The volunteering spirit has spread among the Chinese people in recent years, especially among young people.

Volunteering is of tremendous benefits to both those in need and society. Take the Wenchuan Earthquake as an example. Hundreds of thousands of volunteers play an active role in Wenchuan quake-hit areas. And they contribute daily necessaries, offer medical help and psychological help to the disaster relief work.

Besides, volunteering would be beneficial to the volunteers themselves~ Getting involved in volunteering, volunteers will be exposed to a new environment, and they can learn how to work well in a team, how to improve their interpersonal skills and organizational skills, all of which are critical for their professional growth.

As a college student, I sincerely hope that everyone would join the volunteering work. It is not only good to our society, but also a chance for us to grow and to learn.

人教版英语教材是美式英语。

人教版英语教材一般是就教科书意义而言的，相对于其他出版社出版的教科书而言，指的是由人民教育出版社出版的教科书版本。而美式英语较英式英语来说更为口语化，读音开放，有特性。

过去的四百年间，美国、英联邦以及不列颠群岛使用的语言都在不断地发生变化，最终演变成了英式英语和美式英语。两种英语在音标、语法、词汇、拼写、标点、谚语、日期和数字的形式等等许多方面都有不同。

对于人教版的高中英语教材，单词拼写是按照英式英语标准来的，磁带录音用的却是美式英语。阅读材料里比较口语化的语言以美式英语居多。
