Among all the fast growing science and technology, the research of human genes, or biological engineering as people call it, is drawing more and more attention now. Sometimes it is a hot topic discussed by people.

The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing with, such as cancer and heart disease. Every year, millions of people are murdered by these two killers. And to date, doctors have not found an effective way to cure them. But if the gene technology is applied, not only these two diseases can be cured completely, bringing happiness and more living days to the patients, but also the great amount of money people spend on curing their diseases can be saved, therefore it benefits the economy as well. In addition, human life span (寿命) can be prolonged.

Gene technology can help people to give birth to more healthy and clever children. Some families, with the English imperial (皇家的) family being a good example, have hereditary diseases. This means their children will for sure have the family disease, which is a great trouble for these families. In the past, doctors could do nothing about hereditary diseases. But gene technology can solve this problem perfectly. The scientist just need to find the wrong gene and correct it, and a healthy child will be born.

Some people are worrying that the gene research can be used to manufacture human beings in large quantities. In the past few years, scientists have succeeded in cloning a sheep, therefore these people predict that human babies would soon be cloned. But I believe cloned babies will not come out in large quantities, for most couples in the world can have babies in very normal way. Of course, the governments must take care to control gene technology.

1.What does “them” in the second paragraph refer to ?

A. People with cancer or heart disease.

B. Millions of people with serious diseases.

C. Some diseases doctors can do nothing with.

D. The two illnesses of cancer and heart disease

2.What can gene technology do according to paragraph three?

A. It can help the English imperial family out.

B. It can be used to clone human babies.

C. It can help people to give birth of a baby.

D. It is likely to treat hereditary diseases.

3.What are people worried about according to the passage?

A. Human babies may be cloned in a large scale.

B. Healthy human babies will soon be cloned.

C. Scientists may well find the wrong genes.

D. The government may not control gene techs.

4.This passage is mainly written to _________________.

A. show gene technology will benefit people

B. show gene technology will do harm as well

C. tell that gene technology is a hot topic

D. tell that gene technology is growing fast

Maddie Messe, 13, has always loved Temple Run, a mobile game that sends her racing through swamps (沼泽) and forests to outrun a pack of crazed monkeys. What she didn’t love was being forced to play as a boy — unless she was willing to buy a female version. “I felt like l was being cheated or misrepresented,” Maddie explains.“Girls are just as capable (有能力的) of running away from monkeys as boys are.”

So last winter, Maddie researched 50 of the most popular iPhone games. What she found was infuriating:90 percent offered free male characters, but only 15 percent let you play as a female for free.

Armed with those statistics, Maddie drafted a spirited article and fired it off to several major newspapers. The Washington Post agreed to run the piece, which attracted millions of readers around the globe — including the makers of Temple Run! “We realized she had a point,” says Natalia Luckyanova, the game’s co-creator. “It was the kick in the pants we needed to say,‘We should fix it.’So we did.”

Now you can play Temple Run with a female character for free, but Maddie hopes her campaign inspires something deeper.“If you don’t see characters that look like you on TV or in movies or games, speak up! Just do your research first,”says Maddie. “One well-supported argument is much more effective than a million angry complaints.”

1.What did Maddie hate about Temple Run?

A. It had no female versions.

B. It charged for female versions.

C. Its female versions were too expensive.

D. Its female versions were not good enough.

2.Maddle’s findings_________.

A. pleased her B. cheated her

C. angered her D. comforted her

C. impractical D. unreasonable

4.Maddie encourages readers to_________.

A. play mobile games within limits

B. write articles for major newspapers

C. respond to complaints in a proper way

D. do some research before making an argument

“Keep out or I’ll chase you out! This is my property!”

You hear this every spring. It is a long musical sound --- a bird song! Birds use their songs to communicate different messages to one another. People who study bird sounds are learning their meanings.

Usually it is the male that sings. Early in spring he sings to say that he has picked out a piece of property. He sings to attract a female of his same kind. Together they will raise a family in his territory (领地). He sings to tell all other birds of his kind to keep out.

Each kind of bird has its own type of song. Cardinals sing something that sounds a little like “What cheer, cheer, cheer.” Towhees sing, “Drink your tea.”

Most of the time, birds pay attention only to the songs of birds of their own kind. Cardinals answer cardinals, and song sparrows answer song sparrows. A cardinal knows that a song sparrow will not try to steal its mate. So you can see one reason why a cardinal may chase away another cardinal but will not bother a song sparrow.

Most different kinds of birds eat different things. To find enough to eat, a bird needs a big piece of land to search in. Many kinds of birds have some ways of dividing up the land into territories. Song sparrows, cardinals ovenbirds, and white-throated sparrows are some of the birds that have territorial systems.

Especially in early spring, birds work out the boundaries between their territories by singing “keep out” threats and by chasing and fighting each other. The birds continue singing to tell females that they have set up territories. Neighboring birds seem to agree that there are make believe fences between their pieces of property. Then they do not have to waste energy chasing each other instead of taking care of their young.

Scientists guessed that some birds could recognize their neighbors by small differences in their songs. Two scientists who studied white-throated sparrows found that these birds can even tell the difference between songs of individual birds of their own kind. White-throated sparrows have songs that seem to say “I’m your neighbor” or “I’m a stranger” or “I’m your neighbor to the west.” Other kinds of birds could tell neighbors from strangers by their songs, too.

A. they don’t need to fight or chase each other

B. they often work together against threats

C. they build up fences to protect their property

D. they find a big piece of land to search for food

4.What can we conclude from the article?

A. Male birds use their songs to communicate more than females.

B. Scientists have learned the meanings of all white-throated sparrows sing.

C Not all birds can recognize their neighbors by small differences in their songs.

D. White-throated sparrows are the smartest birds the scientists ever found.

I was on vacation, and in my mind, vacation does not mean setting my hotel room alarm clock for 6 am. But when you’re in Aruba and hoping to reserve a beachside palapa(简陋草棚), that’s exactly what you do.

Tourists begin lining up at the crack of dawn to secure these umbrella-like wood structures that are covered with dried and woven palm leaves. They then place towels on chairs and call them theirs for the day, whether they remain there or not. I knew nothing of this beach code of ethics on my first day in Aruba. I saw an empty chair covered with a towel and took it. It was a big mistake.

For many visitors, a week bathing in the sun is the only activity they wish to pursue. It sounded good to my girlfriend, Barbara, and me after Boston’s awful winter. Six more inches of snow was predicted on the day we left. The sun, the sand, and the beach seemed just about right.

Aruba’s slogan is “One Happy Island”, and it doesn’t take long to understand why. Aruba is said to be on “island time”. Translation: No one is in a rush to do anything. When in Aruba, you go with the flow, however slow and lazy that might be.

Cooling trade winds, white sandy beaches, turquoise(蓝绿色)waters, and dazzling sunsets are all good reasons to visit. But this 20-mile island offers more than lazy days walking on the beach. There is amazing night life, casinos, golf, scuba diving(水肺潜水), fine dining, shopping, and a great national park.

But our first day was spent as you’d expect, swimming in the sea and enjoying cool drinks. Our drink of choice quickly became the Coco Loco. It’s as refreshing as it sounds.

1.Tourists get up at 6 am because they _____.

A. want to see the sunrise early

B. need to check out early

C. want to have fun longer

D. need to reserve a beachside palapa

2.What does the underlined part in Paragraph 2 refer to ?

A. Using whatever chair you like.

B. Waiting in a long line for a palapa.

C. Taking up a chair by placing a towel on it.

D. Covering a palapa with woven palm leaves.

3.Paragraph 4 shows life in Aruba is very _____.

A. relaxing B. expensive

C. frightening D. disappointing

4.What did the author do on his first day there ?

A. He went shopping.

B. He swam in the sea.

C. He went scuba diving.

D. He visited a national park.
