CFood 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.51. Which of the following statements is NOT true?A. Food when poisoned can make people sick.B.

共用题干Ward off Travel Bugs1 As the holiday season approaches,so does the prospect of jet lag,an upset stomach or sunburn. With care and some help from natural sources,however,it is quite possible to avoid these problems.2 You can start to prepare a couple of weeks before you leave.Food poisoning will make any holiday miserable,but by taking some medicine such as lactobacillus and bifidobacteria,you can reduce the likelihood of succumbing to poisoning brought on by food or water tainted with unfamiliar bacteria.3 By improving the bacteria balance in your digestive tract,you crowd out the pathogenic bacteria and stop them gaining a foothold.The beneficial bacteria also produce gentle but effective natural antibiotics in your gut.4 In many holiday locations you need to remember the basics:drink bottled water,avoid undercooked meat and ensure that food hygiene is adequate.If you do succumb to food poisoning,drink plenty of water to stay hydrated and see a doctor.However,if you detect diarrhea early enough,you might like to try taking about 10 or 15 pancreatic digestive enzymes,which can digest the multiplying bacteria before they take over.5 Taking a teaspoon of silicol gel can also help.This lines the stomach and upper intestinal area arid binds with bacteria and viruses,allowing them to be safely passed out of the gut.When you pack,include grapefruit- seed extract,which is an excellent all-round anti一bacterial,anti-parasitic,anti.viral and anti-fungal agent.6 Your flight can also be made more pleasant.Peppermint oil and ginger capsules ward off motion sickness,but a more delicious option is to nibble on crystallized ginger.if you tend to get earache on take-off and landing,you can use special earplugs with filler that slows down the rate of change in air pressure.7 The greatest concern is"economy class syndrome",the popular name for deep-vein thrombosis, which can lead to blood clots traveling from the legs to the lungs,heart or brain.To reduce this,you need a couple of hours to stay hydrated,and avoid alcohol.8 You can also reduce the severity of inflammation by taking a daily gram of vitamin C with the bioflavonoidquercetin.Vitamin C and quercetin also help to reduce prickly heat.9 Finally,if any adverse symptoms persist while overseas,you should see a doctor.Food-poisoning may pose a problem______.A:when your plane is about to landB:when you are taking tabletsC:when you suffer from food-poisoningD:when you are travellingE:when you are packing for your tourF:when you are having a cold
