Today’s drivers may feel shocked by the high price of petrol when they drive to the gas station. However, the car industry has the technology to solve the problem. It’s the hybrid car(混合动力汽车).

   What is a hybrid car? Any car that uses two or more sources of power is a hybrid car. Most hybrid cars on the road right now are petrol-electric hybrids. The petrol-electric hybrid car is just what it sounds like — a cross between a petrol-powered car and an electric car.

    A gas-powered car has a fuel tank(油箱), which supplies petrol to the engine. An electric car, on the other hand, has a set of batteries that provides electricity for the car.

    To be useful to you or me, a car should be able to run at least 300 miles (483 km) before refueling, be capable of(能够) being refueled quickly and easily and fast enough to keep up with the other traffic on the road.

    A petrol car meets these requirements(要求)but produces a large amount of pollution. An electric car, however, produces almost no pollution, but can only go 50 to 100 miles (80 to 161 km) between recharging(充电). And the problem has been that the electric car is very slow and inconvenient to recharge.

    A petrol-electric car combines the advantages of the two power sources into one system that uses both gas power and electric power. Some experts believe that the hybrid car is “the next generation of smart cars”. A hybrid car can go up to 50% further than a traditional car can on the same amount of gas! It saves driver’s money on gas and cuts air pollution!

What do the underlined words “the problem” in Paragraph 1 refer to?

A. The price of petrol goes up and down.     B. The gas-powered car is sold at a high price.

C. The gas-powered car causes air pollution.   D. The price of petrol keeps going up.

How many sources of power do most hybrid cars use?

A. Two.             B. Three.            C. Four.         D. It depends.

The author thinks that electric cars _____.

A. are smart vehicles     B. are popular vehicle  C. are not practical  D. are not slow

Some experts believe that the hybrid car will have a large market in future because _____.

A. it is just powered by renewable energy   B. it saves money and is eco-friendly

C. it goes further than a traditional car      D. it is safe, cheap and produces no air pollution

On March 23, 2010, Google Inc took a major step in withdrawing(收回) its search-engine services from Beijing to Hong Kong. Google acknowledged that it failed to make progress in talks with the Chinese government for permission to let Google stop censoring(审查) its search results.
Since posting the announcement on its website, Google’s stock(股票) price has fallen from $595 to about $567, while Baidu, the leading search engine in China, has seen its stock price rise by 50%. A potential foreign beneficiary(受益者) is Bing, Microsoft’s new search engine. And while Bing may not exactly have got the keys to a very rich kingdom, its managing group understand their good fortune and have not been shy about sticking the knife into Google. Craig Mundie, a chief officer of Bing, told China Daily that “we feel good enough now,” adding, “but it’s a 20-year journey, and not just three years. And Microsoft is here to stay.”
Several other Chinese Internet companies are no doubt moving swiftly to take advantage of this situation. Both Sohu. com—a Yahoo-like website in China— and a hugely successful instant-messaging company called Tencent(腾讯) are already trying to hire Google China staff. Analysts believe that of the two, Tencent is in the better position. Nearly 70% of China’s 400 million Internet users use instant-messaging, and of those, 80% use Tencent’s system, known as QQ. That’s the major reason why Tencent’s potential market is bigger than Baidu’s, and an insider at the company acknowledges that the search business is full of opportunities.
All the competitors of Google do what the Chinese government requires: censor their search results. If Microsoft and the others intend to be in China “to stay,” as Craig Mundie put it, there is no chance that the censoring principle will change for them.
As to the Google’s exit, one of its investors made the comment recently, “There’re still a lot of us who believe that they’ve made the wise choice. But Google is apparently out and I guess we just get to accept.” However, some Chinese netizens regretted the loss of its professional services on google. cn, such as maps, videos, music and translations.
73.Google.cn stops its business in China because _____.
A. too many companies enter the market         B. its stock price has fallen sharply
C. Chinese companies hire its workers           D. it refuses to censor the search results
74.How many Chinese beneficiaries are mentioned in the passage?
A. Two.               B. Three             C. Four.               D. Five.
75.When Google withdraws, _______.
A. Chinese netizens won’t have any professional service
B. only Chinese companies will provide search service
C. China’s attitude towards censoring won’t be changed
D. the Google managing group will regret its decision
76.A suggested title for this news would be ______.
A. When Google Withdraws From China        B. Who Wins in China’s Search Business
C. Who Will Profit When Google Exits         D. Why Google Loses to Other Competitors

LONDON—Archaeologists have discovered a smaller prehistoric(史前) site near Britain’s famous circle of standing stones at Stonehenge.

Researchers have named the site “Bluehenge” after the color of the 27 Welsh stones that were laid to make up a path. The stones have disappeared, but the path of holes remains.

The new circle, unearthed over the summer by researchers from Sheffield University, represents an important find, researchers said Saturday. The site is about a mile away from Stonehenge.

Bluehenge, about 80 miles southwest of London, is believed to date back to about the time Stonehenge was built, about 5,000 years ago.

Mike Parker Pearson of Sheffield University said he believed the path and stonehenge itself were linked to rituals(仪式) of life and death.

Mike Parker suggested that the ancient funerary rituals began at a different circle site known as “Wood-henge”, which represented the world of the living. The bodies of the dead were then brought down the River Avon to Bluehenge, which represented death, and were finally carried along a ceremonial route known as the Avenue to Stonehenge.

Bournemouth University Professor Tim Darvill, an expert on Stonehenge, told Britain’s Dail Mail that Bluehenge “adds to the richness” of the ancient site’s story.

“This henge is very important because it forms part of the picture of ceremonial monuments in the area and puts Stonehenge into context,” Darvill was quoted(引述) as saying. “It’s no longer Stonehenge standing alone, but it has to be seen in context with the landscape.”

1.How many henges are mentioned in this passage?

A.Two             B.Three        C.Four          D.Five

2.Who believed the Stonehenge is related to ancient ritual of death?

A.Stonehenge has noting to do with Bluehenge

B.Woodhenge represented the world of living in ancient times.

C.Bluehenge represented death

D.Stonehenge, Woodhenge and Bluehenge should be studied together

4.From the passage we can learn that ______.

A.researchers have named the site “Bluehenge,” because they have found blue huge stones there
