您好！

One of the big advantages of information technology is that it can provide access to university education for a much wider range of people. Having material available for 24 hours a day, rather than for only two or three hours a week, means that those who work full-time, who work shifts, or who have family responsibilities can learn from it too.
信息技术的一大优势是可以为更广泛的人群提供接受大学教育的机会。提供学习资料的时间是全天候的，而非每周两三个小时。这就意味着，全职工作者、轮班工作者或者家庭主妇/家庭主夫可以从中学习。

Information technology makes it possible to provide better-quality learning in the following ways:
信息技术通过以下几种方式提供更优质的学习机会：

Material online can be richer than that provided through the combination of lectures and libraries. Multimedia systems make it easier to provide high-quality images, audio, and videos.
网络资料比讲座和图书馆提供的更丰富。借助多媒体系统，可以提供高质量的图像、音频和视频。

Material online can be more consistent. The use of multimedia shifts the balance in favor of capturing the best practice in each areas of teaching--the best teacher's lecture, or the best explanation of how to solve a problem can be recorded, and made available to all current and future students, not just those who were physically present at the time.
网络资料一致程度更强。使用多媒体可以平衡以下来源的教学资料：捕捉到的不同区域的优质教学内容和记录下来的问题的最佳解释。并且可以使当前的以及未来的学生受益，而非限制于当时亲临现场受教的学生。

Material can provide alternatives for ways of learning, responding to different student learning styles. For example, some students are comfortable with symbolic thinking. Others prefer to learn by doing--they can experiment within simulations. Others prefer to learn visually, and they can be provided with images and videos.
网络资料可以因材施教，根据学生的喜好提供相应的学习方式。比如，有些学生习惯象征性思维（抽象思维）。其他学生却更倾向于理论与实践相结合——他们可以一边学习，一边做模拟实验。还有一些学生更喜欢直观学习，从网络资料中获得图像和视频。

Online courseware can teach the skills for finding appropriate information in large systems. For example, the World Web already contains more information than the largest libraries in the world.
网络课件可以教学生们搜索信息的能力，从庞大的信息系统中查询到恰当的的信息。比如，“世界网站”包含的信息比世界上最大的图书馆包含的信息都多。

Finally, online courseware creates the opportunity for a new kind of interaction with peers, although it is an intellectual interaction rather than a physical one. Traditional lecture courses allow only fleeting opportunities for interaction between students.

最后，网络课件为同学们提供了一种新的互动方式。虽然这种方式是智力上的精神互动，而非面对面的互动，但是比传统讲座形式中的一闪而过的短暂互动方式更久。

这个文章，应该不难吧？即使有不认识的单词，查查就可以了吧，没有什么复杂的句型

什么？没有文章啊
