這些例子搜尋以下關(guān)鍵詞的重要性：否定詞，具體的數(shù)字，限定范圍的詞，具有肯定或否定意義的詞和時間指示詞。其他的需要搜尋的關(guān)鍵詞包括：

Modals e.g. words like must, should, have to (varying degrees of obligation or certainty)

情態(tài)動詞（表示不同程度的義務(wù)和確定性）

Adverbs of frequency e.g. sometimes, always

頻率副詞，如sometimes, always

Words such as most, some, all

諸如most, some, all等限定詞

3. 同義轉(zhuǎn)換能力 (Paraphrasing Ability)

A paraphrase is a restatement of a paragraph, sentence, or word.

我們通過對一道TRUE/YES考題的分析來掌握同義轉(zhuǎn)換能力。

EXAMPLE

The original sentence (文章原句):

“Until recently, criminologists could not afford to analyze DNA evidence for all homicide cases.”

An effective paraphrase of this sentence（題目中的同義轉(zhuǎn)換）:

“Crime labs now can use DNA for all murder cases.”

NOTE: This paraphrase utilizes synonyms to replace key words. Some are very close (DNA vs. DNA evidence and homicide vs. murder), while others take more liberties (criminologists vs. crime labs and could not vs. now can). The essential meaning has been retained, however, despite these significant changes.

通過上述的分析，總結(jié)出以下四種同義詞轉(zhuǎn)換技巧：

replace a Phrase with a Word (or a Word with a Phrase) 單詞詞組轉(zhuǎn)換

Until recently 轉(zhuǎn)換成了now，criminologists轉(zhuǎn)換成了Crime labs

Start the Sentence Differently 句型結(jié)構(gòu)轉(zhuǎn)換

原句采用了Until recently……criminologists could not的結(jié)構(gòu), 而在題目中的運(yùn)用了Crime labs now can……的結(jié)構(gòu)

Replace a Word with a Synonym 同義詞轉(zhuǎn)換

同義詞轉(zhuǎn)換包含了詞匯轉(zhuǎn)換的內(nèi)容，但更注重的是對于單詞本身的替換。

上面例子中最明顯的同義詞替換就是homicide和murder。另外analyze和use的替換也屬于這種情況。

Change Passive into Active Voice/Negative Slant to Positive 主動被動轉(zhuǎn)換/ 否定肯定轉(zhuǎn)換

這種轉(zhuǎn)換方式和句型結(jié)構(gòu)的轉(zhuǎn)換有相似的地方，但更注重表達(dá)方式的理解。如”until recently……could not afford to analyze……” 轉(zhuǎn)換成了”……now can use……”
