    Researcher Heike Bischoff-Ferrari wrote in the report.”it is possible for people to increase the amount of vitamin D earlier to keep healthy.”

 My good friends, if you ‘re too busy , maybe it’s time you slowed down and enjoyed a meal with a friend. Try to get away from fast food and choose slow food.

    For years, the pace(节奏)of life has increased for many people. They are too busy to cook.Luckily, there are business people who take the chance to provide a “fast ” way to deal with the problem. You can go to the supermarket and buy cooked food. All you have to do is to heat it and you can enjoy your meal in 10 minutes.

Still too slow ? OK, just go to a fast-food restaurant , order your meal and within 5 minutes it will be made for you.

    The problem is health. Fast food has much more fat, sugar,salt, oil and calories (卡路里), and far fewer vitamin's(维生素)than homemade food. And so, since people have always wanted to live longer,a small but growing population is choosing not only fresh food, but also organic(有机的)food.

    Another reason for changes in eating habits is social. Over the centuries,mealtime has been used to visit , laugh and learn. However, today most of us are having a very different lifestyle! Some people have realized it and they are looking for ways to return to that. Goodbye, McDonald’s.

    Finally, it makes you feel good to plan your meal, cook your meal and see your meal looking like the picture in your cook book. So if you’re too busy, maybe it’s time you slowed down and enjoyed a homemade meal.

1Why do many people buy cooked food in the supermarket ?

    A. It’s delicious.                  B. They think it’s a fashion to eat it.

    C. It saves them time.              D.it save them money. 

2 The writer thinks we just have to wait _____ minutes at most for our meal in a fast food restaurant.

    A. five .        B.fifteen.          C.eight.       D. fifth 

3 Fast food is low in _________ ?

    A. salt .        B.calories .        C.sugar.       D. vitamins .

4 What does the underlined word “that” in Paragraph 5 mean ?

A. Eating in a fast-food restaurant .

B. Visiting friends.

C. Having a different lifestyle. .

D.Enjoying slow food.
