It has been nearly seventy years since the first computer ENIAC was made in Pennsylvania University in 1945. Computers have developed(用has been developing 把) in (at) an incredible pace. At the same time, Internet, as one of the major appliances of computer, has become an indispensable part in our life.
First(ly), Internet makes it easier in getting information all we need(ed). With the help of Internet, there is always no need to buy a newspaper, the only thing that need to do is to open a news website on your monitor simply with the keyboard and mouse. Moreover, the news on the Internet are(is) always later than these on the news paper(newspaper). CNN, for instance, the news on its website is updated by minute or sometimes even by second. However, the news on a newspaper usually is the affairs happened yesterday Using a search engine, such as Google, Yahoo, Live search, and the list will go on, one can easily obtain the message you want.
Second(ly), scientific researches are improved by Internet. In the past, the communication between two institutes, especially for the two located in different countries, are really difficult. In order to deliver some documents, they had to resort to the definitely inefficient and time-consuming snail-mail, many more urgent scientific procedures were delayed. Nowadays, the research institute all over the globe could be attached into a whole, and the share of some accessible resources are become possible. For example, a share of experimental data could attract more people of the same interest to participate in the research project, therefore diverse methods will be applied. All these contribute a lot to today's scientific breakthrough.
例子有些散,但可以看出是从两方面来提高scientfic researches的,一个是速度方面,一个是resourse sharing,中心句可以更明确一些

All too often we observe that the pirate of software, movie and music is never difficult to find on the Internet. Blue and violent(不地道.用indecent unwholesome suggestive amorous..) pages are also easy to find on the Internet. It is really dangerous(inimical) for the children to the exposure too much to these pages. A further more self-discipline is necessary for children. For example, there are countless game websites on the Internet, children have to learn to control over these temptations.UM
