The organizer being absent 答案与简析：1．（1）B (2) C  前者as usual作状语，意为“象往常一样”；后者是(as early) as I usually got up 的省略式，在句中作比较状语。2．（1）B (2) C  前者用which引导非限定性定语从句；后者用that引导非限定性同位语从句。注意which不能引导同位语从句。3．（1）B (2) C  两句看上去很相似，但第（1）句空格前是形容词serious作定语，故应填入名词；而第（2）句空格前是副词seriously，作状语，修饰谓语got injured。4．（1）C（2）D  在(1)句中all是先行词，that 引导定语从句；（2）句中all作tell的宾语，what引导主语从句，all后的部分作tell的直接宾语，引导词that已省。5．（1）A（2）D  (1)是“had better do”结构，(2)是“It is + adj. + to do”结构。切莫混淆。6．（1）A（2）B  can’t help (to) do“不能帮助做……”；can’t help doing “禁不住做……”。7.（1）C（2）A  be used to doing“习惯于做……”；be used to do “被用来做……”。8.（1）C（2）D  前者是同位语从句，说明前面名词的内容；后者是定语从句，强调性质或特征。9.（1）A（2）D  It was / will be+段时间+before…意为“多久后才……”；It is +段时间+since …“自从（做）……以来已有多久了”。10.（1）C（2）A  前者是强调句，后者不是。因为 midnight 不能在改为“非强调句”时充当句子成分，即不能说A terrible flood struck the village midnight（midnight前缺介词at）。11．（1）D（2）C  引导宾语从句时，介词后用whether, 但宾语从句是否定式时用if 引导。12．（1）C（2）A  前者是副词修饰系表结构is to listen，作状语；后者用形容词simple作表语，to- 不定式短语作逻辑主语。13．（1）D（2）C  suggest 在(1)句中作“预示”讲（此时主语通常是非人称名词）；在(2)句作“建议”，此时其宾语从句的谓语动词用“should + V.原形”，should可省。14．（1）D（2）A  how 在（1）句中作表语；what是代词，在句（2）作介词like 的宾语。15．（1）D（2）B  前者是“名词+分词短语”构成的独立主格结构，作状语；后者是“名词所有格+动名词短语”格成的动名词复合结构，作主语（作主语时动名词的逻辑主语只能用所有格，不能改用普通格）。
