本单元语法——主语从句
1. ________young people see and hear in the media helps them to figure out how the world works.
a. which          b. that
c. what          d. how
解析：选c。考查主语从句。句意：年轻人通过媒体听到的和看到的事情帮助他们了解周围的世界是如何运转的。“young people see and hear in the media”中动词see和hear缺少宾语，因此空白处应填what。
2. (XX年郑州一中月考)________ you don’t like him is none of my business.
a. what             b. if
c. that             d. whether
解析：选c。考查名词性从句。that 引导主语从句，在从句中不作成分；what引导主语从句时充当句中成分；if不能引导主语从句；whether引导的主语从句应是肯定句。由语意可知c项正确。
3. (XX年安徽皖南八校联考)—mary looks down today. what is up?
—well，________ happened between mary and me is none of your business.
a. wherever         b. whoever
c. whatever         d. no matter what
解析：选c。whatever引导主语从句，在从句中作主语。

a. how; that            b. that；which
c. what；which         d. what；that
解析：选a。how在句中引导主语从句；that 引导定语从句，修饰限定词question。句意：药物是如何作用于人体的，这个问题并不是每个人都能完全理解的。
5. ________obama was elected president of the usa is a big success for the blacks in america.
a. 不填            b. that
c. what            d. as
解析：选b。考查复合句。句意：奥巴马当选为美国总统对美国黑人而言是一个巨大的成功。that obama was elected president of the usa 是主语从句，that在从句中没有实义，本身不作句子成分。
