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.W_w w.k*s*5 u.c@o m
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.W_w w.k*s*5 u.c@o m
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 the very beginning, Martin felt that he was bound up with（与……紧紧地在一起）his lovely little patient. One day, following some tests , Betty gave the doctor a big hug（拥抱）.

　　A few months later the doctor removed not only the tumour（肿瘤）, but also the entire lower left side of Betty’s gum（牙龈）and jawbone. Because Betty was so young, Martin was hopeful that her jawbone might regenerate.

　　Within three months, Betty’s tumour grew as large as an orange, changing the natural appearance of the left side of her small, delicate （ = thin; not strong）face. Soon she couldn’t even close her mouth, and as her eating problems worsened, Betty ‘s weight dropped from 20 kilos to 15. Martin knew from experience that it might invade the brain.

　　The only other possibility was thorough radiation therapy （放射疗法）. Night after night, Betty's father gave her injection, but the tumour remained as big as ever. Then one evening. Morgan noticed that the tumour had begun to change. It was actually becoming smaller! For two months her tumour appeared to be going away for ever.

We were on our way home from Houston one Saturday morning. We decided to stop at a local gas station to get coffee and something to snack on since it was a good hour and a half before we got home.

When we were done, we got back into our car and before I started it, we noticed a man standing outside in front of the building. He was a homeless man with worn clothes and it looked like he had gone in and gotten himself some coffee or something warm to drink since it was cold this time of the year. He must have not had enough money to get something to eat.

Then a dog walked up to the front of the building. I could tell she was a “she”, because you could tell that she had baby dogs. She was terribly in need of something to eat and I felt so bad for her. I knew if she didn’t eat soon, she and her baby dogs would not make it.

I and my wife sat there and looked at her. We noticed that people walked by and didn’t even pet her, like most people do when they walk by an animal in front of a store. We still did not do anything. But the homeless man, who I thought did not buy himself anything to eat, went back into the store. And what he did brought tears to me and my wife. He had gone into the store and with what money he may have had, bought a can of dog food and fed that dog.

Every object tells a story. Even the most ordinary objects can present to us powerful images. Sometimes it is the ordinary nature of these objects that actually makes them so extraordinary. Such is the case with an old leather shoe in a museum in Alaska. At first glance it does not look like much. It is a woman’s shoe of a style popular in the 1890s. But what is unique(独特的) about this shoe is where it was found. It was discovered on the Checkout Pass, the famous trail used by the people seeking gold in Alaska. Who it belonged to or why it was left there is not known. Was it perhaps dropped by accident as the woman climbed up the 1500 stairs carved outface? Or did she throw away goods that she didn’t need in order to travel lighter?

Over 100, 000 people with “gold fever” made this trip hoping to become millionaires. Few of them understood that on their way they would have to cross a harsh wildness. Unprepared for such a dangerous journey, many died of starvation and exposure to the cold weather.

The Canadian government finally started requiring the gold seekers to bring one ton of supplies with them. This was thought to be enough for a person to survive for one year. They would carry their supplies in backpacks(背包) each weighing up to fifty pounds; it usually took at least 40 trips to get everything to the top and over the pass. Whoever dropped the shoe must have been a brave and determined woman. Perhaps she was successful and made it to Alaska. Perhaps she had to turn back in defeat. No one will ever know for sure, but what we do know is that she took part in one of the greatest adventures in the 19th century.

1. The ordinary woman’s leather shoe is considered unusual because _______.

A. it was an important clue to life in the past B. it was found on a famous trail

C. it at one time belonged to a VIP D. it was a fashionable shoe at that time

2. According to this passage, many people who went to Alaska _______.

A. eventually became millionaires B. brought with them many shoes

C. had conflicts with the Eskimos D. were not properly equipped

A. they would not die of hunger and cold

B. the army would have enough food for fighting a war

C. they would change these goods with the Eskimos

D. the supplies would make Alaska rich

4. No matter what happened to the woman who owned the shoe, _______.

A. she must have lived a happy life

B. she certainly dropped the shoe on purpose

C. her adventurous spirit is definitely admired

D. her other shoes were equally fashionable
