【grammar】
1.一般现在时一般疑问句和否定句的变法
一、先将句子分成三类:
1)含有am, is, are 的句子。
2)含有行为动词的句子,(如like,have,play,eat,
run,need)
3)含有情态动词的句子,如can。
(1)如果是第一类,即含有am, is, are 的句子。
只将
把am, is, are 调到句首。
I am 和We are 要变成are you,some变成any,my变成your,句末用问号。
否定句只在be后加not。
如am---am not; is ---isn’t; are----aren’t。
如:① I am a boy. (否定句)----- I am not a boy. (变成一般疑问句) -----Are you a boy? Yes,
I am. No, I’m not.
② She is my mother.( 变成一般疑问句) -----Is she your mother? Yes, she is. No, she isn’t. ③This is a book.( 变成一般疑问句) ------Is this
a book? Yes, it is. No, it isn’t.
④These are strawberries.( 变成一般疑问句) ----Are these strawberries? Yes, they are. No, they aren’t.
⑤ There is some chicken on the table.( 变成一
般疑问句) -----Is there any chicken on the table? Yes, there is. No, there isn’t.
(2)如果是第二类,即含有行为动词的句子(如like,have,play,eat,run,need等)时,要分两步看主
语。
①I / We / You / They 时,要借助于助动词do的帮
助来变成一般疑问句。
即句型为: Do + 主语 + 动
词原形 + 其他?否定句只在动词原形前加don’t。
例如:I have some tomatoes in my backpack.
(否定句)I don’t have any tomatoes in my backpack. ( 变成一般疑问句)-----Do you have any tomatoes
in your backpack? Yes, I do. No, I don’t. We play sports every day.
(否定句)---We don’t play sports every day. ( 变成一般疑问句)----Do you play sports every day? Yes, we do. No, we don’t.
②He / She / It 时,要借助于助动词does的帮助
来变成一般疑问句。
即句型为: Does + 主语 + 动词原形 + 其他?否
定句只在动词前加doesn’t,然后将单三还原成原形。
She watches TV every evening. (否定句)---She doesn’t watch TV every evening.
( 变成一般疑问句)----Does she watch TV every evening? Yes, she does. No, she doesn’t. 注意:如果是其他名词的话,在简略回答中要用人称代
词来替代,但替代都在第三人称中,即 he, she, it,
they四个中。
如: my mother ---she your brother ---- he a book ----it five photos-----they this/that-------it these/those------they my family name-----it Tom----he Mary--------she Amy’s sister -----she some friends------they
(3) 如果是第三类情态动词,如can 时,一般疑问句
只将can提到句首,否定句将can 变成can’t。
同时
注意一变二,二变一,三不变,some变any。
(情态动
词不受人称的限制)
I can play basketball. ( 变成一般疑问句)---- Can you play basketball? Yes, I can. No, I can’t. I can play basketball.(否定句)-----I can’
t play basketball.
2.名词变复数的规则
一般规则:+s 如:apple→apples,town→towns
以s, x, ch, sh结尾的名词: +es,如:bus→buses, box→boxes, bush→bushes, watch→watches
以o结尾的名词,有生命的加es,如:potato→potatoes, tomato→tomatoes, hero→heroes;无生
命的加s,如:radio→radios, photo→photos
以y结尾的名词,元音加y结尾直接加s,如boy→boys,
key→keys;以辅音加y结尾的名词,去y改i加es,如country→countries, library→libraries
以f, fe结尾的名词,去f变v加es,如:wolf→wolves, wife→wives(特例:roof→roofs)
【常用句型】
1.They can stand on their hands.他们可以倒立。
