[听力原文] 王师傅：这个星期特累，星期六按理说应该在家好好休息，可是有几个朋友邀我去郊外野游，我不好意思推迟，只好答应了他们。我开车拉着他们，一大早就兴致勃勃地出发了。 杜师傅：我真羡慕你们，你们的运气不错。那天天气不冷不热，又没有风。 王师傅：那天，天公倒是作美。可是车开出去不到五公里，就在半路上抛锚了。我们费了九牛二虎的劲也没把车修好，只好把车推到了加油站请人修，在加油站等了一上午，计划全泡汤了。 杜师傅：那就赶快回来吧，别再耽误时间了。 王师傅：是呀。我一上车就踩足了油门，快马加鞭往回赶。没走几步，半路上突然杀出了一个程咬金，把车拦住了。 杜师傅：怎么了，出车祸了？ 王师傅：不是，是超速，警察要罚款。你说倒霉不倒霉！ 杜师傅：真是祸不单行啊！ 这个星期六他们去哪儿了？（）

第二部分阅读理解

Can you imagine a classroom which misses 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 use up ink at the critical(关键的) moment.

Such a “paperless classroom” is one that more and more schools are trying to get.　　

Students never do any handwriting in the class. Instead, they use 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 Internet. They can look up information on any subject they’re studying, from maths to social science.　　

A middle school teacher Judy Harrell in Florida, US, described how her class used the Web to learn about the war in Iraq in 2003.　　

“We could touch every side of the country through different sites: from the forest to refuges(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 computers,” 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.
