Answer 1

一、主句中缺主语。表语。宾语。时，what可以在从句中做主语。表语。宾语
I hardly understand（understand是及物动词）后面要加sth，所以句子缺宾语，
he has told me（应该是told me ...sth.)缺宾语，所以用what

二、 A。which
主句是完整的句子，从句是定语从句，which you are not sure指代such things

三、B where
主句从句都是完整的句子，所以B where 做地点状语，B where 也可以用in which

四、D .which
这种句子没有连词，所以,most of which hadn't been cleaned for at least a year,是做定语修饰ten windows
PS：如果是He paid the boy 10 for washing ten windows ,and most of __hadn't been cleaned for at least a year,就要用A ,these 或B ,those

五、D .the manager is talking to
作定语，修饰doctor,，the manager is talking to完整的是whom/who the manager is talking to ，whom/who可以省略

六、until
你认为这篇关于UFO的报告怎么样？
很好！许多学生对它很感兴趣，他们一直站到会议结束才离开。

追问

2个为什么不选what

最后一个不是not until才是直到……才吗

Answer 3

1 what引导的宾语从句
2选c as 引导的定语从句 so...... as是固定搭配
3选A
4D
5D
6until 直到

Answer 4

1、由于what引导一个宾语从句，指代内容，不能省略。而that引导宾语从句时不能有实际意义，通常可以省略。
2、选择C as。be sure of后面接宾语，此处没有of，因此不能看做定语从句，只能看作是时间状语从句，译为：不确定的时候不要谈论。
3、选择A that。此处visit是及物动词，后面接宾语。所以，不能用B，况且，C表达的意思和B一样，同时排除。The one不能做关系代词。
4、D。非限制定语从句。
5、D。省略了who或者that的定语从句。
6、until。时态决定。过去时，排除by.固定搭配：in the end;at the end of.但是后者没有until更准确，until表达了时间的延续。
