1、 Why are girls not as good at maths and science? Girls dont do as well at maths and science as boys. There are several reasons for this. The first and most important reason is that they arent encouraged to play with toys that build up interest in maths and science problems and that build skills for
2、problem solving or understanding how things work. Girls are encouraged to play with toys that foster language and human relations skills. As a result, they can grow up not knowing how an engine works or how to build a model from directions.Second, studies have shown that teachers dont expect girls t
3、o be good at maths. Even female maths and science teachers pay more attention to boys in class and call on boys more often. Becauseteachers dont expect girls to excel, they dont try very hard, and soon girls are far behind boys in these studies. Finally, girls dont have many role models to look up t
4、o. Not very many maths and science teachers are women, especially in the later grades. When the media picture mathematicians and scientists, they usually picture men. As a result, girls arent inspired to choose these fields as careers. In summary, several factors work together in the home, in school
5、s, and in society at large to send a subtle message to girls. Girls almost always get the message; as a result, few girls excel at maths and science. 有偿搭车“上班族”借助网络发帖联络搭乘“顺风车”，这种出行方式(trip mode, transportation)最近在北京、上海、深圳等一些大中型城市开始流行起来。一些网站还专门设立了相关的栏目，北京出现了全国第一家顺风车专业门户网站，有需求者只要将自己的出发地和目的地发布上网，就会很容易获得理
6、想的搭乘机会。除此之外，也有一些搭乘者是通过朋友介绍认识的。与国外一些国家搭顺风车现象有所不同的是，按事先约定，国内的一些搭乘者会以现金或实物的形式给车主一定的补偿，而一些车主也将省钱和挣钱作为提供便利的目的之一。面对越来越多的汽车污染以及日渐严重的交通压力，“顺风车”的出现无疑是件好事。但随之而来的“有偿搭车”现象却引起了各方的不同看法。对此持赞同意见的人认为应该提倡这种做法，因为它既方便了乘车人，也减轻了车主的经济负担，同时还能缓解城市交通压力；反对的人则认为私家车收费搭乘他人，严格意义上属于非法营运，由于它没有办理任何证件，干扰了正常的客运市场。政府应加以严格管理；一些保险公司相关人士还
7、认为，一旦发生事故，保险公司有权拒赔，理由是营运车风险比较大，同类型汽车的保险费收费标准，营运车辆要高于私家车。1-中美两国生意人在商务沟通方式上的区别I think there are at least two differences in the way of business communication between Chinese and American businesspeople. First, Chinese businessmen tend to have business negotiations in a rather indirect manner, as oppos
8、ed to the more direct manner of American businesspeople. The Chinese take time to learn if their prospective business contacts are really reliable, for example, by inviting them to a party and socializing with them. In contrast, American usually act with the “get-down-to-business-first” mentality. S
9、econd, the decision making process of Chinese companies is generally slow and time-consuming. This is because most Chinese companies keep to the “bottom-up, then top-down and then bottom-up” decision-making principle which involves many people at different levels. American companies, on the other ha
10、nd, usually operate with quick decision made by the top management. I hope American businesspeople in China will understand these differences in business practices and adjust the Chinese way.2-中美管理模式的区别I would say the American-type, or the top-down, management emphasizes efficiency, and competition
11、among workers, while the Chinese-type management gives priority to careful planning and encourages cooperation among workers, and between workers and the management. Thus, while the American-type management often frustrates many workers, the Chinese-type management gives workers a joy of participati
12、on and fulfillment, and s sense of pride in their work.3-中美员工的工作态度区别I think most Chinese view work as essential for having membership in a community. They believe that work allow them to have a sense of belonging in a community. In other words, work is necessary for them to gain social acceptance in
13、 the society. That is why many Chinese managers and employees work so hard to maintain their position in their company. Also, they see work as the most important thing in life. That is, they have tried to find the meaning of life through their jobs. While the Chinese work ethic is based on social pr
14、essure and community belonging, the American work ethic seems to be more individual oriented. Traditionally, we work because it is the will of God, and we often value the results and accomplishments of work more than its process. By the way, Im very impressed by the obvious strong sense of dedicatio
15、n to the jobs among the older Chinese employees.4-评价中美不同经营之道的利弊It is difficult to decide which is better than which, because there are some merits and demerits to both types of management. My suggestion is that people of both countries should learn from each other. I will say that in recent years, t
16、he merits of the Chinese way, or rather, the Oriental way, of management are beginning to be recognized by an increasing number of people in the West. This more humane Oriental way of management seems to offer a great deal to the executives of our American industries.三种错误的饭后习惯医生提醒人们，随着人们生活水平的逐渐提高，人们
17、的保健意识也随之增强了，许多人认为饭后吃点水果是现代生活的最佳搭配。无论是在餐厅、饭店，还是在家里就餐，许多人都喜欢饭后吃点水果爽爽口，其实这是一种错误的生活习惯，因为，饭后马上吃水果会影响消化功能。医生解释说，由于食物进入人们的胃以后，必须经过一到二小时的消化过程，才能缓慢排出。如果人们在饭后立即吃进水果，就会被先期到达的食物阻滞在胃内，致使水果不能正常地在胃内消化，在胃内时间过长，从而引起腹胀、腹泻或便秘等症状。如果人们长期坚持这种生活习惯，将会导致消化功能紊乱，因此，人们最好在饭后 12 小时再吃水果。医生还提醒说，人们还要注意改正饭后饮茶和饭后散步的错误习惯。饭后立即饮茶茶水会冲淡胃液
18、，影响胃内食物的正常消化。茶水中含有的单宁酸还会促使胃内的物质凝固，影响蛋白质的吸收，从而增加了胃的负担。对此，医生建议人们，在吃饭一小时内最好不要饮茶，应待饭后一小时胃内食物消化得差不多时再饮用茶水，这样对消化功能和物质凝固也不会产生太大的影响。“饭后百步走，活到九十九”，这种说法也是不科学的。人的胃在饭后是处于充盈状态的，即使是非常轻微的运动也会使胃受到震动，从而增加了胃肠负担，影响消化功能。对此，医生建议，饭后适当休息 30 分钟，待胃内的食物适当消化后，再活动较为适宜，这样也不会对消化系统产生太大的影响.why do we have eyebrows？Our eye brows pla
