The slogan for the day is, “If we drive for one less day, we can have one more nice day.” So far, more than 200,000 drivers have shown their support.

For the first time Venusian scientists managed to launch a satellite in orbit around the planet Earth, and it has been sending back signals as well as photographs ever since. The satellite was directed over an area known as Manhattan-named after the great Venusian astronomer Professor Manhattan, who first discovered it with his telescope 20,000 light years ago. Because of excellent weather conditions and strong signals, Venusian scientists were able to get valuable information as to the possibility of landing a manned flying saucer on Earth. A press conference was held at the Venus Institute of Technology.,_,_,_,_,_,_,_,_,_,We have come to the conclusion, based on the satellite findings, Professor Zog said. There is no life on Earth. How do you know this? the science reporter for the Venus Evening Star asked. 5. For one thing, Earths surface is composed of solid concrete and nothing can grow there. For another, the atmosphere is filled with carbon monoxide and other deadly gases and nobody could possibly breathe this air and survive. 6. What does this mean as far as our flying saucer program is concerned?“ 7. We shall have to take our own oxygen with us, which means a much heavier flying saucer than we have planned.“,_,_,Passage A,_,_,_,_,_,_,Are there any other difficulties that you have discovered in your studies? Take a look at this photo. You see this dark black cloud over the surface of Earth? We dont know what it is made of, but it could give us a lot of trouble; and we shall have to make further tests before we send a Venusian there. Over here you will notice what seems to be a river, but the satellite findings indicate it is polluted and the water is unfit to drink. This means we shall have to carry our own water, which will add even greater weight to the saucer.,_,_,Passage A,_,_,_,_,_,_,Passage A,Sir, what are all those tiny black spots on the photographs? Were not certain. They seem to be metal particles that move along certain paths. They give off gases, make noise, and keep crashing into each other. There are so many of these paths and so many metal particles that they are quite likely to get smashed when we land a flying saucer. What are those pointed objects sticking up?” They are tall buildings that give off light at night. Professor Glom has named them skyscrapers since they seem to be scraping the skies.,_,_,_,_,_,Passage A,you say is true, wont this set back the flying saucer program several years? Yes, but we shall proceed as soon as the Grubstake gives us the added funds.” If all Professor Zog, why are we spending billions and billions of Venusian dollars to land a flying saucer on Earth when there is no life there?” Because if we Venusians can learn to breathe in the Earths atmosphere, then we can surely live anywhere in the universe.,_,_,Organization of the text,Part I (Para. _),Part II (Para. _),1-2,3-14,The satellite landed on Earth has been sending back signals and photographs.,Venusian scientists have come to the conclusion that the Earth is unfit for them to live.,Passage A Is there life on earth,Part III (Para. _),14-18,The Venusian scientists are determined to proceed with the exploration of the planet Earth.,Structure, it has been sending back signals as well as photographs ever since.,(Line 3, Para. 1),之后，卫星便不断地发回信号和照片。,自从三年前以来我一直在学英语。（动作还将继续下去）,has been doing 是现在完成进行时，其构成为：主语+助动词（have/has）+been+动词的现在分词+其他成分。表示动作从某一时间开始，一直持续到现在，或者刚刚终止，或者可能仍然要继续下去。（与since，for连用时，常常表示动作会进行下去）,I have been learning English since three years ago.,Passage A Is there life on earth,The satellite was directed over an area known as Manhattannamed after the great Venusian astronomer Professor Manhattan, who first discovered it with his telescope 20,000 light years ago.,卫星对准的是一片叫曼哈顿的地区, 这个地区是以金星上伟大的天文学家曼哈顿教授的名字来命名的。两万光年前，曼哈顿教授用望远镜首次发现了这个地区。,direct sth. at / toward sth.:,机器将X光射线对准了病人的身体。,The machine directs an X-ray beam at the patients body.,把某物对准某物,(Line 1, Para. 2),Passage A Is there life on earth,name sb./sth. after sb./sth.:,他被冠以他爷爷的名字起了名。,He was named after his grandfather.,以某人/某物的名字给某人/某物命名,Passage A Is there life on earth,who first discovered it 20,000 light years ago 是非限制性定语从句，修饰前面的Professor Manhattan。,The satellite was directed over an area known as Manhattannamed after the great Venusian astronomer Professor Manhattan, who first discovered it with his telescope 20,000 light years ago.,(Line 1, Para. 2),Venusian scientists were able to get valuable information as to the possibility of landing a manned flying saucer on Earth.,(Line 6, Para. 2),金星科学家们得以获得了有关载人飞碟能否在地球上着陆的宝贵资料。,关于哪些学生获得奖学金的决定应当尽快做出。,Decisions as to which students receive scholarship should be made quickly.,concerning:关于,对于这个短语是从哪来的，有两种说法。,There are two thoughts as to where this saying came from.,Passage A Is there life on earth,as to:,年轻人拥有一套大房子的可能性通常是极其渺茫的。,The possibility of owning a large house for young people is usually rare.,做某事情的可能性,Passage A Is there life on earth,the possibility of doing sth.:,man: v. to work at, use, or operate a system, piece of equipment, etc. 在（某系统、设备等上）工作；使用，操纵（某系统、设备等）。manned 在这里是过去分词作定语，修饰flying saucer。,Venusian scientists were able to get valuable information as to the possibility of landing a manned flying saucer on Earth.,(Line 6, Para. 2),“We have come to the conclusion, based on the satellite findings,” Professor Zog said. “There is no life on Earth.”,(Line 1, Para. 3),“根据卫星上的发现，我们已经得出结论，”佐格教授说，“地球上没有生命。”,be based on / upon sth:,我们的关系应当以尊重和信任为基础。,Our relationship should be based on respect and trust.,以某物为基础。,Passage A Is there life on earth,For one thing, Earths surface is composed of solid concrete and nothing can grow there.,(Line 1, Para. 5),首先，地球表面由坚固的混凝土构成，什么东西也无法在那里生长。,for one thing for another:,我不想买这栋房子。一方面太小，另一方面价格太高。,I dont want to buy this house.
