英语四大特殊结构

四大特殊结构1、强调结构：It is+被强调部分+thatwho +（照抄）剩余部分。通常翻译为“正是”“就是”。It is you who I love. 强调宾语It is I who love you. 强调主语It is when I was a child that I fell in love with you. 强调状语注意：强调结构与it 做形式主语的区别：如果把“It is that”这一部分去掉时，剩下的部分仍然能组成一个完整的句子，那么这个句子就是强调句型。如果去掉以后，不能再组成一个完整的句子，就是it做形式主语的结构。比如：It is you who I love. 去掉“It is that”后，句子还是可以写成：I love you.这个句子绝对是强调句。It is necessary that we should study hard. 去掉“It is that”后，剩下的成分就不能再重新组合成一个新句子，因此这个句子是It做形式主语。It is under the correctwise leadership of Communist Party of China that we live a happy life.在句子强调谓语动词时，通常是在动词前加助动词do。I do love you. He does study hard.2、倒装句型1)so、介词短语、方位副词放在句首时，全部倒装。Tom likes to play football, so do I.In the room are 150 students.注意：表示方位的副词：herethereupdown这类词后面的主语是名词时，句子用倒装。但是如果是主语是代词，句子就不用倒装。比如：Here you are. Here it is.2)only +状语+句子Only by (taking) a training class can we pass TDXL examination.Only in this way can we solve the traffic problems in Beijing city.Only when we grow up do we realize how kind our parents are to us.Only socialism with Chinese characteristics can save China.（更正：这个句子不是倒装句，Only socialism是主语，with Chinese characteristics是介宾短语做socialism的后置定语。can save是谓语动词，China是宾语。）3)否定词、否定短语放在句首时，用部分倒装never、nowhere、by no means、at no time、on no account、under no circumstances、not only but also4)if虚拟条件句中，省略了if时。I would have attended your wedding had I had time yesterday.5)as引导让步状语从句时，必须将表语或状语提前进行倒装（而不是对谓语进行倒装）Ugly as I am, I am gentle.Hard as he studies, Tom makes little progress.6)比较结构（asas; morethan）如果两个句子进行比较时，后面的主语太长的话，就必须把这个句子倒装China invested much less in education than did European countries and the USA.3.比较结构1)原级：常用短语有as asnot soasthe same as。必须对形容词和副词进行比较，而且是同级的比较。The climate in Beijing is quite different from Guangzhou.（错，因为是两地的气候进行比较）The climate in Beijing is quite different from that of Guangzhou.（对）The climate in Beijing is quite different from Guangzhous.He often makes the same mistake as I did two years ago.2)比较级：more+多音节形容词+ than, less+多音节形容词+than, 单音节形容(-er) +than, superior to, inferior to, prior to, senior to ,junior to, the morethe more越，越比较级+than any other+名词单数：比任何其他的都（以比较级的形式表示最高级的含义）Tom studies harder than any other student classmate in our class.Mary is more beautiful than any other student in our class. 3）最高级：the most +adj.adv. in +范围。 the est+ in+范围Jack is the busiest man in our class.Jack is the most responsible man in our class. 形容词的最高级前必须加the，副词的最高级前面加不加the都可以。China is the biggest country in the developing countries.China is the biggest developing country in the world.in 后面是范围：Jack is the best one in our class.of后面跟类别：Jack is the best one of all the classmates.among后面跟类别，但是如果主句不是最高级的时候可以用among. 是最高级的时候只能用of。 Benz is the best one of all the cars. Benz is made in Germany among the cars.4.平行结构搭配要正确，前后要对称not only but also; neither nor; both A and B; from A to B; some, others, and still others Some are from Beijing, others are from Hebei and still others are from the northern part of China.
