【题目】There once was a master who went to India. In those times, we didn't have the communications or airplanes or many kinds of transportation that we do now. So the master went to India on foot. He had never been to India before; perhaps he came from Persia. And when he got there, he saw a lot of fruit. In India they have plenty of fruit to sell, but much of it is expensive because they can't grow much due to the water situation. So he saw one basket, a big basket of some very red, long fruit. And it was the cheapest in the shop, not expensive at all.

So he went up and asked, "How much per kilo?" And the shopkeeper said, "Two rupees(卢比)." Two rupees in India is nothing; it's like dirt. So he bought a whole kilogram of the fruit and started eating it. But after he ate some of it: Oh, my God! His eyes watered, his mouth watered and burned, his eyes were burning, his head was burning and his face became red. As he coughed and choked and gasped for breath, he jumped up and down, saying, "Ah! Ah! Ah!"But he still continued to eat the fruit! Some people who were looking at him shook their heads and said, "You're crazy, man. Those are chilies(辣椒)! You can't eat so many; they're not good for you! People use them as a condiment(作料), but only a little bit to put into food for taste. You can't just eat them by the handful like that; they're not fruit!" So the stupid master said, "No, I can't stop! I paid money for them, and now I'll eat them. It's my money!"

And you think that master was stupid, right? Similarly, we sometimes do a lot of things like that. We invest money, time or effort in a relationship, business or job. And even though it's been a long time, bitter experience tells us it won't work, and we know there's no more hope that things will change in the future this we definitely know by intuition(直觉) we still continue just because we've invested money, time, effort and love into it. Just like the man who ate the chilies and suffered so much but couldn't stop because he didn't want to waste the money he'd paid.

【1】Why did the master buy a lot of chilies?

A.He loved the taste of chilies very much.

B.He spent a lot of money on chilies.

C.The price of chilies is very low.

D.The quality of Indian chilies is very good.

【2What can we infer about the master according to the passage?

A.He is very wise in spending his money.

B.He came from Persia with someone else.

C.He walked to India for the first time.

D.He is a very rich and honest man.

【3】What is the purpose of the passage?

A.To share us a funny story about a silly master.

B.To tell us when to give up in life.

C.To offer some information about India.

D.To remind us how to spend money wisely.

【题目】C

Penguins can taste only sour and salty food, scientists have discovered. A genetic study suggests the flightless birds lost three of the five basic tastes long ago in evolution.

Taste is critical for survival in most animals, but may not matter in the penguin, which swallows fish whole, say researchers in China and the US.

Many other birds are unable to taste sweet things, but they do have receptors (感受器) for detecting bitter and umami (or meaty) flavours. The discovery was made when researchers decoding penguin genomes found some of the taste genes were missing. A closer look at the DNA of penguins revealed that all species lack functioning genes for the receptors of sweet, umami, and bitter tastes.

“Based on genetic data, penguins are believed to have sour and salty tastes, but have lost sweet, umami, and bitter tastes,” lead researcher Prof Jianzhi Zhang, of the University of Michigan, US, and Wuhan University, China, told the reporter.

The umami taste gives food the strong, savoury (咸味的) flavour associated with meat. Lacking this sense is surprising for a carnivorous (食肉的) animal, but does not matter that much in the penguin, which swallows fish without chewing. “Their behaviour of swallowing food whole, and their tongue structure and function, suggest that penguins need no taste perception,” said Prof Zhang. “Although it is unclear whether these traits (特点) are a cause or a consequence of their major taste loss.” The findings, published in Current Biology journal, were a puzzle, he added.

One clue comes from the bird’s evolution on the frozen ice sheets of Antarctica. Sending signals from sweet, umami, and bitter (but not sour or salty) taste receptors to the brain does not work at very low temperatures. This may have led to the penguin gradually losing its sense of taste, say the researchers.

Intriguingly(有趣的是), the sweet taste is missing in almost all birds. The hummingbird, which feeds on sweet nectar, is an exception.
