2、系动词be用复数形式are，同时后面的名词用复数形式。(1) 在回答主语是this或that的一般疑问句或特殊疑问句时，在答语中用it代替句中的this或that。当回答主语是these或those的问句时，在答语中用they代替句中的these或those。(2) 在介绍某人时，用this或that，而不用he或she。(3) 打电话时，说自己是谁用This is，问别人是谁用Whos that?3. 如何将单数形式的句子变为复数形式的句子我们在进行句型转换时，常会遇到“将单数形式的句子变为复数形式的句子”这类题。如何将单数形式的句子转换为复数形式的句子呢？(1) 指示代词的变化：this变

4、变化。I, she, he, they在句中作主语，是主格形式。1. 人称代词“I”在任何情况下都要大写，且与am搭配使用。2. 在口语中，如果人称代词孤立地用于不带谓语动词的句子中作主语，习惯上用宾格；如果用主格，就要带谓语动词。 I like playing baseball. 我喜欢打棒球。 Me, too. 我也是。3. 单数人称代词并列作主语时，汉语中通常把“我”排在前面，而英语中的顺序通常是：第二人称第三人称 第一人称，即：you and he; he and I; you and I; he and I。但在承担责任时，要把“我”排在前面。 Are you and she fri

5、ends? 你跟她是朋友吗？4. 单独使用时，he, she与is搭配使用；you与are搭配使用；I与am搭配使用；而任何两个人称代词并列作主语时，均表达复数意义，与are连用。 He and I are cousins. 我跟他是表兄弟。三、连系动词be及其缩略形式1. 连系动词be用在一般现在时中，用于说明人或事物的状态，身份以及年龄等。2. 连系动词be随人称或主语的单复数形式的变化而变化。第一人称单数（I）后用am，第一人称复数（we）后用are；第二人称单复数（you）后都用are；第三人称单数（he, she, it）后用is，第三人 称复数（they）后用are。3. be的现
