Passage 58 Cloning As we approach the 21st century, it is clearer than ever that science and technology are changing the way we live and work. The breakthroughs in bioengineering science are helping to reveal the mysteries of life, holding out new hope for lifesaving cures to some of our most dreaded diseases. In 1997, the great news shocked the whole world that the British scientists created a lamb, named Dolly from a single cell. Miraculously, the cell had been taken from the udder of an adult sheep, which marks the first time an adult animal had been successfully cloned. But it soon caused worldwide concern over its ethical, social, and scientific implications. Cloning is especially controversial because it raises the prospect of “making humans genetically identical to an existing man or woman. Some people claim attempting to use these cloning techniques to actually clone a human being is untested and unsafe and morally unacceptable. How to look upon this new technique? When it comes to a discovery like cloning, we must move with caution, care and deep concern about the impact of our actions. First, cloning should be greatly esteemed and great thanks should be given to its inventors. Meanwhile, great efforts should be made to place this technique under strict control. Especially we should adopt a document against human cloning since past experience tells us a new invention may cause troubles if it is misused.

阅读理解，阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项。

　　Of course, the main difference on the Chinese dinner table is chopsticks instead of knife and fork, but that's only superficial．Besides, in decent restaurants, you can always ask for a pair of knife and fork, if you find the chopsticks not helpful enough．The real difference is that in the West, you have your own plate of food, while in China the dishes are placed on the table and everyone shares．If you are being treated to a formal dinner and particularly if the host thinks you’re in the country for the first time, he will do the best to give you a taste of many different types of dishes．

　　The meal usually begins with a set of at least four cold dishes, to be followed by the main courses of hot meat and vegetable dishes．Soup then will be served(unless in Guangdong style restaurants)to be followed by staple food ranging from rice, noodles to dumplings．If you wish to have your rice to go with other dishes, you should say so in good time, for most of the Chinese choose to have the staple food at last or have none of them at all．

　　Perhaps one of the things that surprises a Western visitor most is that some of the Chinese hosts like to put food into the plates of their guests．In formal dinners, there are always “public” chopsticks and spoons for this purpose, but some hosts may use their own chopsticks．This is a sign of genuine friendship and politeness．It is always polite to eat the food．If you do not eat it, just leave the food in the plate．

　　People in China tend to over-order food, for they will find it embarrassing if all the food is consumed．When you have had enough, just say so．Or you will always overeat!
