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
【S4】
选项
答案C
解析 分析句子结构可知，50 bars是reflectors的同位语，故本空应填一形容词修饰bars。由常识可知，自行车后的反射镜外缘通常是用塑料制成的，并不昂贵，故答案为[C]plastic“塑料的”。
