英語四級聽力技巧之計算類概述
計算題
M: When does the next shuttle bus leave?
W: You have just missed one by 20 minutes. We have a bus every 45 minutes, so you’llhave to wait for a while.
Q: How long does the man need to wait for the next bus?
A) 25 minutes B) 65 minutes
C) 20 minutes D) 45 minutes
【解析】 當(dāng)你看見這四個選項，不難發(fā)現(xiàn)這一題是在考與時間有關(guān)的內(nèi)容，并且從選項當(dāng)中可以推測到是考時間的加減關(guān)系，因為其中三個選項都是正確答案的干擾選項，說到這里，你就要做好充分的思想準(zhǔn)備。原文中除了聽清20和45兩個數(shù)字之外，重要的是明白其之間的聯(lián)系，通過missed知道已經(jīng)錯過，而介詞“by”專門用在計算題表差額;通過every知道每輛車之間45分鐘，問的是wait for the next bus 還得等多長時間，很清楚這里是減法的計算關(guān)系，所以選擇A。
細(xì)節(jié)辨認(rèn)題
M: I wonder if Jack will come here by 11 o’clock.
W: His wife said he left home at 10:30, so he should be here at 11:20 at the latest.
Q: What time did Jack leave home?
A) 11:20 B) 10:30 C) 10:50 D) 11:30
【解析】 原文中出現(xiàn)三個數(shù)字，11:00是Man覺得杰克應(yīng)該到的時間;10:30是杰克的妻子說他離開家的時間;11:20是Woman認(rèn)為杰克應(yīng)該到的時間。我們再來看問題，選B是對號入座。
【死馬活醫(yī)】 如果沒聽清，這里就要充分運(yùn)用技巧來猜選，時間中的B和C選項，可以合并小時“10”;時間中的B和D選項，可以合并分鐘“30”，通過合并同列項方法，就能猜選答案為B。
等值轉(zhuǎn)換題
M: These postcards cost 60 cents a dozen.
W: Two dozen should certainly do.
Q: How many postcards will the man buy?
A) 60 B) 12 C) 24 D) 16
【解析】 第一句話是“聲東擊西”，60美分一打，問題并不是我們所期待的考多少錢，考價格，而是在問數(shù)量，第二句話提到數(shù)量，但前面加了pair,意味著要乘以2。除了清楚這些還不夠，dozen是英語中數(shù)字的代用詞，表示12。所以選C。
常見的數(shù)字計算類提問形式：
1. What time…? 5. How far…?
2. How much/many…? 6. How often…?
3. How long…? 7. How old…?
4. When…?
