1 强调句 句子的非强调句是Only two people got hurt 强调句结构是IT IS / WAS - -- - THAT / WHO- - - - 把only two people放在was后who之间，把got hurt放在who后面，这样就构成了强调 2 被藏在山洞里 因为hide是及物动词。及物动词后面必须要加宾语，如果没有宾语，hide这个及物动词就必须是被动态形式。所以就用了hidden，而没有用3 those== the genes 前后对比，前面是genes(复数)，后面便是复数，同样的意思，避免重复又如： these books are more interesting than those (==the books on the shelf)又如： The weather of Shanghai is different from that (===the weather ) of Kunming (这里用that因为the weather是单数。)
Dwich需代词借代example，在介词of后跟Ckeep up 词组~good relationships 和。。保持良好关系Bincreasing这句话有动词experienced了，一句话只能一个动词，故排除C，D。后面词组随着。。。接非谓语动词v+ing，意思：随着开创和访问数量的增长CAit was not until 直到。。才，需要倒装排除C，B（that 可去掉意思一样），由was看出只要用过去式即可；D过去的过去：过去完成时it was not until i tided up my bedroom表示一个条件：直到我打理好卧室；the dress appear 做主语，裙子的出现提醒了我它的存在。C．A应该 C．should have been表示假设Dsidered主语Willians，被考虑到是。。Awheretraining centre (with her sister) Axpect of/from 期待 expect for CA需要现在完成时，表示到目前教了几年书。teacher 非延续性动词，用have been doingB过去在教 C。过去一直在教 D really委婉表示否定，从I just do ti for a living我只是为了生计看出并不enjoy Cbefore离发展出有效疗法，还有很多年PS:发现国内的语法题还是挺难的，出国后发现根本说不到有些高级的语法。如有做错请谅解。望有帮助
