大學英語四級真題選詞填空解析—性別影響大腦功能

　　【答案】

　　26. [E] challenges

　　27. [J] searched

　　28. [D] categorizing

　　29. [K] similarities

　　30. [L] slightly

　　31. [G] percentage

　　32. [O] traditional

　　33. [ I ] regardless

　　34. [H] proving

　　35. [M] suggests

　　【解析】

　　26. 根據(jù)簡單句的基本句型嘗試，此空格處應(yīng)填入謂語動詞，再根據(jù)時態(tài)和主謂一致原則，此處可填入的備選項為challenges和suggests或tastes，再根據(jù)前后文語境鎖定答案為challenges，這里的challenge是動詞，表“懷疑”。

　　27. 根據(jù)主謂賓的常識以及時態(tài)要求將答案縮小在searched和applied之間，再看空格后面的搭配為for, search for 意思為尋找符合語境;倘若選applied，apply for的意思是申請，與與語境明顯不符合。綜上，故答案為searched。

　　28. 根據(jù)介詞后面需要搭配名詞或動名詞的原則，確認該空格應(yīng)在名詞性質(zhì)的備選項中記性選擇，在根據(jù)前后文語義應(yīng)該填入 categorizing， categorize A as B or C，把A分為B或C;categorize brains as “male”or“female” ，把電腦分為男性或女性。

　　29. 根據(jù)句法知識和詞性搭配，該空格應(yīng)該填入名詞詞性，再根據(jù)空格前的邏輯詞while表對比這一用法，確定while從句與主句是對比關(guān)系，主句中有difference一詞，故將答案鎖定為 similarities。

　　30. 根據(jù)詞性搭配原則，此處應(yīng)該填入副詞故而在slightly和briefly之間進行選擇，再根據(jù)語義將答案確定為slightly。

　　31. 根據(jù)詞性搭配和small一詞的用法，將答案鎖定為percentage，a small percentage of 表示一小部分。

　　32. 根據(jù)詞性搭配嘗試此處應(yīng)該填入形容詞，再根據(jù)前文語義將答案確定為traditional。

　　33. 此題主要考察單詞的固定搭配，regardless of 表示無論，無論從語法還是語義均符合要求，故而選regardless。

　　34. 根據(jù)原文，此處從語法方面考慮需要填一個非謂語動詞，再根據(jù)前文語義故而選擇 providing.

　　35. 根據(jù)簡單句基本句型和時態(tài)及主謂一致此處應(yīng)該填第三人稱的動詞，再根據(jù)語義，只有suggests符合。
