问题     Just like children, deer often cross British roads to get to the other side. But the cost is the deer’s life. At night, 【S1】______cars hit and kill the animals. Now foresters are using natural animal【S2】______to prevent dangerous crossings.
    In England, the British Forestry Commission has【S3】______thousands of glowing red "wolf eyes" along woodland roads. The eyes are actually reflectors (反射镜),【S4】______bars like the red reflectors on your bike. The ten-centimeter long bars are fixed on top of posts, with only these signs directed towards the woods rather than the roads.
    When cars speed by, light rays from car headlights reflect off the reflectors shining surface and【S5】______into the woods. Deer are instinctly【S6】______by the wolf eyes — even though wolves haven’t【S7】______deer in Britain or even lived there for a hundred years!
    Scientists think the glowing light【S8】______the "eye shine" of nightly beasts. (You’ve probably seen eye shine on cats. Mirror-like cells in the eyes【S9】______some light that hits them.) The deer must not have "forgotten" that a wolf can run up to【C6】______km per hour in【S10】______pursuit, or can sniff (嗅) deer out from 2 to 4km away.
[A] scared [F] display [K] imitates
[B] installed [G] fancy f L] harmony
[C] plastic [H] harrying [M] hot
[D] instincts [I] flash [N] reflect
[E] speeding [J] hunted [O] instrument
【S2】
选项
答案D
解析 下文主要讲述利用被称为“狼眼”的反射装置保护鹿，由此可知，林人员正利用动物的本能来阻止危险的横穿马路行为，故答案为[D]instincts“本能”。下文提到的Deer are instinctly…by the wolf eyes对本题有提示作用。
