You can see the two that you gave me. 4) 先行词中既有人又有物时； e.g. We were deeply impressed by the teachers and schools that we had visited. 5) 主语中已有who和which的； 6) 先行词在主句中做表语或关系代词在从句中做表语时； e.g. It’s book that will help you a lot. My hometown is no long the place that it used to be. 2、 不宜用that的情况 1) 关系代词前有介词时； e.g. This is the room in which Lu Xun lived. 2) 非限定性定语从句中； e.g. He has a daughter, who works in a hospital. 3) 先行词本身是that时； e.g. The clock is that which tells the time 2) 只能用that作为定语从句的关系代词的情况 a) 在不定代词，如：anything, nothing, everything, all, much, few, any, little等作先行词时，只用that，不用which。 All that is needed is a supply of oil. Finally, the thief handed everything that he had stolen to the police. b) 先行词有the only, the very, the just修饰时，只用that。 He is the very man that helped the girl out of the water . c) 先行词为序数词(the last)、数词、形容词最高级时，只用that。.
