題目列表(包括答案和解析)

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 (主食加工)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(多樣化)food. But that is possible not the most important one. The most important one is that there is a tremendous migration(移民)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.

1.What does the word "hikes" in Paragraph 3 probably refer to?

A. big changes B. large increases C. long trips D. big bills

2.Wheat price exploding indicates_____.

A.sub-Saharan countries need to increase wheat production badly

B.sub-Saharan countries have to issue more money

C.sub-Saharan countries should grow more Corn

D.importing much wheat is urgent

3.Why is there a higher demand for wheat in sub-Saharan Africa?

A.Because the number of hungry people there is increasing.

B.Because higher income people have the diversified need of food.

C.Because male labor are crowding into the cities.

D.Because the wheat price is lower.

4.According to Mr. Braun the main challenges for growing more wheat in Africa are_____.

A.climate change and disease

B.resistant crops and climate change

C.rising temperatures and disease and pests

D.disease and pests and inconvenient transportation

閱讀下列短文,從每題所給的四個選項(A、B、C和D)中,選出最佳選項。

  Although there is no formal process of selection, in larger groups, leaders are usually chosen formally through election or recruitment(招募).

  Although leaders are often thought to be people with unusual personal ability, decades(十年)of research have failed to produce evidence that there are any “natural leaders”.It seems that there is no set of personal qualities that all leaders have in common; or rather, any person may be recognized as a leader if the person has qualities that meet the needs of that particular group.

  Research suggests that there are typically two different leadership roles that are held by different individuals.Instrumental leadership is leadership that emphasizes the completion of tasks by a social group.Group members look to instrumental leaders to “get things done”.Expressive leadership, on the other hand, is leadership that emphasizes the collective well-beings(福利)of a social group's members.Expressive leaders are less concerned with the overall goals of the group than with providing emotional support to group members and attempting to minimize tension and conflict among them.

  Instrumental leaders are likely to have a rather secondary relationship to other group members.They give others and may discipline group members who inhibit(阻礙)attainment of the group's goals.Expressive leaders develop a more personal or primary relationship to others in the group.They offer sympathy when someone experiences difficulties and try to solve problems that threaten to divide the group.As the difference between these two roles suggests, expressive leaders generally receive more personal affection from group members; instrumental leaders, if they are successful in promoting group goals, may enjoy a more distant respect.

C.

Dear sir,

I am Li Hua, a senior high school student in China. I am very interested in digital products. I heard your company’s digital products are of excellent quality. Recently your company released a newly-produced digital album, but I can’t find much information about this new product from your company’s website. If it is convenient for you, could you send me some information about it, such as product manuals and guides? I’m thinking about buying this album as a present for my mother’s birthday.

I am looking forward to your reply.

Yours faithfully,

Li Hua
