阅读下文，完成以下问题。美国华盛顿大学研究人员在《科学》杂志上发表报告说，尽管人类活动对于气温的全国上升确实起了作用，但是这种气候变化绝大部分要归咎于自然原因。他们对北半球近一个世纪以来的温度变化所作详细研究的结果表明，联合国和其他国际组织近来在一些报告中对全球气候变暖原因的解释是靠不住的。报告的主要作者，担任华盛顿大学、国家海洋和大气管理局大气和海洋联合研究所所长的约翰·华莱士说：“我们所作的研究已经清楚地表明全球气候的不断变化，是怎样引起气候的短期变动的。反过来，这种变动又有助于我们更好地了解大气层的温室效应(大部分是由于燃烧矿物燃料产生的二氧化碳引起的)可能引起的气候变暖的程度。”他告诫道，不能因为这个结果而放松对人类破坏环境行为的注意。这些气象学家说，从1975年至1990年间，北半球冬季气温(特别是美国的阿拉斯加、加拿大北部和俄罗斯等地)上升了0.3℃。他们认为这一气温上升有1/3是由大气环流的自然变动引起的。他们还认为，北半球地区从1900年至1990年近一个世纪以来的月温差约有一半也是由这种变动引起的。华莱士说：“尽管人类活动与气温的全面上升可能也有关系，但是我们认为，这种气候变化绝大部分应归因于自然变动，与温室效应引起的气候变暖无关。由于地表吸收热量的能力(热容量)比海洋低得多，地表冬季和夏季的温差非常大。 因此， 当大气环流带动暖气团吹过北半球各大陆以及冷气团吹过海洋上空时，北半球的平均气温往往比较暖和。”他说，尽管科学家们尚不完全了解引起大气环流型式变化的真正原因，但他确信这与自然变化有关。 从上面这段文字来看，华莱士他们的研究成果是（）。
Steven, as well as his classmates, (enjoy)（）playing football. They like this game.
It is, everyone agrees, a huge task that the child performs when he learns to speak, and the fact that he does so in so short a period of time challenges explanation.Language learning begins with listening. Individual children vary greatly in the amount of listening they do before they start speaking, and late starters are often long listeners. Most children will "obey" spoken instructions some time before they can speak, though the word "obey" is hardly accurate as a description of the eager and delighted cooperation usually shown by the child. Before they can speak, many children will also ask questions by gesture and by making questioning noises.Any attempt to trace the development from the noises babies make to their first spoken words leads to considerable difficulties. It is agreed that they enjoy making noises, and that during the first few months one or two noises sort themselves out as particularly indicative of delight, distress(痛苦), sociability, and so on. But since these cannot be said to show the baby’s intention to communicate, they can hardly be regarded as early forms of language. It is agreed, too, that from about three months they play with sounds for enjoyment, and that by six months they are able to add new sounds to their repertoire (能发出的全部声音). This self-imitation leads on to deliberate (有意识的) imitation of sounds made or words spoken to them by other people. The best title for this passage would be（）
