今天原文及范文解析，托福综合写作是写作部分的第一个题目，一般大家会阅读到一段文字，然后听到一段内容，两个内容是话题相关但是观点相反的，所以需要大家认真分析之后写作。
TASK 1 Integrated Writing
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.
Now listen to part of a lecture on the topic you’ve just read about.
None of the solutions you’ve read about will effectively stop birds from getting injured. First, replacing regular glass with one-way glass. Well, the problem with one-way glass is that to the bird on the outside, a one-way glass surface reflects just like a mirror. And a surface that reflects like a mirror is just as bad as regular glass for birds because birds don’t understand mirrors. If they see a reflection of the sky in a mirror or of a tree in the mirror, they think the reflection is the sky or is the tree and they’ll fly right into them.
The second solution, painting colorful patterns like stripes on regular glass, also has problems. As the reading said, these designs include openings so people inside the buildings can see out. But birds will perceive these unpainted openings as open holes. And if birds think they’re seeing holes, they will try to fly right through them. To prevent birds from doing this, the unpainted spaces in the window would have to be extremely small. But that would then make the rooms of the buildings too dark for the people inside them.
The third solution, creating an artificial magnetic field, won’t work very well, either. While it’s true that birds use Earth’s magnetic field to help them navigate, they use this only when they’re traveling very long distances. For example, if a bird is migrating from a cold country to a warm one during winter, it will use its magnetic sense to figure out which way it should fly. But this ability isn’t used to go over short distances such as going from one side to the city to another. For short trips, birds use their eyes and the brightness of light to determine where to go so magnetic signals from buildings won’t have much effect.

材料要点重现：lecture中教授的观点是阅读中的保护鸟类不受到来自玻璃的伤害的方法全都是无用的。原因有三点，第一是单向玻璃会被鸟当成镜子，它们还是会撞上去。第二是那些没有被涂成彩色的玻璃会被鸟当成是洞，一样会撞上去。第三是只有当长途飞行时比如迁徙，鸟类才会用地磁导航。
高分词汇：reflection, artificial, navigate
范文：
The reading mainly talks about that since glass is very dangerous to birds, so there are several ways to prevent from harming them. However the listening challenges what are stated in the passage by providing three strong reasons.
Firstly, in the reading, it is said that we can use one-way glass to replace the regular ones. In contrast, the listening holds a view that the surface of that kind of glass is like a mirror which can’t be understood by birds. That is to say, if they see a reflection of the sky or tree in a mirror, they’ll fly right into them.
Secondly, the passage asserts that we can paint some colorful lines or other designs on regular window glass. However, the professor maintains an opposite opinion that birds will consider those unpainted openings as open holes and they'll try to fly right through them. In case of birds doing so, the unpainted spaces in a window would have to be very small, but that would then make the rooms of the buildings too dark to stay in.
Finally, the author of reading passage believes that creating an artificial magnetic field to guide birds away from buildings. On the other hand, the professor disagrees it with the point that birds only use earth’s magnetic when they are travelling very long distances. To state if more clearly, birds can use their magnetic sense to migrate, use eyes and brightness of light to navigate for short trips.
