新概念英语第一册Lesson19_20

practice
• 请你变换刚才的三个句型，分别改成一般 疑问句以及否定句。
• There is a tie in the box. • There are two shirts on the bed. • There is some water on the desk.
Key point
• 1.不管作主语的名词有多少个，be动词的数只与第一个 名词保持一致。这就是传说中的就近原则。
sit down
stand up
Mother: Are you all right now? Boy: No, we aren’t.
肯定回答：Yes, we are. 否定回答：No, we aren’t. (aren’t = are not) 肯定句：We are all right now.
all right =OK
口诀
• There be句型不一般，主语跟在be后边。 • be可变为is / are, there永远不变化， • 单数主语用is, 复数主语要用are。 • 变疑问，很简单，be须大写来提前； • 变否定，也轻松，be后not记心中； • 肯定句中用some, 否定、疑问any用。 • 时间／地点是状语，句子首尾任你选。
