18、 W5 P3students need a way to access them. Not everyone has a computer or electronic reader. Schools could print out copies, but that would not help the S3environment.

22、 high schools”可知 D项与此相符。A 项错在 all the books，此组织提供数学和科学材料；B 项与第四段倒数第二句话内容不符。Khosla Family只是提供钱，故 C项错误。4According to Susan Martimo, digital textbooks will _.A. come into fashion from now onB. soon replace traditional booksC. first be adopted by wellequipped schoolsD. surely be approved by school distr
23、icts答案：C 细节理解题。倒数第二段提到她的观点，她认为条件好的学校会首先使用电子课本，但只是作为传统课本的辅助。C 项正确。5It can be inferred from the last paragraph that _.A. schools are reluctant to print out copiesB. the program is not easy to carry out6C. students have no access to the computersD. teachers fail to use the textbooks effectively答案：B 推理判
