最新博士英语作文范文经典35篇 1. Television Program and Their Effect on children Television programs regularly entertain, educate, effect and even frighten the majority of our children. Most children are allowed to watch whatever program is on, with little thought on the effect that particular show will have on a child. Most programs can be classed as beneficial or harmful, according to what effect the program might have on a child. The beneficial television programs are mainly thouse that educate the young. There a re often specials on animal life. A few regular children’s programs develop the child’s interest in school-type learning by stressing numbers and the alphablt, and that encourages him or her to be creative. The beneficial commercials, such as those on anti-smoking, anti-litter, and health, should be included in this category. On the opposite side are the shows, which are generally harmful to children. Many commercials, especially those sponsoring the children’s programs, are deliberately written to create a desire for an unnecessary product such as sugar coated cereals and candy. All adult programs that include violence or sex scenes can at best fill a child’s mind with confusing or misleading ideas, and could possib ly harden the child to violence. Thoughtful parents will definitely not allow their children to view the bad programs. A child’s viewing time should be limited to watching educationlly benefical programs. 2. How to Solve the Housing Problem in Big Cities With the development of modern industruy, more and more people are flowing into big cities. Accordingly, the housing problem in big cities is becoming more and more serious. People have offered many solutions to this problem. I think building satellite cities in the suburbs is more practical. The fresh air and beautiful secnery in the suburbs will be appealing to the city citizens, who suffer from air pollution, noises, etc. in the overcrowded city. With more people leaving the city, more space will be available for those remaining. The housing problem in big cities will thus be solved. 3. “The younger generation knows best” Old people are always saying that the young are not what they were. The same comments is made from generation to generation and it is always true. It has never been truer than ti is today. The young are better educated. They have a lot more money to spend and enjoy more freedom. They grow up more quickly and are not so dependent on their parents. They think more for themselves and do not blindly accept the ideas of their elders. Events, which the older generation remembers vividly, are nothing more than past history. This is as it should be. Every new generation is different from the one preceded it. Today the difference is very marked indeed. The old always assume that they know best for the simple reason that they have been around a bit longer. They don’t like to feel that their values are being questioned or threatened. And this precisely what the young are doing. They are questioning the

考研英语作文经典范文 对于今年考研复习的学生来说。已经到了开始好好复习写作的环节了。 我也在暑假的时候，结束了一个班的写作的授课。 也在今天，结束了另外一个强化段的写作的授课。 我在所有的课堂上，讲解地核心的理念大概可以概括如下： 写作就是不犯错。先得分，再高分。 可能是因为，自己说地还不够透彻，或者是因为自己说地次数并不够多。 依旧有很多很多的学生，会直接间接的问到我各种各样关于写作复习的问题。 其中，绝大多数，都集中在“模版”，“要不要背范文”，“现阶段要不要开始练习真题了？”等吧。 我一一的进行一下简单的解释。
关于模版，是被妖魔化地最严重的。 一方面，学生很喜欢模版，因为，所有人都有一种想要走捷径的想法。 如果只需要背诵一篇模版，上考场之后，直接不需要思考，就写上去，然后，还能够得分，岂不是万事大吉。 但是，这个其实，就是拼一个概率的问题。 万一老师蒙对了，万一你刚好背会了，那么这两种可怕地极低的概率的事件，结合到一起，就会有一个非常理想的结果。 但是，这种概率，其实和一个人一辈子被雷劈中两次的概率是一样的。 其实，所有想要走捷径的人，最终都会发现，这是一条死路。 真正的捷径只有一条，那就是不走弯路。
另外一种学生，就是过度地将模版妖魔化。说某某老师说，只要使用模版就一定不给分，就给绝对的低分。 其实，要么就是这个老师并不懂考研写作，要么，就是这个老师所说的，作为学生的你，只听了自己想要听的那一部分内容。 其实，本质上，我们是所有人都是不听劝的。我们在基因上，生理上，只是喜欢，听那些自己认同的东西。 毕竟，认知的舒适区，才是真正的温柔乡。 我先说一下，什么样的文章会得0分。 1、偏题。 2、用别的语言写。 偏题很容易的。对于，只背诵模版的学生来说。原因也很简单，因为他们只背诵了一篇文章，所以，根本不审题，题目中的要求，什么也不看，直接写自己会的那些内容。自然无法：包含内容要点。 用别的语言写，也是会得0分的。有些学生，觉得自己很聪明，个别单词实在不会写了，就用拼音写。哈哈，以为我们阅卷的时

_______ _____________________________________________________________________ ________Thank you.：答案Attention, please! I'm going to give you a summary of today's discussion about whether we should go on line in our spare time.Many students think we can go on line as much as possible in our spare time because we are free then. Through the Internet, we can gain plenty of the newest knowledge and the latest information at home and abroad. What's more, network offers us a convenient way to communicate with each other. The Internet makes our lives outside class colorful and various.On the other hand, a few students partly agree to this idea. Going on line is part of our daily life. But they suggest a time limit. They've found that more students are playing computer games or chatting instead of studying their lessons or looking up materials. There are a few students who are often absent from school in order to go on line for fun.Thank you!2.假设你叫李华， 是一家英文杂志社的心理咨询师。某中学生小王给你写信，提到自己偏胖，想节食减肥，征求你的意见。请你给她回一封信，谈谈你对该问题的见解。内容要点． 如下：．健康比漂亮更重要；1．学生以学习为主，不要过于注重外貌和别人的看法；2．可通过多锻炼身体保持健康，要改变不良的饮食习惯；3．健康的心态也很重要。4．短文必须包括所有内容要点，可适当发挥；1注意： 心态．参考词汇：state of mind 3 2．词数：100左右。
