1.As to the lost world of Egypt, we know nearly everything ______ to
know.
A. what is B. which is C. it is D. there is
一定不会选B，在定语从句中，如果先行词是不定代词，关系代词只能用that，不能用which。
选A和C的话，从句已经有主语everything,what和it重复了。
选D，不要误以为是there be 句型，在这里there修饰不定代词everything做后置定语，实际上是Know后面接了一个宾语从句everything is to know.关于there的后置定语的类似用法还有：
People there are very friendly.
那里的人都很友好。
2. He himself says he is always punctual in paying his rent, but to my mind_______.
A. he is seldom B. seldom is he
C. he seldom is D. seldom he is
选D
虽然seldom是否定意义的词，但是倒装句的条件之一是“含有否定意义的词放在句首，句子要倒装”，这里都不是放在句首的，正常语序就好。
3. Scarcely______now without some sort of incident involving the old lady.
A. a day passes B. does a day pass
C. passes a day D. day passed
选B，Scarcely表示“几乎不，简直不”，这次是含有否定意义的词放在句首，真的要倒装了。把相应的助动词提前，谓语动词还原。
4. If I see the twin brothers apart I don’t know________.
A. who is who B. who is whom
C. which is which D. what is what
选C，分不清哪个是哪个。
有具体选择范围的时候，用which。
5. Modern transportation facilities make _____traveling through the world in a few weeks.
A.it possible B. possible C.it is possible D.possible of
选A ，这里考察的是“make + it + 宾补+真正宾语 ”的句子结构。
有时候动词的宾语太长，为了保持句子的平衡，就使用it做形式宾语，把真正的宾语放在后面。类似动词的用法还有find,think 等。例如：
He found it impossbile to finish all the work in such short time.
6.________, it was believed, this play was a regular theatrical production established in New York.
A. Until up to B. Not before 1732
C. Up until 1732 D. Not until 1732
选A，until：从某个时点或者状态一直延续 up to：达到某个时点或者状态
如果选择B和D，含有否定意义的词在句首，句子要倒装。这个不是倒装句。
C 没有up until这种表达
7. There comes a time in every man’s life____.
A. then he has to think B. when he has to think
C. therefore he has to think D. about which he has to think
选B
There comesis a time when .......
这差不多是固定用法，意思是有一段。。。样的时光。
when引导的句子修饰time做后置定语。
8. Although Margaret Mead had several assistants during her long investigation of Samoa, the bulk of the research was done by ____ alone.
A. herself B. she C. her D. hers
选A
by oneself 表示“亲自，独自”，固定搭配，也是考察反身代词的用法吧。
希望你能明白
