A. look up B.unfair C. achieve D. important E.libraries

Imagine a classroom missing the one thing that has long been considered a(n) 1 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 when we really need it.

A “paperless classroom” is what more and more schools are trying to 2.

Students don’t do any handwriting in this class. Instead, they use specially-designed, or palm size computers. The teacher downloads texts from Internet 3 and sends them to every student’s personal computer.

Exams can go online too. At a high school in Tennessee, US, students take tests on their own computer. The teacher records the 5 on the network for everyone to see and then copies them to his own electronic notebook.

A paperless classroom is a big step 6 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 7 that the machines will break down. So, to avoid (回避) it, paper textbooks continue to be 8 available for these hi-tech (高科技) students.

【题目】 Today there are more fires than in the past. Over 100,000 wildfires burn each year in America. Russia has 20,000 to 35,000 wildfires every year. Australia has on average 60,000 each year. These fires destroy huge areas of forests and burn hundreds of homes.

Many experts believe _______. The first is climate change. Recent weather has been warmer and drier. This leads to dangerous fire conditions. When lightening strikes, dry grass easily catches fire. Hot winds add to the problem. The wind spreads a fire quickly. In 2010, Russia had the hottest and driest summer in a century. In just one month, 500 fires destroyed over 2,000 homes. Some people lost their lives.

Traditional fire-fighting practices are another reason for the increase in fires. In America, firefighters used to quickly put out every fire. They didn't allow the grass and trees to burn. As a result, today many forests have thicker vegetation(植被). Thicker vegetation means more fuel for fires. also, without fires from time to time, forests become overcrowded and unhealthy. Some trees are dead. The dead wood then easily catches fire. So surprisingly, America has many more fires today partly because of its past fire-fighting practices.

Scientists now understand that a fire can be a natural part of healthy forest. As a result, countries like Australia allow more fires to burn naturally. Sometimes, fire fighters even start fires to get rid of dead wood. Of course, they carefully control the fires. The fire thins out old trees. This allows sunlight to reach the ground. As a result, fires help new trees to grow. Therefore, if a fire is not a serious threat to people, firefighters may let it burn naturally.
