答案：

现在飞越海洋是一件轻而易举的事情，然而几个世纪以前渡过海洋需要周密的计划、人造船只和勇气。是谁最先渡过了哪个海洋一直是科学家和历史学家研究的话题，最近研究结果发现鸡可能也是最早渡过玻利尼西亚和南美之间的海洋的。

41.D。主旨大意题。本文在第一段点题，根据第一段第四句“WhenitcomestothetripbetweenPolynesiaandSouthAmerica,chickensmayhavebeenamongthefirstoceanvoyagers,accordingtonewevidence.”并根据后面科学家对在玻利尼西亚群岛和南美洲挖出的鸡骨进行DNA鉴定等，可知D选项正确。

42.D。事实细节题。由文章第二段可知第一批从Polynesia到Chile的人是在大约620年前，而根据第二段最后一句可知，第一批欧洲人晚了大约一个世纪，因此他们是约在520年前到的南美洲的。

43.B。事实细节题。由文章倒数第三段“Theresearchersalsocomparedthegeneticmaterial,orDNA,fromtheSouthAmericanchickenbonewithDNAfrom11chickenbonesthathadbeenfoundonthePolynesianislandsofTongaandAmericanSamoa.”和倒数第二段可知科学家是通过对两地挖出的鸡骨进行DNA鉴定发现这个结果的。

44.D。事实细节题。由第二段第二句“Bythen,theIncapeoplewerealreadylivinginSouthAmerica...”可知theIncapeople在玻利尼西亚人到达南美洲之前，已经在那里居住了。

45.C。事实细节题。由第一段“Centuriesago,however,crossingtheopenseasrequiredthoroughandaccurateplanning,handmadeboats,andcourage.”可知，跨海之旅要有计划、有船，而且还需要勇气，所以答案选择C。

[答案解析]

21．A根据上下文可知，此处意思为：如果我们只需坐在电脑前而无需输入密码就可以自动登录该多好。A自动地；B个人的；C正确的；D偶尔的，临时的。

22．B由上文可知，因“用脸部识别技术来帮你登录”了，所以“不需要用密码”。

23．A由上文可知此处所选词的意思相当于上文中的login(登录)，故选A，存取(信息)，访问。

答案：

现在飞越海洋是一件轻而易举的事情，然而几个世纪以前渡过海洋需要周密的计划、人造船只和勇气。是谁最先渡过了哪个海洋一直是科学家和历史学家研究的话题，最近研究结果发现鸡可能也是最早渡过玻利尼西亚和南美之间的海洋的。

41.D。主旨大意题。本文在第一段点题，根据第一段第四句“WhenitcomestothetripbetweenPolynesiaandSouthAmerica,chickensmayhavebeenamongthefirstoceanvoyagers,accordingtonewevidence.”并根据后面科学家对在玻利尼西亚群岛和南美洲挖出的鸡骨进行DNA鉴定等，可知D选项正确。

42.D。事实细节题。由文章第二段可知第一批从Polynesia到Chile的人是在大约620年前，而根据第二段最后一句可知，第一批欧洲人晚了大约一个世纪，因此他们是约在520年前到的南美洲的。

43.B。事实细节题。由文章倒数第三段“Theresearchersalsocomparedthegeneticmaterial,orDNA,fromtheSouthAmericanchickenbonewithDNAfrom11chickenbonesthathadbeenfoundonthePolynesianislandsofTongaandAmericanSamoa.”和倒数第二段可知科学家是通过对两地挖出的鸡骨进行DNA鉴定发现这个结果的。

44.D。事实细节题。由第二段第二句“Bythen,theIncapeoplewerealreadylivinginSouthAmerica...”可知theIncapeople在玻利尼西亚人到达南美洲之前，已经在那里居住了。

45.C。事实细节题。由第一段“Centuriesago,however,crossingtheopenseasrequiredthoroughandaccurateplanning,handmadeboats,andcourage.”可知，跨海之旅要有计划、有船，而且还需要勇气，所以答案选择C。
