【分析】
本题为英语句型转换题,需根据不同句式的改写规则解题:1-2题考查一般现在时主动句转被动语态,需遵循“be+过去分词”结构,结合主语单复数确定be动词形式;3题考查含be动词的否定句改写,直接在be动词后加not;4题考查特殊疑问句,对物提问用what,需提前be动词;5题考查含be动词的一般疑问句改写,直接提前be动词。
【解析】
1. 原句为一般现在时主动句,主语stamps是复数,被动语态be动词用are,use的过去分词为used,故填are used。
2. 原句主语a recorder是单数,被动语态be动词用is,use的过去分词为used;by后接人称代词宾格,we的宾格是us,故填is used; us。
3. 原句含be动词is,变否定句时在be动词后加not,缩写为isn't,过去分词为cleaned,故填isn't; cleaned。
4. 画线部分为物(wood),用疑问词what提问,原句含be动词is,变疑问句时将is提前,后面接made,故填What is; made。
5. 原句含be动词is,变一般疑问句时将is提前,后面接过去分词taken,故填Is; taken。

答案

3. is made in 4. was made by

解析

【分析】本题考查英语中“be made”相关短语的用法,需结合句子主语的数、时态以及汉语提示,选择正确的短语搭配。不同短语含义不同:be made of用于能看出原材料的制成品;be made from用于看不出原材料的制成品;be made in后接制造地点;be made by后接制作者,同时要注意主谓一致和时态的匹配。
【解析】1. 句子主语“the model plane”为单数,木头是可直接看出的原材料,对应短语“be made of”,时态为一般现在时,故填is made of;2. 葡萄酒由葡萄酿成,原材料无法直接看出,对应短语“be made from”,主语wine为不可数名词,时态为一般现在时,故填is made from;3. 句子表达“在上海制造”,对应短语“be made in”,按要求填写is made in;4. 句子有过去时间状语“last night”,表达“由姐姐制作”,对应短语“be made by”,时态为一般过去时,故填was made by。
【答案】1. is made of 2. is made from 3. is made in 4. was made by
【知识点】be made短语用法;被动语态
【点评】本题为英语基础题型,考查核心短语搭配,难度较低,学生牢记不同be made短语的用法,结合句子提示即可完成解答,适合初中英语基础练习。
