知识点拨
考点 01 There is / There are ...:There be句型
There is a desk. 有一张课桌。
There are two chairs. 有两把椅子。
▸ There be句型表示“某处有某物”。There is 后接单数名词;There are 后接复数名词。
解析:There be句型用来说明“某处有某物”。名词是单数时用 There is;名词是复数时用 There are。
一、There is + 单数名词
名词是单数可数名词(a desk、a door、a computer)时,用 There is。
例句:There is a computer in our classroom. 我们教室里有一台电脑。
二、There are + 复数名词
名词是复数(two fans、four windows)时,用 There are。
例句:There are four windows in the classroom. 教室里有四扇窗户。
⚠ 易错提醒:There are two chairs.(√) There is two chairs.(✗) two chairs 是复数,用 There are!

Open the window, please. 请打开窗户。
Turn on the fan, please. 请打开风扇。
▸ 想让别人做某事,用“动词原形 + ..., please.”;please 也可以放在句首:Please open the window.
解析:想让别人做某事,直接用动词原形开头,句尾加 please 更有礼貌:Open the door, please.(请开门。)please 也可以放在句首:Please close the window.(请关上窗户。)
一、动词原形 + ..., please.
直接说动作:clean(擦)、open(打开)、close(关上)、turn on(打开)、turn off(关掉)。
例句:Please clean the blackboard. 请擦黑板。

课堂上常用指令句:Stand up, please.(请起立)Sit down, please.(请坐下)Come in, please.(请进)Keep quiet, please.(请保持安静)
