2016届高三英语二轮随堂训练课件：专题1 单项填空 1.8名词性从句

　　A. whatever B. whenever C. wherever D. however 【解析】选A。句意: 有些人相信以前发生过或现在正在发生的任何事情将来都会重复发生。believe后面是宾语从句, 宾语从句中缺少主语, 只能选择连接代词。 5. (2016·四川高考)________you said at the meeting describes a bright future for the company.

　　A. When B. How

　　C. What D. That 【解析】选C。句意: 你在会议上所说的描述了公司的美好未来。分析句子结构可知在主语从句中缺少宾语, 故选择C项。【解题技巧】 1. 主语从句中几组易混连接词。 (1)what与that引导主语从句时的区别。 what引导主语从句作主语、宾语、表语或定语, 有意义。 that引导主语从句不作句子成分, 无意义。例如:

　　What you said yesterday is right.

　　That English is important is an undoubted fact.

　　(2)whether与if。主语从句若含有“是否”意义, 且放于句首时, 其引导词常用whether。 Whether he will be able to come tomorrow remains a question. (=It remains a question whether he will be able to come tomorrow. ) (3)“疑问词+ever”引导的名词性从句。 whatever和whichever在名词性从句中作主语、定语、宾语或表语; whoever作主语、宾语。 Whoever(=Anyone who)breaks the law should be punished.

　　2. 形式主语it引导的句式。 ①It+be+形容词(necessary/right/likely/unlikely/wrong/important /certain等)+that从句。 ②It+be+名词(短语)(a pity/a shame/no wonder等)+that从句。 ③It+be+过去分词(said/told/reported/decided等)+that从句。 ④It+特殊动词(seems/appears/happens/matters) + that从句。 ⑤It doesn’t matter/makes no difference等+连接代词/连接副词/连接词引导的主语从句。 3. 主语从句的注意事项。 (1)要分清引导主语从句的三类连词: ①从属连词that不充当句子成分, 本身无意义, 仅起引导从句的作用; ②连接代词who, whom, what, which, whoever, whatever, whichever有意义, 在从句中作主语、宾语、表语、定语; ③连接副词where, when, how, why有意义, 在从句中作状语。 (2)看主语从句里缺少什么成分就补什么成分, 如不缺少成分用that, whether, if; 缺少主语、宾语、表语, 常用what, who, which, whom等; 缺少地点状语用where, 缺少时间状语用when, 缺少原因状语用why, 缺少方式状语用how等, 即要看从句的意思是否完整, 根据“缺什么补什么, 什么都不缺用that”的原则选用连词。考点2　宾语从句【典例】1.
