One possible solution to the problem has recently been suggested by an American scientist, Professor Carl Sagan: he believes that before the Earth's resources are completely used up it will be possible to change the atmosphere (大气圈) of Venus (金星) and so create a new world almost as large as the Earth itself. The difficulty is that Venus is much hotter than the Earth and has only a tiny amount of water.Sagan suggests that algae (藻类), plant life that can live in extremely hot or cold atmospheres and at the same time produceoxygen, should be produced in conditions similar to those on Venus. The algae will be placed in small rockets. Spaceships will then fly to Venus and fire the rockets into the atmosphere. In a fairly short time, the algae will break down the gasses in the atmosphere and change them into oxygen that people can breathe. But before man can set foot on Venus, it will be necessary for the oxygen to produce rain to cool the planet, so that after a few years conditions like those on Earth will be produced.If the experiments are successful, life will become possible there but it will not be pleasant at first. When they go to Venus, the first citizens will have to take plenty of water with them and get used to days and nights lasting 60 Earth days. But there will also be some advantages. They will live longer because their hearts will suffer less stress than on Earth.1.Men may eventually move to Venus because______________________.A. there are many people on the EarthB. we have used too much oil and waterC. the limited resources can't support life on the EarthD. people take up too much space2.Now it is difficult for us to move to Venus because______________________.A. it is too hot for men to land onB. there is no water thereC. we cannot change the environment thereD. it's a long distance for us to go there3.The algae play a very important role in the possible solutionbecause _________________________.A. they can be produced easily on the EarthB. there are a lot of them on VenusC. they can be easily carried to VenusD. they can live in hot and cold conditions and produce oxygen4.The first citizens will find life on Venus not pleasant because___________.A. their hearts will suffer more stressB. their days and nights will last quite longC. there are not any houses thereD. there is too much water there5.One of the advantages the first citizens on Venus will enjoy is___________.A. they will have much more spaceB. they won't suffer from heart diseaseC. their life will last longerD. they will have better living conditions。
