第一種因果關係

因：because, because of, for, as, since, in that, on account of, with

果：so, so that, therefore, thereby, as a result, hence, thus, consequently, accordingly

因果關係除了傳統意義上的顯性因果表達詞外，隱性的因果同樣是不可忽略的一個重要部分。

隱性因果：

A 導致(因-果)：cause, reason, lead to, give rise to, result in, render, make, let, ask, support, push, stimulate, spark, spur, fuel, produce, be responsible for

如The increased pressures of expanding populations have led to the removal of woody plants so that many cities and towns are surrounded by large areas completely lacking in trees and shrubs.

在這段話中，有lead to, 表示了導致的意思，即結果; 而so that 更進一步表示了後面的結果，所以可以充分判定這段話有因果關係的邏輯。

B 由…而來(果-因)：result from, derive from, originate from, initiate from, stem from, be responsive to, be attributable to

如“The extreme seriousness of desertification results from the vast areas of land and tremendous numbers of people affected, as well as from the great difficulty of reversing or even slowing the process.”

在這段話中，根據result from可以推斷出有因果關係，那如果是解釋句子題時，選項中有因果關係就可以優先考慮。

C 反映，體現(果-因): reflect, present, demonstrate, suggest, imply, show

D 考慮到: given, considering, in view of, thanks to, according to

He succeeded thanks to (in view of) his effort.

E 依賴於: rely on, depend on, resort to,

He resorted to books when he had problems.

F 條件關係：when, once, as soon as, as long as

As soon as he got the money, he would leave the country at once.

G 分詞短語，不定式做狀語:

Failing in the final exam, she cried.

第二種對比轉折關係

A 對比：while, whereas, on the other hand

在解釋句子題，插入句子題中，一旦出現對比關係，學生在掌握的基礎上就能非常快速的判定句間和句內的關係。 While, whereas 前後連接的是平行結構，on the other hand前必定有on one hand, 可以用來把握句間關係。

B 轉折：but, although, despite, in spite of, nevertheless, however

第三種比較關係

A 同級比較: as…as

B 比較級：more…than, -er than, less…than

C 變化：change, alter, vary, modify, revise, increase, decrease, enhance, diminish, develop, progress, advance, improve, retreat, degenerate, continue, remain

D 差異：different, distinguish, separate, same, similar, comparable, compare…to

E 超越：surpass, exceed, excel, over

F 最高級

1)本身有最高級含義：maximum, minimum, peak, outstanding, top

2) 本身程度比較深：amazing, surprising, astonishing, prohibitively high

3) 否定+比較=最高級

No one is more outstanding than him.

從這句​​話中可以看出，否定加比較表示的是一種最高級關係。

第四種否定關係

A 顯性否定：no, not, never, nor, none neither

B 隱形否定：fail to, refuse, remove, miss, reject, absence of, lack of

C 否定前綴：a-, ab-, dis-, il-, im-, in-, non- , un-

否定前綴是詞彙題中經常出的一個考點，把握否定前綴可以幫助考生把握一些生詞，依靠否定前綴對選項進行一個排除。

D 雙重否定：not fail to, not illegal, not uncommon, not unavailable

雙重否定是英文中經常運用的表達方式，由於在平時中文對話中用的很少，​​隨意對雙重否定的把握就顯得特別的重要。
