不定式英语选择题
1.The boy wanted to ride his bicycle in the street,but his mother told him___.
a.not to b.not to do c.not do it d.do not to
为什么不选b
2.She did nothing ___ at the photo.
a.except look b.but to look c.except to look d.but looking
如果没错的话,这里except look是等于but look的,我想知道为什么什么时候用but do 什么时候用but to do.老师说出现do,did,done,does,就用but do,但是我不明白为什么.
（如果解决好,）
