一、肯定句改否定句的方法: 1、 在be动词后加not。如:is not , are not , am not 2、 在can,should, will等后加not。如:cannot, should not, will not; 3、 上述都没有的,在动词前加助动词否定形式don’t/doesn’t/didn’t。 4、 some 改成any。 如: I am agirl. → I am not a girl. You are a student. →You are not a student. →You aren’t a student. This is Tom’s bag, → This is notTom’s bag.→ This isn’t Tom’s bag.
二、肯定句改一般疑问句的方法 1、 把be动词放在句首,剩下的照抄,(some 改成any,I改成you,my改成your,)句点改成问号。 2、 把can,shall, will等放到句首,剩下的照抄,(some改成any,I改成you,my改成your,)句点改成问号。 3、 上述都没有的,在句首请助动词Do/Does/Did帮忙,剩下的照抄,(some改成any,I改成you,my改成your,)句点改成问号。 注意:句首的第一个字母要大写,句尾标点应为“?”。 如: Iam in Class 6. →Are you in Class 6? You are from America. →Are you from America? It is an orange. →Is it an orange? 4、 就一般疑问句回答 一般疑问句有两种回答,即:肯定回答和否定回答。其中,肯定回答用yes,否定回答用no。语句顺序为:Yes + 主语 + am /is/ are/was/were.|can.|do/does/did|; No + 主语+ am not/isn’t/ aren’t 如: —Are you anEnglish teacher?→Yes, I am. /No, I am not. —Is that a bird? →Yes, it is./No, it isn’t.
三、对划线部分提问 “就划线部分提问”是小学阶段英语学习的难点,但是一旦掌握了规律,就变得容易多了。 小学英语对划线部分提问之答题口诀: 一代:用正确的疑问词代替划线部分。 二移:把疑问词移至句首 三倒:颠倒主谓语,但对主语或其定语提问时除外(some 改成any,I改成you,my改成your), 四抄:照抄句子剩余部分。
★特殊疑问词的确定要根据划线内容而定,在小学阶段常出现的有以下几种: 1划线部分是“事或物”,特殊疑问词用what 如: This is abook.---What is this? I often playfootball on Saturdays .---What do you often do on Saturdays ? 2划线部分是“人”,特殊疑问词用who 如:He is mybrother. ---Who is he ? 3划线部分是“地点”,特殊疑问词用where 如:The box ison the desk.---Where is the box ? 4划线部分是“时间”,特殊疑问词用what time或when 如:It's seventwenty . ---What time is it ?
