每课必练系列答案It was my birthday last Thursday. I decided to 36 by inviting a few friends out to supper. I chose a restaurant in a 37 part of town. It is one of my favorite restaurants because the food is good and the waiters are friendly. It is 38 ever crowded, because not many people know about it, so it is not usually 39 to book(预定) a table. In any case, Thursday is not a busy evening 40 .
When we entered the restaurant, we were surprised to find it completely 41 . I looked around but no 42 was free. One of the waiters recognized me. He came across and explained the situation. “A party of tourists(旅游团) came in about half an hour ago,” he said. “It was like an invasion (侵略). 43 the place was full! We can hardly manage (对付，应付).”
The waiter then pointed to a table in the corner. “The people there are about to 44 ,” he said. “Just hold on and you’ll 45 a place there.” He was right. Fifteen minutes later, the people 46 the corner table paid their 47 , got up and left. I led my friends across and we all sat down.
48 , our table was almost out of sight. We tried to call the attention of the waiter who sent us there, 49 he, like all the other waiters, was 50 with the party of tourists. They ordered lots of food. At last, an hour later, the tourists were finishing their meal and looking very 51 with life. The waiter, now very tired, appeared at our table. I advised my friends about the best dishes and finally the waiter went off with our 52 .
A few moments later he returned to our table. We could tell from his face that he had 53 news for us. 54 a little sorry he told us that there was no meat or fish. “All we can 55 you,” he said, “is an omelet (煎蛋卷) !”

Mark Ramirez, a senior executive at AOL, could work in the comfortable leather chair, if he wanted. No, thanks. He prefers to stand most of the day at a desk raised above stomach level.
“I’ve got my knees bent. I feel totally alive,” he said. “It feels more natural to stand.”
In the past few years, standing has become the new sitting for 10 percent of AOL employees at the firm’s Virginia branch. Part of a standing popularity is among accountants, programmers, telemarketers and other office workers across the nation.
GeekDesk, a California firm that sells desks raised by electric motors, says sales will triple this year.
Standers give various reasons for taking to their feet: It makes them feel more focused, prevents drowsiness(困倦睡意), and makes them feel like a general even if they just push paper. (Former Defense Secretary Donald Rumsfels works standing up. So does novelist Philip Roth.)
But unknown to them, a debate (辩论) is spreading among ergonomics experts（人类工程学家） and public-health researchers about whether all office workers should be encouraged to stand—to save lives.
Doctors point to surprising new research showing higher rates of diabetes, obesity, heart disease and even mortality among people who sit for long stretches. A study earlier this year in the American Journal of Epidemiology showed that among 123,000 adults followed over 14 years, those who sat more than six hours a day were at least 18 percent more likely to die during the time period studied than those who sat less than three hours a day.
“Every rock we turn over when it comes to sitting is astonishing,” said Marc Hamilton, a leading researcher on inactivity physiology at the Pennington Biomedical Research Center in Louisiana. “Sitting is harmful. It’s dangerous. We are on the cusp (尖端) of a major revolution.” He calls sitting “the new smoking”.
Not so fast, other experts say. Standing too much at work will cause more long-term back injuries. Incidences of varicose veins(静脉曲张) among women will increase. The heart will have to pump more.
Hedge, the Cornell professor, isn’t a fan of all this standing. “Making people stand all day is dumb,” he said.
The sensible and most cost-effective strategy（策略）, he said, is to sit in a neutral posture（姿势）, slightly reclined(下弯的), with the keyboard on a tray above the lap. This position promotes positive blood flow. Workers should occasionally walk around, stretch and avoid prolonged periods at the desk. The key, he said, is movement, not standing.
