▪ The next day was clear and mild, they were pleased t see the beautiful muntains lking ut ver the city. (Para. 1)
▪ Fr bth f them, the thught f crssing the whle cuntry by rail was exciting. (Para. 1)
当过去分词和现在分词作表语时，过去分词描述人或物的情感，意为：_________；现在分词描述事物，意为：_________
▪ Seen frm the train windw, the muntains and frests f Canada lked massive. (Para. 2)
▪ Lking at the beautiful scenery, they bth agreed that it was the mst awesme jurney they had ever taken. (Para. 2)
群山和森林作为“物”是“被看到”的
they 指“人”，人是动作“看” 的主体
1. 过去分词作表语的用法。过去分词可放在连系动词be, get, feel, remain, seem, lk, becme等之后作表语，表示主语所处的状态。He lked wrried after reading the letter.看完信后，他显得很忧虑。When we heard f it, we were deeply mved.当我们听说了这件事，我们深受感动。
2. 感觉类及物动词的现在分词与过去分词作表语的区别。英语中有很多与感觉有关的及物动词，其现在分词表示主动意义，即“令人有某种感觉的”，多用来修饰物；其过去分词含有被动意义，即“人被引起某种感觉的”，多用来指人、人的声音、笑容或表情等。常用的这类词有：
surprising 令人吃惊的surprised 感到吃惊的
frightening 令人害怕的frightened 感到害怕的
discuraging 令人泄气的discuraged 泄气的
disappinting 令人失望的disappinted 感到失望的
1. 过去分词(短语)作状语，表示被动的或完成的动作，这时句子的主 语和过去分词之间为逻辑上的被动关系。Written in a hurry, this article was nt s gd.因为写得匆忙，这篇文章不是很好。本句中的written in a hurry为过去分词短语作状语，表示这篇文章是被写的，而且已经被写完。过去分词通常在句中作时间状语、原因状语、条件状语、让步状语、方式状语和伴随状语等。
注意：过去分词(短语)作状语时，前面有时可以加上when，if，while，thugh，even if，until，unless等连词，这种结构可以看作是一种省略的状语从句(省略部分多为“主语＋be的多种形式”)。需要注意的是，省略的主语必须和主句的主语相同或为it。Even if invited(＝Even if I’m invited), I wn’t take part in the party.即使受到邀请，我也不会参加这个聚会的。
拓展：部分过去分词来源于系表结构，作状语时不表示“被动关系”，其前不用being。这样的过去分词及短语常见的有：lst in(陷入某种状态)、seated(坐着的)、hidden(躲着)、lst/absrbed(沉溺于)、dressed in(穿着)、tired f(厌烦了)等。 Lst/Absrbed in deep thught, she didn’t hear the sund.由于陷入沉思，所以她没有听到那个声音。Dressed in a new dress, she lks very beautiful.穿着一件新衣服，她看上去很漂亮。
2. 过去分词作状语时的位置。过去分词作条件、原因及时间状语时，通常放在句首；作伴随、结果状语时，通常放在句末；作方式状语时，一般放在句末，有时也放在句首；作让步状语时，一般放在句首，有时也放在句末。Tld that his mther was ill, Li Lei hurried hme quickly.(原因状语)得知母亲生病了，李雷迅速赶回了家。The ld man walked int the rm, supprted by his sn.(方式状语)老人在儿子的搀扶下走进了房间。
3. 过去分词与现在分词作状语的区别。过去分词与句子的主语之间存在逻辑上的动宾关系，即表示被动；现在分词与句子的主语之间存在逻辑上的主谓关系，即表示主动。助记　分词作状语记忆口诀分词作状语，主语是问题。前后两动作，共用一主语。主语找出后，再来判关系。主动用-ing，被动用-ed。Used fr a lng time，the bk lks ld.(动宾关系)由于用了很长时间，这本书看上去陈旧。注意：无论是现在分词还是过去分词，其逻辑主语必须和句子的主语一致。如果不一致，则必须用状语从句、独立主格结构等其他表达形式。
三、特殊结构：独立主格
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。)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。)
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。
