英语作文 online communication 100词左右

The Internet has created a means for people to come closer together. Rather than spending money on phone services, people in different states or even different countries can hop on messenger services, social networking or email to communicate. The Internet allows people to find old friends, classmates, and family members, or meet new people.With the growing popularity of the Internet more and more people are communicating via email. This fast and efficient method of communication is perhaps the preferred method of online communication at the present with thousands upon thousands of emails being sent each day. The many uses of email are what make it so appealing and so versatile. Whether you are sending a greeting to a grandparent or sending files to a coworker, you can easily utilize email to do so. Email has come quite a long way since its introduction, yet it is still used for many of the same reasons. Basic electronic communication has essentially evolved into a more resourceful tool as one has the ability to do much more now then they once could. Along with the usual sending of files and text messages through email, one can send greeting cards, manage their emails by assigning them to folders or classifying them as junk and even organize and manage their daily tasks on some email servers. This wonderful tool is not without its downside however. Some people choose to send worms and viruses via email and in the process infect and damage quite a lot of computers. A virus email can often be very difficult to detect, especially to someone with very little knowledge of computer viruses and how they work. If you notice that you have an anonymous email or an email with a name foreign to you then you may not want to open this email as may likely be a viruses and the mere act of opening the email makes your computer susceptible to infection. Along with the abovementioned problems privacy has also become an issue with email activity. Virtually every email that you send has to go through a number of computers before it reaches the inbox of the intended receiver and along the way there exists a distinct possibility that an individual could hack into your email and read it. Thus it is imperative that you have a bullet proof password. Online communication does not allow users to see one another or speak face-to-face. Though the use of video chat can allow users to speak face-to-face virtually, chat programs and email do not always allow it. An online friendship does not have the same contact as a physical one, such as meeting up in person, contacting over the telephone, and having a conversation, nor does it allow you the physical experience and comfort of having a friend by your side.

However, comparing to the high school, college life is really quite different, and it doesnt like what I imagined. College students are still facing many challenges and problems. The major differences between the two education stages are as follows,
a. In high school, students has to study hard under the pressure from the school and family, because the reality is so strict that for the future college entrance exams they either to be washed out or luckly to be enrolled. College students are alwaws no need to worry about this and they can feel free for their classes.
b. College life is more colorful which in high school often cannt be seen. College students have more options for their life, except study, they can have a party at weekend, plan a travel during hollidays, go for sports as they like and develop their partime interstings, etc.

关于我最喜欢的城市的英语作文150字

我最喜欢的城市(my favourite city) Shanghai is my favorite city. I like it because I was born in there, and a lot of my family members and my friends live there. The shopping in Shanghai is cheaper than here, but it’s expensive in China. I have a lot of things to do there, like: shopping, playing, going to my friend’s home… And there’re also a lot of places that are interesting. In Shanghai, people speak the same language as I do. I was there for 13 years! I left there on August, 18th, 2005. And I was there because I was born in there and I lived there. There’re a lot of people in Shanghai. The people are like me. We all speak the same language. The people in Shanghai are busy and friendly. And Shanghai is also and international city. It’s beautiful and fancy. There’re a lot of tall buildings. That’s why Shanghai is my favorite city. It’s my home city. I love Shanghai!!! I’d like to go back to Shanghai, but just for a visit. Although Shanghai is good, I’d like to live here because I’d like to study here. I only get a little homework and the air here is flasher than Shanghai. The weather is hot in Shanghai. And the best time of year to go there is spring, because in spring, the weather is cool and warm. But some people asked me:” Why don’t we go there in the fall? The fall is also cool and warm.” I don’t think so, because in Shanghai, the fall is still very hot. I’d like to recommend this place to other because I want more and more people to know and visit my hometown. I hope if I ask my friends:” Have you ever been to Shanghai? Do you like Shanghai?” The answers shouldn’t be:” No, I haven’t been to Shanghai. And I don’t even know anything about Shanghai!” Now, I’ll recommend you to go to visit Shanghai in summer vacation or winter vacation or spring break or every time you’d like, you’d want, because Shanghai is a very nice city. If you go there, you’ll soon like it!
