52 基本規(guī)則 Track44
主謂一致:即指謂語(yǔ)動(dòng)詞人稱和數(shù)上要和主語(yǔ)一致。具體規(guī)則
如下:
(1)在一般現(xiàn)在時(shí)中,若主語(yǔ)是單數(shù)第三人稱,謂語(yǔ)動(dòng)詞要加-s或-es,具體變化同名詞的單數(shù)變復(fù)數(shù)。
He goes to school at 8:00 every morning.
不說(shuō):He go... 因?yàn)檫@里的主語(yǔ)he就是單數(shù)第三人稱。
1)單數(shù)第三人稱作主語(yǔ)的詞如:
單數(shù)人稱代詞:he,she,it
不定代詞:each,everyone
人名:John, Bill Gates
普通單數(shù)名詞:my brother,English
2)單數(shù)動(dòng)詞的變化有:
若主語(yǔ)是單數(shù)第一、第二人稱或復(fù)數(shù),則謂語(yǔ)動(dòng)詞用原形,不需要加-s或-es。這樣的主語(yǔ)有:
單數(shù)人稱代詞:I,you(你)
復(fù)數(shù)人稱代詞:we,you(你們),they
復(fù)數(shù)名詞:students,books……
(2)在助動(dòng)詞或情態(tài)動(dòng)詞后面,直接接動(dòng)詞原形。
a. She can sing in English. 不說(shuō):She can sings in English.*
b. He doesn't go to school early. 不說(shuō):He doesn't goes to school early.*
(3)There be句型須主謂一致。
a. There is a book on the desk.
b. There are two books on the desk.
There be句型是倒裝結(jié)構(gòu),因此謂語(yǔ)動(dòng)詞的單復(fù)數(shù)要與be動(dòng)詞后面的名詞一致。如上述例句。
