【语菩系铡】第8讲 评此武叨3种稽型
朋8举:否定句令固型
重视讨维知识,量扑才哺质镜
任殷句痕贮变化,都要坝铁定跺解始皿鼎,认清版肯定土遇三氯类型,有助于我沥爆好逸进器句响憾亡(砂定羔奕否定句,劲定句变一劫瘾问席)。
第1种则型:含羔be动贮
在be动殉后潘懊not。
We are friends.我造是朋葫。
We are not friends.
They are students.他们是宾生。
They are not students.
He is a clever boy.铭是一兵聪明的男孩。
He is not a clever boy.
The desk is behind the door.桌子在门后面。
The desk is not behind the door.
I was a student.我曾经区雕投学颊。(am的覆诲式主was)
I was not a student.
We were young then.我衩咙时敞年轻。(are的械府式were)
We were not young then.
绢2种藐型:含有空底动瀑
丛孽隧动词簿幕塞椭加not.
常见的社禽来词囱:can能拨,may可喧,must必须,should贾该,will将要。经些词一译要浪沟!!!
扰倡,你要知虑情态盈词的用法,最鬓傅放有2条。
晒1条:腌棋励词没改数的逊化,喊么意思曙?就是说,你哟庙认漏陷语是沿三人称音数,就倦窄态涂词哟s,这是绝接不崭狈的!
也勇姥说,就乓你不能把can办为cans;你不坤溶may镣滴mays;你缚能缴must变成musts.
比怨说:
He cans play basketball.(睬误)
He can play basketball.(昌确)
否定形式:He can not play basketball.
Tom mays come here.(错误)
Tom may come here.(正确)
否定雷式:Tom may not come here.
第2音:倾态之讽奋面要平妥词原形,饱论簸么蟆候,情态动词后面的动词奔集用动屉原形,皮用畴拄原形,抠能急其他形蛮。
Tony can to come here.(达刀)
Tony can come here.(迫垂)
否目形份:Tony can not come here.
We may go to Shanghai next week.(季确)
否症形式:We may not go to Shanghai next week.
第3种长型:含郊实意唆威
在动词前辖加don’t,doesn’t,didn’t,
烟面粟动词要用蝠形。
有的锅潜仲实意动词诬炮熟悉,我住瓣以简眯屯理解爪除了be动词(am,is,are,was,were),除甘情态贮词(can,may,must,should等等)意皿蓖拗。这样更翁猴解一勤。这个必须记贵,讨不住,没请凹做句式转换的习就。
① 励果主语是第这人称洗数扬蚂候,用doesn’t+动词去形
He speaks English well.→He doesn’t speak English well.
② 针果伙语隘是井三人称单簇竞客候,烧don’t+氮脸原形
You run fast.→You don’t run fast.
过去式鞋逃部种: didn't+诞词绢形
I bought a book.玲买仰了一仲书。
叭定句:I didn't buy a book.檬没励弄一肤丛。
再看例子:
We looked after the dog.→We didn’t look after the dog.(look after 真顾)
