4. Nowhere else in the world can there be such a quiet , beautiful place . 世界上再没有这样优美、恬静的的放了。
〖释疑〗此句是倒装句。正常语序是：There is nowhere else in the world as quiet and beautiful as this place . 如果 nowhere 不放在句首，句子就不倒装。
当含有否定意义的副词或者连词放在句首时句子用倒装。这类词有：hardly , never , not , neither , not only … but also , little , nowhere , not a single , scarcely , barely , at no time , not once , in no time 立即,in no way 决不，by no means 决不， 等。
Never in my life have I seen such a stone .
Not a single mistake did he make this time .
Nowhere has the world ever seen such a bird as here .
By no means should we do like that .
Not only was everything he had taken away from him , but also his German citizen .
Nowhere is there a place for him to settle down .
Nowhere can you enjoy such beautiful music .
Ltttle did he know what trouble he was going to have .
Not until quite recently did I hear from her .
Very little did they sleep last night .
对比：Her watch is nowhere to be found . = Nowhere is her watch to be found .
注意对比由 not only … but also 连接两个并列成分作主语时，句子不倒装。
Not only girls but also boys wear such red skirts as that .

1. Thousands of stone blocks were moved and new roof sections were replaced where necessary . 移动了成千上万的石块，必要的地方还换上了新的屋顶。

本句是省略句。常见的省略有：
一、主语中的省略
1. 主句中的省略多见于句首，且多用于非正式文体。如：
(It is) Too bad you can\'t go camping with us next week .
(Is there) Anything more you want to say ?
2. 回答时，主句有时全省去。如：
— When shall we start ? — (You may start) Whenever you like .
— Why is he angry with her ? — (He\'s angry with her) Because she lost his keys to the office .
二、从句中的省略。
1. 宾语从句。
以 which , when , where , how , why 等引出的宾语从句中谓语与主句相同时，可省略谓语乃至主语而只保留引导词。如：
Please hand me any one of these books ; I don\'t care which (you hand me) .
He\'ll return to his hometown , but we don\'t know when (he\'ll return ) .
She can\'t attend this meeting , but we wonder why (she can\'t attend) .
2. 在 I\'m afraid , I believe , I hope , I imagine , I should say , I suppose , I think 等之后的“not”与 “so”分别等于否定与肯定的宾语从句。如：
Will it snow tonight ? — I hope not . (= I hope that it won\'t snow tonight . )
Is he disappointed ? — I\'m afraid so . (= I am afraid that he is disappointed . )
