16.d
require 引导的句子要用虚拟语气 should + 动词原形 should 可以省略
17.d
it 在这做形式宾语 后面的that 从句是真正的主语
18.a
before she had time to realize what was happening 她还没有意识到发生了什么事时或者是还没有回过神的时候
19.c
be careless of sb to do sth 是固定搭配 某人做什么事很粗心
so I did 表示我真是这样的 对前面的话表示肯定
20.c
倍数的表示方法
也是固定搭配
倍数+as long/large/big/many as

对于前三题的回答我很赞同，我觉得20题应该选d,句意应该是美国人如今吃的菜比1910年所吃蔬菜的两倍还多。
