doctor.医生进来了。,There,goes,the bell.铃响了。,2.当表示地点,介词短语,位于句首，且,主语为名词,时，应用完全倒装。如：,On top of the hill,stands,a big pine tree.,山顶上耸立着一棵大松树。,Under the tree,were,some

name,.,直到你告诉我，我才知道她名字。,61/85,3.由连接词 No sooner than，Scarcely when，Hardly when 引发主从复合句，主句应倒装，从句不倒装。如：,No sooner,had,he gone to bed,than,he fell asleep.,他一上床就睡着了。,Hardly had,I got into the classroom,when,it began to rain.,我刚一进教室天就下起雨来。,62/85,5.,All it would do,is,slow down,the rate of change.(line 18),主语有定语从句或本身是主语从句而从句中有实意动词do某种形式时，用作表语不定式能够带to也能够不带to。,All I did,was,(to)give,him a

it,.,1).这是一个含蓄条件句，即虚拟句中有时假设情况不用if条件从句表示，而用介词短语，上下文，或其它方式表示。,这些词或短语主要有,but,without,but for,等，使用方法为当主句与现在或未来事实相反则使用,“would,should,might+动词原形”,结构；若主句与过去事实相反，则使用,“would,should,might+have+过去分词”,结构。比如：,But for,your help,we,would not have finished,the woke,so quickly.,65/85,2).英语中表示倍数句型，,第一个句型:,A+动词+倍数+as+,adj,.,adv,.原级+as+B.,表示“是几倍（长、宽、高、大）”。,这根绳子是那根绳子两倍。,This rope is,twice as long as,that one,.,China is,twenty times as large as,Japan.,中国面积是日本20倍。,66/85,第二种句型:,A+v.+倍数+,adj,.,adv,.比较级+than B.,表示“比（长、宽、高、大）几倍”,Asia is 4 times larger than Europe.,亚洲比欧洲大4倍。,这个房间面积比那个大三倍。,This room is three times bigger
