【題目】閱讀下列短文，從每題所給的四個(gè)選項(xiàng)（A、B、C和D）中，選出最佳選項(xiàng)。
It has been more than twenty years since pioneering British computer programmer, Sir Tim Berners Lee, created the World Wide Web. But could he have ever imagined how much the web would change our lives? And would he approve of how some British students are taking advantage of his invention?
Univesities and exam boards around the UK are becoming increasingly concerned with the rising number of cases of plagiarism, many of which are facilitated（助長(zhǎng)）by the Internet access.
In the UK most school and university students complete coursework throughout the academic year which contributes toward their final mark. In many cases coursework makes up the main part of the qualification. Since coursework is completed in the students’ own time it cannot be monitored by teachers in the same way as an exam.
Derec Stockley, director of examinations in the UK, explains, “Plagiarism affects coursework more than anything else, and in the cases that come to our attention, more and more are linked to the Internet.”
At a university level recent reports suggest that plagiarism has evolved from separate cases of individual cheating t o systematic and even commercial operation. Students can now pay for bespoke essays to be written for them by experts.
It is estimated that the market in online plagiarism is now worth 200 million pounds a year. Every month more and more websites offering to write students’ essays for them appear on the Internet.
Barclay Littlewood, owner of Degree Essays UK employs 3,500 specialist writers and charges between 120 pounds and 4,000 pounds per essay. However, Mr Littlewood refuses the accusation that he is helping students to cheat.
（1）What does the underlined word “plagiarism” in Paragraph 2 mean in the passage?

A.Cheating.

B.There will be no problem if online plagiarism is a systematic and commercial operation.

D.Teachers should lay more emphasis on exams than coursework.
（3）It can be inferred from the text that the author seems to ______.

B.worry about the quality of students’ coursework influenced by the World Wide Web
C.be in favour of Littlewood’s defence against the accusation of him

（4）Who should be blamed for online plagiarism?
A.Barclay Littlewood.
B.Sir Tim Berners Lee.
