雅思閱讀中重要的句子層級結構
雅思閱讀中有很多句型結構關系，尤其在如此長篇專業(yè)性又強的文章內容中，分清楚句子結構，看清表達關系，對快速找準出題點，提高雅思閱讀速度很有幫助。
? ?? ?1. 表轉折：
but, however, yet, in fact, on the other hand;
A, but B: 否定A而肯定B，則A，B兩部分內容是相反的。
例如：Computerized data storage and electronic mail were to have heralded the paper less office. But, contrary to expectations, paper consumption throughout the world shows no sign of abating .
解釋：paper less 表示負向，則but后no sign of abating 表示正向，所以abating是表示負向的詞。
總結：此種方法有利于在不認識單詞的前提下讀懂句子意思，很有幫助，但一定要練習，而且要敏感。
練習：The marginal costs of generating electricity from nuclear energy may be tiny, but , as the technology now stands, huge and uncertain costs are involved in building the power stations, dealing with spent fuel, and decommissioning.
2. 表讓步：
(1)although：although A, B:盡管有A，B還是出現(xiàn)了(A，B互不影響)若A是正，那B就是負的。
例如：Although the world regards Asia as the focus of an economic and industrial miracle, without adequate supplies of food, Lampe says, chaos could easily result in many countries.
解釋：miracle奇跡，表正向,則but后的chaos是一個表負向的詞。
(2)while：五個含義：
A. although：雖然，盡管
B. as long as：只要
C. whereas, but：表轉折
?。寒敗?。。的時候
E. n. 表一段時間
例如：While ducks offer many advantages over hens, they must be given greater quality of food, especially if regular eggs are desired.
解釋：原文在本段之前講鴨子的好，在本段之后講它的不好。
(3)Albeit：盡管，雖然
例如：Albeit true but not now.
3. 表并列：A and B
A...and B...
(1) 并列雙方性質相同;
(2) 當A、B都比較復雜時，應該從最后一項找起，根據(jù)B的形式到前文找到A
例如：The modern city consists of monstrous edifices and of dark, narrow streets full of petrol fumes and toxic gases, torn by the noise of the taxicabs, lorries and buses, and thronged ceaselessly by great crowds.
解釋：此句話中共有四個and ,第一個and 并列of 結構，第二個and 并列fumes和toxic,第三個and并列taxicabs, lorries 和buses, 第四個and并列full of …, torn by… 和thronged…
4 表遞進：沒有轉折的意思，后項承接上文。
A furthermore B
A moreover B
A besides B
A為正向，B 仍為正向。
5 表順序或過程：
(1) first, then, next, later on, finally
