【正文】 river a bowl or a glass, and then go a fire so that you might make yourself some hot tea marks (標(biāo)志 )as you go to the river so that you can find your way back C Fire can help people in many ways. But it can be very dangerous. Fire can heat water, warm houses, give light and cook. But fire can burn things, too. It can burn trees, houses, animals or people. Sometimes big fire can burn forests. Nobody knows for sure how peole began to use fire. But there are many interesting stories about the first time a man or a woman started a fire. One story from Australia tells about a man very, very long time ago. He went up to the sun by a rope (繩子 ) and brought fire down. Today people know how to make a fire with matches (火柴 ). Children sometimes like to play with them. But matches can be very dangerous. One match can burn a piece of paper, and then it might burn a house. A small fire can bee a big fire very fast. Fire kills many people every year. So you must be careful with matches. You should also learn to put out fires. Fires need oxygen (氧氣 ). Without oxygen they will die. Cover a fire with water, sand or sometimes with your coat. This keeps the air away from a fire and kills it. Be careful with fire, and it will help you.

This arises from the different ways in which they consider things， persons，events and the resulting effects upon their minds. People who are to be happy fix their attention on the convenience of things：the pleasant parts of conversation， the well prepared dishes， the goodness of the wine and the fine weather. They enjoy all the cheerful things. Those who are to be unhappy think and speak only of the opposite ， they are continually dissatisfied. By their remarks， they sour the pleasure of society， hurt many people，and make themselves disagreeable everywhere. If this turn of mind was founded in nature， such unhappy persons would be the more to be pitied. The intention of criticizing and being disliked is perhaps taken up by imitation. It grows into a habit， unknown to its habit may be strong， but it may be cured when those who have it realize its bad effects on their interests and tastes. I hope this little warning may be of service to them， and help them change this habit. Although in fact it is chiefly an act of the imagination， it has serious results in life since it brings on deep sorrow and bad people offend many others；nobody loves them， and no one treats them with more than the most mon politeness and respect. This frequently puts them in bad temper and draws them into arguments. If they aim at getting some advantages in social position or fortune， nobody wishes them success. Nor will anyone start a step or speak a word to favor their hopes. If they bring on themselves public objections， no one will defend or excuse them，and many will join to criticize their wrongdoings. These should change this bad habit and be pleased with what is pleasing， without worrying needlessly about themselves and others. If they do not， it will be good for others to avoid any contact with ， it can be disagreeable and sometimes very inconvenient，especially when one bees mixed up in their quarrels. 33． The phrase “sour the pleasure of society” most nearly means “________” ． A． have a good taste with social life B． make others unhappy C． tend to scold others openly D． enjoy the pleasure of life 34． If such unhappy persons insist on keeping the habit， the author suggests that people should ______
