I'm taking a test and have to guess the right answer to the question after the article. Article: So far, scientists have named about 1.8 million living species ,and that's just a small part of what probably exists on Earth.With so many plants,animals,fungi,and other organisms covering the planet,it can be tough to figure out what type of spider is crawling up your leg or what kind of bird just flew by. A soon-to-be-launched Website might help.An international team of researchers has announced the creation of a Web -- based Encyclopedia of Life (EOL).The project aims to catalogue every species on Earth in a single,easy-to-use reference guide. To get the encyclopedia started,the creators will use information from scientific databases that already exist.And eventually,in special sections of the site,nonscientists with specialized knowledge will join.Gardeners,for example,will be able to record the dates that their flowers first bloom each year.Bird-watchers will be able to input which birds they've seen and where.The technology for this kind of tool has only recently become available. As the EOL develops, you might find it useful for school projects.The site will have special pages for kids who are studying ecosystems in their neighborhoods.To make sure the encyclopedia is accurate,scientists will review much of the information added to it.People who visit the site will be able to choose to skip pages that haven't been reviewed. Another convenient characteristic of the EOL is that you'11 be able to pick the level of detail you see to match your interests,age,and current knowledge. If you wanted to learn about polar bears for a science class report,for example,you could use the _ setting to get basic information about the animals.On the "expert" setting,on the other hand.you could get much more detailed information about the history,literature,and exploration of polar bears. It now takes years for scientists to collect all the data they need to describe and analyze species.The creators of the Encyclopedia of Life hope that their new tool will speed that process. Keep an eye on _ .Pages will begin to... Question: What is the best title for the passage? Options: A: Exploring Polar Bears. B: Visit Our Website Now. C: How to Do School Projects. D: E-book of Life.

I'm taking a test and have to guess the right answer to the question after the article. Article: When I was at university, I studied very hard. But a lot of my friends did very little work. Some did just enough to pass exams. Others didn't do quite enough. Fred Baines was one of them. He spent more time drinking in the Students' Union than working in the library. Once, at the end of the term, we had to take an important test in chemistry. The test had a hundred questions. Beside each question we had to write "True" or "False". While I was studying in my room the night before the test, Fred was watching television. Fred usually worried a lot the night before a test. But that night he looked perfectly calm. Then he told me of his plan. "It's very simple. There are a hundred questions and I have to get fifty correct to pass the test. I'll take a coin into the examination room. I haven't studied a chemistry book for months, so I'll just toss the coin. In that way, I'm sure I'll get half the questions right." The next day, Fred came cheerfully into the examination room. As he sat tossing a coin for half an hour he marked down his answers. Then he left half an hour before the rest of us. The next day, he saw the chemistry professor in the corridor. "Oh good," he said, "Have you got the results of the test?" The professor looked at him and smiled. "Ah, it's you, Baines, just a minute." Then he reached into his pocket and took out a coin. He threw it into the air, caught it in his hand and looked at it. "I'm terribly sorry, Baines," he said, "You failed!" Question: According to the text, we can know working hard is _ . Options: A: unnecessary B: valuable C: useless D: a waste

I'm taking a test and have to guess the right answer to the question after the article. Article: A recent study suggests that teens' relationship with parents, friends and teachers may have a lot to do with why they don't get a good night's sleep. David Maume, a sociologist and sleep researcher, analyzed federal health data, which interviewed 974 teenagers when they were 12, and then again at 15. He found that family dynamics have much to do with how well kids sleep. Teens, who had warm relations with their parents and felt like they could talk to them or their parents were supportive of them, tended to sleep better. However, families that were going through a divorce or a remarriage tended to affect teens' sleep. And problems at school also affected teens' sleep. Feeling safe at school and having good relations with teachers tended to promote better sleep. As did good relationships with friends. Kids who took part in sports or other positive social activities or shared similar academic goals with their friends were also more likely to get a good night's sleep. These add up to what makes lots of sense: a general feeling of well-being helps teens sleep. If we're happy and contented, we're much more likely to sleep better than if we're sad and anxious. Now, of course, teens can hardly resist being drawn to their computers and social networking. Maume also found that when parents were strict not only about bedtime, but also about limiting technology, kids slept better. It's a finding that seems obvious, but parents really do matter when it comes to health habits of their teenagers. Clearly, teenagers aren't getting 9 to 10 hours a night, which puts them at risk for all the consequences of lack of sleep, including poor academic performance, colds and stress. Question: Parents are supposed to _ when their kids are growing up. Options: A: continue their broken marriage B: allow children to decide when to sleep C: limit teens' using new technology D: force teens to have 10 hours' sleep daily
