    這是屬於分辭構句的的用法,請看下列分解。

    ★★『Participial Construction』分詞構句

    Participle真正精采的用法是Participial Construction (分詞構句)

    先以下列例句讓各位施主觀賞。

    Having reached the end of my poor sinner's life, my hair now white, I grow old as the world does, waiting to be lost in the bottomless pit of silent and deserted divinity, sharing in the light of angelic intelligences

    當我可憐罪人生命的終點來臨時,此刻我的頭髮已斑白,如同這個世界的更迭我也變老了,等待迷失在靜默且凡俗的深淵中,並分享著天使智慧的靈光。 (節譯: The Name of The Rose – Umberto Eco)

    Having reached... = When I have reached...

    為什麼前子句的主詞是 "I" ? --- 因為「前子句的主詞」與「後子句的主詞」相同,

    所以省略不用。為了讓句子更精簡,連接詞when也跟著省略了。

    waiting to be... =, and I waited to be...

    sharing in the light... = and I shared in the light...

    上述兩個子句的主詞仍然是 "I",只是連接詞and也一併省略了。

    句子形成方法如下: After I had done my work, I went out for a walk.

    (1) 去掉連接詞 --- After I had done my work, I went out for a walk.

    (2) 去掉副詞子句的主詞 --- I had done my work, I went out for a walk.

    (3) 動詞改為分詞 --- Having done my work, I went out for a walk.

    礙於篇幅受限請參考下列網址

    分解如下:

    When entering the building, => 分辭構句

    please sign in at desk and get a visitor's pass. =>祈使句

    上述兩句皆省略了主詞;祈使句不再贅述主詞省略。

    至於分辭構句,其原句寫成 When you enter the building....,

    為什麼主詞是you呢? 因為後面的祈使句的主詞就是YOU。

    分辭構句的用法在於,前後子句主詞相同時。(請參考上述網頁)

    2007-07-12 00:46:07 補充:

    連接詞+分辭構句:這種用法是為了更明確地表示分辭構句的意思(表:時間,原因,讓步,條件,附帶狀況),可以在分辭構句前加適當的連接詞。

    例如:

    He rarely makes mistakes when writing French.

    (= He rarely makes mistakes when he writes French.)

    While fighting in Korea, he was taken prisoner.

    (=While he was fighting in Korea, he was taken prisoner.)

    2句(其中一句)省略主詞的用法,常常有變化題型出現,不限於此

    這是分詞構句用法...

    使用時機在於有一個連接詞連接從屬子句與主要子句時...

    而現在分詞表主動,過去分詞表被動

    當前後子句主詞相同...則分詞構句主詞可省略

    EX. After he opens the door, he sees nobody.

    =After opening the door, he sees nobody.(前後子句主詞相同)

    =Opening the door, he sees nobody. (也可以省略連接詞)

    而若主詞不相同則主詞不可省略

    EX.Because it was a rainy day, very few people came to the camp.

    =Because it being a rainy day, very few people came to the camp.

    =It being a rainy day, very few people came to the camp.

    至於When entering the building中

    entering為現在分詞

    building為名詞=>建築物

    When entering the building 是副詞子句

    please sign in at desk and get a visitor's pass 是主要子句

    When entering the building, please sign in at desk and get a visitor's pass.

    等於Please sign in at desk and get a visitor's pass, when entering the building

    When + 副詞子句,

    像是when、before、after這種句子前面主要子句跟後面副詞子句主詞一樣時,

    可以省略when、before、after接的副詞子句的主詞。

    所以主詞被省略後,

    接在when這個介係詞的後面的動詞enter就必須變成動名詞entering。

    2007-07-12 00:42:12 補充:

    building 是動詞變成名詞。

    building跟entering改變原來形式原因是不一樣的歐!

    enter變動名詞是因為省略主詞後,接在介係詞後面。

    build變成名詞是因為在這副詞子句裡,它扮演的是名詞的角色。

    When entering the building, please sign in at desk and get a visitor's pass.

    其實這一整句是個祈使句, 而省略了主詞的部份

    When entering the building 是表明一個時間點, 這個時間點不是在哪一天, 也不是在幾點, 而是在 "你進來的時候"

    也可以把句子改成 : Please sign in at desk and get a visitor's pass when you enter the building.

    因為要強調 "你進來的那個時候" , 所以把 when you enter the building 移到前面, 變成 When you enter the building, please sign in at desk and get a visitor's pass.

    希望對你有幫助
