A.one third; have B.one thirds; have C.one third; has D.first three; has 【答案】A 【解析】 试题分析:句意:-妈妈,三分之一的苹果已经坏了。-我们最好尽快吃了。在英语中的分数,分子用基数词,分母用序数词,当分子大于一时,分母要用复数形式。所以选A。 考点:考查分数及主谓一致。 2.Not only his friends but also he ________ always interested in science fiction. A.show B.shows C.are D.is 【答案】D 【解析】 【详解】 句意:不仅他的朋友,而且他总是对科幻小说感兴趣。考查主谓一致。not only…but also连接两个主语的时候,谓语动词的数由离其最近的主语来决定,即就近原则,所以此处要根据he来确定谓语动词的形式;因为后面是interested in,所以用be interested in“对…感兴趣”,所以谓语动词用is;故答案选D。 3. students in our class going to the summer camp in Beijing next week. A.Two fifths; is B.Second fifths; are C.Second fifths; is D.Two fifths; are 【答案】D 【解析】 【详解】 句意:我们班五分之二的学生打算下周去北京参加夏令营。 表达分数时,分子用基数词,分母用序数词,因此五分之二的表达应该是two fifths,排除B,C;分数后面的名词为复数名词students,根据主谓一致的原则,只能用are,故答案选D。 【点睛】

主谓一致用法总结

主谓一致 使用主谓一致时,必须遵循三个原则,即语法一致原则、意义一致原则和就近一致原则。 一、当单数可数名词、不可数名词、复合不定代词、单个不定式(疑问词+不定式)、动名词或主语从句以及表示“时间、价值、重量、距离、书名、影片名称”等名词作主语时,谓语动词通常用单数形式。例如: The curtains are closed and the living room is dark when Mom and Dad enter. Visiting a place like this is always very interesting. Why pleasant smells do not reduce pain in men is a question still to be answered by scientists. 二、all(some, a lot, plenty, any, part, the rest, most等)+of+名词作主语以及分数、百分数构成短语作主语时,谓语动词单复数形式取决于of后的名词或代词。表示复数概念用复数;表示单数概念用单数。例如: As a result of the serious flood, two-thirds of the buildings in the area need repairing. One study says that 90% of our time is spent watching television

or using computers. While the rest of the passengers were getting out, she glanced at the faces around her. 三、在“名词/代词+介宾结构+谓语+…”结构中,谓语动词与名词/代词保持一致,介宾结构看作插入成分。该结构中的常见介词及介词短语有with, together with, along with, as well as, like, but, except, besides, including等。例如: Healthy eating along with regular exercise is probably the only way to become fit. Nobody but Tom and his father has ever been there. 四、a number of / a group of / a variety of / a total of 等构成短语作主语时,谓语动词用复数形式;而the number of / the group of / the variety of / the total of 等构成短语作主语时,谓语动词用单数形式。例如: The low number of attacks that happen every year proves that sharks do not feed on humans if they have the choice. Nowadays, a large number of women, especially those from the countryside, work in the clothing industry. 五、quality / pair / amount等构成短语作主语时,谓语动词根据
