关注生活中的“祈使句”

祈使句小结
1.定义:用于表达命令、请求、劝告、警告、禁止等 的句子叫做祈使句,祈使句最常用于表达命令,因此 又叫做命令句。 祈使句因对象(即主语)是第二人称,所以通常都省 略。祈使句的动词都为一般现在时,句末则使用句号 或感叹号来表示结束。
例:Go and wash your hands. (去洗你的手。—命令) Be quiet, please.(Please be quiet.) (请安静。——请求) Be kind to our sister. (对姊妹要和善。——劝告)

Watch your steps. (走路小心。——警告) Look out!Danger! 小心!危险!——强烈警告 Keep off the grass. (勿践草坪。——禁止) No parking. (禁止停车。——禁止)
祈使句也常把主语“You”表达出来,使对方听起来觉得柔和 些,例如: You go and tell him, Tom. (Tom, 去告诉他。)
2、相关口令 祈使句无主语, 主语you常省去; 动词原形谓语当, 句首加don't否定变; 朗读应当用降调, 句末常标感叹号。

3、表现形式 ——●肯定结构: Do型——动词原形开头
即:动词原形(+宾语)+其它成分。 如:Please have a seat here. 请这边坐。
有的祈使句在意思明确的情况下,动词可省略。 如:This way, please. =Go this way, please. 请这边走! Be型——动词Be开头
即:Be + 表语(名词或形容词)+其它成分)。 如:Be a good boy! 要做一个好孩子! Let型——动词Let开头。
即:Let + 宾语 + 动词原形 + 其它成分)。 如:Let me help you. 让我来帮你。

3、表现形式 ——●否定结构: Do型和Be型的否定式都是在句首加don't构成。
如:Don't forget me! 不要忘记我! Don't be late for school! 上学不要迟到! Let型的否定式有两种: ①“Don‘t + let + 宾语 + 动词原形 + 其它成分” ②“Let + 宾语 + not + 动词原形 + 其它成分”。 如:Don't let him go. Let him not go. 别让他走。 No开头——用来表示禁止性的祈使句。 如:No smoking! 禁止吸烟! No fishing! 禁止钓鱼!

练习: 将下列汉语翻译成英语。 1. 请照看好您的包。 _P_l_e_a_s_e_l_o_o_k_a_f_te_r__y_o_u_r.bag. 2. 让我们去学校吧! _L_e_t_'s__g_o__to__s_c_h_o_o_l_. __! 3. 亲爱的,高兴点儿! _B_e__g_la_d_,_d_e_a_r________! 4. 不要把书放这儿。D_o__n_'t_p_u_t_t_h_e__b_o_o_k_h__e_re. . 5. 不要让猫进来。 __D_o_n_'_t_le_t__th_e__c_a_t_c_o_m_.e in
