　　2n. V. 空白后为谓语动词

　　3prep. n. 空白前为介词，则空白处为名词或动名词

　　确定考点需要积极意义还是消极意义，继而缩小选择范围，节省大量时间。

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

　　(根据语法判断此处为形容词，与peaceful有一样具有积极意义，与前文的angry, violent词义色彩相反，那么comprehensive, cooperative, entire应选择cooperative)

　　介词后一定是名词或动名词做宾语.

　　注意 to (介词&动词不定式)

　　to的短语接动名词 :abandon oneself to(沉溺于), adhere to(坚持), stick to(坚持，信守), cling to(坚持，忠于), admit to(承认), confess to(承认), contribute to(做贡献), feel up to(感觉能胜任), get down to(开始着手做), give one’s mind to(专心), give way to(让步), yield to(屈服), lead to(导致), look forward to(渴望), object to(反对),take to(开始从事，喜欢), turn to(求助), succumb to(屈服), see to(照顾，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(顺从，屈服)

　　利用不定冠词(a/an)判断考点是否为元音开头，缩小选择范围

　　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)

　　充分利用词库中的近义词或反义词

　　(若词库中出现一对近义或反义词，其中一个必定是干扰项.反义词考查学生对文章语境色彩的辨析，只要辨析考点单词是积极还是消极意义，就不难排除.近义词考查考生对词汇搭配用法的掌握，需要学生牢记近义词的各种用法及搭配。)

　　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______.

　　(此处应用副词做状语，考查近义词辨析.Take sth. seriously为固定搭配)

　　注意一词多性：词库中的词有的既是名词又是动词，有些分词也可以充当形容词，确定空白处所需单词词性后要全面考虑词库中的单词词性，不能遗漏。

　　(respect, result, range)
