首字母填空 <br /> <br /> 给首字母填空类短文题是近几年来各地中考试题经常采用的题型之一,因为它有非常 <br />好的信度和效度,又能拉开考生间的分差、提高区分度。这种题型属于能力测试的范畴,它 <br />考查的范围极广,可以是英语知识的方方面面,还可能涉及其它学科。它要求考生在充分理 <br />解短文的基础上将单词拼写出来,并且单词形式合理,符合语法规范,符合短文需要。这种 <br />试题的首字母已给,所填的就必须是该字母开头的单词。这既是一种限制,又是一种提示。 <br /> 可是这种题型因难度相对较大,考生失分现象比较严重。学生要仔细阅读全文,利用 <br />上下文提供的有关信息,再仔细阅读相关句子,判断所缺单词的句子成分,才能完成练习。 <br />完型填空式中考试卷中最难的题型,最能测量考生实际运用语言的能力。要做好此类题目, <br />考生不但要有较强的语感,善于体会上下文的内在联系,而且要有扎实的语言知识储备和较 <br />大的词汇量。 <br /> 不少同学经过长期艰苦的努力,可能仍达不到理想的训练效果,为了帮助同学们解决 <br />燃眉之急,在平时的教学中我采用了下面的“台阶式”教学法,而且经过试验,我发现这确 <br />实是比较有效的方法之一,对提高学生的解题能力很有帮助。具体做法如下: <br />Step1:掌握七种句子成分与十种词性之间的对应关系。通过对单一成分的分类练习, <br />掌握该句子成分与何种词性相对应。词性正确是答案正确的前提。 <br />(1) 对主语的判断 <br />1. _______ are helpful to students. ( teach ) <br />2. _______ is more important to me than money. ( healthy ) <br />3. Some famous _______ are going to give lectures in our university in August. ( <br />science) <br />4. _______ is my favorite sport. ( fish ) <br />5. _______ stamps is my hobby. ( collect ) <br />Key: 1. Teachers 2. Health 3. scientists 4. Fishing 5. Collecting <br />分析:以上练习中,所填的词均为句子的主语。主语是动作的发出者,词性主要为名词 <br />与代词(1-3);动词不能直接用作主语,必须转化成其对应的名词或动名词(4-5)。此 <br />外,形容词前加 the 以及带连词的句子也可作主语。 <br />例如: <br />The rich are not always happy. 句中 the rich 指“有钱人”,因此可以作主语。 <br />What I wanted was just your help. 句中 What I wanted 是一个带有连词 what 的句子,因此 <br />也可以作主语。 <br />(2) 对谓语的判断 <br /> John was standing on the step of a house. An old woman c________ over to him. <br />“My boy,” she a_____ , “Is your father at home?” “Yes,” a_______ John. The <br />woman b________ ringing the bell. She rang and rang, but there was no answer. At <br />last she t_____ back to John and s______ angrily, “Didn’t you s______ that your <br />father was at home?” “I did”, answered John, “but this i_______ my house.” <br />Key: came asked answered began turned said say isn’t <br />分析:语篇中的所缺词均为谓语动词。谓语是句子所表示的动作,词性只能是动词,而 <br />且在句子中不能缺。当一个主谓结构中同时出现两个或两个以上动词时,还要判断他们之间 <br />的相互关系,对谓语动词或非谓语动词的判断只有在熟练掌握相关知识的基础上,才能作出 <br />正确的判断。平时练习和周练中,我经常让学生做些“用动词的适当形式填空”练习,有助 <br />于对动词形式的判断。 <br />(3) 对宾语的判断 <br />1. Mr. Chen was surprised to see the fast ________ in Shanghai after his long <br />absence from the city. ( develop ) <br />2. The front is in great need of medical _____.( work ) <br />3. Thank you for your _______. ( kind ) <br />4. At last he sold his ______. ( invent ) <br />Key: 1. development 2. wo...
