解析与学生常见错误提醒
1. 参考答案:Lucas cannot play football. / Lucas can't play football.
解析:含有情态动词“can”的肯定句变否定句,直接在“can”后面加“not”,缩写为can’t。
学生常见错误提醒:写成“Lucas doesn’t can play...”(错误添加助动词)。
2. 参考答案:Emma would not like any milk. / Emma wouldn’t like any milk.
解析:含有“would like”的肯定句变否定句,在“would”后加“not”,缩写为wouldn’t。同时,肯定句中的some在否定句中通常要改为any。
学生常见错误提醒:忘记将some改为any,或写成“Emma not would like...”。
3. 参考答案:The book is not under the desk. / The book isn't under the desk.
解析:含有be动词“is”的肯定句变否定句,在is后面直接加“not”,缩写为isn’t。
学生常见错误提醒:写成“The book not is...”或“The book doesn’t under the desk.”。
4. 参考答案:问句:Is it time to get up?
肯定答:Yes, it is.
解析:含有be动词“is”的肯定句变一般疑问句,将“is”提到句首。主语It不变。
学生常见错误提醒:写成“Does it time to get up?” 或“Is it time for get up?”。
5. 参考答案:问句:Can Liu Yi swim in summer?
肯定答:Yes, he/she can.
解析:含有情态动词“can”的句子,变一般疑问句将“can”提到句首。Liu Yi可能是男性或女性,回答时用he或she皆可。
学生常见错误提醒:写成“Does Liu Yi can swim...?” 或“Can Liu Yi swims...?”。
6. 参考答案:问句:Does Wang Jun like playing basketball?
肯定答:Yes, he does.
解析:主语是第三人称单数“Wang Jun”,谓语动词是“likes”,变一般疑问句需在句首加“Does”,并将likes还原为动词原形“like”。Wang Jun是男性,回答时代词用he。
学生常见错误提醒:写成“Is Wang Jun like...?” 或“Does Wang Jun likes...?”。
7. 参考答案:问句:Does Noah wear a sweater in autumn?
肯定答:Yes, he does.
解析:主语是第三人称单数“Noah”,谓语动词是“wears”,变一般疑问句需在句首加“Does”,并将wears还原为动词原形“wear”。Noah是男性,回答时代词用he。
学生常见错误提醒:写成“Is Noah wear...?” 或“Does Noah wears...?”。
8. 参考答案:Where is your pen?
解析:对地点“on the chair”提问,用特殊疑问词“Where”。My变为your,is提到句首。
学生常见错误提醒:写成“Where your pen is?”(语序错误)或“What is your pen?”。
9. 参考答案:What would you like?
解析:对想要的事物“some eggs and bread”提问,用“What”。主语I变为you,would提到句首。
学生常见错误提醒:写成“What you would like?”(语序错误)或“What do you like?”(混淆“喜欢”和“想要”)。
10. 参考答案:When do you play ping-pong?
解析:对时间“on Wednesday”提问,用“When”。主语I变为you,谓语动词play是原形,变疑问句用“do”。
学生常见错误提醒:写成“What day you play ping-pong?” 或“When you play ping-pong?”(漏助动词do)。
11. 参考答案:What is your favourite season?
解析:对最喜爱的事物“summer”提问,用“What”。My变为your,is提到句首。
学生常见错误提醒:写成“What your favourite season?”(漏be动词)或“What season do you favourite?”。
12. 参考答案:What can you do in the park?
解析:对能做的活动“run and jump”提问,用“What...do?”。主语I变为you,can提到主语前。
学生常见错误提醒:写成“What you can do in the park?”(语序错误)或“What can you in the park?”(漏了助动词do)。
13. 参考答案:What is it time for?
解析:对“for”后面的名词“lunch”提问,用“What...for?” 或 “What time is it?”。但根据教材常用句型,此处用“What is it time for?” 更合适。Is提到主语it前。
学生常见错误提醒:写成“What time is it?”(答案不唯一,但更常见是问钟点)或“What is it time?”(漏介词for)。
14. 参考答案:We are students.
解析:单数变复数,I变为We,am变为are,a student变为students。
学生常见错误提醒:student的复数直接加s,注意拼写。忘记将a去掉。
15. 参考答案:These are our coats.
解析:单数变复数,This变为These,is变为are,my变为our,a coat变为coats。
学生常见错误提醒:coat的复数直接加s,注意拼写。my的复数形式是our。
16. 参考答案:They are good boys.
解析:单数变复数,He变为They,is变为are,a good boy变为good boys。
学生常见错误提醒:boy的复数直接加s。注意拼写。
17. 参考答案:问句:Is the bag on the desk?
否定答:No, it isn't.
解析:含有be动词“is”的肯定句变一般疑问句,将is提到句首。主语The bag用it指代回答。
学生常见错误提醒:写成“Does the bag on the desk?” 或答语“No, it doesn’t.”。
18. 参考答案:问句:Can I make a snowman in winter?
否定答:No, you can't.
解析:含有情态动词“can”的句子,变一般疑问句将“can”提到句首。主语You回答时用I。
学生常见错误提醒:写成“Do I can make...?” 或“Can you makes...?”。
19. 参考答案:问句:Does Emma like noodles?
否定答:No, she doesn't.
解析:主语是第三人称单数“Emma”,谓语动词是“likes”,变一般疑问句需在句首加“Does”,并将likes还原为动词原形“like”。Emma是女性,回答时代词用she。
学生常见错误提醒:写成“Is Emma like noodles?” 或“Does Emma likes noodles?”。
20. 参考答案:问句:Does Lucas wear shorts in summer?
否定答:No, he doesn't.
解析:主语是第三人称单数“Lucas”,谓语动词是“wears”,变一般疑问句需在句首加“Does”,并将wears还原为动词原形“wear”。Lucas是男性,回答时代词用he。
学生常见错误提醒:shorts是复数名词,前面没有a,但谓语动词wear仍用原形。易写成“Does Lucas wears...?”。
21. 参考答案:问句:Is it time to go to school?
否定答:No, it isn't.
解析:含有be动词“is”的肯定句变一般疑问句,将is提到句首。主语It不变。
