This sign + means that you will add some numerals. This sign—means that you will take one numeral away from another. You will subtract（减去）. What will you do when you see x and… ?Our signs are easy to read. They are easy signs to remember. Look at these two signs… .The ancient Egyptians used these signs. A picture of a leg walking to the left told them to add some numerals. A picture of a leg walking to the right told them to subtract. In the 1500s people used this printed（印刷的） sign to add numerals. After a while the sign began to look like this… .Later， the sign became +.How much is 2+2?the signs are very different， They mean very different things.（ ）
2、 右腿走路这里有一些符号+-x…，符号非常不同。它们的意思完全不同。当你看到他们时，你知道该怎么做。这个符号+表示你要加一些数字。这个符号意味着你将把一个数字从另一个数字中去掉。你要减法。当你看到x和…，你会怎么做？我们的招牌很容易看。它们很容易记住。看看这两个符号……古埃及人用过这两个符号。一张左腿行走的照片告诉他们添加一些数字。一张右腿行走的照片让他们减法。在16世纪，人们用这个印刷的符号来添加数字。过了一会儿，这个符号开始像这样……后来，这个符号变成了+。2+2是多少钱？符号非常不同，它们的意思完全不同。（ ）

5、 A Trip to the ForestOne day Bob took two of his friends in-to the mountains. They put up their tents (帐篷) and then rode off to a forest to see how the trees were growing.In the afternoon when they were about ten kilometres from their camp(营地)，it start-ed to snow. More and more snow fell. Soon Bob could hardly see his hands before his face. He could not find the road. Bob knew there were two roads. One road went to the camp，and the other went to his house. But all was white snow. Everything was the same. How could he take his friends back to the camp?Bob had an idea. The horses! Let the horses take them back! But what would hap-pen if the horses took the road to his house? That would be a trip of thirty-five kilometres in such cold weather!It was getting late. They rode on and on. At last the horses stopped. Where were they? None of them could tell. John looked around. What was that under the tree? It was one of their tents!The horses stopped because they knew that they had got to the camp.（ ）
6、 森林之旅一天，鲍勃带着他的两个朋友到山里去了。他们搭起帐篷，然后骑马到一片森林里去看树木的生长情况。下午，当他们离营地大约十公里的时候，天开始下雪了。下雪越来越多。很快鲍勃几乎看不见他的手在脸前。他找不到路。鲍勃知道有两条路。一条路通往营地，另一条路通往他的家。但一切都是白雪。一切都一样。他怎么能把他的朋友带回营地？鲍勃有个主意。马！让马把它们带回去！但是，如果这些马走这条路去他家，会发生什么呢？在这样寒冷的天气里，那将是35公里的旅行！已经很晚了。他们不停地骑马。马终于停了下来。他们在哪里？他们谁也说不出来。约翰环顾四周。树下是什么？那是他们的帐篷！马停了下来，因为他们知道他们已经到了营地。（ ）
7、 Two farmers were on their way home one evening after a hard day’s work. Both were tired. They happened to look up at the sky and saw a black cloud overhead. “Ah! ” said one farmer，“tomorrow we shall have rain and the rice will grow well. ” The second answered，“Nonsense (胡说)，the rain will only kill the crops (庄稼). ”So they began to quarrel (争吵). Just then a third farmer came along and asked them why they were quarreling. Both farmers explained about the black cloud. “What cloud? ” asked the third farmer. They all looked at the sky. The cloud was no longer there.The two farmers were going to work.（ ）
8、 一天晚上，两个农民劳累了一天，正在回家的路上。两个人都很累。他们碰巧抬头仰望天空，看见头顶上有一朵乌云。“啊！一位农民说：“明天我们会下雨，稻子会长得很好。”。第二个回答说：“胡说，下雨只会害死庄稼。”。“于是他们开始争吵。就在这时，第三个农夫走过来，问他们为什么吵架。两位农民都解释了乌云的情况。“什么云？第三个农夫问道。他们都看着天空。云已经不在了。那两个农民要去工作。（ ）
9、 Renting a color television makes more sense than buying. Here’s why:1. The longer you rent (租)，the less you pay. Each year the monthly rate is reduced. You can reach a low rate of not much more than $12 a week.2. Service is fast and free. We can have your set installed (安装) in two days. If anything goes wrong，we’ll have it fixed the same day or lend you another set while we’re mending it. And don’t forget: service and spare parts are free!3. If you don’t have an aerial (天线)，we’ll install one for you，and that will be free，too. All you have to pay is the installation charge (安装费)!4. You can choose from all kinds of models，and what’s more，if after a certain period of time，and you would like a new model，you can change. How’s that for service?5. No deposit (押金) is needed. You pay only the monthly rental fee. But if you pay in advance，you can save money. Pay twelve months’ fees when you begin to hire，and we’ll give you a month’s hire without charge.6. If you decide that you want to stop renting and buy the set you have on hire，this can be arranged—with a generous allowance (折扣) for the fees already paid.This passage is a advertisement .（ ）
