语法拓展
一、一般现在时中have的用法
一般现在时的谓语动词可以由be动词（前面已学过）或实义动词来充当。今天我们重点学习含有实义动词的一般现在时。（主要介绍have的用法）。
1.定义：一般现在时可以用来表示现在的状况，主语的性格、能力以及经常性或习惯性的动作。
have意为“有”，表示所属关系，有人称和数的变化，其主语一般是人，有时可以是物。
（1）have用于复数名词，第一二人称单、复数或第三人称复数作主语的句子中，has为have的第三人称单数形式，用于不可数名词、可数名词单数或第三人称单数作主语的句子之中。
I have an orange.
Tom has a friend.
（2）have/has作谓语时的句型转换。
①否定句式：主语+don’t/doesn’t+have...
I don’t have an eraser.
He doesn’t have a tennis bat.
②一般疑问句：Do/Does+主语+have...?
肯定答语：Yes,主语+do/does.
否定回答：No,主语+don’t/doesn’t.
—Do you have a bike? —Yes,I do./No,I don’t.
—Does she have a tennis ball? —Yes,she does./No,she doesn’t.
二、并列连词and和but的用法
两词都为并列连词，用来连接两个单词或句子，使其前后的词、短语或句子有顺承、对立或对照性的关系。
（1）but意为“但是；然而”。表示对立或对照性。
He has an apple,but I don’t have one.
（2）and意为“和……；以及……”。表示并列、反复或承接关系。
