1. 祈使句的概念 祈使句表示请求、命令等。它的主语是yu(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 D型(以行为动词原形开头),例如: Sit dwn!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 lk 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 D nt (Dn’t)。例如: Dn’t g there, please. 请别去那儿。Dn’t be late fr class! 上课别迟到!Dn’t let him in. 不要让他进来。
1.祈使句句首有时会加上“人称呼语”(后紧接着有一个逗号“,”),目的在于引起话人注意,不是句子的主语,也可以放到句末。
Nancy, ____ (be) careful!Dn’t make any mistakes.
Nancy __ (be) careful and makes n mistakes.Jim, _____________(nt talk) in class.Jim ______________(nt talk) in class.________ (put) up a picture n the wall.________(put) up a pht may take sme time.
dn’t talk
desn’t talk
Putting
2. 有时可以用“Never”(绝不,从不)位于祈使句句首代替“Dn’t/D nt”, 语气更为强烈 。
Never g near the tigers.
Never tell a lie t me!
3. 有时为了强调,在肯定祈使句的动词原形前加上“d”, 表示“一定要/务必….”
D call me when yu arrive there.
D be careful when yu crss the rad.
4.对祈使句的回答 Jack, be careful with matches. __________ Dn’t be afraid f making mistakes. ________________
Ok/Yes, I will.
Ok/N/Srry, I wn’t.
5. 注意常见句型结构: 祈使句, and 主语+will …. 祈使句, r 主语+will…. 1) 刻苦学习,你就会取得好成绩的。 Wrk hard,and yu will get gd grades.= If yu wrk hard, yu will get gd grades. 2) 快点儿,否则我们就迟到了。 Be quick / Hurry up, r yu will be late.=If yu are nt quick/dn’t hurry up, yu will be late.

shuld & had better
had better (’d better),后跟动词原形,没有人称和数的变化。构成:had better d sth. (肯定) had better nt d sth.(否定)你最好立即去医院看病。 Yu’d better g t hspital at nce. 汤姆,你最好今天去那儿。 Tm, yu’d better g there tday. 我们最好不要错过末班公共汽车。We had better nt miss the last bus.
shuld 属情态动词,后跟动词原形,。 肯定形式shuld + V原形; 否定形式shuld nt/shuldn’t +V原形 ▲你应该戒烟。 Yu shuld stp / give up smking. ▲你不应该喝酒后开车。 Yu shuldn’t drive after drinking.
提建议时,可以用had better和shuld,表示“最好”或“应该”做某事,had better的语气比shuld强一些。 安装新灯你前最好读下说明。 Yu had better read the instructin befre putting in a new light. 你应该多锻炼。 Yu shuld exercise mre.=Yu shuld take/d mre exercise.
