六年级的英语语法知识点归纳小学六年级英语语法讲解英语语法顺口溜：定语从句中的定从中的关系副词关系副词when/where/why, 从中做状莫懈怠;时间用when原因why,地点where经常在;定语从句中的关系副词有三个：when, where和why，它们在定语从句中分别作时间、地点和原因状语。
when指时间， where指地点，why表原因。
例如： I still remember the day when I first came to Beijing.我仍然记得我初次到北京的那天。
The factory where his father works is in the west of the city.他父亲工作的那个工厂在城市的西郊。
That is the reason why I did the job.那就是我为什么干这个活的原因。
关系副词可替换，介词加上关系代;关系副词可以由介词加上which来替换。
例如：1)This is the house where (in which) I lived two years ago.在这句中，where= in which2) Do you remember the day when (on which) you joined our club在这句中，when= on which3) This is the reason why (for which) he came late.在这句中，reason= for which关系代，关系代，that与who要除外;挑选介词要聪明，必看动词和先行;介词后可用关系代词，但只能用which或whom，不能用that 和who。
那么，这个介词怎么选呢其一，可以看定语从句中的谓语动词;其二，可以看先行词。
例如：1) The pain from which the poor suffered in this area has attractedthe attention of the public.本句中用from 加 which, from与定语从句中的谓语动词搭配，suffer from。
2) English is a useful tool in which I can communicate with foreign friends.本句中用in加which, 和先行词搭配，先行词表语言，因此用in。
聪明反被聪明误，只因乱用关系副;关系副，关系副，定缺主宾它不住;它不住，它不住，关系代词来玩酷;关系副词在定语从句中是做状语的，where做地点状语，when做时间状语，why做原因状语，但要特别注意，如果定语从句中所缺的不是状语，而是主语、宾语或表语，就不要用关系副词，而要用关系代词。
例如：1) I still remember the days _____ we spent together in the mountains last summer.先看定语从句中所缺少的句子成分，spent是及物动词，缺宾语，因此不能填when, 而要用关系代词which或that。
2)This is the house ______ his grandfather once lived in.先看定语从句中所缺少的句子成分，lived in, 明显缺宾语，in是介词，介词后应该有宾语，所以不能填where, 而要用which或that。
3)Is that the reason _______ you explained to the teacher for your being late for school先看定语从句中所缺少的句子成分，explain后应该跟双宾语，缺少一个宾语，因此不能用why, 而要用which或that。
六年级英语语法英语语法顺口溜：定语从句7---As/which/So /such …thatAs/which在句末，若有否定as错;as和 which都可指代前面一句话，请看例句:1)Alice received an invitation from her boss, which came as asurprise.爱丽丝受到了她老板的邀请，这使她感到吃惊。
2)The weather turned out to be very good, which was more than we could expect.天气结果变好了，这是我们没有预料到的。
若有否定as错;3)The result of the experiment was very good, _______ we hadn t expected.A. whenB. thatC. whichD. what【简析】答案是C。
由于非限定性定语从句是否定结构，只能用which引导，不能用as来替代which。
句首只能用as,还有认知猜想词;置于句首时，非限定性定语从句只能用as引导。
例如：As is known to everybody, the moon travels round the earth once every month.众所周知，月亮每月绕地球一周。
与表示认知猜想的词，如know, expect, see, report, 连用时，要用as。
1)As we know, smoking is harmful to one s health.我们知道，吸烟对健康有害。
2)As is expected, his daughter entered a key university.正如人们所期望的那样，他的女儿考入了一所重点大学。
固定结构用as, the same /such/so/as;1) 在the same …as….结构中。
意思是“像……一样的”。
例如：Chongqing is not the same city as we have seen in other places. 重庆和我们在其它地方看过的城市不一样。
注意区分: the same ….that….,请看例句：This is the same pen that I lost. 这正是我所丢的钢笔。
(同一)This is the same pen as I lost. 这支钢笔和我丢的那支一样。
(相似，不是一个)2)在as...as结构中，意思是“像……那样的”。
例如：No period in history has had as many important changes _______ have taken place in the past century. 没有哪个历史阶段像过去的一个世纪这样有如此多的重大变化。
3)在such…as…结构中, 意思是“像……那样的”。
例如：Mathilde had to work hard day and night and bought such a diamond necklace as she had lost to pay back to Jeanne.马帝尔德不得不日日夜夜地干活，来买一个像被她丢掉的那样的钻石项链还给让。
So /such …that宾不离，so/such…as宾要弃;在so/such…that结构中，that后引导的不是定语从句，而是状语从句，从句中必须有宾语;在so/such…as结构中， as后引导的是定语从句，从句中不带宾语。
例如：1)He studies in such a good school that all other students in his village admire him.他在那样好的一所学校学习，以至于村子里其他的学生都很羡慕他。
解析：that后是状语从句，状语从句中有宾语him。
2)He studies in such a good school as all other students in his village admire.他在那样好的一所学校学习，村里的其它学生都很羡慕那所学校。
解析：as后是定语从句,as代替先行词school,在定语从句中做admire的宾语。
