小編：杜東飛 393把詞匯量較大除外，句子結(jié)構(gòu)復(fù)雜同樣是新托福閱讀文章的一大障礙。面對(duì)難句，一定要快速的把握其主干與關(guān)鍵，由于考試時(shí)牽涉案的主要是句子的主干和重點(diǎn)，而針對(duì)句子簡(jiǎn)化題尤其是這樣。要把握難句的主干以及關(guān)鍵點(diǎn)，先需要要明白清它們的類型。本文便為大家分析了托福閱讀難句備考類型有哪些的內(nèi)容。
托福閱讀難句備考類型主要包括以下這些：
1.定語(yǔ)(包含后置定語(yǔ)與定語(yǔ)從句)
2.同位語(yǔ)
3.并列結(jié)構(gòu)
4.that引導(dǎo)的各種從句
5.插入結(jié)構(gòu)
6.獨(dú)立主格
7.倒裝句
8.強(qiáng)調(diào)句
9.虛擬語(yǔ)氣
針對(duì)不一樣類型的難句，把握主干的方法也是不相同的。在這里用倒裝句為例，主要有下列情況：
1.方位副詞放在句首
Herein lay the beginning of what ultimately turned from ignorance to denial of the value of nutritional therapies in medicine。
2.介詞放在句首 Among the species of seabirds that use the windswept cliffs of the Atlantic coast of Canada in the summer to mate, lay eggs, and rear their young are common murres, Atlantic puffins, black-legged kittiwakes, and northern gannets。
3. 形容詞放在句首 Implicit in it is an aesthetic principle as well: that the medium has certain qualities of beauty and expressiveness with which sculptors must bring own aesthetic sensibilities into harmony。
4.過(guò)去分詞放在句首
Accustomed though we are to speaking of the films made before 1927 as “silent”， the film has never been, in the full sense of the word, silent。
5.現(xiàn)在分詞放在句首
Missing until recently were fossils clearly intermediate, or transitional, between land mammals and cetaceans。
句子倒裝的目的主要有兩個(gè)：
一是被提前的部分被強(qiáng)調(diào)，如上述的第四句：Accustomed though we are to speaking of the films made before 1927 as “silent”，其中的accustomed按照正常語(yǔ)序應(yīng)該放在are之后：Though we are accustomed to speaking of the films made before 1927 as “silent”。之所以將accustomed提前，是為了強(qiáng)調(diào)它。二是為了句子的平衡，否則將導(dǎo)致頭重腳輕的效果，如上述的一句、第三句和第五句。
以第五句為例，按照正常語(yǔ)序應(yīng)該是：Fossils clearly intermediate, or transitional, between land mammals and cetaceans were missing until recently。但是這種句子結(jié)構(gòu)比較糟糕，因?yàn)橹髡Z(yǔ)及其修飾語(yǔ)過(guò)長(zhǎng)(從句首直到cetaceans)，而謂語(yǔ)部分were missing until recently較短，容易造成頭重腳輕的效果。第五句將missing提前，避免了這一現(xiàn)象。
上述介紹了托福閱讀難句備考類型有哪些的內(nèi)容，為了考試時(shí)能迅速把握托福閱讀文章句子的主干，大家需要較多的閱讀和分析。
