One Canada, Two Languages

Canada is one of the few nations in the world to have two official languages: English and French. There are 10 provinces in the country but only one of these—Quebec is known as ―French Canada‖. This is because it was founded by French explorers while British adventurers discovered the rest.

Canada left the British empire(帝国) in 1867 to become an independent country and English and French have been recognized as the official languages ever since.

Most people speak English as their first language and the two national television networks broadcast in English throughout the country. Apart from in Quebec and a few places on the east coast, French television is very rare.

The same goes for traffic signs and menus, for example, outside of Quebec, there are only a few places where you’ll see traffic signs in French. In restaurants, it’s almost impossible to find French on the menu unless you are in the heartland (中心地带) of French Canada. However, all products sold in Canada must, by law, have labels (标签) and instructions in both languages.

In Canada’s English- speaking provinces, official bilingualism (双语) means that students can choose to complete a special French language course. Under this program, they are taught most of their subjects in French.

If a student begins the course in kindergarten (幼儿园) or Grade One, it is likely that all their lessons will be in French. However, if they start at junior high school, 25 percent of the teaching

will continue to be in English.

21. How many provinces are there in Canada?

A. Ten.

B. Nine.

C. Eleven.

D. Two.

22. Which country controlled Canada before its independence?

A. France.

B. Britain.

C. America.

D. Germany

23. Where can you watch French television programs?

A. Only in Quebec.

B. In Quebec and a few other places.

C. From the two national television networks.

D. All over Canada

24. What do we know about the education in Canada?

A. In English- speaking provinces only English courses are offered.

B. If you choose a special French language course, most of the subjects are taught in French.

C. The courses in primary school are all taught in English.

D. Most of the courses in junior high schools are taught in English.

Can you remember the first time you learned how to ride a bike or drive a car? Learning these skills changed your life forever and opened up new horizons. Learning about computers can be like learning how to ride a bike or drive a car. Once you have invested the time to master the skills, you will never go back to the old days. The new technology is simply too convenient and too powerful.

Technological developments through the years have enabled us to do more with less effort. We have continuously looked for better ways of doing things. Each invention and new development has allowed us to extend our capabilities(能力). Today we see one of the most dramatic technologies ever developed—the computer. It extends the capabilities of our minds.

Computers have saved organizations millions of dollars. Furthermore, these same computer systems have opened up new opportunities that would have gone undiscovered or neglected. The computer can multiply what we can do, and the return on investment(投资)is high. The growth of computer usage is surprising. On the other hand, the computer can do serious damage. Invasion of privacy, fraud(欺诈),and computer-related mistakes are just a few shocking examples.

The computer is like a double-edged sword. It has the ability to cut us free from some activities, but it can also cut deeply into profits, personal privacy, and our society in general. How it is used is not a function of the current technology. It is strictly a function of how people decide to use or misuse this new technology. The choice is yours, and only through a knowledge of computer systems will you be able to avoid the danger while enjoying the many, many benefits of the computer age.

25. The writer thinks learning about computers is like learning how to ride a bike or drive a car

because_________.

A. it is simple and practical

B. it needs a lot of practice

C. it leads people to new life experience

D. it takes much time to master the skills

26. According to the passage, computers bring people the following benefits EXCEPT_______.

A. avoiding mistakes

B. saving money

C. making money

D. opening up opportunities.

27. According to the writer, the bad effects of computers can be avoided if we_______.

A. have a sound knowledge of computer systems

B. tell people not to misuse computers

C. have strict rules over the use computers

D. make more investments in the technology

28. This passage is probably written for______

A. computer teachers

B. computer producers

C. computer learners

D. computer programmers

C

Who's in control of your life? Who's pulling your strings? For the majority of us, it's other people-society, colleagues, friends, family or our religious community. We learned this way of operating when we were very young, of course. We were brainwashed. We discovered that feeling important and feeling accepted was a nice experience and so we learned to do everything we could to make other people like us. As Oscar Wilde puts it, "Most people are other people. Their thoughts are someone else's opinions, their lives a mimicry(模仿), their passions a quotation."

So when people tell us how wonderful we are, it makes us feel good. We long for this, good feeling like a drug—we are addicted to it and seek it out wherever we can. Therefore, we are so eager for the approval (赞同) of others that we live unhappy and limited lives, failing to do the things we really want to. Just as drug addicts and alcoholics live worsened lives to keep getting their fix（一剂毒品）, we worsen our own existence to get our own constant fix of approval.

But, just as with any drug, there is a price to pay. The price of the approval drug is freedom—the freedom to be ourselves. The truth is that we cannot control what other people think. People have their own agenda, and they come with their own baggage and, in the end, they're more interested in themselves than in you. Furthermore, if we try to live by the opinions of others, we will build our life on sinking sand. Everyone has a different way of thinking, and people change their opinions all the time. The person who tries to please everyone will only end up getting exhausted (tired) and probably pleasing no one in the process.

If the elder son could be a successful businessman, surely the younger one, with a higher education, would do much better. A few years later, the results of his decision became clear. Uninterested in business, the younger son continued spending his time enjoying himself. And he went out of business. But the elder son’s far smaller share (份) of business had expanded and he had proved himself to be a good decision maker. Ashamed at the turn of events, the father met the elder son and was angry with the younger one. The elder son, who was listening to all this quietly, suddenly said he wanted to set up an independent business and live on his own. “Why?” asked the father. “I blame (责备) one person for the way my brother has turned out, and it’s not him. You can’t blame children for the faults (过失) of their parents, can you?” asked the elder son. 1.Before the younger son went into the father 9s business, he .

With the car full of flowers we were going home. On our way back my wife noticed a cupboard (柜厨) outside a furniture shop. It was tall and narrow. “Buy it, ” my wife said at once. “We’ll carry it home on the roof rack. I’ve always wanted one like that.” What could I do? Ten minutes later I was ￡20 poorer; and the cupboard was tied on the roof rack. It was six feet long and eighteen inches square, quite heavy too. In the gathering darkness I drove slowly. Other drivers seemed unusually polite that evening. The police even stopped traffic to let us through. Carrying furniture was a good idea. After a time my wife said, “There’s a long line of cars behind. Why don’t they overtake, I wonder?” In fact a police car did overtake. The two officers inside looked at us seriously as they passed. But then, with great kindness, they led us through the rush-hour traffic. The police car stopped at our village church. One of the officers came to me. “Right, sir, ” he said. “Do you need any more help?” I was a bit puzzled. “Thanks, officer,” I said. “You have been very kind. I live just on the road.” He was staring at our car, first at the flowers, then at the cupboard. “Well, well, ” he said, laughing. “It’s a cupboard you’ve got there! We thought it was something else.”
