3,does he_____(like)it or does he really forget it?
B i think that he really forgets how_____cook it because he has not cooked for a long time.
麻烦一下请详细说一说为什么那么填吧!

答案

1.agreed to come agreed（表过去时态,agree to do sth)
will learn to cook (一般将来时,how to do sth为 做某事的方法）
2.need learnt（助动词do提前,need用原形,a long time ago为过去时标志）
decide（与forgot 对应 时态统一）
3.like（does提前,like原形）
to（同1）
