2010高考二轮复习英语教案 - 专题八-非谓语动词和独立主格结构

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,
