之前练习的考察情
况进一步选择讲解
该语法项的重难点。Giving instructions1. 祈使句的概念
祈使句表示请求、命令等。它的主语是you(听话人),通常不说出。祈使句肯定结构中的谓语动词一律用动词原形。祈使句末用惊叹号或句号,句子用降调。
2. 祈使句的结构
1) 祈使句的肯定结构
① Do型(以行为动词原形开头),例如: Sit?down!?坐下!? Stand?up!?起立! ② Be型(以be开头),例如: Be?quiet!?安静!
Be?careful!小心!
③ Let型(以let开头),例如: Let?me?try. 让我试试看。 Let’s?look?at?the?map. 让我们看看地图。
● let’s是let?us的简略式。● 表示请求、劝告的祈使句还常常在句前或句末加上please,?构成句式:Please …或 …, please.?以使语气更加缓和或客气。例如: Please?stand?up. 或
Stand?up, please. 请站起来。 Please?have?a?rest. 或
Have?a?rest, please. 请休息一下。 2) 祈使句的否定结构,一律在肯定结构前加?Do?not?(Don’t)。例如: Don’t?go?there, please. 请别去那儿。
Don’t?be?late?for?class! 上课别迟到!
Don’t?let?him?in.?不要让他进来。
注意:Let’s型祈使句,其否定式也可用 Let’s?not …,例如: Let’s?not?have?rest. 咱们别休息了。 Let’s?not?sit?here!?我们不要坐在这儿! should & had better当我们给他人提建议时,可以用had better和should,表示“最好”或“应该”做某事, had better的语气比should强一些。
You had better refrigerate the beer before drinking it.
喝啤酒前你最好先把它冷冻一下。
You should exercise more.
你应该多锻炼。had better (常简略为’d better),是一固定词组,后面必须跟动词原形,没有人称和数的变化。构成:had better do sth. 句型。
You’d better go to hospital at once.
你最好立即去医院看病。 Tom, you’d better go there today.
汤姆,你最好今天去那儿。
had better 的否定式是将not直接放在had better的后面。
You had better not miss the last bus.
你最好不要错过末班公共汽车。 should 后面也要跟动词原形,且没有人称和数的变化。
You should stop smoking.
你应该戒烟。
should 的否定式是should not/shouldn’t。
You shouldn’t drink and drive.
你不应该喝酒后开车。1. 当我们向他人发出命令、提出要求或建
议时,常使用祈使句。其主语通常不明
确表示出来。其否定形式是在动词原形
前加do not/don’t。为了表示客气和礼
貌,可以加上please。
2. 当我们给他人提建议时,可以用had
better和should,表示“最好”或“应该”做
某事。否定形式是had better not和
should not/shouldn’t。Reflection请点击I. 单项选择。1. The TV is too loud. Please _______. A. turn it down?? B. to turn it down??
