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 |
C.the savanna elephant | D.the mastodon elephant |
The underlined word “divergence” in paragraph 4means “________”
A.evolution | B.exhibition | C.separation | D.examination |
The researcher’s conclusion was based on a study of the African elephant’s ____________
A.DNA | B.height | C.weight | D.population |
What were Alfred Roca’s words mainly about?
A.The conversation of African elephants. |
B.The purpose of studying African elephants |
C.The way to divide African elephants into two units |
D.The reason for the distinction of African elephants |
Which of the following can be the best title for the passage?
A.Naturalist’s Belief about Elephants. |
B.Amazing Experiment about Elephants |
C.An Unexpected Finding about Elephants |
D.A Long scientific Debate about Elephants |

We all know, especially for me who like travelling very much, travelling can be a way to gain life experiences, especially during Spring Break----a week long school vacation in the United States. But what if you’re a student and don’t have enough money for a trip? Don’t worry. Here are some useful suggestions.
Save: this probably is the most important preparation for travelling. Cut expenses to fatten your wallet so you’ll have more choices about where to go and how to get there.
Plant ahead: Don’t wait until the last minute to plan your trip. Tickets may cost more when bought on short notice. Giving yourself several months to get ready can mean security(安全) and saving.
Do your homework : No matter where you go, research the places you will visit. Decide what to see. Travel books will provide information on the cheapest hotels and restaurants.
Plan sensibly, Write down what you expect to spend for food and hotels. Stick to your plan or you may not have enough money to cover everything.
Travel in groups: Find someone who is interested in visiting the same places. By traveling with others you can share costs and experiences.
Work as you go: Need more money to support your trip? Look for work in the places you visit.
Go off the beaten path: Tourist cities may be expensive. You may want to rethink your trip and go to a lesser-known area. Smaller towns can have many interesting act ivies and sights.
Pack necessary things: The most important things to take are not always clothes: Remember to take medicine in case you get sick and snacks in case you cannot find a cheap restaurant.
Use the Internet: The Net can help to save money. Some useful websites include www.Travelocity.com. www.bargains-lowestfare.cm and www.Ecoomictravel.co
By planning sensibly, even students can enjoy the travel. Your travel experiences will be remembered for a lifetime.

When I recall my experiences of feeling heard and deeply understood by someone, I know how much the experiences helped me to cope with whatever I was dealing with at the time. Caring people who I have turned to in difficult times helped me the most by listening and asking about my feelings.
During one of my volunteer jobs at a local HIV and cancer clinic, I found the helpfulness of empathic(感情移入的) listening. As a volunteer I was providing emotional support for people with health related problems. Empathic listening really made a difference on how patients felt about their health problems. By sharing about their pain and suffering and may willingness to listen, they felt less alone.
We can make life easier for each other by becoming a better listener and encouraging each other to share our feelings. We can become a better listener by avoiding giving advice and trying to solve problems unless we are asked to do so. Pressuring others to solve their life problems--"our ways"--is not helpful. Most people intuitively(凭直觉地) know how to solve their own problems. As a listener it's important to be patient and not to interrupt the speaker. Let them know it's OK to talk about their feelings and support them in feeling their feelings.
When one neither shares nor reaches out for support, he or she can remain a lonely mystery. Life can feel lonely when one keeps everything inside. Feeling alone with life problems can be worse than the problem itself. When we let a caring person listen to our life struggle, we will no longer feel alone with our struggle. Don't be afraid to ask your loved ones to take time to hear you out. Sometimes you have to ask for it. People cannot read your mind. Confiding in others can have a positive effect on our mood.
59.What made the author comfortable in difficult times?
A. Persuading B. Sharing C. Apologizing D. Complaining
60.According to the second paragraph, we can know that ____.
A. The patients enjoyed listening to the author
B. The author found empathic listening was helpless
C. The patients didn't get on well with the author
D. The author did a good job at a cancer clinic
61.What does the underlined part "Confiding in others" in the last paragraph mean?
A. Telling others your secrets. B. Reading others' mind
C. Listening to others. D. Leaving others alone.
62.What's the main idea of this passage?
A. Listening and sharing can make you happier.
B. People know how to solve their own problems.
C. It is wrong to give advice to solve problems.
D. You should learn to believe in other people.

阅读下列短文,从每题所给的四个选项(A,B,C,D)中,选出最佳选项。
Mike McClure walked into Sarasota Bay for a little fishing on a beautiful day last April. This afternoon, the water was shallow enough at low tide that McClure could easily walk 100 yards offshore and cast(投)his line in any direction.
Near sunset, still without a fish, he decided to turn back. Rather than turn to his earlier course, he chose a more direct path toward shore, thinking the bay wouldn't get deeper along the way. Instead, he was trapped. He tried to walk in different directions, but shallower water eluded(避开)him. Finally, he decided his safest choice was to head straight for land.
"Within about five steps, the water was coming in through the top of the waders(高筒防水胶靴)," says McClure.
He felt the deadweight of the flooding waders pulling him down and knew that if he didn't get out of them, he would drown. But he failed to kick his way out of the waders. Instead, they pulled him completely below the surface.
Back onshore, Eliza Cameron, 19, Loren Niurka Mora, 20, and Caitlin Petro, 20, had been watching McClure fish as they rested on the grass after a long week of classes. They saw McClure go under and then heard him cry, "Help!”
The three friends kicked off their shoes and ran into the bay. They were all good swimmers, but all hid a fear that he might pull them down too because they'd have to dive to save him.
When they reached him, he'd managed to kick himself out the waders, but his eyes had partly rolled back. Cameron and Mora each hooked an arm under his shoulders, while Petro supported his back and held his hand. Then the three friends tried their best to tug him towards shore. Finally, they all returned to shore safely.
56.Mike McClure didn't turn back by his earlier course because _____.
A. He wanted to choose a short course
B. His earlier course was dangerous
C. He just wanted to take a risk
D. He knew where the water was deep
57.What directly trapped Mike McClure in the bay?
A. His wrong decisionB. The coming high tide
C. His waders' being flooded D. The depth of water
58.During the rescue, ____.
A. The three women were afraid of being trapped in the water
B.Cameron and Petro helped catch Mike McClure's arms
C. The three women removed Mike McClure's waders
D. Mike McClure still wore his flooding waders
