英语四级十五选十技巧.ppt

1、大学英语四级15选10答题技巧,Word Selection,15选10是大英四级改革后阅读的新题型，有些同学做这 题时会盲目地“试答案”，这不仅会使正确率下降，还会影响答题时间。其实，做这种题时还是有很多 规律可循的。一般将备选分类是最有效的方法，可以按词性划分为名词、动词、形容词和副词。同样，平均到这些类别中的词汇也减少到了3、4个，这样通过上下 文判别空缺单词的词性来有的放矢地选择答案，作对的几率就会明显上升。,对于15选10的题型，解题步骤有四步： 第一步：通读全文， 特别是每个段落的首末句，迅速抓住文章的主题和中心。 第二步：对所给出的备选单词进行词性分类 第三步：根据上下文意思进行

2、填空 (结合样题详细讲解) 第四步：检查核对。 解决15选10题型的五大绝招： 1) 词性判断 2) 常用搭配 3) 内在逻辑 4) 感情色彩 5) 语法常识,第一步是每位学生都要去做的，就是把15个单词通过后缀进行词性分类，但是通常我的习惯是遇到动词进行二次分类：确定时态，确定单三还是非单三；遇到名词 确定单数还是复数；我一直认为单词不认识不应该成为学生放弃选词填空的原因，在做第一步之前我先把4级历年真题选词填空中出现频率最高的后缀全部列举出 来： 名词后缀：tion/sion/ness/ment/er/or/ist/ism 形容词后缀：able/al/ant/ent/tive/sive/o

3、us/less/ed/ing 动词后缀:ate/lize/ing/ed 副词后缀：ly/ward/wise,如何确定词性？,答题技巧一：确定空白处词性,以下情况，空白处为动词： 1 n./pron. Vt. n./pron. 前有名后有名，中间谓动 2 n./pron. Vi.前名后无名，谓动不及物 3 n./pron. Vi. adv./prep.前名后介副，谓动不及物 4 n./pron. link v./be adj.前名后形容，be动或系动 5 to v.前有to，后原型 注意：确定空白处为动词，还需根据上下文确定正确形式,以下情况，空白处为分词：,过去分词： has/have/had

4、 p.p（完成时态） be p.p（被动语态） p.p n.或 n. p.p（过去分词做形容词，表示被动或已发生） 现在分词： be -ing（进行时态） -ing n.或n.-ing（现在分词做形容词，表示主动或正在进行） prep. ing（介词宾语）,以下情况，空白处为名词：,（名词通常做主语或动词介词宾语） a/the n. 前有冠词 n. V. 空白后为谓语动词 prep. n. 空白前为介词，则空白处为名词或动名词 （注意：根据空白处前的冠词和上下文判断所填名词的单复数；根据空白处后的谓语动词的形式判断所填名词的单复数）,以下情况，空白处为形容词：,adj. n. n. adj.

5、空白前后是名词 adv. adj. 空白前是副词 link v.be adj. be动或系动后考虑形容词做表语,以下情况，空白处为副词：,adv. v.或 v. adv.副词修饰动词，表示程度状态 adv. adj.副词可修饰形容词 adv.从句，有些副词做句子的状语，表示转折因果等逻辑关系,答题技巧二：,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 one

6、s. （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),答题技巧三：,后一定是名词或动名词做宾语 注意 to （介词介词&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

7、觉能胜任）, get down to（开始着手做）, give ones 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 t

8、o, be reduced to, be subject to（受支配的，常遭受）, submit to（顺从，屈服）,答题技巧四：,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: After an _ six-month search, first lady Laura Bush announced Sunday that Comferford was chosen from hundreds applicants to head the executive kitchen. (extensive, expansive, executive,) extensiv

9、e为正确答案，,答题技巧五：,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

10、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）,答题技巧六：,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),As an Alaskan fisherman. Timothy June, 54, used to think that he was safe from industrial pollutants (污染

11、物)at his home in Haines-a town with a population of 2,400 people and 4,000 eagles, with 8 million acres of protected wild land nearby.
