初中英语语法讲解 在中考单项选择试题中，除了时态，名词的考查频率也较高。一般考查以下几点： 一、可数名词与不可数名词 在可数名词与不可数名词上一般出现这样几类，（1）分辨是哪一类名词，并根据结论做选择。（2）可数名词复数的不规则变化。（3）不可数名词的量化表达。所以，考生首先要能够明确哪些是可数名词，哪些是不可数名词。其次，还要知道可数名词的复数的变化规则。可数名词的变化规则一般是在单词后面加-s 或-es，如： 1desk---desks bed---beds piano---pianos hat---hats bag---bags photo---phot os 2bus---buses box---boxes watch---watches brush---brushes 3tomato---tomatoes potato---potatoes hero---heroes Negro---Negroes 4 leaf---leaves knife---knives 5baby---babies family---families 另外，还要记住一些特殊的名词的变化形式，如： Chinese---Chinese Japanese---Japanese Englishman---Englishmen Frenchman---Frenchmen Russian---Russians American---Americans

German --- Germans child---children foot---feet man---men woman---women tooth---teeth goose --- geese deer---deer sheep---sheep 还要掌握不可数名词的量化表达有：a piece of、a bag of、a bottle of、a cup of、a glass of 另外，大家应注意：单数集合名词作主语时谓语动词“数的”变化：单数集合名词如class, police, family, school, group, team等。尽管形式上是单数，意义上都是复数，因此，一般要与复数谓语动词连用，例如： Class Five have a foreign friend. 五班有一位外国朋友。（这里的五班指五班的同学的。） His family are good to me. 他的家人对我很好。（很显然，这里的family指家庭成员。）当上述集合名词着重指“整体”时，意义上则是单数，因此，要与单数谓语动词连用。例如， Our school team often plays well in our city. 我们的校队经常在我们市踢得很好。（这里的team 指整个队，但意义上仍为单数，故谓语动词用plays. 初中英语语法讲解二、名词所有格 名词所有格有两种形式：一是加’s，一种是用of来表示。一般情况

初中英语语法大全：therebe句型讲解

There be句型的基本用法是表示“某地（或某时）有某人（或某物）”，其形式为“Therebe+代词或名词（短语）+地点/时间状语”。这里there是引导词，没有词义，be是谓语动词，代词或名词（短语）是主语。be要与主语保持人称和数的一致。否定句是在be后加not；一般疑问句是将be放在句首；反意疑问句中的简短问句是由“be（或其否定式）+there”构成。例如： is a desk and two chairs in the room.（紧挨着be动词的主语是a desk，是单数，故be的形式要用is） aren't two chairs and a desk in the room.（否定句） there anything wrong with your ears（Yes，there is./No，there isn't.） wasn't a meeting yesterday，was there（反意疑问句） 除此之外，还有一个重要句式“有某人在做某事”，要用“There be +sb.+doing sth.+地点/时间状语”。例如： There are several children swimming in the river.河里有几个孩子在游泳。 There be 结构中常见的时态有如下几种情况： 通过上表可知：各种时态的变化是通过 be动词的变化来体现的。至于你提到的两个句子我们先不考虑对错，首要的问题是弄清楚There be与have所表示的意义。There be句型表示“存在”关系，have表示“所属”关系，两者不能混合在一个句子中。例如，要说“明天有一个班会。”（1）There will have a class meeting tomorrow.（×）（2）There is going to/will be a class meeting tomorrow.（√）有时候既表示“存在”又表示“所属”时两种都可以用。例如：Class Three have a map of China on the wall.（“地图”为三班学生所有）There is a map of China on the wall in Class Three.（“地图”存在于三班）由此看来，There will have是错误的。 复习There be句型时除了掌握基础知识外，还应注意以下问题： be句型的考查更多的是将be动词与主语结合在一起进行的，即主谓的一致性。例如： （1）There is _____ on the floor.
