me novels by such great writers as L. Tolstoy, M. Mitchell and C. Bronte.Now, each of them has been whittled down to about 400 pages by cutting 30 to 40 pages percent of original, with words, sentences, paragraphs and, in a few cases, chapters removed.The first six shortened editions, all priced at ￡6.99 and advertised as great reads "in half the time", will go on sale next month, with plans for 50 to 100 more to follow.The publishing house believes that modern readers will welcome the shorter versions.
Group.Thanks for your attention, Mr.Handsome. I must say, the idea developed from a game of "shame" in my office.Each of us was required to confess (承认) to the most embarrassing blanks in his or her reading.I admitted that I had never read Anna Karenina and tried but failed to get through Gone with the Wind several times.One of my colleagues acknowledged skipping (跳读) Jane Eyre.We realized that life is too short to read all the books you want to and we never were going to read these ones. As a leading publishing house, we are trying to make classics convenient for readers but it's not as if we're withdrawing the original versions.They are still there if you want to read them.
