Mr. Jenner Weir is convinced that birds pay particular attention to the colors of other birds, sometimes out of jealousy and sometimes as a sign of kinship. Thus he turned a reed-bunting (Emberiza hoeniculus), which had acquired its black headdress, into his aviary, and the newcomer was not noticed by any bird except by a bullfinch, which is likewi black-headed_ This bullfinch was a very quiet bird, and had never before quarreled with any of its comrades, including another reed-bunting, which had not as yet become black-headed; but the reed-bunting with a black head was so unmercifully treated that it had to be removed.

Passage 2
counterbore
mwx什么意思 At the end of what emed a tedious while, I had managed to pack my head full of islands, towns, bars, "points," and bends; and a curiously inanimate mass of lamber it was, too. However, inasmuch as I could shut my eyes and reel off a good long string of the names without leaving out more than ten miles of river in every filly, I began to feel that I could make her skip tho little gaps. But of cour my complacency could hardly get start enough to lift my no a trifle into the air, before Mr. Bixby would think of something to fetch it down again. One day he turned on me suddenly with this ttler:
"What is the shape of Walnut Bend?"
He might as well have asked me my grandmother''s opinion of protoplasm( 原生质fur)。 I reflected respectfully, and then said I didn''t know it had any particular shape. My gunpowdery chief went off with a bang, of cour, and then went on loading and firing until he was out of adjectives.英语学习网站 voa
