What will people die of 100 years from now? If you think that is a simple question, you have not been paying attention to the revolution that is taking place in bio-technology(生物技术). With the help of new medicine, the human body will last a very long time. Death will come mainly from accidents, murder and war. Today's leading killers, such as heart diseases, cancer, and aging itself, will become distant memory.

In discussion of technological changes, the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live? Human brains were known to decide the final death. Cells(细胞) are the basic units of all living things, and until recently, scientists were sure that the life of cells could not go much beyond 120 years because the basic materials of cells, such as those of brain cells, would not last forever. But the upper limits will be broken by new medicine. Sometime between 2050 and 2100, medicine will have advanced to the point at which every 10 years or so, people will be able to take medicine to repair their organs(器官). The medicine, made up of the basic building materials of life, will build new brain cells, heart cells, and so on---in much the same way our bodies make new skin cells to take the place of old ones.

It is exciting to imagine that the advance in technology may be changing the most basic conditional human existence, but many technical problems still must be cleared up on the way to this wonderful future.

1. According to the passage, human death is now mainly caused by _______.

A. diseases and aging                B. accidents and war

C. accidents and aging               D. heart diseases and war

2. In the author's opinion, today's most important advance in technology lies in _____.

A. medicine      B. the internet     C. brain cells    D. human organs

3.Humans may live longer in the future because ______.

A. heart disease will be far away from us

B. human brains can decide the final death

高一英语阅读理解中等难度题查看答案及解析

New research has found that even if you give up smoking,the damage it has done to your genes（基因）will stay there for a much longer time.

In the research,a team of US scientists studied the blood of 16,000 people.Among them, some were smokers,some used to smoke,and the rest were non-smokers.Scientists compared their genes and found that more than 7,000 genes of smokers had changed a number that is one-third of known human genes.

According to NBC News,both heart disease and cancer are caused by genetic changes. Some people may have had the changes when they were born,but most people get them in their day-to-day lives while doing things like smoking.

When you stop smoking,a lot of these genes will return to normal within five years.This means your body is trying to heal（治愈）itself of the harmful effects of smoking.But the changes in some of the genes stay for longer.They can stay for as long as 30 years.It’s almost like leaving a footprint on wet cement（水泥）— it will always be there, even when you’ve walked away and when the cement becomes dry.

Although the study results may make people unhappy,there is a bright side: the findings could help scientists invent medicine to treat genetic damage caused by smoking or find ways to tell which people have heart disease or cancer ricks.

1.The function of Paragraph 1 is to ______________.

A. give an example　　 B. show the main idea of the passage

C. make an argument　　 D. introduce the topic of the passage

2.Most genetic changes happen because of  ____________.

A. people's bad living habits　　 B. environmental pollution

C. people's condition at birth　　 D. heart disease and cancer

3.The underlined word "it" in Paragraph 4 refers to ________________.

A. the cement　　 B. the footprint

C. the harmful　　 D. the genetic change

4.Which of the following statements is true?

A. The findings help to find treatments for genetic damage caused by smoking.

B. The findings have prevented more people from starting smoking.

C. The findings offer evidence that a damaged gene can heal itself.

D. The findings are the fruit of more than three years' research
