解题思路： 固定结构
解题过程：
省略动词不定式符号to后的动词部分的情况
1.一些表示心理活动、情感态度的动词或短语，如expect \want \hope \wish \love \hate \decide \plan \mean \try \would like \be ready \be afraid \be glad等后，动词不定式省略to后面的动词部分，但保留to。例如：
(1)-I 'll be away on a business trip.Would you mind looking after my dog ?
-Not at all .I 'd be g l ad to.
(2)-Will you go with me ?
-Well ,I 'd like to.
(3)-Will you go home tomorrow?
-No.I 'm going to a lecture，or at least I am planning to.
2.不定式作宾语补足语时，省略to后的动词部分，即用to代替整个不定式。例如：
(1)The boy wanted to ride his bicycle in the street?but his mot her told him not to.
(2)You'd better finish the job on time if he ordered you to.
3.在一些情态动词或助动词ought to \have to \used to \be able to后。例如：
(1)-Must I go now?
-No.You don 't have to.
(2)-Are you planning to see your grandfather ?
-No.But I ought to.
此处是省略了they used to live next door,因此不是省略do
