Unit 1 语法思维导图及专练-【帮课堂】2023-2024学年七年级英语下册同步学与练（人教版）

Unit 1 Can you play the guitar?（语法讲练） 【知识导图】 【要点拓展】 1.be able to和can表示“能力”时可以通用，但can只有一般现在时和一般过去时两种时态；而be able to可以用于多种时态。be able to不能表示允许、可能性。 The police are doing all they can to find her. 警察正在尽一切所能寻找她。 Will you be able to come? 你能来吗？ 2.can表示推测，意为“可能”，一般用于否定句和疑问句中。 —Whose shirt is this? 这是谁的衬衫？ —It can’t be John’s. It’s much too small for him. 它不可能是约翰的。他穿那件太小了。 【奇思巧计】 can的用法要记牢，动词原形来跟梢。 不管人称单复数，现在过去乐逍遥。 can表能力和许可，否定形式表推测。 否定只要接not，疑问赶紧往前跑。 【同步检测】 一、单项选择 1．—Can you go shopping with me, Jack? —Sorry, I ________.
