Unit 1 Food for thought
一、阅读理解（本大题共4小题，共8.0分）
A
Chinese cuisine is widely known and enjoyed in the world. But there is one interesting idea of Chinese food which is almost unheard of in the West, and which is becoming increasingly ignored by the youth of the East— the ancient custom of "tonic(滋补品) food".
Tonic food is food which is to improve one's well-being particularly at times when one is more likely to fall ill. For example, it was once the custom for new mothers to eat sesame-oil chicken soup every day for the first month after giving birth. It was believed that this dish would be helpful in reducing the pain, improving the circulation (血液循环), and warming the body. Some foods, such as goat meat and ginger, are seen as "hot", while others, such as Chinese cabbage and radish, are seen as "cold". One should be careful not to eat too much of either hot or cold food. However, how much "hot" or cold food one should eat depends on the time of the year, how the food is prepared and what it is prepared with, and the individuals health.
The custom of using tonic food for a healthier life also influences the catering industry. Traditional Chinese medicines, such as the wolfberry (枸杞子), can be found on the menus of restaurants, either added to fruit tea or as an addition to a dish. They attract customers, such as overworked office staff, who are in need of a modest pick-me-up.
So, whether you need to build up your strength with a large helping of chicken soup, or increase your mental powers with a serving of fish soup, you may find that the ancient Chinese custom can be just the tonic food you are looking for.
1. What is the present situation of tonic food
A. It is catching less attention.
B. It is well known worldwide.
C. It is enjoyed by many young people.
D. It is becoming increasingly popular.
2. What is believed to be helpful for new mothers
A. Chinese cabbage. B. Fruit tea.
C. Sesame-oil chicken soup. D. Fish soup.
3. Which can best explain "catering" underlined in paragraph 3
A. Medicine. B. Agriculture. C. Tourism. D. Restaurant.
4. What is the text mainly about
A. The charm of Chinese cuisine.
B. An introduction of tonic food.
C. The popularity of Chinese custom.
D. Differences between "hot" and "cold" food.
二、阅读七选五（本大题共5小题，共10.0分）
Keep Your Diet Healthy When You Take a Flight With so much time spent at airports, it has become very difficult for people to eat right. (1) But it can be tough.
In terms of saving money and eating right, the best bet is bringing food from home, whether it's something you prepared yourself, or healthy store-bought snacks. (2)
Planning ahead is always the healthier choice. (3) Homemade food tastes better and healthy food from home also is better than what airlines sell and offer on flights, such as cans of overpriced and oily potato chips or boxed sandwiches with processed meat and cheese.
Maybe you intended to pack a bag of healthy snacks for your time at the airport but you were so tired that you left the bag on the kitchen counter. Don't worry. Airports do have healthy choices, although they are pricier than the food you bring from home. Many airport stores offer healthy grab-and-go selections these days, including fresh fruits like bananas and apples, salt-free nuts and so on. (4) Here are some quick and tasty suggestions from our experts:
(5) Bananas are the easiest to carry. Bring along a little container of peanut butter. Small oranges, carrots, peas and red, orange and yellow peppers are tasty and healthy too. Buy a bottle of water or two. And once on the plane, choose water rather than soft drinks.
A.Flying is so stressful these days.
B.Fast-food restaurants offer healthier menu choices.
C.Fresh fruits and vegetables are a traveler's best friends.
D.So if you are pushed for time, you can find one of these choices.
E. Planning ahead allows you to control what goes into your meals.
F. Even if you fly once a year, finding healthy choices at the airport is also important.
G. With a little preparation, you can improve what you eat at the airport and save money.
5. A. A B. B C. C D. D E. E F. F G. G
