PASSAGE 2
A I have recently planted a hedge. Living in a rural environment, I made the decision to plant only native species, including field maple, hawthorn, hazel, dog-rose and blackthorn. In time this will grow to form a dense hedge whose primary purpose is to form a windbreak, but which will also be attractive both to me and to wildlife. In the two years since planting, a number of hedgerow wild flowers, such as scabious and knapweed have already begun to colonize the spaces between the growing shrubs. Of course, if allowed to grow too freely, rank weeds and grasses will limit the growth of the hedge and need to be removed. This is done by hand, without the use of herbicides, in order to encourage bio-diversity.

B But it is not only native species that have found a foothold in the new growing environment. A number of garden plants of non-native origin have also established themselves. Some have come via wind-blown seeds, some through bird droppings, while others have arrived through human agency, stuck to the soles of boots or as dormant seeds embedded in garden compost. They include Lychnis coronaria, Echinops ritro and Brunnera macrophylla, all valued garden plants, but looking rather out of place in a natural setting. Such intruders are called ‘garden escapes’, and it isn’t only my garden they are escaping from.

C In his recently published book, Flora Britannica (1998), Richard Mabey devotes a whole chapter to garden escapes. Many of these are relatively recent introductions, such as the Indian balsam which was first brought to Britain from the Himalayas in 1829, and Fuchsia magellanica which arrived about the same time. Both of these grow wild in Britain now; Indian balsam may be found along riversides and in damp places all over Britain, while Fuchsia magellanica is mostly confined to mild south-west England. Buddleja davidii was introduced from its native China in the 1890s and is now a ubiquitous shrubby weed of urban wasteland, derelict building sites or crumbling walls. Its dusky purple flowers are much frequented by butterflies and for this reason it is by no means an unwelcome interloper. Like the others it has succeeded by exploiting an ecological niche. No native British plant species has been able to colonize dry inhospitable urban landscapes to such advantage.

D Other vigorous aliens introduced as garden plants are now regarded as pernicious weeds. One such is Japanese knotweed, probably introduced into Victorian gardens in the 1840s. Its root system extends rapidly and it is able to regenerate from the smallest fragment of root. It forms dense thickets reaching 1.5 metres。。。。。。。。。。字数超限，这能附上这么多，求高人解答！！

在雅思阅读的学习过程中，学生经常问到，“剑一至剑六都做了好几遍了，文章都非常熟了，还有其他的阅读材料可以使用吗？应该读什么样的材料呢？”针对这个问题，我带领大家探究一下A类雅思阅读文章的来源，并为大家提供一些推荐的阅读材料。

　　首先，细心的同学已经发现从剑四开始每本书的后面都多了一个acknowledgements。其实在acknowledgements里面已经给出了剑桥这几本材料里面阅读文章的来源。经过总结归纳不难发现，雅思A类文章主要来自于学术出版物，而非一般娱乐性出版物。其中主要用到的学术杂志如下：

　　1.New Scientist 这本杂志被用到的频率最高，如剑四中的Lost for Words, Play is a Serious Business，剑五中的What’s So Funny?, Flawed Beauty: the Problem with Toughened Glass，和剑六中的多篇文章 Australia’s Sporting Success, Climate Change and the Inuit, Graying Population Stays in the Pink, Do Literate Women Make Better Mothers?

　　2.The Economist 列居其次，如剑五中的The Truth about the Environment, 剑六中的Delivering the Goods

　　3.还有American Scientist和Scientific American这两个主要的美国学术期刊，例如剑五的Disappearing Delta和剑六的The Search for Anti-aging Pills

　　4.当然还有National Geographic。但是值得注意的是，因为这是休闲杂志，所以只作为了G类的阅读，如剑六中的Pterosaurs

　　除了以上提到的若干来源之外，雅思A类的阅读文章还出自Nature, Discover, Time (Europe), Boston Global, History Today等其余期刊或杂志。至于是哪次考试的哪篇文章，由于敏感原因在这里就不在透露。

　　了解这些雅思文章出处之后对于广大考生平时进行泛读训练具有很好的指导作用。考生甚至可以使用阅读机经，从以上杂志期:刊的官方网站上搜索到相关背景文章进行有针对性的阅读训练。

　　特别说明：由于各方面情况的变化与调整，新东方雅思网所提供的所有考试信息仅供参考，敬请考生以权威部门公布的正式信息为准。

我先给你翻译过来了
A最近，我种了对冲。在农村居住环境，我决定只种植本地物种，包括实地枫树，山楂，榛子，狗玫瑰和黑刺李。随着时间的推移这将增长到形成一个密集的对冲，其主要目的是要形成防风，但同时也将吸引到我和野生动物。在两年来种植，绿篱的野花，如scabious和knapweed，数量已经开始殖民之间日益增长的灌木的空间。当然，如果允许增长过自由，排名杂草和草将限制对冲增长，需要拆除。这是手工完成的，没有使用除草剂，以鼓励生物多样性
B但它不仅找到了新的生长环境，在立足本地物种。一个非本地的园艺植物，原产地也建立了自己。有些人来经风吹种子，有的通过鸟粪，而另一些已经抵达通过人力机构，坚持靴子或在庭院堆肥嵌入式休眠种子的鞋底。它们包括Lychnis冠状，Echinops ritro和Brunnera艽，所有有价值的园林植物，但看着外面的地方，而在自然环境中。这些入侵者被称为“花园逃脱”了，它不仅是我的花园，他们是逃离
在他最近出版的书，植物全书（1998）C，理查德玛贝专门用一整章来花园逃逸。其中许多是相对较新的引进，如印度苦瓜这是第一次带来了从喜马拉雅山到英国在1829年，和紫红色magellanica约在同一时间到达。这两种横生现在在英国，印度苦瓜可发现沿河畔，在遍布英国潮湿的地方，而紫红magellanica大多局限于温和英格兰西南部。醉鱼草刺是引进原生中国在19世纪90年代，现在是无处不在的城市灌木杂草的荒地，废弃的建筑工地或摇摇欲坠的墙壁。它的暗紫色的花蝴蝶和经常光顾的多为这个原因，它决不是一个不受欢迎的闯入者的。像其他人已经成功地通过利用生态利基。没有英国本土植物物种已经能够殖民干燥荒凉的城市景观等优势。

D其他的园林植物引入大力外国人现在被视为有害杂草。其中一个是日本蓼，大概到维多利亚花园介绍，在19世纪40年代。它的根系迅速扩展，并能再生的根最小的片段。它形成密密麻麻达到1.5米。。。。。。。。。。
