题目原文：
Glass is a favored building material for modern architecture, yet it is also very dangerous for wild birds. Because they often cannot distinguish between glass and open air, millions of birds are harmed every year when they try to fly through glass windows. There are, however, several solutions that responsible businesses can use to prevent injuries to birds.
One-Way Glass
One solution is to replace the regular, clear glass with one-way glass that is transparent in only one direction. The occupants of the building can see out, but birds and others cannot see in. If birds cannot see through a window, they will understand that the glass forms a solid barrier and will not try to fly through it.
Colorful Designs
A second solution is to paint colorful lines or other designs on regular window glass. For example, a window could have a design of thin stripes painted over the glass. People would still be able to see through the openings in the design where there is no paint, while birds would see the stripes and thus avoid trying to fly through the glass. Architects can be encouraged to include colorful painted patterns on glass as part of the general design of buildings.
Magnetic Field
The third solution is to create an artificial magnetic field to guide birds away from buildings. Humans use an instrument called a magnetic compass to determine directions—either north, south, east, or west. Bird research has shown that birds have a natural ability to sense Earth’s magnetic fields; this ability works just like a compass, and it helps birds navigate in the right direction when they fly. A building in a bird flight path can be equipped with powerful electromagnets that emit magnetic signals that steer birds in a direction away from the building.

教授：为了保护环境，政府应该做点什么来鼓励人们用电车？
Claire：多建电桩。
Paul：给电动车修专用道。
Doctor Achebe: As countries work to reduce emissions and protect the environment, many governments are encouraging the adoption of electric vehicles through new policies. This week we will discuss ideas for policies that could promote electric vehicle usage. In your post, I would like you to address this question: What policies should the government implement to promote electric vehicles for environmental protection?
Claire: More charging stations are key to getting people to buy electric cars. It’s frustrating when you can’t charge your car. The government should offer big tax credits to businesses to build charging stations. If charging spots are everywhere, range anxiety will go away and electric car sales will take off. We need that to help the Earth.
Paul: The government needs to create entire highways just for electric cars. These special roads could have charging stations along the way so range anxiety disappears. Exclusive electric highways would show electric cars are the transportation of the future. We’d see tons more Teslas on the road helping clear the air.
