I'm taking a test and have to guess the right answer to the question after the article. Article: Thomas Jefferson, the third president of the United States, was a good and tireless writer, and he wrote The Declaration of Independence. There is much we can learn from him. Here are some of the things he said and wrote: Go and see. Jefferson believed that a free man obtains knowledge from many sources besides books, and personal investigation is important as well. Judge for yourself. Jefferson refused to accept other people's opinions without careful thought. "Neither believe nor reject anything," he wrote to his nephew. Learn from everyone. Jefferson once visited the French nobleman, Lafayette, and said to him, "You must go into the people's home as I have done ,look into their cooking pots and eat their bread. If you will only do this, you may find out why people are dissatisfied. " Do what you believe is right. In a free country, there will always be conflicting ideas, and this is a source of strength. It is not unquestioning agreement but conflict that keeps freedom alive. Though Jefferson was for many years the object of strong criticism, he never answered his critics. He expressed his philosophy, "There are two sides to every question. If you take one side with decision and act on it with effect, those who take the other side will of course resent your actions. " Trust the future and trust the young. Jefferson felt that the present should never be chained to customs which have lost their usefulness. "The earth belongs to the living generation. " He didn't fear new ideas, nor did he fear the future. "How much pain has been caused by evils which have never happened?" he remarked,"I expect the best, not the worst. " Question: The author mentioned Jefferson's visit to Lafayette to show _ . Options: A: Jefferson was dissatisfied with Lafayette B: Jefferson had a close relationship with his people C: Jefferson was a great American president D: Jefferson valued the importance of learning from others

I'm taking a test and have to guess the right answer to the question after the article. Article: When a handheld video game runs out of power, all you have to do is plug it in and charge it up. Within a few years, some of you might do the same thing with mom's car. Automobile companies are developing vehiclesthat will plug into electricsockets , just like many laptops, digitalcameras, cell phones and small video game players do. Called "plug-inhybrids ," these cars will get most of their power from electricity. Their drivers will rarely haveto stop at gas stations. The technology is more than just cool. In our automobile-filled world, plug-in vehicles could reduce the amount of gasoline we use. That gas is made from crude oil, which has been kept rising in cost. Plus, driving around in these hybrids may even help the environment. Gas-burning cars produce a lot of carbon dioxide, a type of greenhouse gas. These gases stay in the atmosphere, where theytrapheat and cause global warming. The first company-produced plug-in hybrids could hitthe roads by 20l0. But engineers still have a lot of work to do to make the technology practical and inexpensive. Batteries are the biggest challenge. In the plug-in-hybrid world, Li-ion batteries are getting the most attention. These batteries can store a large amount of energy in a small package, and they last a ly long time between charges. Li-ion batteries are standard in laptops, cell phones, heart devicesand similarportabledevices. But because cars are so big and heavy, it would still require a suitcase-sized Li-ion battery to power about l2km of driving. What's more, the batteries are extremely expensive. "A car filled with batteries could go a long distance," says Ted Bohn, an electrical engineer in prefix = st1 /Chicago. "But it couldn'thaul any people, and it would cost $l00,000." So researchers need to figure out how to make batteries smaller and cheaper, among other questions. "The answers don't exist yet," Bohn says. "As a kid I thought someone someplace knows the answer to everything. All of these questions haven't been decided. That's what... Question: From the passage, we can learn _ . Options: A: we can buy one of "plug-in hybrids" now B: all people will buy one after 20l0 C: this kind of car can carry two persons D: some problems about "plug-in hybrids" remain to be done

I'm taking a test and have to guess the right answer to the question after the article. Article: More and more birds are flying to settle at Qinghai Lake, one of the highest inland lakes in China, thanks to the protection efforts of local governments. Covering an area of over 4,000 square kilometers, Qinghai Lake is also the country's biggest salt-water lake. Located in Northwest China's Qinghai Province, the lake is famous for the two islands at its northwest point--Cormorant Island and Egg Island. The two islands have plenty of floating grass and various schools of fish, offering rich food sources for birds. The islands have become a paradise for different kinds of groups of birds and have been called 'Bird Islands'. Each March and April, when ice and snow covering the Qinghai-Tibet Plateau starts to melt, over 20 kinds of birds fly to the Bird Islands to lay eggs. During the months, flocks of birds cover the whole sky over the islands and birds eggs can be found everywhere. Visitors can hear the singing of birds from miles away. These have become a world famous symbol of the lake. To protect this paradise for birds and support calls for ecological protection, China set up the Qinghai Lake Natural Protection Zone at the end of 1997. Meanwhile, the State has pointed out the Bird Islands and Spring Bay of the Qinghai Lake as central protection zones. Inspection officials and management employees often patrol the lake, improving local residents' knowledge of related laws and spreading knowledge about animal protection to visitors. They are making great efforts to call on people to love and protect the birds. At the same time, they have built special fences around the island area, to prevent wolves, foxes and other carnivorous animals, as well as illegal hunters from breaking up the birds' nest-building, egg-laying and breeding. As a result, more and more birds are coming to the islands for sheltering and breeding. Question: The officials go around the lake mainly to _ Options: A: let the farmers there know the animal protection law B: tell the farmers there some knowledge about animal protection. C: call on people to love and protect the birds D: all of the above
