解析与学生常见错误提醒
1. 参考答案:It is not sunny today. / It isn't sunny today.
解析:含有be动词(is)的句子,变否定句直接在be动词后加not。
学生常见错误提醒:错误地写成“It not is sunny today.”或“It doesn't sunny today.”。
2. 参考答案:Emma does not like snowy winter. / Emma doesn't like snowy winter.
解析:主语是第三人称单数(Emma),谓语是实义动词(likes),变否定句需借助助动词does,后加not,并将likes还原为like。
学生常见错误提醒:忘记将动词还原(如:Emma doesn't likes...),或错误地只加not。
3. 参考答案:Lucas can not swim in the lake. / Lucas can't swim in the lake.
解析:含有情态动词(can)的句子,变否定句直接在can后加not,可缩写为can't。
学生常见错误提醒:错误地写成“Lucas doesn't can swim...”,或在can后面加don't。
4. 参考答案:问句:Is the Spring Festival in January?
肯定答:Yes, it is.
解析:含有be动词(is)的陈述句变一般疑问句,将be动词(is)提前至句首。主语the Spring Festival用it指代。
学生常见错误提醒:忘记将be动词提前,或答语中主谓不一致。
5. 参考答案:问句:Is there a big park near the school?
肯定答:Yes, there is.
解析:There be句型的陈述句变一般疑问句,将be动词(is)提前至句首。
学生常见错误提醒:忘记将be动词提前(如:There is a big park near the school?),或答语不简练。
6. 参考答案:问句:Is it Children’s Day tomorrow?
肯定答:Yes, it is.
解析:含有be动词(is)的陈述句变一般疑问句,将be动词(is)提前至句首。
学生常见错误提醒:忘记将be动词提前,或答语中主谓不一致。
7. 参考答案:问句:Does Noah walk to the zoo on Sunday?
肯定答:Yes, he does.
解析:主语是第三人称单数(Noah),谓语是实义动词(walks),变一般疑问句在句首加助动词Does,并将walks还原为walk。
学生常见错误提醒:忘记将动词还原(如:Does Noah walks...),或答语中动词未还原(如:Yes, he walks.)。
8. 参考答案:What is your favourite season?
解析:对季节(spring)提问,用疑问词What。句子是be动词is,疑问句中is提前。物主代词my变为your。
学生常见错误提醒:用Which提问(也可以,但What更常用),或忘记将my变为your。
9. 参考答案:How is the weather in spring in Chengdu? 或 What's the weather like in spring in Chengdu?
解析:对天气状况(warm and rainy)提问,用固定句型How is the weather? 或 What's the weather like? 主语it变为the weather。
学生常见错误提醒:错误地用What提问天气(如:What is the weather? 不地道),或忘记将it变为the weather。
10. 参考答案:Where is the hospital?
解析:对地点(next to the bank)提问,用疑问词Where。句子是be动词is,疑问句中is提前。
学生常见错误提醒:用What提问,或将be动词遗漏(如:Where the hospital is?)。
11. 参考答案:Where do you fly kites?
解析:对地点(in the park)提问,用疑问词Where。主语是we,疑问句中变为you,时态是一般现在时,用助动词do。
学生常见错误提醒:用What提问,或忘记使用助动词do。
12. 参考答案:How many red lights are there on the street?
解析:对可数名词的数量(five)提问,用疑问词组How many。There be句型疑问句中be动词(are)提前。
学生常见错误提醒:用What提问,或语序错误(如:How many red lights there are...?)。
13. 参考答案:Who can go to the supermarket by bus?
解析:对人物(Wang Jun)提问,用疑问词Who。句子有情态动词can,疑问句中can提前。
学生常见错误提醒:用What提问,或错误改变情态动词位置(如:Who Wang Jun can go...?)。
14. 参考答案:These are green traffic lights.
解析:单数变复数,this → these,is → are,a green traffic light → green traffic lights。traffic light是可数名词短语,变复数在最后一个单词后加s。
学生常见错误提醒:忘记改变指示代词和be动词,或名词短语复数形式错误(如:traffics lights)。
15. 参考答案:Those children watch TV at home in winter.
解析:that → those,child → children(不规则),watches → watch(主语复数),TV → TV(不变)。
学生常见错误提醒:child的复数形式写错(childs),或忘记将动词改为watch。
16. 参考答案:Here come the winds.
解析:Here comes + 单数名词,变成Here come + 复数名词。主语由the wind(单数)变为the winds(复数),谓语动词也相应由comes变为come。
学生常见错误提醒:忘记改变谓语动词(如:Here comes the winds. ❌),或wind的复数形式不常用,但此规则适用于此类倒装句。
17. 参考答案:问句:Do you like windy weather?
否定答:No, I don't.
解析:主语是第一人称(I),谓语是实义动词(like),变一般疑问句在句首加助动词Do,并将主语变为you。
学生常见错误提醒:忘记将I变为you,或答语中人称错误。
18. 参考答案:问句:Are they in Shenyang now?
否定答:No, they aren't.
解析:含有be动词(are)的陈述句变一般疑问句,将be动词(are)提前至句首。
学生常见错误提醒:忘记将be动词提前,或答语中主谓不一致。
19. 参考答案:问句:Can you see snow in January?
否定答:No, we can't.
解析:含有情态动词(can)的陈述句变一般疑问句,将can提前至句首。主语we在问句中变为you。
学生常见错误提醒:未进行人称转换(如:Can we see snow...?),或答语中人称错误。
20. 参考答案:问句:Is the library behind the restaurant?
否定答:No, it isn't.
解析:含有be动词(is)的陈述句变一般疑问句,将be动词(is)提前至句首。主语the library用it指代。
学生常见错误提醒:忘记将be动词提前,或答语中主谓不一致。
21. 参考答案:问句:Does Liu Yi put on his coat in winter?
否定答:No, he doesn't.
解析:主语是第三人称单数(Liu Yi),谓语是实义动词(puts),变一般疑问句在句首加助动词Does,并将puts还原为put。注意短语put on中on是副词,动词put要还原。
学生常见错误提醒:忘记将动词还原(如:Does Liu Yi puts on...),或答语中动词未还原。
