任何一個英文句子都離不開主語+動詞的結構,如果主語省略形成祈使句,其實就是省略了主語,另語氣更重
主語+動詞: i am a student(i為主,am為動詞);he left.he laughed.ect.(這是完全不及物的句子,後面不加其他句子也能形成)
祈使句:Be quite,這就是省略了(you should )be quite,語氣重,可以說don&39;t就成了否定句
既然我們得知英文句子中,主語和動詞都不可或缺,那我們首先是以主語為先,來闡述有哪些可以做主語的
●1. 代詞:i you he she they it that ,人物:如小明,小紅等第三人稱,
●2. 名詞:如desk :desk is mine
●3. 不定式做主語:to + 動詞 to study (表示目的、有意向的,或者是沒有完成的)
To go to shopping is my hobby 愛好是已知的,所以這句話存在漏洞的,但不能時說錯誤,愛好是有意向的,但具有模糊性
To go to shopping is my plan in this afternoon 意向有目的
●4. 動名詞做主語:V+ing ,sleeping :sleeping is my hobby
知識梗:
如果不定式或動名詞做主語過長時,整體句子容易造成頭重腳輕,我們可以用It作為形式主語,放在前,而真正的主語則放在後面,當動名詞放後面時則需改成不定式短語(不定式不變)
E. G:動名詞designing door handle is one of my profession = it is one of my profession to design door handle
不定式to travel make me happy=it make me happy to travel(動詞還是不熟悉,感覺句型有小許問題,下兩篇認證)
使用教材例子to study abroad is my greatest desire=it is my greatest desire to study aboard
●5. 名詞性從句做主語
可概括三大類that \疑問句\ weather(一般疑問句,即回答yes \no)
That
疑問句:6W1H(6w:what\who\when\where\why\which 1H:how)
A. that:he is my friend Ted 變從句--->that he is my friend Ted
B. weather :be 動詞----> is he happy?變從句---->weather he is happy
一般助動詞(can, will, may ,should, ought to,must ,have)have i a tool for car repairing? 變從句---->weather i have a toll for car repairing
助動詞(do,does ,did)does he go to shopping? 變從句---->weather he does go to shopping--->weather he goes to shopping
C. 疑問句(6w:what\who\when\where\why\which 1H:how)也跟weather相類似的句型變化,但weather是在一般疑問句不出現,轉為名詞性從句才出現,但疑問句(6W1H)則開始時出現,只是由大寫改為小寫,另外動詞和代詞或名詞之間調換位置
Be動詞What is he doing?變從句----> what he is doing
一般助動詞(can,will,may,should,must,need,ought to ,have)what can i do for you變從句----> what i can do for you
助動詞do ,does, did what did he write變從句----> what he did write----> what he wrote
如果(6w1h,如果直接做主語的時候,不變)
同樣如果名詞性從句如果太長,可以形式主語it代替,而他則往後移,在下一篇幅細說,這裡不敘說
●6. 名詞性短語
疑問副詞
where to live
weather to try again
how to do it
疑問代詞
what to do
whom to see
●7. 表距離的from
From +名詞 to 名詞
from shanghai to beijing is about 1000 kilometers
以上7種均可以用作主語
