    Food Poisoning

    Food sometimes gets poisoned with harmful things,A person who eats such food can get an illness called
    food poisoning. Food poisoning is usually not serious,but some types are deadly.The symptoms of food poi-
    soning usually begin within hours of eating the poisoned food.Fever is one of the most common symptoms.
    Certain microorganisms(微生物)cause most types of food poisoning. Bacteria and other microorganisms
    can poison eggs,meat,vegetables,and many other foods.After entering the body,these tiny living things re-
    lease(释放)poisons that make people sick.
    Some chemicals can also cause food poisoning. They are often added to food while it is being grown,pro-
    cessed,or prepared.For example,many farmers spray chemicals on crops to kill weeds and insects.Some
    people may have a bad reaction to those chemical、when they eat the crops.
    Some plants and animals contain natural poisons that are harmful to people.These includo certain kinds
    of seafood,grains,nuts,seeds,beans,and mushrooms.
    When people handle food properly,the risk of food poisoning is very small.Microorganisms multiply rapidly
    in dirty places and in warm temperatures.This means that people should never touch food with dirty hands or
    put food on unwashed surfaces.Food should be kept in a refrigerator to stop microorganisms from growing,
    Meat needs to be cooked thoroughly to kill any dangerous microorganisms. People should also wash food covered
    with chemicals before eating it.Finally,people should not eat wild mushrooms or other foods that grow in the
    wild.Some of these foods may contain natural materials that are poisonous to humans.In addition,some types
    of fish can be poisonous.
    Most people recover from food poisoning after a few days of resting and drinking extra water. If people
    eat natural poisons,they must go to the hospital right away to have their stomachs emptied.

    From Paragraph 5,we can learn that_______________.
    A:mushrooms should not he eaten
    B:vegetables are safer than meat and seafood
    C:natural poisons are more dangerous than chemicals
    D:different types of food should he handled differently

    问答题
    ◆Topic 12:Fast Food  Questions for reference:  1) Fast food is a good reflection of the quick-paced modern society. What role does fast food play in China?  2) Why is fast food so popular? What are the demerits of fast food?  3) What attitude should we have towards fast food?

    正确答案: 【参考答案】
    Fast food is becoming more popular in China, especially among children and teenagers. Today, it’s certainly difficult to think of any other single thing that represents the fast pace of modern society as powerfully as fast food.
    There are several reasons for its popularity. First, it is very convenient and saves a lot of time. The trends of modern society seem to all point to one ultimate goal-saving time, and fast food well serves this purpose. You just go into a fast food restaurant, order your food, and your food is ready in no time. You can either eat it there or take it away. Second, its popularity is also attributed to the clean and comfortable environment of fast food restaurants, the excellent service, and the guaranteed quality of food.
    However, in terms of nutrition, fast food is far from satisfactory. It usually does not compose a balanced diet and is low in nutritional value. Thus, doctors suggest that people, especially children, eat fast food as little as possible. Although cooking at home is time-consuming and the following washing-up tiresome, it offers healthy and delicious meals your body likes and needs. Fast food is only a good choice when you are in a hurry and turn to it once in a while.
