Question

______ I was surprised at ______ her positive attitude towards life after losing her legs.

1. A.
   How, is
2. B.
   That, was
3. C.
   What, were
4. D.
   What, was

Answer 1

D
考查名词性从句。What I was surprised at是主语从句，what引导起该主语从句并在句中做at的宾语。第二空用was,因为表语是不可数名词attitude，同时句子又是过去时。句意：让我感到惊讶的是她在失去腿以后对待生活的积极态度。
