理清考試題目的考察重點有助於我們更快更好的掌握考試方法，以下本站小編整理的GMAT語法講解：狀語從句，希望對大家有所幫助，更多資訊請關注應屆畢業生網!
狀語從句的省略:
a)正確形式:
表示時間/條件/轉折/讓步的連詞(when/while/if/unless/although/even though/even if) + 形容詞短語/-ing短語/-ed短語
(邏輯主語等於句子主語) (所以when a child/ when children是錯的; if + n.也是錯的)
b)錯誤形式:表示時間/條件/轉折的連詞 + 介詞短語/名詞短語 (although just inside the orbit of Jupiter是錯的)(OG10-69)
c)特殊情況:once可以加介詞短語/名詞短語; whatever可以加名詞短語
d) 狀語從句省略的'條件：
第一點是毫無疑問的：邏輯主語等於句子主語
第二點也是必須的：從句的謂語必需是be(沒要求主句謂語也必須是be!換句話說可以看成是省略了一個be)，且從句主語和謂語要麼同省，要麼同留。
pronounce固定搭配
pronounce sb/sth (as) sth/adj:

amount
不能修飾可數名詞

economic 是”經濟上的”，economical是”節約的”。

錯誤搭配：possibility to do sth.

view sth. as sth.
而view sth. to be sth.錯誤。
announce固定搭配：
(1) announce something to somebody 或者 announce to somebody something (相當於賓語後置)
(2) announce a decision/intention/plan (在這個時候如果plan等後面接to do不會產生to do做狀語修飾announce的歧義)*:The government has announced plans to create 10,000 new jobs.
(3) announce (that)
(4) announce somebody/yourself 通報...的到達;通知...已準備好(注意這個短語有專門意思)
