第一个问题:
1. used to do sth. “过去总做某事”(现在不做了)只用于过去时态。
e.g. He used to get up early.
2. be used to (doing) sth. 表“习惯于做某事”,可用于现在、过去、将来的多种时态,be可以用become, get等来代替,此处to是介词。
3.try to do 表示“努力做某事”;Try doing表示“尝试做某事”。例如:
He tried washing her hair with a new shampoo.
他试着用一种新的香波洗头发。
She didn”t try to do it.
她不肯努力去干
please try to finish this work in twenty miniutes.
请尽量在20分钟完成这项工作。
why didn't you try walking to go to school?
为什么不试着走路去学校呢?
要点:try to do sth.表示"试图干……",强调付出努力,但不一定成功;
try doing表示"尝试干、干……试试",含有"看结果如何"之意。

划线部分;
如果要对划线部分提问,具体看划线部分的内容,是关于人的还是物的,是关于事情还是地点的.
比如说the girl on the bike is Lucy
如果划线的部分是TOM,那么提问就是Who is(the girl) on the bike?
对on the bike提问的话,就是Where is Lucy?
be used to do 是指习惯于,适应于
used to do是指过去常常做,而现在不做了
