Sometime early in the next century, human beings will move to Mars. They will live there for about a year, and then will be replaced with another group of pioneers. Building the base on Mars will advance our knowledge of the solar system and aid in our understanding of the earth.

We already know that Mars resembles the earth in many aspects: general size, presence of water, length of day, range of temperatures. These resemblances have caused many people to consider a centuries-long project: to terraform Mars. Terraforming means altering a planet’s surface so that Earth’s life forms can survive there. This concept, previously found only in science fiction is now being seriously considered by scientists.

Terraforming Mars is theoretically simple: add nitrogen and oxygen to the atmosphere; pump water to the surface; and add the earth’s plants and animals in the order in which they developed on Earth. But it will take at least 300 years.

Some people think that such a project is too huge for humans to undertake, but there are very good reasons to make the attempt. The earth now contains some 6 billion people, and no one has any idea of how many humans the earth can support. Our very existence and numbers are threatening many other species. We also have had some experience with terraforming our own planet: altering the landscape, the atmosphere and the climate. Currently terraforming earth has become a wiser activity as we try to control global warming, air and water pollution, and preserve some natural living places.

While the possibility of such a project is small, it is not impossible .Even if earth –bound societies come and go in the next 300 years, the project can continue through the work of the Mars settlers without the need for constant backing from the earth.

The future existence of all the people in our world may very well depend upon our ability to terraform Mars.

1.What would be the best title for this passage?

The establishment of this base on Mars will advance our knowledge of the solar system and aid in our understanding of the earth.

【2】We already know that Mars is like the earth in many ways: general size; presence of water; length of day; range of temperatures. These similarities have caused many people to consider a century-long project: to terraform Mars. Terraforming means changing a planet’s surface so that Earth’s life forms can survive there. This concept, previously found only in science fiction is now being seriously considered by scientists.

【3】Terraforming Mars is theoretically simple: add nitrogen and oxygen to the atmosphere; pump water to the surface; and add the earth’s plants and animals in the order in which they developed on Earth. But it will take at least 300 years.

【4】Some people think that such a project is too huge for humans to accomplish, but there are very good reasons to make the attempt. The earth now contains some 7 billion people, and no one knows how many humans the earth can support. Our very existence and numbers are threatening many other species with extinction. We also have had some experience with terraforming our own planet: changing the landscape, the atmosphere and the climate. At present, we are aware of the importance of terraforming the earth as we try to control global warming, air and water pollution, and protect some natural habitats.

Many psychologists in the early twentieth century believed that humans use only 10 percent of their brains, and even the great Albert Einstein once wrote that most people use only a small portion of the grey matter between their ears. It's a theory that has often been put forward in television documentaries; magazines, advertisements and books over the past century.

But nearly all scientists now agree the 10 percent theory is completely unfounded. In fact, they question how this figure was ever arrived at in the first place and what areas of the brain are supposed to be unneeded. The theory supposes that if 90 percent of the brain were removed, a person would Still be able to function normally, while in reality it is known that damage to even a small area of the brain can result in extremely serious physical injury different activities and that many areas of the brain are used at the same time for some complex activities or thought processes.

Throughout the course of one day, most .areas of the brain are active at some time, even during sleep. The 10 percent theory suggests that certain areas o' the brain are not used, but scans slow activities throughout the entire brain and not in any separate part. The final argument against the 10 percent theory is the fact that doctors carefully map the brain before removing brain cancers so that they don't affect other essential areas.

From an evolutionary point of view, it's highly unlikely butt our comparatively larger brains would have evolved from our ancestors if the extra areas were not needed. In fact, there is absolutely no evidence support the 1p percent theory.

1.How did the 10 percent theory get such widespread popularity?

A. It was promoted in various types of copular media.

B. Albert Einstein argued strongly in support.

C. It was proven in scientific research.

D. Few people could prove it wrong.

2.The underlined word "unfounded" is chest in meaning to _________.

A. undiscovered         B. unproven        C. unknown        D. unnecessary

3.Which of the following is true according to the writer?

A. We use less than 10% of our brains.

B. Most brain disorders affect the same part of the brain.

C. The brain is less active during times of sleep.

D. The 10 percent theory does not make evolutionary sense.

4.What can we infer from the passage?

A. People today use more of their brain than in the past.

B. Scientific opinion about the topic of brain use is equally divided.

C. Our understanding of the brain has changed greatly in the past decades.

D. Modern scientists have a complete picture of how the brain works.

5.What is the main purpose of the passage?

A. To present two sides of brain theory.

B. To criticize the 10 percent theory.

C. To explain how brain works.

D. To describe the history of brain research.

高三英语阅读理解中等难度题查看答案及解析

In France, a man walks on what can only be described as a human-sized hamster wheel. The wheel moves around and around, as the man keeps walking. What is he doing? He is lifting a heavy object to the top of a tower the same way workers moved such objects 800 years ago.

In the 13th century, workers did not have the 100-meter tall cranes they now use to build tall buildings. So they had to be creative and come up with simple machines to get their work done.

The man on the large wheel is walking at a reasonable speed. The wheel turns and pulls a rope connected to a pulley(滑轮)at the top of the tower. Another rope tied to the pulley lifts supplies from the ground.

This is just one way skilled craftsmen arc building a 13th-century castle without using modern tools. Crew have been working on the castle since 1997. It is being built in the Burgundy area of central France. Organizers expect the work to last another 10 to 15 years. That means it will take close to 30 years to finish the project.

The crew are making progress at about half the speed of the workers from 800 years ago. That is because many of them are accustomed to using modern tools. When the crew use heavy chisels(凿子）and hammers to break rock, as they did hundreds of years ago, they are learning as they go. The goal of the project is to learn more about old building techniques in case they might be of use today.

Clement Guerard, 44,is a stonemason; he cuts and builds with stone. He has been working on the tower for 17 years. He said one way he is able to work on something like this for so long is by forgetting “some of the pace of modern life", he is able to adapt to working by hand.

1.Why is the man walking in the wheel?

A. To draw the attention of passers-by.　　 B. To act as an ancient building worker.

C. To test an ancient machine for building.　　 D. To raise building materials to the building top.

2.What makes the project last so long?

A. The quality it requires.　　 B. The ancient way to built it.

C. Its huge size.　　 D. Its great height.

3.What’s the purpose of building the tower in the ancient way?

A. To build a unique ancient building.　　 B. To copy a famous ancient building.

C. To master ancient building techniques.　　 D. To experience ancient way of building.

4.Why has Clement Guerard worked such a long time for the tower?

A. He in used to doing handwork.　　 B. He can get a steady income.

C. He forgets how to do other jobs.　　 D. He likes building ancient buildings.
