Now foresters are using natural animal (2) to prevent dangerous crossings. In England, the British Forestry Commission has (3) thousands of glowing red "wolf eyes" along woodland roads. The eyes are actually reflectors (反射镜), (4) 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 offthe reflectors’ shining surface and (5) into the woods. Deer are instantly (6) by the wolf eyes-even though wolves haven’t (7) deer in Britain or even lived there for a hundred years! Scientists think the glowing light (8) the "eye shine" of nightly beasts. (You’ve probably seen eye shine on cats. Mirror-like cells in the eyes (9) some light that hits them. ) The deer must not have "forgotten" that a wolf can run up to 72 km per hour in (10) pursuit, or can sniff (嗅) deer out from 2.4 km away.
