人教PEP版三年级上册英语 Unit 1-Unit 3 语法专项易错点练习 be动词、人称代词、物主代词、指示代词、have/has、can与名词单复数 【易错点速览】 (1) be动词用法：I 用 am，you/we/they 用 are，he/she/it 用 is。如：I am a student. / You are my friend. / She is tall. / They are good friends. 注意：be动词要与主语保持一致，不能说 I is / You is。 (2) 人称代词主格：I（我）、you（你/你们）、he（他）、she（她）、it（它）、we（我们）、they（他们/她们/它们）。人称代词主格放在句首作主语。如：He is my brother. / She has a cat. / They play together. (3) 物主代词：my（我的）、your（你的/你们的）、his（他的）、her（她的）、our（我们的）、their（他们的）。物主代词后面接名词。如：This is my book. / Her name is Sarah. / Their family is big. 注意：物主代词和人称代词主格不要混淆，不能说 This is I book. (4) 指示代词：this（这个，近指单数）、that（那个，远指单数）、these（这些，近指复数）、those（那些，远指复数）。如：This is my friend. / That is a dog. / These are my brothers. / Those are cats. 注意：this/that 后接单数名词，these/those 后接复数名词。 (5) have/has 用法：I/you/we/they 用 have，he/she/it 用 has。如：I have a big family. / You have a nice bag. / He has a cat. / She has two brothers. 注意：has 只用于第三人称单数，不能说 I has / They has。 (6) can/can't + 动词原形：can 表示"能够、会"，后接动词原形，没有人称变化。如：I can swim. / She can sing. / They can play football. 否定形式 can't = cannot。如：He can't fly. 一般疑问句把 can 提前：Can you dance? — Yes, I can. / No, I can't. (7) 一般疑问句：be动词直接提前（Are you...? / Is he...?）；can直接提前（Can you...?）；实义动词用 Do/Does 开头，后接动词原形（Do you have...? / Does she have...?）。注意：Does 开头后动词用原形，不能说 Does she has? (8) 名词单复数：一般情况加-s（book→books, cat→cats）；以s/x/ch/sh结尾加-es（box→boxes, watch→watches）；辅音字母+y结尾变y为i加-es（family→families）；不规则变化（man→men, woman→women, child→children, foot→feet, tooth→teeth, mouse→mice）。注意：this/that 后接单数，these/those 后接复数。 一、用 am/is/are 填空 提示：I 用 am，you/we/they 用 are，he/she/it 用 is。 1.
