In America, when people say “man’s best friend”, they don’t mean another person. Instead, they are talking about a lovely animal:A dog! These words show the friendship between people and animals. Dogs and other pets can give happiness to people’s lives. Some people think of their pets as their children. A few even leave all their money to their pets when they die!
Animals can help people, too. Dogs can be taught to become the “eyes”for a blind person or “ears”for a deaf people. Scientists have found that pets help people live longer! They make people happier, too. Because of that, animals are brought into hospitals for “visit”.
Americans hold “Be---Kind-to-Animals Week”in the first week of May.
Pets shows are held during the week. Even if you don’t live in America, you, too, can do this. How? First, think about how animals make your life richer. If you have a pet, take more time this week to play with it. Remember to give it delicious food. Also, be sure to keep your pet from those unwanted babies.
If you don’t have a pet, be kind to animals around you. For example, if you see a street dog, don’t kick(踢)it or throw things at it. Instead, just leave it alone, or beter yet, make friends with it. If others around you do bad things to an animal, try to shop them. As people, we must protect animals who can’t speak for themselves.

That cold January night, I was growing sick of my life in San Francisco. There I was, walking home at one in the morning after a tiring practice at the theatre. With opening night only a week ago, I was still learning my lines. I was having trouble dealing with my part-time job at the bank and my acting at night at the same time. As I walked, I thought seriously about giving up both acting and San Francisco. City life had become too much for me.
As I walked down empty streets under tall buildings, I felt very small and cold. I began running, both to keep warm and to keep away from any possible robbers (抢劫犯). Very few people were still out except a few sad-looking homeless people under blankets.
About a block from my apartment (公寓房间), I heard a sound behind me. I turned quickly, half expecting to see someone with a knife or a gun. The street was empty. All I saw was a shining streetlight. Still, the noise had made me nervous, so I started to run faster. Not until I reached my apartment building and unlocked the door did I realize what the noise had been. It had been my wallet falling to the sidewalk.
Suddenly I wasn’t cold or tired anymore. I ran out of the door and back to where I’d heard the noise. Although I searched the sidewalk anxiously for fifteen minutes, my wallet was nowhere to be found.
Just as I was about to give up the search, I heard the garbage truck (垃圾车) pull up to the sidewalk next to me. When a voice called from the inside, “ Alisa Camacho?” I thought I was dreaming. How could this man know my name? the door opened, and out jumped a small red-haired man with an amused look in his eye. “Is this what you’re looking for?” he asked, holding up a small square shape.
It was nearly 3 A.M. by the time I got into bed. I wouldn’t get much sleep that night, but I had gotten my wallet back. I also had gotten back some enjoyment of city life. I realized that the city couldn’t be a bad place as long as people were wiling to help each other.

Research by sociologists Scott Coltrance Michele Adams looked at national survey data and found that when men increase their share of housework and childcare, their children are happier, healthier and do better at school.What’s more, when school-aged children do housework with their fathers, they get along better with their peers and have more friends.And they show more positive behaviors than if they do the same work with their mothers.“Because fewer men do housework than women,” said Adams, “when they share the work,it has more influence on children.” Fathers model “co-operative family partnerships”.
When men share housework and childcare, it turns out, their partners are happier.Wives of egalitarian(主张人人平等的)husbands, regardless of class, report the highest levels of marital(婚姻的)satisfaction and lowest rates of depression,and are less likely to see therapists(治疗专家).They are also more likely to stay fit, since they probably have more time on their hands.
And the benefits for men are even greater.Men who share housework and childcare are healthier--physically and psychologically.They smoke less, drink less, and take recreational drugs less often.They are more likely to stay in shape and more likely to go to doctors for routine screenings, but less likely to use emergency rooms or miss work due to illness.
In both Europe and the United States,Dad is becoming the “fun parent”.He takes the kids to the park and plays soccer with the kids; she stays home.“What a great time we had with Dad!” the kids announce as they burst through the kitchen door to a lunch mum prepared.

If your boss asks you to work in Moscow this year, he’d better offer you more money to do so — or even double that depending on where you live now.That’s because Moscow has just been found to be the world’s most expensive city for the second year in a row by Mercer Human Resources Consulting.
Using the cost of living in New York as a base, Mercer determined Moscow is 34.4 percent more expensive including the cost of housing, transportation, food, clothing, household goods and entertainment.
A two-bedroom flat in Moscow now costs $4,000 a month; a CD $24.83, and an international newspaper $6.30, according to Mercer.By comparison, a fast food meal with a hamburger (汉堡包) is a steal at $4.80.
London takes the No.2 place, up from No.5 a year ago, thanks to higher cost of housing and a stronger British pound relative to the dollar.Mercer estimates (估算) London is 26 percent more expensive than New York these days.Following London closely are Seoul and Tokyo, both of which are 22 percent more expensive than New York, while No.5 Hong Kong is 19 percent more costly.
Among North American cities, New York and Los Angeles are the most expensive and are the only two listed in the top 50 of the world’s most expensive cities.But both have fallen since last year’s study — New York came in 15th, down from 10th place, while Los Angeles fell to 42nd from 29th place a year ago.San Francisco came in a distant third at No.54, down 20 places from a year earlier.
Toronto, meanwhile, is Canada’s most expensive city but fell 35 places to take 82nd place worldwide.In Australia, Sydney is the priciest place to live in and No.21 worldwide.
What do the underlined words “a steal” in Paragraph 3 mean?

A.an act of stealing B.something delicious
C.something very cheap D.an act of buying

Vending machines (投币式自动售货机) are found in 16% of U.S.elementary schools, 52% of middle schools and 88% of high schools.About 22% of students in grades 1 through 12 buy food in vending machines each day—and those purchases added an average of 253 calories to their diets, according to a new study in the September issue of the Journal of School Health.
Just to be clear, those were not 253 calories' worth of tofu, yogurt or carrot.The most popular vending machine items included soft drinks, candy, chips, crackers, cookies, cakes and ice cream.On the plus side (好的方面), kids also bought low-fat milk, fruit juice and even fruit, the study found.
But the eventual effect on kids' diets was not good.Those who bought from vending machines ate an average of 156 grams of sugar per day, compared with 146 grams for those who abstained (节制).They also consumed less fiber, iron and vitamin B.
One silver lining: Vending machine customers ate 4% less sodium (钠) than other students--an average of 3,287 milligrams per day compared with 3,436 mg for those who didn't buy from vending machines.That's probably because the extra snacks made kids too full to eat as much at mealtimes, when dishes are especially Salty.In any event, kids should eat no more than 1,200 to 1,500 mg of sodium each day, according to the Mayo Clinic.Even for adults, the government recommends a daily limit of 2,300 mg.
Overall, vending machines in school appear to be a threat to children's health.The researchers calculated that all that snacking adds up to about14 extra pounds per child per school year.For some students this might be a serious contributor to weight issues.The study was based on data collected from 2,309 children nationwide for the third School Nutrition Dietary Assessment Study, which was
conducted by the U.S.Department of Agriculture's Food and Nutrition Service.
The students using vending machines take in less of all the following EXCEPT .

A.sugar B.fiber C.vitamin D.iron

C.an urgent warning from health experts
D.an increasing concern from the public

B.They have formed healthy eating habits.
C.They eat less food at mealtimes.
