Detection of Earthquakes: A Great Challenge for Human Beings
On May 12th, 2008, a terrible earthquake happened in Sichuan, China. When people are engaged in helping the unlucky compatriots, they all have the same questions in their hearts: “Didn’t we notice any exceptional things happening before the earthquake occurred? Why couldn’t we predict it?” After reading passage 1, I have some ideas about the detection of earthquakes. Actually, an accurate detection of earthquakes has long been a dream to people all over the world and no country has found anything really associated with the occurrence of earthquakes till now because of the insufficient convincing symptoms before an earthquake. There are two aspects to explain this. One is because that the gestation of an earthquake is extremely complicated and we have not fully understood its intrinsical principles yet just at the current technological level. As is known to all, to detect a particular earthquake is to predict the accurate time and location of it, and also we have to estimate its magnitude and the damage it will bring to us. However, all these things still rank high on the list of unmet challenges now. The other reason is that since the slight change caused by an earthquake usually happens in an underground circumstance and it is always of low probability, a reliable signal to show when and where an earthquake will occur is still unavailable because the existing predictions are mostly based on people’s living experiences, which are born with unavoidable limits. Even though we have noticed something strange happening before an earthquake, we cannot tell that an earthquake is about to come because some human behaviors, the change of environment and climate may also result in uncommon things. Although we are not able to make perfect detection of earthquakes at this moment, fortunately, with the development of science and technology, we are gradually getting to know more about such natural disasters and trying to find ways to avoid them or decrease their damages. I believe that it will not take long before we solve this global problem completely. Modern technology will surely overcome this challenge!

Content- Clear content showing your idea that detecting earthquake is a challenge in the engineering technology.
Good uses of linking words like However, Although.
However, when you says there are two aspects that making detecting of Earthquake diffcult due to insufficient convincing symptoms, you only touch on one aspect although you stated that there are two aspects to this. I suggest that if you only want to touch on one, you should briefly mention the other one but tell the reader you will only be focusing on one.
Orgainsation- Good paragraph structure. Idea (challenge of detecting earthquake), then explaination (due to the two aspects), finally the concluding part.
However, no clear concluding sentence and your topic sentence, "Actually, an accurate..." seems to focus on the reason for your idea instead of the topic that detecting earthquake is a challenge for engineers. I suggest that you should put in such a sentence at the start of the paragraph so the reader knows what's your focus
Nice work for your first piece
Cheer!
Great use of vocabulary in the article like gestation. the flow of the article is smooth and easily understandable.however, there are some run-on errors and an over usage of connectors like 'because'.
