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
本句意为:视力好需要有合适的照明,尽管人类的夜视偶尔会被极端的(过明或过暗)灯光的闪现削弱。所填之词在句中作表语,又由a限定,应填名词;因此排除选项A,因是形容词,表示:必要的,需要的;其余三个选项均为名词:B.necessity必要性,需要,必需品(指为了生存所必需的);C.exigency苛求,紧急(事件);D.need需要,必需,必需品(指需要某事或某物,尤其是它们还没发生或还无法利用);因此B为答案。
