1、謂語和謂語基本保持單復數(shù)的一致,即：主語是可數(shù)名詞單數(shù)或不可數(shù)名詞時,謂語動詞用單數(shù)形式：如：The computer was a great invention.(計算機是個了不起的發(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)做句子主語時, 如果表示整體概念,則謂語用單數(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,則謂語用復數(shù)形式,如：Class Three have a map of China.(三班有張中國地圖) 3、Chinese, Japanese, fish, sheep, people等表示單個時謂語用單數(shù),表示許多時,謂語用復數(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,但不是復數(shù),因此謂語仍用單數(shù)：The news is very exciting. (這個消息令人興奮) 5、glasses, shoes, socks, trousers, gloves等名詞往往用復數(shù)形式,故謂語用復數(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后跟名詞復數(shù)時謂語用復數(shù)形式,跟不可數(shù)名詞時謂語用單數(shù)形式。如：A lot of students are playing baseball now.(現(xiàn)在有許多學生在打壘球) A lot of time was wasted on that work.(大量的時間花在了那個工作上)(被動句) 7、and連接兩個名詞做主語時,謂語原則上用復數(shù),但是兩個名詞若構(gòu)成一個整體事物時,謂語則用單數(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. (魚和薯條是一種出名的食品) 8、 there be 句型中be的單復數(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…連接兩個事物做主語時,謂語一般用復數(shù)。如：Both you and I are required to be here tomorrow.(你和我明天要求都來) 10、主語中含有with的短語時,謂語單復數(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. (一名婦女帶著一個七歲的孩子(當時)就站在路邊)
