【精品译文】这位妇女似乎非常喜欢水泵的水,所以她每天都让人把水送到她家。
【句式剖析】
本句是一个复合句。It seemed是主句,that the wman liked...是表语从句,引导的是结果状语从句,在结果状语从句中,had it delivered是“have+宾语+宾语补足语”结构,由于it和deliver有逻辑上的动宾关系,所以用过去分词形式作宾语补足语。
【实例品读】It seems impssible fr yu t cver that lng distance!你似乎不可能走那么远的路!
It seemed hpeful fr him t win the match.他似乎有希望赢得这场比赛。
【看点解读】
句型“It seems＋adj.＋t d sth.”意为“看来/ 似乎是……”。其中it为形式主语，动词不定式为真正的主语。
【经典归纳】
“seem”的句式还有：
(1)“It seems＋adj.＋t d sth.”也可变形为“sb. seems+t d/be ”。
(2)“There seems t be...” 意为“似乎有；好像有……”。

【精品译文】喝这种水的人比喝纯净水或白开水的人更容易得霍乱。
【句式剖析】本句是一个复合句。句中两个wh引导的是定语从句,分别修饰the peple和thse。be likely t d意为“可能做……”。
【实例品读】The price is likely t g dwn because f the cmpetitin.
由于竞争,价格可能会下降。
Yu are likely t suffer frm bad health if yu keep smking.
如果继续吸烟,你的身体健康会受到损害。
【看点解读】
句式“sb/sth be likely t d sth. ”，意为“某人/某物有可能”。
【经典归纳】
likely既可用人也可用物作主语，常用句型是It is likely that...或sb./sth. is likely t...。
pssible和prbable都不能以人作主语，常用句型有It is pssible(fr sb.) t d sth.或It is pssible that...; prbable只能用It is prbable that...。
