3) ought to have +過去分詞,表示動作按理該發(fā)生了,但實(shí)際上未發(fā)生,譯為“該……”,與should 的完成式含義類似。如:
The porter ought to have called the fire-brigade as soon as he saw the fire in the stock, which went up in smoke .
4) could have +過去分詞,表示過去本來可以做但卻未做,譯為“完全可以……”。這點(diǎn)與ought/should/ have +過去分詞用法相似。如:
What you said is right, but you could have phrased it more tactfully.
5) may/ might have +過去分詞,表示過去可以做但實(shí)際未做,譯為“(那樣)也許會……”。如:
It might have been better to include more punchy statistics and photos of equipment in the introduction to further assist first-time office automation managers.
二.幾個(gè)情態(tài)動詞?嫉木湫停
1).may/might (just) as well “不妨,最好”,與had better相近;

4)下列詞和短語不用比較級形式卻表示比較概念:

5)“比較級+and +比較級”或“more and more/less and less +原級”以及“ever, steadily, daily等副詞+比較級”結(jié)構(gòu)表示“越來越……”的意思,與這類結(jié)構(gòu)搭配的常用動詞有g(shù)row, get ,become等。前面兩種情況更多地出現(xiàn)在進(jìn)行時(shí)態(tài)中,注意的是這三種情況引導(dǎo)的比較級后面都不需要用than.如:
Things are getting worse and worse.
As I spoke to him he became less and less angry.
Her health was becoming daily worse
The road got ever worse until there was no road at all = the road got worse and worse.
6)比較級前面可以用even, still, yet ,all the (more)等修飾語用以加強(qiáng)語氣,表示“更加”的意思。如

D)just as… so… 正如……, ……也……(用倒裝結(jié)構(gòu))
Just as the soil is a part of the earth, the atmosphere.
[A] as it is [B] the same is [C] so is [D] and so is
(答案為C)
2.最高級形式應(yīng)注意的問題:
1)最高級比較范圍用介詞in, over, of, among。
in, (all) over用于在某一范圍內(nèi)的比較,如:in China, all over the world.
of, among用于在同一群體內(nèi)同類事物的比較,如:among the teachers, of the four dresses.
注意:among…相當(dāng)于one of …,不說among all…。這一點(diǎn)考生應(yīng)與漢語表達(dá)區(qū)別開來
如:
all visible lights, red light has the longest and violet the shortest wavelength.
[A] Among [B] Of [C]For [D]To 答案為[B]
2)比較級形式表示最高級意義時(shí),比較對象的范圍應(yīng)用:
any other +單數(shù)名詞
the other +復(fù)數(shù)名詞
the others
anyone/anything else
上述詞是用業(yè)將比較級結(jié)構(gòu)轉(zhuǎn)變成最高級意義的關(guān)鍵詞語,切不可遺漏,尤其是other,否則會造成邏輯混亂的錯(cuò)誤。如不能說:John runs faster than anyone.注意與漢語表達(dá)的不同。
3)most可以用來修飾形容詞或副詞,意思相當(dāng)于very,用法區(qū)分單復(fù)數(shù),但不能用定冠詞the,如:a most interesting book, most expensive restaurants, 要注意與 “the +形容詞最高級+of + 名詞”的結(jié)構(gòu)表示的最高級的區(qū)別,如:
He spoke in the warmest of voices
They have been most kind to me

4.一些表示數(shù)量的短語與名詞連用時(shí)候,謂語動詞的數(shù)取決于名詞的數(shù),名詞是復(fù)數(shù),謂語動詞用復(fù)數(shù),反之就用單數(shù)。這些短語包括:a lot of /lots of; plenty of/heaps of; half of; two-third (three-fourth…) of; eighty(ten, twenty…) percent; part of; rest of ; none of 等等
