托福独立写作数词用法规则详细介绍

托福独立写作数词规则： 数字/单词运用时机区分

当数词可以用至多两个英文单词表达时，尽量使用英文字母表示。因此，12以下的数字或整数一般都需要“写出来”，但在percent(百分比)前面一般直接使用阿拉伯数字，如：

Experts quickly realized that there were two possible explanations for the decline of sea otters: environmental pollution or attacks by predators. 专家很快认识到，海獭数量减少有两个可能的原因：环境污染或来自捕食者的攻击。

When the price difference between two products is small, for example, less than 5 percent in the case of eco-certified wood products, American consumers often choose on factories other than price. 当两种产品之间的价格差距非常的小(在环保认证木材制品的案例中，这种差距小于5%)，美国消费者会考虑生产厂商而不是价格。

托福独立写作数词规则：什么时候用阿拉伯数字

当数字需要用两个以上英文单词表达时，尽量使用阿拉伯数字表示，因此年份往往是直接用阿拉伯数字进行表示，如：

These animals could run very fast, reaching speeds up to 125 kilometers per hour. 这些动物奔跑速度非常快，可以达到每小时125千米。

Cane toads were introduced to Australia in 1935 with the expectation that they would protect farmers’ crops by eating harmful insects. 蔗蟾于1935年被引入澳大利亚，期待它们通过吃害虫来保护农民的庄稼。

托福独立写作数词规则： 句子开头不用阿拉伯数字

句子的开头一般不使用阿拉伯数字，如：15 couples were invited to participate in a survey that aimed to figure out the fatal elements leading to personal success.十五对夫妇被邀请参与到一项调查之中，该调查的目的是探究个人成功最重要的要素。

较好的表达方式为：Fifteen couples were invited to participate in a survey that aimed to figure out the fatal elements leading to personal success.

托福独立写作数词规则：小数分数用数字

表达小数(或分数)时，尽量使用数字，如：The government has spent over $12.4 million constructing new recreational facilities for local residents in the past few decades. 在过去的几十年间，政府花费了超过1240万元用于为当地居民建造新的娱乐设施。

保持身体健康的最直接方式就是“锻炼”(take exercise; have physical training)。

锻炼身体的方式很多，慢跑(jogging)，爬楼(climbing stairs)，爬山(climbing)，健身房(gymnasium; gym; fitness centre)器械锻炼(body building)，健美操(aerobics dancing[exercises])，篮球、足球、羽毛球(badminton)、网球(tennis)，游泳……

(就算你平时根本不锻炼也要)选择一个，说明为什么那种方式能给你带来好处以及带来了什么样的好处。

另外，中国学生还有让老外跌眼镜的：武术(wushu/kongfu);气功(qigong);太极(Tai Ji)——全都是拼音，老外还得看懂，难为批卷的人了。

『范文』

Scientists have discovered that one of the main methods of prolonging a person's life is to keep healthy. There are many different methods to keep in good shape, and one must choose those that are most appropriate for their own lifestyle. Personally, in order to keep healthy, I eat well, exercise, and get lots of rest.

Eating well is an excellent way to keep healthy. If one is constantly drinking pop or eating fried foods, they will not be able to keep a healthy weight. One must eat lots of vegetables and fruit, and stay away from all foods that are high in cholesterol. In order to maintain a low level of cholesterol in my diet, I tend to eat more fish rather than heavier meats. Fish is much healthier than red meat, and I find it much tastier as well.

Exercising is also very important to leading a healthy lifestyle. One should exercise for at least half an hour, three to four times a week. Exercise can include anything from going to the gym to "work out", to going on a long walk around the city. If I am particularly busy, I will walk up the Stairs to my apartment rather than taking the elevator. This provides me with the minimum amount of exercise necessary to stay fit.

The third thing I do to keep healthy is sleep well and often. I typically sleep for approximately eight and a half hours every night. Sleep is very important, as your body uses this rest time to heal itself. If one tries to live for long periods of time without sleep, they will quickly become haggard and disheveled. Sleep is absolutely necessary for a healthy life.

In conclusion, I find that eating well, exercising and sleeping often is the best way for me to keep healthy. If a person can change their lifestyle and incorporate these three ideas, they will be much better off for it. A person who leads a healthy lifestyle will be less likely to get sick, and they will live longer. 165. What is one thing you will do to improve your community? You have decided to give several hours of your time each month to improve the community where you live. What is one thing you will do to improve your community? Why? Use specific reasons and details to explain your choice.

『范文』

Fostering a sense of community in one's neighborhood is an excellent idea. When one knows one's neighbors, one can easily ask for favors or opinions on community issues. I think that if I were to spend a number of hours each week helping out my community, I would offer free computer lessons. If one hopes to succeed in business, it is of utmost importance that they learn how to use a computer. Most decent jobs require at least a basic amount of computer skills. By helping members of my community to get well-paying jobs, I would be helping out the community at large. If my neighbors have more disposable income, it is likely that they will give some money back to the community to improve all of our living situations.

Second, offering free computer lessons to neighbors would increase friendly dispositions between all members in the community. If neighbors meet each other during lesson times, it is more than possible that they will become friends. Many people meet their best friends during the educational process. This socialization could continue during my computer course, thus increasing the friendly atmosphere of the community.

Finally, helping members of the community learn to use a computer would allow them to have more fun. There are many entertaining activities one can occupy one's time with on the computer. The computer also offers the user the opportunity to "surf the Internet", which can be a great way to spend one's time. For example, a person can download movies from the Internet, which can be watched on lazy summer evenings, or cold winter nights.

Thus, I think that offering computer lessons to those in my community would be an excellent way to volunteer my time. Computers improve people's living situations in so many ways, and I would love to be a part of this process.
