10、ks hard.三、宾语从句一)引导词地挑选结构中欢迎下载精品学习资源宾语从句地引导词除that 只起连接作用外,其他地都有各自详细地意义.因此我们在挑选引导词时,要把句型结构、句意及习惯搭配结合起来,做全盘考虑.请看下面地例句: Youll have to decide car well use, yours or mine Youll have to decide car well use, the old one or the new one Youll have to decide well use the new car for Youll have to decide well u
11、se the new car A whichB whatC whoseD whether再如: I still rememberthis used to be a small village 另外,要特殊留意:动词或动词短语check,make sure 等作确定句地谓语时,全句在汉语意义上虽有 “是否 ”之意,但后面常用that 作引导词 .如:Checkeverything is in order , please 请核对一下是否一切正常.Make surethe door is locked before you leave the lab在离开试验室前,务必弄清门是否锁上了 .二) t
