He has much money at the beginning of every month, but by the end of it he_____ have little left.

     Apparently，we are safe neither at home nor in the business office.We use water in both places，but the research shows that chemicals added to our local water supply to kill harmful bacteria can have unwanted side effects.These chemicals can cause potential harm through drinking and in seemingly harmless activities as cleaning one’s house.They are released(set free)from water by daily actions like water running out of tap，spraying from garden pipes，or splashing in dishwashers and washing machines.As the water is moving.these chemicals are released into the air and then breathed in. Once inside our bodies, they start to affect our health.

　　Does this mean we should stop bathing? No, say the scientists, but we should put all pollution into perspective. Activities at home such as the burning of coal, cooking oil, or even candles release carbon monoxide and particulates such as cigarette ashes which have been proven as harmful to health as working or living near heavy traffic. New tugs, bedding, and even clothing give off that“new smell, ”which is a sure sign of chemicals. In the office, newly applied paint, newly purchased telephones and other telecommunications equipment, and computers release polluting chemicals, too. As offices and homes often have inadequate ventilation (通风), these chemicals can build up to become health problems. Their poisonous effects are only now being slowly recognized.

　　These facts suggest that, at a minimum, proper airing of newly purchased goods with an obvious chemical smell is a wise warning. Home and office windows should be opened during good weather. Even one’s car needs to be ventilated as well while in the garage.

　　We need further research to understand better other potential health dangers, too. For example, the effects of overcrowding of schools (carbon dioxide build-up ), the factory work environment ( an endless list of potentially dangerous substances ), and even home heating and cooling (the air conditioner may be our enemies, not our friends) have only recently started to come to light. Until we understand the effects of our new technological environment better, we can only hope that“there is no place like home.”

“Imagine you are walking along the road. Suddenly you fall over and all the passers-by burst into laughter. You feel very　 36　 and think the world is laughing at you . But in fact, five minutes later, they have　 37　  it ever happened.” The other day when I came across these words in an article, I didn’t agree with the　 38　 .

The author thinks the best thing to do in this kind of　 39  is to pretend nothing has happened, and so avoid　 40　 trouble.

I admit that we should keep　 41　 because “Your tears will only remind others of what happened, while your　 42　 can let them forget it.” But this is far from satisfactory. We should do　43　 to make things better.

I used to be a(n)  44　 girl and not very good at maths. Our new maths teacher asked me a question and I still remember how I hung my head in  45 when I couldn’t answer it.

“If you don’t know the answer, just tell me.” the teacher said, “If you don’t how can I know 　 46　 you know the answer or not?” All of my classmates burst into laughter. My face turned red but the teacher　 47　 me to go to the blackboard and　 48　 what I knew. If I had　 49　 the words in the article, I would have given up. But I tried my best. And to everyone’s  50　, I succeeded! The teacher smiled and said, “Well done! I　 51　 you could do it!”

Since then, I have become active in maths as　 52　 as in other subjects. I used to think doing maths exercises was a waste of time. But now, I know　 53　 I do can make things better. Everyone is the　 54　 of his own fate.

If we make mistakes, we should take on an active　55　 . Laugh, and the world laughs with you; weep(哭泣), and you weep alone.
