长期以来，饮酒(spirits)在中国人的生活中一直扮演着重要的角色，无论是帝王还是百姓。饮酒是中国文化的一部分。中国人的祖先在作诗、写散文时喜欢饮酒，在宴会上还会向亲戚朋友敬酒。但饮酒不仅属于文化人，也是普通人生活中不可缺少的一部分。人们在各种场合饮酒，如生日宴会、饯行宴会、婚礼宴会(wedding banquet)等。在搬进新房或生意开业时，也会邀请朋友来吃饭、饮酒。

一些学者担心年轻人过分崇尚西方节日，而对中国传统节日的热情逐渐降温。

中国正与17个国家协商，要把高铁网络(high-speed railway network)延伸到这些国家。这些国家大多数矿产和能源资源都很丰富。这些线路将会按照中国高铁建设标准来铺设，最高时速可达到350公里。中国承诺为他们提供技术、设备和高速列车，甚至为那些愿意向中国提供自然资源的国家承担建设费用。目前，中俄两国已经就修建跨越西伯利亚(Siberia)的高铁路线达成了一致意见。

在中国，9月10日的教师节(Teacher's Day)是一个很重要的节日。这一天，人们用各种方式表达对教师的敬意。近年来，许多专家一直希望变更教师节的日期。一些研究中国传统文化的学者提出，教师节应该有其历史文化内涵。不久前，相关部门拟将教师节改至9月28日。那天被认为是孔子(Confucius)诞辰日。作为“先师”(First Teacher)，孔子是中国历史上最重要的教育家及哲学家。

When older people can no longer remember names at a cocktail party, they tend to think that their brainpower is declining. But a growing number of studies suggest that this assumption is often wrong. Instead, the research finds, the aging brain is simply taking in more data and trying to examine carefully a lot of information, often to its long-term benefit. Some brains do deteriorate with age. But for most aging adults, researchers say, much of what occurs is a gradually widening focus of attention that makes it more difficult to get hold of just one fact. Although that can be frustrating, it is often useful. "It may be that distractibility is not, in fact, a bad thing" said Shelley E Carson, a psychology researcher at Harvard "It may increase the amount of information available to the conscious mind" For example, in studies where subjects are asked to read passages that are interrupted with unexpected words or phrases, adults 60 and older work much more slowly than college students. Although the students plow through the texts at a consistent speed regardless of what the out-of-place words mean, older people slow down even more when the words are related to the topic at hand. That indicates that they are not just stumbling (结结巴巴地念) over the extra information, but are taking it in and processing it. When both groups were later asked questions for which the out-of-place words might be answers, the older adults responded much better than the students. "For the young people, it's as if the distraction never happened," said a researcher of the review, Lynn Hasher, a professor of psychology at the University of Toronto. "But for older adults, because they've retained all this extra data, they're now suddenly the better problem solvers. They can transfer the information they've soaked up from one situation to another." Such tendencies can yield big advantages in the real world, where it is not always clear what information is important, or will become important. For instance, a seemingly irrelevant point or suggestion in a memo can take on new meaning if the original plan changes.

If the salinity (含盐量) of ocean waters is analyzed, it is found to vary only slightly from place to place. Nevertheless, some of these small changes are important. There are three basic processes that cause a change in oceanic salinity. One of these is the subtraction of water from the ocean by means of evaporation—conversion of liquid water to water vapor. In this manner, the salinity is increased, since the salts stay behind. If this is carried to the extreme, of course, white crystals of salt would be left behind. The opposite of evaporation is precipitation (降水), such as rain, by which water is added to the ocean. Here the ocean is being diluted(稀释) so that the salinity is decreased. This may occur in areas of high rainfall or in coastal regions where rivers flow into the ocean. Thus salinity may be increased by the subtraction of water by evaporation, or decreased by the addition of fresh water by precipitation or runoff (形成地表水部分的降雨). Normally, in tropical regions where the sun is very strong, the ocean salinity is somewhat higher than it is in other parts of the world where there is not as much evaporation. Similarly, in coastal regions where rivers dilute the sea, salinity is somewhat lower than in other oceanic areas. A third process by which salinity may be altered is associated with the formation and melting of sea ice. When seawater is frozen, the dissolved materials are left behind. In this manner, seawater directly beneath freshly-formed sea ice has a higher salinity than it did before the ice appeared. Of course, when this ice melts, it will tend to decrease the salinity of the surrounding water. In the Weddell Sea, off Antarctica, the densest water in the oceans is. formed as a result of this freezing process, which increases the salinity of cold water. This heavy water sinks and is found in the deeper portions of the oceans of the world.

在第7届 中国-东盟首脑会议 (China-ASEAN Summit)上，温家宝倡议，从2004年起每年在中国广西南宁举办 中国-东盟博览会 (China-ASEAN Expo)。他的提议受到东盟各国领导人的欢迎。设立博览会的目的是争取中国和东盟各国的互惠互利、共同繁荣。十年来，博览会极大推动了区域经济和贸易合作，为世界各地的商界带来了巨大机遇。今年，2300多家来自中国和东南亚国家的公司参加了展会。

One principle of taxation, called the benefits principle, states that people should pay taxes based on the benefits they receive from government services. This principle tries to make public goods similar to【C1】______ goods. It seems reasonable that a person who often goes to the movies pays more in【C2】______ for movie tickets than a person who rarely goes. And【C3】______ a person who gets great benefit from a public good should pay more for it than a person who gets little benefit. The gasoline tax, for instance, is sometimes【C4】______ using the benefits principle. In some states, 【C5】______ from the gasoline tax are used to build and maintain roads. Because those who buy gasoline are the same people who use the roads, the gasoline tax might be viewed as a【C6】______ way to pay for this government service. The benefits principle can also be used to argue that wealthy citizens should pay higher taxes than poorer ones, 【C7】______ because the wealthy benefit more from public services. Consider, for example, the benefits of police protection from【C8】______. Citizens with much to protect get greater benefit from police than those with less to protect. Therefore, according to the benefits principle, the wealthy should【C9】______ more than the poor to the cost of【C10】______ the police force. The same argument can be used for many other public services, such as fire protection, national defense, and the court system.A) adapt I) providedB) contribute J) revenuesC) exerting K) similarlyD) expenses L) simplyE) fair M) theftF) justified N) totalG) maintaining O) wealthH) private
