    Let’s ask him to turn it down. 我们让他把收音机音量关小. turn down意思为“把音量关小“.反义词是turn up把音量开大.类似的短语还有:turn on “打开 .turn off “关掉 .其中on, off ,down, up都为副词.因此代词作宾语.必须位于动词之后.副词之前.如: The TV is too noisy. Please turn it down. 电视机太吵了.请把音量关小. Please turn off the lights when you leave home, and turn up the radio. Then nobody dare break in. 当你离开家的时候.请关灯.将收音机开大一点.没人敢闯进来. 关于动词不定式的教学建议 动词不定式是非谓语动词的一种.所谓非谓语动词就是不能做谓语的动词结构.正因为如此.所以他不受主语的人称和数的变化的影响.不必和主语保持一致.没有人称和数的变化.不定式是由to+动词原形构成.这个to只是不定式的一个符号.没有任何实际意义.另外.由于是动词不定式.他自然具有了动词的性质.因此可以带宾语和状语.不定式加上它的宾语或状语构成不定式短语.虽然不定式不能做谓语动词.但是可以作除谓语以外的其它句子成分. 动词不定式极其短语在本单元中出现的几种语法功能: 1) 用作宾语 I’ve begun to learn English. 我已经开始学英语. The old man always forgets what to do. 那位老人总是忘记该做什么. Liu Mei wanted to ask the teacher a question. 刘眉想问老师一个问题. 句中to learn English, what to do, to ask the teacher a question分别作谓语动词begun, forgets, wanted的宾语. 动词不定式作及物动词的宾语.常用的及物动词有begin, want, hope, forget, remember, like, love, need, try, ask, learn, wish, agree, choose, start:等. 2) 用作宾语补足语 Tell the child not to play on the road. 告诉孩子们不要在路上玩. My father told me to turn the radio down. 我父亲告诉我要我把收音机的音量调小些. I often help my mother (to) do housework at home. 我经常在家帮助妈妈做家务事. 句中not to play on the road, to turn the radio down, (to) do housework at home分别作tell, told, help的宾语补足语. 注意:1.作动词ask, like, tell, want等的宾补时.动词不定式要带to.如: 【查看更多】

    One day, my wife and I went shopping. We took the car as we had a lot of things to buy because my brother and his family were going to spend the weekend with us. We stopped the car in front of the shop. An hour later we came back to the car with a lot of things. Then the trouble started. We could not open the car door. “Oh, dear,” said my wife. “What are we going to do?” “Let’s ask that policeman,” I said. The policeman was very kind and glad to help us. Soon he got the door open. Just at that moment an angry man came up and shouted. “What are you doing with my car?” We looked at the number of the car, and our faces turned very red.
