Moles are small animals，about 10-12cm long，with soft grey fur．They spend almost all their time （73）below ground，where they feed on worms and insects．A mole has very （74）powerful front"hands"and claws，which it uses to digthrough the soil and make tunnels（地洞）．It pushes （75）earth up from the tunnels to the surface （地表面），where it makesmounds （土墩）of soil called mole-hills．Gardeners sometimes watch amole-hill．They look to see （76）if there is a slight movement which proves（证明）that a mole is at work below the surface．
Moles are almost （77）blind，but have a very strong sense of smell．They eat nearly all the time and cannot live for more than a few hours without （78）food．Mole tunnels help gardeners and farmers by improving the drainage．（79）However，gardeners hate to see their lawns spoilt（破坏） by mole-hills，（80）As a result，they try to kill moles or make them go away．
