class to which I should be going.

98. ______________________________

On a recent interview, I was asked, "Is this the profession you want for the rest of your life?" I was amused and almost laughed at the question, but I gave an honest answer. I don't know what the future holds. During the last four years I have changed my mind so many times, the idea of a lifetime commitment to a certain job seems like torture.
