hopping为什么要双写p

因为这个是双音节，双音节是需要双写的。

动名词的规则变化

1 一般情况下，直接在动词后加－ing （现在进行时）work working study - studying

2 动词以不发音的－e结尾，要去－e加－ing take - taking make - making

3 重读闭音节的动词，要双写词尾字母，再加－ing cut - cutting put begin

4 以－ie结尾的动词，把变成y再加－ing lie - lying tie - tying

　Cues to find prey

　寻找猎物的线索

　Birds are known to use visual, auditory, and possibly vibrations or tactile cues to find prey, but vision is predominant.

　通常鸟儿们是通过视觉、听觉，有时可能是触觉(昆虫的振动)这些线索来寻找猎物，其中视觉居多。

　The way the robins turn their head when searching for food suggests they could be using visual or auditory cues, but it wasn?t until scientists tested robins in the lab that we really knew for sure how they find worms.

　Testing the birds

　测试鸟儿

　To test if they were using scent to locate their prey, birds were offered trays with buried live, moving worms and dead ones. Robins found the live worms more often, suggesting they were not using scent.

　为了测试鸟儿是否通过嗅觉寻找猎物，托盘里分别藏有活着的昆虫和死了的昆虫。知更鸟找出的多是活着的昆虫，这说明知更鸟寻找猎物时并没有利用嗅觉。

　In the next test, they were given hanging food trays to keep them from touching the soil with their feet and detecting the worm?s vibrations. The trays did not affect their ability to find the worms, suggesting they do not use tactile cues.

　下一个测试是：把托盘悬挂起来，这样知更鸟的脚碰不到泥土，也不能探测昆虫的振动。测试并没有影响知更鸟捕捉昆虫，这说明知更鸟寻找猎物时并没有利用触觉。

　Sound Cues

　声音线索

　When cardboard was used as a barrier to block visual cues, the birds could still find the worms. That meant they were using another sense. A last experiment used white noise to block sound cues and the birds had more difficulty finding the worms.

　用纸板作为障碍物破坏视觉线索，鸟儿依然能找到昆虫。说明鸟儿是用另种线索。最后的实验利用白色噪音破坏声音线索，鸟儿寻找昆虫困难起来了。

　The research concluded that robins could use either visual or auditory cues alone to find worms in the soil, but probably use both. So the next time you see a robin ?head-cocking? you can be fairly sure it?s listening and looking for those mouthwatering treats!

　研究结果是知更鸟可以利用视觉或听觉中任一线索寻找泥土中的昆虫，但是也很可能是两种皆有。所以，下次你再看见知更鸟在草丛中摇头晃脑的，你可以确定它们是通过听觉寻找垂涎的美味了!
