【专家解析】单数句变复数句涉及名词和动词的人称和数，人称代词、物主代词、指示代词的人称和数的问题。单数句变为复数句时，上述各类词都要做相应变化，其它词类不变。当然，也有一些特殊的情况。
　 1. These are (some) chairs.
2. 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：
this→these, that→these。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：I→we, you→you, he/she/it→they
　　宾格：me→us, you→you, him/her/it→them。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：my→our, your→your, his/her/its→their
　　名词性物主代词：mine→ours, yours→yours, his/her/its→theirs。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/is→are。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 aren’t.
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。
