你的思路 在做有关不定式的选择题 时 有不妥 的地方
本题 关键是 看 作表语 的形容词 与后面的不定式 的关系
也就是 不定式是否能反射 to leave her alone is too yong显然说不通 所以 不能用不定式 的主动形式
所以是 she is too young _to be left___alone
答案 是C
如果 仅仅 考虑 被动关系 那么 下面 这道题 你就会 做错
the book is too difficult to read .
这里的不定式 必须用 主动形式 to read 而不能用被动形式 to be read
因为这是 不定式的反射用法 to read the book is too difficult 能说通 .
再如 the box is too heavy to carry
C
选择C答案，换成主动就是leave her alone at home,
Too.....to是太小以至于不能一个人留在家里
正确答案应该是 C
too...to 结构，太... 以至于不能....
太小了以至于不能被单独留在家里
知道这个解构了，再看被动，应该是不定式的被动
C
