l hate when people talk with their mouths full.1 it 2that 3 this 4 them
答
l hate 【it】when people talk with their mouths full. 1 it 2that 3 this 4 them
句意：我不喜欢人们说话时嘴里塞满食物。
考点：it的用法。
相关知识链接：英语中规定，象like,dislike,hate,love，appreciate 等这类【表示好恶情感的词】，后面不能直接跟when,if等从句作宾语【因为，它们本身实际是状语从句】，因此，连接时，必须先加上it，【指代从句所述具体内容或事实】。例如：
I would appreciate【 it 】if you could come over to help me.
