1 . From the beginning of the Internet, online dating (约会) has become one of the most popular things to all the consumers (顾客)．Although this may be fun, it is important to remember to think of your safety when trying to meet that certain somebody.When talking about safety I am referring to taking care of your computer and yourself.

Before getting into the world of online dating you should make sure you take care of protecting your computer.A good fire wall and an anti­virus program are a must. These are needed to protect your emails and anywhere you surf on the Internet.   There are many great programs offered at your local computer store or available to buy online.   With great programs often come some pretty good costs.   There is something that is better for the people who just can't afford the cost of a good anti­virus—you can find quite a few decent ones on the Internet for free.

Protecting yourself could surely be much more important than protecting your computer. You want to be careful in choosing your dating sites. Do some good research. If you know anyone who has tried an online dating   service，ask them what they thought. There are so many online dating sites that you should do extensive (广泛的) researches. Make sure you keep the web addresses. Keep a list of fees, regulations and anything else that looks interesting to you. If a place looks shady or makes you feel uncomfortable then you should steer clear away. At the end of the day make sure you take care of yourself.

2 . You can never be too sure these days in the United States of your neighbors or even your customers! Try to keep a low profile (姿态) in your neighborhood: Don’t announce to everyone that you are running a home business with thousands of dollars worth of equipment. As much as possible, do not invite clients (客户) or visitors to your home. In fact, I know of some home­based entrepreneurs (企业家) who would rather meet their clients in a neutral ground, e.g. the client’s office or even Starbucks.
There are other ways to keep burglars away from your house.
•Keep lights on around your house in the evenings. Light is a natural fright for burglars.
•Invest in a security alarm, particularly if your house is located at a remote spot. Security systems can often bring down the cost of your homeowner’s premium (保险费).
•Make sure that all windows and doors are locked and the security alarm turned on before you sleep at night or go out of the house. Avoid keeping house keys in obvious places, such as under the lamp or on top of the doorframe.
•Adding an additional lock will provide extra security when you are home. The dead­lock, sometimes called an “exit only deadbolt”is a deadbolt that does not have an external (外部的) key. It is clearly visible on the door from the outside, but cannot be broken into without destroying the door, frame or lock itself. While this security won’t help directly when you aren’t home, the visibility may discourage an____ from trying the door.
•Your door itself should be made of strong materials, such as one­inch thick solid hardwood or heavy metal.

3 . Many people turn to doctors or self-help books, but they forget a great thing that could help them fight illness: their friends.
Researchers are only now starting to pay attention to the importance of friendship in health. A 10-year Australian study found that older people with a large circle of friends were 22 percent less likely to die during the study period than those with fewer friends. A large 2007 study showed an increase of nearly 60 percent in the danger for obesity among people whose friends gained weight. And last year, Harvard researchers reported that strong social ties(关系) could improve brain health as we age.
“In general, the role of friendship in our lives isn’t well realized,” said Rebecca, a professor at the University of North Carolina. “Friendship has a bigger effect on our psychological (心理的) health than family relationships.”
While many friendship studies are about the close relationships of women, some research shows that it can do good to men too. In a six-year study of 736 middle-aged men, having friendships reduces the risk of heart attack. Only smoking was as important a danger factor (因素) as having little social support.
The exact reason why friendship has such a big effect isn’t clear. While friends can send a sick person to the hospital or pick up medicine, the advantages go well beyond physical help. Friendship clearly has a big psychological effect. “People with stronger friendships feel like there is someone they can turn to,” said Karen, a doctor. “The message of these studies is that friends make your life better.”

4. Which of the following has the closest meaning to the underlined word “obesity”?

A．fatness	B．unhappiness
C．excitement	D．health

4 . I travel a lot, and I find out different “styles”(风格)of directions every time I ask “ How can I get to the post office?”
Foreign tourists are often confused(困惑的)in Japan because most streets there don’t have names. In Japan, people use landmarks(地标)in their directions instead of street names. For example, the Japanese will say to travelers, “ Go straight down to the corner. Turn left at the big hotel and go past a fruit market. The post office is across from the bus stop.”
In the countryside of the American Midwest, there are not usually many landmarks. There are no mountains, so the land is very flat. In many places there are no towns or buildings within miles. Instead of landmarks, people will tell you directions and distances. In Kansas or Iowa, for example, people will say, “ Go north two miles. Turn east, and then go another mile.
People in Los Angeles, California, have no idea of distance on the map. They measure distance in time, not miles. “ How far away is the post office?” you ask. “ Oh,” they answer, “ it’s about five minutes from here.” You say, “ Yes, but how many miles is it?” They don’t know.
It’s true that a person doesn't know the answer to your question sometimes. What happens in such a situation? A New Yorker might say, “ Sorry, I have no idea.” But in Yucatan, Mexico, no one answers “ I don't know”. People in Yucatan believe that “I don't know” is impolite. They usually give an answer, often a wrong one. A tourist can get very, very lost in Yucatan!
