If your job requires a lot of sitting, you could be putting your health at danger.

The American Journal of Epidemiology (流行病學(xué)) did a study in 2010 on the correlation (相互聯(lián)系) between sitting and an individual's physical health. In the study, 53,440 working men and 69,776 working women were surveyed on their time spent sitting. The subjects were all disease free when employed. The researchers identified 11,307 deaths in men and 7,923 deaths in women during the 14-year follow-up.

The findings: Women who reported sitting for more than six hours per day had an approximately 40 higher all-cause death rate than those who reported less than three hours a day, and men had an approximately 20 higher death rate.

Well, now's a fine time to get this information. But why didn't they tell me this years ago? I would have planned on taking a more active job instead of the sedentary (坐著的) job of an editor.

So what can you do if you have to work for a living at a job that requires a lot of sitting? Here are some ideas:

Take frequent breaks. It is recommended that workers vary activities, change their position, and take short breaks every 20 minutes to rest muscles and increase blood circulation. Get a standing desk. Some studies have shown that working from an upright position may be better for health. The serious fitness people can even purchase a treadmill (跑步機(jī)) desk. It only goes about one mile per hour. Have a walking meeting. If your group is kind of small, going for a walk while discussing topics is a good alternative.

A. found men reporting shorter sitting time than women

B. surveyed more men than women on their daily sitting time

D. discovered correlation between sitting and physical health in men and in women

2.We can infer from the text that the author did not recommend ______.

C. quitting sedentary jobs D. taking a walk while discussing

3.What does the underlined word "subjects" in Paragraph 2 mean?

My friend had mentioned the other day that her father had a lot of children's toys he was looking to give away. She knew I have a three-year-old daughter so she thought of me first. I told her I would love it if I could get some nice things for my daughter, which I wouldn't otherwise have been able to afford.

When I met her father, he began to explain he was too poor once and that he would hate to throw away things that can be very useful.

Before he showed me what he was giving away, I thought the toys would be mostly lego's(樂(lè)高積木) or things like that. When he was showing me around I saw a bed, a slide, a kitchen set and many other things that just blew my mind. He told me to write a list of everything my daughter could use and as my eyes were wide, he told me not to feel guilty. He said I was helping him by getting rid of the stuff.

As I was looking around I did feel guilty, but I tried to remain more grateful than guilty. Every time I tried to thank him for giving me and my daughter all this wonderful stuff he would thank me right back. I wanted to believe that he was just thanking me so that I wouldn't feel so guilty but in reality I believe that he was as grateful as I was that these toys would be put to good use.

In the eyes of charity, it makes sense to feel grateful, but guilt is just as normal. I know that we could have lived without a slide, which is why I do feel guilty, but I am grateful all the same because my daughter really does enjoy all these nice things!

1.Why did the old man want to give away his toys?

A.He wanted to help those poor children.

B.He was wealthy enough to buy new toys.

C.He wanted to make full use of those toys.

D.He needed some space for more useful things.

2.In the writer's opinion, the old man felt grateful because________.

A.he wanted to make her more guilty

B.he wanted her to take the toys quickly

C.the toys would be put to good use

D.he finally got rid of the stuff

3.What can we know from the passage?

A.The writer took all the toys home.

B.The old man was a kind and thoughtful person

C.The writer wanted to refuse the stuff when she first saw them.

D.The writer's daughter enjoyed the slide most among all the stuff.

4.How did the writer feel when given the stuff?

A.Guilty and honored. B.Grateful and respected.

C.Honored and respected. D.Guilty and grateful.

People become quite illogical when they try to decide what can be eaten and what cannot be eaten. If you lived in the Mediterranean, for instance, you would consider octopus (章魚(yú)) a great delicacy. You would not be able to understand why some people find it repulsive. On the other hand, your stomach would turn at the idea of frying potatoes in animal fat --the normally accepted practice in many northern countries. The sad truth is that most of us have been brought up to eat certain foods and we stick to them all our lives.

No creature has received more praise and abuse than the common garden snail(蝸牛). Cooked in wine, snails are a great luxury in various parts of the world. There are countless people who, ever since their early years, have learned to associate snails with food. My friend, Robert, lives in a country where snails are not liked. As his flat is in a large town, he has no garden of his own. For years he has been asking me to collect snails from my garden and take them to him.

The idea never appealed to me very much, but one day, after heavy shower, I happened to be walking in my garden when I noticed a huge number of snails taking a stroll on some of my prized plants. Acting on a sudden impulse, I collected several dozen, put them in a paperbag,and took them to Robert. Robert was delighted to see me and equally pleased with my little gift. I left the bag in the hall and Robert and I went into the living room where we talked for a couple of hours. 1 had forgotten all about the snails when Robert suddenly said that I must stay to dinner. Snails would, of course, be the main dish. I did not fancy the idea and I reluctantly followed Robert out of the room. To our dismay, we saw that there were snails everywhere: they had escaped from the paper bag and had taken complete possession of the hall! I have never been able to look at a snail since then.

1. The underlined word “repulsive” in Paragraph 1 most probably means .

A.disgusting B. pleasant

C. acceptable D. delicious

2. We can infer from Paragraph 3 that when collecting the snails, the author .

A.was glad that he could share them with his friend.

B.was angry because they might damage his beloved plants.

C.was excited about being able to give his friend a surprise.

D.was depressed because it was hard to catch them all.

3. The author finds that snails .

A. are as delicious as octopus.

B. are disliked in his hometown.

C.are the most controversial food.

D. are as popular as fried potatoes.

4.The best title for the passage might be “ ”

A. One Man’s Meat is Another Man’s Poison

B. Foods and Cultures

C. Snail and Octopus

D. People Are Illogical in Front of Delicacies
