throwing

to be thrown

考查非谓语动词。句意：阳光炽白炫目，在地上投下浓重的阴影。主语The sunlight和throw是主动关系，因此要用现在分词表主动，此处是现在分词短语作状语。故选A项。

introduce

introduced

introducing

am introduced

考查过去分词和省略。句意：当我被介绍给别人时，我通常会说：“很高兴认识你”。根据句子结构可知，本句是when引导的时间状语从句，原句when I am introduced to someone,这里当从句主语与主句主语一致时，并且从句的谓语动词有be这时从句的主语与be同时省略，所以空格处introduced。故选B项。

so have I

so I have

neither have I

neither I have

肯定的陈述句后，跟so+主语+谓语，表示强调：确实…，其主语与前陈述句的主语相同；肯定的陈述句后，跟so+谓语+主语，表示…也…，其主语与前陈述句的主语不同．根据times have changed，可知对另一个"我"说时代也已经变了，用倒装句，本句是现在完成时，含有助动词have，主语为I，在这里还用助动词have完成，故选A．

Only then_______ how much damage had been caused.

she realized

she had realized

had she realized

“only＋状语”位于句首，整个句子用不完全倒装．此外，由then可确定用过去时态．

考查强调句。句意：袁女士，你承诺过的！噢，我确实如此。但是是你先失言的。A和B是一类回答，C和D是一类回答。当别人说他自己怎么样，而你有跟他同样的情况时，用AB这样的形式回答。当别人说你怎么样，而你自己也确实是他说的那样时，用CD回答。至于用be动词还是do要根据具体语句定，谓语是be时就用be的相应形式，谓语是实意动词时就用do的相应形式。根据句意，故选D。
