1、Skills for Banked Cloze,Contents,题型要求,1,解题步骤,2,Click to add Title,Click to add Title,4,题型要求,四级必考,六级选考一篇文章,十个空格十五个备选(无需改变形式)阅读能力词汇量语法知识,通读全文是用较快速度,一行一行地读,目的是把握至少90% 的文章内容。这大概就用1分钟时间。 选词填空后面的选项词义互不关联,词性也不同,而且还有5个干扰项,一定要先了解文章大意,带着文章脉络去找选项。所以,务必先沉着地把文章读一遍,尤其注意gap 前后的位置,为寻找正确选项打下铺垫。选词填空短文的第一句对全文的内容有概括提示作

2、用,所以一定要认真看懂第一句,而且反复出现的词也是帮助考生掌握文章大致内容的重要线索。,选词填空的解题步骤,第一步:通读全文read through,提醒:通读就是根据首段原则以及首末句原则,迅速抓出文章的主题。判定文章主题对于篇章的整体把握具有很大的积极意义。,第二步:整理选项classify the options,整理选项。大概花费1分钟,即辨别每个单词词性的时间为4秒/词。分别标出15个备选项的词性,比如在名词旁标注n.,在动词旁写上v.,形容词旁标注adj.,副词旁写上adv.等。目前四级考试只考实词(notional words)中的四种:名词n、动词v、形容词adj、副词adv;

3、 (不考代词和数词;也不考虚词(冠词art, 介词prep, 连词conj, 感叹词interj) ),特点:四种实词中,考的最少的是副词adv, 不超过两个空。剩下的三种平均每次有三道题。根据真题,动词一直是考三个。另外三种词性,有两个的,也有四个的。,3. 动词归类要细分为v,v-ed, v-ing。因为一个空可以填动词,但填原形还是过去式还是-ing形式要自己根据语法判断。,标注词性时注意的问题,此外,以-ing, -ed 结尾的词也可能是分词转变而来的形容词,如holding做动词:Shes holding her mothers hand.做形容词:holding company (

4、控股公司);再如acquired做动词:academic skills he acquired.做形容词:a newly acquired jacket (新买的夹克)。,1. 不认识的单词看词缀,2. 认识的单词要注意词性的单一性和多样性 比如:有的词display, concern, challenge做名词 和做动词都很常见.这时两个都要标出来,先标你脑子里第一个出现的词性。,1)动词的确定:动词最容易确定,因为一个句子没有动词就等于没有谓语,是很明显的缺陷。而且动词的关联性、可比性最差,选这个和选那个有天壤之别。,判断原文空缺处所需单词的词性,缩小正确选项范围,如何判断原文空缺处所需单
