Instructions ›
You will hear a recording. Type the missing words in each blank.
* Fill in the missing words into the blank fields
Every  year,  about  10  million  tons  of  paper  winds  up  in  American  landfills  and  incinerators,  which  is  not  only  wasteful  but  adds  CO2  to  the  .  Recycling  helps,  but  even  that  material  has  to  be  repulped  and  paperized  before  you  can  use  it  to  print  out  that  recipe  you'll  never  make.  But  what  if  you  could  wipe  the  page  clean  and  use  it  again?  Light  amplification  by  simulated  emission  of  radiation  to  the  rescue.  A  new  study  shows  that  laser  light  can    the  toner  from  a  piece  of  printed  paper.  The  approach  appears  in  the  Proceedings  of  the  Royal  Society  A.  Taking  a  page  from  the  art  restoration  handbook  scientists  sampled  a  variety  of  light  sources  to  see  if  any  could  be  used  to  strip  the  ink  from  laser    documents  without  damaging  or  discoloring  the  paper.  UV  and  infrared  were  too  harsh.  But  a  bright  green  laser  applied  in  4  nanosecond  pulses  vaporize  the  print,  leaving  paper  that  looks  as  good  as  new.  Such  imprinters  will  probably  run  about  30,000  bucks,  so  they  probably  will  not  catch  on  for  home  use.

Correct answer: atmosphere

Explanation: Here you hear "adds CO2 to the atmosphere". It comes after "to the", so you need a word for the layer of air where gas goes.

Meaning: "atmosphere" means the layer of air around Earth.

Wrong options:

  • atmospere: It leaves out the "h". The right spelling is "atmosphere". Every letter must be correct to get the mark.
Correct answer: erase

Explanation: The speaker says "laser light can erase the toner". You need an action word that means wipe or remove marks.

Meaning: "erase" means to remove writing or marks from a surface.

Wrong options:

  • eraze: It has "z" where the word has "s". The right spelling is "erase". Every letter must be correct to get the mark.
Correct answer: printed

Explanation: You hear "ink from laser printed documents". It comes after "laser", so you need a describing word that ends in ed.

Meaning: "printed" means put on paper by a printing process.

Wrong options:

  • printet: It has "t" where the word has "d". Write "printed". Only the exact spelling gets the mark.
  • printing: "printing" is a close word, but it ends in "ing". The speaker says "printed", which ends in "ed".
