一道英语题求解

Electrical energy _________ from the sun in a
roundabout way is the most widely.
为什么要用coming 而不能用come

Answer 1

Electrical energy _________ from the sun in a
roundabout way is the most widely.
为什么要用coming 而不能用come

Electrical energy 主语
coming from the sun in a roundabout way是一个现在分词短语，做定语，
is the most widely. 复合谓语
come是动词，不能做主语

Electrical energy coming from the sun in a roundabout way is the most widely. =Electrical energy which comes from the sun in a roundabout way is the most widely.

Answer 2

因为后面已有动词 is ，故用分词coming作状语。

Answer 3

Electrical energy (coming from the sun in a roundabout way) is the most widely.
在这个句子中括号内的句子相当于一个从句，并不是主句，是用来修饰electrical energy的.

Answer 4

分析句子的成分is才是谓语动词 所以你填的词不能是动词原形 要变成动名词 所以填coming

Answer 5

因为后面的 is the most widely 是句子的 be+表语
而coming 是现在分词做定语，修饰 energy
