For a lot of people, stewardesses are the face of the airline. They have long associated with ideas of beauty, handsome salaries, free to travel and a glamorous lifestyle. They wear fashionable clothes, always look like models and take the advantage of the job to travel to different parts of the world. Furthermore, being a stewardess can also be very tired and difficult. Stewardesses, most of their working hours are spent on the plane, don't get up or go to bed at regular hour. Often they work very long hours comparing to most people. They usually needed to arrive at the airport well before their flight leaves. Although being a stewardess can be difficult, they still take pride and pleasure on their jobs.

Why do people choose organic food?
Organic food is fruits and vegetables that 1. (grow) without adding any agricultural chemicals to them. Many people choose to eat organic food because they believe that such fruits and vegetables contain more nutrition, 2. (be) free of chemicals and taste better.
According to two former 3.(analysis), organic fruits and vegetables are healthier for us 4. they have more nutrition in them. On average, fresh organic fruits and vegetables contain 50 percent more vitamins and minerals than food 5.(treat) with chemicals. All of these things are necessary for our health.
Organic food doesn't contain chemicals. When growing organic crops, farmers do not use sprays to kill pests, 6. do they use chemicals to make the crops grow faster. However, chemicals may be used in 7.(convention) produce to make them appear brighter, taste sweeter or last longer. A small amount of these chemicals may remain on the produce, and then accumulate in our bodies,8.(cause) health problems, such as heart disease and cancer.
Finally, many people argue that since organic food is planted without adding chemicals,9. tastes much better. All this has led many 10. the conclusion that organic fruits and vegetables are the best and healthiest choice for us.
I'd like to suggest that for sixty to ninety minutes each evening all television broadcasting in the United States be forbidden by law. Let us take a _______, reasonable look at what the results might be if such a (n) _______ were accepted.
Families might use the time for a real family hour. Without the distraction (分散注意力) of TV, they might _______ together after dinner and actually talk to one another. It is well known that many of our _______—everything in fact, from the generation gap to the high divorce rate to some forms of _______illness — are caused at least in part by _______ to communicate. By using the quiet family hour to _______ our problems, we might get to know each other better, and to like each other better. On evenings when such talk is _______, families could discover more active pastimes (消遣). Freed from TV and forced to find their own activities, they might take a _______ together to watch the sunset ________ they might take a walk together outdoors.
________ free time and no TV, children and adults might discover reading. There is more entertainment in a (n) ________ than in a TV program. ________ report that the generation growing up with television can hardly write an English sentence, ________ at the college level. ________ is often learned from reading. A more literate new generation could be a product of the quiet hour.
A different ________ of reading might also be done as it was in the past: reading aloud. The quiet hour could become the story hour. When the ________ ends, the TV networks might be forced to ________ with better shows in order to get us back from our newly-discovered activities.
At first glance, this idea seems radical (激进的). How will we spend the time then? The fact is: it has been only twenty-five years ________ television came to control American free time. Those of us thirty-five and older can ________ childhoods without television. It wasn't that difficult.

Whether you are racing or touring, long-distance cycling can be very rewarding. 1. In general, it is more important to prepare your mind and your gear (齿轮) for the challenge ahead than it is to train your body. The best way to physically train for a long cycling trip is to take a long cycling trip! There are several steps for you.
Stretch first! Warm up for at least ten minutes before each long-distance cycling session. 2. This way, you can reduce the risk of injury.
Pace yourself. 3. Try to keep up this pace as best you can. Use a lower gear so that you don't wear yourself out. Try to keep up a rate of roughly 90 rpm(revolutions［旋转］per minute) on a low gear to go easy on your muscles and lungs.
Shift gears. When you come to a hill, change into a lower gear so that you can more easily reach the top. 4. Throughout the ride, stay aware of how hard you are working. If you are struggling to push the pedals (踏板), you should switch into a lower gear to conserve your energy.
5. Even if you feel strong, stop every 10-20 miles to give your body a rest and ensure that everything is running smoothly. Rehydrate (补水) by drinking some water, and boost your energy levels with a quick snack. Keep doing so until you arrive at your destination.
A. Take regular breaks.
B. You are sure to face some challenges during your cycling.
C. You should make better use of gears.
D. Try some exercises like jumping and jogging in place.
E. When going down, you should change to a higher gear.
F. It trains your body and provides a chance to appreciate the beauty along the road.
G. Start cycling at a speed which suits you.
A team of engineers at Harvard University has been inspired by Nature to create the first robotic fly. The mechanical fly has become a platform for a series of new high-tech integrated systems. Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.
“It’s extremely important for us to think about this as a whole system and not just the sum of a bunch of individual components (元件),” said Robert Wood, the Harvard engineering professor who has been working on the robotic fly project for over a decade. A few years ago, his team got the go-ahead to start piecing together the components. “The added difficulty with a project like this is that actually none of those components are off the shelf and so we have to develop them all on our own,” he said.
They engineered a series of systems to start and drive the robotic fly. “The seemingly simple system which just moves the wings has a number of interdependencies on the individual components, each of which individually has to perform well, but then has to be matched well to everything it’s connected to,” said Wood. The flight device was built into a set of power, computation, sensing and control systems. Wood says the success of the project proves that the flying robot with these tiny components can be built and manufactured.
While this first robotic flyer is linked to a small, off-board power source, the goal is eventually to equip it with a built-in power source, so that it might someday perform data-gathering work at rescue sites, in farmers’ fields or on the battlefield. “Basically it should be able to take off, land and fly around,” he said.
Wood says the design offers a new way to study flight mechanics and control at insect-scale. Yet, the power, sensing and computation technologies on board could have much broader applications. “You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animals, but using these robots instead,” he said. “So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day to day basis.”
1.The difficulty the team of engineers met with while making the robotic fly was that __________.
A.they had no model in their mind
B.they did not have sufficient time
C.they had no ready-made components
D.they could not assemble the components
2.It can be inferred from paragraphs 3 and 4 that the robotic fly __________.
A.consists of a flight device and a control system
B.can just fly in limited areas at the present time
C.can collect information from many sources
D.has been put into wide application
3.Which of the following can be learned from the passage?
A.The robotic flyer is designed to learn about insects.
B.Animals are not allowed in biological experiments.
C.There used to be few ways to study how insects fly.
D.Wood’s design can replace animals in some experiments.
4.Which of the following might be the best title of the passage?
A.Father of Robotic Fly
B.Inspiration from Engineering Science
C.Robotic Fly Imitates Real Life Insect
D.Harvard Breaks Through in Insect Study
