A recent study of ancient and modern elephants has come up with the unexpected conclusion that the African elephant is divided into two distinct (不同的) species
The discovery was made by researchers at York and Harvard universities when they were examining the genetic relationship between the ancient woolly mammoth and mastodon to modern elephants—the Asian elephant, African forest elephant and African savanna elephant
Once they obtained DNA sequences (序列) from two fossils (化石)，mammoths and mastodons the team compared them with DNA from modern elephants. They found to their amazement that modern forest and savanna elephants are as distinct from each other as Asian elephants and mammoths.
The scientists used detailed genetic analysis to prove that the African savanna elephants and the African forest elephants have been distinct species for several million years. The divergence of the two species took place around the time of the divergence of Asian elephants and woolly mammoths. This result amazed all the scientists.
There has long been debate in the scientific community that the two might be separate species but this is the most convincing scientific evidence so far that they are indeed different species.
Previously, many naturalists believed that African savanna elephants and African forest elephants were two populations of the same species despite the elephants’ significant size differences. The savanna elephant has an average shoulder height of 3.5metres while the forest elephant has an average shoulder height of 2.5metres. The savanna elephant weighs between six and seven tons, roughly double the weight of the forest elephant. But the fact that they look so different does not necessarily mean they are different species. However, the proof lay in the analysis of the DNA.
Alfred Roca, assistant professor in the department of Animal Sciences at the University of Minois, said, “We now have to treat the forest and savanna elephants as two different units for conservation purpose. Since 1950 all African elephants have been conserved as one species. Now that we know the forest and savanna elephants are two very distinct animals, the forest elephant should become a bigger priority (优先)for conservation purpose .” One of the fossils studied by the researchers is that of ________.
| A．the Asian elephant |

New York State has passed the USA’s first state law banning motorists talking on hand-held cell phones. The ban will begin November 1, although drivers caught using hand-held cell phones will be given only warnings during the first month.
First-time violators(违法者) will face a ＄100 fine. A second time call for a ＄200 fine and every violation after that will cost＄500．
At least a dozen localities(地方) have established bans, starting in 1999; and 40 states have had bans proposed but not passed．At least 23 countries, including the Great Britain, Italy, Israel and Japan, ban drivers from using hand-held cell phones.
There are about 115 million cell phones in use in the United States and more than 6 million in New York State.
“To think that I’m not going to use cell phone when at the same time I can still use my laptop, I still can read a paper, I can still change my pants(裤子) while driving 65 mph. I think there’s just something wrong,” an official said．
Other critics noted that other things like eating, drinking coffee and applying make-up while driving posed(造成) at least as much of a concern. They suggested that the ban include a broader range of things. How much fine will a hand-held cell phone user receive if he has been caught using it four times while driving after November?
| A．$500． | B．$1000． | C．$1200． | D．$1300． |
The official mentioned in this passage _______.
| A．does not agree with this ban |
| B．doesn’t believe using hand-held cell phones while driving will cause any danger |
| C．doesn’t understand why hand-held cell phones alone should be banned among many others |
| D．believes changing pants while driving will cause greater danger |
The writer intends to tell us in the last paragraph that _______.
| A．it is not fair to have this ban passed |
| B．the ban will never be passed in the whole country |
| C．more activities of the same kind should also be banned |
| D．the ban will meet with more criticism |

Everybody has had at least one experience from which he knows the meaning of life. This time, which took place several years ago, but seems as if it just happened.
On an afternoon several years ago, my brother-in-law opened the bottom drawer of my sister’s dress and picked out a beautiful skirt. “ Jan bought this the first time we went to New York, at least 8 or 9 years ago. She never wore it. She was saving it for a special occasion.” he said．I guess this was the occasion: it was the funeral of my sister, after her unexpected death.
He took the shirt and put it on bed, with the other clothes we were taking to the funeral. Then he closed the drawer and turned to me, “Don’t ever save anything for a special occasion. Every day you’re alive is a special occasion.”
I’m thinking about his words, and they’ve changed the way I live my life. I’m spending more time with my family and friends and less time in committee meetings. Whenever possible, life should be a kind of experience to enjoy, not to suffer. “Someday ”and “one of these days ”are losing their importance on my vocabulary. If it’s worth seeing or hearing or doing, I want to see and hear and do it now.
Ever since that day, I have been trying very hard not to put off, hold back or save anything that would add laughter and color to our lives. Every morning when I open my eyes, I tell myself that every day, every minute, every breath, truly is a gift. So cherish every day and find the true meaning of your life.Why did Jan buy the beautiful skirt but didn’t wear it?
| A．She waited for a special occasion to wear it on. |
| B．She wanted to keep it for someone else. |

A California family drives a car that could help protect the environment. When Jon and Sandy go to the store or to their daughters’ soccer games, they drive in high-tech style. They drive a $1 million, fuel-cell-powered car. It may be the world’s most expensive car and one of the most environmentally friendly cars. The FCX is the first fuel-cell-powered car to be used by a family anywhere in the world. The FCX uses hydrogen and oxygen for fuel. Car makers have been working to develop vehicles that are better for the environment. They are developing cars that use fuel other than gasoline. And then what is fuel cell technology? Fuel cell technology works by changing the chemicals hydrogen and oxygen into water. This process produces electricity, and water vapor which comes out of the exhaust pipe. Most cars release dangerous gases such as carbon monoxide and carbon dioxide. Many scientists say these gases are major contributors to global warming. “The FCX is driven just like any other vehicle on the road, but without the gases which pollute the environment,” scientists say. Fuel cell technology has been around since the 1800s, but scientists have yet been to perfect it. They say it may take years before the technology is ready for widespread use. Another earth-friendly car is already on the market. Hybrid cars use both gasoline and an electric motor. They are becoming more popular with customers because they cut pollution and improve fuel efficiency.Which of the following about the FCX is not true?
| A．It may be the most expensive car in the world. |
| B．It is one of the most environmentally friendly cars. |
| C．It releases dangerous gases to pollute the air. |
| D．It uses hydrogen and oxygen for fuel other than gasoline. |
According to the passage, what is the major cause for global warming?
| A．Gases from FCX. | B．Water vapor from cars. |
| C．Hydrogen and oxygen. | D．Gases from cars. |
From the passage, we know that fuel cell technology ______.
| A．works by water | B．has a history for over two hundred years |
| C．works by electricity | D．has been widely used since the 1800s |
We can infer from the passage that ______.
| A．future cars will be environmentally friendly |
| B．there will be no gasoline for cars |
| C．people can’t afford to buy cars in the future |
| D．global warming has been stopped |
Hybrid cars are popular because ______.

A "blogger" is a person who writes on an Internet computer Web site called a "blog". The word "blog" is a short way of saying Web log, or personal Web site. Anyone can start a blog, and they can write about anything they like.
There are millions of blogs on the Internet today. They provide news, information and ideas and many people read them. They contain links to other Web sites. And they provide a place for people to write about their ideas and react to the ideas of others.
A research company called Perscus has studied more than 300 Web logs . It says that blogs are most popular with teenage girls. They use them to let their friends know what is happening in their lives. The study also says that more than 100,000 bloggers stopped taking part in the activity after a year.
However, some people develop serious blogs to present political and other ideas. For example, the Republican and Democratic parties in the southern state of Kentucky recently started their own blogs. And American companies are beginning to use blogs to advertise their products.
At the same time, some long-standing blogs have ended last week, blogging leader Dave Winer closed his free blog service "weblogs. com". He says the site became too costly to continue. He started the blog four years ago. And thousands of people had written on it. They are now upset because they did not know that the site was closing.
One blog that is still going strong is called Rebecca's Pocket. Rebecca Blood created the Web-site in 1999. She wrote about the history of blogs on the site. That article led to a book called "The Weblog Handbook". It has been translated into four languages so far.
Ms. Blood says Rebecea's Pocket gets about 30,000 visitors a month. She writes about anything and everything--politics, culture and movies. She recently provided medical advice. And she wrote about how to prevent people from stealing money from on -line bank accounts. The author wrote this passage mainly to _________.
