倡议书格式包括倡议目的、倡议内容、提出呼吁三部分；首先是称呼语，然后正文部分直接引出倡议目的，接下来列举倡议内容，提出呼吁，最后是落款跟署名。1、引出倡议目的常用in order to引出的不定式短语或用with / for the purpose of引导的介词短语。2、列举倡议内容倡议其实就是提建议，因此，可用be supposed to (应该），it is suggested that... (建议），it would be better if... (如果．．．．．．，那就更好了）等。倡议的内容通常都不只一个，因此可用in addition，besides，additionally，whats more，furthermore，moreover来列举这些内容。3、提出呼吁提出呼吁可用It is (high) time that...句型，该句型中that从句的谓语动词要用过去式或用should加动词原形，should不可省略。也可用in a word引出呼吁的内容。例如：Boys and girls,男孩女孩们，Recently some blood banks across the country are reported to be in short supply of blood.最近，据报道全国各地的一些血库供血不足。Some people hold the wrong idea that donating blood does harm to the donor"s health.
