I'm taking a test and have to guess the right answer to the question after the article. Article: Animals are natural resources that people have wasted all through our history. Animals have been killed for their fur and feathers, for food, for sport, and simply because they were in the way. Thousands of kinds of animals have disappeared from the world forever. Hundreds more are on the danger list today. About 170 kinds in the United States alone are considered in danger. Why should people care? Because we need animals. And because once they are gone, there will never be any more. Animals are more than just beautiful and interesting. They are more than just a source of food. Every animal has its place in the balance of nature . Destroying one kind of animal can create many problems. For example, when farmers killed large numbers of hawks , the farmers' stores of corn and grain were destroyed by rats and mice. Why? Because hawks eat rats and mice. With no hawks to keep down their numbers, the rats and mice multiplied quickly. Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger. Quite a few countries have passed laws. These laws forbid the killing of any animals or plants on the danger list. Slowly, the number of some animals in danger is growing. Question: Animals are important to us mainly because _ . Options: A: they give us a source of food B: they are beautiful and lovely C: they keep the balance of nature D: they give us a lot of pleasure

I'm taking a test and have to guess the right answer to the question after the article. Article: My 3-year-old son and I lived a very hard life because I had been out of work since two years ago. Being poor is a terrible feeling when your 3-year-old finishes his meal and says: "Can I have some more bread and jam please, Mummy?" And you break down in tears, because you don't know how to tell him that there is no more food. With PS6, I went to the supermarket, picked up some food and started to cook at home. It was time for me to make a change and get back on my feet. I began to write a series of articles for the website named Hunger Hurt in July 2011. A few months later, local food bank gave me some help-- with some free vegetables every month, which made my life a little easier. I began to write recipes , posting them on my blog. To my surprise, families, students and those poor people told me how much it helped to see healthy recipes made from affordable supermarket vegetables. My Life took unexpected turns. I was invited to give a speech on food , interviewed for an Oxfam report on food banks and asked to write a cookery book. When I got the money from the book, for the first night in almost two years, I went to bed without worrying. Now, I have a well-paid job and a beautiful home, and I'll never forget the days when I worked hard for a good life. Question: The writer started to cook because _ . Options: A: the food at the supermarket was unhealthy B: she had to feed themselves in a cheap way C: she was advised to do so by someone D: her son preferred home-cooked food

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: "Indeed," George Washington wrote in his diary in 1785, " some kind of fly, or bug, had begun to eat the leaves before I left home. " But the father of America was not the father of bug. When Washington wrote that, Englishmen had been referring to insects as bugs for more than a century,and Americans had already created lightning-bug .But the English were soon to stop using the bugs in their language, leaving it to the Americans to call a bug a bug in the nineteenth and twentieth centuries. The American bug could also be a person, referring to someone who was crazy about a particular activity. Although fan became the usual term, sports fans used to be called racing bugs, baseball bugs, and the like. Or the bug could be a small machine or object, for example, a bug-shaped car. The bug could also be a burglar alarm, from which comes the expression to bug,that is,"to install an alarm". Now it means a small piece of equipment that people use for listening secretly to others' conversations. Since the 1840s,to bug has long meant" to cheat" , and since the 1940s it has been annoying. We also know the bug as a _ in a computer program or other design. That meaning dates back to the time of Thomas Edison. In 1878 he explained bugs as"little problems and difficulties" that required months of study and labor to overcome in developing a successful product. In 1889 it was recorded that Edison" had been up the two previous nights discovering' a bug' in his invented record player." Question: The passage is mainly concerned with _ . Options: A: the misunderstanding of the word bug B: the development of the word bug C: the public views of the word bug D: the special characteristics of the word bug
A: B

I'm taking a test and have to guess the right answer to the question after the article. Article: Imagine putting some bacteria in the freezer and taking them out millions of years later to find that they are still alive. That would be similar to what happened recently, when scientists brought eight-million-year-old bacteria back to life -- simply by thawing them out. The ancient bacteria were found frozen in the world's oldest known tracts of ice, the glaciers of Antarctica. Professor Bidle and his colleagues found and revived two samples of bacteria from the glacial ice. The first was a hundred thousand years old, and the second was around eight million years old. The eight-million-year-old bacteria were alive. But their genes were seriously damaged from long exposure to cosmic ( ) radiation, which is higher at the earth's poles. Most of the bacteria in the samples probably blew over from African deserts, said Paul Falkowski, a scientist at prefix = st1 /RutgersUniversity. Once the bacteria landed on the glacier's snowy surface, they combined with the snow to form ice. "These ices are actually gene banks," he added. As glaciers and ice caps melt as a result of increasing global warming, large amounts of bacterial genetic material might be washed into the ocean. These bacteria might get incorporated into today's bacteria in the ocean, or living bacteria from the ice might also grow and have an important effect on the ecosystem. "How that's going to play out, we don't know," Bidle said. He and Falkowski plan to focus their future work on how current ice melting influences modem bacteria's genetic diversity. Question: According to Paul Falkowski, the ices in Antarctica are gene banks because _ . Options: A: there are bacteria from African deserts B: dead bacteria in them can be easily revived C: they are fit for people to store bacteria D: plenty of living bacteria can be found in them
