原始起源
英語(yǔ)是一門(mén)逐漸發(fā)展演變的語(yǔ)言,早在遠(yuǎn)古時(shí)期,英語(yǔ)的結(jié)構(gòu)其實(shí)只有以下這兩種,即簡(jiǎn)單句的原始結(jié)構(gòu)。
主+謂+賓 主+系+表
主語(yǔ):主語(yǔ)是一個(gè)句子所敘述的主體,一般位于句首。在原始的簡(jiǎn)單句中,主語(yǔ)可由名詞、代詞、數(shù)詞、名詞化的形容詞表示。例如:
During the 1990s, Americancountry musichas become more and more popular.(名詞)
Weoften speak English in class.(代詞)
One-thirdof the students in this class are girls.(數(shù)詞)
The richshould help the poor.(名詞化的形容詞)
謂語(yǔ)(動(dòng)詞):謂語(yǔ)說(shuō)明主語(yǔ)所做的動(dòng)作或具有的特征和狀態(tài)。動(dòng)詞在句中作謂語(yǔ),一般放在主語(yǔ)之后。謂語(yǔ)的構(gòu)成如下:
1.簡(jiǎn)單謂語(yǔ):由一個(gè)動(dòng)詞或動(dòng)詞短語(yǔ)構(gòu)成。如:He practicesrunning every morning.
2.復(fù)合謂語(yǔ):(1)由情態(tài)動(dòng)詞或其他助動(dòng)詞加動(dòng)詞原形構(gòu)成。如:You may keepthe book for two weeks. He has caughta bad cold. (2)由系動(dòng)詞加表語(yǔ)構(gòu)成。如:We are students.
在英語(yǔ)中一個(gè)簡(jiǎn)單句只能有一個(gè)謂語(yǔ)動(dòng)詞(知道為什么嗎),而且,我們平時(shí)學(xué)習(xí)的時(shí)態(tài)是針對(duì)謂語(yǔ)動(dòng)詞來(lái)說(shuō)。如果以do為例,do, did ,have done, will do, had done, is/am/are doing, was/were doing, would do。在簡(jiǎn)單句中,謂語(yǔ)動(dòng)詞和主語(yǔ)是句子的核心,是不可以隨意刪掉的。
賓語(yǔ):賓語(yǔ)表示動(dòng)作的對(duì)象或承受者,一般位于及物動(dòng)詞和介詞后面。例如:
They went to see an exhibition(展覽)yesterday.(名詞)
The heavy rain prevented mefrom coming to school on time.(代詞)
How many dictionaries do you have? I have five.(數(shù)詞)
They helped the oldwith their housework yesterday.(名詞化形容詞)
表語(yǔ):表語(yǔ)用以說(shuō)明主語(yǔ)的身份、特征和狀態(tài),它一般位于系動(dòng)詞(如be, become, get, look, grow, turn, seem等)之后。表語(yǔ)一般由名詞、代詞、形容詞、分詞、數(shù)詞。
Our teacher of English is anAmerican.(名詞)
Is it yours?(代詞)
The weather has turned cold.(形容詞)
The speech is exciting.(分詞)
Three times seven is twenty one?(數(shù)詞)
