练好英语听力，可通过以下方法：

①听力与阅读是相通的，必须有大量且牢固的英语词汇量基础;

②告别哑巴式英语，在背单词、读课文的时候一定要读出声音来。同时，注意发音要标准;

③拒绝中式英译法，增加自己的英文句子储备，养成英语思维。

①信头

指发信人的地址和日期，写在信纸的右上角。

②称呼

指对收信人的地址和称呼。写在信头之下，从信纸的左边开始。写信给熟悉的人，如王明一般用Dear Wang Ming 或Dear Mr. Wang。

③信的正文

指信的主体部分，从称呼的下一行到结束语前，第一段顶头写。

④结束语

指正文下面的结束客套话。常用Yours sincerely，Yours ever或者Yours或Yours truly等。

⑤签名

指发信人的签名，写在结束语的下面。

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.
