【TPO例句】

1. Early in his research, Kramer found that caged migratory birds became very restless at about the time they would normally have begun migration in the wild. (TPO11-P2)

在研究早期,Kramer发现被关在笼子里的侯鸟同往常去野外开始迁徙的时候变得焦躁不安。

2. Furthermore, he noticed that as they fluttered around in the cage, they often launched themselves in the direction of their normal migratory route. (TPO11-P2)

而且,他注意到,当这些鸟在笼子里躁动不安时,它们通常会飞向迁徙路径的方向。

3. He then set up experiments with caged starlings and found that their orientation was, in fact, in the proper migratory direction except when the sky was overcast, at which times there was no clear direction to their restless movements. (TPO11-P2)

于是,Kramer用星椋鸟做实验,将它们关在笼子里,总结出了它们的迁徙方向,事实上,它们基本都能朝向正确的迁徙方向,阴天除外,因为阴天的时候它们的骚动不安使得它们难以清楚分辨方向。

4. To test the idea, caged night-migrating birds were placed on the floor of a planetarium during their migratory period. (TPO11-P2)
