托?？谡Z(yǔ)task4分析

托福口語(yǔ)task4分析，相信這個(gè)問(wèn)題是許多正在準(zhǔn)備留學(xué)的同學(xué)關(guān)心的一個(gè)問(wèn)題，那么下面小編就來(lái)和大家說(shuō)一說(shuō)，感興趣的您趕緊往下了解吧。

托福口語(yǔ)task4閱讀內(nèi)容：

? Carrying Capacity 00:45 seconds

? 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. ? The greatest number a habitat can support is known as the carrying capacity. ? 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.

記Title:

由于task 4的閱讀主要是關(guān)于某一個(gè)科學(xué)術(shù)語(yǔ)的解釋和說(shuō)明，考生在開(kāi)始閱讀的第一秒鐘就應(yīng)該迅速在紙上紀(jì)錄下閱讀的題目——即科學(xué)術(shù)語(yǔ)本身。

記定義:

常見(jiàn)的表示定義的提示詞有 refer to, known as, is, is called, etc.

注意點(diǎn):

若定義過(guò)長(zhǎng)或者很難確定的時(shí)候，考生應(yīng)當(dāng)舍棄該定義,但必須說(shuō)出閱讀文章中的title.

Task 4中的定義句不一定出現(xiàn)在段首，也非?？赡艹霈F(xiàn)在段尾或者段中。

Title:

Carrying Capacity

考生對(duì)Carrying一詞較熟，可預(yù)測(cè)段落解釋重點(diǎn)放在Capacity上。

定義:

?中重復(fù)出現(xiàn)了標(biāo)題Carrying Capacity，并且有非常明顯的提示詞known as 。結(jié)合內(nèi)容，承載能力是指棲息地上所能承載最大的數(shù)量。因此，該句是定義句。

注意點(diǎn):

很多考生認(rèn)為定義句一般出現(xiàn)在段落開(kāi)頭，但?中指出，動(dòng)物需要足夠的食物和水的資源，但是由于資源有限，就只能允許特定數(shù)量的物種在一個(gè)特定的地方生存，不是定義句。

?中是對(duì)carrying capacity的具體描述，因?yàn)榫渥虞^長(zhǎng)，考生應(yīng)該對(duì)內(nèi)容加以概括或適當(dāng)舍棄。

托?？谡Z(yǔ)task4聽(tīng)力內(nèi)容：

OK, ? so let’s talk about what happened to a certain type of insect, a moth, a red-and-black moth that lives in Europe. ? 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. ? 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.

1 Example:

? 中教授以red-and-black moth 來(lái)講授Carrying Capacity的概念。

? 中，教授說(shuō)道，red-and-black moth 以Ragwort為食，而體表蛾生存的地方有很多的Ragwort，因此就有許多的蛾子生活在這片區(qū)域，結(jié)果是這些蛾子的總數(shù)量是保持相對(duì)穩(wěn)定的狀態(tài)。?中，教授講到，有一年有特殊情況出現(xiàn)，雨水比平時(shí)少很多，結(jié)果導(dǎo)致Ragwort生長(zhǎng)情況不好，因而蛾子就沒(méi)有足夠的食物來(lái)源，很多沒(méi)能生存下來(lái)。過(guò)了一年，雨水恢復(fù)正常，有足夠的Ragwort plants生長(zhǎng)起來(lái)，又為蛾子提供了食物來(lái)源，結(jié)果是蛾子的數(shù)量增加了。

教授用雨水對(duì)Ragwort的影響，進(jìn)一步影響到蛾子食物來(lái)源而導(dǎo)致數(shù)量的增減來(lái)說(shuō)明環(huán)境承載能力的變化。

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.

In the reading, the article talks about___?___, (which means___?___)

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

For instance, ___________?____________.

The second is___________?____________.

Therefore, by giving out this/these example(s), the professor tells us the meaning of ______?______.(optional)

托?？谡Z(yǔ)task4解釋?zhuān)?/p>

根據(jù)拿到閱讀材料，立刻記下標(biāo)題的原則，?中說(shuō)出具體title，之后根據(jù)提示詞找出定義句，?中具體說(shuō)出definition。如果定義太長(zhǎng)或難以概括，可以省略不說(shuō)。

聽(tīng)講座時(shí)，帶著“老師用什么例子來(lái)進(jìn)行說(shuō)明”這個(gè)問(wèn)題去聽(tīng)。聽(tīng)力材料的前兩句話，老師會(huì)給出所聽(tīng)內(nèi)容的概括性介紹。再結(jié)合閱讀給出的概念。再聽(tīng)舉例說(shuō)明。其方法通常是舉出擴(kuò)展事例，舉反例或是短文中概念的實(shí)際應(yīng)用。

?和?處分別復(fù)述講座中教授是如何用一個(gè)或者兩個(gè)例子，具體說(shuō)明閱讀材料中的academic topic的。

最后，如果時(shí)間有多余，可以加上結(jié)尾句，在?處重新說(shuō)出閱讀標(biāo)題，概括整個(gè)回答。

托?？谡Z(yǔ)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.
