1、选词填空选词填空的特点：1) 文章不会太长(约300词)；一般来说第一句是文章主题句并且不设空；一般每隔15-30个词会有一个空；空与空之间有完整意群；2) 方框中词汇难度不高，文章难度要略低于阅读理解难度。选词填空的考点：1) 词汇方面以实词为主，即名词、动词、形容词、副词；2) 语法方面考察词性之间关系和句子结构分析能力；3) 逻辑方面考察上下文联系。结合经典例题精讲A. environmentB. necessarilyC. allowed D. cheatedE. international F. admitted G. hardly H. necessaryI. joy J. com

8、sleeping在“She is sleeping.”中就是动词，而在“sleeping beauty”中就是形容词，答题时以动词为首选进行判断。第二步：抓住中心，略读文章首先要抓住文章首句，迅速找到文章的主题词或主题。和完型填空一样，一般文章第一句不设空格，以便让考生知道本文的相关主题词或主题。建议使用略读的方法，以快速掌握文章大意。第三步：确定空格词性，填词入空首先，根据语法知识确认可以被填入此空的词性，然后按第一步中标注出的词性进行筛选，最后将备选词逐个代入空中细读句意，考虑上下问逻辑关系做出选择。以示例中第一个空为例，空前面的词是has，这时出现两种情况：1. has是及物动词后面可以
9、加宾语，需要填入一个名词。2. has是现在完成时的助动词，后面需要使用过去分词。也就是说名词性的environment, joy, excitement, difficulty和过去分词形式的allowed, admitted, cheated都有可能。但是空后面的是一个介词in而allowed, admitted都是及物动词后面加宾语时不需要介词，所以空中只能从environment, joy, excitement, difficulty四个名词和cheated中选取。根据上下文意思，此空应为“困难”，而且符合句型have difficulty in doing，故选difficulty
10、。然后请在difficulty的K处用笔作个记号，表示已用过了。确认空格处词性的规律： 1.确定空格为名词(1) 如果空格前面为冠词a /an/the、形容词adj.或者及物动词vt.，空格处应填入名词。示例第三空communication(交流)(2) 如果空格前面是介词，空格充当该介词的宾语，需填入一个名词。示例第二空joy(3) 如果空格后面是谓语动词的，且空格前没有句子主语，空格处应填入该动词的主语(名词)。示例第九空environment2.确定空格为动词(1) 如果空格前面已经有名词或代词做主语，后面又有名词或代词作为动词的宾语，且中间无谓语动词，空格处应为及物动词。(2) 如果空
11、格处前面是be动词，后面又无宾语且句意为被动，空格中应填及物动词的过去分词。示例第四空admitted(3) 如果空格前面是名词或代词做主语，后面没有宾语或有一个介词加宾语，且中间无谓语动词，空格处应填不及物动词。示例第六空cheated(4) 如果空格处前面是名词或代词做主语，后面是形容词，空格应填入系动词或be动词。(5) 如果空格处前有不定式标志to，空格处应填入动词原形；另一种情况to是介词，后面应填入动名词。3.确定空格为形容词(1) 如果空格后面为名词的，空格处可能填入形容词。示例第八空necessary(2) 如果空格处前面是副词的，空格处可能填入形容词。(3) 如果空格处前面是
12、系动词或be动词的，空格处可能填入形容词作表语。示例第十空international4.确定空格为副词(1) 如果空格处前面或者后面为动词的，空格处可能填入副词。示例第五空hardly(2) 如果空格处后面是形容词的，空格处可能填入副词。第四步：跳读检查只读有空格的句子，检查句意是否通顺。之后，再通读全文，进行再次检查。 课堂精练I.
