摘要:常州朗阁7月16日雅思阅读考题回顾

  P1 学校中的艺术选修课

  P2 树冠的研究

  P3 移民的消费偏好

  朗阁讲师点评

  1. 本场考试的难度偏上。三篇文章相对都较难,其中第二篇文章是机经旧题,其他两篇都是新题。

  2. 整体分析:艺术相关(P1)、植物环境类(P2)、商业社科类(P3)。

  **篇文章暂时题型缺失,据学生的反馈难度较大,艺术相关的话题文章确实感观上较难。

  第二篇文章是之前考过的旧题,题型搭配是:段落信息匹配+填空+人名匹配。文章整体难度较大,还考到了***难的段落信息匹配,所以相对来说整体还是比较难的。努力从填空和人名匹配题里抓分。

  第三篇文章暂时题型缺失,据学生的反馈难度较大。

  Passage 1:学校中的艺术选修课

  题型:缺失

  具体文章待确认

  Passage 2:树冠的研究

  题型:段落信息匹配(5题)+填空(4题)+人名匹配(5题)

  参考文章:

  A The forest canopy-the term given to the aggregated crowns of trees in a forest-is thought to host up to 40 per cent of all species, of which ten per cent could be unique to the forest roof. "We're dealing with the richest, least known, most threatened habitat on Earth," says Andrew Mitchell, the executive director of the Global Canopy Programme/ a collection of groups undertaking research into this lofty world. "The problem with our understanding of forests is that nearly all the information we have has been gleaned from just two meters above the soil, and yet we're dealing with trees that grow to heights of 60 meters, or in the case of the tallest redwood 112 meters. It's like doctors trying to treat humans by only looking at their feet."

  B Tropical rainforest comprises the richest of ecosystems, rivalled only by coral reel for its diversity and complex interrelationships. And a great deal of that diversity lives up in the canopy-an estimated 70-90 per cent of life in the rainforest exists in the trees; one in ten of all vascular plants are canopy dwellers; and about 20-25 per cent of all invertebrates are thought to be unique to the canopy.

  C The first Briton to actually get into the canopy may have been Sir Francis Drake who, in 1573, gained his first glimpse of the Pacific Ocean from a tall tree in Darien, Panama. However, the first serious effort to reach and study the canopy didn't begin until 1929. The Oxford University Expedition to British Guiana, led by Major RWG Hingston, still ended up help of locals when it came to building an observation platform. It was a successful expedition all the same, despite the colony's acting governor getting stuck high up on a winched seat during a visit. In terms of canopy access, the French have proved themselves to be excellent innovators, taking things further with the development of 'lighter-than-air platforms -balloons and related equipment, to you and me. Francis Halle; from the Laboratoire de Botanique Tropicale at Montpellier University took to a balloon in the mid-1980s in order to approach the canopy from above. His work in French Guiana was inspired by the use in Gabon of a tethered helium balloon by Marcel and Annette Hladick. Halle went one further by using a small purpose-built airship-a cigar-shaped balloon with propellers to aid manoeuvrability. "We suddenly had a mobile system that could move around the treetops; there was no other means of doing this," says Mitchell.

  D From this, two balloon-dependent features have developed: the radeau or raft, and the luge or sledge. The raft is a 'floating' platform, employed by French academics Dany Cleyet-Marrel and Laurent Pyot and is essentially an island in the treetops. Made of kevlar mesh netting and edged with inflated neoprene tubes, it rests on top of the canopy, allowing sampling (mostly of plants and insects) to take place at the edges of the platform, and can stay in position for several days. The luge, on the other hand, is an inflated hexagon similar to a traditional balloon basket but with a hole in the bottom covered with Kevlar mesh. Such techniques aren't without their problems, however, "balloons can cover larger areas, especially for collection purposes, but they are extremely expensive- Jibe raft alone cost 122,000 [euro] (86,000 [pounds sterling]) in 2001], nut very effective because you can only reach the tops of the trees, and are highly dependent on the weather, " says Dr Wilfried Morawetz, director of systematic botany at the University of Leipzig. “Balloons can usually only be used in the early morning for two to four hours. Last time, we could only fly three times during a whole week." Given these factors, it comes as no surprise that operations involving these balloons numbered just six between 1986 and 2001.

  E Smithsonian Tropical Research Institute in Panama. Smith had the idea of using a static crane to get into the treetops. Un-tethered balloons may allow widely distributed sites to be sampled, but cranes allow scientists to study an area of at least a hectare from soil to canopy throughout the year, year after year. "Cranes beat any other access mode. They are cheap, reliable and fast. In two minutes I can reach any point in our forest, which is essential for comparative measurements across species," says Professor Christian Korner of the University of Basel. Korner is using a static crane in a unique carbon dioxide-enrichment experiment in Switzerland, in an attempt to discover how forests might respond to the global increase in atmospheric carbon dioxide (see Swiss canopy-crane carbon experiment, right). For reasons of convenience, cranes are generally situated close to cities or a research center. Leipzig University has a crane not far from the town, the Location allowing scientists to study the effect of city pollutants on forests. In order to increase the amount of canopy a crane can access, some have been mounted on short rail tracks. In "1995, Dr Wilfried Morawetz was the first to use this technique, installing a crane on 150 meters of track in Venezuelan rainforest. “In my opinion, cranes should be the core of canopy research in the future," he says.

  F It appears that the rest of the scientific community has now come around to Mitchell's way of thinking. "I think most scientists thought him mad to consider such a complex field station at first," says internationally respected 'canopist' Meg Lowman, the executive director of the Marie Selby Botanical Gardens. "However, we've all come to realize that a combination of methods, a long-term approach to ecological studies and a collaborative approach are the absolute best ways to advance canopy science. A permanent canopy field station would allow that to happen." With A dedicated group of canopy scientists working together and a wide range of tools available for them to get into the treetops, we're now finally on our way towards a true understanding of the least-known terrestrial habitat.
