英语听力练习：大数、小数、日期与趋势表达全攻略

Numbers were one of the first things you probably learned in English class, but many students have difficulty saying very big and very small numbers in English. In this lesson, you'll practice saying complicated numbers and learn how to talk about trends. It's common to confuse numbers like 13 and 30. This shows why it's important to put the stress on the correct syllable. In 13, the stress is on the second syllable, and in 30, the stress is on the first syllable. Let's move on to some bigger numbers, like 100, 435, or 1,000. In numbers that are bigger than 1,000, you can use the comma to separate the parts of the number. For example, 5,468, 10,000, or 75,120. For extremely large numbers, read them part by part, such as 3,209,611. Practice helps you get used to the rhythm of English numbers.

Now that you know how to say big numbers, let's learn small numbers, decimals and fractions. Here are some decimals: 1.5, 8.09, or 0.317. Each number after the decimal point is pronounced individually, for example 7.25 is said as seven point two five, not twenty-five. When saying an email address or website, the dot is pronounced differently than in numbers. Fractions are also important: 1/2, 1/3, 1/4, 1/5, etc. They can be challenging to pronounce because of the TH sound at the end, but they are essential for dates and ordinal numbers such as first, second, third, and fourth. Practicing these helps in both everyday life and formal English.

Special rules apply for money and dates. In English, prices are said differently from other decimals. For example, $4.95 is pronounced as four ninety-five. For larger sums, people often use the long form for clarity: $395.23 is read as three hundred ninety-five dollars and twenty-three cents. Years are divided into two parts: 1981 is nineteen eighty-one, 1762 is seventeen sixty-two. From the year 2000 onward, we say two thousand one, two thousand five, and from 2010, both twenty ten or two thousand ten are acceptable. For days, we use ordinals: September 3rd, January 25th. Note that British English writes dates as day-month-year, while American English uses month-day-year.

Finally, let’s talk about trends. To describe increases we can say sales went up, rose, increased, or climbed. To describe decreases we say sales went down, fell, dropped, or decreased. If there is no change, we say sales remained constant or stayed the same. For irregular movements we use fluctuated, or went up and down. We can also describe intensity: sales decreased slightly, or sales dropped dramatically. Gradual changes are expressed as sales gradually increased, while sudden ones use words like suddenly increased, jumped, or took off. Opposite expressions include plummeted, bottomed out, or reached a low point. These expressions are essential for business and data discussions.
