Question

几道关于初二英语的题目，各位帮帮忙吧！谢谢！

（1）这是道选择题：John (needn't) practise Chinese more because he speaks Chinese perfectly.
(A) doesn't need (B) need't (C）don't have to (D) needs not to 这道题我知道了选B，但是为什么呢？我们老师要问理由的，谢谢回答一下吧！
（2）这也是道选择题：We (were invited) to attend the meeting last week.
(A)were invited (B) had invited （C） had been invited (D)invited 也是为什么选（A）。
谢谢再告诉最后一道改写句子的题，是要改成反意疑问句：He usually has lunch at home .然后改成了He usually has lunch at home,(doesn't he) 为什么是doesn't he而不是hasn't he呢？感激不尽！谢谢谢谢谢谢！我很急的。谢谢了！！

Answer 1

1.need't 表示need not ，不需要做某事：need not do something
如果A的话：doesn't need to do something，必须有to

2.上周我们被邀请去参加聚会。
were invited，表示过去被邀请，
其他选项不是过去时

3.他通常在加吃午饭，不是吗？
反义疑问句时态和主句对应。主句是一般现在时，doesn't he 是一般现在时，所以对应，hasn't he 是现在完成时的时候采用。
