4．結(jié)束語(yǔ)：結(jié)束語(yǔ)與正文的結(jié)尾語(yǔ)不一樣，它要寫(xiě)在結(jié)尾語(yǔ)的下一行，位于書(shū)信的右下角，后面用逗號(hào)。常用的結(jié)束語(yǔ)有：Yours sincerely/faithfully/truly；Sincerely/Truly yours；Yours等。
5．簽名：簽名寫(xiě)在結(jié)束語(yǔ)的下一行，與結(jié)束語(yǔ)對(duì)齊，也就是簽上寫(xiě)信人的名字。

As a boy of 17, I am outgoing, good at English and have experience of working well with children aged from 7 to 12.I think it is a kind of winwin activity.For one thing, I can help take care of the children.For another thing, I can improve my English, make more friends, and enrich my life during the summer vacation.
I am looking forward to your early reply.
