“You are what you eat,” says the old saying. So how can we know what food is healthy? Unluckily, a lot of food that looks good may have pollution. Where is the pollution from? It has something to do with how people produce food: growing it on the farm, processing (加工）it in factories, and making it ready for you to eat.

Here’s what happens:

Most farmers use chemicals(化學藥品) to stop their crops from getting sick. Many of these chemicals remain in the food that you eat. Some people believe this may cause cancer. These chemicals may also pollute water and air, and kill animals and even people by accident.

Most drinks are just flavored water (加味水). Every drink coming in plastic bottles which you then throw away means a waste. Sugary drinks make you fat.

In the factories, much of what you eat and drink gets messed. Often things are put into food to make it delicious and look good but they might be harmful to people. And some food like meat often gets polluted by bacteria. What you can do:

Try to get organic (有機的）food. Organic food doesn’t have any ingredients (成分）that are bad for the land, air or water. Don’t eat processed food or drinks. Eat fresh food whenever you can and cook at home.

1.Which of the following processes cannot make the food be polluted?

A. Growing B. Eating C. Processing D. Making

2.What may be the results of putting chemicals on crops?

①Crops may not get sick.

② The chemicals may remain in the food.

③ People may get sick after eating crops that have chemicals in them.

④ The chemicals may pollute the environment.

A.②③ B.①②③ C.②③④ D.①②③④

3.Things are often put into food to make it_____ according to the passage.

A. delicious and look good

B. become healthier food

C. much heavier

D. be cooked easily

4.Which of the following is NOT true?

A. A lot of food that looks good isn’t good.

B. Organic food doesn’t pollute the environment.

C. Some ingredients in drinks may be bad for people’s health.

D. All the food has pollution.

5.What does the writer advise people to do?
