Question: I'm taking a test and have to guess the right answer to the question after the article. Article: London--coffee protects mice from radiation and could get the same way in humans, according to Indian scientists. Scientist at India's Bhabha Atomic Research Center discovered that mice injected with caffeine remained alive after high doses of normally _ radiation. Although the study was limited to animals, Kachadillilli George, head of the research team, believes the findings could have implications (something suggested ) for humans . "It does suggest that coffee might have some beneficial effects in protecting against radiation," he told New Scientist magazine late last month. George and his team injected 471 mice with caffeine and left them uncovered to 7.5 grays of gamma radiation ,enough to kill most mice. But 25 days later 70 percent of the mice that had received 80 milligrams of caffeine per kilogram of body weight were still alive. On the contrary all 196 mice that had been left uncovered to the same radiation but had not been given any caffeine died. Question: George and his team drew the conclusion from _ . Options: A: the magazine B: their invention C: the experiment D: their experience
Answer: C

Question: I'm taking a test and have to guess the right answer to the question after the article. Article: A "blogger" is a person who writes on an Internet computer Web site called a "blog". The word "blog" is a short way of saying Web log, or personal Web site. Anyone can start a blog, and they can write about anything they like. There are millions of blogs on the Internet today. They provide news, information and ideas in many people who read them. They contain links to other Web sites. And they provide a place for people to write about their ideas and react to the ideas of others. A research company called Perscus has studied more than 300 Web logs. It says that blogs are most popular with teenage girls. They use them to let their friends know what is happening in their lives. The study also says that more than 100,000 bloggers stopped taking part in the activity after a year. However, some people develop serious blogs to present political and other ideas. For example, the Republican and Democratic parties in the southern state of Kentucky recently started their own blogs. And American companies are beginning to use blogs to advertise their products. At the same time, some long-standing blogs have ended last week, blogging leader Dave Winer closed his free blog service weblogs. com. He says the site became too costly to continue. He started the blog four years ago. And thousands of people had written on it. They are now upset because they did not know that the site was closing. One blog that is still going strong is called Rebecca's Pocket. Rebecca Blood created the Website in 1999. She wrote about the history of blogs on the site. That article led to a book called "The Weblog Handbook". It has been translated into four languages so far. Ms. Blood says Rebecca's Pocket gets about 30,000 visitors a month. She writes about anything and everything--politics, culture and movies. She recently provided medical advice. And she wrote about how to prevent people from stealing money from on-line bank accounts. Question: From the text we can learn that blogs cover almost everything except _ . Options: A: different ideas B: medical advice C: advertisements D: account passwords
Answer: D

Question: I'm taking a test and have to guess the right answer to the question after the article. Article: The Internet has greatly changed the way people communicate. But some teachers think the changes are not all for the better. Eleanor Johnson, an English professor, thinks that text messaging has made students believe that it is far more acceptable than it actually is to just make terrible spelling and grammatical errors. And she says her students over the past several years have increasingly used less formal English in their writing. Words and phrases like "guy" and "you know" now appear in research papers. Professor Johnson supposes there is a strong relationship between the rise of informal online communication and an increase in writing mistakes. But she says there may not be much scientific information, at least not yet. David Crystal, a British linguist , says the actively changing nature of the Internet makes it difficult to keep up-to-date in studying its effects. But he believes its influence on language is small. The main effect of the Internet on language is the way it has added to the expressive richness of language, providing language with a new set of communicative tools that haven't existed in the past. Erin Jansen is founder of NetLingo.com, an online dictionary of the Internet and text messaging terms. She says the new technology has not changed existing language but has greatly added to its vocabulary. Basically it's freedom of expression. And what about those teachers who find these new kinds of mistakes in spelling and grammar in their students' work? What is her message to them? Erin Jansen said, "I am always on the students' side and won't get angry or upset about that. If it's helping the kids write more or communicate more, that's great. That's what teachers and educators want--to get kids communicating." But Erin Jansen and David Crystal agree with Eleanor Johnson on at least one thing. Teachers need to make sure students understand the uses and rules of language. Question: The author wants to tell us that _ . Options: A: different opinions on informal expressions exist B: what language is now used on the Internet C: informal expressions are popular among teachers D: why the Internet is welcomed by all students

A
