Everyone knows that fish is good for health. 36 But it seems that many people don't cook fish at home. Americans eat only about fifteen pounds of fish per person per year, but we eat twice as much fish in restaurants as at home. Buying, storing, and cooking fish isn't difficult. 37 This text is about how to buy and cook fish in an easy way. 38 Fresh fish should smell sweet: you should feel that you're standing at the ocean's edge. Any fishy or strong smell means the fish isn't fresh. 39 When you have bought a fish and arrive home, you'd better store the fish in the refrigerator if you don't cook it immediately, but fresh fish should be stored in your fridge for only a day or two. Frozen fish isn't as tasty as the fresh one. There are many common methods used to cook fish. 40 First, clean it and season it with your choice of spices（调料）. Put the whole fish on a plate and steam it in a steam pot for 8 to 10 minutes if it weighs about one pound. （A larger one will take more time.） Then, it's ready to serve.

So there you are on the phone, you ask a question, and suddenly there's silence． What is this, the phone's gone dead, the person you're talking to is dead? Possibly． But there could be another reason — the other person could be Finnish, or Japanese．According to a handy new booklet from British Telecom (BT) for business people, in countries such as Britain and Italy "conversation is a form of entertainment． There is a continuous flow of talk．．．"． But in other countries especially Finland and Japan, "it is not only impolite to break in, but listeners will think over what has been said in silence"．It also points out that English, when spoken by foreigners, is likely to include plenty of "false friends", where word-for-word translation fails． If a Frenchman says something is "interesting", he probably means it's profitable．If he "demands" something, he's actually just asking． If an American says your proposal is "quite good", you should be pleased, because "quite" means "very"． But if he tells you to "table" a proposal, then things are not good at all． Whereas an English person would understand tabling a proposal as putting an idea forward, to an American it means shelves it．According to the booklet, British people are not "explicit" like the Americans, the Dutch, the Germans or the French． "If a Dutchman says an idea is interesting, he means that it is interesting． If an Englishman says it is interesting, you have to deduce (推论) from the way he says it whether he means it is a good or a bad idea．"The Japanese, the Russians and the Arabs on the other hand, live in the land of true dioplomatic subtlety(微妙)．"If they say an idea is interesting, it may simply be out of politeness"．It is safest to stick with plain speaking whenever possible, BT advises its British readers． And whatever you do, be careful to limit the use of the famous British sense of humor．【小题1】When someone says that an idea is interesting, who don't really mean it?A.The Dutch．B.The French．C.The British．D.The Japanese．【小题2】While speaking in English, a foreigner seems .A.to use the words "false friends" quite oftenB.to have a strong foreign accentC.to have difficulty in expressing himself clearlyD.to keep on forgetting English words【小题3】We may learn from the passage that the best thing to do while talking to others, especially to foreigners, is to . A.speak as a diplomatB.be fully aware of culture differenceC.speak with a sense of humorD.avoid being somewhat entertaining

Factories are being digitised, filled with new sensors and new computers to make them quicker, more 2 , and more efficient. Robots are breaking free from the cages that surround them, learning new skills and new ways of working.
