| | 在汉英笔译、英语写作及听力中，经常会遇到数字；哪些场合用单词表示，哪些场合用阿拉伯数字表示，往往让人难以确定，现行语法书中也极少涉及此类问题。 实际上，以英语为母语的国家，在书写数字时已形成几条约定俗成的规则，现总结如下供读者参考。
一、英美等国的出版社在排版时遵循一条原则，即1至10用单词表示，10以上的数目用阿拉伯数字（也有的以100为界限），这条原则值得我们借鉴。
That table measures ten feet by five.
那个工作台长10英尺，宽5英尺。
The traditional pattern of classroom experience at the college level brings the professor a group of 20 to 30 students together for a 45-to-50-minute class session two or three times a week.
大学课堂的传统的教学方式是，一个教授和二三十名学生每周见面两三次，每次授课时间45到50分钟。
二. 人数用阿拉伯数字表示显得更简洁明了，但不定数量、近似值用单词表示较恰当。
There are 203817 voters on the electoral rolls.
选举名单上有203817个投票人。
Nearly thirty thous voters took part in this election.
近3万个投票人参加了这次选举。
三. 遇到日期、百分比、带单位的特殊数字，通常用阿拉伯数字。
Maximum swivel of table is l20.
工作台的最大旋转角度是120度。
Eg. 3rd March l991或3 March l991；
a discount of 5 percent（5％的折扣）；
purchased 7 yards of carpet（买7码地毯）；
ordered 2 pounds of minced steak（订购2磅肉馅）
如果涉及的数目和单位是不定数，可用单词表示。
about five miles per hour（每小时大约5英里）
at least ten yards away（至少有10码远）
hesitated for a moment or two（犹豫了片刻）
I have warned you a hundred times（我已经警告你多少遍了。）
四. 在科技文章中，数字频繁出现，用阿拉伯数字比用单词陈述更有利。
The new engine has a capacity of 4.3 litres a power output of 153 kilowatts at 4400 revolutions per minute. 这台新发动机的容积为4.3升，转速为每分钟4400转，时输出功率是153千瓦。
We know that the weight of a cubic foot of air at 0?C 76cm，pressure is 0.08l pound, or 12 cubic feet of air weigh a pound.
我们知道，1立方英尺的空气在0摄氏度和760毫米汞柱压力下，重量是0.81磅，也就是说12立方英尺空气的重量是1磅。
五. 句首不用阿拉伯数字，句末要尽量避免用阿拉伯数字。
4th July is an important date in American history.
应该写成The fourth of July...
19 couples took part in the ballroom dancing competition.
19对选手参加了交际舞比赛。 总有人会问怎样学英语效果最好，其实这个问题是没有统一的答案的，这里有一些学习英语的建议，希望能对大家有所帮助。
Warming-up to Study English
学习之前先热身
Just as there are exercises to help you warm up before you play some basketball or other sport, there are exercises which can help you warm up to study English. Here are some simple exercises to help you warm up.
每次打篮球或者进行其他运动之前我们总要做一些热身活动来准备准备，学英语也是一样，这里有一些可以帮你做学前热身的简单练习。
Study English I: Activating Your Vocabulary
热身练习一：激活你的词汇
Activate your vocabulary by thinking or speaking briefly about the subject you are about to work on. For example, if you are going to study English on topics that focuses on vacations, take a moment to think about your last vacation, what you did, what you enjoyed, etc. This simple exercise will help your brain warm-up to vocabulary that you are likely to encounter as you study English about this particular subject.
激活英语词汇可以通过简短的想想或者说一说和你即将学习的主题来进行。举个例子，如果你要学习和假期有关的主题，花点时间想想你上一个假期，你干什么了，你喜欢的事情等等，这个简单的练习可以让你的大脑准备好你在学习的时候可能用到的词汇。
Study English II: Activating Your Grammar
热身练习二：激活你的语法
Activate your grammar by thinking about the general grammar area before you begin to study. For example, if you are going to study English grammar focusing on the past, stop to think about what you did last weekend, where you went, etc. to help activate what you already underst about using the past. As with activating vocabulary, you ’ll help your brain bring up what it knows about the past simple in an easy way before you begin to focus on studying English grammar in detail.
在开始学习之前，想一想通用的语法点，以此来激活你的语法。比如，如果你要学习过去时，开始想想你上周末干过什么，去过哪里等等，这些可以激活你已经学会的过去式的用法。加上已经激活的词汇，在你开始学习语法细节之前，就可以帮助你的大脑用一种轻松的方法了解过去时。
热身练习三：唱首歌
Before class begins, or before you sit down to study English sing a song in English to yourself. Make sure to use a song that you underst know very well. This short fun exercise will help your brain focus on the English language in a relaxing manner. It ’s important to be relaxed when you study English! Singing a song also helps activate the creative side of your brain which can help you come up with more examples as your practice conversation or do some creative writing.
在英语课开始前，或者你开始学英语之前，给自己唱一首英语歌吧。最好是一首你完全明白唱的是什么的歌。这种简短又有趣的练习可以帮助你的大脑在放松模式下集中在英语这种语言上。学英语的时候放松是很重要的！唱歌还能帮助激活你大脑中有创造力的一边，者可以让你在练习对话或者写作的时候举出更多的例子。
Study English IV: Typing e a Short Paragraph in English
热身练习四：用英语写一段文章
If you going to study English at your desk, begin by typing a simple paragraph in English. You can type about your day, your hobbies, your friends, etc. Anything will do. Typing helps activate the kinetic part of your brain that helps improve learning through physical activity. I also recommend typing while you study your English grammar. This will help solidify your knowledge with movement.
如果你会坐在桌前学习英语，从打出一段简单的英文开始吧。你可以写写你的一天，你的爱好，你的朋友等等，什么都行。打字可以帮助激活你大脑中运动的部分，这有助于从生理行为方面促进学习。我还很推荐学语法的时候打字，这可以用动作固化你的记忆。
Study English V: A Thous Words ...
热身练习五：一千个词……
As the saying goes in English: A picture is worth a thous words. Help activate the creative side of your brain by trying to describe a photo or other image. You can combine use this also to activate your vocabulary by choosing a picture that has something to do with the subject your are going to study in English.
英语里有句话说，一幅画顶一千个词。描绘一张照片或者其他的图片会很有助于激活你大脑中创造性的一边。你还可以用一张和你要学习的主题相关的图片结合这个方法激活你的词汇。 |
