Dollars and cents are the basic units of American money. The back of all dollar bills are green (hence "greenbacks"). The commonly used coins are: one cent (penny), five cents (nickel), 10 cents (dime), and 25 cents (quarter). 50 pieces (half dollar) and silver dollars (not really silver anymore) are gaining in usage, while there has been talk of phasing out the penny that’s inflation for you. "Always carry plenty of quarters when travelling. Very useful for phones, soda machines, laundry machines, etc."
There is generally no problem in using US dollars in Canada, but this is never possible in reverse. It’s useful always to carry small change for things like exact fare buses, but do not carry large sums of cash. Instead keep the bulk of your money in travellers’ cheques which can be purchased both in the US and abroad and should be in dollar denominations. The best known cheques are those of American Express, so you will have the least difficulty cashing these, even in out of the way places. Thomas Cook travellers’ cheques are also acceptable, especially as lost ones can be reclaimed at some car rental companies. Dollar denomination cheques can be used like regular money. There’s no need to cash them at a bank: use them instead to pay for meals, supermarket purchases or whatever. Ten or twenty dollar cheques are accepted like this almost always and you’ll be given change just as though you’d presented the cashier with dollar bills. Be prepared to show ID when you cash your cheques.
Credit cards can be even more valuable than travellers’ cheques, as they are often used to guaraniee room reservations over the phone and are accepted in lieu of deposit when renting a car—indeed without a credit card you may be considered so untrustworthy that not only a deposit but your passport will be held as security too. The major credit cards are VISA, Master Charge and Access, Diners Club and American Express. If you hold a bank card, it could well be worthwhile to increase your credit limit for travel purposes—you should ask your bank manager.

Why is it useful to carry enough 25-cent coins with you（）

A:They can act as small change for the exact bus fares. B:There is generally no problem in using them in Canada. C:As a basic unit of money, they are gradually gaining in usage. D:They may come in handy for pay phones or laundry machines.

Passage Three Harry Potter fans will instantly recognize the snowy owl as Harry’s famous companies, Hedwig, but these beautiful owls are easily recognizable not for their magical associations, but for their large size and striking while feathers. Snowy owls are, in fact, the only white owl, and they are a highly sought after species for many birdwatchers to add to their life lists. Foods: Small mammals, birds, fish. Habitat and Migration: Snowy owls are found in far northern latitudes including tundra, a vast treeless frozen region in the Arctic. Their breeding grounds (繁殖地） are in the Arctic tundra, and they migrate south throughout Canada during the winter. In exceptionally server winters or when food supplies are searce, these owls can appear much further south than their normal range. While principally a North American bird, they can also migrate to the northern areas of Europe an Asia. Behaviour: Snowy owls, like all owls, are powerful animal bunters that are active mostly at night but can bunt and feed during the day, especially when food supplies are low. These owls will rest on the ground or on rocks, stumps and other low favorable points. Males can be fierce when defending the nest, and both genders will also perform an “injured bird” act to tempt animal invaders to go away from the nest. Reproduction: Snowy owls may incubate (孵卵) 3-10 eggs for 30-34 days, or the incubation may be done primarily by the freak. The baby owls remain in the nest for 14-21 days and will attempt their first flight when they are 42-58 days old. Mated pairs will raise one group of young birds per year unless food supplies are inadequate and then no eggs may be produced. What does Paragraph 3 tell about snowy owls

A:The can be found in Asia and Europe B:They live in groups in hard winter days C:Their breeding grounds are in areas south to Canada D:They appear in the Artic when food supplies are scarce

TapeStore is a new kind of tape storage system which can store up to 6,000 computer tapes. No other tape storage system can hold as many computer tapes as TapeStore. The tapes look exactly like video cassettes. Many hundreds of data files can be stored on each tape, up to a maximum of 500 million bytes (字节) of data. If you stored the same amount of information on paper, you would need nearly 4.5 billion printed pages.
The machine is a tall black box with a mechanical arm. The machine is 2.5 metres high and 3.0 metres wide. This is how it works. Each tape has a code printed on it. You feed the code number into TapeStore, which then looks for the code. As soon as TapeStore locates the code, the arm reaches in and pulls out the tape.
The system is very fast. It takes the mechanical arm about 10 seconds to find the tape it is looking for. The machine then searches the tape to extract (提取) the required file, and this takes less than a minute. A．human technician would have to locate and remove the tape by hand, and could take at least an hour to find the right file on the tape.
Some of the world’s biggest companies, including banks, insurance companies, airlines, telephone companies, utilities and computer centres, have bought the system. They like it particularly because the system guarantees the security of their data.
TapeStore was originally developed in Canada and is now being marketed worldwide. In Europe alone, 750 have already been installed at a cost of 480,000 dollars each.
TapeStore is better than any other storage system because

A:it can store more video cassettes. B:it is extremely small. C:it stores more tapes. D:it stores data files on the same tape.

Hundreds of thousands of people supporting immigration fights in the U.S. filled streets all over America in early 2006. Many held signs and American flags and asked to be treated as citizens not criminals. Many of these supported legislation from Senator John McCain that would open a path to citizenship to immigrants who were already in the country illegally. Proposed legislation from other politicians called for stricter measures, including rounding up undocumented immigrants and sending them back to their home countries.
Canadian officials say that immigration applications continue to rise. Some want to keep the doors open. They need the labor. About 400,000 immigrants were allowed into the country in 2005, according to the Canadian Government statistics. However, all this growth means that cities need to adapt. Newcomers don’t always make a smooth transition into jobs for which they are skilled. So industries are using mentoring programs to help new immigrants find proper jobs.
With the large numbers of undocumented African immigrants arriving in the Canary Islands and showing no sign of abating, the Spanish Government has decided to get tough. There will be no more mass amnesties for illegals, and anyone coming to Spain without permission will be sent back, the government has announced. About 23,000 migrants landed on the islands in 2006, and riots have erupted in some crowded reception centers. This has promoted local authorities to appeal to the United Nations for help.
France’s new immigration and integration law gives the government new powers to encourage high-skilled migration. It takes effect in 2007. The new law authorizes the government to identify particular professions where France has a talent shortage. Then the government will help these identified employers find immigrant workers with needed skills or qualifications. The selected foreign employees will be granted "skills and talents" visas, valid for three years. But some concern that it’ll cause brain drain in developing countries.
Some Canadian officials want to keep the door open because ______.

A:Canada is in desperate need of talented people B:Canada can feed a much larger population C:Canada is suffering from labor shortage D:Canada is a multicultural country
