[1] One out of many important things for the whole family to do is to have dinner together. Researchers began reporting the benefits of family dinner about a decade ago, focusing mainly on how it affects children. Studies show that those families who eat dinner at least 3 or 4 times a week together, benefit in many ways.

[2] Eating together helps families achieve open communication and build stronger and healthier relationships. Children have better grades at school and are better adjusted as teens and adults, and the entire family enjoys healthier nutrition. For many families, eating dinner together proves to be a good and effective way to reduce the risk of youth rates of addiction, and helps to raise healthier children. It is also a great time to share the events of the day, discuss news and ideas and just be together and enjoy each other's company.

[3] During dinner time parents have better opportunity to show that they are the prior to their children. Sitting at the same table and sharing meals is where and when parents can find out more about their children's school performance, daily activities and attitudes toward life. When parents have all this information they can better direct their kids toward positive things in life. They also have better chance to reduce the possibility that children will get involved with alcohol, tobacco, and illegal drugs.

[4] However, family researchers say that the benefits of family dinner by no means can be considered as automatic. Parents can sit down to dinner with their kids every day and achieve nothing. ______ if there is too much arguing going on, if there is no meaningful conversation or, what is even worse, if there is just plain silence during gathering.

2.List two benefits that parents can get by having dinner together with children.(no more than 15words).

3.Fill in the blank in Paragraph 4 with proper words (no more than 8 words).

5.What does the word “it” (line 3, paragraph 1) probably refer to? (no more than 3 words)

Recently there was a major discovery in the scientific research—the mapping of all DNA in a human gene（基因） is complete．Couple of years ago, this seems an impossible task for scientist to accomplish．All this progress in science leads us to believe that the day, when the human being will be cloned, is not far away．Human cloning has always been a topic of argument, in terms of morality or religion．

Taking a look at why cloning might be beneficial, among many cases, it is arguable that parents who are known to be at risk of passing a genetic limitation to a child could make use of cloning．If the clone was free of genetic limitations．then the other clone would be as well．The latter could foe inserted in the woman and allowed to ripen to term．Moreover, cloning would enable women, who can't get pregnant, to have children of their own．

Cloning humans would also mean that organs could be cloned, so it would be a source of perfect transfer organs．This, surely would be greatly beneficial to millions of unfortunate people around the world that are expected to lose their lives due to failure of single （or more） organ （s）．It is also arguable that a ban on cloning may be unlawful and would rob people of the right to reproduce and limit the freedom of scientists．

Arguments against cloning are also on a perfectly practical side．Primarily, I believe that cloning would step in the normal "cycle" of life．There would be a large number of same genes, which reduce the chances of improvement, and, in turn, development—the fundamental reason how living things naturally adapt to the ever-changing environment．Life processes failing to do so might result in untimely disappearance．Furthermore, cloning would make the uniqueness that each one of us possesses disappear．Thus, leading to creation of genetically engineered groups of people for specific purposes and, chances are, that those individuals would be regarded as "objects" rather than people in the society．

Scientists haven't 100 per cent．guaranteed that the first cloned humans will be normal．Thus this could result in introduction of additional limitations in the human "gene-pool"．

Regarding such arguable topics in "black or white" approach seems very innocent to me personally．We should rather try to look at all "shades" of it．I believe that cloning is only legal if its purpose is for cloning organs; not humans．Then we could regard this as for "saving life" instead of "creating life"．I believe cloning humans is morally and socially unacceptable．

1.Which of the following is true according to the passage?

A．Genetic limitation will be beneficial for some women

B．A large number of genes will prevent us from developing

C．Prohibition of cloning might limit the freedom of scientists

D．First cloned humans might be normal according to scientists

2.What's the author's opinion on cloning?

A．Cloning should be entirely banned．

B．Cloning should be used in creating life．

C．Cloning will take away the right to reproduce．

D．Cloning is acceptable if it is used for cloning organs．

3.Where can you read this article?

A．In a story book

B．In a magazine

4.Which of the following shows the structure of the passage?

Peter and his seven-year-old sister ,Kate , were at the same school. Not long after his tenth birthday Peter was entrusted to take her to school.

It was only two stops down the road , but the way his parents kept going on about it , you might have thought Peter was taking Kate to the North Pole . He was given instructions the night before. When he woke up , he had to listen to them over and over again. He was to keep hold of Kate’s hand at all times , sit close to the front nearest the window , and tell the bus driver the name of his stop.

Peter repeated all this back to his mother and set out for the bus stop with his sister. They held hands all the way. Actually he didn’t mind this but simply hoped that none of his friends would see him holding a girl’s hand. The bus came. They got on and sat close to the front. It was ridiculous sitting there holding hands and there were some boys from school there, so they let go of each other.

Peter was feeling proud of himself. He could take care of his sister anywhere. If they were alone tighter on a mountain pass and came face to face with a pack of hungry wolves, he could know exactly what to do. Taking care and not to make sudden movement, he would move away with Kate until they had their backs to a large rock. That way the wolves would not be able to surround them.

Then he takes from his pocket two important things—his hunting knife and a box of matches. He takes the knife from its sheath(鞘) and sets it down on the grass, ready in case the wolves attack. They’re coming close now. They’re so hungry and are watering and growling (咆哮). Kate is crying, but he cannot comfort her. He knows he has to concentrate on his plan. Right at their feet are some dry leaves and twigs. Quickly and skillfully, Peter gathers them into a small pile. The wolves are edging closer. He has to get this right. There’s only one match left in the box. He bends down, cups his hand and lights the match. There’s strong rush of wind. The flame flickers, but Peter holds it close to the pile and then first one leaf, then another, then the end of a twig catch fire, and soon the little pile is burning. He piles on more leaves and twigs and larger sticks. The wolves are backing off. Wild animals are terrified of fire. The flames are leaping higher and the wind is carrying the smoke right into their jaws. Now Peter takes holds of the hunting knife and …

Ridiculous! A daydream like this could make him miss his stop if he wasn’t careful. The bus had come to a halt. The kids from his school were already getting off. Peter leaped to his feet and just managed to jump to the pavement as the bus was starting off again. It was more than fifty yards down the road when he realized he had forgotten something. Was it his backpack ? No. It was his sister. He had saved her from the wolves and left her sitting there. For a moment, he couldn’t move. He stood watching the bus pull away up the road. “Come back,” he murmured, “Come back.”

The porter brings your bags to your room and helpfully explains all you want to know. Then he points to the phone and says, “If there's anything else you need, just call.” All this time you have been thinking one thing, “How much should I tip(付小费) him?” To make your next trip a little easier, here's a guide to tipping across some Asian countries.

Bangkok

In general, the more Westernized the place is, the more likely you will be expected to leave a tip. Some top-end restaurants will add a 10% service charge to the bill. If not, waiters will appreciate you tacking on(附加) the 10% yourself. However, if you're eating at a lower-end(低档的) restaurant a tip is not necessary. If you're staying at one of Bangkok's many five-star hotels, expect to tip the porter 20 to 50 baht(泰国货币单位), depending on how many bags you have. Taxis are now metered in Bangkok. Local custom is to round the fare(车费) up to the nearest five baht.

Hong Kong

Tipping is customary in this money-mad metropolis(大都市). Most restaurants add a 10% service charge to the bill, but the extra money often ends up in the pocket of the owner. If the service is good, add another 10% to the bill, up to HK $100 in an especially nice restaurant. For HK $10 hotel porters should do it at all but the nicest hotels where a new HK $20 bill may be more acceptable. When in a taxi, round up(凑整数) to the nearest dollar.

Kuala Lumpur

Tipping in Malaysia is limited to the expensive Westernized hotels, which often add a 10% service charge to your meal or hotel room. If you are at a hotel restaurant, expect a 10% service charge. But at local restaurants, there's no need to add a tip. At five-star hotels, one or two ringgit(马来西亚货币单位) will content a porter. At lower-end buildings don't feel you have to tip. Like Bangkok, many taxis are now metered so you can just round up to the nearest ringgit.

Seoul

Tipping is not part of Korean culture, although it has become a matter of course in international hotels where a 10% service charge is often added. If you're at a Korean barbecue joint(烧烤处), there's no need to add anything extra. But a nice Italian restaurant may require a 10% contribution. If you're at a top-end hotel, so expect to pay 500～1 000 won per bag. Taxi drivers don't accept a tip. Keep the change for yourself.

1.In which of the following cities is it unnecessary to tip the taxi-drivers?

A．Bangkok. B．Hong Kong. C．Seoul.. D．Kuala Lumpur

2.Which of the following is NOT the unit of money?

A．Baht B．Charge. C．Won. D．Ringgit.

3.From the text, we can infer tipping comes from _______.

A．the west B．Hong Kong C．Asian countries D．Bangkok

4.If you stay at a five-star hotel in Kuala Lumpur, how much will you pay the porter at least?

A．one ringgit. B．10% of service charge C．half a ringgit. D．two ringgit.

5.The writer seems _______.

A．to give the readers some advice on how to tip B．to tell the readers how to travel

C．to ask the readers to go on a travel to Asian cities D．to make the trip more pleasant
