“An apple a day keeps the doctor away.” Similarly, if we drink a little more water ever day, we may find that we need to go to the doctor a lot less often. A healthy diet is made up of water and a great many different kinds of foods. We know that healthy foods like fruits, vegetables and fish, are important as they provide us with energy and fibre, without giving us too much fat and sugar. But why is water important?
The human body needs water to survive. Water is important as it carries poisons and waste out of our bodies. However, doctors advise us to drink plenty of water, much more than the small amount we need to stay alive.
Some doctors believe that water is important for our health in all kinds of ways. They believe that a great many illnesses and health problems stars as a result of dehydration—a lack(缺少) of water in the body. Most people are dehydrated at least some of time, although they probably don’t know it. It is surprising to learn that if we feel thirsty, we are already in the first stages of dehydration. In fact, we are advised to drink water before we feel thirsty.
These doctors think that health problems such as headaches, high blood pressure and asthma could be helped if people drink more water. They also believe that drinking more water can help people who are overweight. Water contains no calories so it will not make us put on weight. If we drink water, we will probably drink less sugary soft drinks such as Coca-cola. Doctors also believe that drinking more water may stop people from overeating. They say that many people think that they are hungry when they are, in fact, thirsty. Doctors suggest, therefore, that we eat less food and drink more water.
There are still many health problems that cannot be solved by drinking water, so we should not stop going to seeing the doctor completely. However, if we make a decision to drink water every day, we may find that we need to go to the doctor a lot less often.
We need _____for a healthy diet.

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

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

Which of the following is NOT the unit of money?

A.Baht B.Charge. C.Won. D.Ringgit.

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

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

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.

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

Son’s Help
Mr. Lang worked in a factory. As a driver, he was busy but he was paid much. His wife was an able woman and did all the housework.

Long bus rides are like television shows. They have a beginning, a middle, and an end with commercials thrown in every three or four minutes. The commercials are unavoidable. They happen whether you want them or not. Every couple of minutes a billboard glides by outside the bus window. "Buy Super Clean Toothpaste.” Drink Good Wet Root Beer.” Fill up with Pacific Gas.” Only if you sleep, which is equal to turning the television set off, are you spared the unending cry of "You Need It! Buy It Now!"
The beginning of the ride is comfortable and somewhat exciting, even if you’ve traveled that way before. Usually some things have changed new houses, new buildings, sometimes even a new road. The bus driver has a style of driving and it’s fun to try to figure it out the first hour or so. If the driver is particularly reckless (鲁莽的) or daring, the ride can be as thrilling (惊心动魄的) as a suspense story. Will the driver pass the truck in time? Will the driver move into the right or the left hand lane? After a while, of course, the excitement dies down. Sleeping for a while helps pass the middle hours of the ride. Food always makes bus rides more interesting. But you’ve got to be careful of what kind of food you eat. Too much salty food can make you very thirsty between stops.
The end of the ride is somewhat like the beginning. You know it will soon be over and there’s a kind of expectation and excitement in that. The seat of course, has become harder as the hours have passed. By now you’ve sat with your legs crossed, with your hands in your lap, with your hands on the armrests even with your hands crossed behind your head. The end comes just at no more ways to sit.

They may be just passing your office, computer bag slung (悬挂) over one shoulder. Or they may be sitting in a car outside it, causally tapping away at a laptop. They look like innocent passers-by. In fact, they are stealing your corporate secrets.
Drive-by hacking is the trendy term given to the practice of breaking into wireless computer networks from outside the buildings that house them. A recent study in the UK, sponsored by RSA Data Security, found that two-thirds of organizations with wireless networks were risking their data in this way. Security experts patrolled (巡逻) several streets in the City of London seeking evidence of wireless networks in operation.
Of 124 that they identified, 83 were sending data without encrypting(加密)them. Such data could readily be picked up by a passer-by armed only with a portable computer, a wireless modem and a few pieces of software that can be freely downloaded from the Internet.
The data could include sensitive company documents containing valuable information. Or they could be e-mail identities and passwords that could be used by hackers to log into corporate networks as if they were legal users.
Most companies using wireless networking technology do not take even the simplest of measures to protect their data. Nearly all wireless network technology comes with some basic security features that need only to be activated (激活) in order to give a minimum level of security, for example, by encrypting the data being passed over the network.
Raymon Kruck, business development manager at Check Point Software, a security technology specialist, believes this could be partly a psychological problem. People see the solid walls of their building as safeguards and forget that wireless networks can extend up to 200 meters beyond physical walls.
Companies without any security at all on their wireless networks make it ridiculously easy for hackers to break in. Switching on the security that comes with the network technology should be automatic. Then there are other basic steps a company can take, says Mr. Kruck, such as changing the passwords on the network from the default (默认) setting.
Companies can also install firewalls, which form a barrier between the internal network and the public Internet. They should also check their computer records regularly to spot any abnormal activity, which might betray the presence of a hacker.
According to the study sponsored by RSA Data Security, two thirds of the subjects _______.

A.had most of their company data stolen
B.depended on wireless computer networks
C.were exposed to drive-by hacking
D.were unaware of the risk of wireless hacking

Whichof the following is NOT considered in the study?

A.The number of computer hacking incidents.
B.The number of wireless computer networks identified.
C.The way in which data are sent and received.
D.The way in which data are hacked and stolen.

Most wireless network technology has_________.

A.data encryption program B.password security programs
C.illegal-user detection D.firewall

Raymond Kruck most probably agrees that wireless network security involves ________.

A.wireless signal administration B.changes in user’s awareness
C.users’ psychological health D.stronger physical walls

The passage is most likely to be seen in a __________

A.book review B.science fiction C.textbook D.computer magazine

Cold weather has a great effect on how our minds and our bodies work. Maybe that is why there are so many expressions that use the word “cold”. For centuries, the body’s blood has been linked closely with the emotions. People who show no human emotions or feelings, for example, are said to be cold-blooded. Cold-blooded people act in merciless ways. They may do brutal things to others, and not by accident. For example, a newspaper says the police are searching for a cold-blooded killer. The killer murdered someone, not in self-defense. He seemed to kill for no reason, and with no emotion, as if taking someone’s life meant nothing.
Cold can affect other parts of the body, the feet, for example. Heavy socks can you’re your feet, if your feet are really cold. But there is an expression—to get cold feet—that has nothing to do with cold or your feet.
The expression means being afraid to do something you have decided to do. For example, you agree to be president of an organization. But then you learn that all the other officers have resigned. All the work of the organization will be your responsibility. You are likely to get cold feet about being the president when you understand the situation.
Cold can also affect your shoulder. You give someone the cold shoulder when you refuse to speak to them. You treat them in a distant and cold way. The expression probably comes from the physical act of turning your back toward someone, instead of speaking to him face-to-face. You may give a cold shoulder to a friend who has not kept a promise he made to you, or to someone who has lied about you to others.
A cold fish is not a fish. It is a person. But it is a person who is unfriendly, unemotional and shows no love or warmth. A cold fish does not offer much of himself to anyone.
Out in the cold is an expression often heard. It means not getting something that everybody else got. A person might say that everybody but him got a pay raise, and that he was left out in the cold. And it is not a pleasant place to be.
The passage is intended to tell us that ______ .

A.cold weather has a great effect on human bodies
B.many English expressions contain the word “cold”
C.cold is a word closely linked with human emotions
D.the word “cold” has many different meanings in English
