名词性从句　 　

[语境中体悟用法]

朗读下面短文，体会、领悟加黑连接词引导的是什么从句，在从句中作什么成分。

What worries my classmate, Mary, a lot these days① is that she puts on too much weight and is frequently ill②.She has some doubts whether she eats too much fast food high in fat or sugar③.Also, with the College Entrance Examination approaching, she becomes more stressful and she couldn't sleep well these days.Maybe this is also the cause that she becomes fatter these days④， she thinks. How she becomes slimmer and healthier⑤ has been her main task. So she wants to consult some experts and gain some instructions. But

where she could get better suggestions and who will give her better advice⑥ also puzzle her. It is her parents' suggestion that she should consult Professor Wang in Zhongshan Hospital⑦.Professor Wang suggests that she keep a balanced diet first⑧. She should eat vegetables and fruit high in fiber, vitamin and protein. What's more, if she wants to lose weight, she had better take regular exercise more than half an hour a day. Mary asked Professor Wang when she should take exercise⑨.Professor Wang advised her to take exercise at 5 o'clock in the afternoon because she will have more time to do sports.Thanks to Professor Wang, Mary has become much healthier now.

④为同位语从句。说明the cause的具体内容。

⑤为主语从句。表示“如何”变得更苗条和更健康，故用how引导，how在从句中作方式状语。

⑥为主语从句。表示去“哪里”咨询、向“谁”咨询，故分别用where, who引导。

⑦为同位语从句。说明suggestion的具体内容，从句内容完整，不缺任何句子成分。

⑨为宾语从句。when在从句中作时间状语。

[集训中明晰考点]

(2)连接词whether表示“是否”，只起连接的作用，不充当句子成分，在部分宾语从句及it作形式主语的主语从句中可以替换成if。

解析：if/whether　分析句子结构可知，“________ you can join in when it's possible”为宾语从句，且从句成分完整，表示“问他们是否你可以加入”，所以填if/whether。

解析：that　分析句子结构可知，该句是一个主从复合句，it作形式主语，真正的主语是设空处引导的从句，且空处在从句中不作任何成分，故填that。

考点2　连接代词

连接代词who, whom, whose, what, which等不但起连接作用，也在从句中作名词或代词所作的成分，如主语、表语、宾语、定语等。如果缺少连接代词，则从句不完整。

解析：what　句意：经过了几千年，他们开始较少地依靠野外猎取或采集的东西，而更多地依靠他们饲养的动物和播种的农作物。分析句子结构可知，______ could be hunted or gathered from the wild作depend on的宾语，且从句中又缺少主语。表示“……的东西”，因此填连接代词what。

解析：which 　空处引导宾语从句并在从句中作主语，表示“哪一个”，应填which。

连接副词how, when, where, why不但起连接作用，且在从句中作状语，表示方式、时间、地点和原因等。

考点4　“疑问词＋­ever”类连接词

1.This actor often has the first two tricks planned before performing，and then goes for ________.

解析：whatever　句意：这个演员时常在表演前就计划好前两个技巧，然后全力以赴。此处作介词for的宾语，表示无范围的选择，故用whatever。此处可视为名词性从句的省略，即．..goes for whatever he wants。

2.My grandmother helped me believe that I could accomplish ________ I put my mind to.

解析：whatever　句意：我的祖母帮助我相信我能完成我下定决心要做的任何事情。这是一个含有宾语从句的复合句，且引导词在从句中作介词to的宾语，表示“无论什么，任何事情”，故用whatever。

3.The gold medal will be awarded to ________ wins the first place in the bicycle race.

解析：whoever　句意：这块金牌将被授予在这场自行车比赛中获得第一名的人。介词to后是宾语从句，从句中缺主语且表示“人”，因此填whoever引导宾语从句并在从句中作主语。
