Write a multi-choice question for the following article: Article: Legend has it that sometime toward the end of the Civil War (1861 - 1865) a government train carrying oxen was caught in a snowstorm and had to be abandoned. The driver returned the next spring to see what had become of his cargo. Instead of the skeletons he had expected to find, he saw his oxen, living, fat, and healthy. How had they survived? The answer lay in a resource that unknowing Americans had trampled underfoot in their haste to cross the "Great American Desert" to reach lands that sometimes proved barren. In the eastern parts of the United States, the preferred grass for forage was a cultivated plant. It grew well with enough rain, then when cut and stored it would cure and become nourishing hay for winter feed. But in the dry grazing lands of the west, that familiar blue joint grass was often killed by drought. To raise cattle out there seemed risky or even hopeless. Who could imagine a fairy-tale grass that required no rain and somehow made it possible for cattle to feed themselves all winter? But the surprising western wild grasses did just that. They had wonderfully convenient features that made them superior to the cultivated eastern grasses. Variously known as buffalo grass, not only were they immune to drought, but they were actually preserved by the lack of summer and autumn rains. They were not juicy like the cultivated eastern grasses, but had short, hard stems. And they did not need to be cured in a barn, but dried right where they grew on the ground. When they dried in this way, they remained naturally sweet and nourishing through the winter. Cattle left outdoors to fend for themselves thrived on this hay. And the cattle themselves helped plant the fresh grass year after year, for they trampled the natural seeds firmly into the soil to be watered by the melting snows of winter and the occasional rains of spring. The dry summer air cured them much as storing in a barn cured the cultivated grasses.
Ans: Question: According to the passage, the cattle helped promote the growth of the wild grasses by _ .Options:A stepping on and pressing the seeds into the groundB naturally fertilizing the soilC continually moving from one grazing area to anotherD eating only small quantities of grassAnswer:A

Write a multi-choice question for the following article: Article: Agricultural experts met in Ethiopia last week to discuss ways to help sub-Saharan Africa become a major producer of wheat. The area traditionally produced little wheat, while North Africa was the grain basket. Wheat production fell sharply in sub-Saharan countries during the 1980s. In the 1960s, attempts were made to grow wheat in sub-Saharan Africa, including South Africa and Zimbabwe. But those countries found it was less costly to import wheat from Europe and the United States. Another problem is that Africa's wheat farms were often far from population centers. There also were transportation issues. And some lowlands were not a good place to grow wheat. Hans Joachim Braun,one of the experts, says now is a good time to increase wheat production. In the last four years we have seen three major price hikes, where the wheat price and other staple process exploded. And that puts a big, big bill on countries which are depending on wheat imports, and Africa is the biggest wheat importer. He also says demand for wheat in sub-Saharan Africa is growing faster than for any other crop. With higher income people would like to have more diversified food. But that is possible not the most important one. The most important one is that there is a tremendous migration of in particular male labor to the cities. And wheat products are convenient food because you can easily buy it. It's easy to process and you also can store it for a few days, which is different from some of the maize and rice products. There are three possible challenges for growing more wheat in Africa: climate change, disease and pests, like insects. Mr. Braun says rising temperatures should not have a major effect on wheat. In fact, he says, it could help wheat grow in areas with high rainfall totals. As for fighting disease and pests, experts suggest growing more resistant crops. In addition, railroads and roads would have to be improved so large amounts of wheat could be moved to large markets.
Ans: Question: Wheat price exploding indicates _ .Options:A sub-Saharan countries need to increase wheat production badlyB sub-Saharan countries have to issue more moneyC sub-Saharan countries should grow more CornD importing much wheat is urgentAnswer:A

Write a multi-choice question for the following article: Article: One in five American families will move every year. Moving is one of the most stress-producing events a family has to go through. Experts say it can be harder for children. How do you help your child adjust to the changes? The Ricardos moved from their old house to a new home. Same family, same dog-but it was harder for 9-year-old Elena. She hated the room, the house and everything. She hated leaving her friends the most. " I was so emotional. I mean, saying goodbye to all my friends.....my very close friends, who was my neighbor, made me so sad," says Elena. For some children, the emotional stress of moving is not much more different from the emotions when someone has died. "There's that sense that, 'I've lost my friends, my friends, my base, my school, my teachers-everything I knew that made me feel safe is all gone now. I have to start over," says Dr. Tim Jordan. Starting over is exactly Dr. Tim Jordan's advice. Make new friends, enter the new school and enter the new neighborhood. And here are some other pieces of advice. * Explain clearly to the children why the move is necessary. * Familiarize the children as much as possible with the new area with maps, photographs or the daily newspaper. * After the move, got the children to join in activities in the place. * Help the children keep in touch with friends from the neighborhood before through telephone, letters, e-mail, and personal visits.
Ans: Question: The passage mainly wants to _Options:A tell parents the reasons of moving.B explain the reasons of stress.C give parents some advice on moving.D teach parents how to move.Answer:C
