老于帶你一字不背理解所有語法知識!

五種句型
1.sv,主語獨立完成動作,不及物動詞,帶賓語需要介詞
2.svo,主語需要賓語才可以完成動作,及物動詞
3.svoo,雙賓結(jié)構(gòu),具備傳遞性,沒有兩。個賓語就不完全
4.svoc,帶上了補語,讓語義完整
5.svc,主系表,表語就是補語,系動詞都表示是

1.名詞是名詞詞組,限定詞,形容詞,名詞復(fù)數(shù)
2.因為名詞有單復(fù)數(shù)形式,所以需要a,an,形容詞來判斷名詞的復(fù)數(shù)形式
3.不可數(shù)名詞,抽象名詞,復(fù)數(shù)形式都不需要限定詞
4.聯(lián)系上下文可以用限定詞代替
5. 形容詞永遠可以省略
例子
如a new book【形容詞可以省略】
the best answers【省略需要上下文】
i wate those【語意完整,限定詞替換名詞】
如 of these answers,this one is the best
those sweet rose
i want rose
定冠詞 the,【that,these,those】【清楚和簡潔】
1,特指加the
2,專有名詞,不需要特指限定詞
3,名詞做形容詞需要限定詞
4,the加形容詞表示一類人
補充,名詞的格
加‘s
the b of a
以及雙重,兩個都有
五,不定式,不定式是助動詞的簡化形式,同樣具有推測性和不確定性,
用法是從現(xiàn)在推未來從現(xiàn)在推過去。
2,to+v
3,從現(xiàn)在到對過去的推測,需要to,have
4,非謂語動詞包含
不定試,動名詞
5. s v o to do? do doing?
1.把不定式當初助動詞簡化,助動詞
They plan to marry next month.
They plan that they will marry next month.
2.+to do 表示推測,將來
所以這種情況就是不定式。
+ing是持續(xù),非不定式
感官動詞用原型是一瞬間,+ing是持續(xù),
6.使役動詞,裸不定式。
助動詞是輔助動詞,
語法助動詞;be do,have、to
語氣助動詞,
can,could,shoud。may,
must might
i do it,
i can do it
i may do it
i,maghtt it
不定式為了精簡和準確
i am glad to see you
i am glad because i am able to see you
i am glad to see you
不定式,助動詞的簡化
i will go
i want to go
都需要動詞原型,以及都有不確定性,推測性
He is right,
he may be right.
He seems to be right.
it is rain now
it must be raining now
it might even snow
it rained last night
it muat have rained last nihght

表示現(xiàn)在對過去的推測
非謂語動詞包含
不定式動名詞,
動名詞
現(xiàn)在分詞
p6動名詞

i try doing 盡力去
1,公式,v加ing做 有持續(xù)意義的名詞
2,v+ing=n 例,let me buy you a drink
drinking is hobby
3,形容詞不可以有復(fù)數(shù)
4,省略that和第n個主語加上動名詞
p7
過去分詞 ing 正在
現(xiàn)在分詞 ed 已經(jīng),被
