In the 1966 science-fiction (科幻) film Fantastic Voyage, a team of scientists and doctors are put into the body of an ill man to fix his body.

Such an idea, while fun, sounds surprising to many. But what if it were possible to treat an illness like cancer (癌症) by putting tiny pieces of something into the body to not only find the cancer, but also destroy it without harming anything else? Although it may seem like science fiction, tools like this are now being developed and may, in fact, become common in the near future – thanks to research now being done in the field of nanotechnology (纳米科技).

The main thing to know about nanotechnology is that it’s small – really small. Using this technology, it will be possible to discover cancer at a certain level where there are perhaps only a thousand bad cells (细胞). Compare this to what happens today: Doctors can discover cancer only after the dangerous cells have increased into the millions. One of the advantages of discovering and treating cancer at an early period is that the cells are less likely to become resistant to medicine treatment. In later period, cancer cells often change and get used to certain medicine so quickly that many medicines become ineffective.

Once a certain type of cancer is discovered, nanotechnology will also completely improve the way it is treated. Right now, most cancer treatments kill not only cancerous cells but the healthy ones as well, causing a number of side effects in people, such as hair loss and bad pain. Nanotechnology will allow doctors to destroy cancerous cells without harming healthy cells.

Unluckily, even though nanotechnology has great possibility for medical achievement, there are serious concerns that it could have bad environmental and health effects. Many scientists believe that governments should give more money for safety-related studies – to make sure that these tiny pieces of something do not get into our food and water and cause serious problems.

Meanwhile, research into the uses of nanotechnology continues and it’s developing quickly. Even ten years ago, many of these uses “would have seemed pretty unrealistic,” says Chemist Vicki Colvin. Perhaps that old movie, Fantastic Voyage, isn’t hard to believe after all.

1.According to the passage, nanotechnology ______.

A.may cause a number of side effects such as hair loss

B.may help discover and treat cancer before it is too late

C.can be used to kill both cancerous cells and healthy ones

D.can discover cancer and treat it completely in later period

2.The words “resistant to” in Paragraph 3 probably means “______”.

A.undestroyed by B.useless for C.unsatisfied with D.harmless to

3.Which of the following would be the best title for the passage?

A.The Advantages of Nanotechnology.

B.The Near Future of Science Fiction.

C.A Tool for Creating Medicine?

D.A Treatment for Cancer?

九年级英语阅读理解中等难度题查看答案及解析

Scientists who study the climate are still arguing about how fast the earth is warming and how much it will warm, but they do agree that the earth is warming and that it will keep warming if we don’t do anything about it.

Scientists agree that the burning of fossil fuels (化石燃料) like oil and coal cause greenhouse gases to escape into the air and that these gases are causing most of the warming. Another cause is deforestation (cutting down trees) . Trees soak up carbon dioxide, one of the greenhouse gases, from the air.

There are already some changes happening because of global warming. Sea level is rising and some animals are already moving to new homes. It’s already too late to stop global warming completely.

If the warming gets worse, as scientists expect, there may be some kinds of plants and animals that is disappearing because they can’t move to new homes. There may be more storms and floods. Sea level may rise so much that people have to move away from the coasts. Some areas may become too dry for farming.

Global warming is a very difficult problem to fix. People are having a hard time agreeing on what to do about it. For example, everyone agrees that wasting energy is a bad thing to do. But some people think that the federal government (联邦政府) should make laws about it, while other people think it should be up to each person or business to decide what to do.

Many states and businesses in the United States are not waiting until the federal government decides what to do. They have already started working on the problem.

1.What are the scientists arguing about in the passage?

A. How fast is the earth warming?                  B. How much will the earth warm?

C. The earth will keep warming if we don’t do anything about it.    D. Both A and B.

2.What does the underlined phrase “soak up” mean?

A．take in            B．grow up           C．take off           D．set up

3.What may be the causes of global warming?

A．The disappearance of plants and animals and the wasting energy.

B．The burning of fossil fuels and storms and floods.

C．The burning of fossil fuels and deforestation.

D．The rising of sea level and deforestation.

4.What is the best title of this passage?

A．The reason for global warming             B．How to stop global warming

C．The changes to the world                 D．The global warming
