{01}________ what the situation would be like, they decided to keep silent.
A.Having not known
B.Knowing not
C.Not know
D.Not knowing
解析：本题考查分词作状语表原因．不知道与决定沉默应是同时发生．故用一般式not knowing．
本题选D。
{02}---Oh, it’s you! I ______ you.
--- I’ve just had my hair cut.
A.don’t recognize
B.didn’t recognize
C.haven’t recognized

解析：试题分析：句意：——哦，是你！我刚才没有认出你。  ——我才剪得头发。it’s说明现在认出了你，在现在之前没认出你，所以应是一般过去时。故选B。
考点：考查时态的用法。
