What’s this B. What’s that 看到近处的一支笔,询问应该用:( )A. What’s this B. What’s that 参考解析:1.答案是 B。解析:“What’s that ” 用于询问离说话者较远的事物。题目中提到看到远处有一个苹果,“that” 指代离说话者较远的东西,所以应该用 “What’s that ” 来询问。而 “What’s this ” 是用来询问离说话者较近的事物。2.答案是 A。解析:“What’s this ” 用于询问离说话者较近的事物。题目中说看到近处的一支笔,“this” 指代离说话者较近的东西,所以要用 “What’s this ” 来询问。“What’s that ” 用于询问远处的事物,不符合题意。2.祈使句例句:解析:“Let” 是一个常用的动词,在祈使句等结构中有特殊的用法和含义,它主要有 “让、允许” 的意思,常用来提出建议、请求或发出指示等,引导的句子往往涉及到一方允许或促使另一方去做某事。牛刀小试单项选择题“Let's ______ a picnic this weekend.”A. have B. has C. having“Let him ______ his homework first.”A. do B. does C. doing参考解析A解析:“Let's” 是 “Let us” 的缩写形式,在 “Let's + 动词原形” 这个结构中,表示 “让我们做某事”。这里的动词要用原形,“have a picnic” 是 “野餐” 的意思,所以应该选 A。“has” 是第三人称单数形式,“having” 是现在分词形式,都不符合 “Let's” 后接动词原形的语法规则。A解析:在 “Let + 宾语(him)+ 动词原形” 的结构中,动词要用原形。“do one's homework” 是 “做作业” 的意思,所以应该选 A。“does” 是第三人称单数形式,“doing” 是现在分词形式,不符合 “Let + 宾语 + 动词原形” 的语法要求。3. “can表示能力”例句:解析:“can” 作为情态动词,在表示能力时,意为 “能、会”,用来描述某人具备做某事的本领或者技能,强调的是一种客观存在的能力情况。其基本结构为 “主语 + can + 动词原形”。牛刀小试单项选择题She ______ sing very well.A. can B. cans C. is can______ you play tennis A. Are B. Do C. Can参考解析A解析:“can” 是情态动词,没有 “cans” 和 “is can” 这样的形式。在 “主语 + can + 动词原形” 这个结构中,表示 “某人能 / 会做某事”,在这里 “She can sing” 意思是 “她会唱歌”,所以应该选 A。2. C解析:根据句子意思 “你______打网球吗?”,这里是在询问对方是否具备打网球的能力。“Are” 用于构成现在进行时或主系表结构的一般疑问句;“Do” 用于一般现在时的一般疑问句,且句子中的谓语动词是实义动词时。而 “Can” 用于询问某人是否具有做某事的能力,“Can you play tennis ” 符合题意,所以选 C。练一练基础题一、从下列单词中选出不同类的一项。( )1.A. our B. us C. let D. sweep( )2.A. classroom B. window C. blackboard D. sweep( )3.A. close B. put away C. floor D. clean( )4.A. chair B. desk C. dirty D. blackboard二、找出下列单词中划线字母发音不同的一项。( )1.A. our B. floor C. door D. blackboard( )2.A. close B. window C. show D. how( )3A. chair B. there C. here D. where( )4.A. sweep B. meet C. see D. let三、英汉翻译Let's clean the classroom and sweep the floor.________________________________________________________Please put away the books and clean the blackboard.________________________________________________________Close the window and keep the classroom clean.________________________________________________________She always cleans the desk and chair after class.________________________________________________________The classroom is dirty.

It's big and bright. But sometimes it gets dirty.” 说明教室一开始是又大又明亮但脏了的状态,A 选项说又小又暗不符合原文描述;C 选项说干净整洁与原文提到脏了相悖;D 选项说太吵闹文中未提及,所以选 B。答案:A解析:文中明确表述 “Lily said, 'I can clean the blackboard. It's so dirty.'”,可以看出是 Lily 想要去擦黑板,所以选 A。答案:C解析:文中提到 “Max stood up and said, 'I'll sweep the floor. There's much dust on it.'”,表明 Max 帮忙打扫教室的方式是扫地,A 选项是 Yang Ling 相关任务;B 选项也与 Yang Ling 的任务相关;D 选项是 Mike 做的事,所以选 C。答案:B解析:文中 “Yang Ling walked to the desks and chairs and said, 'Let's put away the books and clean these desks and chairs.'” 说明 Yang Ling 提出把书放好是因为要清洁书桌和椅子,A 选项说因为书脏了文中未体现;C 选项老师没专门让她因这个原因放书;D 选项说地上书太多也未提及,所以选 B。答案:B解析:原文 “And Mike went to the window and closed it because it was a bit windy outside.” 清晰表明 Mike 关窗户是因为外面有点风,A 选项不喜欢阳光、C 选项想让教室变黑以及 D 选项老师让他这么做都不符合原文意思,所以选 B。 展开更多...... 收起↑ 资源预览
