题目列表(包括答案和解析)


C
Still want a laptop? That was so yesterday. Get ready for the next stage in the personal computer revolution: It's the ultrathin (超薄的), cheap netbook.
According to a New York Times report last week, personal computers are about to go through their biggest change since the rise of the laptop. By the end of the year, consumers are likely to see laptops the size of thin paperback books that can run all day on a single charge and are equipped with touch screens or slide-out keyboards. The netbook is a kind of portable computer with learner functions for online surfing and basic computing activities, for example, word processing. To cut the cost and weight, they usually have a low-powered processor, small screen, narrow keyboard, and no ODD.
Currently, some of the devices look more like a toy than a full-feature computer. That's because most of the netbooks sold today run on an Intel chip called Atom. This is a lower-power version of the company's standard laptop chip, so they have trouble running demanding software like games and photo-editing programs.
This year, a group of companies who make cheap, power-saving chips used in cell phones are applying that expert skill to PCs. That means they will break Atom's netbook dominance (统治地位) and reduce the size while letting it run complicated programs.
The big winner in the rise of netbooks will be the consumer. AT&T announced last week that customers in Atlanta, Georgia, US, could get a netbook for just $50 (342 yuan) if they signed up for an Internet service plan. This trend will soon spread to Asia, according to industry experts.
University campuses are a major target of Shanzhai netbooks—uncopyrighted (无版权的) domestic copies of foreign brands. These products are usually sold at less than 2,000 yuan. But industry insiders suggest students not use these nameless products because many of them don't provide good after-safes services.
49.The following are all advantages of netbooks EXCEPT that      .
A.people can easily edit photographs with them
B.they cost less than other personal computers
C.they are very thin and easy to carry
D.they save power
50.Why are students advised not to use Shanzhai netbooks?
A.Because they are of poor quality.
B.Because they are not easy to operate.
C.Because they will soon be out of date.
D.Because they lack good after-sales services.
51.What can be inferred from the passage?
A.Laptops are becoming more and more popular.
B.University students seldom buy Shanzhai netbooks.
C.Shanzhai netbooks are sold better than those of famous foreign brands.
D.Atom's netbooks make up the largest part of the sales of portable computers at present.
52.What is the general idea of this passage?
A.Shanzhai netbooks are taking control of laptop market.
B.Netbooks have advantages over laptops in everything.
C.Netbooks are becoming the trend of personal computers.
D.Most of the netbooks sold today run on an Intel chip called Atom.

Shopping green can make an important contribution to protecting the planet and conserving its resources.

Today’s consumer faces a wider range of choices than ever before, Add to that the steady stream of sales campaigns, and shopping smart only gets harder. To buy economically and reduce waste, safeguard health and protect the environment, you’ll need to follow some basic principles and have a clear idea of what you want.

1. Do Your Homework

Before making any major purchase, take the time to research it. Plentiful resources are usually available online. Avoid buying in a hurry, and don’t be persuaded by overenthusiastic salespeople. Sleep on it if necessary—you won’t regret giving yourself some extra time to think.

2. Take the Long View

Consider the running costs as well as the initial price of any item you buy. Many environmentally friendly products cost more to buy, but save you money in the long run. Choose items that are made to last. For example, pick a sofa that has a hardwood or steel frame rather than one made of softwood, which may break easily.

3. Skip the Disposable Option

Buy reusable products like washable cloth towels, handkerchiefs, serviettes(餐巾)and cleaning cloths rather than paper, single-use varieties. Avoid other disposable supplies like cups, glasses, and chopsticks, too.

4. Take the Local Route

Buy local products that are in season. It’s usually cheaper and fresher and has less harm to the environment. Markets and roadside stands are good sources. Some supermarkets also buy from local producers. Support it if you have one.

5. Avoid Wasteful Packaging

Better not buy products that have too much packaging. It’s estimated that approximately 10 percent of every shopping bill is actually paying for packaging—which you normally just throw away! Moreover, significant amounts of energy are used in the production of packaging. Purchasing refillable and renewable containers can also help cut this kind of waste.

1.What could be the best title for this passage?

A. Protection of the Planet

B. Green Shopping Principles

C. Environmentally Friendly Products

D. Resource Conservation

2.The underlined phrase “sleep on it” has the similar meaning with       .

A. think it over                                     B. forget about it

C. set it aside                                              D. put it into action

3.Why does the author advise us to buy lasting products?

A. Because they are less expensive to buy.

B. Because they save money in the long run.

C. Because they will never break.

D. Because they are local products.

4.Which of the following can be considered green shopping?

A. Following the stream of sales campaigns.      

B. Buying disposable chopsticks.

C. Focusing on packaging.

D. Purchasing from local markets.

Americans are proud of their variety and individuality, yet they love and respect few things more than a uniform, whether it is the uniform of an elevator operator or the uniform of a five-star general.Why are uniforms so popular in the United States?

Among the arguments for uniforms, one of the first is that in the eyes of most people they look more professional than civilian(百姓的)clothes.People have become conditioned to expect superior quality from a man who wears a uniform.The television repairman who wears uniform tends to inspire more trust than one who appears in civilian clothes.Faith in the skill of a garage mechanic is increased by a uniform.What easier way is there for a nurse, a policeman, a barber, or a waiter to lose professional identity(身份)than to step out of uniform?

  Uniforms also have many practical benefits.They save on other clothes.They save on laundry bills.They are tax-deductible(可减税的).They are often more comfortable and more durable than civilian clothes.

  Primary among the arguments against uniforms is their lack of variety and the consequent loss of individuality experienced by people who must wear them.Though there are many types of uniforms, the wearer of any particular type is generally stuck with it, without change, until retirement.When people look alike, they tend to think, speak, and act similarly, on the job at least.

  Uniforms also give rise to some practical problems.Though they are long-lasting, often their initial expense is greater than the cost of civilian clothes.Some uniforms are also expensive to maintain, requiring professional dry cleaning rather than the home laundering possible with many types of civilian clothes.

It is surprising that Americans who worship variety and individuality _______.

     A.still judge a man by his clothes

     B.hold the uniform in such high regard

     C.enjoy having a professional identity

     D.will respect an elevator operator as much as a general in uniform

People are accustomed to think that a man in uniform _______.

     A.suggests quality work

     B.discards his social identity

     C.appears to be more practical

     D.looks superior to a person in civilian clothes

The chief function of a uniform is to _______.

     A.provide practical benefits to the wearer

     B.make the wearer catch the public eye

       C.inspire the wearer’s confidence in himself

     D.provide the wearer with a professional identity

The best title for this passage would be _______.

     A.Uniforms and Society

     B.The Importance of Wearing a Uniform

     C.Practical Benefits of Wearing a Uniform

     D.Advantages and Disadvantages of Uniforms
