Unit 4 Reduce、Reuse，Recycle. (语法讲练） 复习状语从句与宾语从句 【知识讲解】 复合句是初中英语语法核心考点，其中状语从句、宾语从句为中考高频必考内容。本单元主要系统复习这两类从句。 1.状语从句 在句中起状语作用的从句叫状语从句。状语从句主要包括时间状语从句、条件状语从句、原因状语从句、结果状语从句、目的状语从句、让步状语从句、比较状语从句等。 (1)时间状语从句 引导时间状语从句的词常见的有before,after,while,when,as,since，until等。 ①在含有before(在…...之前)/after(在…...之后)引导的时间状语从句的复合句中，当主句的主语和从句的主语相同时，从句可转换为“before/after+动名词”结构。 My father often drinks a cup of tea before he goes to work. =My father often drinks a cup of tea before going to work. 我爸爸经常在上班之前喝杯茶。 ②while,when和as作连词时都可表示“当…...时”，引导时间状语从句。when可以和延续性动词连用，也可 以和非延续性动词连用：while只能和延续性动词连用。如果主句和从句的动作同时发生且都是进行时态，只能用while或as My mother was cooking when I got up yesterday morning.昨天早上我起床时，我妈妈正在做饭 I was watering the flowers while my brother was watching TV.我弟弟正在看电视时，我在浇花 ③since意为“自从”，引导时间状语从句。since引导的时间状语从句常用一般过去时，是现在完成时的标志之一。此外，还常用于“It’s+时间段+since从句.”结构中。 I haven't seen Jim since I graduated from high school. 我自从高中毕业之后就没见过吉姆。 It is 5 years since his father died.他父亲去世5年了。 ④在含有until(直到…为止)引导的时间状语从句的复合句中，主句为肯定句时，主句谓语动词用延续性动词；主句是否定句时，主句谓语动词用非延续性动词。 I watched TV until my mother came back.我看电视一直到我妈妈回来。 I can't enter the library until it opens. 直到图书馆开门了我才能进去。 (2)if(如果)unless(除非)引导的条件状语从句 在含有条件状语从句的复合句中，如果主句是一般将来时态的句子、祈使句或含有情态动词的句子，从句常用一般现在时表将来。 If it rains tomorrow,we won't go to the zoo. 如果明天下雨，我们就不去动物园。 You'll fail the exam again unless you work harder. 你如果再不加把劲，考试还会不及格。 (3)原因状语从句 引导原因状语从句的连词有because(因为)，as(由于)，since(既然)等because语气最强，since次之，as最弱它们不能与so出现在同一个句子中。 We stayed at home because it was raining. 因为正在下雨，所以我们待在家里。 (4) 含有so...that/such...that的结果状语从句 so...that,such...that意为“如此…...以至于”。常用结构有：such+a/an(+形容词)+可数名词单数+that从句：such(+形容词)+可数名词复数/不可数名词+that从句；so+形容词或副词+that从句；so+形容词+a/an+可数名词单数+that从句。 The novels are so interesting that I want to read them once again. =They are such interesting novels that I want to read them once again. 这些小说非常有趣，我想再读一遍 (5)so that和in order that引导目的状语从句 He got up early so that/in order that he could get to school on time.他起得很早以便能按时到校 (6) although/though引导的让步状语从句。 although和though意为“尽管”，用法相同，但although比though正式。although/though不能和but连用，但可以与yet/still一起使用。 Although it was raining,yet the football match still went on. 尽管下着雨，足球赛仍然继续进行。 (7)than,as引导比较状语从句 比较状语从句表达人或事物属性或特征的不同程度，表示比较、类比等，常由than,as等引导。 She earns a lot more than I do. 她赚得比我多很多 She isn't so/as tall as I. 她不如我高。 真｜题｜链｜接 (1)(山东东营中考) __________you've finished your homework,you may go out and play. A.Since B.Before C.Unless D.Although 解析：我们可用“句意分析决“解公死题since“既然；自从”：before"在……之前”；unless“除非”；although“虽然”。结合逸项可推知句意为“风然你究成了家庭作业，你就可以出去玩”。since符合语境，在此处引导原因状语从句，故选A。 真｜题｜链｜接 (2)(山东泰安中考)一Mom,shall we have supper now？ -Oh,we won't have supper_______your dad comes back.

(语法讲练） 复习状语从句与宾语从句 【知识讲解】 复合句是初中英语语法核心考点，其中状语从句、宾语从句为中考高频必考内容。本单元主要系统复习这两类从句。 1.状语从句 在句中起状语作用的从句叫状语从句。状语从句主要包括时间状语从句、条件状语从句、原因状语从句、结果状语从句、目的状语从句、让步状语从句、比较状语从句等。 (1)时间状语从句 引导时间状语从句的词常见的有before,after,while,when,as,since，until等。 ①在含有before(在…...之前)/after(在…...之后)引导的时间状语从句的复合句中，当主句的主语和从句的主语相同时，从句可转换为“before/after+动名词”结构。 My father often drinks a cup of tea before he goes to work. =My father often drinks a cup of tea before going to work. 我爸爸经常在上班之前喝杯茶。 ②while,when和as作连词时都可表示“当…...时”，引导时间状语从句。when可以和延续性动词连用，也可 以和非延续性动词连用：while只能和延续性动词连用。如果主句和从句的动作同时发生且都是进行时态，只能用while或as My mother was cooking when I got up yesterday morning.昨天早上我起床时，我妈妈正在做饭 I was watering the flowers while my brother was watching TV.我弟弟正在看电视时，我在浇花 ③since意为“自从”，引导时间状语从句。since引导的时间状语从句常用一般过去时，是现在完成时的标志之一。此外，还常用于“It’s+时间段+since从句.”结构中。 I haven't seen Jim since I graduated from high school. 我自从高中毕业之后就没见过吉姆。 It is 5 years since his father died.他父亲去世5年了。 ④在含有until(直到…为止)引导的时间状语从句的复合句中，主句为肯定句时，主句谓语动词用延续性动词；主句是否定句时，主句谓语动词用非延续性动词。 I watched TV until my mother came back.我看电视一直到我妈妈回来。 I can't enter the library until it opens. 直到图书馆开门了我才能进去。 (2)if(如果)unless(除非)引导的条件状语从句 在含有条件状语从句的复合句中，如果主句是一般将来时态的句子、祈使句或含有情态动词的句子，从句常用一般现在时表将来。 If it rains tomorrow,we won't go to the zoo. 如果明天下雨，我们就不去动物园。 You'll fail the exam again unless you work harder. 你如果再不加把劲，考试还会不及格。 (3)原因状语从句 引导原因状语从句的连词有because(因为)，as(由于)，since(既然)等because语气最强，since次之，as最弱它们不能与so出现在同一个句子中。 We stayed at home because it was raining. 因为正在下雨，所以我们待在家里。 (4) 含有so...that/such...that的结果状语从句 so...that,such...that意为“如此…...以至于”。常用结构有：such+a/an(+形容词)+可数名词单数+that从句：such(+形容词)+可数名词复数/不可数名词+that从句；so+形容词或副词+that从句；so+形容词+a/an+可数名词单数+that从句。 The novels are so interesting that I want to read them once again. =They are such interesting novels that I want to read them once again. 这些小说非常有趣，我想再读一遍 (5)so that和in order that引导目的状语从句 He got up early so that/in order that he could get to school on time.他起得很早以便能按时到校 (6) although/though引导的让步状语从句。 although和though意为“尽管”，用法相同，但although比though正式。although/though不能和but连用，但可以与yet/still一起使用。 Although it was raining,yet the football match still went on. 尽管下着雨，足球赛仍然继续进行。 (7)than,as引导比较状语从句 比较状语从句表达人或事物属性或特征的不同程度，表示比较、类比等，常由than,as等引导。 She earns a lot more than I do. 她赚得比我多很多 She isn't so/as tall as I. 她不如我高。 真｜题｜链｜接 (1)(山东东营中考) __________you've finished your homework,you may go out and play.
