阅读文章，回答下列各题： Some people seem to have a knack(诀窍) for learning languages.They can pick up new vocabulary, mas-ter rules of grammar, and learn to writein the new language much more quickly than other people. They do not seem to beany cleverer than others. What makes language learning so much easier for them？Perhaps if we take a close look at these successful language learners, we maydiscover a few techniques which make language learn-ing easier for them. Firstly, successful language learners areindependent learners. They do not depend on the book or the teach-er; they drather discover their own way to learn the language than wait for the teacherto explain everything.They try to find the sentence patterns, the rules and themeaning of the new word by themselves. They are good guessers. They look forclues and form. their own conclusions. When they guess wrong, they guess again.They try to learn from their mistakes. Besides,successful language learning is active learning. Therefore, successful learnersdo not wait for achance to use the language; they look for such a chance. Theyfind people who speak the language and they ask these people to correct themwhenever they make a mistake. They will try anything to communicate. They are notafraid to repeat; they are willing to make mistakes and try again. Whencommunication is difficult, they can accept information that is inexact orincomplete. It is more important for them to learn to think in the language thanto know every word s meaning. Finally,successful language learners are learners with a purpose. They want to learnthe language because they have an interest in the language and the people whospeak it. It is necessary for them to learn the language in order to communicatewith these people and to learn from them. Successful language learners are independent, so successful learners __________ A．depend on the book or theteacher B．wait for the teacher toexplain everything C．learn from their mistakes D．discover their own way tolearn languages

our eating habits are very important in our daily life. There are times when most of us would rather eat sweets and ice cream than meat and rice. Actually, sweets and ice cream are not bad for the stomach if we eat them at the end of a meal. If we eat them before a meal, they may take away our appetite. Meanwhile, it is important for us to eat our meal at the same time each day. When we feel hungry, it shows that our bodies need food. When we feel angry or excited, we may not want to eat. When we are worded, we may not want to, eat, either. A long time ago, in England, some judges used to decide whether, a man was telling the truth by giving him some dry bread. If the man could not swallow the bread, it was a sign that he wasn' t telling the troth. Although this seems very strange and rather foolish, it is indeed an excellent way of finding out the truth. A man who is worrying about something has difficulty in swallowing anything dry. He loses his appetite and does not want to eat anything if he is worrying something. We have to develop good ,eating habits because__________

A. we want to be healthy and strong

B. we want to enjoy our food

C. we want to eat more

D. we want to save time

form. of anunfavorable trade bal- ance (贸易逆差)with-other nations. Such an imbalance exists when the total valueof a country's imports ex- ceeds that of its exports. For example, if a countrybuys $ 250 billion of products from other countries, yet sells only $ 100billion of its own products overseas, its trade deficit is $ 150 billion. Manyunderdeveloped nations find themselves in this position because they lacknatural resources or the industrial capacity to use these resources, and thushave to import raw materials or manufactured goods. One effect of a trade deficit is the flowof currency (货币)out of a country. In the case of an underdeveloped nation, this cancause many financial difficulties, including failure to meet debt payments andobstacles to creation of an industrial base. Even in the case of a fullydeveloped nation such as the United States, a large tradedeficit is reason for alarm. American products, made by well-paid workers in USindustries, cost more to produce than those made in places like Asia, wherelabor and material costs are much lower. Money spent on foreign products ismoney not spent on items produced by domestic industries. Whatis the passage mainly about？

A. Several worldwide economic problems.

B. The causes and consequences of tradedeficit.

C. Lack of resources in underdevelopedcountries.

D. The value of exports against imports.

ue to stamp collectors. A mistake on one inexpensive postage stamp has made the stamp worth a million and a half times its original value. More than one hundred years ago in the British colony of Mauritius, a small island in the Indian Ocean, the mistake was made. In 1847 an order for stamps .was sent to a London printer -- Mauritius was to become the fourth country in the world to issue stamps. Before the order was filled and delivered, a bail was planned at Mauritius' s Government House, and stamps were needed to send out the invitations. A locai printer was instructed to copy the design for the stamps. He accidentally inscribed the words "Post Office" instead of "Post Paid" on the severai hundred stamps that he printed. Today there are only twenty-six of these misprinted stamps left-fourteen One Penny Orange - Reds and twelve Two Penny Blues. Because of the Two Penny Blues' rareness and age, collectors have paid as much as $16,800 for it. Over a century ago, Mauritius__________

B. was a smail island in the Pacific Ocean

C. belonged to India

D. was one of the British colonies
