英語資源模擬試題名詞性從句

1.________ caused the accident is still a complete mystery.
    A.What B.That C.How D.Where
    答案　A
    解析　主語從句中缺少主語，而能在主語從句中既充當(dāng)主語又起引導(dǎo)作用的只有what。
    2.I just wonder ________ that makes him so excited.
    A.why it does B.what he does
    C.how it is D.what it is
    答案　D
    解析　wonder后面的賓語從句本是“what makes him so excited”，但what需要被強(qiáng)調(diào)，故用強(qiáng)調(diào)句型。
    3.Water，which seems so simple and common，is ________ makes life possible.
    A.what B.that
    C.which D.how
    答案　A
    解析　考查名詞性從句的連接詞。句意為：看似簡單平常的水是使生命出現(xiàn)成為可能的東西。what引導(dǎo)表語從句并在句中作主語。
    4.I’d like to work with ________ is honest and easy to get on with.
    A.who B.whoever
    C.whomever D.no matter who
    答案　B
    解析　所填詞在賓語從句中作主語。who表達(dá)的意思不對，也不符合句子結(jié)構(gòu);whomever不能在句中作主語;no matter who不能引導(dǎo)名詞性從句。
    5.When you are reading，make a note of ________ you think is of great importance.
    A.which B.that
    C.what D.when
    答案　C
    解析　賓語從句中you think是插入語，從句中缺少主語，which意思不對，故選what。
    6.Mr.Smith asked the boy a question________he could go to the concert with him.
    A.whether B.that
    C.what D.if
    答案　A
    解析　考查同位語從句。if不能引導(dǎo)同位語從句;句中缺少疑問詞“是否”，故選A項。句意為：史密斯先生問了男孩一個問題，問他是否能和他一起去音樂會。
