employees who enjoy more leisure time will have fewer mistakes and work more efficiently这一句为什么要加个who？如果没有who的话句子对不对？如果错为什么错？
括号里面的宾语从句忽略that什么意思啊？
追答that 引导的宾语从句通常可以省略，不用who 语法上没有错误，但意思就不对了~
追问嗯？刚才另一位回答的仁兄说不用who语法就错了，说是有2个动词啊，enjoy和have？
追答宾语从句可以省略that，employees enjoy more leisure time that will have fewer mistakes and work more efficiently 等同于employees enjoy more leisure time will have fewer mistakes and work more efficiently ，就是will have fewer mistakes and work more efficiently中 have 和work 的逻辑主语此时不是employees，意思就不对了，要分析准从句，先要熟悉句子成分的划分~
那么这一句哪句是主句哪句是从句啊？
追答who enjoy more leisure time 是从句
employees will have fewer mistakes and work more efficiently 是主句
是因为enjoy和have2个动词吗
追答从句是由引导词引导的句子，这里的引导词就是who，所以由who引导的句子就是从句
追问等于说一个从句和主句可以用2个动词是这样吗？那3个动词呢？
追答一个句子只有一个动词，再加个动词要么变这个动词为分词，要么再套从句。
