Today, I learned much knowledge about E-Waste. With the development of technology, there are numerous kinds of garbage appeared, one of them is E-Waste. Nowadays, humankind invented computers and a series of electric products, which is helpful for work and can enrich people’s entertainments. However, many countries and persons don’t know how to deal with the rubbish appearing with electronics, so the pollution happened. People dispose garbage in wrong way like burning or burying, which can’t really solve the problems; these things will pollute the environment.

Many metals like copper, iron, aluminum and gold are wasted, which leads serious environment pollution. However, there are many people are trying their best to save the environment and prevent pollution. They appeal the whole world to pay attention to pollution problems which had a great influence; many countries start to use machine to classify the garbage. Also, there are some famous brands like Nike, they make products with environmental protection materials to show their attitude.

At the same time, more and more people realize that it’s essential to contribute to environment protection, so they start to pay environmental handing fees for it.

I hope the environment will be better in the future with endeavour of the whole world’s people.

Nowadays, technology develops so fast that there are many new fields appeared, and one of them is robotics.Robotics is a emerging technology industry in 21th century. It includes mechanical engineering , electronic engineering, information engineering, computer science and so on. These technology is used to develop robotics, and obviously, robotics has become the most cutting-edge technology now. Robotics can do many things for example, robots can deal with the basic manual labour so that the rate of factory will increase dramatically. Also, robots can replace human to many dangerous assignments like searching the bomb which can effectively decrease the number of police casualties. Most important, with the development of robotics, all the technology about it have great progress, so it is helpful to make our lives more convenient, and now we have various kinds of life robots to provide more and more services to people.In addition, lots of chance of jobs are provided because of robotics. Overall, robotics makes our lives better.

Today, I know the Blog, and I need to use Blog to record what I learned in computer class. The main function of Blog is sharing. On Blog, you can share your own life, and also you can see others’ life activities. If you really like record your life and share with others, Blog is your best choice.

Scratch is a website which provides different operational orders to help people finish what they want. Also, it’s a base of programming because it helps you to build your programming mind. I learned some basic orders these days like asking, saying, moving and so on. I can use them to make a short conversation between two or more persons. It’s not difficult, and I hope I can learn it well.

After a long period time of learning, I finish it, and finally, my classmate and I make a game together. By learning many basic operational orders, I have a deep understanding of Scratch; it’s base on programming, but I don’t need to code because it provides all the things you want. Also, you can’t use it to finish some complex games or projects because of the same reasons, but it’s a friendly software for freshmen who want to learn about programming. At last, I made a game named Gluttonous Snake; it’s a really interesting game. The rules are that firstly, players need to control the snake to eat apples and get scores until game over, when your scores reach a point, it will be a little difficult. To make it, I take plenty of time, I’m so happy although it’s hard. I hope I can do better in programming.

At the end of the term, I need to make a presentation with my group members, and I chose the software because I think I’m more familiar with this topic than others; however, I know I’m wrong. To finish PDF, I found much information on the Internet, by the way, I’m blame on the the features and limitations of various operating systems. After I find information, I have a clear understanding of features and limitations. I know the advantages and disadvantages between different systems. Here is my paragraph. I really hope I can succeed in computer field.

In Grade 10 computer lesson, I learned how to use processing to draw some simple images. Processing is a software which can use Java to code in order to do some design of images. I know many codings for example, if you want to make a variable, I can use int to define a integer and use float to define a bigger range of number. Also, as the time I finished practices the teacher gave me, I became more and more familiar with processing. Here are some of my works.

Now, I finish my study of processing; it brings too many things to me like preparation of Java. Also, because I know C, I can connect two languages and tell the differences and common points, which is really good for me. In conclusion, I learn that how to use code to design pictures or games. I hope I can be better in programming.

Today I have a clear understanding of careers in computers. If I want to keep learning on knowledge on computers, I precisely know what I can do after I gradulate from university in the future. For example, I can be a computer programmer or a software developer if I have firm foundation in coding. They are really nice job for me because I had a dream that being a computer programmer when I was in Grade 6. From this lesson I know that being a computer programmer, for education, I need to have bachelor’s degree and master’s degree. And the salary for programmer is high, it’s said that a excellent programmer may earn 1 millon dollars per year. Also, if a person wants to be good at programming, he or she also needs to have different fields of knowledge, especially in math! It is base that you have goood math mind for becoming a programmer since you need to use mathematical thinking to bulid a model for what you are facing, and then only coding. Also, it’s a good choice to be an engineer, and you have to be versed in physicals to solve many problems inmechanical engineering. For an engineer, it needs to meet the standard in education that finishs bachelor’s degree.
