these students are good.

these students are good.they study English good.找出错误

Answer 1

These students are good.They study English 【well】.
句意：这些学生很优秀,他们的英语学得很好.
good是形容词,一般修饰名词作定语,也可以在句中作表语.well是good的副词修饰,副词才可以修饰动词,所以将good改为well.

We sit 【under】 the trees 【段搭during/at】 lunch time.
句意：中餐的时候我们坐在树下.
under the trees 表示“在树下”,at lunch time 表示“在中餐的时候”,at也可以芦唯用介词during来代握哗拿替.
