Write a multi-choice question for the following article: Article: Our planet is home to about seven billion people. Since the 1990s, population experts have predicted the number would grow to nine billion before it begins to slow down and possibly decrease. But a new report predicts the world's population is likely to increase to almost 11 billion by 2100. Based on the most modern statistical tools, the new report makes use of government records and considers expert predictions, including death rates, birthrates and international migration, or people moving across borders. The report says during the rest of this century, Africa's population will grow from about 3.5 billion to 5.1 billion over the next 85 years John is director of the United Nations Population Division. He says that in the past, researchers thought population growth in Africa would be similar to that of other areas. They expected slower growth rates as birth control use became more widespread. But he says those ideas were wrong. "The level of contraception use has continued to increase but slowly -- more slowly than expected, and birthrate therefore has been falling less rapidly than expected, and the population therefore continues to grow somewhat more rapidly than we expected.The new findings are based on a joint research project of the United Nations and the University of Washington. The researchers believe the population of Asia will reach five billion by 2050. That is up from the current 4.4 billion. And then begin to decline. The researchers also believe that North America, Europe, Latin America and the Caribbean area will have a total population of below one billion. John says the pressure of feeding the rising population is likely to be less than that might be expected. "The relatively good news is that the world has been winning the race between population growth and food production. If you look back historically over the last 50 years, certainly for the world as a whole and for many, most individual countries and regions, the increase in food production has outpaced the increase of population.||"
Ans: Question: Which area will experience the largest increase in population at the end of the century?Options:A Asia.B Africa.C Europe.D North America.Answer:B

Write a multi-choice question for the following article: Article: Last night I drove a long way (about 500 km) to return home. It was late and I was driving fast because I wanted to get home as soon as possible. So several times when I was driving behind a slow-moving truck on a narrow road, I wanted to shout at the driver ahead. Then I came to a crossroad with a traffic light. As I drove near, it turned red. I stopped my car at once. I looked left,right and behind. I found no cars or persons -- I was alone on the road. The person who would come to the crossroad was at least a mile away in any direction. Certainly going through the light would cause no danger. I could pass the traffic light. But strangely enough, I just stopped there, waiting for several minutes until the light went green. I asked myself why I refused to run the light. Surely it was unnecessary for me to be afraid of danger or being fined , because there were no cars or police around at all. But I remained waiting until the light changed. When I finally got home, it was near midnight. My wife had fallen asleep. The question of why I stopped for that light came back to me again, because I stopped another two times for the red lights as "special" as the first one. I stopped, not because of the law, but because it was a good habit I had developed. In fact, we were used to doing something right just because we have made obeying the rules a good habit. We do it just because we should do it. I thought if another man met with the same thing, he would make the same choice. I believed so. And I could be trusted by others. I believed that everyone would and could control himself/herself well. It was amazing that we trusted each other to do the right things, wasn't it?
Ans: Question: The author waited until the light went green because _ .Options:A running the light would make him finedB he was afraid to cause an accidentC he was prevented by the passers-byD he was used to obeying traffic rulesAnswer:D

Write a multi-choice question for the following article: Article: Perhaps it is hard to imagine that a bad tooth could be deadly. But doctors in the Washington area say a twelveyearold boy died last month of a tooth infection that spread to his brain. They say it might have been prevented if the boy had received the dental care he needed. Experts at the National Institutes of Health say good dental care should start at birth. They say breast milk is the best food for the healthy development of teeth. Breast milk can help slow bacterial growth and acid production in the mouth. When baby's teeth begin to appear,you can clean them with a wet toothbrush. Dentists say it is important to find soft toothbrushes made especially for babies,and use them very gently. The use of fluoride to protect teeth is common in many parts of the world. This natural element is often added to drinking water supplies. The fluoride mixes with enamel ,the hard surface on teeth,to help prevent holes,or cavities from forming. But the American Academy of Pediatric Dentistry points out that young children often swallow toothpaste when they brush their teeth. The group notes that swallowing fluoridated toothpaste can cause problems. So young children should be carefully supervised when they brush their teeth. And only a small amount of fluoridated toothpaste,the size of a green pea,should be used. Parents often wonder what effects sucking a thumb or sucking on a pacifier might have on their baby's teeth. Dental experts generally agree that this is fine early in life. The American Academy of Family Physicians says most kids stop sucking their thumbs by the age of four. If it continues,the group advises parents to talk to their child's dentist or doctor. It could influence the correct development of permanent teeth.
Ans: Question: The boy with a bad tooth died because _ .Options:A his tooth disease was very deadlyB the doctor refused to treat him properlyC he didn't receive timely treatmentD something was wrong with his brainAnswer:C
