1、謂語(yǔ)和謂語(yǔ)基本保持單復(fù)數(shù)的一致,即：主語(yǔ)是可數(shù)名詞單數(shù)或不可數(shù)名詞時(shí),謂語(yǔ)動(dòng)詞用單數(shù)形式：如：The computer was a great invention.(計(jì)算機(jī)是個(gè)了不起的發(fā)明)The water in the glass is very cold.(玻璃杯里的水很冷)
2、集體名詞(如family, class, team, group, row, police, school等)做句子主語(yǔ)時(shí),
如果表示整體概念,則謂語(yǔ)用單數(shù)形式,如：Class Three is a very good class.(三班是好班)
如果表示其中的所有成員時(shí),則謂語(yǔ)用復(fù)數(shù)形式,如：Class Three have a map of China.(三班有張中國(guó)地圖)
3、Chinese, Japanese, fish, sheep, people等表示單個(gè)時(shí)謂語(yǔ)用單數(shù),表示許多時(shí),謂語(yǔ)用復(fù)數(shù)。如：There is a sheep in the yard.(院子里有只綿羊) / There are some sheep in the yard.(院子里有一些綿羊)
4、maths, news等雖然有s結(jié)尾,但不是復(fù)數(shù),因此謂語(yǔ)仍用單數(shù)：The news is very exciting. (這個(gè)消息令人興奮)
5、glasses, shoes, socks, trousers, gloves等名詞往往用復(fù)數(shù)形式,故謂語(yǔ)用復(fù)數(shù)。如：
The trousers are very cheap and I want to take them.(褲子很便宜,我想買)
6、a lot of后跟名詞復(fù)數(shù)時(shí)謂語(yǔ)用復(fù)數(shù)形式,跟不可數(shù)名詞時(shí)謂語(yǔ)用單數(shù)形式。如：A lot of students are playing baseball now.(現(xiàn)在有許多學(xué)生在打壘球) A lot of time was wasted on that work.(大量的時(shí)間花在了那個(gè)工作上)(被動(dòng)句)
7、and連接兩個(gè)名詞做主語(yǔ)時(shí),謂語(yǔ)原則上用復(fù)數(shù),但是兩個(gè)名詞若構(gòu)成一個(gè)整體事物時(shí),謂語(yǔ)則用單數(shù)。如：The teacher and his son are picking apples now.(老師和他的兒子在摘蘋果) / Fish and chips is very famous food. (魚和薯?xiàng)l是一種出名的食品)
8、 there be 句型中be的單復(fù)數(shù)一般由靠近的名詞決定。如：There is a table and four chairs in the room.(房間里有一張桌子和四張椅子)
9、用both…and…連接兩個(gè)事物做主語(yǔ)時(shí),謂語(yǔ)一般用復(fù)數(shù)。如：Both you and I are required to be here tomorrow.(你和我明天要求都來)
10、主語(yǔ)中含有with的短語(yǔ)時(shí),謂語(yǔ)單復(fù)數(shù)由with之前的人物決定。如：A woman with a 7-year-old child was standing at the side of the road. (一名婦女帶著一個(gè)七歲的孩子(當(dāng)時(shí))就站在路邊)
