很多收藏者想通过参加小组交流会和交换物品信息来拓展自己的杜交生活，这是参加桥牌俱乐部或健身房的一种变体形式，同样可以使他们接触到志趣相投的人群。

收藏的另一项动机是想要发现一些特别的事物，或所收藏物中一个特殊的样品，比如某位歌手罕见的早期唱片一些人可能会穷尽一生去寻找从心理学角度而言，这可以赋予他们生命的意义，否则他们就会感到漫无目的。

尽管如此，这也存在一种风险——如果他们足够幸运找到了所追寻的东西，他们不会去庆祝成功，反而会感到十分空虚，因为那种驱使自己前进的目标已然消失。

如果你想一想集邮，这一行为的另一项潜在原因或可能的结果是它的教育价值集邮打开了一扇窗户，让人们了解其他国家、植物、动物以及上面的名人.同样，仨19世纪，很多收藏家从全世界收集化石、动物和植物，他们的收藏品提供了关于自然界的大量信息倘若没有这J收藏品，找们对于内然界的了解将是远远F够的。

过去如今也是，只是程度稍弱猜火车是一种广受欢迎的收藏形式，尤其是在男性群体之间这主要是去看每种特定类型的火车机乍，借助公斤数据辨识每仲机车，并说出所见火车的名字，如今，爱好猜火车的人会互相交流信息，如今多是通过手机，这样他们可以确定去哪里可以看到一种特定的火车机车随之而来的是，很多爱好者非常了解铁路的运作，或是不同机车类型的技术规格。

Test 5（pp216-218）Part IV V ocabulary and Structure（以下试题是根据勘误表调整后的试题。

）Section A46. If only he _______ what I tell him, but he won’t.A. had doneB. would doC. would have doneD. has done解析：if only用以表示对现时或未来的愿望或者与过去事实相反的愿望，后接句子均要用虚拟语气。

所以答案为B. 47. Five minutes earlier, _______ we could have caught the last train.A. andB. orC. soD. but解析：Five minutes earlier是名词性独立结构，相当于隐含了一个非真实条件句（if we had arrived five minutes earlier）,这种结构后出现的句子要用逗号和and 连接。

48. A suitcase with shirt, trousers and shoes _______ stolen from the car.A. have beenB. hasC. wasD. are解析：此句主语是a suitcase, with shirt, trousers and shoes是后置定语，所以谓语要用第三人称单数。

49. They talked in whispers, but still, I couldn’t help but _______ their conversation.A. overhearB. to overhearC. overhearingD. overheard50. Her wish was that he _______ at Beijing University at once.A. studiesB. studiedC. studyD. will study解析：Her wish（她的愿望），从句要用虚拟语气（should+动词原型），should往往可以省略，故答案为C。

剑桥雅思12Test5雅思听力Section3答案+解析谈话场景，学习场最人物关系：两位学生Trudie和Stewart谈话话题：关于公共图书馆的论文section2解析，请点击：剑桥雅思12Test5雅思听力Section2答案+解析1、“Yes, but remember we're only supposed to write a short paper, so it's probably best if we don't gointefimdinginanydetaiL (是的，但别忘了我们只需要写一篇短论文，所以我们最好别写太多关于资金方面的细节。

)”广其中be supposed to do意为“应该做某事”;go into 意为“研究，探究”。

2、“But the digitalised books thai are available online free are mostly out of copyright, aren't they? And copyright in this country lasts for 70 years after the author dies. So you won’t find tbe latest best-seller or up-to-date information.(但是绝大部分网上免费提供的电子书都是版权失效的书，不是吗?在这个国家一个作者对其作品的版权会在他死后70年才0，所以你在电子书库里找不到最新的一?畅销书或者嵌新信息。

r其中out of copyright 是指作者死后70年.他对这本书的版权失效,所以图书馆就可以提供该书的免费电子版给读者。

3、“I'd like to think so, and that they'll still be serving their traditional ftmcdon，but I’m not so sure.There are financial implications, after all.(我想佐足这样，书馆外:未来还是会履行它们传统的功能，但我也不确定，毕竟这涉及财务经费问题。

一、雅思作文求评分,谢谢啦我觉得你写的不错，结构很清晰，论点和论据一目了然。

长短句结合。

也有例子具体的分数我不好评，因为我的作文也就考了6.5.我就说说我认为的不足的地方吧，希望能帮到你。

第一是按照你的观点，你认为先工作旅游是好的，那么主体写的时候最好先写你不同意的观点。

也就是把你这两个主体段换一下位置。

第二是如果你想拿高分，最好能用上一些好词来代替比较普通和简单的表述。

第三是我觉得最后的conclusion说这样可能会让年轻人找到一些方向这个观点应该是一个新的观点吧？你的支持段里并没有说到这个好处。

而结论段式不允许出现新的观点的，应该是总结你的陈述。

如果你想加上这个支持观点可以写进主体段里。

然后综上所示，虽然先工作旅游有一些缺点，但是它既可以增长知识，又可以帮助青少年更好的实现目标。

所以你支持先工作旅游这一观点。

总体来看六分以上是绝对没问题的，如果结合你小作文也不错的话，六点五的可能比较大，当然没准儿对哪个考官的胃口七分也不是没有可能的。

二、雅思剑5test1小作文求评价The line graph describes some data about the percentage =》是不是可以改成 The line graph describes the percentage。

aged 65 and over =》aged 65 and older ?As can be seen from this line graph,there is an increasing trend in the number of old people in three countries.More precisely,the percentage of population went up gradually from 9% in 1940 to 15%in 1982 and it will remain stable at 14% in 2018（那个国家？）.After that（去掉？），the proportion of population aged 65 and over is expected to reach 23% in 2040.Similarly（跟什么说similarly，前后说的好像不一样），the proportion of population age 65and over in Sweden accounted for 7% in 1940 to 26% in 2040（对将来数据的预测，时态是否不对？）.While,the percentage of population aged 65 and over in USA remained steady at 5% by the end of 2008,After that, there is a substantial surge and occupies at 27% in 2040（对将来数据的预测，时态是否不对？）.Therefore,it shows that the percentage of 65+ people are soring moderatelyin the next three decades.（未来三年应该是数据预测，不是shows吧。
