原句是“What made the story hit close to home was that Bob Collins,the morning show man for WGN,was the pilot of one of the planes and had been killed.”
解释是“这个消息之所以会让人觉得震惊是因为其中一个飞行员死了,而他就是WGN的晨间播音员,鲍勃.克林斯.”
在这里the morning show man for WGN是插入语,解释之前的Bob Collions的身份的,而插入语在句中,一般是要用逗号和句子其他成分隔开的,所有将两个逗号之间的成分去掉也是一个完整的句子,即What made the story hit close to home was that Bob Collins was the pilot of one of the planes and had been killed.
