非限制性定语从句的特点
例：Davis wanted t visit Dr Yuan’s new farm, where the seawater rice was grwn.
从句和主句用逗号隔开。
从句与先行词的关系不十分密切，只是对修饰词作进一步说明，去掉之后并不影响整句意思。

限制性和非限制性定语从句的区别
1. 限制性定语从句一般是紧跟先行词之后，不用逗号隔开； 非限制性定语从句用逗号和主句隔开。例：This is the city where he used t live. I returned t my hmetwn, where I spent my childhd.
Davis wanted t visit the farm where the seawater rice was grwn.戴维斯想参观种植海水稻的农场。Davis wanted t visit Dr Yuan’s new farm, where the seawater rice was grwn.戴维斯想参观袁博士的新农场， 那里种了海水稻。
2. 限制性定语从句对被修饰词有限定的作用，不能去掉，否则句意不完整； 非限制性定语从句对先行词进行附加说明，去掉也不影响意思完整。
（不能省略，否则句意不完整）
3. 限制性定语从句中先行词是名词、代词或名词短语；非限制性定语从句中的先行词还可以是整个句子。例：Jhnsn’ s father bught him a new bike, which made the by excited fr a lng time.
4. 限制性定语从句的引导词是所有的关系代词和关系副词；非限制定语从句中不能使用that和why;另外，前者引导词可省略，后者不可以省略。例： The man (whm) yu are waiting fr has gne hme. The man, whm yu are waiting fr, has gne hme.
5. 限制性定语从句常翻译成“的+先行词”；而非限制定语从句和主句是并列关系，翻译成“先行词+定语从句”。
例： Davis wanted t visit the farm where the seawater rice was grwn. 戴维斯想参观种植海水稻的农场。 Davis wanted t visit Dr. Yuan’s new farm, where the seawater rice was grwn. 戴维斯想参观袁博士的新农场，那里种了海水稻。
1. After the flding, peple were suffering in that area, _____ urgently needed clean water, medicine and shelter t survive.
解析：非限制性定语从句中缺主语，先行词是peple，所以用关系代词wh引导，不能用that。
2. The by thught the earth is bigger than the sun, _____ is nt right.
解析：非限制性定语从句中先行词是整个句子，关系代词用which。
