Be Careful about Cloning

After a series of initial experiments and corrections, the scientist’s hard work paid off when the

twin clone turkeys were hatched with normal feather and claws. This breakthrough possibly enabled people

to bring their adored pets back to life. However, it bothered him from time to time that their health

was in poor condition because they were unable to resist illnesses. This drawback cast him down. Merely

2 weeks later, the clones and their carrier died, which struck frustration into his heart. He retired

before he attained his ambition and became a member of an opera chorus to relieve his depression.

Shortly afterwards, the media published a conservative argument objecting to cloning owing to moral

problems, and suggested the constitution include compulsory regulations to forbid obtaining commercial

profits from cloning.

When interviewed, the scientist stared at the decorations on the ceiling, thinking for a while, and

then said, “I’m not in favour of any arbitrary assumption, but undertaking cloning does differ from

the straightforward procedure of making loafs out of flour. Until we accumulate enough exact knowledge,

any practice is in vain and is bound to fail. Altogether, being more careful is reasonable or we may

walk into a side road.”

慎重对待克隆

在最初一系列的实验和修正之后，科学家的辛劳工作终于取得了成功，一对双生的克隆火鸡孵化出来，羽毛和爪子都专门正常。这一突破或许能让人们使他们喜爱的宠物死而复生。然而，使他不时地苦恼的是，因为它们无法抗击疾病，使得它们的健康状况极差。那个缺点让他专门沮丧。仅仅过了两个星期，克隆体和母体都死亡了，这使他内内心充满了挫折，他也因此在达到自己目标前就退休了，并选择加入歌剧合唱团来减轻消沉的感受。

之后不久，媒体就因为道德问题而发表了反对克隆的保守论点，同时建议宪法应该包括强制性的法规禁止通过克隆获得商业利益。

当被采访时，科学家盯着天花板上的装饰物摸索了一会儿，说：“我不赞成任何任意的假设，然而从事克隆与用面粉制作面包的简单过程确实不大相同。在我们积存了足够的准确知识前，任何实际操作差不多上白费无功的，注定会失败。总而言之，更加慎重地对待克隆是合理的，否则我们或许会误入歧路。”

话题：3D食物打印 词数：383 难度：★★★★

There's a new frontier in 3D printing that's beginning to e into focus: food.

Recent development has made possible machines that print, cook, and serve foods

on a mass scale. And the industry isn't stopping there.

Food production

With a 3D printer, a cook can print plicated chocolate sculptures and

beautiful pieces for decoration on a wedding cake. Not everybody can do that—it

takes years of experience, but a printer makes it easy. A restaurant in Spain uses a

Foodini to “re­create forms and pieces” of food that are “exactly the same，”

freeing cooks to plete other tasks. In another restaurant, all of the dishes and desserts

it serves are 3D­printed, rather than farm to table.

一、阅读理解。

Sometimes, you just can't help it. Maybe you're watching a sad movie, or thinking about the friend who

moved away. Next thing you know, there's a lump in your throat, your eyes are watering, and you have

tears running down your cheeks.

A professor of psychology at Tilburg University, in the Netherlands,has studied crying.According

to Vingerhoets, there're three types of tears. Basal tears are the first type. They act as a protective

barrier between the eye and the rest of the world.Next are reflex tears. They wash your eyes clean when

something gets in them. Finally, there're emotional tears. “These are released in response to emotional

states,” explains Vingerhoets.

Scientists believe crying has something to do with how humans developed and learned to depend

A

At your next meeting, wait for a pause in conversation and try to measure how

long it lasts.

Among English speakers, chances are that it will be a second or two at most.

But while this pattern may be universal, our awareness of silence differs

dramatically across cultures.

What one culture considers a confusing or awkward pause may be seen by others

as a valuable moment of reflection and a sign of respect for what the last speaker

has said. Research in Dutch (荷兰语) and also in English found that when a silence

in conversation stretches to four seconds, people start to feel uneasy. In contrast,

a separate study of business meetings found that Japanese people are happy with

silences of 8.2 seconds — nearly twice as long as in Americans' meetings.

In Japan, it is recognised that the best communication is when you don't speak
