Question

He is but too eager to get home.\x05
but 在这里干嘛呢?
它的下还注明了这么一段话我看不懂,Too ..to 结构中,在too之前出现了all,only,but,not等词时,to 后的从句就有肯定意义.（求例句谢谢）

Answer 1

①too……to【【意指“太……而不能” 如本句意思：他太渴望却无法能够回家】】
②这里的but相当于only.这里有几个but这种用法的例句：
　This is but one example of what can happen when things go badly wrong.
　It's going to be difficult.Anyway,we can but try.
　We have relationships of many different sorts -- with our children,our parents,our boss and our friends,to name but a few.
