中考英语知识点：定语从句重点和注意事项

　　e.g.: God helps those who help themselves. 自助者天助之。　　重点提醒: whom在定语从句中作介词的宾语，且介词提到whom前面时，不能用who代替：e.g.: The person to who you just talked is Deep.(错误)　　应该为to whom　　或者可以这样表达：The person who/whom you just talked to is Deep. （正确）　　在现代英语中，定语从句中作宾语的关系代词whom可以用who代替，但who不用于介词之后。在非限定性定语从句中，whom不可用who代替。　　iv.Whose引导的定语从句　　Whose可以指人也可以指物，在定语从句中作定语。　　e.g.: Do you know the girl whose Japanese is excellent?　　I’d like a room whose window looks out over the sea.　　重点提升：有时“whose+名词”可用“限定词+名词+of which/whom”或者“of which/whom+限定词+名词”来替代。　　e.g.: He lives in a house whose windows face south.　　=== He lives in a house whose windows face south.　　=== He lives in a house the windows of which face south.　　另：whose+名词引导定语从句时，名词前不能再接限定词，只有转换为“限定词+名词+of which/whom”或“of which/whom+限定词+名词”时，名词前面可以有限定词。
