In the face of rising gas costs, many consumers are beginning to consider the choice of a hybrid(混合动力的) vehicle--one which operates on both gas and electricity. All of the models of hybrid car will save money, but are they really effective when all of the costs of maintenance(维修) and other considerations are included in?
First of all, consider the cost of buying a hybrid vehicle. Depending on the model, hybrid vehicles can cost anywhere from $2,000 to $5,000 more than the traditional models. However, some say that as the hybrid cars become increasingly more available as a reflection of demand, the prices can be expected to drop, making them more cost effective when it comes to the initial investment(初始投资).
Also important to keep in mind is the fact that the hybrid cars have a much more specialized system than the standard vehicle, and will therefore require more specialized workers to repair them when they break down.
It seems as though, at least for the time being, the purchase of a hybrid vehicle for the average consumer may not be the best choice when it comes to saving money. It is important to keep several things in mind, however, when considering purchasing a hybrid model. Many consumers are choosing to purchase these cars because they represent a significant development in terms of environmental concerns over standard models. They also mean that as a whole, Western nations will become less dependent on oil as the only means of power.
Finally, it is necessary to remember that the hybrid car is a very new technology. Developed only within the last few years, the technology is still in the starting stage, where costs will continue to be high. As time passes, the development of the hybrid technology will begin to push prices down to the point where hybrids are more competitive with the traditionally fueled models of the past.

Most students try to learn English grammar using grammar textbooks. They study grammar rules and take grammar tests. They use an analytical（分析的） approach, attempting to memorize, and then apply, a great number of rules.
However, research has proved this method inefficient and ineffective. The truth is, the human brain simply cannot consciously remember process and use hundreds of or thousands of grammar rules. Real speech is too fast.
Native speakers do not learn grammar in this way, but rather intuitively (凭直觉地) and unconsciously. They learn in a complete way, not by attempting to memorize individual grammar rules. As a result, native speakers use correct grammar fluently and easily.
Fortunately, it is possible for English learners to learn grammar this way. Language teacher Blaine Ray has developed a unique "intuitive" approach to teach English grammar. Her system uses "point of view" stories to teach the patterns of English grammar, allowing students unconsciously to acquire correct grammar without ever studying grammar rules.
In this system, the teacher first tells a simple story from one point of view. It may be told about the past, then repeated, but beginning with "since he was a child"; then repeated again, but this time about the future.
Listening to these stories allows students intuitively and effortlessly to learn English grammar and makes them be able to use it correctly when they speak.
Point of View Stories is a creative new way to study English grammar, and offers hope to millions of frustrated English learners.Which of the following ways is approved by the author?
| A．Remembering grammar rules. |
| B．Taking grammar tests. |
| C．Analyzing grammatical structure. |
| D．Applying language to situations. |
What does the underlined part "this way" in the fourth paragraph refer to?

Most children, even the youngest of children, are delighted to be around cats and dogs. But these pets carry plenty of germs and allergens（过敏原）, prompting researchers to ask: Are cats and dogs really safe for children？
A study finds that, contrary to many parents’ fears, owning cats or dogs does not increase a child’s risk of developing allergies, and in fact, may actually protect them. The study’s lead author, Dr. Dennic Ownby of the Medical College of Georgia, says that even he was “very surprised” by the results. Ownby and colleagues followed more than 470 children from birth to age 6 or 7, comparing those exposed to cats and dogs during their first year of life to those who were not.
By using skin-prick(刺) tests for detecting common allergies, the researchers found that, contrary to what many doctors had been taught for years, children who had lived with a pet were not at greater risk.
Even more remarkable, children who had two or more dogs or cats had an even greater reduction, up to 77 percent, in risk of allergies. Researchers suggest this protective effect may be the result of early exposure to lots of bacteria that are carried by dogs and cats. Exposing young children to these bacteria helps" exercise" their immune systems early in life so that they're better able to resist allergic diseases later.
There's something very important in that first year of life when the immune system is developing that we can retrain it away from an allergic response, said Dr. William Davis.
And while researchers are not encouraging parents to buy dogs or cats just to reduce a child’s allergy risk, they say if a family already has one or more animals, there's no need to get rid of them. Why do the researchers feel “very surprised” by the results of the study?
| A．Because the results are contrary to their expectation． |
| B．Because so many children are playing with cats and dogs． |
| C．Because parents are so much worried about their children． |
| D．Because children with animals may develop allergies easily． |
Compared with children who have pets，those who haven’t ______.
| A．will lose the chance to develop immune system |
| B．may suffer allergic diseases more often |
| C．will reduce the harm from bacteria |
| D．can keep doctors away |

| A．pets are ill-treated by their owners |
| B．less families would like to own cats and dogs |
| C．keeping pets is a good way to keep children healthy |
| D．the results of the study can make families with pets feel at ease |
The underlined word “it” in the fifth paragraph refers to________.
| A．the early life | B．an allergic disease |

The koala is one of Australia’s most treasured creatures, which is a lovely little creature. But now, it is in big trouble.
Affected by habitat (栖居地) loss and climate change, like many other uniquely Australian animals, koalas are being squeezed into smaller regions. But at present, it is a deadly disease, a somewhat silent killer that causes a further decline in the koala population, that is worrying many scientists about the fate of the koala.
The killer is Chlamydia, which has caused symptoms in up to 50 percent of the wild koalas, with probably even more infected (感染) but not showing symptoms. It has been particularly severe in Queensland, where nearly all koalas are infected. The disease causes many symptoms including eye infections, which can lead to blindness, making it difficult for them to find their primary food.
Treating Chlamydia in wild koalas is a challenge. There is no treatment available for it. Only a small percentage of the animals can be treated successfully and returned to the wild. Besides, there is no national plan in Australia to save the koala；it is up to each region to make management plans for its koala population.
The good news is that researchers are working to test a vaccine (疫苗) that would help prevent further spread. If all goes well, plans can be carried out to distribute the vaccil1e more widely. But it’s impossible to vaccinate all wild koalas.
Another possibility would be to make vaccine distribution a routi11e part of treatment for the thousands of koalas brought into care centers every year after they are injured by cars or dogs.
While it is a combination of problems that are affecting the wild koala population, many experts believe this vaccine would be an important step in helping koalas survive longer. It may buy enough time to give researchers a chance to solve some of the other problems facing Australia’s koalas.Which isn’t considered the main cause of koala’s population decline?
| A．Habitat loss. | B．Injuries from cars and dogs. |
| C．Climate change. | D．A deadly disease. |
The third paragraph mainly tells us .
| A．the serious result Chlamydia has caused to the koala |
| B．Chlamydia affected the koala only in particular regions |
| C．the most serious symptom of Chlamydia is eye infections |
| D．Chla1nydia can seriously affect koala’s primary food |
The underlined word “it” in the fourth paragraph probably refers to .
| A．the koala | B．Chlamydia | C．national plan | D．eye infection |
We can learn from the text that the vaccine .
| A．would cure the killer Chlamydia quite effectively |
| B．would only be distributed in koala care centers |
| C．has already been put into practical use in Australia |
| D．cannot be distributed to all the infected koalas |
It can be inferred from the text that .
| A．a national plan for saving koalas will be made soon in Australia |
| B．koala population is declining only in a few regions |
| C．researchers need enough time to so1ve the koala problems |
| D．experts have lost the best chance to save the infected koalas |
If a city wishes to host the Olympics, it must submit a proposal(提交提案) to the IOC. After all proposals have been submitted, the IOC votes. If no city with the fewest votes is eliminated, the voting continues, until a majority winner is determined. Typically the Games are awarded several years in advance, allowing the winning city time to prepare for the Games.
In selecting the site of the Olympic Games, the IOC considers a number of factors, and chiefly among them is which organizing committee seems most likely to stage the Games effectively. The IOC also considers which parts of the world have not yet hosted the Games. For instance, Tokyo, the host of the 1964 Summer Games, and Beijing, that of the 2008 Games, were chosen in part to popularize the Olympic movement in Asia. Because of growing importance television worldwide, the IOC in recent years has also taken into account the host city’s time zone. Whenever the Games take place in the USA or Canada, for example, American television networks are willing to pay specially higher amounts for television rights because they can broadcast popular events live in the best viewing hours.
Once the Games have been awarded, it is the duty of the local organizing committee----not the IOC or the NOC of the host city’s country to provide them with money. This is often done with a part of the Olympic television revenues(收入), and corporate sponsorships(社团赞助), tickets sales, and other smaller revenue sources. In many cases there is also direct government support. Although many cities have achieved amounts of money by hosting the Games, the Olympics can be financially risky. When the financial gains from the Games were less than expected, the city was left with large debts._______will be determined to host the Olympic Games by the IOC.
A. A city that submits a proposal B. A majority winner in voting
C. A city that has perfect time zone D. One that hasn’t hosted the Games Which of the following words can be used to replace the word “ selecting” in paragraph 2?

If the Games take place in Canada, American television networks___.
| A．can’t broadcast popular events live in the best viewing hours |
| B．will be forbidden to broadcast live sporting events |
| C．are willing to pay much higher amounts for television rights |
| D．will not pay for the Canadian television networks |

| A．The host city must be left with large debts |
| B．The city may achieve a lot of money |
| C．There is no financial risk in hosting the Olympic Games |
| D．It is impossible that the host city couldn’t make money |
Which of the following can be the best title of this passage?
| A．How to host Olympic Games | B．Winner or loser |
| C．Applying for host for Olympics | D．The Olympic Games |
When asked why he or she wears clothes, some people will probably answer "to keep warm and to cover my body". These are the basic reasons why clothes are worn, but people also want to look attractive and appear successful to others.
If people only wore clothes for warmth and to cover their bodies, most clothes would be simple and cheap. In most Western countries, however, clothes are sometimes very expensive. The main reason for this is not the cost of the cloth or the cost of making the clothes. The clothes are expensive because of fashion.
Successful businessmen, for example, often wear very expensive suits, shirts and ties. Sometimes they pay thousands of dollars for a suit and hundreds of dollars for a tie. It’s just a suit and a tie but they pay these prices because of the famous name of the designer. A suit costing much less would be just as warm and would cover the wearer's body just as well.
Fashion is always changing, which means those who want to be fashionable have to buy new clothes every few months, even if last month's clothes have only been worn once or twice. Some people have wardrobes full of clothes that have hardly been worn but are no longer in fashion. Being fashionable, therefore, can be a very expensive pastime! What do people basically wear clothes for?
| A．Looking attractive to others. | B．Following the fashion. |
| C．Appearing successful to others. | D．Keeping warm and covering bodies. |
The main reason why clothes are sometimes very expensive is that _______.
| A．one has to buy new clothes | B．these clothes are in fashion |
| C．the cost of the cloth is high | D．making clothes costs much |
We can learn from the passage that _______.
| A．expensive clothes are not any warmer than cheap ones |
| B．fashion is not always changing |
| C．expensive clothes are warmer |
| D．fashion designers like expensive clothes |
What does the underlined word “wardrobes” in Paragraph 4 mean?
