at the beginning of term,we went plant trees around the mountain of town .went 是go的过去式,那么 plant为什么不加ed.

问题描述:

at the beginning of term,we went plant trees around the mountain of town .
went 是go的过去式,那么 plant为什么不加ed.

句子有语病,plant要改为planting,term和town前面要加定冠词the,即At the beginning of the term,we went planting trees around the mountain of the town.
