Unit 5 How can we make art?
专题02 语法提升·易错题专项训练
高频易错点03 现在进行时 be + doing
高频易错点01 句型 make art with + 材料 介词 with 混用
高频易错点02 a picture of + 事物 所有格结构混淆
高频易错点、易错点提示、小练笔、答题点拨
易错精讲
句型 make art with + 材料 介词 with 混用高频易错点01
学生分不清 with(用工具 / 材料)、by(靠方式)、use(动词 “使用”)的词性,经常写成
make art by leaves / make art use clay。
易错点提示
1.with + 材料 / 工具(介词短语,表 “用某物创作”,放在句末)
例句:We can make art with leaves. 我们能用树叶做美术作品。
2.use + 材料(动词,作谓语,句中要有主语) 例句:We use leaves to make art.
3.by + 动作 / 方式(后接动名词 doing) 例句:We make art by cutting paper.
小练笔
一、改错,划出错误并改正
1.I make art by clay. ____________
2.They make pictures use leaves. ____________
2、 同义句转换
We can make art with paper. = We can ______ paper ______ make art.
点拨
一、1.by → with;
解析:clay 黏土是材料,表 “用材料” 介词用 with;by 后只能加动作(doing)。
2.use → to use / 句前加 We;解析:句子已有谓语 make,不能再直接跟动词 use;两种改法:They make pictures to use leaves / They use leaves to make pictures。
二、转换题答案:use;to
解析:use sth. to do sth. = make art with sth. 是本单元同义替换必考搭配。
a picture of + 事物 所有格结构混淆高频易错点02
学生分不清 of 无生命所属格,习惯用名词所有格 ’s,或直接名词堆砌,
混淆 “…… 的画作” 表达。
易错点提示
1. a picture of + 物品 / 动物:一幅描绘…… 的画(本单元核心句型)
例句:Here is a picture of a tiger. 这是一幅老虎的画。
2. 错误区分:
✖ the bird’s picture(鸟拥有的画,逻辑不通)
✖ a bird picture(中式英语,教材不认可)
✔ a picture of a bird(标准课本句式)
小练笔
一、汉译英
1.这是一幅兔子的剪纸。________________________
2.我能做一幅花朵的树叶贴画。________________________
二、选词 of / ’s
1.This is a photo ______ a cat. It is not the cat ______ photo.
点拨
一、
翻译 1:Here is a paper-cut of a rabbit.
翻译 2:I can make a leaf picture of flowers.
填空:of;’s
解析:
of 用来表示画作、照片、剪纸描绘的对象;
’s 表示物品归某人 / 某物所有,the cat’s photo = 属于小猫的照片,和 “拍小猫的照片
a photo of a cat” 语义完全不同,是考试高频辨析坑。
高频易错点03
现在进行时 be + doing
1.现在进行时忘记加 be 动词 am/is/are;
2.重读闭音节双写尾字母错误:make→makeing;
3.名词单复数:paper-cut 表泛指要变 paper-cuts,学生常漏 s。
易错点提示
1. 现在进行结构:主语 + am/is/are + 动词 ing(表 “正在做美术创作”)
make → making(不双写,元音 + 辅音 + 不发音 e 结尾,去 e 加 ing)
paint → painting(直接加 ing) cut → cutting(重读闭音节,双写 t 加 ing)
2.paper-cut 复合名词:单数 a paper-cut;复数 paper-cuts
小练笔
一、改错
1.She makeing a paper-cut of a monkey. ____________
2.They paint circles now. ____________
3.I am making two paper-cut. ____________
二、按要求改写句子
Xiaotian is making a tiger paper-cut.(改为一般疑问句并否定回答)
___________________________________________________________
点拨
1. makeing → is making;
解析:缺少 be 动词 is;make 变 ing 是去 e+ing,正确形式 making。
2. paint → are painting;
解析:now 是现在进行时标志词,主语 they 搭配 are,动词变 painting。
3. paper-cut → paper-cuts;
解析:two 后面复合名词变复数,paper-cut 复数只变后面名词。
改写句答案: —Is Xiaotian making a tiger paper-cut? —No, he isn’t.
解析:现在进行时变疑问直接把 be 动词提前;否定回答结构:No, 主语 + be not.

参考答案
一、Read and write(用所给单词正确形式填空)
1.painting
解析:句首 Are 提示现在进行时,paint 直接加 ing,paint→painting。
2. making
解析:Is 是 be 动词,make 以不发音 e 结尾,去 e 加 ing,make→making。
3. are
解析:主语 students 是复数,对应 be 动词用 are。
4. using
解析:现在进行时,use 去 e 加 ing,use→using。
5. cutting
解析:cut 是重读闭音节(辅 + 元 + 辅结尾),双写末尾 t 再加 ing,cut→cutting。
二、 Think and choose(单项选择)
1.A
解析:后半句 painting 是动词 ing 形式,现在进行时疑问句句首用 be 动词;主语 you 搭配 Are。Do 后接动词原形,排除 C。
2.B
解析:Is 为 be 动词,后接动词 ing 构成现在进行时,选 making。
3.C
解析:主语 students 是复数,be 动词用 are;am 只跟 I,is 搭配单数主语。
4. B
解析:后半句 he isn’t 表否定,问句否定回答用 No。
5. C
解析:现在进行时用 cutting;cuting 拼写错误,cut 要双写 t。
6. A
解析:助动词 Does 提前,后面谓语动词还原为原形 paint。
7.B
解析:making 是 ing 形式,现在进行时;主语 she 单数,be 动词用 Is。
8.A
解析:情态动词 can’t 后必须接动词原形 use。
9. A
解析:现在进行时一般疑问句,问句用 Are you,肯定回答固定搭配 Yes, I am。
10. B
解析:问句以 Is he 开头,肯定回答用 Yes, he is。
