【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 woman liked. . . 是表语从句, so. . . that. . . 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。

It seemed hopeful for him to win the match. 他似乎有希望赢得这场比赛。
【看点解读】

【经典归纳】
“seem”的句式还有：
(1)“It seems＋adj. ＋to do sth. . ”也可变形为“sb. seems+to do/be ”。

【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who引导的是定语从句, 分别修饰the people和those。be likely to do意为“可能做……”。
【实例品读】The price is likely to go down because of the competition.
由于竞争, 价格可能会下降。

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 to do 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 to. . .
possible和probable都不能以人作主语，常用句型有It is possible(for sb. ) to do sth. 或It is possible that. . . ; probable只能用It is probable that. . . 。
