【单选题】We learn from this passage that Americans (). A.are good at cheating B.are polite to anybody C.are sympathetic but honest D.have no sympathy for others

A.
"How far is it to the next village" the American asks a man sitting by the side of the road. In some countries, because the man realizes that the traveler is tired and eager to get to his destination (目的地), he will politely say "Just down the road." He thinks this is more encouraging, gentler, and therefore the wanted answer. So the American drives through the night, getting more and more angry, feeling "tricked". He thinks the man deliberately (故意地) cheated him, for obviously he must have known the distance quite well.
B.
Had conditions been reversed (颠倒过来), the American would have felt he was "cheating" the driver if he had said the next town was close when he knew it was really 15 miles further on. Though, he, too, would be sympathetic (同情的) to the weary driver, he would say "You have a good way to go yet; it is at least 15 miles." The driver might be disappointed, but he would know what to expect.
C.
Whether to be accurate (准确的) or polite leads to many misunderstandings between people of different cultures. If you are aware of the situation in advance, it is sometimes easier to recognize the problem.

【单选题】What is the subject discussed in the text(). A.The theory of programmed cell deaths. B.A great scientist-Sir John Sulston. C.The programmed human life. D.Dangerous diseases.

A.
Whatever our differences as human beings are, we all think we’re more like the rest of the animal world than we realize. It is said that we share 40 percent of our genetic (遗传的) structure with the simple worm.
B.
But that fact has helped Sir John Sulston win the 2002 Nobel Prize for Medicine. Sir John is the founder of the Sanger Institute in Cambridge, which was set up in 1992 to get further understanding of the human genuine (染色体组).
C.
To help them do this, they turned to the worm. The nematode (线虫类的) worm is one of the earliest creatures on planet earth. It is less than one millimeter long, completely transparent and spends its entire life digging holes through sand. But it still has lots to say about human life, and what can be done to make it better.
D.
What the worm told Sir John and his colleagues was that each of cells in the human body is programmed like a computer. They grow, develop and die according to a set of instructions that are coded in our genetic make-up.
E.
Many of the diseases that humans suffer from happen when these instructions go wrong or are not obeyed. When the cell refuses to die but carries on growing instead, this leads to cancer. Heart attacks and diseases like AIDS cause more cell deaths than normal, increasing the damage they do to the body. Sir John was the first scientist to prove the existence of programmed cell death.
