Nowadays, with the rapid development of information technology, internet and electronic commerce have been very popular in our daily lives. For example, it is fashionable for youngsters to purchase daily essentials, such as books, clothes, electrical equipment, on some famous website, like Taobao, EBay and Alibaba, through many courier companies.
As we all known, online shopping has many advantages. Firstly, online shopping is more convenient than traditional means. We can find a shop with so many goods that we may favor, while all these just need clicking our mouse and typing-in the key word of what we want to find. And it also saves our a great some of time. Secondly, more choices than real store are another attraction to customers. Online shopping can provide mass information about products which can be suit for customer's needs, tastes, and preferences. Thirdly, as without traditional warehouses and retail shops, online shopping has can make us gain lower costs and prices.
However, in spite of its advantages, we can't turn a blind eye to its disadvantages. Obviously, quality problem is its first disadvantage. Customers always buy fake commodities which are not described as online shops. In addition, it's troublesome and annoying for us to make a change when they are not satisfied with what we bought online. The second disadvantage is security issues. When we shop online, we need pay for the commodities by electronic payments, but hackers can invade our computers and steal our information, this is not safe for online shopping.
Maybe we have accustomed to online shopping, just like me who often shop daily essentials by internet, but I expected that more effective measures should be taken to make it better. Specifically speaking, government and bank should work out strict regulations and rules to prevent unfaithful and illegal activities of online shop owners. Only by this way can online shopping become really safe and attract an increasing number of customers.
At the same time, the movie manages to surprise you with an original screenplay and leaves you with a lot to ponder. As many of us have been brainwashed by Hollywood, you can only expect a 'humans vs. aliens' movie to be full of action and scattered plot. But this film awakes us from the introspection of human sin and wrongdoing, if the inhabitants in the slum were not aliens but real people, are we sure the same thing could not happen today? Isn't it a reflection of what the powerful do to the disadvantaged in the world today? As doubts fulling with my heads, I even began to wonder which side I should root for during the screening.
When we were child, heads were full of dreams. Maybe you wanted to be a scientist, doctor, engineer, or teacher. While we grow up, many things have been changed. There are many reasons for that. I think the most important one is our real life. We are busy to make out the problems in life, or we are always attracted by other things which are not relevant to our dreams.
I still remember that becoming an electronics engineer was my dream. I had a strong curiosity to electronics, especially like Electric toy car, radio and robot. I was influenced deeply by some cartoons, like the Japanese anime. But I become an employee in a company who need do things which are not about my major. The dream of my childhood has immersed in heart. It's just a beautiful ideal, which only comes out in my sleep.
Having a dream is not difficult, but how to make it come true is very hard. To realize my dream, I tried my best to learn. When I entered a university, I chose the automation specialty, because it was closer to my dream. When I graduated from the university, I was aware of that I had to find a job to make a living. Dream is not reality, it's just a dream which will always be the bottom of my heart.
Nowadays, artificial intelligence, which is becoming more and more familiar with us with the development of science and technology, is infiltrating into our daily life gradually, and it brings great convenience and progress to our society. Although we don't have a great knowledge about the specific content of artificial intelligence, we enjoy the convenience and benefit that artificial intelligence brings to us. We can say that artificial intelligence is changing the way of our living, learning, working and so on.
Artificial intelligence can be scripted as a new science and technology, which is used to simulate human intelligence. Namely, computers simulate the way of human's thinking and intelligent behavior, such as Learning, Reasoning, Thinking, Planning, and so on. We can't deny the fact that artificial intelligence is of great application nowadays. For example, a lot of intelligent computer or household appliances come into our life, intelligent robots help us to finish some difficult work that we can't do by ourselves, and intelligent control has improved our working greatly. We can say that artificial intelligence exists everywhere.
As one of the three most cutting-edge technologies in twenty-first Century, artificial intelligence has a very bright prospect. However, The biggest obstacle of it is that it is a subject, which is related to computer science. Psychology. Philosophy and other knowledge. Therefore, what we should do is to study hard, widen our knowledge, and consolidate our professional knowledge. Only by this way can we do contribution to the development of artificial intelligence and the improvement of our lives.
