—So smile at the world and it will smile back.
A. what B. how C. that D. which
【答案】A。解析：句意：我相信世界是你所认为的那样.所以微笑着面对世界世界也会对你微笑。题干空格后面是be 动词后面的表语从句，表语从句中插入了插入语you think;去掉you think发现从句中缺少表语.名词性从句中，what在从句中可以充当表语，因此A为正确答案。

A. what that B. whether that C. that what D. that whether
【答案】C。解析：考查同位语从句。句意：在你的帮助下，毫无疑问，我们的计划是成功的。there is no doubt之后是一个同位语从句，doubt用在否定句中，从句用that引导;______ our plan is meant for是同位语从句中的主语从句，缺少for的宾语，用what引导.故C为正确答案。
10. Those _____ finished doing it put up your hands.
