Since America said that on July 20, 1969 the astronauts Armstrong first successful landed on the moon, many people questioned this event was false. Skeptics through the studies on this event, and from many aspects proved their statement was right.

For the first aspect, skeptics were suspicious of the photoes which were taken from astronauts. They found a doubtful point that the photoes were too perfect. They didn't know how could the astronauts take these perfect photoes even though the cameras had no viewfinders and meters. In addition, the pictures didn't show any traces of a blast crater underneath the lunar lander. This was against scientific principle. Because when the lander landed on the lunar surface, its rocket booster would produce 8000 kilograms of thrust so that it could slow the lander. However it certainly would leave a small crater. So, although NASA said these photoes were real, but more and more people are doubtful of them.

For the second aspect, we didn't know how the astronauts could survive from Van Allen radiation belts. These areas would produce very high protons and electrons so that it's difficult for the astronauts to survive except there might have some advanced scientific technology. But, as we know, it's impossible until now. NASA couldn't explain this reason and gave the credible evidence for people.

It really is true or false, hot debate is still uninterrupted. I don't know the process of the event, but I obey the scientific principles. Anyhow, I believe human lands on the moon will not a dream.
 

Hi, Lily. You were able to use some of the transitional devices well. However, do not overuse the conjunction 'and'. Think of other conjunctions so that you could express your ideas more vividly. Furthermore, the concluding part of your essay presented two contradicting ideas. In writing, you have to justify what you have written so that you won't loose your credibility as a writer. Keep up the good work Lily!
