概要写作（满分25分）
The journey to the moon has been the first step toward future exploration(探险) in space. The distance between the moon and the earth is very short indeed when compared with the distances between the earth and the other planets. Mars, one of the nearest planets to the earth, is millions of miles away. Travelling to the planets will be man’s next aim. Such travels will be more challenging than the trip to the moon and certainly more adventurous.
Recently, two American spaceships, Vikings 1 and 2 landed on Mars trying to discover whether there is any life on the planet. So far the signs of life on Mars has neither confirmed nor ruled out.(排除)
Russians have discovered that the surface of Venus（金星）is so hot that it is almost certain that there is no life there. Also the atmosphere of Venus is extremely dense and the pressure is nearly a hundred times greater than that of the earth’s atmosphere.
Scientists believe man may find planets which have the same conditions as those we have on the earth, but man should realize the earth will be his only home for a long time and begin to love and care about it.
