The weather is getting hotter. You are thirsty playing basketball or riding home from school. A cold drink may be just the thing. But be careful what you are drinking. Something that looks cool may not be good for your health.

There are plenty of "energy drinks" on the market. Most of them have beautiful colors and cool names. The lists on them tell you they are helpful to your health. Sounds great!

But after a careful check you may find that most energy drinks have lots of caffeine (咖啡因) in them. These drinks are especially aimed at young people, students, busy people and sports players. Makers sometimes say their drinks make you better at sports and can keep you awake. But be careful not to drink too much.

Caffeine makes your heart beat fast. Because of this, the International Olympic Committee has limited( 限制) its use. Caffeine in most energy drinks is at least as strong as that in a cup of coffee or tea. Possible health dangers have something to do with energy drinks. Just one box of energy drink can make you nervous, have difficulty sleeping and can even cause heart problems. Scientists say that teenagers should be discouraged from taking drinks with a lot of caffeine in them.

Who needs guard dogs when you have wolves , right? That’s probably what Kazakh villagers in the Almaty region though when they decided to replace their dogs with the fierce forest dwelling beasts. According to local news reports, taming(馴化的) wolves is now the latest trend and a sort of hobby among rural Kazakhs.

Nurseit Zhylkyshybay, a farmer from the south-eastern Almaty region, told reporters that he purchased a wolf cub from hunters three years ago, and the animal is now perfectly tamed.

Kurtka, Nurseit’s pet wolf, lives in the family’s yard and takes long walks through the village with his master. “He’s never muzzled,” Nurseit insisted. “I rarely put him on a chain and do take him for regular walks around the village. Our family and neighbors aren’t scared of him at all.”

But wolf expert Almas Zhaparov said that the animals are ‘far too dangerous’ to keep at home. “A wolf is like a ticking bomb, it can go off at any moment,” he warned. “If nothing is done, the fashion could spread to the wealthy Kazakhs, who might try to keep wolves in the grounds of their houses, with possibly deadly consequences.” Social media users also expressed worry about the trend, accusing the government for failing to limit the practice.

Nevertheless, the wolves don’t seem to be posing an immediate threat. If visuals from news reports are anything to go by, the beasts look pretty happy with their new lifestyle, and appear quite fond of their new masters, not unlike dogs.

1.The writer uses the example of Kurtka to show that____________.

A. wolves can be tamed.

B. wolves are like ticking bombs

C. wolves like living with humans

D. keeping wolves at home is easy

2.The underlined word “muzzled” in Para 3 means___________.

A. puzzled B. beaten

C. got his mouth covered D. got changed

3.According to Almas Zhaparov, keeping wolves at home is___________.

A. a fashion B. a disaster

C. a necessity D. a hone

4.What can we learn from the text?

A. Wolves are easy to get tamed.

B. A pet wolf can become aggressive at any moment.

C. The government will prevent people taming wolves as pets.

D. Wolves are as loyal to their masters as dogs are.

There is a problem discussed by people about whether parents should hit their children? Or should they ever beat them?

Research suggests many of us are likely to respond “no”, and public support for spanking（打屁股）has been falling over the years. But surveys also show that 75 percent to nearly 90 percent of parents admit to spanking their child at least once.

I was raised in a zero-tolerance home for disrespect, and my parents often turned to physical punishment. And, no, I don’t feel I was damaged by it.

Nothing is more annoying than watching ill-mannered behavior from children.

But there is data to suggest that a return to old-school spanking isn't the answer.

Two years ago, Newsweek reported that it had found data suggesting that teens whose parents used physical punishment were more likely to become aggressive.

Murray Straus, professor at the University of New Hampshire in America, has studied the topic of children and spanking for decades. He said that children who were physically punished have lower IQs than their peers. It may be that children with lower IQs were more likely to get spanked, but the punishment may have been counterproductive（反作用的）to their mental development, as well.

Some researchers make the argument that occasional open-handed smacks（用巴掌打）on the bottom are not only harmless but can have some benefit.

Last year, Marjorie Gunnoe, a psychologist at Calvin College, studied teens who have never been spanked. There are a greater number of children growing up without ever having been physically punished. Gunnoe’s research suggests they don’t turn out any better than those who were sometimes spanked.

There are some parents who simply cannot control their tempers（脾氣）. But I still believe that the best parents are the ones who are able to offer fair and firm discipline without ever turning to physical punishment.

1.According to the first three paragraphs, the author was probably hit by her parents when __________.

A. they were dissatisfied with her grade

B. they cannot control their temper

C. she showed no respect for the elder

D. their discipline turns out to be not strict enough

2. According to Murray Straus, children who are physically punished __________.

A. are less aggressive toward others when they get older

B. may develop lower IQs than their peers

C. benefit from occasional spanking

D. have slower physical development

3.The author seems to agree that __________.

A. parents should determine whether a child needs to be smacked or not

B. children who have been spanked tend to behave better than those who haven't

C. physical punishment should be the last resort （手段）of any parent

D. good parents discipline their children in a fair and reasonable way

The most frightening words in the English language are, “Our computer is down.” You hear it more and more when you are on business. The other day I was at the airport waiting for a ticket to Washington and the girl in the ticket office said, “I’m sorry, I can’t sell you a ticket. Our computer is down.”

“If your computer is down, just write me out a ticket.”

“I can’t write you out a ticket. The computer is the only one allowed to do so.”

I looked down on the computer and every passenger was just standing there drinking coffee and staring at the black screen. Then I asked her, “What do all your people do?”

“We give the computer the information about your trip, and then it tells us whether you can fly with us or not.”

“So when it goes down, you go down with it.”

“That’s good, sir.”

“How long will the computer be down?” I wanted to know.

“I have no idea. Sometimes it’s down for 10 minutes, sometimes for two hours. There’s no way we can find out without asking the computer, and since it’s down it won’t answer us.”

After the girl told me they had no backup(備用) computer, I said. “Let’s forget the computer. What about your planes? They’re still flying, aren’t they?”

“I couldn’t tell without asking the computer.”

“Maybe I could just go to the gate and ask the pilot if he’s flying to Washington, ” I suggested.

“I wouldn’t know what gate to send you to. Even if the pilot was going to Washington, he couldn’t’t take you if you didn’t’t have a ticket.”

“Is there any other airline flying to Washington within the next few hours?”

“I wouldn’t know,” she said, pointing at the dark screen. “Only ‘IT’ knows. ‘IT’ can’t tell me.

By this time there were quite a few people standing in lines. The word soon spread to other travelers that the computer was down. Some people went white, some people started to cry and still others kicked their luggage.

1.The best title for the article is _______.

A. When the Computer Is Down

B. The Most Frightening Words

C. The Computer of the Airport

D. A different travel

2.What could the girl in the ticket office do for the passengers without asking the computer?

A. She could sell a ticket.

B. She could write out a ticket.

C. She could answer the passengers’ questions.

D. She could do nothing.

3.Why do you think they had not a backup computer?

A. Because it was easy down

B. Because it was not relied on .

C. Because it was not useful.

D. Because it was very expensive.

4.The last paragraph suggests that _______.

A. a modern computer won’t be down.

B. computers can take the place of humans

C. sometimes a computer may bring suffering to people

D. there will be great changes in computers

5.What kind of feeling did passengers have when the computer was down?

A. upset B. determined

C. encouraged D. happy

Living with other students can be a wonderful experience. Here are a few tips for student accommodations that can help ensure a great experience and build lifelong friendships: Screen your roommates carefully if you are given a choice. Combining the living spaces of several students into one location can be exciting and rewarding experience for the outgoing students.

Think about someone else before you think about yourself. Put your roommates interests above your own. Life will be far enjoyable when everyone is concerned about the feelings property and studies of each other.

Be open and honest. Hostilities (敵意) and frustrations may cause problems that can’t be fixed. Everyone brings different standards and expectations to group living and it’s in everyone’s best interest to put them into the open. Disagreements can be managed more warmly when your are willing to be both open and listen to others.
