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 (关键的) 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 (手掌) 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 maths to social science.

High school teacher Judy Herrell in Florida, US, described how her class used the Web to learn about the war in Afganistan (阿富汗) over one year ago.

"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 computers," she said.

But, with all this technology, there's always the risk (危险) that the machines will break down. So, in case of a power failure or technical problems, paper textbooks are still widely available (可用的) for these hi-tech students.

1. What does the part of the last sentence in the first paragraph, “run out of ink at the critical

moment”, 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.

2. In a paperless classroom, what is a must?

　 A. Pens. B. Computers. C. Information. D. Texts.

3.The high school teacher, Judy Herrell, 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

4.The paperless classrooms will benefit _____ the most.

　 A. students B. teachers C. trees D. computers

5.What does the phrase in the last paragraph, “break down”, mean?

　 A. Break into pieces. B. Stop working. C. Fall down. D. Lose control.

When most people think of giant pandas, the pictures of the cute, black-and-white bears from China that eat bamboo will immediately jump into their mind. Scientists from Mississippi State University, however, are interested in what they leave behind: their poop(排泄物). At a recent meeting in Denver, Professor Brown at the university presented her research showing how panda poop could inspire a new way to obtain energy from plants, which are a renewable energy source. Usually, plants can be called biomass(有机燃料) when they are used as an energy source.
Burning biomass is one way to capture its energy, but Brown hopes panda poop can teach scientists something about breaking down biomass. Pandas—or at least the bacteria in their stomachs—are very good at getting energy out of bamboo. Unlike cows, which use 4 stomachs to digest large amounts of grass, a panda has only one stomach. Bamboo comes in, and poop goes out.
Every day for 14 months, Brown and her team on this project, counted the bacteria in the poop of the two pandas, YaYa and LeLe living at the Memphis Zoo. Her studies turned up 12 species of bacteria that break down biomass, including one that had never been found in pandas. Brown says that because the poop contains bacteria that break down biomass, it could also be used to break down other types of biomass.
Now the scientists hope to identify the chemicals that help with the process of breaking down biomass and then figure out how the bacteria work. If those chemicals can be made in the lab, they could be used to turn biomass—like grass or other plants—into fuel.
Brown says she doesn’t mind handling panda poop. “It’s probably the most pleasant material to work with,” she says, “My colleagues and I have been working with other poop for a long time, and we can assure you it has a fairly pleasant smell associated with it.”
【小题1】The importance of studying panda poop is _______.

COOL INVENTIONS
CHARGE ON THE GO
From school to band practice, the Venturi Eclectic is an Earth-friendly way to get where you want to go. This battery-powered, zero-emission(meaning it doesn’t pollute the air) vehicle runs mainly on renewable energy. Solar panels on the Eclectic’s roof absorb sun rays when you’re driving. On windy days, you can connect a machine to the car’s roof collects energy from the wind while you’re parked. The Eclectic’s top speed is 28 miles an hour; the battery lasts for 31 miles before it needs to be recharged. Zipping （迅速行进）round the neighborhood has never been better.
WATER CLOCK
Here’s an eco-friendly way to tell time: Simply fill the Bedol Water-powered Clock’s tank（箱）with water, add some lemon juice, and the clock will display the time without the need for environmentally harmful batteries. There are two sets of metal electrodes（电极）inside the water tank. Water contains ions（离子）that carry negative and positive charges. These ions complete a charge between the electrodes creating enough energy to power the clock. Just refill the tank every few weeks, and this clock will keep on ticking.
LAND ROCKET
Bloodhound SuperSonic Car (SSC) will be the first car to attempt to break the 1,000-mile-an-hour barrier. (The current record is 763 miles an hour.) a concept for now, the rocket-shaped car gets its initial push to 350 miles an hour from a jet engine. Then a rocket fires up, pushing the SSC past 1,000 miles an hour. In order to keep the car streamlined（流线型的）the driver lies back at a 45-degree angle.
COOL CAMERA
You’re having a blast at your friend’s birthday party. But when it’s time to bring out the cake, everyone crowds around, blocking your view. No worries. Throw the Triops into the air, and this clever camera captures the view from above. The Triops can take three pictures at once, each from different angles. You can also record sounds and command the Triops to start shooting whenever it hears that noise. That’s one smart camera.
