The children went there to watch the iron tower being ecrected.用be erected 对不,为什么

问题描述:

The children went there to watch the iron tower being ecrected.用be erected 对不,为什么

用be erected不对,因为这里着重强调的是铁塔被立起的整个过程,用being erected更准确。这里也不能用 to be erected。

watch the iron tower to be erected
或者
watch the iron tower being erected
后者更强调动态的信息,强调安装的过程

不对,句意是:孩子们去那儿看那座正在被建造的铁塔.
必须用-ing形式.
