Question

    Feeding birds is a popular way to watch wildlife.But experts say it might put wild birds at risk.

Feeding birds is not necessary for their survival except in extreme weather conditions.Feeders(喂食器)can definitely help birds get through that kind of weather.But most birds eat insects and show little interest in bird feeders.For those birds，we can grow native plants in a natural environment.Birds which are fond of eating seeds will be more likely to come to feeders if there is some cover nearby.This lets them feed and then fly to protective areas，such as in trees.

The most common mistake people make with their bird feeders is that they put feeders in places where birds are easily frightened by passers-by，risk being hurt by cats，or risk flying into windows.

So set up a bird feeder at least one meter away from a window.That way，if a bird gets frightened，it won’t get killed when it hits the glass.Owners of cats should keep them inside home so they can’t hurt the birds.

Some birds are more aggressive at feeders.They eat a lot and do not leave much food for other birds.A solution is to put the food in more than one place by using different kinds of seeds or fruits.This can also increase the number and diversity of birds in your neighborhood.But don’t feed wild birds anything salty，like potato chips，or food that could choke them，like bread.

Pay attention to food quality and freshness.Unprotected food left too long in feeders will turn moldy(发霉)，which can kill wildlife.

Another word of advice:Always provide a supply of clean water for birds，but use care when looking for the right birdbath.If the birdbaths are too deep for birds，putting a few large stones in the water can give the birds a place to sit.

本文是一篇说明文，人们在喂鸟的时候无意中会给鸟儿带来危险，文章具体解释了这些危险并提出了安全喂鸟的建议。

1.细节理解题。根据文章第三段“The most common mistake people make with their bird feeders is that they put feeders in places where birds are easily frightened by passers-by，risk being hurt by cats，or risk flying into windows.”可知人们在喂鸟的时候，最常见的错误是把喂鸟器放在错误的地方，这样给鸟儿带来了很多危险。故A项正确。

2.细节理解题。根据文章倒数第三段最后一句“But don’t feed wild birds anything salty，like potato chips，or food that could choke them，like bread.”可知作者建议人们不要喂给鸟儿薯条和面包，因为这些食物不适合喂鸟。故B项正确。

3.推理判断题。根据文章第五段第三句“A solution is to put the food in more than one place by using different kinds of seeds or fruits.”可知作者建议我们把食物放在多个地方，并提供不同种类的食物。这样做，自然是要增加喂鸟器的数量。故A项正确。

4.主旨大意题。根据第一段“Feeding birds is a popular way to watch wildlife. But experts say it might put wild birds at risk.”可知本文主要讲述的是喂鸟会给鸟儿带来一定的危险；第三段介绍了具体的危险，后四段里提出具体的安全喂鸟的建议。故D项“How to feed wild birds safely and healthily”符合本文中心思想，故选择D项。
