文档介绍：09高考英语易错题：名词性从句考点
    典型陷阱题分析
    1. She was so angry and spoke so fast that none of us understood _______ he said meant.
    A. that                     B. what
    C. that that                D. what what
    「陷阱」，认为这样两个“引导词”叠用的情况不太可能。在A和B两个选项中，选项A肯定不行，因为它引导宾语从句时不能充当句子成分，所以便选择了B.
    「分析」正确答案选 用作动词 meant 的宾语，第二个what 用作动词 said 的宾语，即在 none of us understood what what he said meant 中，none of us understood 为主句，what what he said meant 为宾语从句，而在此宾语从句中又包括有 what he said 这样一个主语从句。
    2. After _______ had happened he could not continue to work there.
    A. which                   B. how
    C. what                    D. having
    「陷阱」可能误选A.
「分析」最佳答案选 ，是因为认为介词后应接关系代词 which，但实际上，若填关系代词，其前没有先行词，这根据不是一个定语从句。另外，由于 had happened 缺主语，所以B和D也不能选。
  3.“Is ______ you want to say？” asked the teacher.
    A. this                   B. that
    C. all that               D. that all
    「陷阱」根据中文字面意思误选A或B.
    「分析」最佳答案选 ，那么转换成陈述句即为：This is you want to say. / That is you want to say. 显然句中的两个谓语动词 is与want相冲突。选D组成的句子是 Is that all you want to say？ 其中的that 为句子主语，all 为表语，you want to say 为定语从句，用以修饰all.
    4. “When ______ leave for Japan？” “When ______ leave for Japan is kept secret.”
    A. they will， will they         B. will they， they will
    C. they will， they will         D. will they， will they
    「陷阱」可能误选D，认为 when 后应用疑问句词序。
