小学生可以从3年级开始学习《新概念英语》。

《新概念英语》开始就是实用日常对话，没有更基础的准备过程(例如字母、较简单的句子等)，所以需要一定英语基础才能学习。3年级的学生已经在学校学了两年英语，对英语已经不陌生，而且心智和学习能力也具备了，就可以开始学习《新概念英语》了。

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。

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.
