Q: Write a multi-choice question for the following article: Article: A recently study found people's lives are made shorter in North China. It is showed the life expectancy had been cut down by 5.5 years there. Researchers think that the heavy air pollution in China should be to blame . It's really the truth. Our government has already done something. However, it doesn't seem to work so well. "Air pollution in China is doing harm to people's health. The harm is much more serious than we can imagine," said Chen Yuyu of Beijing University, one of researchers of this study. Dirty air brings serious problems in North China. In January this year, the air pollution was worse than that in other places. That was caused by rising temperature and waste gas from coal heating. Chinese government should strongly fight against air pollution. They should think of more proper ways to deal with the problem. People should be encouraged to take buses, ride bicycles or walk, instead of driving cars. The factories that pollute heavily should be closed. "We need to improve our environment, although it might be expensive. Protecting our environment means protecting ourselves," Li Hongbin, another researcher of the study said.
A: Question: What's the main idea of the passage?Options:A Air pollution in North China is caused by waste gas.B To save the environment, our government should do something more.C The temperature becomes higher and higher in North China.D How air pollution in North China is caused.Answer:B

Question: Write a multi-choice question for the following article: Article: Using tablet computers like Apple's iPad and Samsung's Galaxy Note just before bed can lead to a poor night's sleep, according to research. More and more people are taking their tablets to bed with them to surf the web, check Facebook or email before switching off the light. But researchers are warning that the blueish light their screens emit can stop users getting a good night's sleep. That is because this type of light mimics daylight, convincing the brain that it is still daytime. Blue light suppresses production of a brain chemical called melatonin, which helps us fall sleep. This is because our brains have evolved to be wakeful during daylight hours. By contrast, light which is more orange or red in tone does not reduce melatonin production, perhaps because our brains recognize it as a cue that the day is ending. Neurologists have known for years that staring at screens late in the evening can disrupt sleep. Researchers at the Lighting Research Centre, at the Rensselaer Polytechnic Institute in New York, are warning that looking at tablet displays for more than two hours "leads to a suppression of our natural melatonin levels as the devices emit optical radiation at short wavelengths" - in other words, they emit bluer light. They say: "Although turning off devices at night is the ultimate solution, it is recommended that if these devices are used at night displays are dimmed as much as possible and that the time spent on them before bed should be limited." They drew their conclusions after measuring melatonin levels in 13 volunteers, after they had spent time viewing iPads at full brightness at a distance of 10 inches, for two hours. Melatonin levels were significantly lower after they had done this, than they were after the volunteers had viewed their iPads for the same time, but while wearing orange glass goggles, which cut out the blue light. They wrote in the journal Applied Ergonomics that tablet makers could "tune the spectral power distribution of self-luminous devices " so that they...
Answer: Question: What is it that stops users getting a good night's sleep?Options:A ScreensB blueish lightC MelatoninD Orange or red lightAnswer:B

[Q]: Write a multi-choice question for the following article: Article: Many of us believe that a person's mind becomes less active as he grows older.But this is not true,according to Dr.Lissy F.Jarvik,professor of psychiatry at the University of California,Los Angeles,and a board member of the New Center for Aging at the Veterans Hospital.She has studied the mental functioning of aging persons for several years.For example,one of her studies concerns 136 pairs of twins, who were first examined when they were already 60 years old.As Dr.Jarvik continued the study of the twins into their 70s and 80s,their minds did not generally decline as was expected. However,there was some decline in their psycho-motor speed. This means that it took them longer to accomplish mental tasks than it used to.But when speed was not a factor,they lost very little intellectual ability over the years.In general,Dr.Jarvik's studies have shown that there is no decline in knowledge or reasoning ability.This is true not only into the 30s and 40s,but into the 60s and 70s as well. As for learning new things,and ability to remember,studies by Dr.Jarvik and others show that the old are equal to the young.It is true that older people themselves often complain that their memory is not as good as it once was.However,much of what we call"loss of memory"is not that at a11. In the cases where the older person's mind really seems to decline,it is not necessarilv a sign of a decay due to becoming old or"senility".Often it is simply a sign of a depressed emotional state.This depression usually can be got rid of by counseling with a psychologist,or medicine which fights depression. In American society,when an older person loses something,we tend to call him or her"senile".But notice that when a younger person loses something,he does not blame it on senility or loss of memory.He finds some other excuse!

[A]: Question: The word"senility"most likely means_.Options:A excellent healthB weakness in body and mind because of old ageC occasional forgetfulnessD giving up one's lifeAnswer:B

Question: Write a multi-choice question for the following article: Article: When did you see a polar bear ? On a trip to a zoo, perhaps ? If you had attended a winter activity in New York a few years ago, you would have seen a whole polar bear club. These "Polar Bears" are people who meet frequently in the winter to swim in freezing cold water. That day, the air temperature was 3 degrees. And the water temperature was a little higher. The members of the Polar Bear Club at Coney Island, New York are usually about the age of 60. Members must satisfy two requirements. First, they must get along well with everyone else in the group; this is very important because there are so many different kinds of people in the club. Polar Bears must also agree to swim outdoors at least twice a month from November through February. Doctors don't agree about the medical effects of cold-water swimming. Some are worried about the dangers of a condition in which the body's temperature drops so slow that finally the heart stops. Other doctors, however, point out that there is more danger of a heart attack during summer swimming because the difference between the air temperature and the water tempreature is much greater in summer than in winter. The Polar Bears themselves are satisfied with the benefits of cold-water swimming. They say that their favorite form of exercise is very good for the circulatory system because it forces the blood to move fast to keep the body warm. Cold-water swimmers usually turn bright red after a few minutes in the water. A person who turns blue probably has a very poor circulatory system and could not try cold-water swimming. The main benefits of cold-water swimming are probably mental. The Polar Bears love to swim all the year round; they find it fun and relaxing. As one 70-year-old woman says, "When I go into the water, I pour my troubles into the ocean and let them float away."
