34.【考点】名词性从句
【答案】D
【解析】分析句子结构可知，空白处后面为句子主语“Evidence”的同位语从句，在这一从句中，句意完整，不缺少成分，应该使用“that”作为引导词。因此，正确答案为D选项。
1.同位语从句的功能
同位语从句对名词进一步解释，说明名词的具体内容，一般由that引导。如：
The king’s decision that the prisoner would be set free surprised all the people.
国王作出的这名囚犯释放的决定让人们大吃一惊。
2.同位语在句子中的位置
同位语从句有时可以不紧跟在它所说明的名词后面，而是被别的词隔开。如：
He got the news from Mary that the sports meeting was put off.
他从玛丽那里得知运动会要延期举行。
3.同位语从句与定语从句的区别
1)定语从句中的that既代替先行词，同时在从句中作某个成分（主语或宾语），而同位语从句中的that是连词，只起连接主句与从句的作用，不充当句中任何成分。
2)定语从句是形容词性的，其功能是修饰先行词，对先行词加以限定，描述它的性质或特征；同位语从句是名词性的，其功能是对名词进行补充说明。如：
The news that he told me is that Tom would go abroad next year.
他告诉我的消息是汤姆明年将出国。（第一个that引导的从句是定语从句，that在从句中作宾语）
The news that Tom would go abroad is told by him.
汤姆将出国的消息是他讲的。（同位语从句，that在句中不作任何成分）
(2011·天津)Modern science has given clear evidence ____________smoking can lead to many diseases.
A. what
B. which
C. that
D. where）]
点拨. C。题意：抽烟会导致多种疾病，对此现代科学已经给出了明确的证据。本题考查名词性从句(同位语从句)。evidence后的从句说明的是其具体内容，从句中不缺少句子成分，故用that引导同位语从句。 其他三项引导同位语从句都要在从句中作成分。
【难度】一般
【2017安徽卷】27.The limits of a person’s intelligence,generally speaking, are fixed at birth, but
he reaches these limits will depend on his environment.
A. where
B. whether
C.
that
D.
why
首先把插入语generally speaking删掉，选择B.本题考查名词性从句，but whether he reaches these limits 【作为句子主语】will depend on his environment.
24. It is by no means clear
the president can do to end the strike.
A. how
B. which
C. that
D. what
【答案 【解析What作do的宾语。句意：总统采取什么行动结束这次罢工一点也不清楚。
【考点定位】考查主语从句的连接词。
【2017山东卷】25. It doesn’t matter ________ you pay by cash or credit card in this store.
A. how
B. whether
C. what
D. why
25.【答案解析it是形式主语，后面whether...or…引导的主语从句是真正的主语，whether...or…意为：是…还是…都行。句意：在这个商店中用现金或信用卡支付都可以。

【2017福建卷】35. We promise
attends the party a chance to have a photo taken with the movie star.
A. who B. whom
C. whoever
D. whomever
【考点】本句考查连词的辨析
【答案】C
【解析】首先本句考查的关键短语是promise sb sth“向某人承诺某事“本句指的是向参加聚会的人提供一个和电影明星合影的机会，不定式做chance的定语，然后就是参加聚会的任何人whoever=anyone who，这样句子就很清晰了，所以划分句子成分非常关键，以前考察whoever都是做状语，而本题考查的是作promise的宾语，挺新颖的。
