Speak______ ,please,because I can't hear a word from the back

问题描述:

Speak______ ,please,because I can't hear a word from the back
Well ,it's ______________enough.
A.loudly;loudly B.louder;loud
C;loud;louder D.loud;too loud
请写出理由,

B
loud既可以作形容词也可以作副词,本题里第一空在动词后面,应该接副词,第二空在it is后面接形容词,而且后面有enough,只能接形容词原形.
所以这样排除法,只能选B
翻译:请再说大点声,我在后面听不见.
已经很大声了.
