时间表示法和时段的简单运算是听力考试的热点,请看下面的对话:
W: How long does the class usually last?
M: Umm, let me think. It starts from a quarter to nine, and ends at nine thirty. So...
W: That is forty??five minutes. Thank you very much!
Q: When does the class usually start?
3.英语中货币的表达方法
英国货币:penny(便士)/pence (penny的复数),pound (£)
£20.50:twenty pounds fifty pence,也可以简单地写作:twenty fifty
美国货币:
1美元钞票a S|1.00 bill
1 dollar=100 cents
(S|1.00=one dollar)
(S|2.00=two dollars)
25美分1 quarter
10美分1 dime
5美元1 nickel
1美分1 penny
S|15.95:fifteen dollars ninety-five cents,或fifteen ninety-five.
(注:表示正常价格: regular price, normal price.
表示价格划算:a good buy, a better buy, an excellent price, a good price/ bargain.
表示价格较贵:dear, expensive, more expensive, steep.
表示价格便宜:cheap, inexpensive, bargain price, less expensive.
表示减价出售:sale price, on sale, garage sale, Christmas sale, special price.
词组:discount, half, double, cut off, knock off, twice as much as ,cross off, etc.)
4.英语中关于数字及其计算的听力考点
(1)数字辨别:
有关数字辨别的一个关键考点就是类似30/13,40/14,50/15,60/16的听音,看大家能否听出其发音区别。听力理解中难以分辨的基数词主要有以下几对:
thirteen与thirty; fourteen与forty; fifteen与fifty; sixteen与sixty; seventeen与seventy;eighteen与eighty; nineteen与ninety,在英文中这几对数词叫做teens and tens(十几与几十)。
不管加减还是乘除,这类题中至少会出现两个数字,你的任务就是迅速地判断这两者的关系,然后根据听音再确定正确选项。
(2)加减法计算:
在需要简单的加减法计算的题型中,对话中至少出现两个数字,它们之间的关系往往用“多少”、“迟早”、“快慢”、“前后”的形容词、副词或介词短语等来表达。还要注意一些能够表示数的存在或引起数的变化的动词,这些动词也能确定数字之间的加减关系,例如:
be, have, start, begin, spend, miss, leave, postpone, prolong, increase, add, borrow, lend, loan, delay, save, go up, go down, rate, at x% off the price等。
大家还应该记住下面这些表示加减关系的词:
more(多),less(少),late(晚),early(早),fast(快),slow(慢),before(前),after(后),add/addition(加上),plus(加上),subtract/ subtraction(减去),minus(减去)
Dialogue 1:
M: This black bag is 2.00 and that blue one is a dollar more.
W: The red one is twice as much as the blue one.
Q: How much are two red bags?
A.S|4.00B.S|6.00
C.S|8.00D.S|12.00
这道题从选择项上来看非常简单,因为数字不大,所以乍一看选择项有可能放松警惕,而实际上,这道貌似简单的题,中间却暗含着陷阱。因为原文中提到black、blue、red三个颜色的bag,最后提问的是红色书包的价格,包含了一个加法和乘法运算。如果大家在听的时候没记好,又没有做好笔记,就很容易出错。因此,在听力答题中要保持一个清醒的头脑,稳扎稳打是成功的重要保证。
Dialogue 2:
W: Three hours ago, I saw Bob at a meeting. Is he home yet?
M: No. He said he would be back at four and it??s six already.
Question: What time did the woman see Bob?
A??2∶00 B??3∶00 C??5∶00 D??6∶00
在这个例子中,见到Bob的具体时间必须依据现在的时间推断出。现在时间是6点钟,而说话人是在三小时之前见到Bob的,因而那时的时间约是3点钟。正确的选项是B.
