五遍聽力法
把一段聽力內容練成可重複利用的英語輸入
不要只聽完就結束。把同一條內容拆成 5 遍，先抓大意，再解決語言點，再模仿、聽寫、複聽，最後把內容變成自己的表達。
第二遍
看英文字幕
解決生詞和難句，可以查字典、做簡短筆記。
第三遍
跟讀 shadowing
逐句模仿語音語調、節奏與重音，盡量貼近原聲。
第四遍
少量聽寫
挑幾句關鍵句做聽寫，訓練從聲音到句子的組織能力。
第五遍
無字幕複聽
查漏補缺，回到純聽，感受英語聲音和節奏。

📝 雅思口語對話文本
I want to describe a simple way we measure microplastic pollution in rivers and on beaches. A single spoonful of river sediment can contain thousands of tiny plastic particles. That small sample, a spoonful, is enough to alarm scientists. We often take a spoonful from the top layer and then sieve and inspect it under a microscope. In urban estuaries we found far higher concentrations than in remote mountain streams. Surprisingly, some protected bays showed lower counts than samples taken near busy storm drains. Samples are dried and weighed. We use sieves, microscopes and chemical tests to separate fibres and fragments. These fragments are durable and persist in the environment. The contamination is pervasive, meaning it appears almost everywhere we look. Microplastics accumulate in sediments and in soil after heavy rainfall and sewage overflows. That accumulation can harm invertebrates and birds, and may enter the food chain through crops irrigated with contaminated water. To help, communities should reduce single-use plastics and improve waste collection. The point is simple. Even a tiny amount in a spoonful of sand or mud reveals larger problems for ecosystems and human health.
📝 📚 雅思練習題
1
According to the speaker, what can a single spoonful of river sediment contain?
答案錯誤
正確答案:
A
解釋:
Correct: The speaker states that a single spoonful of river sediment can contain thousands of tiny plastic particles. Option B is wrong because the passage mentions plastic particles, not only organic matter. Option C is wrong because detectable contaminants are explicitly reported. Option D is wrong because large metal objects are not described as typical contents of a spoonful in this context.
2
Which locations did the speaker say had higher concentrations of microplastics?
答案錯誤
正確答案:
A
解釋:
Correct: The speaker reports finding far higher concentrations in urban estuaries. Option B is incorrect because mountain streams had lower levels. Option C is incorrect because protected bays were said to show lower counts than near storm drains. Option D is incorrect because the passage does not discuss open ocean surfaces; it focuses on sediments in rivers, estuaries and bays.
3
What methods did the speaker mention using to analyze samples?
答案錯誤
正確答案:
A
解釋:
Correct: The speaker lists sieves, microscopes and chemical tests. Option B is wrong because X-ray imaging and sonar were not mentioned. Option C is wrong because satellite monitoring is not discussed for sediment samples. Option D is wrong because the speaker specifies sieves and microscopes rather than only visual inspection.
4
What does the speaker imply is a reason small samples are useful?
答案錯誤
正確答案:
A
解釋:
Correct: The speaker implies that a small sample like a spoonful can reveal larger problems and wider contamination trends. Option B is wrong because the speaker describes additional analysis steps after sampling. Option C is wrong because the passage emphasizes contamination, not cleanliness. Option D is wrong because the focus is on plastic particles, not metal pollution.
5
What does the word 'pervasive' most nearly mean as used in the passage?
答案錯誤
正確答案:
A
解釋:
Correct: 'Pervasive' here is explained as appearing almost everywhere, so 'widespread' is correct. Option B is wrong because 'pervasive' does not mean temporary. Option C is wrong because 'pervasive' does not imply harmlessness. Option D is wrong because 'pervasive' means spread across many areas, not concentrated in one spot.
6
Which of the following is NOT presented as a consequence of microplastic accumulation?
答案錯誤
正確答案:
C
解釋:
Correct: The speaker does not claim that microplastic accumulation causes sewage overflows to disappear. Option A is mentioned as a harm. Option B is mentioned as a possible route into the food chain. Option D is mentioned by describing fragments as durable and persistent.
7
Why does the speaker recommend reducing single-use plastics?
答案錯誤
正確答案:
A
解釋:
Correct: The speaker recommends reducing single-use plastics to help lower microplastic pollution entering the environment. Option B is incorrect because single-use plastics do not dissolve immediately; the passage describes fragments as durable. Option C is incorrect and illogical; reducing plastics would not increase sample numbers. Option D is incorrect because the passage states sieves are used to separate fibres and fragments.
