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.

①跳过空格、通读短文、了解大意

②复读短文、确定语义、判断词形

把握短文大意后再认真复读短文，利用上下文的语境，结合所学过的知识，先确定空格处所需词语的意义，再根据空格在句子中的位置，判断其在句中充当的成分，从而确定所填词的词性，再依据词语搭配和语法规则，判断所填的词的正确形式。

③三读短文、上下参照、验证答案

在短文的每一空白处填上一个词后，将完成的短文再细读一遍，上下参照，连贯思考。把所填的答案放入短文中进行检验，可从上、下文内容是否协调一致、顺理成章，语法结构是否正确无误等进行综合验证，凡有疑问必须重新推敲考虑。
