不要陷入“考試陷阱”,例如:
It was not until 1943 ______ Penicillin was put into clinical use that many fatal diseases were brought under control.
A.that
B.when
C.before
D.after
看到這個題目,考生第一個反應(yīng)是“強(qiáng)調(diào)句”,很快選擇了A,但是再仔細(xì)讀一下,句子后面已經(jīng)有“that”,說明這個題目的考點(diǎn)不在“強(qiáng)調(diào)句”上,而是考“定語從句”的“關(guān)系副詞”when, 故正確答案是B,A稱為“干擾項(xiàng)”。
4.語序:
所謂語序,就是詞(組)或句子排列的順序。
1)形容詞 / 副詞的位置:
形容詞 / 副詞的一般語序是:
形容詞 + 名詞
副詞 + 形容詞或副詞,例如:
Our country is a great country.
He speaks very fast.
當(dāng)有多個形容詞同時修飾一個名詞時,其語序規(guī)則比較復(fù)雜,語法書上有詳細(xì)說明,但不可能都一一記住。只要記住基本要點(diǎn)就可以了,即:越能說明被修飾名詞性質(zhì)的形容詞越靠近那個名詞,例如:“他是中國一位年輕的作家?!?一般的語序?yàn)椋篐e is a young Chinese writer. 有時,這種語序主要是憑語感,沒有多少道理可講。
要特別注意以下情況的語序:
頻度副詞(never, always, often, rarely, seldom等 ):放在be 動詞后面,do動詞前面,例如:
He is always late.(他總是遲到。)
She never comes late.(她從不遲到。)
不定代詞(everything, nothing, something, everybody, nobody, anybody, all, both等):形容詞要放在其后面,例如:
I have something interesting to tell you. (我告訴你件有趣的事。)
enough的位置:enough可以是形容詞,居名詞前,例如:
Let‘s hurry; we don’t have enough time.
(我們趕緊;時間不多了。)
也可以是副詞, 但是要放在被修飾的形容詞或副詞的后面,例如:
They were kind enough to let me in and have a shelter from the heavy rain.
(真感謝他們讓我進(jìn)屋躲過了那場大雨。)
Available, present等形容詞一般放在名詞后面,例如:
They began their experiment based on the data available.
(他們根據(jù)現(xiàn)有資料開始了實(shí)驗(yàn)。)
