why
1.reason,consideration,explanation等词后面可以接以why引导的从句。例如:
- This is the reason why I did not go.
- There are many considerations why this work should be done.
- Now I have given sufficient explanation why the work should be done at once.
2.在以why开首的疑问句里的do you往往被省去。例如:
- Why spend such a lot of money?
- Why not go there with them?
- Why not apologize and ask his pardon?
