Unit 2 第3课时 Grammar Focus (3a－3d)（分层作业）-【一本·初中同步训练】2025-2026学年七年级下册英语（人教版·新教材）安徽专版

第3课时 Gramm 语法精讲 一、祈使句 1.概述 祈使句一般用来表示请求、命令、劝说、号 召、警告等。其肯定式以动词原形开头，否定 式通常在动词原形前加don't。为表示礼貌， 祈使句经常在句首或句末加please.。句末用 please时，前面通常加逗号。 Go along the road and turn left at the first crossing. 沿着这条路走，然后在第一个十字路口左转。 Don't be late for class.上课不要迟到。 2.句式 (1)Do型，即以实义动词原形开头。 Open your book.打开你的书。 (2)Be型，即以系动词be开头。 Be quiet！安静！ (3)Let型，即以动词let开头。 Let him come in!让他进来！ 【注意】Let型的否定句还可以是“Let sb.+ not+动词原形+其他.”。 Don't let him come in.Let him not come in.不要让他进来。 (4)No型，即“No+名词/动名词.”。 No smoking!禁止吸烟！ No photos!禁止拍照！ 二、情态动词(can、have to、must) 1.can的用法 can是常见的情态动词，不能独立作谓语， 其后须接动词原形。它没有人称和数的变化。 can的否定形式为can't/cannot。 (1)can的基本用法 ①表示能力，意为“能；会”。 Lucy can speak English.露西会说英语。 ②表示请求或许可，意为“可以”。 Can you help me with my Chinese? 你能帮助我学中文吗？ ar Focus (3a-3d) ③表示推测，意为“可能”，常用于否定句和疑 问句中。 The T-shirt can't be Amy's.It's too small for her.这件T恤衫不可能是埃米的。这对她来 说太小了。 (2)由can构成的句式结构 主语+can+动词原形+其他 肯定句 He can play the piano.他会弹钢琴。 主语+can't/cannot-+动词原形+其他 否定句 He can't/cannot play the piano. 他不会弹钢琴。 Can+主语+动词原形+其他？ 肯定回答：Yes,主语+can. 一般疑 否定回答：No,主语+can't. 问句及 一Can he play the piano? 其答语 他会弹钢琴吗？ -Yes,he can./No,he can't. 是的，他会。/不，他不会。 特殊 特殊疑问词+can+主语+动词原形+其他？ 疑问句 What can he do?他会做什么？ 2.have to与must的用法 have to与must两者都可表示“必须”，其 后接动词原形。其不同点如下： (1)have to强调因客观需要而不得不做某事， 意为“不得不”。must表示说话人的主观看 法，意为“必须”。 (2)have to可用于不同的时态，有人称和数的 变化。must没有人称和数的变化。 【注意】l.have to的否定形式为don't/ doesn't have to,意为“不必”，相当于needn't; must的否定形式为mustn't,意为“禁止； 不准”。 2.在含有must的一般疑问句中，肯定回答为 “Yes,主语+must.”;否定回答为“No,主语+ needn't/don't have to/.doesn't have to.”。 Unit 2 17 语法精练 I·用括号内所给词的适当形式填空 1.Please listen )to me carefully, children. 2.I must go)now,or I'll miss my train 3. not wear)a hat in the classroom. 4.I can dance but I can)sing. 5.We have to arrive)at school at 7:50 on Monday morning Ⅱ.单项填空 ()1.The little boy is only 6 years old,but he make kites well with his creative mind.
