【解析】本文是一篇記敘文。主要介紹了美洲烏鴉的特征、習性以及和渡鴉的區(qū)別。

【1】“If you live in the United States, you’re almost ___1___(certain) seen at American crow(烏鴉).” 句子結構完整，不缺少成分，seen為動詞，應用副詞修飾動詞，故填certainly。

【2】“As___2___adult, this bird is entirely black from bill to tail, except for its brown eyes.” as為動詞，adult為名詞，因此，橫線處應使用冠詞修飾名詞。故填an。

【3】“These___3___(noise) birds are often recognizable by their special, loud cry, called a caw.” 句子結構完整，不缺少成分，birds為名詞，應用形容詞修飾名詞，故填noisy。

【4】“There are often mistaken___4___the common raven(渡鴉)”根據(jù)前文美洲烏鴉特征與后文渡鴉特征存在差異，可推斷出美洲烏鴉常被誤認為渡鴉。“ be mistaken for…”被誤認為… ，故填for。

【5】“but ravens are___5___(large),” 由前文可知，該句表示渡鴉與美洲烏鴉兩者之間體型的對比關系，所以應該用比較級，所以橫線處應該用形容詞的比較級形式。故填larger。

【6】“Both members of a breeding pair help build the nests, and the female crow usually___6___(lay) four or live eggs in spring or summer.” 主語為the female crow，屬于第三人稱，usually表通常情況，故填lays。

【7】“Crows sometimes stay near the spot___7___they were born to help raise other young crows.” 先行詞為spot，表示具體地點，并在從句中做狀語，故填where。

【8】“They prefer open areas with access to trees and they can sometimes ___8___(find)around vegetable gardens.”they與find之間是被動關系，橫線前有情態(tài)動詞can，所以應該用be+被動語態(tài)的形式，故填be found。

【9】“Crows also frequently live in suburban____9____(neighbor) and in parks.” and連接兩個并列結構。 parks為名詞復數(shù)，suburban為形容詞修飾橫線處名詞，故填neighborhoods。

【10】“Crows are considered ___10___(be)very intelligent birds.” crows與consider之間是被動關系，“ be considered to be…”被認為…，故填to be。
