2019高考二轮复习英语教案ampnbsp非谓语动词和独立主格结构

　　XX高考二轮复习英语教案: 非谓语动词和独立主格结构
　　【专题要点】非谓语动词和独立主格结构主要用法如下：1.动名词和动词不定式作主语、宾语；2.只跟动名词作宾语的动词或动词短语；3.只跟动词不定式作宾语的常见动词；
　　4.既可以跟动名词又可以跟动词不定式作宾语，且意义不同的动词或短语；5.不定式、现在分词、过去分词作宾语补足语的区别 ；6.不定式、现在分词、过去分词作定语时的区别；
　　7.不定式、现在分词、过去分词作状语时的区别；8.动名词的复合结构在句中作状语 ；
　　9.there be 结构的两种非谓语形式；10.独立主格结构在句中作状语；
　　11.with复合结构在句中作状语或定语。
　　【考纲要求】非谓语动词包括不定式、动词-ing形式和过去分词三种形式。动词的非谓语形式是中学英语语法的重点和难点,也是每年高考热点中的热点, 考纲要求掌握：非谓语动词的时态和语态；他们在英语句子中的作用；非谓语动词的基本用法和含义，非谓语动词在句子中可以充当多种句子成分，比如主语、宾语、宾语补足语、定语、状语、表语等；掌握非谓语动词充当相同句子成分时的辨析；掌握非谓语动词在不同的语境、语义下的运用。
　　对于独立主格结构考纲要求掌握独立主格结构的构成方式；在句子中的作用以及with复合结构。
　　【教法指引】非谓语动词包括不定式、v-ing形式和过去分词，是高中英语学习的难点，也是高考考查的重点。高中英语非谓语动词是一个重要考点，教师在引导学生复习备考中要注意重点突出、训练得当，尤其是对以下要点的复习：
　　1.不定式、现在分词与过去分词的用法区别；2.非谓语动词的主动式与被动式；3.非谓语动词完成式的用法；4.非谓语动词用作伴随状语；5.非谓语动词用作目的状语；6.非谓语动词用作结果状语；7.非谓语动词用作宾语补足语；8.非谓语动词的逻辑主语问题；9.非谓语动词用作主语的问题；10.＂(be+)过去分词+介词＂结构；11.动名词的复合结构和there be结构的非谓语动词形式。
　　对于独立主格结构的复习，教师必须要讲清它的构成方式和在句子中的作用以及与with复合结构和分词之间的辨析的关系。
　　【知识网络】 非谓语动词用法
　　非谓语动词主要包括不定式、动名词和现在分词。为了区分这三种不同的非谓语动词的用法和含义，我们将分别从三种非谓语动词在句子中做主语、宾语、宾语补足语、定语、状语、表语以及一些特殊结构句型等角度来区分其用法和细微含义。
　　1．不定式和动名词作主语的区别
　　(1)动名词作主语通常表示抽象动作；而不定式作主语表示具体动作。
　　smoz.x.x.kld一词，其后宾语只跟不定式，不能跟动名词。例如：
　　i should liz.x.x.kch, a lot 等习惯上用不定式做定语。
　　john will do anything but worz.x.x.kt shutting the door behind him.
　　他出去后将门随手关上。
　　not z.x.x.kt a word more spoken, he picked up the paper.
　　没再多说一个字，他拾起那张纸。（借此结构；表伴随）
　　6、the last guest to arrive, our party was started.
　　最后一位客人到了，我们的晚会开始了。（名词 不定式；表时间）
　　五、独立主格结构与分词短语作状语的异同：
　　1、独立主格结构与分词短语都可以转化成状语从句。但是，独立主格结构转换成状语从句后，有自己的逻辑主语，与主句 的主语不一致；而分词短语转化为状语从句后，从句的主语与主句的主语相同。例：
　　⑴ if time permit, we’d better have a rest at this weekend. － time permitting，we’d better have a rest at this weekend.
　　如果时间允许，本周末我们最好休息一下。
　　⑵ when we see from the top floor, we can find the garden more beautiful. － seeing from the top floor, we can find the garden more beautiful. 从顶楼上看，花园更漂亮。
　　2、 还应该注意，分词结构的逻辑主语不是总和主句 的主语一致，而是主句的其他成分。语法上称作＂依着原则＂；有些分词结构在句子上找不到它的逻辑主语，语法上称作＂悬垂分词＂。例：
　　⑴ looking for my watch in the room, it had taken me a long time. 在屋里找表，用了我很长时间。(依着原则)
　　⑵ when planting these flowers, care must be taken not to damage the root. (我们)种花时必须小心，不能碰坏花根。（悬垂分词）
　　六、独立主格结构与独立成分的异同：
　　1、有的 分词短语可以独立存在，在句子中没有逻辑上的主语，实际上已经成了习惯短语。这些短语有：generally speaking; frankly speaking; judging from; supposing等等。
　　例：
　　⑴ generally speaking, the rule is very easy to understand.总的来说，这个规则很容易懂。
　　⑵ judging from what he said, she must be an honest girl. 根据他所说的，她一定很诚实。
　　2 、有些固定短语是带to的不定式，表明说话人的立场和态度，在句中作独立 成分。这些短语有：to be honest; to be sure; to tell you the truth; to cut a long story short; to be frank; to make the matter worse等等。例：
　　⑴ to tell you the truth, what i said at the meeting was not my opinion. 说实话，我在会上说的并不是我的意见。
　　⑵ to make the matter worse, he locked his keys in the car. 更糟糕的是，他把钥匙锁在车里了
　　七、非谓语动词独立主格结构
　　在独立主格结构中，非谓语动词和它前面的名词或代词存在着逻辑上的主谓关系。
　　such an able man to help you，you will surely succeed sooner or later.
　　有这么能干的人来帮你, 你迟早一定会成功的。（such an able man和 to help you 之间存在着主谓关系）
　　= since such an able man will help you, you will surely succeed sooner or later.
　　he seating himself at the desk, his mother began to tell him a story.
　　他在书桌旁坐好后，他母亲开始给他讲故事。（seating himself at the desk拥有了自己的逻辑主语he，注意是＂主格＂）
　　= when he seated himself at the desk, his mother began to tell him a story.
　　the key to the bike lost, he had to walk to school.
　　由于丢了自行车钥匙，他只好步行去学校。（lost 的逻辑主语是the key，lost 也可以用完成式having been lost）
　　= because the key to the bike had been lost, he had to walk to school.
　　a．不定式＂独立主格结构＂
　　在＂逻辑主语+动词不定式＂结构中，动词不定式和它前面的名词或代词存在着逻辑上的主谓关系。这种结构也可用一个从句或并列分句来表达。
　　1．动词不定式用主动的形式
　　在独立主格结构中，动词不定式和它前面的名词或代词存在着逻辑上的主谓关系。
　　his mother to come tonight，he is busy preparing the dinner.
　　他母亲今晚要来,他正在忙着准备饭菜。（= as his mother is to come tonight, he is busy preparing the dinner.）
　　——will you go to the concert tonight 你今晚去听音乐会吗？
　　——sorry. so many exercise-books to check, i really can＂t afford any time.
　　对不起，有这多的作业要批，我真的抽不出时间。
　　（ because i shall check so many exercise-books tonight ,i really can＂t afford any time.）
　　the four of us agreed on a pision of labour , each to translate a quarter of the book.
　　我们四人同意分工干，每人翻译全书的四分之一。
　　（ the four of us agreed on a pision of labour and each is to translate a quarter of the book.）
　　many trees,flowers,and grass to be planted, our newly-built school will look even more beautiful. 种上许多的树，花和草后，我们新建的学校将看上去更美。(=if many trees,flowers,and grass are planted,our newly-built school will look even more beautiful.)
　　b．-ing形式＂独立主格结构＂
　　动词的-ing形式 作状语时，其逻辑主语一般应与句子的主语保持一致。
　　being ill, he went home.
　　由于生病,他回家了。（= as he was very ill, he went home.）
　　seating himself at the desk, he began to read a magazine.
　　在课桌旁坐好后，他开始看杂志。（= when he had seated himself at the desk, he began to read a magazine.）
　　1． 表示时间的-ing形式作＂独立主格结构＂
　　everyone being ready, the teacher began his class.
　　每个人都准备好后，老师开始上课。（相当于一个时间状语从句when everyone was
　　ready)
　　the chairman began the meeting , everyone being seated.
　　每个人坐好后，主席开始开会。（相当于一个时间状语从句after everyone was seated）
　　2． 表示原因的-ing形式作＂独立主格结构＂
　　the boy leading the way, we had no trouble finding the strange cave. 由那个男孩带路，我们没有困难就找到了那 奇怪的洞。（相当于一个原因状语从句because the boy led the way）
　　many eyes watching him, he felt a bit nervous. 许多眼睛看着他，他感到有点儿紧张。（相当于一个原因状语从句as many eyes were watching him）
　　必背：
　　含有being的独立主格结构。

　　= as it is national day today, the streets are very crowded.
　　there being no further business to discuss, we all went home. 没有别的事可讨论，我们都回家了。

　　my health allowing, i will work far into the night.
　　我的健康许可的话，我愿工作到深夜。（相当于一个条件状语 从句if my health allows）
　　4． 表示方式的-ing形式作＂独立主格结构＂
　　the students are walking in the school happily, each wearing a card in front of his chest.
　　学生们快乐地在学校里走着，每个人胸前都带着一张卡。（相当于一个并列分句and each wears a card in front of his chest）
　　the boy lay on the grass, his eyes looking at the sky.
　　男孩躺在草地上，眼睛看着天空。（相当于一个并列分句and his eyes were looking at the sky）
　　c．-ed形式＂独立主格结构＂
　　与逻辑主语+动词的-ing形式一样，如果-ed形式的逻辑主语和句子的主语不一致的话，就需要用-ed形式的独立主格结构。
　　the book written in simple english, english beginners were able to read it.
　　该书是用简单英语写的，英语初学者也能看懂。
　　= as the book was written in simple english，english beginners were able to read it.

　　the task completed, he had two months＂ leave.
　　任务完成以后，他休了两个月的假。（=when the task had been completed, he had two months＂ leave.）
　　比较：
　　动词不定式表示动作没有发生或即将发生，动词-ed形式表示动作已经结束，动词-ing形式往往表示动作正在进行。
　　the manager looks worried，many things to settle. 经理看上去很着急, 有这么多的事情要处理。（事情还没有处理，而且是由经理本人来处理，用不定式to settle）
　　the manager looks relaxed, many things settled. 许多事情已经处理好了， 经理看上去很轻松。（事情已经处理好了，用动词-ed形式settled表示动作已经结束）
　　the food being cooked, the boy was watching tv. 小孩一边做饭，一边看电视。（两个动作同时进行）
　　the food cooked, the boy went to bed. 饭做好了，小孩去睡了。（两个动作有先后，饭已做好，小孩才去睡觉的
　　八、 with、without 引导的独立主格结构
　　介词with/without +宾语+宾语的补足语可以构成独立主格结构，上面讨论过的独立主格结构的几种情况在此结构中都能体现。
　　a． with+名词代词+形容词

　　九、独立主格结构的句法功能
　　独立主格结构在句中除了能充当原因状语、时间状语、条件状语和伴随状语外，还能作定语。在形式上，＂独立主格结构＂可位于句首、句中或句尾，并通常用逗号与主句隔开。
