During the meal, you’d better be careful not to leave a spoon in a soup bowl or coffee cup or any other dish. The coffee spoon ought to be on the saucer, the soup spoon ought to be on the plate under the bowl. When you are having soup, make the least noises and use the side of your spoon inside out this way, not the tip. And you mustn’t pick up your soup bowls so as to drink away the last drops of your soup from the bottom of the bowl.
Very often there is only one main course and salad, followed by your sweet. If you find the meal not enough, say "Oh, it’s delicious!" and ask for some more of the chicken or steak or whatever you have just had. The hostess will be very glad that you appreciate her cooking and will give you an extra portion. But if you observe the Chinese way of being polite and say "No, thank you" when the hostess offers you more, you will most probably starve later. Because Americans will never press food on you. Yet it is not polite to keep silent and not to talk with the person next to you. It would be considered good manners if you handle your silverware(餐具) with care so that they don’t make any noise. When coffee comes, drink it from your cup. The coffee spoon should rest on the saucer while you are drinking. And smoking, of course, is rarely seen at a dinner table. Well, when the meal is finished, the guests put their napkins(餐巾) on the table and stand up, the men again helping the ladies with their chairs.
After the dinner, the guests usually stay for an hour or two, then they would say, "Well, I’m afraid I must be going now. The host and hostess would of course urge everyone to stay longer. "What, already Won’t you have another coffee" The guests, for instance, would say, "I’d love to, but I have to be up early tomorrow. Thank you for a most enjoyable evening. Good—night.
And if you stay overnight or over the weekend, it will be courteous to send a thank-you note to the host or hostess the following day, very often with a small gift’ such as a box of chocolate or some flowers as a token of appreciation of the passage.

第一篇 Eye-tracker Lots You Drag and Drop Files with a Glance Bored of using a mouse? Soon you’ll be able to change stuff on your computer screen – and then move it directly onto your smartphone or tablet(平板电脑) –with nothing more than a glance. A system called EyeDrop uses a head-mounted eye tracker that simultaneously records your field of view so it knows where you are looking on the screen. Gazing at an object – a photo, say – and then pressing a key, selects that object. It can then be moved from the screen to a tablet or smartphone just by glancing at the second device, as long as the two are connected wirelessly. "The beauty of using gaze to support this is that our eyes naturally focus on content that we want to acquire, "says Jayson Turner, who developed the system with colleagues at Lancaster University, UK. Turner believes EyeDrop would be useful to transfer an interactive map or contact information from a public display to your smartphone or for sharing photos. A button needs to be used to select the object you are looking at otherwise you end up with the "Midas touch"(点石成金) effect, whereby everything you look at gets selected by your gaze, says Turner. "Imagine if your mouse clicked on everything it pointed at," he says. Christian Holz, a researcher in human-computer interaction at Yahoo Labs in Sunnyvale, California, says the system is a nice take on getting round this fundamental problem of using gaze-tracking to interact. "EyeDrop solves this in a slick (灵巧的)way by combining it with input on the touch devices we carry with us most of the time anyway and using touch input as a clutching mechanism," he says. "This now allows users to seamlessly(无缝地) interact across devices far and close in a very natural manner." While current eye-trackers are rather bulky, mainstream consumer devices are not too far away. Swedish firm Tobii is developing gaze-tracking technology that can be installed in laptops and tablets and is expected to be available to buy next year. And the Google Glass headset is expected to include eye-tracking in the future. Turner says he has also looked at how content can be cut and pasted or drag-and-dropped using a mix of gaze and taps on a touch screen. The system was presented at the Conference on Mobile and Ubiquitous Multimedia in Sweden, last week. What is Turner likely to study next?
A:How to drag and drop with gaze and taps. B:How to present the system in public. C:How to get touch screen involved. D:How to cut and paste content from a public display.

Malnutrition (营养不良) ? ?A new World Bank report warns that children who don’t get enough good food in the first two years of life suffer lasting damage. They may be underdeveloped or underweight. They may suffer from poor health or limited intelligence. In addition, poorly nourished children are more likely to drop out of school and earn less money as adults. ? ?The report notes that too little food is not the only cause of poor nutrition. Many children who live in homes with plenty of foods utter for other reasons. For example, the study says that mothers often fail to give their newly born babies their first breast milk. This milk-like substance is called colostrum. It is full of nutrients that improve a baby’s ability to fight infections and disease. ? ?The study also links malnutrition to economic growth in poor countries. A lack of nutrition in early children can cost developing nations up to three percent of their yearly earnings. Many of these same countries have economies that are growing at a rate of two or three percent yearly. The study suggests that poor countries could possibly double their economic growth if they improved nutrition. ? ?Africa and South Asia are affected the most by poor nutrition. The study says about half of all children in India do not get enough good food. The World Bank study also notes that rates of malnutrition in South Asia are almost double those in central and southern Africa. Other parts of world are also severely affected, including Indonesia, Uzbekistan, Yemen, Guatemala and Peru. ? ?The study recommends that developing countries change their policies to deal with malnutrition. Instead of directly providing food, the study suggests educational programs in health care. ? ?World Bank nutrition specialist Meera Shekar said the period of life between pregnancy and two years was extremely important. Governments with limited resources should take direct action to improve nutrition for children during this period. |
A:They may not get enough good nutrition in the first two years. B:They may be underdeveloped or underweight. C:They may feel painful from poor health or limited intelligence. D:They mybe more likely to drop out of school or earn less money as adults.
