推荐以下主题，有范文，还是要适当修改哦~1.文化冲击（经典主题）ModuleRecent years have witnessed an increasing number of people going abroad for academic or business reasons. Many of them experience culture shock, or the difficulty to adjust to a new culture that differs from their own. In this essay, an endeavor is made to probe into the causes and effects of this shock and render some suggestions to minimize it.In a multi-cultural context, culture shock, as the psychological (and sometimes physical) discomfort, is usually caused by unsuccessful encounters with the members of another culture. Many factors contribute to it- smells, sounds, flavors, the very feeling of the air one is breathing. Of course, the natives' unfamiliar language, behavior and different rules of social interaction trigger it as well. It is true that once outside of their own culture, the vast majority of cross-cultural visitors may begin to realize that there is a common uncertainty among them, as foreigners. Subsequently, this uncertainty and shock can sometimes affect their emotional, behavioral and psychological ability to think and function, possibly leading to unpleasantness, frustration, loneliness and insularity along with the confusion and disorientation.As culture shock is caused by multifaceted factors and potentially harmful to a person's wellbeing, its effects can be mitigated properly. Here are a few remedies that work for most people. Firstly, you should prepare for international travel by learning cultural values, customs, traits and the new language before hand.Secondly, find common interest within the new culture and develop an active hobby (tennis, volleyball ping pong) that will offer an outlet to release the feelings of disorientation, frustration and confusion. In addition, try to travel around to historical sites or familiar places within the culture in order to establish contact with local people or tourists.In conclusion, it is clear that because of the different thinking style and lifestyle, going abroad is easy to make international travelers suffer culture shock. If left untreated, it can lead a "culture crosser" to reject the inhabitants of the new country and isolate him or her from contact with locals. Therefore, people should be fully culturally prepared to deal with the perils of culture shock before setting foot on a different land.2.身体健康方面（关注不同角度，比如儿童肥胖问题ModuleChildhood obesity is already epidemic in some industrialized countries and on the rise in China. It is estimated that approximately 30 percent of children and teenagers in Beijing are overweight, 10 percent of whom are obese. There is convincing evidence that overweight or obesity may result in a host of health conditions. The prevalence of obesity in children has become a focus of public interest,What lies behind the prevalence of teenage obesity?Some research suggests that the increased incidence of obesity in children and adolescents stems from a variety of factors, including physical inactivity, sedentary behavior, heredity, eating habits and environmental factors. As we all know, modern technology and changes in lifestyle have created a society where people are becoming less physically active and increasingly sedentary. Some children indulge in inactive leisure pursuits, for example, TV viewing, net-surfing and gaming. Genetics are another major contributing factor. Just as the old saying goes, "Like father, like son." If parents are both overweight, their children have 80 percent chance of becoming overweight. An increase in the consumption of high fat and high energy foods is likely to be foremost among the causes of the current epidemic.What can we do to combat childhood obesity? There is a simple solution to the prevailing weight problem--eating a balanced diet and leading a physically active lifestyle. Children should be encouraged to try to eat a variety of foods, especially pasta, rice, bread, and other whole-grain foods, apart from plenty of fruits and vegetables. At the same time, the time spent in sedentary activities, e.g. watching TV, playing video and computer games should be decreased, We should always keep in mind that physical activity is important for physical health, emotional well-being, and achieving a healthy weight,In conclusion, for most children who are overweight or obese, the safest and most effective way to lose weight and keep it off over time is to eat less and exercise more.3.教育问题（结合最新发生的事件进行论述）ModuleIn the last several years the impact of video games, both positive and negative, on children has been a subject of both heated debate and scientific research. In this essay, I will examine both sides of the argument and establish my own standpoint.Some scientists argue that video games can have a positive influence on children. For example, they may be a friendly way of introducing children to computers, and stimulate children s curiosity and interest in the computer science, which leads to discovery and creativity. Besides, they may increase children's hand-eye coordination and attention to detail. In other words, gaming develops adaptability and flexibility. Also, researchers have found that the games can provide opportunities for achievement,freedom and even a connection to other players. Undoubtedly, playing with friends can be an enjoyable social interaction.On the other hand, scientific research has shown that playing video games may affect some children's physical functioning. Effects range from triggering epileptic seizures to causing heart rate and blood pressure changes.Furthermore, numerous studies suggest that playing a lot of violent video games is related to having more aggressive thoughts, feelings, and behaviors. Ample evidence also shows that spending large amounts of time playing these games can create problems and lead to poor social skills and lower grades. In addition, they can also be quite addictive, which is detrimental to children who lack self-control and self-discipline.While video games can be valuable learning tools, they also have some adverse effects. Regarding content, educational games are likely to have positive effects and violent games are likely to have negative effects. The point is that, in this new age of technology, children are spending much more time playing video games and watching television. And many of the video games contain some violence.Therefore, for decreasing the negative impact that gaming might have on children, parents should be most concerned about two things: the amount of time that children spend, and the content of the games that they play.Video game addiction has become a focus of public interest. Numerous studies suggest that heavy gaming exerts disastrous effects on children' s healthy growth and therefore some researchers and scholars propose that teenagers should not be allowed to play PC games, While l admit that computer games have a negative impact on the development of children, especially contributing to aggressive and anti-social behaviour, I still feel that it is irrational and impractical to ban video games.To start with, PC games may be a friendly way of introducing children to computer science. Playing computer games arouses curiosity, which leads to discovery and creativity, Some video games may promote learning, problem solving and help with the development of fine motor skills and coordination.Moreover, social skills are learned while children are enjoying various games. That is to say, playing computer games has become a way of associating with friends from all over the world. After all, playing with friends can be an enjoyable social interaction.Thirdly, playing computer games helps fulfill certain psychological needs, By this I mean, video games area useful outlet for childhood aggression because play allows kids to express feelings and impulses that have to be carefully held in check in their real-world interactions.In the final analysis, it is clear that the benefits of video games far outweigh the risks. I firmly believe that children should be encouraged to play computer games with adequate parental guidance because playful discovery is a doorway to learning.

1995, the American Film Technology Master Robert Zemeijishi shooting of the film "Forrest Gump," won the Oscar for best picture, best director, best adapted screenplay, and so six awards from Robert statement highly visible, a result, different from the Hollywood model of the types of movie. At that time, the United States immediately started a "Agam fever", the so-called "Agam fever" is the United States representative of the mainstream of social, cultural, from the mainstream ideology of the value orientation to the United States to face the hardships encountered in the heat determined. The movie "Forrest Gump" Winston Gelumu adapted from the novel of the same name, is an original full of ironic novels, from the anti-mainstream status, and the film is the story of a furnishing and landscaping, are on the on the mainstream ideology, it is the myth of the American people comforter, and this has undoubtedly more videos of the tastes of the audience and the judges, but the expense of the struggle against the original spirit of treason, the film has become a symbol of idealistic moral, the United States is "Hollywood" film factory values, also in line with the United States precisely the top of the mainstream consciousness. The story is about an IQ of only 75 children through their own efforts from the primary "running" to a secondary school, "running" to the university, then "running" to the Vietnam battlefield, the Vietnam War and then crazy "run" their love The story of a determined. I think this is the story of a false determined, although the film shows the 1950s -80 people in the United States and positive social image, but to know that the film society is not true behind the appearance of the film - that the 1950s to the 1980s the United States, blacks oppose racial discrimination, and anti-Vietnam War sentiment is plaguing the United States the upper class, and also people lose confidence in the future of the country and look forward to, in the face of the failure of the Vietnam War, the people of their own country, have been the fate of the future lost their fighting spirit, full of negative emotions confused, and the movie "Taxi driver" reflects the historical background, the keynote is the same. At this time, "Forrest Gump" is a panacea for economic soothe people, and the image of Agam is playing a mainstream and the mainstream anti-coordination between. In fact, the image through film, we can see that the United States at that time director Robert placed by the hope -- 1. Agam friendship with Bubba Bubba and Agam are the same soldiers participated in the Vietnam War, but Bubba is a black man. Directed by the Vietnam battlefield, Agam rescue Bubba, Bubba after growing friendship and Agam, to express the reality of the absence of ethnic conflict. It also carries their directors and the public to ease the aspirations of ethnic conflict. 2. Agam and Jennifer Love Agam since the Vietnam War back after Jennifer have degenerated, and led a dissolute life, Agam has been love Jennifer, but Jennifer is like a fan as missing, and later, Jennifer back into the embrace of the Agam, Agam and share weal and woe with the some time, and after Jennifer left, left, Agam Agam, in order to find Jennifer has been running, Wong paid off days later, Jennifer brought back and the son of Agam But this time Jennifer has had the incurable disease, will soon be dead. Through the bewildering love, the film reflects the trauma of peace and anti-war history and the absence of the women's liberation movement. Jennifer as an anti-war image in the mainstream, and to degenerate until the death of the possibility of not hope to achieve. I think here also carries their people for the fate of their country lost. 3. Agam and Lieutenant Dan Role in the Vietnam War, Agam two friends: a love of shrimp Bubba, it is an awesome Lieutenant Dan. Directed by Vietnam on the battlefield Agam Lieutenant Dan risking death to rescue a show to demonstrate to everyone in the mainstream society of the ideological and moral rescue. The film is not so much soothe the myth of the American people is not to say that this film is a great film that the American people. A film, then a feather Homelessness with the wind, struggling to shake Homelessness, the American public has faith in God Nietzsche is dead? Modern society people in the face of the era of mechanical reproduction really do not know what a collapse? People do not know the fate of the place where they believe they should not be the fate into their own hands, but should master by the wind and let their Homelessness, I think this is the American people face the destiny of a pessimistic mood bar. But even confused even confused, or to continue to live, there is still hope that everything, and it is also the upper mainstream of the United States of expectation. After all, human vulnerability is the need to soothe the soul, so in the clear theme of this film, we still believe that Hemingway's "this world is a good place, it is worth fighting for her." 1995年，美国电影技术大师罗伯特·泽梅基斯拍摄了影片《阿甘正传》，一举夺得了奥斯卡最佳影片、最佳导演、最佳改编剧本等六项大奖，从此罗伯特声明鹊起，也因此出现了有别于好莱坞模式化的电影类型。当时美国立即掀起了一股“阿甘热”，所谓“阿甘热”就是代表了美国主流社会文化，从主流意识形态的价值取向出发，来积极面对美国在遭遇磨难时的立志热。 影片《阿甘正传》改编自温斯顿·格鲁姆的同名小说，原著是一本充满了讽刺意味的小说，站在反主流的地位上；而影片则对故事进行了修饰和美化，是站在主流意识形态之上，它是抚慰美国民众的神话，这无疑使影片更合观众和评委的口味，但却牺牲了原著的叛逆斗争精神，使影片成为了一种理想化道德的象征，这也是美国“好莱坞”电影工厂的价值取向，恰恰也符合了美国上层的主流意识。 故事讲述了一个智商只有75的小孩通过自己的努力从小学“跑”了到中学，又“跑”到了大学，之后又“跑”到了越南战场，越战后又疯狂的“跑”自己的爱情的一个立志故事。 本人认为这是一个虚假立志的故事，虽然影片展现了50年代—80年代美国社会民众积极向上的形象，但要知道，影片背后真实的社会不是电影所呈现的那样——50年代到80年代的美国，反对黑人种族歧视问题、反越战情绪正困扰着美国的上层阶级，而民众也对国家的未来失去信心和期待，面对越战的失败，民众对自己、国家、未来的命运都已失去斗志，充满了消极迷茫的情绪，这和电影《出租汽车司机》所表达的历史背景、基调是一样的。 此时《阿甘正传》就是一济抚慰民众的良药，而阿甘的形象正是起到了一种主流与反主流之间的协调关系。 其实通过电影的表象，我们可以看到导演罗伯特对当时美国所寄予的希望—— 1． 阿甘与布巴的友谊 布巴和阿甘一样都是参加越战的军人，只是布巴是一个黑人。导演通过在越南战场上，阿甘营救布巴，之后布巴和阿甘的友谊与日俱增，来表现种族冲突现实的缺席。 这也寄托了导演以及民众缓和民族冲突的愿望。 2． 阿甘与珍尼的爱情 阿甘自越战回来以后，珍尼已经堕落，过着放荡的日子，阿甘一直深爱着珍尼，但珍尼像个迷一样失踪了，后来，珍尼回来投入了阿甘的怀抱，并与阿甘同甘共苦了一段日子，之后珍尼又出走了，出走之后，阿甘阿甘为了寻找珍尼一直奔跑，黄天不负有心人，后来，珍尼回来了并带来了阿甘的儿子，可是此时的珍尼已经得了不治之症，不久即将死去。 通过扑朔迷离的爱情，影片反映出了和平与反战的创伤历史以及妇女解放运动的缺席。 珍尼是作为一个反主流反战的形象出现的，而以堕落直至死亡说明了希望实现的不可能性。 我想这里也寄托了民众对于国家命运的迷茫。 3． 阿甘与丹中尉 在越战场上，阿甘有两个朋友：一个是爱捕虾的布巴，一个则是令人敬畏的丹中尉。 导演通过越南战场上阿甘冒死去营救丹中尉的一场戏，来给大家展示了意识形态中主流社会的道德拯救。 与其说这部电影是抚慰美国民众的神话电影还不如说这是一部寄予美国民众希望的电影。 影片一开始，一片羽毛便随着风飘零，摇摇摆摆地飘零，美国民众一直信仰的上帝尼采说是已经死了？现代社会的人们在面对机械复制时代的大崩溃真的是无所适从了么？民众不知道自己的命运该寄予何处，他们相信自己的命运不应该掌握在自己的手中，而是应该由风掌握，任由自己飘零，我想这也是美国民众面对国家命运的一种悲观情绪吧。 不过哪怕迷茫哪怕疑惑，生活还是要继续，一切都还是有希望的，这也是美国上层主流所期望的。毕竟人类脆弱的心灵是需要抚慰的，所以在这样主题明确的影片里，我们还是要相信海明威说的 “这世界是个好地方，值得为她奋斗。”
