1 辅音后才用's表所属所以Charles's friend佳(查尔斯一家人的朋友)，Charles' friend次(不知道是查尔斯一家人的，还是其中某一个人的
2 附加语插入句中用逗号隔开如the best way to see a country, unless you r pressed for time, is to travel on foot.如果并不强调，就不用逗号隔开
3 用法上，"6 April 1988"比"April 6, 1986"更好
4 Jr.是Junior的缩写
5 有两部分句意且第二部分用for, or, nor, while等连接时，第二句前面要用逗号隔开
6 两分句主语相同需要省略，连接词是but时第二分句前要加逗号，连接词是and时不用加
7 分号使句子间紧密度比句号高，但分号最好连接两个短句(短句更简洁有力)
8 断开的小句子时常用于口语中，表强调，常常不完整
9 发挥详述，同位，列举等作用时，冒号比破折号更正式，但感情更弱
10 "We are all in the gutter, but Some of us are looking at the stars"
11 破折号比括号使句子更轻松
12 主语和谓语之间的成分并不影响主谓一致原则
13 Horace admires Jessica more than I do.比Horace admires Jessica more than I.要好，因为把动词阐释清楚不会引起误会。
14 用简单的代词做主语，如不用Blake and myself stayed home.而用Blake and I stayed home
15 动名词前通常用所属名词，如my driving但口语中通常用宾格heard him driving
16 每段不讲求先总后分，显得文章具有活力
17 积极的语言比较直接生动如I shall always remember my first visit to Boston.比My first visit to Boston will always be remembered by me 更好(这就可以解释为什么正式文书中多用被动--显得没那么主观)
18 大众喜欢主动句，专业人士偏爱被动句
19 there be和...could be done 句型显得很敷衍，应改为主动句式There were a great number of dead leaves lying on the ground.应改为Dead leaves covered the ground.
20 语言简洁代表着有活力。
