3、和前面的宾语有逻辑上的“主表”关系或“主谓”关系。We all found his equipment interesting. (主表关系) I saw Mary going upstairs then. (主谓关系) （四）作状语 现在分词作状语，其逻辑主语一般是句中的主语，如果不是，需在V-ing 形式前加名词或代词主格作逻辑主语。 1. 作原因状语，相当于原因状语从句。 Being ill, Mary didnt come to school yesterday. 2. 作时间状语，相当于时间状语从句。Seeing their teacher coming, the students

5、 died, leaving nothing but debts. 6. 作伴随状语或方式状语。 He sat by the roadside, begging. （五）现在分词的完成式表示它发生在主句谓语动词表示的动作之前。 Having finished his homework, he left the classroom. （六） 现在分词的被动式 当句子的主语是动作的承受者时，用V-ing 形式的被动式The factory being built now is a big one. （七） 现在分词的否定形式是由“not + 现在分词”构成。 Not having been inv

(2) He is retired. 他已退休. 3. 有些过去分词作表语时,构成的谓语很接近被动结构. (3)_The city is surrounded on three sides by mountains. 这座城市三面环山.过去分词作表语 【注

7、意】过分词作表语与被动语态的区别:过去分词作表语,主要是表示主语的状态,而被动语态则表示动作. (1) The cup was broken by my little sister yesterday. 茶杯是昨天我小妹打碎的.(是被动语态,表示动作) (2) The library is now closed. 图书馆关门了.(过去分词作表语) 【注意】过去分词表示被动或完成, -ing 形式表示主动或进行.有些动词如 interest, bore, worry, surprise, frighten 等通常用其过去分词形式来修饰人,用 -ing 形式来修饰物. (3) The book i

8、s interesting and Im interested in it. 这本书很有趣,我对它很感兴趣.过去分词作定语 作定语用的过去分词相当于形容词,其逻辑主语就是它所修饰的名词.及物动词的过去分词作定语,既表被动又表完成;不及物动词的过去分词作定语,只表完成. 1. 过去分词用作定语,如果是单个的,常置于其所修饰的名词之前. We must adapt our thinking to the changed conditions. 我们必须使我们的思想适应改变了的情况. 2. 过去分词短语用作定语时,一般置于其所修饰的名词之后,其意义相当于一个定语从句,但较从句简洁,多用于书面语中.

9、The concert given by their friends was a success.他们朋友举行的音乐会大为成功. 3.过去分词短语有时也可用作非限制性定语,前后常有逗号.

(1) Written in a hurry, this article was not so good! 因为写得匆忙,这篇文章不是很好.【注意】written 为过去分词作状语,表示这篇文章是被写的,而且已经被写. 值得注意的是,有些过去分词因来源于系表结构,作状语时不表被动而表主动.这样的过去分词及短语常见的有: lost (迷路); seated (坐); hidden (躲); stationed (驻扎); lost / absorbed in (沉溺于);

11、born (出身于); dressed in (穿着); tired of (厌烦). (2) Lost / Absorbed in deep thought, he didnt hear the sound.因为沉溺于思考之中,所以他没听到那个声音. 2. 过去分词作状语时其逻辑主语为主句的主语,此时应注意人称一致.(1) Given another hour, I can also work out this problem. 再给我一个小时,我也能解这道题.(given 为过去分词作状语逻辑主语为主句主语 I ,即 I 被再给一个小时.) (2)_ Seen from the top o

12、f the hill, the city looks more beautiful to us. 从山顶看城市,城市显得更漂亮.(seen 为过去分词作状语,表被看,由语境可知,它的逻辑主语必须是城市,而不是我们,因为我们应主动看城市.)【注意】如果过去分词作状语时,前面再加逻辑主语,主句的主语就不再是分词的逻辑主语,这种带逻辑主语的过去分词结构实际上属于独立主格结构. (1) The signal given, the bus started. 信号一发出,汽车就开动了.(the signal 是 given 的逻辑主语,因此主句主语 the bus 就不是given 的逻辑主语. (2)

13、Her head held high, she went by. 她把头昂得高高地从这儿走了过去.(her head 是 held high 的逻辑主语,因此主句主语 she 就不再是held high 的逻辑主语.) 3. 过去分词作状语来源于状语从句.(1) Caught in a heavy rain, he was all wet. 因为淋了一场大雨,所以他全身湿透了. (caught in a heavy rain 为过去分词短语作原因状语,它来源于原因状语从句 Because he was caught in a heavy rain.)(2)_Grown in rich soil
