展示范文之前，我有必要对综合写作对于托福写作的重要性先强调一下。很多老师也好学生也罢，会不自觉的把独立写作（字数要求300词以上）称为大作文；把综合写作（字数要求150-225词）称为小作文。这也给很多学生带来困惑，我问过很多学生，居然也有不少学生认为综合写作和独立写作的分值比例是1比2的关系。这点认识非常可怕；其实综合写作和独立写作的分值是完全相同的，不同之处主要在于考试形式，考试时间和字数要求等有所区别而已。

　　因此，想最终考出的托福写作成绩，重视综合写作是非常有必要的。而且，综合写作主要考查阅读信息和听力相关信息的提取和整合能力，考察点相对客观且容易把握。对于阅读和听力水平不错的孩子而言，他们取得综合写作的高分简直易如反掌。反之，学生则需要好好训练自己的阅读和听力水平了。接下来，我将以TPO17来展示综合写作范文给各位参考：

　　TPO17

　　Reading

　　In the past century, the steady growth of the human population and the corresponding increase in agriculture and pesticide use have caused much harm to wildlife in the United States,birds in particular. Unfortunately for birds, these trends are likely to continue, with the result that the number of birds in the United States will necessarily decline.

　　First, as human populations and settlements continue to expand, birds' natural habitats will continue to disappear. Forests, wetlands, and grasslands will give way to ever more homes, malls, and offices. As the traditional areas suitable for birds keep decreasing, so will the size of the bird populations that depend on those vanishing habitats.

　　Second, agricultural activities must increase to keep pace with the growing human population. The growth of agriculture will also result in the further destruction of bird habitats as more and more wilderness areas are converted to agricultural use. As a result, bird populations in rural areas will continue to decline.

　　Third, as human settlements expand and agriculture increases, the use of chemical pesticides will also increase. Pesticides are poisons designed to kill agricultural and home garden pests, such as insects, but inevitably, pesticides get into the water and into the food chain for birds where they can harm birds. Birds that eat the poisoned insects or drink contaminated water can die as a result, and even if pesticides do not kill birds outright, they can prevent them from reproducing successfully. So pesticides have significantly contributed to declines in bird population, and because there will continue to be a need to control agricultural pests in the future, this decline will continue.

　　Listening

　　The passage claims that there will be fewer and fewer birds, but the arguments used to support this claim are unconvincing.

　　First, it’s true that urban growth has been bad for some types of birds, but urban development actually provides better and larger habitats for other types, so much so that city and suburban dwellers often complain about increased birds populations,seagulls at landfills, pigeons on the streets and so on. Even birds like hawks and falcons can now be found in cities, where they prey on the increasing populations of pigeons and rodents. So it’s not going to be a story of uniform decline of bird populations in the future. Some populations may shrink, but others will grow.

　　As for agriculture, it’s true that it too will increase in the future, but not in the way assumed by the reading passage. The truth is, in the United States, less and less land is being used for agriculture every year. Increasing in agricultural production have resulted from and will continue to result from the introduction of new, more productive varieties of crops. These new crops produce more food per unit of land, and as a result, there’s no need to destroy wilderness areas.

　　And third, while it’s certainly true that traditional pesticides have been destructive to birds, it’s incorrect to project this history into the future. Now that people are aware of the possible consequences of traditional pesticides, two changes have occurred. First, new and much less toxic pesticides have been developed, and that’s important. Second, and perhaps more importantly there is a growing trend to develop more pest resistant crops, crops that are genetically designed to be unattractive to pests. Pest resistant crops greatly reduce the need for chemical pesticides. And best of all, pest resistant crops don’t harm birds at all.

　　上面分别是TPO17综合写作的阅读和听力部分，下面是综合写作的范文：

　　The passage states that the population of birds is decreasing. On the contrary, the lecture casts doubt on this. He thinks the number of some kinds of birds decreases while others increase.

　　First, the author mentions that because of the expansion of human population, the birds’ number is decreasing. Cities occupy bird habitats. However, the professor disagrees with this by saying that urban expansion provides better and larger habitats for birds. Sometimes even birds of prey like falcons come to cities preying for pigeons and rodents.

　　Second, the writer asserts that the development of agriculture along with the expanding population turns bird habitats to agriculture use. Birds have nowhere to live, and their population decreases. By contrast, the speaker refutes this and declares that the development of agriculture provides newer and more productive crops. There is enough food for humans, so there is no need to exploit more bird habitats. Thereby, there is no more harm to birds.

　　Last, the article announces that the use of chemical pesticide both kills the birds’ food and decreases the reproduction rate. Pesticide decreases the population of bird both directly and indirectly. Nevertheless, the listening rebuts this by saying that humans make two changes for birds. First, they use less toxic pesticide. Second, more pest-resistant crops are grown which have no harm to birds at all.

　　此篇托福综合写作满分范文的几个优点：，阅读信息的展示简洁且全面；第二，听力信息包含分论点的回应且附带细节；第三，全文的连接部分以及一些关键实词（如信息表达者的用法，关键动词用法）基本没有重复。
