1B
在针对过去情况时,两者的区别意义明显,不可混用.因为,在过去情况下,主语“潜能”的实施与否,业已成了定局.比较：
1）We could save his life. 我们有办法救活他. （但未必实施）
2）We were able to save his life.我们得以救活他. （付诸实施）
句1）只表示主语有救人的能力,但未必实施；句2）则表示主语非但有救人的能力,而且业已成功实施了.
原句子,我们看到小男孩能举起这个重木头,感到很惊讶,已经看到,已经付诸实施了,所以选B
2C
否定句式中,can't be not able to两者可以通用.第一个空用 can't或者aren't able to
第二个空用 can 所以最终只能选C
希望对你有帮助
