高考英语专题复习主谓一致(附答案)I. 考点分析一、概述主谓一致是指句子成分之间或词语之间在人称、性、数等方面的一致关系。

处理主谓一致一般应遵循以下三条原则:1. 语法一致,即在语法形式上取得一致。

例如,主语为单数形式,谓语动词也为单数形式;主语为复数形式,谓语动词也采取复数形式。

a. The number of errors was surprising.b. Julia and her twin sister naturally look a lot alike.2. 意义一致,即从意义着眼处理一致关系。

a. The crowd were fighting for their lives. ( 单形名词主语要求复数谓语动词,下划线部分表示一个整体中的成员)b. Five minutes is enough. ( 复数名词单数谓语动词,下划线部分表示一个数目)3. 邻近原则,即指谓语动词的形式与邻近的名词一致。

a. A man of abilities are needed.(动词are不与主语a man一致,而与其邻近的复形名词abilities 形式上一致。

二、主谓一致注意要点:1. 当名词词组中心词为表示度量、时间等复数名词时,往往可根据意义一致的原则,把这些复数名词看作一个整体,谓语动词采取单数形式。

a. The dollars is not enough.b. Three months passes in no time at all on the ranch.如果明显地指一个个个体,则要根据语法一致地原则,谓语动词用复数形式。

a. There are two sliver dollars in each of the stockings.2. 如果名词词组中心词是all, most, half, the last, the rest, the remainder等词组时,其主谓关系一般遵循意义一致的原则:如所指为复数意义,谓语动词用复数形式;如所指为单数意义,则谓语动词用单数形式。

高考英语主谓一致练习题20题(带答案)

高考英语主谓一致练习题20题(带答案)1. In the library, there ____ a large number of books on various subjects.A. isB. areC. hasD. have答案解析:B。

本题考查的是存在句中的主谓一致。

“a large number of + 复数名词”表示“许多”,作主语时,谓语动词要用复数形式。

A选项“is”用于单数主语;C和D选项“has”和“have”表示“拥有”,这里是存在句,不是表示所属关系,所以不选。

2. Not only the students but also their teacher ____ going to the museum tomorrow.A. isB. areC. wasD. were答案解析:A。

本题考查的是主谓一致中的就近原则。

“not only...but also...”连接两个并列主语时,谓语动词与靠近它的主语保持一致。

在这个句子中,靠近谓语动词的主语是“their teacher”,是单数,再根据“tomorrow”可知是一般将来时,这里用“be going to”结构,所以选“is”。

B选项“are”用于复数主语;C和D选项“was”和“were”是一般过去时,不符合句子时态。

3. The number of people who ____ interested in this new product ____ increasing.A. are; isB. is; areC. are; areD. is; is答案解析:A。

“the number of + 复数名词”表示“……的数量”,作主语时,谓语动词用单数形式,所以第二个空填“is”;“who”引导的定语从句修饰“people”,“people”是复数,所以从句中的谓语动词用“are”。

B选项主谓一致判断错误;C选项两个空都错误;D选项第一个空错误。

两个或更多由a病率,如果没有得到及时的控制,会引发很多的颈椎病并发症,那么颈椎病的并发症有哪些呢? 颈椎病的并发症有哪些呢? 吞咽障碍:吞咽时有梗阻感、食管内有异物感,少数人有恶心、呕吐、声音嘶哑、干咳、胸闷等症状。这是由于颈椎前缘直接压迫食管后壁而引起食管狭窄,也可能是因骨刺形成过速使食道周围 生刺激反应所引起。 视力障碍:表现为视力下降、眼胀痛、怕光、流泪、瞳孔大小不等,甚至出现视野缩小和视力锐减,个别患者还可发生失明这与颈椎病造成自主神经紊乱及椎——基底动脉供血不足而引发的大脑 中枢缺血病损有关。 颈心综合征:表现为心前区疼痛、胸闷、心律失常(如中搏等)及心电图ST段改变,易被误诊为冠心病。这是颈背神经根受颈椎骨刺的刺激和压迫所致。 高血压颈椎病:可引起血压升高或降低,其中以血压升高为多,称为“颈性高血压”。由于颈椎病和高血压病皆为中老年人的常见病,故两者常常并存。 胸部疼痛:表现为起病缓慢的顽固的单侧胸大肌和疼痛,检查时有胸大肌压痛。这与颈6和颈7神经根受颈椎骨刺压迫有关。 下肢瘫痪:早期表现为下肢麻木、疼痛、跛行,有的患者在走路时有如踏棉花的感觉,个别患者还可伴有排便、排尿障碍,如尿频、尿急、排尿不畅或大小便失禁等。这是因为椎体侧束受到颈骨 或压迫,导致下肢运动和感觉障碍所致。 猝倒:常在站立或走路时因突然扭头出现身体失去支持力而猝倒,倒地后能很快清醒,不伴有意识障碍,亦无后遗症。此类病人可伴有头晕、恶心、呕吐、出汗等植物神经功能紊乱的症状。这是 增生改变压迫椎动脉引起基底动脉供血障碍,导致一时脑供血不足所致。注意事项 颈椎病并发症都有哪些呢?上面这些就是颈椎病的并发症,由此可看出颈椎病的危害还是很大的,一旦发现颈椎病的症状,应该及时去。 练字加盟
