this,these, that, those 这四个词的用法

上节课我们学习了11-12的数字,以下请特别注意:
1 .11 eleven / 12 twelve 要特殊记忆
2 .13-19 后面要加teen['ti:n],单词的重音在teen上。特殊记忆13/15/18这三个数字。
13 thirteen/ 15 fifteen/ 18 eighteen
3 .‘几十'后面加‘ty’,特殊记忆20/30/40/50/80这几个数字
今天我们讲了特殊疑问词whose (谁的)的用法,因为whose与who's(谁是)的读音一样, 所以小朋友在做听力的时候一定要知道如何区分这两个单词。
whose(谁的):它是问这个物品/东西是属于谁的?是问跟东西有关系的。 who's (谁是): 它是问跟人有关系的。
1 one (代替单数)和 ones(代替复数)
我们用one 或ones 来代替上文提及过的名词
例如: Whose T-shirt is that? 那是谁的T恤?
Which T-shirt? 哪件?
The yellow one. 黄色的那件。
2 今天我们讲了物主代词
物主代词是表示所有关系的代词。它可分为形容词性物主代词和名词性物主代词。
形容词性物主代词: my your his her its our your their
名词性物主代词: mine yours his hers its ours yours theirs
轻松记忆:除了mine外,名词性物主代词都是在形容词性物主代词后面加‘s’构成。如果本身
就是以s结尾,就不用变了。
用法:
形容词性物主代词只能作定语,后面一定要跟一个名词,不能单独使用 my book/your pencil
名词性物主代词可以单独成立,但是必须有上文提及过的名词。
名词性物主代词=形容词性物主代词+名词
This book is mine.= This is my book.
二十 twenty/ 三十 thirty/四十 forty/五十 fifty/八十 eighty/

1 Whose are these shoes? (注意当鞋,袜子,裤子,眼镜等这些名词出现时,BE动词要用are, 代词必须用these/those.不能用this/that.)
2 They aren't mine!(they 代替的是鞋,袜子,裤子,眼镜等这些名词) 3 Let's play hide and seek.(let's +V原型,后面一定要跟动词的原型,用法要区别like.) 4 I like playing hide and seek. 5 I am coming.( 我要来了,表示即将要做的动作) 6 Well done! 做得好! 7 I win.我赢了。 8 I am from China.(be from„来自于。。。) 9 This is a picture/photo of me.(注意of的用法,。。。的) 10 There are two beds and a small chair.(注意there be 句型的就近原则)
今天我们学习了正在进行时的这种句子时态 其构成为 主语+BE动词+Ving(动词的ing形式)
1.单数第三人称作主语的时候,我们要把后面的动词/助动词变成(加“s/es”) She wants to be a doctor.
She enjoys reading about science.
2.like/enjoy/love +ving (要加动词的Ing形式) Because he loves riding his bike. She enjoys reading about science.
3.正在进行时的构成是 “主语+BE动词+Ving”
This person is reading a book to her daughter
1.单数第三人陈做主语的时候,后面的实义动词要变成三单形式。例如: He likes swimming. He does his homework at nine o'clock.
2.频率副词的用法。
频率副词在句子中的位置:主语+频率副词+动词。 I always swim on Mondays.
She sometimes plays the piano in the evening.
He never plays the computer games.
就频率副词提问,我们要用how often 这个特殊疑问词。 How often do you play in the park ? How often does he go swimming?
频率副词的频繁程度有强到弱为always(总是)——sometimes(有时候)——never(从不)
