Answer 1

They usually _went______(go) fishing when they lived there.

因为后半句用了lived（一般过去时），表明是过去的时间，when前后时态一致

How long ___has____ she ___been___(be) ill?
she，用三单has. ill生病表示状态，用been表示“她生病多久了？”

选择题，选B.
taught一般过去时，时间状语要跟动词一致。
A语法明显错误 C has been taught + ago D has taught + for ten years

We should plant as many trees as possible to protect our environment.
