中考英语作文复合句How to Protect the Environment。

Nowadays, with the rapid development of industry and urbanization, the environment has been seriously polluted.It is high time that we took some effective measures to protect our environment.Firstly, we should make efforts to reduce air pollution. Factories should be equipped with advanced equipment to purify waste gas before discharging it into the air. Moreover, we should encourage people to use public transportation instead of driving their own cars, which can help reduce the emission of carbon dioxide.Secondly, we should pay attention to water pollution.It is reported that a large amount of industrial waste is discharged into rivers and lakes every day. As a result,the water becomes undrinkable and fish die. Therefore, we must take strict measures to control the discharge ofindustrial waste and punish those who violate the environmental protection laws.Thirdly, we should take measures to protect the wildlife. The destruction of forests has caused the loss of habitats for many animals. Therefore, we should take actions to protect the natural habitats of animals and prevent them from becoming extinct.In addition, we should raise people's awareness of environmental protection. Schools should include environmental protection education in their curriculum, and the government should organize various activities to promote environmental protection.In conclusion, protecting the environment is everyone's responsibility. We should take actions to reduce air and water pollution, protect the wildlife, and raise people's awareness of environmental protection. Only in this way can we create a beautiful and harmonious environment for future generations.。

如：While the grandparents love the children, they are strict with them.(爷爷奶奶们很爱孩子,同时对他们也严格要求。

) / It seemed as if the meeting would never end.(看起来会议没完没了。

) / Hurry up, or (else) you'll be late.(快点, 要不然就来不及了。

2020年中考英语语法复习：从属连词与复合句

2020年中考英语语法复习：从属连词与复合句做句子成分的句子叫从句，做什么成分就叫什么从句；任何从句的语序都是陈述语序。

（一）状语从句一个句子作另一个句子的状语叫状语从句。

状语从句放在主句的后面，如果强调状语，状语从句也可以放在主句的前面，用逗号与主句隔开。

1.时间状语从句：1).引导词：before, after, as, when, while, since, not…until, as soon as和once等。

2).时态：(1).before, after, when, not…until, as soon as引导的时间状语从句，如果事情没有发生用“主将从现”（“主将”有三种表现：(a).“will+动词原形”的一般将来时。

(b).祈使句(c).含有情态动词的一般现在时）；如果事情发生了就用“主过从过”（“主过”有两种表现：(a).一般过去时(b).现在完成时）如：a). I’ll write to you as soon as I get to Beijing. 我一到北京就给你写信。

（主将从现）b). Tell her about it when/before/after she comes back. 当她回来时/之前/之后告诉她。

（主将从现）c). I can’t go home until I finish my homework. 直到完成作业我才回家。

中考英语专题--复合句(解析版)

中考英语专题复合句☞考点解读通过分析各地中考试题可以看出，复合句是中考必设考点，题型多样，考查内容涵盖初中阶段常见的宾语从句、定语从句与状语从句，常涉及单项选择题、完形填空、阅读理解中句式结构的分析与理解、复合句在书面表达中的写作运用等方面，考查点主要涉及以下几个方面：1. 复合句的概念及从句类型的辨识；2. 宾语从句的连接词、语序及时态搭配；3. 宾语从句的简化及否定前移；4. 状语从句引导词的词义辨析及主从句时态的搭配；5. 定语从句关系代词或关系副词的选择。

☞考向突破1. 什么是(主从)复合句？主从复合句就是由从属连词把两个或两个以上的简单句连接而成的句子。

试比较复合句与并列句的不同：公式1：主从复合句＝简单句1（主句）＋从属连词＋简单句2（从句）公式2：并列句＝简单句1＋并列连词＋简单句2想一想：区分复合句与并列句的关键是什么？【答案】连词类型的不同。

并列句由并列连词连接而成；复合句由从属连词连接而成。

2. 初中阶段常见的复合句主从复合句中，主句是句子的主体，从句只充当主句的某个成分，不能脱离主句而存在。

简单地讲，从句在主从复合句中担当主句什么成分就叫什么从句。

在主从复合句中，担当主句宾语的句子称为宾语从句，常位于及物动词、介词或复合谓语之后，分为三类：动词的宾语从句，介词的宾语从句和形容词的宾语从句。

在主从复合句中，担当主句状语的句子称为状语从句，常用来修饰主句中的动词、形容词、副词或整个句子，起到副词的作用。

在主从复合句中，担当主句定语的句子称为定语从句，常用来修饰主句中的名词或代词，起到形容词的作用。

各地中考时常涉及宾语从句、状语从句和定语从句的考查。

3. 宾语从句宾语从句隶属于复合句，在复合句中担当宾语，常放于主句之后，即：主句动词/介词+宾从。

考点1：连接词(1) 从属连词that引导的宾语从句由陈述句转化来的宾语从句通常添加引导词that。

that没有实际意义，不翻译，只起连接作用，也不在宾语从句中充当任何成分，可省略。

2020考研英语：复合句的结构解析

2020考研英语：复合句的结构解析考研英语有许多题目组成，方便大家及时了解，下面由出国留学网小编为你精心准备了“2020考研英语：复合句的结构解析”，持续关注本站将可以持续获取更多的考试资讯! 2020考研英语：复合句的结构解析复合句，又称“主从复合句”，就是指多件事之间由于重要性的不同，分为“主句”和“从句”。

从句前一般有连接词引导（特殊情况可以省略）。

名词性从句，是指一个句子当做名词来使用，放到另一个句子之中。

常常在句子中间主要作四种成分：宾语、表语、主语、同位语。

无论以上哪一个从句，在做从句时都遵循着：连接词+陈述句，这一公式。

另外，宾语从句中that不作成分时常常被省略，但是其他几个从句都不能省略。

表语从句常接在系动词（be动词）后，毕竟系表结构。

主语从句有两种特别重要且常用的句型模板： is done + 主语从句（表达人们对一件事的观点和看法） is + adj./n. + 主语从句（表达一件事的评价）同位语从句是用来解释说明一个抽象名词，在句中位于抽象名词后。

常见抽象名词：idea， opinion， fact， evidence， question， doubt， reason， theory， belief， possibility， chance， hope， contention， guarantee等。

定语从句是修饰限定名词，先行词n. + 关系词 + 陈述句。

关系词在定语从句中作宾语时（及物动词的并与或介词后的宾语），都可以省略。

在状语从句的从属连词中，as一词多义需要注意。

并且，只要as后引导的是完整的句子，那么它引导的一定是状语从句。

主从复合句典型例句

主从复合句典型例句主从复合句典型例句如下：主从复合句是由一个主句和一个（或一个以上）的从句构成的。

主句作为句子的主体，从句只能作句子的一个次要成分，不能独立成为一个句子。

从句通常由关联词引导，并由关联词将从句和主句联系在一起。

从句按其在复合句中的作用，分为主语从句、表语从句、宾语从句、定语从句和状语从句等。

所谓并列复合句，就是由并列连词把两个或两个以上互相独立的分句连接而成的句子叫做并列句，并列句之间有并列、转折、选择、因果等关系。

知道了定义之后，我们初步可以清楚，主从复合句是由主句和从句构成的，而并列复合句则是由两个或两个以上相互独立的分句构成的。

接下来，我们用实际句子进行进一步理解。

例句：After the 1870's, a number of important authors began to reject the romanticism that had prevailed immediately following the Civil War of 1861-1865 and turned instead to realism.解析：并列复合句的定义是，两个或者以上的子句之间是并列关系，在这个句子当中，只有一个主语，那就是“a number of important authors”，也就是只有一套主谓结构，也就是只有一个子句，所以这个句子是主从复合句。

比如，I am a teacher and love gym. 这是一个主谓结构，只有一个主语，这就是主从复合句；但是，I am a teacher and I love gym. 这是两套主谓结构，连接词“and”前后有两个主语,，所以这个句子才是并列复合句。

1. 并列复合句定义：并列复合句含有两套或者更多相互并列的主谓结构的句子。

(1) Water has weight; air has weight too, but it is very light.(2) Heat is energy, so is electricity.2. 主从复合句定义：含有两套或更多的主谓结构，其中有一个是主要的主谓结构，其他主谓结构从属于它并且担任起句子成分。
