雅思写作教育类话题的详解 　　雅思写作教育话题主要考察教育对个人的影响以及对国家社会的影响，但因前者居多，在写作过程中我们需以学生作为重点分析对象，下面我为大家带来关于雅思写作教育类话题的详解，供大家参考学习，预祝对您有所帮助! 　　当考察某种教育活动或者教学方法时，往往要关注四项发展和三大影响源。 　　雅思写作教育话题--四项发展： 　　身体(physical development) 　　智力(intellectual development) 　　道德及思想(mental development) 　　社会性发展(social development) 　　而它们主要来自三个影响源，即家庭、学校、社会(媒体)。 　　四大发展 　　身体健康：孩子们户外活动相对较少(insufficient outdoor activities)，并且花很多时间在电脑、电视、游戏等，因此会伤害视力(impair eyesight)，导致身体素质下降(lead to poor fitness)，甚至引起超重(overweight)。学习压力也会影响身体健康(often spend much time on study/face fiercecompetition so that they suffer from great study pressure). 　　智力发展：在校学习学术知识(academic knowledge)，从电视或其他途径中了解课外知识(extra-curriculum knowledge that students are interested in)，学生们可以扩宽视野(expand vision)和丰富知识(enrich knowledge)。不同科目会训练不同技能，例如数学-train logic thinking，艺术-relax frompressure， discover talents and develop potential，体育-build better physical condition， learnteam spirit， 语言-learn more cultures， more competitive when looking for a job， easier toadapt to the globalized world. 　　道德及思想发展：遵守规则(obey school rules， learn basic code of conduct)，判断是非(judgeright and wrong)，尊重并体谅他人(respect others and be considerate). 培养独立性和克服困难(develop independence and overcome difficulties on their own). 但学生易受外界不良影响(bevulnerable to the negative influence in TV or on the Internet)，易模仿行为(tend to imitateparents" and teachers"behavior)，缺乏自控(lack self-control ability) 　　社会性发展：校园活动(campus activities)和社区服务(community service)可以帮助积累实践经验(accumulate practical experience to better adapt to society)， 培养沟通技能(communicationskill/interpersonal skills)，解决问题的能力(the ability to solve problems)，实习或兼职工作帮助了解工作环境(attend internships or take part-time job to better understand real workingenvironment)，认识朋友(make more friends， gain more personal resources) 　　雅思写作教育话题--三大影响源 　　家庭方面：父母对孩子的"性格养成起关键作用(play a key role in building the character);提供更丰富的经历(博物馆或旅游);更注重综合发展(overall development)。但很多孩子为独生子女(only child)，家长忙于工作(be busy with work)并且没有正确的教育方法(right parenting)可能会溺爱(spoil)或伤害孩子自尊(damage children"s self-esteem) 　　学校方面：主要教授知识，教师拥有专业的背景(professional knowledge)和丰富的经验(richexperience)，传授知识更有效(more effective in imparting knowledge)。对学生错误行为及时发现和处理(discover and deal with poor behaviors such as bully immediately)。校园活动和体育锻炼可以培养学生之间的合作竞争(competition & cooperation)，促使增强实践能力(improve practicalskills)，鼓励学生创新(encourage students to be creative)，激发好奇心和学习兴趣(inspirecuriosity) 　　社会方面：以消极方面居多，主要指媒体中出现的问题内容(questionable content)如暴力(violence)黄色(pornography)，青少年容易模仿(copy， imitate)，此外青少年不成熟(immature)未形成完整价值体系(value system)也容易被他人影响。 　　以上即为对雅思写作教育类题目的思路汇总和语料，我们若能把握这四大发展和三大影响源便可更加自信地应对不同的雅思写作题目。 　　[免责声明]本文来源于网络搜索整理，仅供学习交流使用。版权归原作者所有。 ;

六齿金线鱼。

Rent or Buy John and Linda have been arguing about whether to buy a house for a long time. They have been renting a small flat for several years, and the rent keeps going up. Last year, John wasn"t sure about his job situation , so they agreed to delay the decision. They also invested some money in the stock market , and their investments are doing well. Linda really wants to have a place of her own. She is growing impatient and doesn"t want to wait any longer. She wants to sell some of their investments and put the money into a nice house. They delayed their decision because John was uncertain about his job. She"s growing impatient and is tired of waiting. John is against buying now because he thinks prices are too high. He is also worried about the high cost of living in the area. This is beginning to make the area less attractive to companies. Unless a company is innovative and successful, it can"t afford to do business in the area. Salary levels have risen so quickly that companies can no longer afford to attract good workers. Good workers won"t come unless they are paid enough to buy a house. So many companies are relocating or moving overseas where costs are lower. They can"t afford to stay because of the high cost of living. It makes it more difficult for companies to stay. They invested some money in the stock market. John is worried that once companies start to leave, housing prices will come down. Only fools are buying now, paying prices that are probably 10 to 20% higher than they should be. He wants to buy when prices have fallen to a more reasonable level. Until then, it doesn"t make sense to buy. He thinks that companies will move out of the area, causing prices to weaken. If companies leave the area, people will lose their jobs and the demand for housing will decline. He remembers what happened in other countries just a few years ago, when prices climbed and then fell 15%. Many people lost their homes because they owed more on their homes than the homes were worth. When they lost their jobs, they couldn"t pay the mortgage. They couldn"t sell either, because the selling price was less than what they owed to the bank. So they had to move out and the banks took possession. Now prices are rising again so the same thing could happen again. A cycle of boom and bust which people tend to forget. Unless they can pay cash, they"ll need to get a loan from a bank to help pay for it. A cycle of boom and bust when an economy grows too fast, then takes a rapid fall, and the cycle begins again. Linda has a different view. She thinks he worries too much. She thinks if they buy now, prices will continue to rise. If they don"t buy now, they will miss the opportunity and regret it later. She isn"t worried by the possibility that the prices may drop in the future. She isn"t sure, but she thinks prices will continue to rise. She thinks they will regret it later if they don"t buy now.Another reason John is against buying a house is that he doesn"t have confidence in his new company. It is no longer growing as fast as it used to. Though the management talks about a bright future, he has doubts. They say great things to keep everyone motivated, but he doesn"t trust them. When he does a SWOT analysis of the company, he is even more concerned. SWOT is an acronym for Strengths, Weaknesses, Opportunities and Threats. The company"s strength is based on technology that is very competitive. But technology changes fast and what"s good now will soon be out of date. Continuous innovation is necessary. In the SWOT acronym, the O stands for opportunities. The company"s weakness is that it hasn"t developed an alternative to what it has now. Nobody is working on the next generation. There are already signs that their technology is nearing the end of its life cycle. There"re still opportunities if the company is willing to hire new people or acquire a company with new technology. The main threat is that other companies are spending more on research and development. The main threat facing the company is that its competitors are spending more on research and development. The company still has opportunities if it takes steps to acquire new technology. So based on his analysis, the company is okay for the next year or two. But beyond that, its future is questionable. As a result, John doesn"t want to buy a house now and take on a huge debt. Until he has more confidence in his situation, he doesn"t want to take the risk. If he would to buy a house now, it would mean taking on a huge debt . His wife thinks he"s too conservative. She has waited long enough and she doesn"t want to wait any longer. So John"s dilemma is how to balance his wife"s happiness against the risk of losing a lot of money. One thing for sure is that she isn"t happy as things stand now. She"s been waiting for a long time and he loves her. So the decision seems clear. John knows exactly what to do. Maybe some flowers and a celebration? What are they going to celebrate? The decision to buy a house. Based on his analysis, the company"s long-term future is questionable. He has to decide between his wife"s happiness and the risk of losing money. They are going to celebrate the decision to buy a house regardless of the risks. If you sell your home at a price less than what you paid for it, you"ll take a loss.

书中给的答案并没有错。“明知。。。还。。。有人。。。”等等是意译时为了句子结构的需要而添加上去的。原句的这部分如果直译的话，译文应该是“在关于失败的特定知识之中进行的竞争是肯定有害的”，我不同意楼下的说法，我觉得这句话说的其实很地道，表达的就是：知道“（总有人会）失败”是一种“知识”，你在明明有这些知识的情况下还要开展竞争，这肯定是有害的。英语中，对任何东西的知晓都可以用名词knowledge来表示，并不一定是科学的、正确的、成体系的知识。

Wi-Fi的长写是Wireless Fidelity，即802.11无线网络的代名词。 Wi-Fi自去年开始已成为资讯科技界的热门话题，其与3G的比较更掀起了u3192阵热烈的讨论。虽然暂时的结论是两者可以互相补足，但实际如何还看官拭目以待。 最近有生产商研发支援Wi-Fi的手提电话，利用VoIP的方法提供话音服务，着实对流动网络商造成冲击。有见及此，Nortel Neork亦为流动网络商发展u3192套融合流动网络及Wi-Fi的设备，流动网络商能在其已拥有的流动网络u3196，为客户提供安全的Wi-Fi热点(Hotspot)建接。 事实u3196，在欧洲，差不多所有大型流动网络商，包括T-Mobile、Orange、O2等等，都已经推出Wi-Fi服务。为什么流动网络会这么热衷投入Wi-Fi的怀抱？虽然他们都相信u3196述的「互相补足」论，但不能否定的是，Wi-Fi将会夺取了u3192部分3G数据收入，他们不能打败Wi-Fi，也不可否定他们的存在，自然便要参与这个游戏，以保障其市场份额和收入。其实此现象在u3197国、美国及亚洲亦己出现，奇怪的是中国香港的流动网络商似乎还未有所行动呢！ 有趣的是，加拿大的Bell Canada在2002年尾公布了u3192个计划，因应街边电话亭越来越少u319f使用，索性将他们变成Wi-Fi热点，提供Wi-Fi服务，不知中国香港的电讯盈科会否考虑。让我们看看u3192些数据及预测罢。直至2002年尾，在美国大慨有4 000个Wi-Fi热点，预计在未来u3194年至少有30 000个之多。 Wi-Fi *** ，自由的百科全书 Wi-Fi全名Wireless fidelity 是IEEE定义的一个无线网路通信的工业标准(IEEE 802.11)。 网路协议 编辑 应用层 DNS FTP TFTP ENRP，HTTP IMAP IRC NNTP POP3 RTP SIP SMTP SNMP SSH Tel BitTorrent DHCP ... 传输层 DCCP SCTP TCP UDP IL RUDP ... 网路层 IP(IPv4 IPv6) ICMP ARP RARP IGMP...
