As people slowly learn to cure diseases, control floods, prevent hunger, and stop wars, fewer people die every year. As a result, the population of the world is becoming larger. In 1925 there were about 2 billion people in the world; today there are over 6 billion.
When the number rises, extra mouths must be fed. New lands must be brought under development, or land already farmed must be made to produce more crops. In some areas the land is so over-developed that it will be difficult to make it provide more crops. In some areas the population is so large that the land is divided into too tiny units to make improvement possible with farming methods. If a large part of this farming population went into industrial work, the land might be farmed much more productively (多产地) with modern methods.
There is now a race for science, technology, and industry to keep the output of food rising faster than the number of people to be fed. New types of crops, which will grow well in bad weather, are being developed, so there are now farms beyond the Arctic Circle in Siberia and North America. Irrigation (灌溉) and dry-farming methods bring poor lands under the plough. Dams hold back the waters of great rivers, which can provide water for the fields in all seasons and provide electric power for new industries. Industrial chemistry provides fertilizer to suit different soils. Every year, some new methods are made to increase or to protect the food of the world.
1.The author says that the world population is increasing because _____.
A. there are many rich valleys and large fields
B. farmers are producing more crops than before

A. the land was divided into smaller pieces
B. people moved into the countryside
C. industrial methods were used in farming
D. the units of land were much larger
3.We are told that there are now farms beyond the Arctic Circle. This has been made possible by _____.
A. growing new types of crops
B. irrigation and dry-farming means
C. providing fertilizers
D. destroying pests and diseases
4.Why is the land divided into tiny units in some areas?
A. There are too many people living there.
B. It saves more natural resources there.
C. It prevents crops from serious diseases there.
D. Farmers can grow various kinds of crops there.
5.Why do some people use dams to hold back waters from great rivers?
A. To develop a new kind of dry-farming methods.
B. To prevent crops from floods.
C. To provide water and electricity in all seasons.
D. To water poor lands in bad weather.

高二英语阅读理解简单题查看答案及解析
As we have seen, the focus of medical care in our society has been shifting from curing disease to preventing disease-especially in changing our many unhealthy behaviors, such as poor eating habits, smoking, and failure to exercise. The line of thought about this shift can be pursued further. Imagine a person who is about the right weight, but does not eat very nutritious foods, who feels OK but exercises only occasionally, who goes to work every day, but is not an outstanding worker, who drinks a few beers at home most nights but does not drive while drunk, and who has no chest pains or abnormal blood counts, but sleeps a lot and often feels tired. This person is not ill. He may not even be at risk for any particular disease. But we can imagine that this person could be a lot healthier.
The field of medicine has not traditionally distinguished between someone who is just “not ill” and someone who is in excellent health and pays attention to the body’s special needs. Both types have simply been called “well”. In recent years, however, some health specialists have begun to apply the terms “well” and “wellness” only to those who are actively attempting to maintain and improve their health. People who are well are concerned with nutrition and exercise, and they make a point of monitoring their body’s condition. Most important, perhaps, people who are well take active responsibility for all matters related to their health. Even people who have a physical disease or handicap (缺陷) may be “well”, in this new sense, if they make an effort to maintain the best possible health they can in the face of their physical limitations. “Wellness” may perhaps best be viewed not as a state that people can achieve, but as an ideal that people can struggle for. People who are well are likely to be better able to resist disease and to fight disease when it strikes. And by focusing attention on healthy ways of living, the concept of wellness can have a beneficial influence on the ways in which people face the challenges of daily life.
1.Today’s medical care is placing more stress on ________.
A. monitoring patients’ body functions
B. removing people’s bad living habits
C. ensuring people’s psychological well-being
D. keeping people in a healthy physical condition
2.Traditionally, a person is considered “well” if he or she ________.
A. is free from any kind of disease
B. does not have any physical handicaps
C. attempts to maintain the best possible health
D. keeps a proper balance between work and leisure
3.According to the passage, which of the following is WRONG?
A. Wellness is now just an ideal in many people’s mind.
B. Someone who drinks a few beers at home most nights is not healthy.
C. The concept of wellness can help people face the challenges of daily life.
D. A man without any physical or mental problem may not be really healthy.
4.According to the author, healthy people are those who ________.
A. do not have any symptoms of disease
B. have strong muscles as well as slim figures
C. try to keep healthy as possible, regardless of their limitations
D. can recover from illness even without seeking medical care

As digital technology increasingly controls the lives of young people, scientists have begun to wonder: Is the Internet good or bad for kids?
“It’s impossible to answer that question because the Internet is so many things,” says psychologist Patricia Greenfield. “It’s networked computer games and news about politics and instant messaging and e-mails to your grandmother. It can be both an educational resource and a hiding place for kidnappers.”
Adults have many reasons to worry about kids’ Internet use. In chat rooms, for instance, it is easy to lie and kids can get trapped in dangerous situations. In searching for and visiting websites, kids can come across words and pictures that they may not be prepared for. To help prevent that situation, in 2000, the US Congress passed the Children’s Internet Protection Act, which requires schools to block offensive and obscene(淫秽的)websites.
Researches have pointed out how confusing the Internet can be for children, even when they think they know how it works. To find out how much kids know about the technology, Zheng Yan, an educational professor in New York, interviews over 300 students in grades four to eight. Most of the youngest students think the Internet is simply an icon (图标) on the screen. It often isn’t until 10 that kids realize that the Internet is a network of millions of computers. It takes another 2 or 3 years for them to understand that a stranger can see what they’ve posted.
Understanding the technology helps kids understand how dangerous the web can be. It’s not simply enough to block harmful websites or to limit the number of hours kids spend online. Learning about the Internet can also give young people the power to use it in beneficial ways.
1.By saying “the Internet is so many things”, Patricia Greenfield means that ______.
A. computer technology is hard for people to master
B. computers have more disadvantages than expected
C. computers have more advantages than expected
D. computers bring advantages as well as disadvantages
2.According to the Children’s Internet Protection Act passed in 2000, ______.
A. children are not allowed to go online at schools
B. schools must watch students’ behavior all the time
C. children must be prevented from having access to unhealthy websites
D. it is against the law to search for unhealthy information online
3.In the mind of very young children, the Internet is ______.
A. harmful B. simple
C. a complicated network D. a news source
4.What might be talked about in the following paragraph?
A. How to protect children against the danger of the Internet.
B. How to use the Internet for beneficial purposes.
C. What the public think of the Children’s Internet Protection Act
D. How the Children’s Internet Protection Act was passed.
