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
