托福口语Task4分析

托福口语task4阅读内容：

❶ Carrying Capacity 00:45 seconds

❷ An animal species needs to have enough resources, like food and water, to survive in any given environment. However, because resources are limited, only a certain number of animals of a particular species are able to survive in a given habitat. ❸ The greatest number a habitat can support is known as the carrying capacity. ❹ If nothing happens to disrupt or unbalance the relationship between the animal and its habitat, the carrying capacity will remain stable. However, a carrying capacity is not fixed. If there is a significant disruption, such as an environmental event that alters the amount of available resources in the habitat, the carrying capacity will change.

托福口语task4关键点

记Title:

由于task 4的阅读主要是关于某一个科学术语的解释和说明，考生在开始阅读的第一秒钟就应该迅速在纸上纪录下阅读的题目——即科学术语本身。

记定义:

常见的表示定义的提示词有 refer to, known as, is, is called, etc.

注意点:

若定义过长或者很难确定的时候，考生应当舍弃该定义,但必须说出阅读文章中的title.

Task 4中的定义句不一定出现在段首，也非常可能出现在段尾或者段中。

托福口语task4文本分析

Title:

Carrying Capacity

考生对Carrying一词较熟，可预测段落解释重点放在Capacity上。

定义:

❸中重复出现了标题Carrying Capacity，并且有非常明显的提示词known as 。结合内容，承载能力是指栖息地上所能承载最大的数量。因此，该句是定义句。

注意点:

很多考生认为定义句一般出现在段落开头，但❷中指出，动物需要足够的食物和水的资源，但是由于资源有限，就只能允许特定数量的物种在一个特定的地方生存，不是定义句。

❹中是对carrying capacity的具体描述，因为句子较长，考生应该对内容加以概括或适当舍弃。

笔记

Title:

Carrying Capacity

定义:

Greatest NO.

托福口语task4答题要点：

Definition:

The greatest number of animals a habitat can support is called carrying capacity.

托福口语task4听力内容：

OK, ❶ so let’s talk about what happened to a certain type of insect, a moth, a red-and-black moth that lives in Europe. ❷ These moths eat a plant called Ragwort and they live in fields where the Ragwort plants grow. Now, there was a group of moth that lives in one of these fields and, for many years, there was a lot of Ragwort growing there. So the moth had plenty to eat and the total number of moth in the field stayed pretty much the same. ❸ But then one year it rained a lot less than usual and the Ragwort didn’t grow as well.

The result was that the moth didn’t get enough to eat and many didn’t survive but even the ones that did survive didn’t lay as many eggs as before. So that year the moth population in the field was quite a bit smaller. The next year, though, the amount of rainfall returned to normal and again many more Ragwort plants grew and, once again, there was a lot available for the moth to eat. So that year the moth population increased and the female moth laid many more eggs than the year before. And now, after all that rainfall and plant growth, there were just as many moth in the Ragwort field as there were before.

托福口语task4关键点

1 Example :

教授在讲座中会用一个例子阐述阅读材料中的学术话题。在这种情况下，考生在复述过程中，应该尽可能地讲出该例子中的细节，并注意细节与细节之间的逻辑关系。

2 Examples:

或者，教授会在讲座中用两个例子阐述阅读材料中的学术话题，两个例子可能是有关于教授自身的经历，也有可能是来自其他方面。

托福口语task4注意点:

如果讲座中，教授讲述的是一个实验或者一项研究，考生务必从实验对象、实验过程、实验结果三个方面去论述阅读中的academic topic.

托福口语task4文本分析

1 Example:

❶ 中教授以red-and-black moth 来讲授Carrying Capacity的概念。

❷ 中，教授说道，red-and-black moth 以Ragwort为食，而体表蛾生存的地方有很多的Ragwort，因此就有许多的蛾子生活在这片区域，结果是这些蛾子的总数量是保持相对稳定的状态。❸中，教授讲到，有一年有特殊情况出现，雨水比平时少很多，结果导致Ragwort生长情况不好，因而蛾子就没有足够的食物来源，很多没能生存下来。过了一年，雨水恢复正常，有足够的Ragwort plants生长起来，又为蛾子提供了食物来源，结果是蛾子的数量增加了。

教授用雨水对Ragwort的影响，进一步影响到蛾子食物来源而导致数量的增减来说明环境承载能力的变化。

笔记

1 Example:

a moth, eat Ragwort, 数量稳定

Rain less，Rag. ×, M× survive

Rain normal, moth ↗

托福口语task4答题要点：

1 Example :

Moth is a kind of insect that eats ragwort. Ragwort is a plant that grows in the field. Normally, the number of moth in the ragwort field is stable. But if there were a lot less rain in a year, ragwort wouldn’t grow well. Moth wouldn’t survive and even those that survived lay fewer eggs. So the number of moth would decrease. But if the rain went back to a normal level, the ragwort would grow well.

托福口语task4答题模板：

In the reading, the article talks about___❶___, 【which means___❷___】

In the listening, the professor gives out one/ two example【s】 to explain the title.

For instance, ___________❸____________.

The second is___________❹____________.

Therefore, by giving out this/these example【s】, the professor tells us the meaning of ______❺______.【optional】

托福口语task4解释：

根据拿到阅读材料，立刻记下标题的原则，❶中说出具体title，之后根据提示词找出定义句，❷中具体说出definition。如果定义太长或难以概括，可以省略不说。

听讲座时，带着“老师用什么例子来进行说明”这个问题去听。听力材料的前两句话，老师会给出所听内容的概括性介绍。再结合阅读给出的概念。再听举例说明。其方法通常是举出扩展事例，举反例或是短文中概念的实际应用。

❸和❹处分别复述讲座中教授是如何用一个或者两个例子，具体说明阅读材料中的academic topic的。

最后，如果时间有多余，可以加上结尾句，在❺处重新说出阅读标题，概括整个回答。

托福口语task4范文：

In the reading, it says that the greatest number of animals a habitat can support is called carrying capacity. Carrying capacity is not fixed. It changes according to the environment. The professor uses the relationship of moth and ragwort to illustrate this concept. Moth is a kind of insect that eats ragwort. Ragwort is a plant that grows in the field. Normally, the number of moth in the ragwort field is stable. But if there were a lot less rain in a year, ragwort wouldn’t grow well. Moth wouldn’t survive and even those that survived lay fewer eggs. So the number of moth would decrease. But if the rain went back to a normal level, the ragwort would grow well. Moth would have enough to eat and would lay more eggs. And the number of moth would also increase.
