Step two:Classifying the passage.

　　When you caught this light our for the tough topic, you must to pick up theportion of describtion and thereby to list the reasoning one by one. I quotedthe passage again:

　　"As Earth was being formed out ofthe collision of space rocks, the heat from those collisions and from theincreasing gravitational energy of the planet made the entire planet molten,even the surface. Any water present would have evaporated and gone off intospace. As the planet approached its current size, however, its gravitationbecame strong enough to hold gases and water vapor around it as an atmosphere. Because comets arelargely ice made up of frozen water and gases, a comet striking Earth thenwould have vaporized. The resulting water vapor would have been retained in theatmosphere, eventually falling as rain on the cooled and solidified

　　surface of Earth. Therefore, the water in Earth's oceans must have originatedfrom comets."

　　In my opinion, I tend to makethis pink part as the whole background of the Earth being. Rests of it is thereal reasoning of this author stated his own minds. So you just to be believedto this process and leave the REALISITY alone. Based on this evidence theauthor given to turn your argument out.

　　Setp three: Analyzingthe reasoning.

　　Untill now, whatever youhad be surprising or raptured, the fact is apparent standing in here, which isa simple structure he done. You can see clearly the err and the how caused tothem.

　　Firstly, this is aseries of unfairly causalities. And that is also the major vice the author appeared.I will detail it from three aspects.

　　With the constructionof comets,the author did not provideany evidence to demonstrate the frozen water and gases are the major substancesmade up in it. For the metter, vapor may be the one consequence of allpossibilites of comets cracked to the Earth.

　　Therefore, how the waterhad being generated and droped down the earth is a unconvincing assumption.

　　With the parttern ofraindrop,even though weaccknowledged the foregoing point is alright, the author still were short ofthe evidence and nesassary intruduction of other partterns the water formed inour Earth.

　　And it also could bedoubted because the author didshow us the definite information of this raindrop. What the amounts of thewater came from raining was? Are there other space rocks have such kindssubstances which can produce the water? Lacking these information, the authorcan not point out his final study.
