求英语阅读与写作七上U7 B 翻译

More than two billion people live in Asia! This is about two-fifths of all the people on earth. This number includes parts of Russia,all of China,Japan,India and many other smaller Asian countries.With so many people living in this area it is not surprisiiiing that there are many different languages spoken.
About half of these tow billion people speak Chinese. However,not all oral Chinese is the same.There are many dialects of this language:Pekingese Cantonese and Mandarin,to name but a few.It is quite difficult for the speakers of each dialect to understand each other.Yet,strangely enough,understand each other's speech,they can well understand esch other when they put the words on paper.
It alldepends on the tone of voice that each dialect uses.At times,in one sentence,each word has a different tone,so that the same word might meanone thing in one dialect and another thing in a different dialect.

超过20亿人居住在亚洲！这大约是全球五分之二的人口。这个数字包含部分俄罗斯，中国，日本，印度和其他一些比较小的亚洲国家。有如此多的人口居住在这个区域，也不奇怪又那么多种语言了。
这20亿人口中，大约有一半人口讲汉语。然而，不是所有的汉语都是一样的。也有很多种名副其实的方言;北京话，广东话，普通话。对于语言者来说认识双方的方言都是一件相当困难的事。可奇怪的是，了解双方的演讲，当他们写在纸上，可以很好的理解对方。
这一切都取决于每个方言声调的使用。很多时候，一个句子，每个单词都有不同的声调，因此同一个单词可能在方言中是一种意思，在另外一种不同的方言是另一种意思。
