The Asian elephant has been respected for centuries and is still used today for ceremonies and religious purposes. It is respected, not only because it plays a role in Asian culture and religion, but also because it is a key biological species in the tropical forests of Asia.

The Asian elephant is the largest land mammal in Asian. It is smaller than the African elephant, with relatively smaller ears. Asian elephants have a single “finger” on the upper lip of the long trunk, while African elephants have a second on the lower tip. A number of adult male Asian elephants have no tooth, and the percentage of males carrying ivory(象牙）is different from only about 5% in Sri Lanka to 90% in south India. Asian elephants keep their ears in constant motion in order to free the heat they produce. The species is reported to have well-developed hearing, vision, and smell , and they are also fine swimmers.

Asian elephants prefer to convey something to form groups surrounding 6 to 7 related females that are led by the oldest female. Like African elephants, these groups occasionally join others to form herds, although these associations are relatively temporary.

More than two thirds of the day may be spent feeding on grasses, but large amounts of tree bark, roots, leaves and small stems are also eaten. Crops such as bananas, rice and sugar plants are favored foods. Besides, they need to drink at least twice a day so the source of water is quite important.

The Asian elephant used to live from modern Irap and Syria to the Yellow River in China at first, but it is now found only from India to Vietnam, with a tiny population in the extreme southwest of China’s Yunnan Province. More than 100,000 Asian elephants may have existed at the start of the 20th century. The population is estimated to have fallen by at least 50% over the last 60-75 years.

1.What can we learn from Paragraph2?

A.The Asian male elephant is the largest animal in the world.

B.The population of Asian male elephants with ivory varies by district.

C.The Asian elephant has two “fingers” on the lips of the long trunk.

2.The Asian elephants are most likely to fed themselves______.

A. in a very large forest

3.What makes the author worried in the last paragraph?

A. That there are fewer and fewer Asian elephants.

B. That Asian elephants originally ranged more widely.

C. That Asian elephants may suffer some diseases.

D. That there was too much killing in the last century.

4.The passage introduces Asian elephants mainly in the aspects of ______.

I never knew how amazing it would feel to help a family 4,560 miles away from my home. I never knew how great an effect I could have on that single family.

From the moment I walked into French class, I knew almost instantly that I belonged there. My teacher, Madame Weiser, is a kind and caring woman, and is the person who started the interest within me to help a family abroad, no matter how many miles apart.

Back in 2011, my teacher traveled as a tourist to Maxi, a country settled in West Africa with a large French-speaking population. She didn’t expect to adopt an entire family, but fate had other plans. Madame met a nice man named Monsieur Diarra, a driver who had shown her the way through the dry lands of Mali.

Mali is now a war-torn country and unsafe for tourists to visit, leaving little work for taxi drivers. Madame Weiser realized how Monsieur Driarra’s family struggled on a daily basis, for he had a wife and four children to support as well as their grandmother, so she made a final decision to send the family as much money as she could raise every month.

Now, three years later, Madame Weiser has still kept up her fund, collecting money from family and friends as well as students to support the cause. It has become more than just my teacher donating to her adopted family abroad.

As president of French Club at my high school and a French Honor Society member, I decided that our club should work to raise money for the family in need. By washing cars, we raised over $1,000.

From my experience, I’ve learned that making an effort is worth more than anything. Its effect is priceless!

1. Why do taxi drivers have difficulty finding work in Mali?

A. People don’t like taking a taxi.

B. Tourists visiting Mali are few.

C. Mali is very unsafe for them.

D. Public transport is enough.

2. What does the underlined expression “the cause” refer to?

A. Teaching Trench in West Africa.

B. Looking for jobs for the drivers in Mali.

C. Helping the homeless as much as possible.

D. Donating money to the adopted family abroad.

3. What did the writer think of her experience?

A. Boring B. Puzzling

C. Satisfying. D. Relaxing.

4. What is the best title of this passage?

A. The Love for Africa. B. A Kind Foreign Driver.

C. My Helpful Teacher D. My Unforgettable Class

The evidence for harmony may not be obvious in some families. But it seems that four out of five young people now get on well with their parents, which is the opposite of the popularly held image of unhappy teenagers locked in their room after endless family quarrels.

An important new study into teenage attitudes surprisingly shows that their family life is happier than it has ever been in the past. “We were surprised by just how positive today’s young people seem to be about their families,” said one member of the research team. “They’re expected to be rebellious（叛逆的）and selfish but actually they have other things on their minds; they want a car and material goods, and they worry about whether school is serving them well. There’s discussion between parents and children, and children expect to take part in the family decision-making process. They don’t want to rock the boat.”

So it seems that these parents are much more likely than parents of 30 years ago to treat their children as friends. “My parents are happy to discuss things with me and willing to listen to me,” says 17-year-old Daniel LaSalle. “I always tell them when I'm going out clubbing. When they know what I'm doing, they’re fine with it.” Susan Cromer, who is now 21, agrees. “Looking back on the last 10 years, there was a lot of what you could call talk or discussion. For example, when I’d done all my homework, I could go out on a Saturday night. But I think my grandparents were a lot stricter with my parents than that.”

Maybe this positive view of family life should not be unexpected. It is possible that the idea of teenage rebellion is not based on real facts. A researcher explains, “Teenagers were thought to be different from others in a part of time in our social history. But to our surprise, they say they are getting on well with their parents. But that idea of rebelling and breaking away from their parents really only happened during that one time in the 1960s when everyone rebelled.”

1.The study shows that teenagers don't want to ______________________.

A. share family duties

B. cause trouble in their families

C. go boating with their family

D. make family decisions

2.Compared with parents of 30 years ago, today’s parents ___________________.

A. go to clubs more often with their children

B. are much stricter with their children

C. care less about their children’s life

D. give their children more freedom

3.According to the writer, teenage rebellion ____________________.

A. may be a wrong opinion

B. is common at present

C. always happened in the 1960s

D. was caused by changes in families

4.Which title best gives the main idea of the passage?

A. Discussion in family

B. Teenage education in family

C. Teenage trouble in family

D. Harmony in family

The world's first hamburger doesn't come from where you think it comes from. It wasn't invented in the United States, and it didn't originate in Germany. No, the world's first hamburger comes from China.

If you're scratching your head right now, you're not alone. But Chinese hamburgers are very real and they definitely predate the hamburgers we call our own in the U.S. Known as rou jia mo, which translates to "meat burger" or "meat sandwich", they consist of chopped meat inside a pita-like bun, and they've been around since the Qin Dynasty, from about 221 BC to 207 BC. Despite the differences between this Chinese street food and our American-style burgers, the rou jia mo has been called the world's first hamburger.

The rou jia mo originated in the Shanxi Province of China, and is now eaten all over the country. It's typically prepared and eaten on the street. The dough for the bun, or mo, consists of a simple mixture of wheat flour, water and maybe yeast. Of course recipes may vary, but this basic equation makes for a chewy and subtle pillow for the delicious filling. While the mo is traditionally baked in a clay oven, today it's often fried in a pan. They may look a little like Chinese steamed buns or baozi, but the dough for those are, of course, steamed, not baked or fried.

The meat filling might consist of chopped pork, beef, lamb or chicken that has been stewed with a variety of spices, like ginger, cloves, coriander and star anise. You might also find herbs like cilantro or greens like lettuce garnishing the sandwich.

1.What does the underlined word mean?

A. noodle B. food C. bread D. beverage

2.Which of the following is TRUE?

A. The mo people eat today is baked in a clay oven.

B. The world's first hamburger which was originated in the Shanxi Province of China is popular around the world.

C. The rou jia mo has a history of more than 2200 years.

D. The rou jia mo and American-style burgers share a similar cooking process.

3.What would be the best title for the passage?

A. Delicious hamburger

B. How to cook hamburger

C. Chinese invented hamburger

D. History of hamburger
