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 | B．the forest elephant |

People in the United States honor their parents with two special days：Mother’s Day, on the second Sunday in May, and Father’s Day, on the third Sunday in June. These days are set aside to show love and respect for parents. They raise their children and educate them to be responsible(有责任感的) citizens. They give love and care. These two days make us think about the changing roles of mothers and fathers. More mothers now work outside the home. More fathers must help with child care.
These two special days are celebrated in many different ways. On Mother’s Day people wear carnations. A red one symbolizes a living mother. A white one shows that the mother is dead. Many people attend religious services to honor parents. It is also a day when people whose parents are dead visit the cemetery(墓地). On these days families get together at home, as well as in restaurants. They often have outdoor barbecues for Father’s Day. These are days of fun and good feelings and memories.
Another tradition is to give cards and gifts. Children make them in school. Many people make their own presents. These are valued more than the ones bought in stores. It is not the value of the gift that is important, but it is “the thought that counts”. Greeting card stores, florists, candy makers, bakeries, telephone companies, and other stores do a lot of business during these holidays.Which of the following is NOT a reason for children to show love and respect for parents?______.
| A．Parents bring up children. |
| B．Parents give love and care to children. |
| C．Parents educate children to be good persons. |
| D．Parents pass away before children grow up. |
What do you think “florists”(in para.3) do?______.
| A．They sell flowers. |
| B．They make and sell bread. |
| C．They offer enough room for having family parties. |
| D．They sell special gifts for Mother’s Day and Father’s Day. |
What do you know from the passage?________.
| A．Mother’s Day and Father’s Day are both in May. |
| B．Fewer women worked outside the home in the past. |
| C．Not all the children respect their parents. |
| D．Fathers are not as important as mothers at home. |
Mark Twain was a great writer. He was from the USA. He was born in 1835. He was also a famous speaker. He was famous for his sense of humour. Many people liked to listen to him talk because he liked to tell some interesting stories to make people laugh all the time. One day Mark Twain was going to a small town because of his writing. Before he was going to leave, one of his friends said to him that there were always a lot of mosquitoes in the town and told him that he’d better not go there. Mark Twain waved (摇动) his hand and said, “It doesn’t matter. The mosquitoes are no relatives of mine. I don’t think they will come to visit me.”
After he arrived at the town, Mark Twain stayed in a small hotel near the station. He went into his room, but when he was just about to have a rest, quite a few mosquitoes flew about him. The waiters felt very sorry about that. “I’m very sorry, Mr. Mark Twain. There are too many mosquitoes in our town.” One of them said to him.
Mark Twain, however, made a joke, saying to the waiter, “The mosquitoes are very clever. They know my room number. They didn’t come into the wrong room.” What he said made all the people present laugh heartily.

To many students, high school is just a basic routine. You go to class in the morning, take a break for lunch and go home in the afternoon.
This isn't quite that simple for pupils at Royal West Academy. As if classes and homework weren’t already enough, students are also required to complete a range of extracurricular activities, or ECAs.
The range of ECAs being offered at the school is various, including everything from guitar and jewelry-making clubs, fund-raising marches, to student committees, swimming and tennis.
“I love ECAs. I’m so happy we have them,” said grade 11 student Adrienne, who is a soccer player and member of the graduation committee. “They motivate the students, and they’re a great bonding experience. I think that without them, not half as many students would be joining up for the soccer team.”
Requiring students to complete ECAs is a sign of the times. That’s because young people are preparing for the future in ways that weren’t considered necessary before. This is an era when ECAs are seen as important. Whether it’s for leadership experience, sports, craft skills or volunteer these things are seen as rounding out the individual and improving their future.
ECAs can also help students discover their likes and dislikes. But as the old song says, you can’t always get what you want, especially when so many students are all trying to sign up for the most popular activities.
ECAs can cut into study and homework time if you’re not careful. You really have to get organized or you’ll fall apart.The students at Royal West Academy may do the following ECAs except ______.
| A．to play musical instruments |
| B．to raise money for an organization |
| C．to attend sports events |
| D．to have classes discussions |
From what Adirienne said, we know that _______.
| A．most of his classmates are interested in football |
| B．one can make many new friends in ECAs |
| C．students get encouraged to join in ECAs |
| D．half of his classmates are unwilling to join in ECAs. |
Why are ECAs important now?
| A．They prepare the students for their future. |
| B．They can make students get what they want. |
| C．they can help students find their strong points. |
| D．They can reduce students’ learning time. |
From the last paragraph, we can infer that _______.
| A．ECAs can increase your burden of learning |
| B．you may fall down when playing in ECAs |
| C．too many ECAs may leave you in trouble |
| D．you need to organize other students in ECAs |
