There is virtue in working standing up. It sounds like a fashion. But it does have a basis in science.
That, by itself, may not be surprising. Health ministries ask people for decades to do more exercise. What is surprising is that long periods of inactivity are bad regardless of how much time you also spend on officially approved high-impact stuff like pounding treadmills(跑步机) in the gym. What you need instead, the latest research suggests, is constant low-level activity. This can be so low-level that you might not think of it as activity at all. Even just standing up counts, for it invokes muscles that sitting does not.
Researchers in this field trace the history of the idea that standing up is good for you back to 1953, when a study published in The Lancet found that bus conductors, who spent their days standing, had a risk of heart attack half that of bus drivers, who spent their shifts on their backsides. But as the health benefits of exercise and vigorous(强度大的) physical activity began to become clear in the 1970s, says David Dunstan, a researcher at the Baker IDI Heart & Diabetes Institute in Melbourne, Australia, interest in low-intensity activity --- like walking and standing --- became weaker.
Over the past few years, however, interest has been excited again. A series of studies, none big enough to provide convincing evidence, but all pointing in the same direction, persuaded Emma Wilmot of the University of Leicester, in Britain, to carry out a meta-analysis. This is a technique that combines diverse studies in a statistically meaningful way. Dr Wilmot combined 18 of them, covering almost 800,000 people and concluded that those individuals who are the least active in their normal daily lives are twice as likely to develop diabetes(糖尿病) as those who are the most active. She also found that the immobile are twice as likely to die from a heart attack and two-and-a-half times as likely to suffer cardiovascular disease as the most mobile. Crucially, all this seemed to be independent of the amount of vigorous, gym-style exercise that volunteers did.
1.The surprising thing mentioned in Paragraph 2 is that ______.
A. Low-level activities are better than high-level ones.
B. Long periods of inactivity are bad to people’s health
C. The benefits of high-impact exercise are not highly approved by people
D. Strong physical activities cannot make up for the bad effects of inactivity.
2.Why did people lose interest in low-intensity activity in the 1970s?
A. Researchers didn’t devote much to studying their health benefits.
B. The health benefits of high-impact exercise were widely recognized.
C. It was believed to be unable to invoke all the muscles of the body.
D. It was proved not so effective in reducing the risk of heart attacks.
3.The findings made by Dr Wilmot ______.
A. disagreed with her assumption
B. consisted with the results of the 1953 study
C. changed her original research objectives
D. confirmed David Dunstan’s research results
4.What’s the passage mainly about?
A. The history of the theory.
B. The benefits of standing up.
C. Low-level activity and health.
D. A series of epidemiological studies.

It took courage to stand up at work. Now more and more people like to have a change and stand up when they are on something important. Standing up is popular. Medical researchers have found that people who stand at work tend to be much healthier than those who sit.
In the last few years, many office supply companies have begun to sell the adjustable- height desk. These so- called “ sit/ stand” models are equipped with an electric motor that lets them shift from chair height to person height at the push of a button. Unfortunately, they’re regarded as specially furniture. Sit/ stand desks tend to be expensive, hard to find and not easy to test it in person.
When you worked standing up, your mind was more excited and new ideas kept coming out. This is because when you’re standing, you feel a bit unchained from your desk. If you got stuck on a word or sentence as you wrote, you found yourself shaking your arms, bouncing on your feet or stepping away from the desk for a bit------ things you couldn’t do in a chair. Often, standing up seemed to relax your mind enough for you to get over creative barriers.
There’s one other thing about standing for a long time; you tended to get hungrier than you do when you sit on a chair. That felt like confirmation of the stand-up advocates’ belief that you burn more calories when you stand than when you sit. For this reason alone, I’m hoping that sit/ stand desks one day hit the mainstream, with mass- market furniture companies making many low- priced versions. We could all do with a bit more standing up.
1.We can learn that the adjustable- height desk is_______.
| A．easy to find | B．easy to test |
| C．relatively cheap | D．smart in operation |
2.According to para.3, standing up while working ______.
| A．tends to make us much healthier |
| B．get us distracted from the work at hand |
| C．can make us relaxed and be creative |
| D．make us move about and unfocused |
3.The underlined word “ unchained” in para.3 means “_______”
| A．free | B．tired | C．uneasy | D．Unbalanced |

It's been said that honesty is the best policy．It sounds like the simplest thing in the world，but being truly honest with others and with yourself can be a real challenge．Most of us learned to be dishonest as children．Remember that dishonesty is rooted in fear，so you must look for and face those fears．By listing areas where you have a problem，and then working to deal with them，you can battle these habits．If you find yourself lying because you fear disapproval from someone，for example，perhaps you need to learn how to stop being a people pleaser and be yourself．Most importantly，admit your errors so that you can forgive yourself and use those experiences to reinforce your determination to do better．
If you feel guilty for having been dishonest in the past，apologize to the person you lied to or find a creative way to make things right．If you've lied to a person who plays an important role in your life （a significant other，relative，or friend），the best （but most difficult） thing to do is to come clean．
Think honestly．This may sound silly，but if you don't think honestly，you won't be honest．
If you're pushed into a corner and don't know how to respond，you have the right to remain silent or say"Can we talk about this another time?"or"I really don't feel comfortable talking about this．"Don't say"I don't know．"
Practice being honest on the simple things．Abraham Lincoln became famous for going to great lengths to return a few cents that did not belong to him，hence the nickname"Honest Abe"．By applying honesty to the little things，you will get in the habit of being honest in general．

Even if he is not the most liked comedian in China today, his popularity certainly has risen the fastest within the last two months.
He's "Little Shenyang", who came into national fame overnight after his appearance on CCTV's Spring Festival Gala. With his funny cross-dressing, unique northeastern accent and superb imitative(模仿的) skills, Little Shenyang has obvious talent to support his rise to fame.
Hundreds of video clips of his shows have been posted on YouTube and other online video sites, and his performance fees reportedly grew 50-fold in just a few weeks. He has, at the same time, become one of the most controversial of entertainers.
Many have doubted his artistic potential, pointing out that his shows were repetitive and lacked creativity, a key to continued comedic success. Others belittle (轻视) the style of humor, saying it's too crude and appeals only to less-educated people. His defenders were just as up in arms. Many media commentators and bloggers said that his quick rise to star proved the broad appeal of his art form. He became a national champion not because of his "northeastern hick(乡巴佬)" humor, they argued, but because he represented something new on TV, something with a grassroots feel that appealed to millions of ordinary people.
Now, does Little Shenyang really deserve his star status?
1. Some people belittle Little Shenyang’s humor because _________.
A. He represents something with a grassroots feel.
B. The style of humor lacked creativity.
C. He speaks with a northeast accent.
D. He became famous overnight.
2.What’s the secret of Little Shenyang’s success?
A. His funny cross-dressing.
B. His unique accent
C. His super imitative skills
D. All of the above
3.From the passage, we can infer that _________.
A. Little Shenyang is the most popular comedian in China.
B. Few people like Little Shenyang’s performance.
C. Little Shenyang earns a lot of money now.
D. The author thinks little of Little Shenyang.

It is 43 that you do not agree with the belief of your elders, but this is nothing new. All younger generations have always 44 with their elders and it is these differences that bring changes in human 45. However much you disagree with them, give them credit for their 46.
With changing times and 47 influences, youngsters no longer know what is interpreted as disrespect to elders. Youngsters should 48 express their views and if there are arguments, they should not 49 their voices.
If there is no space on sofas or chairs, children will immediately 50 their places, and sit on the carpet. In buses and trains, youngsters are 51 to give up their places to older people. This is not a 52 of who has more rights.
