The company building the canals to transport coals need others to help them.这里的build为什么用 that build

The company building the canals to transport coals need others to help them.
The company that build the canals to transport coals need others to help them.
这两句意思是一样的
第一句是非谓语的形式 与company是主动关系 所以是ing
第二句是定语从句的形式 先行词company 引导词that

满意请点击右上方【选为满意回答】按钮那问个比较宽泛的问题~那这个 非谓语 和 定语从句具体该怎么用呢？只是表达的一种方式而已 如果是在考试当中 变换着用 两者兼顾是最好的
你的问题是具体怎么用 如果要例子的话再追问我 好吗The teacher that strike the students are critisied by educational insititute.定语从句
The teacher strikingthe students are critisied by educational insititute.非谓语
请问这样对吗？对的 定语从句不需要多讲了 非谓语判断清主被动关系即可
