Problem: Write a multi-choice question for the following article: Article: What will power your house in the future? According to scientists at the Massachusetts Institute of Technology (MIT) in the US, it might be artificial leaves. Natural leaves can change sunlight and water into energy. It is known as photosynthesis . Now researchers have found a way to imitate this process. The artificial leaf developed by Daniel Nocera and his colleagues at MIT can be seen as a special silicon chip with catalysts . Similar to natural leaves, it can split water into hydrogen and oxygen when put into a bucket of water. The hydrogen and oxygen gases are then stored in a fuel cell, using those two materials to produce electricity, located either on top of a house or beside the house. Though the leaf is shaped like a poker card, scientists stated that it is promising to be an inexpensive somtoe of electricity in developing countries. "One can imagine villages in India and Africa not long from now purchasing an affordable basic power system based on this technology," said an American scientist, Docera. An artificial leaf is not a new idea. The first artificial leaf was invented in 1997 but too expensive and unstable for practical use. The new leaf, however, is made of cheap materials, easy to use and highly stable. In laboratory studies, Nocera showed that an artificial leaf could operate continuously for at least 45 hours. The wonderful improvements come from Nocera's recent discovery of several powerful new, inexpensive catalysts. These catalysts make the energy transformation inside the leaf more efficient with water and sunlight. Right now, the new leaf is about 10 times more effective at carrying out photosynthesis than a natural one. Besides, the device can run in whatever water is available. Hopefully, each home could possible have the access to the new application in the future.

A: Question: What conclusion can be drawn from the text?Options:A Docera thought the new leaf is expensive for developing countries.B Villages in Africa have benefited a lot from the new invention.C Silicon chip can help the new leaf work more effectively.D The equipment doesn't necessarily operate in pure water.Answer:D

Problem: Write a multi-choice question for the following article: Article: The organization representing British universities has expressed concern about the potential effect of tuition fees after figures showed a drop of more than 6% in student applications with less than a month to go before the deadline for 2013 applications. Data from the Universities and Colleges Admissions Service (Ucas) showed there were 265,784 university applications by UK-based candiates up to 17 Decemeber, 6.3% down on the parallel period in the admissions cycle the year before. While this is less than the 8.4% year-on-uear fall seen in earlier Ucas figures, released in mid-November, the coming January deadline makes it ever more likely that the total 2013 applicant figure will see a second sizeable fall following the introduction of annual fees of up to PS9,000. Nicola Dandridge, the chairman of Universities UK, said : "However, we must be concerned about any drops in the numbers applying to university and in particular, we must look closely at how the increase in graduate contributions in England may be affecting the decisions of promising students. However ,the December figures show a drop in numbers across the UK, suggesting that it is not only a question of tuition fees in England putting off from applying." A report of the Uncas figures to mid-December shows a 6.5% fall for applicants in England and 11.7% for those in Wales, with smaller drops of 3.9% for Scotland and 0.5% for Nortern Ireland. Scotiish students at home insitiutions pay on fees, while those from Nothern Ireland have fees capped to PS3,575 for Northern Irish universities. Dandridge added: "No one should be put off applying to university because of worries about finance." "It is important that no one is put off applying to university because they do not have information about the student support available to them. Most new students don't need to pay directly. There will be more financial support for those from poorer families and everyone will make lower loan repayments thatn they do now once they are in well paid jobs."

A: Question: A drop of more than 6% for 2013 applications is probably the effect of _ .Options:A the increased tuition feesB the approaching deadlineC the concern from applicantsD the difficulties with applicationsAnswer:A

Problem: Write a multi-choice question for the following article: Article: An affordable housing law passed three years ago promises a possible supply of below-market-rate homes, but has failed to encourage increased housing production and is unlikely to affect prefix = st1 /San Francisco's poorest families. Barbara, 44, who came to The City in 1970, have been trying to pick herself up from the bottom, where she and her children started out with just the clothes on their backs-through the kindness of others they got by. They were last homeless in 1999. Since then, Barbara has worked hard to keep from returning to the streets and the shelters, taking advantage first of transitional housing, then a rent assistance, and studying for a job as a nursing assistant and a home health aide. However the cost for housing has made it difficult for her to _ . She can't afford proper housing. Even an improper shelter costs as much as $ 1,200 for rent. She has to spend every night in a dining room. In this respect, she is not alone. There are hundreds of thousands of San Franciscans who are in the same boat with her. Since 2000, she's been providing health care in the homes of charity , and relying on an assistance program to pay the rent for her two-bedroom apartment in the Lower Height. A few months ago she lost her full-time job due to budget cuts, just as she had hoped to get a permanent post that would allow her to cover her $ 1,700 monthly rent. Now she works three or four hour shifts six days a week for $ 10.50 an hour, taking the bus around from client to client and worrying that in February, when her rent assistance is gone, she could end up on the streets with her family again.

A: Question: The passage suggests that _ .Options:A Barbara would be homeless againB Barbara is a lazy personC Barbara could not live without helpD Barbara is out of work nowAnswer:C

Problem: Write a multi-choice question for the following article: Article: Health experts have long worried about the increasing rate of obesity in kids. It's an important concern: Being weight or obese during childhood can lead to serious problems normally seen in adults, such as diabetes and high blood pressure. Poor diets and a lack of exercise are usually the causes. But would you ever have imagined there might be a connection between the bacteria that lived in your guts when you were a baby and the chance that you would become overweight? Scientists in Finland recently found just such a link. In a recent study, they showed that overweight kids had different species of bacteria living in their guts. You probably think of bacteria only as germs that can make you sick. While it's true that some bacteria can make people ill, your body actually depends on some types of bacteria to help you digest food and extract nutrients from it. These "good" bacteria live in your guts, where they process the food you eat. Human babies get these bacterial helpers from their moms. When a baby is born, some of the bacteria in the mother move into the baby's body. Growing babies get additional "good" bacteria from the milk their mothers produce. And it turns out the bacteria might play an important role in regulating weight just six years later. So how could these bacteria affect weight? The researchers still haven't tested that question, but future tests might lead to an answer.

A:
Question: The purpose of writing this passage is to _ .Options:A introduce the role of bacteria in children's weightB analyze the influence of obesity on kidsC give advice on how to lose weight quicklyD explain the function of bacteria in foodsAnswer:A
