【题目】

It was a February afternoon in a Brooklyn classroom. Sixteen-year-old Taylor Engler came face to face with a cow. But it was all in her head. She was transported by a virtual (TE拟的）reality (VIO headset-it took Taylor and her classmates to a farm 250 miles away. For students，the technology means field trips are no longer limited by the length of a bus ride.“I was not expecting it to be right in my face！”That's what Taylor said after taking off the headset and finding herself back in the classroom.

On any school day, students can take virtual reality “trips". They are deep-sea diving. They are observing medical operations. They are visiting the Science Museum in London. Teachers say it's another way to involve the iPhone generation（一代人）into classroom learning and it can help with their understanding and improve their grades. Calm Jones, a science teacher, has walked students through the northern forest with a Google app called Expeditions. “It can be done in a period or two with the help of the new technology, he said. "But it could take even a week sometimes to take a real expedition.’, "It's different from watching videos. You can actually move"，Taylor said during the lesson on farm animals. "Not only move, but also feel, said Richard Lamb. He studies how brains deal with information.“Your physiological responses（生理反应）in virtual reality are similar to what you get in doing the actual activity.”Lamb said.“Heart rate, breathing...everything.”

It is unknown how many classrooms will use the technology. But experts say it's still rare. Each headset can cost as little as＄20 or＄30，but systems and software for classes run into thousands of dollars. And good software is in great need. Another problem we face is how to make sure the VR technology mimics（模仿）the real world closely. "But we have to say VR technology provides students with a huge learning opportunity,”said David Evans, director of the National Science Teachers Association.

John Miller, a chemistry teacher，agreed. "Too often in schools, students did something wrong in their chemistry experiments. But we don't have enough materials for them to redo the experiments. In virtual reality, all they do is hitreset on the computer. We don't have to actually use chemicals.”Both Miller and Evans stressed the technology could enrich-not replace-real-world experiences. "We have to remain anchored（立足）in the real world,”Evans warned, "because that's the one that we really need to study and explain.”

【题目】 Global warming is happening all around us. This experiment helps you learn how a greenhouse works, and how greenhouse gases influence the earth’s atmosphere (大气).

What You Need:

Two thermometers

A notebook

A pencil or pen

A clear container

A watch or clock

A sunny area

What You Do:

1. Put the thermometers in direct sunlight. Let them sit in the sun for three minutes.

2. Draw two columns (栏), “Thermometer A” and “Thermometer B”, in the notebook.

3. After the three minutes, read and record the time and temperatures in the notebook.

4. Place one of the thermometers in the container and close it tightly.

5. Record the temperatures of the thermometers every ten minutes.

6. Discuss how the container influences the temperature.

What’s Going On?

The temperature outside the container is changing, as the warm air mixes with the passing cooler air. The air inside the container can’t mix with the air outside — it just gets warmer as the sunlight heats it up. A greenhouse works in a similar way: sunlight creates heat that can’t get out of the glass.

【1】What do you need in the experiment?

A.A dark room.B.A paper box.C.Some water.D.Two thermometers.

【2】How often do you record the temperatures of the thermometers?

A.Every five minutes.B.Every ten minutes.

C.Every fifteen minutes.D.Every twenty minutes.

【3】What can you learn from the experiment?

A.When the glass breaks.B.Why the sunlight is helpful.

C.How a greenhouse works.D.What the temperature changes.

【题目】--- Yummy! The fish tastes good.

--- .
