Unit 6 The Animal Kingdom(句式) 句式精讲精练 句式精讲 1. John and Anthony looked after Christian very well. look after意为“照顾,照看”,相当于take care of。例如: My father is ill, so I have to look after him at home. 我父亲病了,所以我得在家照顾他。 She is old enough to look after herself. 她长大了,能够照顾自己了。 【拓展】 look at=have a look at看 look over检查 look up(在字典等)查找 look for寻找 look forward to期待,盼望 look around环顾 2. Clearly, he could not live with John and Anthony any more, so they took him to Africa. not…any more意为“不再”。not常位于be动词、情态动词或助动词之后,any more常位于句末, 相当于no more。no more常位于句中,放在be动词之后,实义动词之前,两者经常可以互换。 例如: He doesn’t live here any more. = He no more lives here. 他不再住在这里了。 【拓展】 表示“不再”的词还有not…any longer或no longer。二者的区别在于: (1) not…any more = no more,表示数量或程度上的“不再”增加,通常修饰终止性动词。例如: The baby isn’t crying any more. = The baby is no more crying. 这个婴儿不再哭了。 (2) no longer = not…any longer表示时间或距离上的“不再”延长,通常修饰延续性的动词。例如: I can’t stand it any longer. 我对此再也不能忍受下去了。 3. They can keep our homes safe. keep + 名词/ 代词+ 形容词,意为“使……保持某种状态”。例如: Keep the door open, please. 请让门开着。 【拓展】 (1) keep sth.意为“保存某物,保管某物”。例如: How long can I keep the book? 这本书我能借多长时间? (2) keep sb. doing sth. 使(某人)不停做某事。例如: I’m sorry for keeping you waiting for so long. 对不起,让你久等了。 4.... John and Anthony were ...sad to leave him, but they were also happy to see Christian live freely in Africa. (1) 动词不定式短语to leave him和too see Christian live freely in Africa分别用在作表语的形容词sad和happy后作状语,说明产生这种情绪的原因。例如: I’m glad to hear it. 听到这件事我很高兴。 (2) leave(left; left),在此处作及物动词,意为“离开”。例如: He left school three years ago. 三年前他中学毕业了。 【拓展】leave的其他用法: 1) leave作不及物动词,意为“离开”。“leave for+ 地点”意为“动身去某地”。例如: He had to leave at six yesterday. 昨天他必须在六点离开。 He left for Shanghai last night. 昨晚他动身去上海了。 2) leave作及物动词,意为“忘记带,丢下”。“leave sth. + 地点状语”意为“把某物落在某地”。例如: He left her backpack on the bus yesterday. 昨天他把背包落在公交车上了。 5. Can you tell us something about Christian? tell sb. about sth. 意为“告诉某人关于某事”。例如: He told me som
