Summary
通常我们可以根据too ... to结构中的不定式是否为及物动词来确定它是否带宾语。

(动词go是不及物动词，其后不直接加宾语)

她太穷了，买不起这么贵的衬衫。
(动词buy是及物动词，其后接宾语such an expensive blouse)
too ... to结构和never一起使用时并不表示否定。
One is never too old to learn. 活到老，学到老。
“to be + too + adjective + to do” 可以用“to do + not + adjective + enough + to do” 替换，在第二种句型中使用的形容词是第一种结构中使用的形容词的反义词，也可以用so---that---替换。
