官方真題Official7托福聽力Lecture4原文文本

Narrator: Listen to part of a lecture in a Geology class.

Pro: Last time, we started to talk about glaciers and how these masses of ice form from crystallized snow. Some of you were amazed at how huge some of these glaciers are. It may be difficult to understand how a huge mass of ice can move or flow, but it is known that glaciers flow due to gravity. However, the way they flow needs some explaining.

The first type of glacier flow is called: basal slip. This refers to the sliding of a glacier across bedrock, actually across a thin layer of water on top of the bedrock. The ice at the base of the glacier is under significant pressure from the weight of the overlying ice.

Under pressure, the melting temperature of ice is reduced, meaning that ice at the base can melt even below zero degrees Celsius. This creates a thin layer of water between the glacier and the ground, reducing friction and allowing the glacier to slide over the bedrock.

Next, we discuss deformation. Ice is both brittle and plastic; it can change shape without breaking. For instance, if a bar of ice is supported only at one end, the unsupported end will deform under its own weight, flattening out and getting distorted. Deformation can be thought of as a very slow oozing where the ice crystals reorganize and realign, allowing the glacier to ooze downhill without melting.

Factors affecting deformation include the thickness of the ice and temperature. Thicker ice experiences more deformation due to gravitational forces. Additionally, ice closer to its melting point moves more easily than colder ice, similar to how oil behaves at different temperatures.

Now, let’s briefly touch on extension and compression. These are included in your textbook as types of glacier movement, though many sources omit them. The upper parts of glaciers have less pressure and are more brittle, leading to the formation of crevasses when they encounter stress but cannot deform quickly enough.

Glaciers generally move slowly, but during surges, they can move at speeds up to 7000 meters per year, which is hundreds of times faster than normal movement. Such speeds are unusual but can be observed during these rare surges.

對于許多托?？忌鷣碚f,，聽力部分常常是一個挑戰(zhàn)。為了幫助大家更好地理解托福聽力的真題,，我將在這篇文章中分享一些實用的解析方法和備考經(jīng)驗,，希望能對你的復(fù)習(xí)有所幫助。??

一,、了解托福聽力考試結(jié)構(gòu)

托福聽力部分通常包含 4-6 段聽力材料,，每段材料后會有 5 道題目。這些聽力材料主要分為兩類：學(xué)術(shù)講座和日常對話,。掌握這些基本信息,，可以幫助你在考試時更有針對性地進(jìn)行聽取和理解。

二,、練習(xí)真題的重要性

使用 TOEFL Listening Practice Tests 是提升聽力能力的有效方式,。通過反復(fù)練習(xí)真題，你可以熟悉考試的題型和節(jié)奏,。例如,，以下是一道經(jīng)典的聽力題：

Listening Text: "The professor discusses the impact of climate change on polar bear populations."

Question: "What is one effect of climate change mentioned in the lecture?"

參考答案： "The melting ice caps are reducing the habitat for polar bears." ??

三、提高聽力技巧

在聽力練習(xí)中,，掌握一些技巧非常重要：

• 做好筆記： 在聽的過程中,，記錄下關(guān)鍵詞和主要觀點(diǎn)，這將幫助你在回答問題時更有依據(jù),。
• 預(yù)測內(nèi)容： 在聽之前,，先快速瀏覽題目，猜測可能出現(xiàn)的內(nèi)容,，這樣在聽的時候會更加專注,。
• 重復(fù)聽： 如果時間允許,，可以多聽幾遍同一段材料，以便更深入理解內(nèi)容,。

四,、常見題型解析

托福聽力題型多樣，以下是一些常見題型及其解析：

• 主旨大意題： 這些題目通常詢問聽力材料的主要觀點(diǎn)或主題,。建議在聽的過程中抓住每段材料的核心內(nèi)容,。
• 細(xì)節(jié)題： 關(guān)注具體信息，例如數(shù)字,、日期,、地點(diǎn)等。在材料中找到相關(guān)信息并加以確認(rèn),。
• 推理題： 需要根據(jù)聽到的信息進(jìn)行推理,，理解說話者的意圖或態(tài)度。
