Proper lighting is a
necessary
for good eyesight even though human night vision can be temporarily impaired by extreme flashes of light.
选项
A、needful
B、necessity
C、exigency
D、need
答案
B
解析
本题考查词语应用。句意为:合适的照明是视力好的必要条件,尽管人类的夜视偶尔会被极端灯光的闪现损害。所填之词在句中作表语,又由不定冠词a限定,所以应为可数名词单数。A是形容词,表示“必要的,需要的”,故排除;necessity“必要性,需要”,符合句意;exigency“苛求,紧急(事件)”;need“需要,必需”,为不可数名词。因此,答案是B。
