Are those (any) pencil-boxes?在把单数句子变为复数句子时，指示代词需要作相应的变化：thisthese, thatthese。第1、2小题即是如此。3. They are (some) good boys. 4. Are they (any) rulers?5. We are English teachers.在把单数句子变为复数句子时，人称代词需要作相应的变化：主格：Iwe, youyou, he/she/itthey宾格：meus, youyou, him/her/itthem。第3、4、5小题即是如此。6. These are our (my) new books.7. Those blue erasers are ours.在把单数句子变为复数句子时，物主代词需要作相应的变化：形容词性物主代词：myour, youryour, his/her/itstheir名词性物主代词：mineours, yoursyours, his/her/itstheirs。第6、7小题即是如此。8. What are these in English?9. We are (some) drivers.在把单数句子变为复数句子时，连系动词be需要作相应的变化：(be)am/isare。第8、9小题即是如此。10. They have (some) pencil sharpeners.11. Are they (any) pears?a/an表示“一个”，只能用在单数可数名词之前，在把单数句子变为复数句子时，一定要把a/an去掉，或改为some/any。第10、11小题即是如此。12. These are my pens.13. They like their bikes.在把单数句子变为复数句子时，一般情况下，形容词性物主代词不需要改为复数形式。第12小题即是如此；但是当句中形容词性物主代词与句中的主语一致时，该物主代词应随主语人称的改变而变化，仍要保持一致。第13小题即是如此。14. Are those (any) apple trees.15. They are (some) men doctors.在把单数句子变为复数句子时，起修饰作用(作定语)的名词一般保持不变，只将其后的名词改为复数形式。第14小题(如apple)即是如此；但是，若man或 woman做定语修饰可数名词时，在整个句子变成复数的情况下也要变成 men 或women。第15小题即是如此。16. What are your telephone numbers？17. Where are your computers？18. Are you in Class One? 在把单数句子变为复数句子时，第二人称形容词性物主代词your与其人称代词you单复数同形，因此只需要改变其他部分的单复数形式即可。如第16、17、18小题即是。19. -Are those their brothers? -No, they arent.20. -Are they our teachers? -Yes, they are.在把单数句子变为复数句子时，句式不能改变，即单数句子是疑问句，变为复数句子时仍然是疑问句。第19、20小题即是。21. We are at home.22. They can have a look at these pictures.凡事都有特殊情况，在把单数句子变为复数句子时，一些固定短语(如at home，have a look等)中的单数可数名词是不可以改变的，仍然保留原先的单数形式。如第21小题中的home，第22小题中的look即是如此。【解题口诀】当同学们掌握了名词变复数的基本方法之后，再记住下面的口诀。相信单数句变复数句这一语法难点便会迎刃而解。单数句子变复数，变化规则要记住。名词代词要变化，am, is要变are。this, that变成啥，these, those来替它。he, she, it要变啥，全部变they不用怕。I变we莫落下，名词后面把-s/-es加。名前冠词去掉它，其余成分原样加。名词定语别管它，man与woman是例外。一般规则照着用，固定短语分清楚。初一英语名词单数变复数测试题一: 名词单数变复数填空1：:orange text bed computer .apple house plane tree lesson apple shirt month 2：piano photo radio zoo tomato .potato :3：class fox watch glass dress class .brush box bus :4：shelf knife wife life .leaf thief :5：family country army .city story baby butterfly country :6：m toy .play day key boy 二：代词/ be动词单数变复数 this _ that _ I _ you _ she _he _ it _ am _ is _三：把下列的单词变为复数形式key boy family case backpack dictionary watch computer game notebook bag math alarm video tape hat pear egg apple carrot vegetable star sock shirt shoe skirt sweater clerk store shop_四：句子单数变复数1：This is a book. . _2: That is an eraser. _3: It is a red apple. _4: I am a boy. _5: He / She is a teacher. _6: Whats this? _五：名词复数变单数练习1：Those are my friends._2: They are English boys. _3: They are some erasers. _4: These are dictionaries. _5: we are students. _6: what color are your books ? _六：根据句意及所给单词填空。1：_(this) are my English books.2: The two boys are my _(cousin)3: - _those your parents? -Yes, they _.4: -Who are the man and the woman in the picture? -They are my _.5: My aunt Jane and my mother are _.6: They are my _(姨)。7: I have two _(watch).
