第一节（共15小题；每小题2分，满分30分）
阅读下列四篇短文，从每小题后所给的A、B、C、D四个选项中，选出最佳选项。并在答题卡上将该选项涂黑。
Imagine a classroom missing the one thing that’s long been considered a necessary part to reading and writing ------ paper. No notebooks, no textbooks, no test paper. Nor are there any pencils or pens, which always seem to run out of ink at the critical moment.
A “paperless classroom” is what more and more schools are trying to achieve.
Students don’t do any handwriting in this class. Instead, they use palm size, or specially-designed computers. The teacher downloads texts from Internet libraries and sends them to every student’s personal computer.
Having computers also means that students can use the Web. They can look up information on any subject they’re studying from math to social science.
High school teacher Judy Harrel in Florida, US, described how her class used the Web to learn about the war in Afghanistan (阿富汗) before.
“We could touch every side of the country through different sites from the forest to refugee camps (难民营)”, she said. “Using a book that’s three or four years old is impossible.”
And exams can go online too. At a high school in Tennessee, US, students take tests on their own computers. The teacher records the grades on the network for everyone to see and then copies them to his own electronic grade book.
A paperless classroom is a big step towards reducing the waste of paper. High school teacher Stephanie Sorrell in Kentucky, US, said she used to give about 900 pieces of paper each week to each student.
“Think about the money and trees we could save with the computer,” she said.
But, with all this technology, there’s always the risk that the machines will break down. So, in case of a power failure or technical problems, paper textbooks are still widely available for these hi-tech students.
46. What does “run out of ink at the critical moment” in the first paragraph mean?
A. Pens may not write well at the critical moment.
B. Pens get lost easily, so you may not find them at the critical moment.
C. Pens may have little or no ink at the critical moment.
D. Pens use ink, while pencils don’t.
47. The high school teacher, Judy Harrell, used the example of her class to show that ______.
A. the Web could take them everywhere
B. the Web taught them a lot
C. the Web is a good tool for information
D. the Web, better than the textbooks, can give the latest and comprehensive (全面的) information
48. The paperless classrooms will benefit ______ most.
