HsinChu


Last semester, my classmates and I went to HsinChu to do our project for English class. We visited many places and saw many special things there, especially for the architectures. The city government made much effort to preserve them.
Actually, I had lived in HsinChu for four years. Hence, this is a place that I am familiar with. People call this city as wind city because of its big wind. For example, sometimes the whole row of motorcycles might be blew down by wind. However, people lived in HsinChu use the wind to make a kind of delicious rice flours.
The city is famous for the HsinChu science park. There are many tech companies standing here and output many high-tech products, which earn lots of money from foreign countries and improve our economic development.

The situation of Myopia in Taiwan

The situation of Myopia in Taiwan
Myopia is one kind of eyes impairment, which is very general in Taiwan, especially for students. By the statistics of Department of Health, Executive Yuan, there are approximately 84% of senior high students who have myopia. The factors causing myopia might be categorized into gene and use of eyes improperly.
If our ciliary muscle is over stretched, it might not be recovered to the original situation, which is the reason why myopia is caused. Furthermore, our eyeballs will change the shape to adapt this condition, which makes the eyeballs too long and the exact view can’t be focus on the retina.
Gene is a reason why myopia is caused. There is a gene, PAX6, involving the growth of the eye. According to a British researcher, Dr. Hammond, the gene PAX6 has close relation with the fundamental eye development (Hammond, 2004). Dr. Hammond and his colleagues compare 211 twins at their genetic makeup and found this evidence. Additionally, for example, they put gene PAX6 on the leg of a fruit fly and eye developed onto that leg! However, it is not a mutation. It is a variation. If the gene over express, the eyeball won’t stop growing until the distance of focus is beyond the normal distance.
Using of eyes is another important factor to cause myopia. Especially for most people, this factor might be more dominant. In the modern life, people spent more and more time in multimedia, which makes eyes overloaded. For students, they have to study harder to acquire more knowledge and information. They use their eyes to read , and they may even search information on the web or through other kinds of media. Besides studying, in the leisure time, they use their eyes on TV or computer for online games, websites, or chatting. In conclusion, the eyes rarely take a break and work too much. According to Dr. Liang, over-using eyes on the computer might make eye tiring, dry, sore, filled with blood and high-pressure (Liang, 2007).It is a urging situation to reduce the percentage of students with myopia. Because there are too many students having myopia in Taiwan .Myopia not only make life inconvenient, but also cause other diseases. Therefore, we should change our mind and habits to use our eyes properly. It will lead a good result for our health and better progress for our country.
