Cyclist Alain Such has been dropped from the Ingotel cycling team for two years after a positive drug test at the Institute of drug Free Sport. “ I was flabbergasted.” Said Didier Garcia, from Team Ingotel. “Alain joined our team last month and we had no idea that he was being examined.”

It’s a story that has become more and more familiar in recent years. Dr. Mohammad Farnood, a leading sports scientist from Cairo, Egypt, said, “ It is thought that some athletes will look for other ways to improve performance in addition to using drugs.”

However, it has not always been against the law. In the Olympics in 1904, Thomas Hicks won the marathon after using drugs in the middle of the race. In fact, the first one didn’t make him feel better for long, so he was given another and, as a result, he fell down soon after finishing and knew nothing. Another one may well have killed him.

Things are very different today. Some scientists are considering the possibilities of using genetic engineering to further develop athletes’ abilities. “If it works with no risk of discovering,” said Dr Farnood, “ then it’s likely to become common practice for athletes.”

Researchers are looking at the possibility of identifying “athletic” genes and correcting weak ones. Put into practice, this would make a person healthier and stronger. Once scientists understand what genes of top athletes look like , it might even become possible to identify “athletic” genes in young people, and then money could be spent on children who have the most promising genes.

“People are beginning to recognize that genetics can in many ways do good to our society, for example in saving lives and in creating better quality food for people.” Dr Farnood says. “ So, is it fair to use genetic engineering in sport? You could ask if it’s fair for some runners to use the latest scientifically developed footwear. The key question is whether it’s available to everyone.”

1.What does the underlined word “ flabbergasted” in Paragraph 1 mean ?

A. Shy . B. Proud.

C. Excited. D. Surprised.

2.What happened to Thomas Hicks in 1904 ?

A. He was badly hurt in training.

D. He lost the match in the Olympic Games.

4.What can we learn from Paragraph 5 and 6 ?

Last year, during the summer holiday, I found part-time job, worked in a toothbrush factory at night. Not until I experienced it did I realized that it was no easy job.I went to work when my parents were going to bed. On the morning, when my parents were going to work, I came to home to sleep. This backward schedule was very tough for me that I often felt tiring. But I am glad that I had this unforgettable experience. Not only is it fun to “rise and shine” along with the moon or stars, but also I had learned to appreciate the hard work of those which are working while the rest of us are sleeping.

Yuoki, a restaurant in Germany, is not your everyday all-you-can-eat buffet (自助餐）. For starters, there isn't an actual buffet to fill your plate. Instead, customers are seated at a table and provided with iPads which they can use to order up to five small dishes every ten minutes. They can eat as much as they want for 120 minutes, but having the food served at short intervals (間隔) allows diners to constantly assess how hungry they are and order accordingly, preventing food waste. Also, the owner, Luan Guoyu, believes, “our eyes are bigger than our stomach”, so not being able to see the cooked food at the buffet prevents people from ordering more food than they can actually eat.

But Luan Guoyu's most effective way of fighting food waste, and the one that has attracted media attention, is his ?1 ($1.15) fine for food still left on the plate. “It’s called ‘ all-you-can-eat’ ” he says, adding that the extra charge is not meant to increase his income, but to act as a warning against wasting food.

Luan Guoyu's system is unique in the state of Baden-Wurttemberg, but not in Germany. Okinii, a Japanese-style restaurant in Dusseldorf, has also been charging customer, the same ? 1 tax for unfinished food on their plates since 2013.

With so many people living on the edge of their nations, and food waste becoming a serious problem in developed countries, it will be interesting to see if more restaurants will start carrying out the “eat up or pay up” policy. Even if they give the money from this fine to charity, it would still help them to save money in dealing with waste, so it's a win for everyone.

1.What does the underlined word “assess” in Paragraph 1 probably mean?

A. Doubt. B. Realize.

C. Judge. D. Compare.

2.What will Luan Guoyu do when people can’t finish the food on their plates?

A. He will charge them extra money.

B. He will advise them to eat up the food.

C. He will ask them to take the food away.

D. He will warn them to order less food next time.

3.What is the text mainly about?

A. Various German restaurants.

B. The seriousness of food waste.

C. Secrets of managing a restaurant.

D. Special ways to fight food waste.

4.What does the author think of the “eat up or pay up” policy?

A. Unfair. B. Funny.

C. Reasonable. D. Doubtful.
