1、We had not met for 20 years,but I recognized him the moment that I saw him.
这是必应上面的一个句子,我困惑的是 I recognized him 和 the moment that I saw him（定语从句）.的连接看不懂了,我总觉得他们之间应该加个介词.
2、句子+as+句子+as+句子.这种句子间的比较对不对?（貌似《简.爱》中的那句经典台词就是这样）
简爱中的台词：
I should have made it as hard for you to leave me as it is now for me to leave you.
