1.Have you lived in GZ for a long time?
yes,since I( )this company
A.had joined B.joined 为什么不用A?不是有since吗?
答：因为since后面从句人时态用一般过去时,表示自从某件事情发生以来（至今为止）,主句用现在完成时.如果是至过去某个时间为止,则主句用过去完成时.
析：我估计你老师的话没有听全,或没有真正理“since与完成时连用”,老师说的是如有since从句,则主句用完成时.不是说since 从句的谓语用完成时态.
译：你在广州生活了很久了吗?
是的.自从我加入这个公司以来（就一直生活在广州）.
2.一个句子：because of the high prices the local shopkeepers( )
A.asking B.asked
为什么不用A?不是because of吗
答：这不是一个句子,而是一个短语：because of sth.+定语从句.
这个sth=the high prices,
这个定语从句省略了引导词that或which,因为它在从句中作asked的宾语.
the high prices (which/that) the local shopkeepers asked 当地店主所索要的高价.
从句还原就是：the local shopkeepers asked high prices.
评：初中题,因学生词汇量及出题者本身的问题,题句不是很好,有问题.这个asked high prices就不地道,且有词法错误.不深究了.
3.Her books,( )Devil's Kiss and Love on Midsummer's Night ,are very popular among kids
A.such as B.as for C.because of D.instead of
答案是A 为什么是such as ,such as后面不是加词组吗?后面是句子啊!
答：Her books,such as A and B,are very popular among kids.
译：她的书,如《Devil's Kiss》和《Love on Midsummer's Night》,很受少年的欢迎.
析：A=Devil's Kiss
B=Love on MIdsummer's Night
是两本书的名字.英语中没有书名号,用大写+斜体表示.你如果注意大小写及标点的话,就能看出句子的主要结构.
追问再问个问题 how to do it
为什么一定要有个it how to do不行吗
答：因为do是个及物动词,需要一个it来作它的宾语,如：I don't know how to do it.我不知道如何做这件事.
注意：I don't know what to do.=I don't know what I should do.do的宾语在前面,是what.
再问： 如果是where呢？where to go to 还是where to go where to do 还是where to do it
再答： where to go. go 是不及物动词。 where to do it. where 同how是副词。 建议：追问只限于原题。最好一题一贴吧。 有问题另开一贴。不赏分也行。别问个没完。
