Unit 1 When was it invented? 第一课时(分层作业) 基础达标 一、用所给单词的正确形式填空 1．Shoes with lights are used for (see) in the dark. 【答案】seeing 【详解】句意：带灯的鞋子是用来在黑暗中看东西的。see“看到”，动词；be used for“被用于……”，其中for是介词，其后接动名词。故填seeing。 2．If I (give) another two minutes, I will do it better. 【答案】am given 【详解】句意：如果再给我两分钟，我会做得更好。根据题干可知，本句是if引导的条件状语从句，主句为一般将来时，从句应用一般现在时表将来；且主句的主语和谓语动词之间是动宾关系，因此应用被动语态，一般现在时的被动语态结构为be+动词的过去分词，主语是I，be动词用am，give的过去分词是given。故填am given。 3．Beijing opera (introduce) to more people around the world during the 2020 Mei Lanfang Art Festival. 【答案】was introduced 【详解】句意：在2020年的梅兰芳艺术节上，京剧被介绍给世界上更多的人。根据句意，主语和动词之间是动宾关系，故应用被动语态；结合时间状语“during the 2020 Mei Lanfang Art Festival”可知，应用一般过去时的被动语态，构成形式为：was/were done；主语“Beijing opera”是第三人称单数形式，故助动词应用was；introduce的过去分词是introduced。故填was introduced。 4．ChatGPT, an AI chatbot, was (develop) by OpenAI and met the public in November, 2022. 【答案】developed 【详解】句意：ChatGPT是由OpenAI开发的人工智能聊天机器人，于2022年11月与公众见面。develop“开发”，动词，和主语之间是被动关系，动词用过去分词，故填developed。 5．How many cities are (mention) in this paragraph? 【答案】mentioned 【详解】句意：在这段多少个城市被提及？根据语境可知句子时态为一般现在时，而主语cities和谓语动词mention之间为逻辑上的动宾关系，应用被动语态，其谓语结构为“be+done”，故填mentioned。 二、完成句子(每空一词) 6．她14岁生日那天，我给她买了一个小提手袋。 A small handbag was her on her 14th birthday by me. 【答案】bought for 【详解】buy sth. for sb.“给某人买某物”，“A small handbag”单数，是动词“buy”的承受者，被动语态，其构成是was/were+过去分词，故填bought for。 7．你说的有道理，还是等到今天晚上比较好。 You . it would be better to wait till this evening. 【答案】 have a point 【详解】根据中英文可知，此处空对应的中文为“有道理”，have a point“有道理”，为动词短语，此处结合句意可知，使用一般现在时，主语为You，使用动词原形。故填have；a；point。 8．The manager gave girls the same chances as boys to apply for jobs.（变为被动句） Girls the same chance as boys to apply for jobs by the manager. 【答案】 were given 【详解】句意：经理给了女孩们和男孩们相同的申请工作的机会。考查主动语态变被动语态。原句是一般过去时，应改为一般过去时的被动语态，其结构为was/were done。主语“girls”是可数名词复数，be动词用were；give的过去分词是given。故填were；given。 9．Where did you take these photos? (变为被动句) Where these photos by you? 【答案】 were taken 【详解】句意：你在哪里拍的这些照片？原句是一般过去时，改为被动语态（was/were+ 过去分词），主语“ these photos ”是复数名词，be动词形式用were。故填were；taken。 10．The terrible earthquake in Chile killed over four hundred people in February.

A．Never mind B．My pleasure C．With pleasure D．It’s a pleasure 【答案】C 【详解】句意：——我可以坐这儿吗？——当然了。 考查情景交际。Never mind没有关系；My pleasure别客气；With pleasure当然了，很愿意；It’s a pleasure别客气。根据“May I sit here?”和选项可知，此处应该表示客气地接受或同意他人的请求。故选C。 12．—I’m afraid the dress is not the right ________ for me. —Well, shall I get you a bigger one or a smaller one? A．color B．size C．style D．material 【答案】B 【详解】句意：——恐怕这件衣服的尺码不适合我。——嗯，那我给你拿一件大一点的还是小一点的？ 考查名词辨析。color颜色；size尺寸；style款式；material材料。根据“shall I get you a bigger one or a smaller one”可知要给他换一件大点的或小点的，说明衣服的尺寸不合适。故选B。 13．Paper ____ first ____about two thousand years ago in China by Cai Lun.
