阅读理解。 

     You're driving home from work.  You're tired, and the thought of shopping for food and cooking

dinner makes you even more tired. Suddenly you see a brightly lit sign: "Hamburgers! Fries! Shakes!"

Your hands are holding the wheel. Which way are you going to turn?

     If you turn toward the hamburgers, you'll find much of what you're looking for. You won't have to do

any shopping, and you won't have to do any cooking. Not only that, but you won't even have to clean up

after you've eaten.

     Of course, the fast food will be about three times as expensive as food you buy in a store and maybe

half as nutritious (有营养的) as food you cook at home.  That's because you've got to pay for someone

else to buy the food and cook it, and for those unpleasant containers that save on cleanup.  Fast food is

also less nutritious because the meals are not as balanced (均衡的) as those you can prepare at home.

Fat content and calories are high, and the meals don't have enough fresh fruits and vegetables. Fast-food

restaurant owners, who always care about money, also mav cut corners on quality of foods.

     Worst of all, those hamburgers will be the same old hamburgers as you've had a million times

before. With home cooking, you can eat anything you want, not just what you can find in fast-food

restaurants.

     The choice is yours, of course.  However! if you want to be healthy, try cooking at home.

1. When you think of ______. you feel even more tired after work.

A. eating the fast food

2. The fast food will be' about three times as expensive as ______.

A. She advises us to eat more fast food.

B. She tells us how to choose fast food.
