◆选择关系代词和关系副词最有效最实用的方法是分析定语从句的句子成分：如果定语从句缺主语或宾语或表语，一般选关系代词；如果从句主语、宾语或表语齐全，一般选关系副词（特殊情况除外）；如果定语从句缺少定语，则只能选关系代 whse，请观察以下句子
1. I will never frget the day _______ I first went t schl.2. I will never frget the day ____________ we spent in Beijing.3. The huse ___________ we visited is being repaired nw.4. The huse _______ Luxun nce lived is being repaired nw.5. I saw a huse ________ windws faced t the suth then.6. D yu knw the girl _________ father is an engineer ?
● 温馨提示:主句是疑问句时,首先要确定定语从先行词,方法是将疑问句恢复成肯定句,然后进行辨别确认, 请观察以下句子a. Is this the factry ______________ we visited last week?※肯定句:This is the factry _________ we visited last week.b. Is this factry _____________ we visited last week?※肯定句:This factry is ___________ we visited last week?c.

◆ 限制性定语从句与非限制性定语从句：用逗号和先行词隔开的定语从句叫非限定性定语从句。● 温馨提示：关系代词和关系副词中, 只有关系代词 that 不能引导非限定性定语从句，请观察以下句子

5. He knws the factry where his father wrks.6. This is the factry, where he wrked yesterday.7. The earth is rund, as is knwn t all.
