A cookie can give one person a sugar rush while barely affecting another person, a new study finds, indicating that a food’s glycemic index（血糖指數(shù)）is in the eater.

People’s blood sugar rises or falls differently even when they eat the exact same fruit, bread, deserts, pizza and many other foods, researchers report. That suggests that diets should be tailored to individuals’ personal characteristics.

The researchers made the discovery after fitting 800 people with blood glucose （血糖）monitors for a week. The people ate standard breakfasts supplied by the researchers. Although the volunteers all ate the same food, their blood glucose levels after eating those foods varied dramatically. Characteristics and behaviors such as body mass index, sleep, exercise, blood pressure, cholesterol levels and the kinds of microbes（微生物） living in people’s intestines are associated with blood glucose responses to food, the researchers conclude.

Those findings indicate that blood sugar spikes （血糖尖峰）after eating depend not only on what you eat, but how your system processes that food.

A team led by a biologist created a computer algorithm(計(jì)算程序) that predicted how much a person’s blood sugar would rise or fall after eating a certain food. When testing on a new group of 100 people, the algorithm correctly predicted the response about 70 percent of the time.

A third group of 26 participants were then given personalized meals. The computer algorithm analyzed each person and then picked diets for 12 of them. A nutritionist chose a “good” and “bad” diet for the remaining participants. Good diets were ones that minimized blood sugar spikes after eating. Bad diets sent blood sugar skyrocketing. The diets contained the same amount of calories. It turned out that foods on the “good” diet for one person were sometimes on another participant’s “bad” list.

1.A food’s glycemic index depends on ______.

A. diets B. sleep

C. health D. eaters

2.Which of the following can best replace the underlined word “tailored” in Paragraph 2?

A. limited B. adjusted

C. applied D. compared

3.The good diets chosen by a nutritionist were the ones that _______ after eating.

A. made blood sugar unchanged

B. sent blood sugar rising sharply

C. reduced blood sugar spikes to the lowest

D. provided body with lots of calories

4.What can be a suitable title for the text?

A. People’s Blood Sugar Rises Or Falls

B. A Good Diet for You May be Bad for Me

C. Diets And Blood Sugar

D. Can a Cookie Give One Person a Sugar Rush?

If Confucius (孔子) were still alive today and could celebrate his September 28 birthday with a big cake, there would be a lot of candles. He’d need a fan or a strong wind to help him put them out.

While many people in China will remember Confucius on his special day, few people in the United States will give him a passing thought. It’s nothing personal. Most Americans don’t even remember the birthdays of their national heroes.

But this doesn't mean that Americans don't care about Confucius. In many ways he has become a bridge that foreigners must cross if they want to reach a deeper understanding of China.

In the past two decades, the Chinese studies programs have gained huge popularity in Western universities. More recently, the Chinese government has set up Confucius Institutes in more than 80 countries. These schools teach both Chinese language and culture. The main courses of Chinese culture usually included Chinese art, history and philosophy (哲學(xué)). Some social scientists suggest that Westerners should take advantages of the ancient Chinese wisdom to make up for the drawbacks of Western philosophy. Students in the United States, at the same time, are racing to learn Chinese. So they will be ready for life in a world where China is an equal power with the United States. Businessmen who hope to make money in China are reading books about Confucius to understand their Chinese customers.

So the old thinker’s ideas are still alive and well.

Today China attracts the West more than ever, and it will need more teachers to introduce Confucius and Chinese culture to the West.

As for the old thinker, he will not soon be forgotten by people in the West, even if his birthday is.

1.The opening paragraph is mainly intended to .

A. provide some key facts about Confucius

B. attract the readers' interest in the subject

C. show great respect for the ancient thinker

D. prove the popularity of modem birthday celebrations

2.We can learn from Paragraph 4 that American students .

A. have a great interest in studying Chinese

B. take an active part in Chinese competitions

C. try to get high scores in Chinese exams

D. fight for a chance to learn Chinese

3.What is the best title for the passage?

A. Forgotten Wisdom in America

B. Huge Fans of the Chinese Language

C. Chinese Culture for Westerners

D. Old Thinker with a Big Future

4.The passage is likely to appear in .

A. a biography B. a history paper

C. a newspaper D. a philosophy textbook
