原狀because of, owing to, due to 表語形容詞
例：Owing to our joint efforts, the task was fulfilled ahead of schedule. 由于我們的共同努力，任務提前完成了。
注：Owing to 和because of 都做原因狀語，而due to 只能做表語形容詞。所以此句。owing to 的介詞短語做原因狀語。

before, after 表一點，ago, later 表示一段
即before, after 常表示一個點的時間狀語，而ago，later 常表示一段的時間狀語。
例如：前天the day before yesterday;前年the year before last; 大上星期the week before last 等等都表示點狀語的。
要想準確無誤地使用好before 和ago, after 和later 比較困難，但要是以"點"和"段"來區(qū)別就容易得多。
例：晚飯前before supper
解放前before liberation
1970 年前before 1970
*前before cultural revolution
國慶前before National Day
入大學前before coming to college
這些都是"點"狀語，因為1970 年前即1970 年1 月1日前。國慶節(jié)即10 月1 日前。
ago 表示一段時間。
例：一分鐘前a minute ago
半小時前half an hour ago
兩天前two days ago
一星期前a week ago
五年前five years ago
因為a minute, half an hour, two days, a week, five years等都表示一段時間，所以用ago。以及ten days later 等皆如此。
before 可接完成時，ago 過去級有限
這時的before 是連詞(也可做介詞)
例：We had scarcely left our school before it began to rain. 我們剛離開學校，天就下雨了。(完成時)
I had studied French for four months before I came here. 我來這兒以前就已學了四個月法語了。(before 接完成時)

since以來during 間，since 時態(tài)多變換

即beside 的一般用法是"在......旁邊", 但還有"和......相比"等特殊用法。
例：I feIt so weak in spoken English beside them. 和他們相比，我感到我的口語太差。
Beside work and study, all else was trivial. 同工作和學習比起來，其他一切都是小事。
除了last but one，即but 多指"除了"的意思，也有"倒數(shù)第幾"的意思。last but one 即不是后一個。
例：I haven't told anybody but one. 除了我愛人，我誰也沒告訴。(除了)
Who but a fool would study foreign language well if he is a hard working one. 如果他勤奮好學的話，除了傻瓜誰都能學好外語。(除了)

所謂工、學、軍、城、上、北、南，是說up 和down 的用法。這也是漢英翻譯時要注意的。例如：招工，上大學，參軍，進城，上山，向北方等都屬于up。而相反的下鄉(xiāng)，向南，落榜等都屬于down。"大軍南下，北上抗日"大概由此而來。
but for 否定用虛擬，復合介詞待后言。
but for是"若不是"的意思。
例：But for our great Communist Party, we could never have today's happiness. 若沒有偉大的共產(chǎn)黨，我們決不會有今天的幸福生活。

即before, after 常表示一個點的時間狀語，而ago，later 常表示一段的時間狀語。
例如：前天the day before yesterday;前年the year before last; 大上星期the week before last 等等都表示點狀語的。
要想準確無誤地使用好before 和ago, after 和later 比較困難，但要是以"點"和"段"來區(qū)別就容易得多。
例：晚飯前before supper
解放前before liberation
1970 年前before 1970
*前before cultural revolution
國慶前before National Day
入大學前before coming to college
這些都是"點"狀語，因為1970 年前即1970 年1 月1日前。國慶節(jié)即10 月1 日前。
ago 表示一段時間。
例：一分鐘前a minute ago
半小時前half an hour ago
兩天前two days ago
一星期前a week ago
五年前five years ago
因為a minute, half an hour, two days, a week, five years等都表示一段時間，所以用ago。以及ten days later 等皆如此。
before 可接完成時，ago 過去級有限
這時的before 是連詞(也可做介詞)
例：We had scarcely left our school before it began to rain. 我們剛離開學校，天就下雨了。(完成時)
I had studied French for four months before I came here. 我來這兒以前就已學了四個月法語了。(before 接完成時)

since以來during 間，since 時態(tài)多變換

例：I feIt so weak in spoken English beside them. 和他們相比，我感到我的口語太差。
Beside work and study, all else was trivial. 同工作和學習比起來，其他一切都是小事。

所謂工、學、軍、城、上、北、南，是說up 和down 的用法。這也是漢英翻譯時要注意的。例如：招工，上大學，參軍，進城，上山，向北方等都屬于up。而相反的下鄉(xiāng)，向南，落榜等都屬于down。"大軍南下，北上抗日"大概由此而來。
