例如：近期“公筷行动”公益广告每天在央视频道黄金时间播出。为了号召大家在用餐时间使用公筷，请你以学生会的名义向全校师生写一封英文倡议书并刊登在校英文报上。

(首段）Nowadays，in an attempt to avoid using one’s own chopsticks to pick food from the same dishes, a public service advertisement named “public chopsticks” is being broadcast on CCTV everyday.

(尾段）I appeal to everyone to take action right away.

总结：写倡议书记住以下要点

首段：点明现象

中段：措施 、原因(1,2,3--)

尾段：呼吁行动

练习：近日，针对越来越多的学生狂热地追求明星偶像，以至于不顾学业，丧失自我的现象，请写一封倡议书号召大家理智追星。

(首段）Nowadays, a growing number of students are pursuing stars crazily, and many of them are losing themselves in the process.

(尾段）I strongly advocate that sb should do--- / It is strongly advocated that--

I appeal to everyone to take action right away.（call on sb to do也可）

固定句式的熟练记忆，会让自己在碰到类似写作过程中“有所想，有所写，写的对，得高分”，继续努力吧，少年！
