英語四級選詞填空備考技巧

　　下面是小編整理的，希望對大家有幫助。

　　確定空白處詞性

　　以下情況，空白處為動詞：

　　1 n./pron. vt. n./pron. 前有名後有名，中間謂動

　　2 n./pron. vi.　前名後無名，謂動不及物

　　3 n./pron. vi. adv./prep.前名後介副，謂動不及物

　　4 n./pron. link v./be adj.前名後形容，be動或系動

　　5 to v.　前有to，後原型

　　注意：確定空白處為動詞，還需根據上下文確定正確形式

　　以下情況，空白處為分詞：

　　過去分詞：

　　1has/have/had p.p***完成時態***

　　2be p.p***被動語態***

　　3p.p n.或 n. p.p***過去分詞做形容詞，表示被動或已發生***

　　現在分詞：

　　1be -ing***進行時態***

　　2-ing n.或n.-ing***現在分詞做形容詞，表示主動或正在進行***

　　3prep. –ing***介詞賓語***

　　以下情況，空白處為名詞：

　　***名詞通常做主語或動詞介詞賓語***

　　1a/the n. 前有冠詞

　　2n. V. 空白後為謂語動詞

　　3prep. n. 空白前為介詞，則空白處為名詞或動名詞

　　***注意：根據空白處前的冠詞和上下文判斷所填名詞的單複數;根據空白處後的謂語動詞的形式判斷所填名詞的單複數***

　　以下情況，空白處為形容詞：

　　1adj. n. n. adj. 空白前後是名詞

　　2adv. adj. 空白前是副詞

　　3link v./be adj. be動或系動後考慮形容詞做表語

　　以下情況，空白處為副詞：

　　1adv. v.或 v. adv.副詞修飾動詞，表示程度狀態

　　2adv. adj.副詞可修飾形容詞

　　3adv.從句，有些副詞做句子的狀語，表示轉折因果等邏輯關係

　　確定考點需要積極意義還是消極意義，繼而縮小選擇範圍，節省大量時間。

　　Sample: The classroom ***offers*** opportunities for children to replace angry, violent behaviors with _______ , peaceful ones.

　　***根據語法判斷此處為形容詞，與peaceful有一樣具有積極意義，與前文的angry, violent詞義色彩相反，那麼comprehensive, cooperative, entire應選擇cooperative***

　　介詞後一定是名詞或動名詞做賓語.

　　注意 to ***介詞&動詞不定式***

　　to的短語接動名詞 :abandon oneself to***沉溺於***, adhere to***堅持***, stick to***堅持，信守***, cling to***堅持，忠於***, admit to***承認***, confess to***承認***, contribute to***做貢獻***, feel up to***感覺能勝任***, get down to***開始著手做***, give one’s mind to***專心***, give way to***讓步***, yield to***屈服***, lead to***導致***, look forward to***渴望***, object to***反對***,take to***開始從事，喜歡***, turn to***求助***, succumb to***屈服***, see to***照顧，料理***, get used to, be accustomed to, be addicted to, be committed to, be dedicated to, be devoted to, be opposed to, be reduced to, be subject to***受支配的，常遭受***, submit to***順從，屈服***

　　利用不定冠詞***a/an***判斷考點是否為母音開頭，縮小選擇範圍

　　Sample: Husband and children now do some of these jobs, a ____ that has changed the target market for many products.

　　***scale, potential, gap, extreme, purchase, situation***

　　充分利用詞庫中的近義詞或反義詞

　　***若詞庫中出現一對近義或反義詞，其中一個必定是干擾項.反義詞考查學生對文章語境色彩的辨析，只要辨析考點單詞是積極還是消極意義，就不難排除.近義詞考查考生對詞彙搭配用法的掌握，需要學生牢記近義詞的各種用法及搭配。***

　　Sample：

　　A*** gravely　B*** respect　C*** limited

　　D*** specialize　E*** seriously　F*** promoting

　　G*** involves　H*** relieved　I*** significant

　　J*** magnificent　K*** range　L*** issues

　　M*** result　N*** determining　O*** complicated

　　Today, we take pain______.

　　***此處應用副詞做狀語，考查近義詞辨析.Take sth. seriously為固定搭配***

　　注意一詞多性：詞庫中的詞有的既是名詞又是動詞，有些分詞也可以充當形容詞，確定空白處所需單詞詞性後要全面考慮詞庫中的單詞詞性，不能遺漏。

　　***respect, result, range***
