Practice Listening: Fill in the Blanks (Type In) ID: #33252 Short Dam
Instructions
* Fill in the missing words into the blank fields
Dams  are  huge  man-made  structures  that  act  as    on  a  river.  Today,  the  main  reason  people  build  dams  is  to  produce  electricity.  They  are  also  built  to    and  control  the  flow  of  water  in  a  river.  Throughout  history,  dams  have  been  used  to  prevent  flooding  and  to    farmland.  Dams  supply  about  a  sixth  of  the  world's  electricity  and  they  significantly  reduce  the  risk  of  floods  and  .  They  also  make  water  easier  to  access,  especially  in  desert  like  areas,  where  water  is  in  low  supply.  There  are  however,  some  negative  effects  of  damming  rivers.  Many  people's  homes  are  knocked  down  to  make  space  for  the  dam,  and  flooding  can    in  the  reservoir,  which  is  the  area  behind  the  dam  where  water  collects  .  This  can  cause  valuable  farmland  to  become  submerged  under  the  lakes.
