由一個教授和十名學生每周會晤兩三次,每次授課時間45到50分鐘,是大學程度課堂教學的傳統方式。
二. 人數用阿技伯數字錶示顯得更簡潔明了,但不定數量、近似值用單詞表示較恰當。

選舉名單上有203817個投票人。
Eg. Nearly thirty thousand voters took part in this election.
近3萬個投票人參加了這次選舉。
三. 遇到日期、百分比、帶單位的特殊數字,通常用阿拉伯數字。
Eg. Maximum swivel of table is l20.
工作台的最大迴轉角度是120度。
Eg. 3rd March l991或3 March l991;
a discount of 5 percent(5%的折扣);
Eg. purchased 7 yards of carpet(買7碼地毯);
Eg. ordered 2 pounds of minced steak
(訂購2磅剁碎的肉)。
如果涉及的數目和單位是不定數,可用單詞表示。
Eg. about five miles per hour(每小時大約5英里)
Eg. at least ten yards away(至少有10碼遠)
Eg. hesitated for a moment or two(猶豫了片刻)
Eg. I have warned you a hundred times(我已經警告你多少遍了)。
四. 在科技文章中,數字頻繁出現,用阿拉伯數字比用單詞陳述更有利。
Eg. The new engine has a capacity of 4.3 litres and a power out-put of 153 kilowatts at 4400 revolutions per minute.
這台新發動機的容積為4.3升,轉速為每分鐘4400轉時輸出功率是153千瓦。
