1. Adverb Clause of Time 連接時間副詞從句與主句的詞常見的有： when, while, whenever, as, as soon as, once, as long as, until(till), since, after, before 例如： When money speaks, truth keeps silence. ﹝當金錢一開口，真理就保持靜默。﹞ * "when"意指「當﹝一剎那﹞」 。 * 副詞從句可放在主句前或後，放在主句前，通常用逗號與主句隔開。 * 這例句運用擬人法。

Come when you please. Strike while the iron is hot.﹝打鐵趁熱。﹞ * "while"意指「當﹝一段時間﹞」 。

When (he was) young, he was not happy. * 副詞從句的動詞用 be，而又與主要子句的主語相同，則副詞從句的主語 及 be 動詞可一起省略。

I learned English while (I was) in London. Who took your place while you were ill? * 病了一段時間，不能用 "when"。

Whenever you go, I will follow you. * "whenever" 意指「無論何時」 。

We have both changed since we parted. It is five years since I saw her last. How long is it since he went to London? * 有些文法書認為主句所表達的，與其說是時間的經過，不如說是 時間的長短，因此應用 Simple Present Tense 。例如： It is ten years since I last saw him. 或 How long is it since you had a raise in salary ? 但英美人士卻覺得非常奇怪，他們通常會說： It has been ten years since I last saw him. 或 How long has it been since you had a raise in salary? 不過，也有例外的情況，若表示從過去到現在並沒有改變的性格， 則可以用 Simple Present Tense。例如： She is nervous about riding in a car since she was involved in the car accident. I left before he arrived. ( 或 I had left before he arrived.)

﹝他到達之前，我己離開了。﹞ He arrived after I left. ( 或 He arrived after I had left.) ﹝我離開後，他才到達。﹞ 2. Adverb Clause of Place 連接地點副詞從句與主句的詞主要有： where, wherever, whence, whither 例如： 2

Although (Though) my heart is breaking, I must smile. 2. My heart is breaking, but I must smile. 3. Although (Though) my heart is breaking, yet (still) I must smile. 4. My heart is breaking, yet (still) I must smile. 5. Although (Though) my heart is breaking, but I must smile. ﹝錯誤﹞ * "yet" "still" 副詞。

Do in Rome as the Romans do.﹝入鄉隨俗。﹞ He acts as if he were crazy. * "as if"意指「恰如﹝並非完全一樣﹞」 。 * "as if" 從句的動詞用假設語氣，因此用 "were"。 不過，在現代口語，有時亦用直說方式﹝現在時態、過去時態、 未來時態等﹞代替假設方式﹝過去時態、過去完成時態﹞。 假設方式強調「非現實性」，直說方式則著重「可能性」 。 以前，英文文法規定，在 as if 從句中要用假設方式，例如： It looks as if it would rain. 現代英文文法漸改用簡潔的直說方式，例如： It looks as if it will rain.

The baby laughed as if he had understood your expression. He speaks English as though he were an Englishman. * "as though" 意指「恰如」 。

I am as busy as a bee. He is as poor as you (are). ※ 若從句與主句的動詞時態相同，則 "are" 可隱藏； 若從句與主句的動詞時態不不同，則 "are" 不可隱藏。 例如： He is as poor as you were.﹝他現在一如你過去那麼窮。﹞ He was as poor as you are.﹝他過去一如你現在那麼窮。﹞ He was as poor as you (were).﹝他過去一如你過去那麼窮。﹞ She is as tall as he (is). She is not as tall as he (is). She is not so tall as he (is). 6

* "as…as" 在肯定句或否定句中皆可用，而 "so…as" 只在否定句中使用。

I cannot do it so quickly as you. Mr. Lee is not so old as he looks. ※ 在未介紹 "than" 這個從屬連詞的用法前，先介紹形容詞的比較級 和最高級。為了表達形容詞的不同程度，形容詞可分三級： 1. 原級 Positive Degree 2. 比較級 Comparative Degree 3. 最高級 Superlative Degree ※ 形容詞的比較級和最高級的形成規則如下： 1. 單音節詞： a) 通常在原級後加 er 成比較級，加 est 成最高級。例如： great → greater → greatest tall → taller → tallest b) 若以 e 收尾，則加 r 成比較級，加 st 成最高級。例如： large → larger → largest c) 若以輔音字母收尾，而輔音字母前是元音字母，則先重複輔音 字母，加 er 成比較級，加 est 成最高級。例如： big → bigger → biggest fat → fatter → fattest 2. 雙音節詞： a) 通常在原級後加 er 成比較級，加 est 成最高級。例如： clever → cleverer → cleverest narrow → narrower → narrowest b) 若以 e 收尾，則加 r 成比較級，加 st 成最高級。例如： able → abler → ablest c) 若以 y 收尾，而 y 前是輔音字母，則改 y 為 i ，加 er 成 比較級，加 est 成最高級。例如： happy → happier → happiest lucky → luckier → luckiest 3. 多音節詞： 在前面加 more 成比較級，加 most 成最高級。例如： beautiful → more beautiful → most beautiful important → more important → most important 4. 還有一些單詞的比較級和最高級是不規則的： 原級 比較級 最高級 good / well better best bad / ill worse woest 7

many / much little far old

more less farther / further older / elder

※ 根據條件副詞從句所表示的假設情況是否可能實現，可分以下 幾種類型： A. 表示假設情況有可能或很可能實現 句式：從句﹝if + 動詞現在式﹞ / 主句﹝will / may /… + 原型﹞ 8

例如： If I have time, I will visit you. If it rains, bring me my umbrella. B. 表示假設情況不可能實現並且跟現在的事實相反 句式：從句﹝if + 動詞過去式﹞ / 主句﹝would / should + 原型﹞ 例如： If I had money, I should lend you some. ﹝如果我有錢【現在沒有】，我會借一些給你。﹞ If I were a bird, I would fly to you at once. ﹝如果我是一隻鳥【現在不是】，我立刻飛到你那裡去。﹞ If I were a king, you would be a queen. ﹝如果我是皇帝【現在不是】，你就是皇后。﹞ If I knew English, I would talk with the American businessman. ﹝如果我懂英語【現在不懂】，我會跟那個美國商人商談。﹞ C. 假設情況不可能實現並且跟過去的事實相反 句式：從句﹝if + had + 過去分詞﹞ / 主句﹝would / should + have + 過去分詞﹞ 例如：

If you had reached the station earlier, you should have caught the train. ﹝如果你早些到達火車站【剛才沒有早到】，你應趕上那班火車。﹞ If I had seen him yesterday, I would have told him the news. ﹝如果我昨天見到他【昨天沒有見到】，我會告訴他這個消息。﹞
