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. 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 |
C.people are living longer due to better living conditions |
D.new lands are being made into farmlands |
The author says that in areas with large populations, land might be more productively farmed if _____.
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 |
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 |
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. |
Severely disabled people may soon be able to use their noses to write, drive a wheelchair or surf the Internet, thanks to a device (装置) developed by doctors in Israel.
The device will be used by breathing in and out through the nose, according to a study. Healthy people who tested the device quickly learned to play computer games and write sentences by sniffing. Encouraged by the results, the researchers decided to test their device on people who are paralyzed (瘫痪) but whose intelligence remains normal. Ten paralyzed who tested the device quickly learned to use their noses to write words, open a webpage, copy words and put them into a search engine.
With their success in helping severely disabled people to communicate * the researchers decided to make use of the new technology to design an electric wheelchair to be driven by sniffs.
Ten healthy people easily mastered sniff—driving a wheelchair through a maze (迷宫), and a 30-year-old man who had been paralyzed from the neck down for six years was as good a sniff-driver as the healthy participants at his second attempt. In other words, a paralyzed person could use the sniff controller to drive an electric wheelchair.
At the moment, sniff-controlled technology is still in the stage of development, and the Weizmann Institute has already applied for a patent on the device. "Ill be very happy if it can help us to make money, but the real problem is that I hope someone will develop it, because this would help a lot of people," said Sobel, one of the lead researchers of the study.What’s the purpose of the passage?
A.To introduce a new invention. |
B.To equip the disabled with life skills. |
C.To show the nose's special functions. |
D.To instruct doctors to apply for a patent. |
In the test, the paralyzed people with normal intelligence can use their nose to ______.
A.type long sentences quickly |
B.play computer games easily |
C.enter a website without much difficulty |

A.spent six years learning how to drive a wheelchair |
B.failed to drive through the maze at his first attempt |
C.took the wheelchair controlled by healthy participants |
D.managed to drive an electric wheelchair by sniffing |
From the last paragraph, we can infer that the sniff-controlled technology ______.
A.will be applied to other fields of research |
B.needs further developing to serve more people |
C.has become an important patented invention |
D.shows the wisdom and talents of Israel doctors |

How do you know if your home is an easy aim for thefts ? Around the holidays, many families don't consider taking proper measures to prevent their homes from suffering holiday thefts. With just a few simple steps, you can better make sure of the safety of your home during all of the holiday celebrations. Here are a few tips for making it difficult to tell you are away from home.
● Either have a trusted neighbor pick up your mail and newspapers, or tell your mailperson to hold your mail until you return. Nothing says "Hey, we are not home!" like when your postbox is filled with all kinds of mails and you have many different newspapers in your driveway.
● Set several different lights in your house on random timers (随机定时器). Don't leave your outdoor lights on all the time. Instead, put your outside lights on timers to be on during the nights. If an outdoor light remains on for days at a time, it means that nobody is home to turn it off.
● If you have pets that you are not taking with you on vacation, leave them with a friend, rather than having someone come into your house every day to take care of them. When thefts see a neighbor or friend entering your house every day, they will know you are not home.
● Close all your curtains when you leave town. This is effective to deter possible thefts, as no one can see what is in your house. If they don't know what there is to take, then the risk is even greater for them to break in.

When I was 13, my bedroom walls were covered with posters of the Monkees and Beatles. I wrote fan letters and daydreamed about meeting the objects of my affections. I begged my parents to attend every rock concert and watch every TV show featuring my favorite celebrities (名人) ; my friends and I discussed for hours all the things we would say and do when we met our favorite movie stars and pop singers. I drove my mother crazy! But after a few years, my obsession (迷恋) stars faded as I matured and gained the confidence to socialize with "real" boys.
In the 35 years since I was a teenager, celebrity worship (崇拜) has increased among teens due to the explosion of television celebrity gossip shows, and instant access to celebrity news on the Internet. It's no wonder that many teens are obsessed with stars when news programs often are filled with entertainment stories and the lives of celebrities.
Celebrity worship syndrome (综合征) is now considered a personality disorder. While it is normal for teenagers to follow the lives of their favorite stars, parents should try to monitor everything their child finds interesting. Parents should take action if they suspect a teen is too obsessed with celebrities and showing little interest in school or withdrawing from the family. When teens talk a lot about celebrities and view them as just means of entertainment, this is considered normal celebrity worship. However, when a teenager is obsessed with a star and often expresses a desire to have a close personal relationship with a celebrity or feels they have a special connection to a star, this may be the time for concern.
Recent studies have shown that teens who develop an unhealthy obsession with celebrities often suffer from low self confidence and depression. Teens who are overly obsessed with stars often have damaged relationships with their parents.We learn from the second paragraph that ____.
A.teens today are not so obsessed with celebrities |
B.the author is surprised at celebrity worship |
C.the media greatly contributes to celebrity worship today |
D.celebrities expose their lives too much |
Parents should become concerned when their children ____.
A.talk a lot about celebrities with others |
B.put up celebrity posters in their bedrooms |
C.ask to go to their favorite star's concert |
D.desire a close personal relationship with their favorite star |
The last paragraph implies that ____.
A.parents should not care too much about a child's celebrity worship |
B.children can normally get out of celebrity worship when they are older |
C.children with celebrity worship usually have high opinion of themselves |
D.celebrity worship syndrome can be a serious problem if left overlooked |
What is most likely to be talked about in the paragraph following the passage?
A.The harm of celebrity worship syndrome. |
B.What to do with children's celebrity worship syndrome. |
C.More signs of celebrity worship syndrome. |
D.Who will suffer most from celebrity worship syndrome. |
