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 poisoning 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 release(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, processed, or prepared. For example, many farmers spray chemicals on crops to kill weeds and insects. Some people may have a bad reaction to those chemicals when they eat the crops.
Some plants and animals contain natural poisons that are harmful to people. These include 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.
1.Which of the following statements is NOT true?
A. Food when poisoned can make people sick.

Every new person added to the planet needs food, water, clothes, and so on.1. Those things require extra natural resources,including land and water. But Earth’s riches are limited. Less than 1 percent of Earths water can be used for drinking and washing. One out of every thirteen people around the world does not always have enough clean water. 2..Too many people are using too much water, especially in the already dry areas of the southwestern United States.
Food shortages(不足)are even more common. Worldwide, one out of every seven people does not get enough to eat. 3.. Over time, the soil loses its nutrients (营养)and the farmland becomes useless for growing food. As the world becomes more crowded (拥挤的), more land is needed to make way for growing cities.4.. That’s a problem because trees help take in a gas called carbon dioxide. Humans produce carbon dioxide by burning coal and oil. Fewer trees mean more carbon dioxide in the atmosphere. The buildup of carbon dioxide traps heat and pollution above Earth.
5., although every person uses the planet's resources. The richest billion people, Americans especially, use the most resources. They also produce the most waste.
A.Forests are cleared away
B.Some people use a lot more than others
C.Water shortages have hit many parts of the world
D.Water pollution is a serious problem in some areas
E.More trees should be planted to handle air pollution
F.Huge needs for food force farmers to overuse their land
G.More people mean more cars, roads, schools, hospitals, and stores

Some snakes eat other snakes, even poisonous ones. The poison does not do them any harm(伤害). Snakes can swallow(吞下) things that are bigger around than they themselves are. This is possible because the jawbones(腭骨) are loosely joined, and the mouth can stretch(伸展)to make room for a fat animal. The snake’s slim body stretches to make space for the animal when it is inside.
Many snakes eat birds’ eggs or frogs(青蛙). Others eat pests(害虫), mice and other animals that harm crops on farms. Because snakes do this valuable work, you should never kill one. It is too dangerous for you to kill a poisonous one. Leave that job to experts.
1. Which of the following groups of food is usually had by a snake?
A. Mice, crops, birds’ eggs.
B. Pests, frogs, some animals, plants.
C. Birds’ eggs, frogs, all animals, other snakes.
D. Mice, frogs, pests, some animals, other snakes.
2.We should not kill a snake because________
A. it is poisonous
B. it can do something useful for man
C. it will strike you in return
D. we are not experts
3.Snakes may do some valuable work by________
A. eating pests, mice and some harmful animals
B. doing harm to other animals
C. eating birds’ eggs and frogs
D. both A and C
4.In writing this passage the writer mainly wants us to________
A. have a better impression(印象) about snakes
B. like snakes
C. kill snakes with the help of experts
D. regard snakes as one of man’s best friends

Sometimes we can get so caught up in the stress and worry of our personal lives that our minds become too confused to operate effectively.This is especially dangerous in a test-taking situation.After hours of reading and studying,our brains can lock up in a state of overload.
In a stressful situation it's often a must to clear your mind completely to allow your brain to refresh itself and recalibrate all of its functions.But when you're tense,clearing your mind isn't so easy!Try this relaxation technique if you think your brain has seized up from information overload.
1.Set aside at least five minutes for quiet "clearing" time.If you're at school,see if you can put your head down somewhere or find an empty room or quiet space.If necessary,set a watch (or phone) alarm or ask a friend to tap you on the shoulder at a designated time.
2.Think of a time or place that puts you into a complete state of peace.This place will vary from person to person.Have you ever sat on the beach watching the waves come in and realized you've "zoned out" fora while?This is the sort of experience you're looking for.Other experiences that make us zone out could be: Sitting in the dark and staring at Christmas tree lights—remember how peaceful that feels?
3.Cover your eyes and go to your "place".If you are at school preparing for a test before class,you may simply rest your elbows on the desk and put your hands over your eyes.For some people,it may not be a good idea to put your head down.(You might fall asleep!)
Don't let any thoughts creep into your head.As soon as you start to think about a test problem,clear away the thought and concentrate on your peaceful place.
4.Snap out of it!Remember,this is not nap time.The point here is to refresh your brain.After five or ten minutes of clearing time,take a brisk walk or take a drink of water to re-energize your mind and body.Stay relaxed and resist the urge to think about the things that are stressing you out or clogging your brain.Don't let your brain go back to freeze-out.
Now go on with your test or study session refreshed and ready!
