Ques:Read the following article and select the best answer. Article: People talk about energy everywhere. Green energy, for example. Then, energy independence. It has a nice ring to it. Doesn't it? If you think so, you're not alone, because energy independence has been the dream of American president for decades, and never more so than in the past few years, when the most recent oil price shock has been partly responsible for kicking off the great recession . "Energy independence" and its rhetorical companion "energy security" are, however, unreliable concepts that are rarely thought through. What is it that we want independence from, exactly? Most people would probably say that they want to be independent from imported oil. But there are reasons that we buy all that oil from elsewhere. The first reason is that we need it to keep our economy running. Yes, there is a trickle of biofuel available, and more may become available, but most biofuels cause economic waste and environmental destruction. Second, Americans have basically decided that they don't really want to produce all their own oil. They value the environmental quality they preserve over their oil imports from abroad. Vast areas of the United States are off-limits to oil exploration and production in the name of environmental protection. To what extent are Americans really willing to tolerate the environmental influence of domestic energy production in order to cut back imports? Third, there are benefits to trade. It allows for economic efficiency, and when we buy things from places that have lower production costs than we do, we benefit. And although you don't read about this much, the United States is also a large exporter of oil products, selling about 2 million barrels of petroleum products per day to about 90 countries. There is no question that the United States imports a great deal of energy and, in fact, relies on that steady flow to keep its economy stable. When that flow is interrupted, we feel the pain in short supplies and higher prices. At the same time, we get massive economic benefits when we buy... Question: What is the author's purpose in writing the passage? - To explain the increase of international oil trade. - To raise Americans' awareness of the energy crisis. - To argue for America's dependence on oil imports. - To stress the importance of energy protection.

Ans:To argue for America's dependence on oil imports.

Ques:Read the following article and select the best answer. Article: It was a quiet village in which there was a military camp . It was far from the towns and cities and there were some high mountains around. Of course it was a good place for training the new soldiers. But it was difficult for the young men to go outside. Mr. White, an officer of forty, was strict with them and he hardly let them leave the camp. Once Mr. White was ill in bed. He couldn't work and a young officer, Mr. Hunt began to train the new soldiers instead of him. He knew the young men well and let nine soldiers go to the nearest town to have a holiday. But night fell and none came back to the camp. He was worried about it and stood at the gate. It was five to twelve when Mr. Hunt decided to go to the town and see what was happening to the young men. He started the car quickly and set off. At that moment the nine soldiers came back. It seemed they drank wine. Of course they found the officer was angry. "I'm sorry, sir,"said the first soldier."I left the town on time. But something was wrong with my bus on my way here.

He said, "I'm sorry, sir. I got on a bus on time, but..." Having heard this, the officer became even angrier and stopped him at once.

Question: Which answer do you think is true? - You'll believe only the last soldier. - The officer believed the nine soldiers. - You'll believe none of the nine soldiers. - The officer won't punish his soldiers.

Ques:Read the following article and select the best answer. Article: Animals are being killed by hunters in America in a cruel way, says an animal protection organization. There are about 1,000 hunting farms across America whose owners offer hunters an opportunity to kill animals that are kept in fenced areas. Russian boar, zebra, deer, antelope and many other species are raised just to be killed. Farm owners charge hunters thousands of dollars for animals that they kill, many of which are close to extinction . The Humane Society of the United States says this type of hunting should be stopped because it is not fair to the animals. Many owners raise their animals. Others buy from animal dealers or from zoos and circuses that no longer want them. This means that the animals are not afraid of humans and they are easy to be shot by hunters. Owners of small ranches keep their animals in fenced areas so that the hunters can get close to the animals before shooting at them. On large farms hunters are taken to areas where the animals are fed sometime of the day. This also makes it easy to kill the animals. The hunters want to keep the heads and chests of the animals they kill to hang as trophies on their walls. This means that the animals are usually shot in parts of the body. That means they will suffer a slow and painful death. The hunting is allowed across most of America but some parts of the country have stopped or restricted it. The Humane Society of the United States hopes that it won't be too long before the rest parts of the country also give up this cruel sport. Question: It can be inferred from the passage that _ . - no measures have been taken to prevent this kind of hunting - the animals usually get really hungry before dying - in most parts of America this kind of hunting has been stopped - people who do this kind of hunting are probably very rich

Ans:
people who do this kind of hunting are probably very rich
