题目内容
Some people associate migration mainly with birds. Birds do travel vast distances, but mammals also migrate. An example is the caribou, reindeer that graze on the grassy slopes of northern Canada. When the weather turns cold, they travel south until spring. Their tracks are so well-worn that they are clearly visible from the air. Another migrating mammal is the Alaska fur seal. These seals breed only in the Pribilot Islands in the Bering Sea. The young are born in June and by September are strong enough to go with their mothers on a journey of over 3,000 miles. Together they swim down the Pacific Coast of North America. The females and young travel as far as southern California. The males do not journey so far. They swim only to the Gulf of Alaska. In the spring, males and females all return to the islands, and there the cycle begins again. Whales are among the greatest migrators of all. The humpback and blue whales migrate thousands of miles each year from the polar seas to the tropics. Whales eat huge quantities of plankton. These are most abundant in cold polar waters. In winter, the whales move to warm waters to breed and give birth to their young. Which of the following is NOT true（）

进境流向报检是指法定入境检验检疫货物的收货人或其代理人持有关证单在卸货口岸向口岸检验检疫机构报检，获取《入境货物通关单》并通关后由进境口岸检验检疫机构进行必要的检疫处理，货物调往目的地后再由目的地检验检疫机构进行检验检疫监管。申请入进境流向报检货物的通关地与目的地属于不同辖区。

不属于“分异作用”的一项是( )。阅读下文，回答下面问题 原始地球形成后的八亿年，其内部逐渐变热使局部熔融并超过铁的熔点，原始地球中的金属铁、镍及硫化铁熔化，并因密度大而流向地球的中心部位，从而形成液态铁质地核。同时，地球的平均温度进一步上升(可达约2000℃)，引起地球内部大部分物质熔融，比母质轻的熔融物质向上浮动，把热带到地表，经冷却后又向下沉没。这种对流作用控制下的物质移动，使原始地球产生全球性的分异，演化成分层的地球，即中心为铁质地核，表层为低熔点的较轻物质组成的最原始的陆核，陆核进一步增生，扩大形成地壳。地核与地壳之间为地幔。分异作用是地球内部最重要的作用，它导致了地壳及大陆的形成，并导致大气和海洋的形成。所以说，我们的地球是原始地球再生的，这个再生过程大约发生在40亿年前(或者说是37亿年至45亿年前)，即我们已经发现的最古老岩石的形成时期之前。氢和氧合成的水，原先潜藏于一些矿物中。当原始地球变热并部分熔融时，水释放出来并随熔岩运移到地表，大部分以蒸气状态逸散，其余部分在漫长的地质历史进程中逐渐充满大洋。 在原始地球变热而产生分异作用的过程中，从地球内部释放出来的气体形成了大气圈。早期地球的大气圈成分与现在的不同，正是由于紫外线辐射的能量促使原始大气成分之间发生反应。从无机物质生成有机小分子，然后发展咸有机高分子物质组成的多分子体系，再演变成细胞，生命得以开始和进化。
Every group has a culture, however uncivilized it may seem to us. To the professional anthropologist, there is no intrinsic superiority of one culture over another, just as to the professional linguist, there is no intrinsic hierarchy among languages.People once thought of the languages of backward groups as undeveloped. While it is possible that language in general began as a series of grunts and groans, it is a fact established by the study of "backward" languages that no spoken tongue answers that description today. Most languages of uncivilized groups are, by our most severe standards, extremely complex. They differ from western languages not in their sound patterns or grammatical structures, which usually are fully adequate for all language needs, but only in their vocabularies, which reflect the objects and activities known to their speakers. Even in this aspect, two things are to he noted. First, all languages seem to possess the machinery for vocabulary expansion, either by putting together words already in existence or by borrowing them from other languages and adapting them to their own system. Second, the objects and activities requiting names and distinctions in "backward" languages, while different from the west, are often surprisingly numerous and complicated. A western language distinguishes merely between two degrees of remoteness "this" and "that". But some languages of the American Indians distinguish between what is close to the speaker, or to the person addressed, or removed from both, or out of sight, or in the past, or in the future. Most languages of uncivilized groups are （）.
