      托福聽力30天備考計劃第十五天:環(huán)境科學(xué)的演講

        今天我們分析TPO 17【TPO17聽力文本(Conversation+Lecture)】中這篇環(huán)境科學(xué)的演講,通過這篇強(qiáng)調(diào)幾個細(xì)節(jié)題的考點(diǎn)。這篇文章除了第一題主旨題,最后一題重聽題以外,其余四題都是細(xì)節(jié)題。除了要了解細(xì)節(jié)題的,更重要的是能夠聽出相應(yīng)考點(diǎn)的信號詞。

        13.Why does the professor compare Earth's movements to a watch?

        Okay, a lot of people think of earth’s orbit around the sun as being perfectly circular, as smooth and as regular as um, say, the way the hands move on a, ona well-made watch. But, it just doesn’t work that way.

        這個題涉及到兩個細(xì)節(jié)題考點(diǎn):舉例和轉(zhuǎn)折。舉例的信號詞還是容易被忽略的“say". 舉例需要了解的是例子的大概內(nèi)容,舉例的目的以及相對應(yīng)的觀點(diǎn)。

        14.Why does the professor mention Northern Hemisphere glaciers?

        And when earth’s orbit is more elliptical, earth is actually closer to the sunduring part of the year, which makes earth, and in particular, the northern hemisphere warmer. And why is that important? Well, because most of the planet glaciers are in the northern hemisphere. And if it gets too warm, then glaciers will stop forming. And we already talked about how that affects earth’s overall temperature.

        這道題同樣可以說有兩個細(xì)節(jié)題考點(diǎn):問答和因果。問答考點(diǎn)分為兩種:教授自問自答以及教授學(xué)生互問互答。

        15.What is the significance of the evidence found on the ocean floor?

        Nowwhen Milankovitch first proposed this theory in the 1920s, many of his colleagues were skeptical, Milankovitch didn’t have any proof. Actually, there wouldn’t be any evidence to support his hypothesis until the 1970s, when oceanographers were able to drill deep into the seafloor and collect samples, samples which were then analyzed by geologist.

        非常明顯的轉(zhuǎn)折考點(diǎn),需要注意的是actually是作為轉(zhuǎn)折信號詞出現(xiàn)的。

        16.What did calcite deposits from Devils Hole reveal?

        Well,the “devil’s hole” findings contradicted the ones obtained during the 1970s, so basically the question was: were the ages of one, or both of the samples wrong?

        強(qiáng)調(diào)考點(diǎn),強(qiáng)調(diào)分兩種:語氣是句型。這里是語氣的強(qiáng)調(diào),體現(xiàn)的方式是停頓,語速放慢,加重語氣等。

        希望大家重視細(xì)節(jié)題考點(diǎn),并且對自己錯的細(xì)節(jié)題進(jìn)行仔細(xì)地考點(diǎn)分析。
