is standing at the door?A developing country needs country that/which is developing needs lived in a house facing the south 224。上述狀語從句在省略時，并非任何成分都可以省略而是遵循下面原則：（1）當(dāng)狀語從句的主語與主句的主語一致時且從句中含有BE動詞的某種形式時，可以省略狀語從句的主語和系動詞be，這時從句中可出現(xiàn)如下結(jié)構(gòu)：① 連詞（as, as if , once）+ 名詞如：Once(he was)a worker ,Pang Long now bees a famous ，現(xiàn)在變成一位著名的歌手。④連詞(when , while , though)+ 現(xiàn)在分詞如：While(he was)holding talks with President Hu Jintao , US President George thanked China for its important role in the SixParty ，感謝中國在六方會談中起的重要作用。d better not refer to the ，你最好不要查字典。Before leaving, turn off all the lights.(Before you leave, turn off all the lights.)走之前，請關(guān)閉所有的燈。注：as在引導(dǎo)時間狀語從句時，沒有這種省略現(xiàn)象。如：Send

，我都不想聽如此壞的報告。本文就此的構(gòu)成、特點(diǎn)及用法等作一較全面闡述,以幫助同學(xué)們掌握這一重要的語法知識。(with+名詞+介詞短語,作伴隨狀語。復(fù)合結(jié)構(gòu)中第一部分與第二部分語法上是賓語和賓語補(bǔ)足語關(guān)系,而在邏輯上,卻具有主謂關(guān)系,也就是說,可以用第一部分作主語,第二部分作謂語,構(gòu)成一個句子。,不定式、現(xiàn)在分詞、和過去分詞的區(qū)別： 在with結(jié)構(gòu)中,不定式、現(xiàn)在分詞作賓補(bǔ),表示主動,但是不定式表示將要發(fā)生的動作,而現(xiàn)在分詞表示正在發(fā)生或發(fā)生了的動作；過去分詞表示被動或完成。： with結(jié)構(gòu)屬于獨(dú)立主格結(jié)構(gòu),但在結(jié)構(gòu)上,with結(jié)構(gòu)由介詞with或without引導(dǎo),名詞前有冠詞、形容詞、所有格代詞或其它詞類所修飾,結(jié)構(gòu)較松散；而獨(dú)立主格結(jié)構(gòu)沒有with或without引導(dǎo),結(jié)構(gòu)嚴(yán)密,名詞前可用可不用修飾語。引導(dǎo)詞的角度（1）可以同時用于名詞性從句和狀語從句的引導(dǎo)詞：when
