问一下，句首的that到底什么意思？做什么成分？怎么无端端放在句首？

E错在哪里？

第一题中的are beginning to raise alarms.说明COST是水价上升这件事情还没有发生，所以用WILL比较好

正解！at a cost of 是idiom表示X准备好牺牲某物而去做那件事，原句子重心不是再说propose这个动作本身不对，而是说那一串projects设计不合理，成本太高。

后来发现这个解释是很有道理的。

参考这题

Except for a concert performance that the composer himself staged in 1911, Scott Joplin’s ragtime opera “Treemonisha” was not produced until 1972, sixty-one years after its completion.

(A)  Except for a concert performance that the composer himself staged

(B)  Except for a concert performance with the composer himself staging it

(C)  Besides a concert performance being staged by the composer himself

(D)  Excepting a concert performance that the composer himself staged

(E)  With the exception of a concert performance with the staging done by the composer himself

Idiom + Rhetorical construction

This sentence requires attention to idiom and to conciseness. Except for is correctly followed by a noun, concert performance; that the composer staged himself is a clause that dearly and concisely describes the performance.

A     Correct. In this sentence. the correct idiom is used in a clear and concise expression.

B     With…it is an ungrammatical construction; staging suggests ongoing action rather than action completed in 1911.     

C     Being staged suggests ongoing rather than completed action; the passive voice is wordy and awkward.

D     Excepting usually appears in negative constructions; it is not the correct idiom in this sentence.

E     This sentence is awkward and wordy.

The correct answer is A.

第一题已经明白了 1是ing一般表示正在进行 2是整个逻辑结构边成proposed plan的代价，对吧？

AlienX能不能详细点？

之前没有见过这种句型

是不是凡是想把一个从句作为主语，前面都可以放个THAT呢？

谢谢
