你好，很高兴能够在这里回答你的问题：

not unill 句型， 直到....才.....

因为hardly已经表示否定，所以不再使用not

选A
翻译为：
我不知道怎么在因特多上使用QQ，尽管大多数人都会使用。

though most of people do相当于though most of people can use QQ on the internet.
尽管大多数人都会在网上用QQ

3
选D
主句为过去，所以从句也要用过去时态

你的体育老师就你在运动会上的跳高成绩是怎么说的？
他说我可以做得更好。

4 the doctor said that he (could)do (nothing)for the old woman

或
the doctor said that he (couldn't)do (anything)for the old woman

两种都可以
