托福综合写作生态学考点分析
生态题材一向是托福考试中经常出现的考点，同学们可以花费一些心思了解一下。那么下面就和我爱学习网的小编来看看托福综合写作生态学考点分析。
备考托福综合写作最重要也是最有效的资料就是TPO，我们可以好好把握TPO中曾经考察过的相关内容，挖掘重要考点与信息。具体来看，TPO14、TPO18、TPO20的这三篇主要考察要点都和环境保护息息相关：
（阅读论点--- 听力论点）
TPO 14：回收性砍伐的好处
1. make room for the growth of the new trees---deprive the soil of the nutrients produced during the process of decomposition
2. minimize the danger of insect infestation---some insects are great contributors to the health of the forest
3. provide usable wood by industries and create additional jobs for local people---transportation of these woods is expensive and the jobs provided are temporary
TPO 18：佛罗里达榧树减少的解决方案
tablish Torreya in the same location
with the coolest and dampest microclimate---the microclimate is strongly influenced by either global warming or the drained wetlands
Torreya to an entirely different location---Torreya will threaten other rendangered species
erve Torreya in research center---the research center can not ensure a large and genetically-diverse population of the Torreyatrees， which means the trees are not capableof resisting the disease
TPO 20：Let it burn policy 带来的危害
1. damage the trees as well as the vegetation---there appears to be a biggerdiversity for the plants
g negative effects to the wildlife---small animals like the rabbits and hares are more likely to inhabit in the ideal place
harm to the local tourism， negatively contributing to the economy---only if it happens every year would it be a problem for tourism
从单词的层面上看，生态学相关的托福综合写作部分我们主要需要做好以下几方面词汇积累：
物种名称词汇（ 植物）：plant / cedar / plankton / Terroya tree / wild berry / organism / black locust tree
物种名称词汇（动物）：wildlife / insect / beetle / bear / mussel / hare / rabbit / shellfish
涉及栖息地词汇：habitat / dwell / inhabit / habitat / bottom / wetland
生物链涉及词汇：food chain / plankton eater/ predator / parasite / disease / infestation / infest / pest-resistant / resist / dominate / reproduce / germinate / nutrient
关于物种入侵：wipe out / crowd out / be aggressive / invade / invasion / colonize / compete for
表示物种数量的下降：decline / descend / shrink / extinct / endangered / minimize / devastate / destroy
科学技术层面的单词：genetic modification / genetictechnology / genetically –diverse / geneticallymodified / uniform / gene / pesticide
在托福综合写作的阅读和听力材料中，常常会出现的生态学相关考点包括：生物减少原因、生物保护方法、防止生物扩散的方法。
生物减少原因：
Environment： temperature / climate change / global warming
Technology： genetically-modified plants /pest-unresistant / uniform in genes
Invasion： compete for nutrient/ infestation / parasite / predator
生物保护方法：
Environment： temperature / climate change / relocation
Technology： research center
防止生物扩散的方法：
Biological introduction： predator
Human activities： capture （financially beneficial） / chemical control （poison / pesticide）
