在漫長的30分鐘四級聽力中，最怕的就是撿了芝麻，丟了西瓜。最重要的信息經常會因為一時疏忽而丟掉分數(shù)。所以，在四級聽力中，一定要抓住以下這七類關鍵詞！
一、轉折性詞匯
學會聽轉折詞匯，如yet,however,though,whereas,unfortunately,unexpectedly,instead,ratherthan,otherthan,tobefrank,franklyspeaking,totellyouthetruth,etc.
二、邏輯類詞匯
表原因：because,becauseof,for,as,dueto,owingto,inthat,nowthat,accordingto；
表結果：therefore,so,asaresult,consequently,eventually;
表遞進：apartfrom,inaddition,furthermore,what'smore,moreover,etc.
三、級詞匯
形容詞和副詞的級最需要關注，如mostimportantly,themostpopular...thebiggestof...
四、事實羅列詞匯
在諸如actually,infact,asamatteroffact,etc.這些詞匯后可能是關鍵的考點
五、序數(shù)詞
如thefirst,firstlyandfinally
六、情態(tài)動詞
如sb.hasgotto,can,could,may,might,need,should,oughtto,etc
七、重要形容詞
表示重要的詞本身就很重要呢，如important,crucial,chief,major,significant,theonly,unique,essential,necessary,vital,etc.
