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在can,should,will等后加not。如:can not,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 a girl.→ 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 not Tom’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(am,is,are)放在句首,第一个字母大写,剩下的照抄,句末用问号。(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,第一个字母大写,剩下的照抄,句末用问号。(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:I am 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 an English 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 a book.---What is this?I often play football 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 my brother.---Who is he?3、划线部分是“地点”,特殊疑问词用where如:The box is on 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 seven twenty.---What time is it?I usually get up at six.---When do you usually get up?5、划线部分是“年龄”,特殊疑问词用how old如:I am twelve.---How old are you?Myfatheristhirty-three.---Howoldisyourfather?6、划线部分是“职业”,特殊疑问词用what如:Mike is a worker.---What is Mike?7、划线部分是“颜色”,特殊疑问词用what colour如:My hat is blue.---What colour is your hat?8.划线部分是“数量”,特殊疑问词用how many或how much如:I can see five kites.---How many kites can you see?There is some milk in the glass.--- How much milk is there in the glass?9.划线部分是“多少钱”,特殊疑问词用how much如:This pen is nine yuan.---How much is this pen?10.划线部分是“形容词性物主代词或名词性物主代词”,特殊疑问词用whose如:That is my book.---Whose book is that?The bag is yours.---Whose is the bag?以下口诀要牢记:1.问“谁”用who;2.问“谁的”,用whose;3.问“地点哪里”,用where;4.问“原因”,用why;5.问“身体状况”,用how;6.问“方式”,用how;7.问“年龄”,用how old;8.问“多少”,用how many;9.问"价钱”用how much;10.问“哪一个”,用which;11.问“什么”,用what;12.问“职业”,用what;13.问“颜色”,用what colour;14.问“星期”,用what day;15.问什么学科,用what subject;16.问“什么时候”,用when;17.问几点用What’s the time?或What time is it?
