剑桥雅思4阅读文章分析：热带雨林

　　Adults and children are frequently confronted with statements about the alarming rate of loss of tropical rainforests. For example, one graphic illustration to which children might readily relate is the estimate that rainforests are being destroyed at a rate equivalent to one thousand football fields every forty minutes-about the duration of a normal classroom period. In the face of the frequent and often vivid media coverage, it is likely that children will have formed ideas about rainforests-what and where they are, why they are important, what endangers them-independent of any formal tuition. It is also possible that some of these ideas will be mistaken .

　　固本文主题或问题就是儿童关于热带雨林看法的对错

　　Many studies have shown that children harbour misconceptions about pure, curriculum science. These misconceptions do not remain isolated but become incorporated into a multifaceted, but organized, conceptual framework, making it and the component ideas, some of which are erroneous, more robust but also accessible to modification. These ideas may be developed by children absorbing ideas through the popular media. Sometimes this information may be erroneous. It seems schools may not be providing an opportunity for children to re-express their ideas and so have them tested and refined by teachers and their peers.

　　Despite the extensive coverage in the popular media of the destruction of rainforests, little formal information is available about childrens ideas in this area. The aim of the present study is to start to provide such information, to help teachers design their educational strategies to build upon correct ideas and to displace misconceptions and to plan programmes in environmental studies in their schools.

　　第三段调查研究开始。调查过程

　　The study surveys childrens scientific knowledge and attitudes to rainforests. Secondary school children were asked to complete a questionnaire containing five open-form questions. The most frequent responses to the first question were descriptions which are self-evident from the term rainforest. Some children described them as damp, wet or hot. The second question concerned the geographical location of rainforests. The commonest responses were continent or countries: Africa , South America, Brazil. Some children also gave more general locations, such as being near the Equator.

　　Responses to question three concerned the importance of rainforests. The dominant idea, raised by 64% of the pupils ， was that rainforests provide animals with habitats. Fewer students responded that rainforests provide plant habitats, and even fewer mentioned the indigenous populations of rainforests. More girls and boys raised the idea of rainforest as animal habitats.

　　Similarly, but at a lower level, more girls than boys said that rainforests provided human habitats. These observations are generally consistent with our previous studies of pupils views about the use and conservation of rainforests, in which girls were shown to be more sympathetic to animals and expressed views which seem to place an intrinsic value on non-human animal life.

　　The fourth question concerned the causes of the destruction of rainforests. Perhaps encouragingly, more than half of the pupils identified that it is human activities which are destroying rainforests, some personalizing the responsibility by the use of terms such as we are. About 18% of the pupils referred specifically to logging activity.

　　One misconception, expressed by some 10% of the pupils, was that acid rain is responsible for rainforest destruction; a similar proportion said that pollution is destroying rainforests. Here, children are confusing rainforest destruction with damage to the forests of Western Europe by these factors. While two fifths of the students provided the information that the rainforests provide oxygen, in some cases this response also embraced the misconception that rainforest destruction would reduce atmospheric oxygen, making the atmosphere incompatible with human life on Earth.

　　In answer to the final question about the importance of rainforest conservation, the majority of children simply said that we need rainforests to survive. Only a few of the pupils mentioned that rainforest destruction may contribute to global warming. This is surprising considering the high level of media coverage on this issue. Some children expressed the idea that the conservation of rainforests is not important.

　　分析综合结果：

　　The results of this study suggest that certain ideas predominate in the thinking of children about rainforests. Pupils responses indicate some misconception in basic scientific knowledge of rainforests ecosystems such as their ideas about rainforests as habitats for animals, plants and humans and the relationship between climatic change and destruction of rainforests.

　　Pupils did not volunteer ideas that suggestedthat they appreciated the complexity of causes of rainforest destruction. In other words, they gave no indication of an appreciation of either the range of ways in which rainforests are important or the complex social, economic and political factors which drive the activities which are destroying the rainforests. One encouragement is that the results of similar studies about other environmental issues suggest that older children seem to acquire the ability to appreciate value and evaluate conflicting views. Environmental education offers an arena in which these skills can be developed, which is essential for these children as future decision-makers.
