通信专业英语作业(大三第 2 学期)
段落翻译
0801.In contrast to the typical 2 to 3percent response rate in a more traditional classroom
setting, all of the students participating in our project respond to the instructor’s questions.
This suggests that students are more comfortable responding to a question when they see
others doing the same. Another advantage of SWATT is that instructors can see immediately
how well students comprehend a specific topic they have presented.
0802.Using handheld PCs equipped with the appropriate software and connected by a
wireless network to the Internet exposes students to a rich variety of Web resources that can
help them learn abstract chemistry, mathematics, and computer science concepts. This
approach also enhances the learning experience by increasing student-instructor and student-
student interactions.
0803.Teacher training places a heavy emphasis on integrating technology with instruction
and learning, yet the reality of inadequate school facilities often dismays instructors. Mobile
computing technology provides the functionality of a desktop PC to teachers who are
displaced from their room, can’t incorporate technology into presentations, or don’t have a
computer at home.
0804.Popular technologies such as palmtops and Internet-ready cell phones lack a full-scale
browser that can handle a wide variety of Web content. In contrast, in addition to playing
audio and video files, H/PCs already have browsers that support HTML, Java, and JavaScript.
en the increasing importance of the Web to both educators and developers of educational
materials, this difference has profound implications for teaching and learning.
0901.The Internet has forever changed the way we do business. By enabling instantaneous
communication and interaction among individuals and organizations and by providing real-
time global access to information, products, and services, it has also forever changed our
traditional notions of time, distance, information, and relationships. The profound implications
of this change will become even more apparent as we globalize the electronic marketplace.
0902.Finally, we never fully met the challenge of providing reliable and consistent security
infrastructure to support both B2B and business-to-consumer (B2C) e-commerce. We also
need to develop and enforce an effective company security policy to prevent breaches and
make the system less vulnerable or exposed. Although security did not have the same exposure
as other aspects of e-commerce, it is a growing concern.
0903.We have found that mentoring and collaboration in the form of public-private
partnerships are keys to overcoming the knowledge barrier as well as barriers to technology
and to human and financial resources. No organization can answer critical questions-how do
we choose the “right” e-commerce model, how do we measure e-commerce’s return on
investment, and how do we prioritize e-commerce initiatives-in a vacuum.
0904.A key factor to successful collaboration, of curse, is the willingness to share what you
know. But more than ever, I believe companies are realizing the advantages of alliances and
openness. Only together can we beat the toughest problems and continue the evolution to an
electronic economy.
