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

最新【初中英语】一般现在时练习题人教版1 一、一般现在时 1．Before the sun ______, we need to get to the top of the mountain. A. set B. sets C. is setting D. will set 【答案】B 【解析】【分析】句意：在太阳落山之前，我们需要到达山顶。主句是将来时，在时间和条件状语从句中要用一般现在时。从句的主语“the sun” 是第三人称单数，所以set用三单形式，故答案选B。 【点评】本题考查在时间状语从句中动词的时态原则:用-般现在时代替一般将来时。 2．—Let's go climbing if it ___ tomorrow. —But nobody knows if it ___tomorrow. A. won't rain; rains B. doesn't rain; rains C. doesn't rain; will rain D. won't rain; will rain 【答案】 C 【解析】【分析】句意：——如果明天不下雨我们一起去爬山吧。——但是没有人知道是否明天会不会下雨。if引导的条件状语从句，遵循主将从现的原则，第一空，if引导条件状语从句，从句用一般现在时，第一空填doesn't rain，第二空if，是否，引导宾语从句，根据tomorrow，可知宾语从句用一般将来时，第二空填will rain，故选C。 【点评】考查情景交际。注意识记if引导的宾语从句和条件状语从句的用法。 3．— Linda has to Paris. How can I get in touch with her? — Don't worry. She will call you as soon as she there. A. been；will get B. been；gets C. gone；will get D. gone；gets 【答案】 D 【解析】【分析】句意：——琳达去巴黎了，我怎么跟她保持联系？——别担心，她一到达那里就会给你打电弧。根据I get in touch with her? 可琳达已经去巴黎了，不在说话现场，因此使用have gone 结构，答语是一个时间状语从句，时间状语从句因遵循主将从现的原则，as soon as后是从句，应使用一般现在时表将来，故答案是D。 【点评】考查have gone to与have been to的区别。注意两者意思的不同，同时要注意在时间状语从句中主将从现的原则。 4．—Jeff, could you tell me if it___ tomorrow. If it ____tomorrow, I will stay at home. —It's reported that it will be sunny, let's go camping on the Fenghuang mountain. A. rain; rain B. rains; rains C. will rain; rains D. will rain; will rain 【答案】 C 【解析】【分析】句意：——杰夫，你能告诉我明天是不是会下雨，如果明天下雨，我将呆在家里。——据报道天气将会晴朗，我们去凤凰山野营吧。第一句为if引导的宾语从

While he was doing his homework, the telephone rang. As he walked along the lake, he sang happily. He had learned a little Chinese before he came to China. After he finished middle school, he went to work in a factory. (2)在时间状语从句里，通常不用将来时态，用现在时态表示将来的动作或状态。例如： I’ll ring you up as soon as I get to New York. I will tell him everything when he comes back. He won’t believe it until he sees it with his own eyes. (3)在带有till或until引导的时间状语从句的主从复合句里，如果主句用肯定式，其含义是“一直 到……时”，谓语动词只能用延续性动词。如果主句用否定式，其含义是“直到……才……”, “在…… 以前不……”, 谓语动词可用瞬间动词。例如： The young man read till the light went out. Let’s wait until the rain stops. We won’t start until Bob comes. Don’t get off until the bus stops. 2. 条件状语从句 (1)条件状语从句通常由if, unless引导。例如： What shall we do if it snows tomorrow Don’t leave the building unless I tell you to. (2)在条件状语从句里，谓语动词通常用现在时态表示将来的动作或状态。例如： I’ll help you with your English if am free tomorrow. He won’t be late unless he is ill. (3)“祈使句 + and (or)+ 陈述句”在意思上相当于一个带有条件状语从句的复合句。例如： Hurry up, or you’ll be late. =If you don’t hurry up, you’ll be late. Study hard and you will pass the exam. =If you study hard, you will pass the exam. 3. 原因状语从句 (1)原因状语从句通常由because, since, as引导。例如： He didn’t come to school because he was ill.

(动词宾语) He aｓｋs ｈｉｍhowｌoｎｇMike ｈａs beｅｎdown . （动词宾语） Mｉss Zhaｎg is angryａｔwhaｔyｏuｓaｉｄ.
