托福聽力的內(nèi)容涵蓋社會科學(xué)、自然科學(xué)、人文藝術(shù)等多個(gè)學(xué)科領(lǐng)域,這些材料將模擬真實(shí)的學(xué)術(shù)環(huán)境,幫助你們展示自己如何捕捉關(guān)鍵信息、理解細(xì)節(jié)與主旨、以及推斷言外之意的能力。本欄目將帶來托福聽力的節(jié)選,助您更好的養(yǎng)成托福難度的聽力習(xí)慣。
聽力原文及翻譯
Once you do that, you can compare the age of the zircon in the sandstone in your sample to the age of the zircon in the mountains. If the age of the zircon matches the age of one of your mountain ranges, then it means the sandstone actually used to be part of that particular mountain range. Is everybody with me on that? Good.
完成此操作后,您可以將樣本中砂巖中的鋯石年齡與山脈中的鋯石年齡進(jìn)行比較。如果鋯石的年齡與某座山脈的年齡相匹配,則意味著砂巖實(shí)際上曾經(jīng)是該特定山脈的一部分。大家同意我的觀點(diǎn)嗎?很好。
So, in this case, uranium-lead dating was used to establish that half of the sandstone in the samples was formed at the same time the Rocky Mountains and the Appalachian Mountains were formed. So, because of this new way of doing uranium-lead dating, we've been able to determine that one of our major assumptions about the Grand Canyon was wrong.
因此,在這種情況下,鈾鉛測年法用于確定樣本中一半的砂巖是在落基山脈和阿巴拉契亞山脈形成的同時(shí)形成的。因此,由于這種新的鈾鉛測年方法,我們能夠確定我們對大峽谷的主要假設(shè)之一是錯(cuò)誤的。
托福聽力不僅是對你們語言能力的考驗(yàn),更是對你們學(xué)習(xí)態(tài)度和策略的一次檢驗(yàn)。希望本欄目的內(nèi)容對您的托福學(xué)習(xí)有所幫助,您也可以訪問網(wǎng)站主頁,獲取最新的英語學(xué)習(xí)資料,全方位提升英語水平。
