2020届二轮复习状语从句考点讲练课件（33张）

第五讲　状语从句 第一课时　知识过关课 1 ．在时间状语或条件状语从句中，通常用一般现在时代替一般将来时，用现在完成时代替将来完成时。 2 ．辨析： when ， while ， as 引导时间状语从句。 while 必须与延续性动词连用，强调主句动作延续到从句所指的整个时间时，只能用 while ；表示 “ 随着 ” 只能用 as ；表示有规律的 “ 每当 ” 时或主句动作与从句动作有先后时，只能用 when 。 3 ．辨析： because ， since ， as 引导原因状语从句。 because 语气最强，表示直接的原因，是说话人认为对方不知道的原因，它引导的从句通常位于主句之后；在回答 why 时，或者在强调结构中，只能用 because 。 since 和 as 是对大家已知的事实提供理由或背景，它们引导的从句多位于主句前，有时也位于主句后。 4 ． as 引导让步状语从句时，从句中的状语、表语或动词必须置于句首； though 引导让步状语从句时，这些成分可置于句首也可用正常语序；但 although 等其他词引导的让步状语从句不能将这些成分前置。 5 ．表示 “ 虽然 ” 的连词 though/although 不能与表示 “ 但是 ” 的连词 but 连用；表示 “ 原因 ” 的 because 等连词不可与表示结果的连词 so 等同时使用。 读语篇，悟语法。反复朗读下列短文，领悟画线黑体部分。思考：有多少种状语从句？下面的状语从句各属于哪一种？有哪些特殊的用法？ My mother was cooking in the kitchen while [1] I was doing my school assignments. As soon as [2] I finished my homework, I went to get some water to drink. Then the doorbell rang. However, my sister unlocked the door before [3] I could open it.We were surprised the moment [4] we saw her because [5] her clothes and face were terribly dirty.She looked much poorer than [6] we expected. Since [7] we didn ’ t know what had happened to her, we stood there and waited for my sister ’ s story. We wouldn ’ t leave unless [8] my sister told us all about it. After [9] my sister got changed, she told us that she fell into a ditch when [10] she walked on a path on her way to my uncle ’ s home in the countryside. She couldn ’ t get out of the ditch. Although [11] she cried for help, no one could hear her. She tried to climb out of it, but, however [12] hard she tried, she failed to escape from it. As [13] time went by, she got worried. After several vain attempts she had to stand where [14] she was and waited until [15] a boy student passed by and gave her a hand. The boy reached her a long rope and told her to climb with the rope. She did as [16] the boy told, so that [17] she came out. My sister also warned us to be careful when [18] walking on a path even though/if [19] we are in a great hurry. That ’ s true. We should mind our step so that [20] we can ensure our safety. 1 ．用于对比两件事，意思是 “ 而 ……” 用 while ，不能用 when/as 代替。 2 ． as soon as 引导时间状语从句，表示 “ 一 …… 就 ……” 。 3 ． before 表示 “ 还没来得及就 ……” 。 4 ．名词词组如 the moment/the second/the day/the first time/next time... 等可以用来引导时间状语从句。 5 ．引导表示原因的从句时用 because ，其引导的原因状语从句一般放在主句之后，而如果只是名词性短语表示原因，则用 because of 引导。 6 ．在表示比较时，用 than 来引导比较状语从句， than 也可以作介词。 7 ．对大家已知的事实提供理由或背景时，常用 since 引导，意思是 “ 既然 ” 。其引导的从句多在主句之前。 8 ．引导条件状语从句， unless ＝ if...not ，是 “ 除非，如果不 ” 之意。 9 ． after/before 引导表示时间先后的状语从句，根据实际表达需要选用其一。 10 ． when 引导表示 “ 当 …… 时 ” 的时间状语从句。 11 ．引导让步状语从句时，可以用 although 或 though ，主句可以与副词 still 连用，但不能再与连词 but 连用了，一个复合句只需一个连词。当是 as 引导让步状语从句时，从句中的状语、表语或动词置于句首。 12 ． however 引导让步状语从句时，其后常接形容词或副词，用于修饰该形容词或副词， wherever ， whenever 也可以引导让步状语从句，在从句中作状语，相当于 no matter how/where/when ；另外 whatever ， whoever ， whichever 也可以引导让步状语从句。 13 ．表示 “ 随着 ” 时，只能用 as 引导。 14 ．引导地点状语从句时，用 where/wherever ，表示 “ 在 …… 的地方 ” 。 15 ．固定用法 “ 直到 …… 才 ……” 可以用两种表达形式： “ 延续性动词＋ until ＋句子 ” ( 用肯定形式 ) ； “ not ＋短暂性动词＋ until ＋句子 ” ( 用否定形式 ) 。 16 ．引导方式状语从句时，可以用 as ，意思是 “ 按照，像 …… 那样 ” 。 17 ． so that 引导结果状语从句，从句表示的通常是某件事的结果。 18 ． when 引导表示 “ 当 …… 时 ” 的时间状语从句时，如果主句的主语和从句的主语是一致的，可以省略 when 从句的主语和 be 动词，用分词来表示。 19 ．表示 “ 即使，尽管 ” 的 even though/if 引导让步状语从句。 20 ． so that 除了引导结果状语从句外，还可以引导目的状语从句，常与情态动词 can/could 等连用。 Ⅰ . 单句填空 ( 用适当的从属连词填空 ) 1 ． ________ hard you try, it is very difficult to lose weight without cutting down the amount you eat. 2 ． —Did Jenny return early last night? —Exactly.
