一直以来,我就很喜欢上科技课,科技课不仅课堂气氛活跃、生动有趣,而且老师在介绍一些科学知识的同时,还介绍了许多创造发明的小窍门,并鼓励我们去创新,去发明,去实践。因此,我早就有了发明创造的欲望,一有时间,我就要想想生活中遇到的一些事情,总想用新的办法去解决。初三上化学实验课时,我们接触到了测试液体酸碱性的PH试纸,我特别喜欢它,因为就是这么一片小小的纸片,只要你在上面滴几滴待测的液体,从它的颜色就可判断该液体的酸碱性,真神奇!随后我想,要是能把这科学的东西巧妙地运用到生活中,那一定会有意想不到的效果。运用到什么地方呢？我探索了一阵子,没能找到合适的地方,只好暂且把它搁置起来。进了高中,我们专设的科技课虽然没有了,但我还是积极参加了学校发明小组的活动,那PH试纸的妙处,还时常在我脑海中浮现。一天晚上,我看中央电视台的新闻联播节目时,看到了这样一则报道,大概是说有几位外出旅游的女士,由于使用了旅游地区带碱性的生活用水,使皮肤受到了不同程度的损害,她们一气之下告上法庭,找旅游公司索赔。这给了我很大的启示。我想,如今人们都非常讲究生活质量,旅行时,带上一种可以测试当地生活用水酸碱性的PH试纸盒,问题不就解决了吗？
For a long time, I have been very fond of science and technology classes. The science and technology class has not only a lively and lively atmosphere in the classroom, but teachers have introduced some scientific knowledge and also introduced many tips for creating inventions, and encouraged us to innovate and invent. Go to practice. Therefore, I have long had the desire to invent and create. Once I have time, I must think about some of the things I encounter in my life. I always want to use new methods to solve it. During the chemistry class in the third grade, we came into contact with a pH test paper to test the pH of the liquid. I particularly like it because it is such a small piece of paper, as long as you drop a few drops of the liquid to be measured, from its color. It is magical to judge the acidity and alkalinity of the liquid! Then I thought that if this scientific thing can be skillfully applied to life, it would have an unexpected effect. Where to apply? I explored for a while and failed to find a suitable place. I had to shelve it for the time being. In high school, although we didn’t have a dedicated science and technology class, I actively participated in the activities of the school’s inventor group. The beauty of PH test papers often appeared in my mind. One evening, when I watched the CCTV’s news broadcast program, I saw a report that probably said that several women who traveled abroad had suffered from different levels of skin due to the use of alkaline water for tourism in the tourist areas. As a result of the damage, they went to court in an accident and sought compensation from a travel company. This gave me great inspiration. I think that people are now very particular about the quality of life. When traveling, they can bring a PH test carton that can test the water and acidity of the local water. Isn’t the problem resolved?
