Official2 TOEFL Listening Lecture 4 Transcript
Bode’s Law
Professor: OK, let’s get started. Today, I will discuss the discovery of the asteroid belt. I’ll begin by writing some numbers on the board. Here they are: We start with zero, then 3, ...6, ...12. Can anyone tell me what I’m doing?
Female student: Doubling the numbers?
Professor: Correct! I’m doubling them, so 2 times 12 is 24, and the next number after 24 would be…
Female student: 48.
Professor: Right, 48, then 96. Now, I’ll write another row of numbers below that. Tell me what I’m doing: 4, 7, 10 … How did I get this second row?
Male Student: Adding 4 to the first row?
Professor: Exactly! I added 4 to each number in the first row. The last two will be 52, 100, and now tell me what I’m doing.
Female Student: Inserting a decimal?
Professor: Yes, I divided all those numbers by 10 by adding a decimal point. Now, I’m going to write the names of the planets under these numbers: Mercury...Venus...Earth...Mars. So, what do these numbers represent? Do you remember from the reading?
Male Student: Is it the distance of the planets from the Sun?
Professor: Exactly, in astronomical units—not perfect, but quite close. The value for Mars is off by about 6 or 7 percent. It’s within 10 percent of the average distance to Mars from the Sun. However, I need to skip the one after Mars for now. Jupiter is around 5-point something, and Saturn is about 10 astronomical units from the Sun. This pattern is known as Bode’s Law.
It isn’t really a scientific law in the sense of predicting gravity mathematically, but it attempts to identify a pattern in the spacing of the planets. This was noticed by Bode hundreds of years ago. You can imagine there was significant interest in why the 2.8 spot in the pattern was missing, but nothing obvious was found with early telescopes. Then in the late 1700s, what happened? The discovery of…?
Female Student: Another planet?
Professor: Yes, the next planet out, Uranus—after Saturn. And look, Uranus fits nicely into the next spot in the pattern, not perfectly, but quite close. People became very excited about the validity of this pattern and the search for the missing object between Mars and Jupiter. Remember, telescopes were improving. So, people began searching for objects at that missing distance from the Sun, and in 1801, the object Ceres was discovered.
Ceres was located in the right place—the missing spot. However, it was too faint to be classified as a planet. It appeared like a small star. Because of its star-like appearance, it was named an “asteroid.” “Aster” is Greek for “star,” as in “astronomy.” Ceres was the first and is the largest of many objects found at that same distance, leading to the formation of the asteroid belt. Thus, the asteroid belt stands as the most notable success of Bode’s Law. That’s how the asteroid belt was discovered.

2托福聽力真題解析
對(duì)于許多托?？忌鷣碚f,，聽力部分常常是一個(gè)挑戰(zhàn)。為了幫助大家更好地應(yīng)對(duì)這一部分,，本文將分享一些關(guān)于“托福聽力真題解析”的經(jīng)驗(yàn)和技巧,。??
一、了解托福聽力的結(jié)構(gòu)
托福聽力部分通常由四到六段錄音組成,，每段錄音后會(huì)有相應(yīng)的問題,。這些錄音可能來自于大學(xué)講座、課堂討論或?qū)υ??？忌枰谟邢薜臅r(shí)間內(nèi)理解并記住關(guān)鍵信息。
二,、聽力材料的準(zhǔn)備
建議考生多聽一些托福聽力真題,，可以通過官網(wǎng)或其他學(xué)習(xí)資源獲取這些材料。以下是一些推薦的材料：
- Listening Practice Sets
- Official TOEFL iBT Tests
- TOEFL Test Prep Planner
通過反復(fù)練習(xí),，你可以提高自己的聽力技能,，熟悉考試的節(jié)奏和題型。
三,、重點(diǎn)標(biāo)記與筆記技巧
在聽錄音時(shí),，做好筆記是非常重要的。你可以嘗試使用縮寫和符號(hào)來記錄關(guān)鍵信息,。例如,，使用“->”表示因果關(guān)系，使用“&”表示并列關(guān)系,。這樣可以幫助你在回答問題時(shí)快速回憶起聽到的內(nèi)容,。
四、分析真題
在練習(xí)過程中,，分析真題是提升能力的關(guān)鍵,。以下是一些典型的聽力問題類型：
- What is the main idea of the lecture?
- What does the professor imply about…?
- According to the conversation, what are the two students discussing?
通過分析這些問題，你可以掌握出題的規(guī)律,，特別是在選擇答案時(shí)如何排除錯(cuò)誤選項(xiàng),。
五、模擬考試環(huán)境
為了提高考試時(shí)的適應(yīng)能力,，建議考生進(jìn)行模擬測(cè)試,。在模擬過程中，盡量保持真實(shí)的考試環(huán)境,，包括時(shí)間限制和不打擾的環(huán)境,。通過這種方式,，你可以更好地管理時(shí)間，并在緊張的情況下保持冷靜,。
六,、參考答案與反饋
在完成聽力練習(xí)后，及時(shí)查看參考答案是非常重要的,。通過對(duì)比自己的答案和正確答案,，可以找出自己在理解和記憶上的不足之處。以下是一個(gè)范例：
Listening Text: A professor discusses the impact of climate change on polar bears.
Question: What is the main concern regarding polar bears mentioned in the lecture?
Answer: The melting ice caps are threatening their habitat.
七,、關(guān)注新題與預(yù)測(cè)
隨著考試形式的不斷更新,，關(guān)注新題和預(yù)測(cè)變得尤為重要?？忌梢约尤胍恍┩懈淇既?，獲取最新的信息和經(jīng)驗(yàn)分享,。了解哪些話題是?？嫉模热绛h(huán)境,、教育,、科技等，可以幫助你在復(fù)習(xí)時(shí)有的放矢,。
八,、總結(jié)與反思
每次練習(xí)后，不妨花點(diǎn)時(shí)間進(jìn)行反思,，思考哪些地方做得好,，哪些地方需要改進(jìn)。保持積極的心態(tài),，相信自己的努力會(huì)帶來進(jìn)步,。??
希望以上分享能幫助到正在備考托福的你，祝你在考試中取得理想的成績(jī),！
