讲述了志愿服务的好处。Volunteer Service在文章反复出现。综上所述可知本文主要讲述了西部的志愿者服务。分析选项可知A项符合题意，故选A项。

【点睛】选择标题在英语阅读理解中属于主旨大意题，是一种深层理解题。要求考生在通读全文的基础上，认真分析文章大意及作者的写作意图。通常情况下，标题要有根据性，针对性和醒目性的特点。所谓概括性，就是指标题应最大程度上覆盖全文，囊括文章的主要内容，体现文章的主题。针对性就是对标题外延的一种界定，标题要直接指向文章的主要特点。而醒目性是为了吸引了读者的注意，唤起读者对文章阅读的兴趣。

确定最佳标题的方法。在阅读文章时，要注意文章中反复出现的或强调的信息，寻找与文章大多数内容相关的信息。找出覆盖全文的核心词汇，看选项内容是否切中文章的中心论题。也就是要看选项内容与作者的写作目的是否一致。如第4小题，文章反复出现的单词是stress，这与选项A中的Volunteer Service相照应。

寻找文章的主题句。文章主要论题的关键是找到文章的主题句。主题句通常在文章的首段，也可能在文章的末段，在文章的某一段落，或分散在文章的各个段落中。如果每个段落都有主题句，那么把各段落的主题句的中心集中起来，即为全文的主题句。本文的中心句在首段的末句"Every year, thousands of people in the west offer volunteer service. Volunteering greatly strengthens the community because it helps the old, the young, the weak, the sick, and the disabled and the injured to solve problems."这就是对标题"Volunteer Service in the West"的回答。

　　They were in their late forties when he died, and she began talking about a time in their life almost twenty years earlier. She had quit her job to obtain her master's degree, and her husband never hesitated in his support.

He held down his own job and also did the cooking, cleaning, and other housework
