答题技巧
一、 第一步:辨类型,不跑偏
先看题目要求,分清是要变 否定句、一般疑问句,还是 对划线部分提问,别瞎忙活!
二、 第二步:找 “开关”,秒变身
句型转换的 “开关” 就是句子里的动词,盯紧它就对了!
①句子有 be 动词(am/is/are)或情态动词(can/may)
变否定句:直接在 be 动词 / 情态动词后面 加 not例:He is tall. → He is not tall.例:She can swim. → She can not swim.
变一般疑问句:直接把 be 动词 / 情态动词 提到句首,I 变 you,my 变 your例:I am a student. → Are you a student?例:We can fly kites. → Can you fly kites?
②句子只有实义动词(如 play/eat/like)
请出 助动词 do/does 来帮忙!
主语是三单(he/she/it/ 单数名词)→ 用 does;其他情况 → 用 do
变否定句:主语 + do/does + not + 动词原形例:She likes cats. → She doesn’t like cats.(does 一出,likes 变回原形)例:They play football. → They don’t play football.
变一般疑问句:Do/Does + 主语 + 动词原形例:He plays basketball. → Does he play basketball?例:I watch TV every day. → Do you watch TV every day?
③对划线部分提问(变特殊疑问句)
第一步:选 疑问词(看划线部分问啥)
第二步:把剩下的句子变成一般疑问句的形式例:She goes to school by bike. → How does she go to school?
三、 第三步:查细节,补满分
改完别直接交卷!做好这 3 件事:
人称要对应:I → you,my → your,we → you
格式要正确:句首单词首字母大写,句末标点变问号(疑问句)
通读要通顺:把改好的句子读一遍,别扭的地方赶紧改!
