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