把以下两个句子变成现在完成时:
1.He got a new television last weet.
2.We heard the news one the radio.

1. Did he get a new television last week?
He didn't get a new television last week.

2. Did you hear the news on the radio?
We didn't hear the news on the radio

1.He has got a new television since last week.
2.We have heard the news one the radio yet.

He has got a new television a week ago.
We have heard the news on the radio .

He has got a new television last week.
We have heard the news one the radio.
现在完成时的结构:have/has+pp(pp就是过去分词。)

.He has got a new television last weet.
We have heard the news one the radio.

名词的复数形式一般在单数后面加-S或-es (构成方法和发音规则)

s在清辅音后发/s/ 如.desks maps;
在浊辅音、元音后发/z/ 如.jobs workers;

es有两种情况:一般情况下同s,发音是/s , z/

感叹句是用来表达说话者说话时的惊异、喜悦、愤怒、气愤等思想感情的句子。其结构常由感叹词“What(How) 感叹的部分 主语 谓语!”构成。读时一般用降调。主要有以下两大句型:
一、由感叹词what引导的感叹句。
what修饰名词或名词短语,有以下两种形式:
1. What a(an) (形容词) 单数可数名词 主语 谓语!如:
What an apple this is!
What a fine day it is!

2. What (形容词) 可数名词复数或不可数名词 主语 谓语!
What kind women they are!
What nice music it is!

二、由How引导的感叹句。
how用来修饰形容词、副词或动词。其结构是:How 形容词(副词) 主语 谓语!
How hard the worker are working!
How clever the girl is!
How quickly the boy is writing!
注意:当how修饰动词时,动词不跟着感叹词提到主语之前。
How the runner runs!

三、what与how引导的感叹句,一般情况下可以相互转换,转换后意义不变。如:
What an interesting story it is!==How interesting the story is!
what a beautiful bulding it is!==How beautiful the building is!

四、在口语中,感叹句的主语和谓语常常省略。如:
What a nice present!(省略it is)
How disappointed!(省略she is或其它可作本句主、谓的词语)

感叹句的句型特点及做法:

一、如何快速掌握感叹句?
学会分析五种基本句型的句子成分是快速掌握感叹句的关键,陈述句变感叹句实际上就是句子成分位置的移动。
例1 She is smiling sweetly.
→How sweetly she is smiling!(移动状语)

二、哪些句子成分可能会移动位置?
通过对句子成分的分析我们就可以确定哪个句子成分需要挪动位置,一般说来含有形容词的名词短语、形容词短语和副词短语需要变动位置。位置可能会变动的句子成分:宾语、表语和状语。
例2 Mr Turner told us a funny story.
→What a funny story Mr Turner told us!(移动宾语含有形容词的名词短语)

三、如何确定使用what还是使用how?
当我们做句型变换或选择题时需要自己确定到底是用what还是用how,一般可以这样来确定:位于主语之前的是名词短语时用what,是形容词或副词短语时用how。但这种格式例外: how adj. a/ an N
例3 What a cool bike you are riding!(a cool bike 名词短语)
例 4 How fast he is riding!(fast 副词)
例 5 How cool a bike you are riding!(how adj. a/ an N)

四、如何判断是否使用冠词、使用什么样的冠词?
名词的复数形式和不可数名词之前不使用冠词,以元音音素开头的词语之前用an,以辅音音素开头的词语之前用a。
例6 What beautiful sunshine it is today!(sunshine 不可数名词)
例7 What a useful book this is!(useful 以辅音音素开头)
例8 What an old house that is!(old 以元音音素开头)

五、感叹句有哪几种格式?
简单地说是"两型七式":两种句型是以what开头的句型和以how开头的句型,七种格式是
① what a adj. N S V
② what an adj. N S V
③ what adj. N(不可数) S V
④ what adj. N(可数名词复数形式) S V
⑤ how adj. S V
⑥ how adv. S V
⑦ how adj. a/ an N S V
例 What exciting news it is!(what adj. N(可数名词复数形式) S V结构)
例9 What good teachers they are!(what adj. N(可数名词复数形式) S V结构)
例10 How warmly they are discussing!(how adv. S V结构)
例11 How beautiful a picture it is!(how adj. a/ an N S V 结构)

六、以what开头的句型和以how开头的句型怎样进行转换?
这两种句型之间的转换主要是指以下两种情况而言的:
⒈含有"a/ an adj. N "结构的句子方法是把形容词单独抽出来放在名词短语的前面和how搭配使用。
⒉名词短语作主语而表语是形容词的句子方法是把主语当作"a/ an adj. N"结构的中心名词而用人称代词充当主语。
例12 What an expensive glass he broke! →How expensive a glass he broke!
例13 How beautiful the birds are! →what beautiful birds they are!
(说明:N代表名词,未特别说明者代表可数名词的单数形式,S代表主语,V代表动词)

七、在感叹句中哪些词语常常省略?
常常省略的是充当主语的人称代词和动词be。
例14 What a naughty boy!(省略了he is
