B. achieving a constant flow of power from an unpredictable natural source, which meets demand but without overloading
C. how to achieve a constant flow of power from an unpredictable natural source, a flow that meets demand but does not overload
D. how to achieve a constant flow of power from an unpredictable natural source, but a flow that meets demand without overloading

待大牛前輩鼎力相助解答

不是大牛，有誤請指正。

A that修飾natural source，錯。因為natural source無法控制而去meets 需求。so 連接詞，與BUT重複功能，但也可翻成「如此的」（adj）所以應該不作連接詞也可，但很這樣槁幹什麼ㄌㄟ，超累贅。

B 同A，which修飾的對象也是natural source，完全是一個錯。

D 不平衡，通常逗號後的對等連接詞必須符合S+v, but s+v 所以囉！也錯。

E which指代不清，一般是修飾逗號最接近名詞，此選項最接近名詞為natural source，完全就不對。

無路可走，選C，C對了～


快速答題。
讀懂句意，problem需用方法去解決，用how比用is achieving 好，刪AB，D不平衡也刪，E被動不好再刪。
只好選C，C對了。



更快速答題。
看到C選項a flow 表同位，不要猶豫，馬上給它選下去，因為是ETㄟ屎的最愛，估計錯的機率不高。
但如果錯了。

欣然接受。
