问题 According to the passage, which book is the only book you’ll ever need?
It will be a few years before we can see electronic book for sale because ______.
选项 A、we haven’t mastered the manufacturing technology yet
B、the electronic ink which must be conductive couldn’t be produced in large scale
C、the electronic book will be too expensive to buy
D、you can’t take an electronic book with you anywhere
答案B
解析 本题是道细节分析题。本题所问的电子书还得再过几年才有销售的原因在文章第五段中就已提及：Some hardies—mostly having to do with large-scale manufacturing—remain，so it will be a few years before you see an electronic book for sale in stores.(有些难题—多数和大规模生产有关—仍然没有得到解决，所以还得再过几年你才能看到电子书在书店出售)。文章第八段将所提及的难题具体化了：such ink was recently demonstrated in the lab but has yet to be produced in volume.(这种油墨近来已在实验室演示过，但还不能大批量生产)。这里所提油墨即为上句所说的能导电的电子油墨，由此可判断出B项为最佳选项。A项和C项所说与文章内容不相符，而D项虽与文章内容相符，但并非是原因，因此舍弃。
