1When I came home father was watching TV 2 I was at a reception at the dentist when the phone rang. 3 While mom was cooking dinner I dress up 4 what were you doing last night from 7 to 9 pm? I'm ready for the exam. 5 When I lived in London I learned English. 6when my friend walked through the city he lost his phone. 7 What were you doing up so late in the office? I prepared the report. 8 When we arrived, they were playing football. 9i looked out the window and enjoyed the scene. The kids played in the yard the elderly sitting on benches some reading some talking.
The poisoning of the world's land, air, and water is the fastest-spreading disease of civilisation. it probably produces fewer headlines than wars, earthquakes and floods, but it is potentially one of history's greatest dangers to human life on earth. if present trends continue for the next several decades, our planet will become uninhabitable.overpopulation, pollution and energy consumption have created such planet-wide problems as massive deforestation, ozone depletion, acid rains and the global warming that is believed to be coused by the greenhouse effect.the seas are in danger. they are filled with poison: industrial and nuclear waste, chemical fertilisers and pesticides. the mediterranean is already nearly dead; the north sea is following. the aral sea is on the brink of extinction. if nothing is done about it, one day nothing will be able to live in the seas.
