【语境应用】单句语法填空。1) I enjyed the film we saw last night. It was far mre interesting than __________ (expect). 2) The players _________ (select) frm the whle cuntry are expected _________ (bring) us hnur in this summer game.
2. It’s just typical that my jurney is n ne f the ldest lines, as well as ne f the deepest. It’s the httest n the whle Tube system. 我通常上班所走的路线刚好是地铁里最老、最深的一条线。那也是整个地铁系统里最热的一条线。
本句中as well as ne f the deepest后省略lines。
此处as well as连接的是两个平行的名词短语，因为这两个平行名词短语的中心词同为lines，所以可以省略。在省略中心词时，我们既可以省略前一个名词的中心词，也可以省略后一个名词短语的中心词，因此我们也可以说：It’s just typical that my jurney is n ne f the ldest as well as ne f the deepest lines. 不过这种省略现象主要见于书面语体。
英语中的并列句也可以进行省略。一般说来， 在后句中与上文相同的成分通常会被省略。但需要注意，省略并不是随意而为的，只有当省略的词义已经出现在句中，并且在不影响句意的情况下才可以省略。
3. Sure enugh, ging dwn the stairs and nt the platfrm is like jumping int a vlcan that’s erupting. 果不其然，走下楼梯，来到站台上就像是跳进一座正在喷发的火山。erupt v. (f a vlcan) becme active and eject lava, ash, and gases (火山)爆发，喷发 break ut suddenly and vilently 突然发生
eg since the vlcan last erupted, many huses have been built in a dangerus psitin n its slpes. 自从火山上次喷发后，很多房屋建在了火山山坡上的危险地带。At the end f a ht summer, vilence erupted in the inner cities. 一个炎热的夏末，在市中心贫民区突然爆发了暴力事件。

4. This, hwever, is nthing cmpared t the train. 不过这还远远比不上车厢里面。句中的hwever是副词，表示转折，cmpared t the train是过去分词短语作状语。过去分词(短语)作状语表示的是已完成或被动的动作。其逻辑主语和句子的主语保持一致，在句中作伴随状语、时间状语、原因状语、条件状语等。 eg Translated int English, the sentence was fund t have an entirely different wrd rder. (作时间状语) 当这个句子被翻译成英语后，我们发现它有一个完全不同的语序。
He hurried t the hall, fllwed by tw guards. (作伴随状语)他匆忙去大厅，(身后)跟着两个卫兵。Grwn in rich sil, these seeds can grw very fast. (作条件状语) 如果种在肥沃的土壤里，这些种子能长得很快。

6. My ffice is nly n the third flr f the building, s quite lw. 我的办公室就在四楼，太低了。
第一句的后半部分省略了主语和谓语，即：My ffice is, 因为它们与前半部分的主语和谓语相同，如果不省略的话就会显得很啰嗦。原句 = On the third flr f the building, my ffice is quite lw.
英语中，为了使语言简洁明了、重点突出或上下文紧密相连，可以省去某些句子成分而保持句子原意不变。了解和掌握这一现象，在阅读上有助于理解，在写作上有助于用词简练、行文自然流畅。
