P180 B 例句 they/buy a new house/two weeks ago第一问答，使用现在完成时，最后的时间状语不用，把中间部分谓语动词变成过去分词buy--bought--bought，变成Have they bought a new house yet? Yes, they have already bought a new house.第二问答，使用一般过去时态，When提问时间，所以回答使用时间状语When did they buy a new house?They bought a new house two weeks ago.你试着做一下，我等你对答案啊！

forget to do 应该是忘记去做某事FORGET doing 是忘记做过某事TO 是表目的的，就是去做什么，这类词你只要会一个就可以了，我说的应该对吧，好久没看都忘的差不多了，我建议你去买本语法书看看，五年高考三年模拟不错的！
