You may not realize it，but you are doing much more than just studying，when you are at school． School is also the place where you learn to get along well with people． But this is not al-ways easy． What can you do if you just don-t like one of your classmates? If you discover that you have problems getting along with your classmates or friends，the most important thing to learn is tolerance(宽容)． Tolerance is the ability(能/J ) to realize and respect(尊重) the differences in others． We can not change the way that other people do，so it is important to learn to live happily with them．

Tolerance will make everyone get on better with each other． Getting to know someone may help you understand why they do things differently． Something different does not exactly mean that it is bad． Tolerance teaches us to keep an even temper and open mind ．

You need to remember an old saying，"Treat others how you want to be treated"． You would like to be treated kindly by your classmates，so it is important to treat them kindly too．

If you tolerate(宽容) something，it does not mean that you have to like it． No one is asking you to change who you are or what you believe in． Tolerance just means that you should respect the differences in others and not try to make them change．

It is important to practice tolerance，because it will make everyone's lives easier． Learn to accept(接受) people for their different abilities and interests． The world is very different，and practicing tolerance in your own school and city can help you make a difference．

Passage Four

Most people do not think of fishes and other sea animals as having voices, and of those who are aware of the fact that many of them can "speak", few understand that these "conversations" have significance. Actually, their talk may be as meaningful as much of our own. For example, some sea animals use their "voices" to locate their food in the ocean expanses (广阔的区域); others use their "voices" to let their fellows know of their locations; and still others, as a means of obtaining mates. Sometimes, "speaking" may even mean the difference between life and death to a sea animal. It appears in some cases that when a predator (食肉动物) approaches, the prey (被捕的动物) depends on no more than the sounds it makes to escape.

Fish sounds are important to man, also. By listening to them, he can learn a great deal about he habits of creatures that make them, the size of the School they form, the patterns of their migrations, and the nature of the environments in which they live. He can also apply this nformation to the more effective utilization of the listening spots he has set up to detect enemy submarines (潜水艇). A knowledge of fish sounds can avoid confusion and unneeded effort when a "new" sound is picked up and the sound sentry (哨兵) must decide whether or not to call an alarm.
