学练快车道口算心算速算天天练系列答案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.

When I was growing up, I was embarrassed to be seen with my father. He was badly crippled (跛脚), and when we would walk together, his hand on my arm for balance, people would stare, I would be ashamed of the unwanted attention. If ever noticed or bothered, he never let on.
It was difficult to walk together—and because of that, we didn’t say much as we went along. But as we started out, he always said, “You set the pace. I will try to follow you.”
Our usual walk was to or from the subway, which was how he got to work. He went to work sick, and even in bad weather. He almost never missed a day, and would make it to the office even if others could not. It was a matter of pride for him.
When snow or ice was on the ground, it was impossible for him to walk, even with help... Such times my sister or I would pull him through the streets of Brooklyn, N.Y., on a child’s sleigh to the subway entrance. Once there, he would try to grasp handrail until he reached the lower steps that the warmer tunnel air kept ice free. In Manhattan the subway station was the basement of his office building, and he would not have to go outside again until we met him in Brooklyn on his way home. w.w.w.k.s.5.u.c.o.m
When I think of it now, I am surprised at how much courage it must have taken for a grown man to suffer from shame and disability. And I am also surprised at how he did it—without bitterness or complaint.
He never talked about himself as an object of pity, not did he show any envy of the more fortunate or able. What he looked for in others was a “good heart”, and if he found one, the owner was good enough for him.
Now that I am older, I believe that is a proper standard by which to judge people, even though I still don’t know exactly what a “good heart” is. But I know the times I don’t have one myself.
He has been away for many years now, but I think of him often. I wonder if he sensed my reluctance to be seen with him during our walks. If he did, I am sorry I never told him how sorry I was, how unworthy I was, how I regretted it. I think of him when I complain about my troubles, when I am envious of another’s good fortune, when I don’t have a “good heart”.

Two years ago my grandmother was going to turn 75. My family discussed what the best way to celebrate was. Should we throw her a party? Should we take her on a trip? We remembered that she had touched so many people's lives, and there were so many people for her to consider. Then someone got the idea that we should include everyone in the celebration by turning it into a tribute(献礼) to my grandmother.x k b 1 . co m We secretly sent out letters to the people in Grandmother's address book and asked them to send a letter with a memory that they had shared with her. People sent us letters with poems, stories and pictures. The deep feeling that was shared through the response surprised us. We compiled(编辑)these letters into a memory book and amazed her with it on the morning of her birthday.
The unusual thing about my grandmother's friends was not the number that she had, but the connection they shared. In many ways this book of friendship was the greatest achievement of my grandmother's life.
I believe that developing true friendships is one of the most important things that anyone can do in one's lifetime. It is not a matter of the number of friends one has, but the quality of the bonds. If one has had at least one true friendship before dying, then one can say one has lived a successful life. I have made many friends and I believe I have begun to develop the same types of friendships my grandmother kept up over her lifetime. I only hope that I will be as successful as she has been.
