Write a multi-choice question for the following article: Article: Tsunami is a natural disaster, which is a Japanese word that means "sea wave". A tsunami is a huge sea wave that forms mainly in the Pacific Ocean area. People die and property is destroyed when a tsunami hits land. What causes these dangerous sea waves? Sometimes, tsunamis are caused when earthquakes take place underwater. Then, water begins to move up and down from the top of the ocean right down to the bottom. Waves begin to form, and each wave is called a tsunami. A tsunami is less than one meter high and can move at a speed of almost 800 kilometers per hour while it is far out in the ocean. But the tsunami rises much higher and moves more slowly as it comes closer to land. The weather bureau warns people over the radio and television when a tsunami is heading for land. These warnings have helped save many lives.
Ans: Question: As the tsunami moves toward land, it _ .Options:A picks up more speedB becomes far less dangerousC rises higher and higherD rises lower and lowerAnswer:C

Write a multi-choice question for the following article: Article: Having a great collection of books at home doesn't really mean that you are a person who loves reading. It may be got from your father or your father's father, and it can just impress people around you with the fact that you are a person of culture. From my point of view, reading is very important in our daily life. For example, reading is a way of gaining knowledge in different areas. It can help us have a great imagination, and it makes things easier when it comes to making compositions on different themes. It gives you the possibility to speak about science, even if you don't work in this field. You can express your opinions about a political event because you have read something about that. Secondly, reading gives us the possibility to enter the world of imagination. We can imagine what life will be like in the future. Sometimes, we compare ourselves with the people in the stories we read and they can give us some clues to solve the problems and tell us what to do in certain situations. Books are based on real life. Even if writers are considered to be somehow different from common people, they often face the same problems as we all do. In short, I would like to say that literature is the perfect way of enriching our culture, expressing correctly, having a rich vocabulary, being able to understand different fields and really being considered to be a learned person.
Ans: Question: What can be the best title for the text?Options:A Why Is Reading Important in Our LifeB How Can We Become a Learned PersonC Different Reading, Different FunctionsD Having a Good Collection of Books Means a LotAnswer:A

Write a multi-choice question for the following article: Article: Boys and girls,as we all know,most people,especially young people ,tend to care about their hair much because hair plays a very important role in our appearance.But can you imagine what other uses hair has?Do you have any idea that human hair may become a new solar energy soutce?Before we begin with the new content of our Physics ,let me tell you a new invention first. It's reported that a Nepali teenager has designed a $32 solar panel using human hair. Milan Karki,who is 18 years old and lives in a village in rural Nepal,used human hair to replace silicon ,which is a common but expensive componet of solar panels. By using hair as a replacement,Karki says that solar panels can be produced for around $32,a price that could be halved if they were mass-produced. The solar panel works,because melanin ,which gives hair its colour,is light sensitive and can act as an elecrtical conductor.Kaiki was inspired to think of the idea by a Stephen Hawking book ,which explained how to create elecrtic energy from hair. The device that Karki has invented is capable of producing 9V or 18V of energy--plenty to charge a mobile phone. "Half a kilo of hair can be bought for only 16p in Nepal and lasts a few months;whereas a pack of batteries would cost50p and lasts few nights,"according to The Daily Mail. The solar panel is claimed to be easy to service as the hair is easy to replace. Karki has now seng out several devices to other disrticts near his home for tetimg .He said,"First I wanted to provide elecricity for my home,then my village .Now I am thinking for the whole worle." So next time when you have a haircut,do remember to keep your hair cut down to use for energy.Perhaps you can also provide elecrticity for your home,even your village using your own hair.
Ans: Question: Which of the following is true about Milan Karki?Options:A He is good at his study.B He hasn't been to a big city.C He is a man good at thinking.D He has earned much money from his invention.Answer:C

Write a multi-choice question for the following article: Article: Store shelves are filling up with so-called "green" products promising to benefit the environment. A recent argument shows that it can be as difficult for buyers to confirm such statement as for producers to defend them. The argument concerns the GreenPlug Electricity Saver. The GreenPlug is supposed to prevent energy waste by electrical equipment whose constant -speed motors operate at less full load---as is especially true of older refrigerators. Research showed that such motors can be made to do the same work with less heat, noise, and power consumption just by lowering the voltage of the power supply. John and Wyck Hay, started Green Technologies to apply that finding to home appliances. In the USA, there are more than 140 million refrigerators in use, accounting for an average of 16% of the household electric bill. Two years of research resulted in the GreenPlug. Connecting between wall socket and refrigerator, the equipment contains a minicomputer that gives a motor full power (120 volts on average) for start-up, then reduces the power to 106 volts. Older refrigerators are the most overpowered and, thus, save the most energy with a GreenPlug. Refrigerators less than two years old are already energy-saving that a GreenPlug actually makes them waste electricity. The higher the voltage, the larger the difference a GreenPlug makes. Higher power costs shorten the payback time. The population-weighted national average is 10 cents per kilowatt-hour. But some residents in Washington State pay 1.5 cents. Some in Alaska pay 41.6 cents. Then come highly individual household differences like the number of children or refrigerator -opening age. All in all, the GreenPlug should save the average consumer $20 a year. Although the GreenPlug lowered the voltage as it was designed to do,Consumer Reports, an influential magazine, questioned how quickly---if ever---electricity savings due to the plug would repay its cost. People would be better off buying a new, high-efficiency refrigerator, the magazine...
Ans: Question: We can infer from the passage that the author _ .Options:A feels optimistic about the future of GreenPlug.B believes the GreenPlug has cheated customers.C holds an objective attitude to the issue.D encourages further investigation.Answer:C
