1托福閱讀經(jīng)典加試——鳥鳴
在托福考試中,，閱讀部分的加試成為了許多考生關(guān)注的焦點,。本文將圍繞鳥類的鳴叫能力展開討論，分析其是先天遺傳還是后天習(xí)得,，并通過實驗進行驗證,。這些內(nèi)容將幫助考生更好地理解相關(guān)知識，并為考試做好準(zhǔn)備,。
Although all birds can sing, the melodies and tunes they produce vary widely. To investigate whether their singing skills are a result of genetic inheritance or environmental learning, researchers have conducted several experiments on the chaffinch and the North American white-crowned sparrow.
Experiment 1: Researchers took a newly hatched chaffinch away from its nest and raised it in isolation, preventing it from hearing adult chaffinches sing. After three months, when it was time for the male to court, they returned it to nature to observe its song. The results showed that the chaffinch could still sing, albeit with a dialect variation that was simple and disconnected. This indicates that chaffinches possess an innate ability to sing.
Experiment 2: In contrast, a newly hatched white-crowned sparrow was also raised in isolation from adult birds. During the first three months, before developing its own song, it was exposed to recordings of other birds singing. It quickly learned the songs from the recordings, suggesting that its dialect is significantly influenced by environmental factors rather than genetics. However, after four months, it could only sing its own tune and was unreceptive to new recordings, indicating a time limit on learning.
Experiment 3: Another bird species, starting with the letter "F," was studied. These birds could only produce fragmented sounds instead of complete songs if they did not hear their own voices. They need to hear themselves to develop proper singing skills.
Vocabulary: ultimately, reinforce, proliferation, superb, optimal, blur.
Conclusion: The findings from these experiments reveal important insights into the nature of bird songs. While the chaffinch demonstrates an innate singing ability, the white-crowned sparrow's song is heavily reliant on environmental influences. Understanding these differences is crucial for TOEFL test-takers as they prepare for reading comprehension questions related to this topic.
