The camel was very thirsty. His last drink had been weeks ago. His feet sank in the hot sand and he ___COULD___ hardly move. "When will I reach water?" he thought. "And I __HAVE NOT EATEN_ for ages." It was obvious that if the camel didn’t find any water and food soon, he _WOULD DIE__. He made a few steps toward another dune. It was __EASIER_ to walk along the top of a hill, than along the bottom. At last he __SAW__ something green in the distance. Was it a mirage or an oasis? He hoped for the best and the hope helped _HIM_ move faster. Soon, that distant green colour turned into real trees and grass. There _WAS__ a small stream of water and some palm trees that gave shade. Their wide __LEAVES__ could protect the camel from the sun's rays. Though the sun __WAS SHINING_, it didn’t burn anymore. Unfortunately, it was impossible to stay there forever. A short rest and the camel had to move on towards his destination.
'Surfers Against Sewage' (SAS) was founded in 1990 by water sports enthusiasts in the UK. They are an environmental _ORGANIZATION_ that tries to protect the UK’s oceans and beaches. They say that it may be really _RISKY_ to swim in the seas, and even sunbathe on the beaches because of the pollution. When SAS appeared, it informed people about the problem in quite an _UNUSUAL__ way. They went to public events with their surfboards and handed out leaflets. They _QUICKLY_ attracted the attention of the media and people of Britain. They even managed to put pressure on the _GOVERNMENT_ to forbid dumping waste in the sea, rivers and lakes. The campaign was indeed _SUCCESSFUL_. Officials agreed to spend 8.5 billion pounds on cleaning up Britain’s seas and rivers.
