② Somebody stole my camera from my hotel room.
somebody /'s mb di/ pron. 有人；某人 n. 重要人物
somebody 是復合不定代詞，相當于someone。復合不定代詞作主語時，謂語動詞要用單數形式。
There’s somebody at the door. 門口有個人。
Somebody is waiting for you. 有人在等你。
She must be somebody.
她肯定是個重要人物。
作名詞，重要人物

小貼士：表示價格的高低要用high或low，表示物品貴賤要用expensive 或cheap。
somebody (someone) 某人；重要人物→用于肯定句中，也可用于表示請求或建議的疑問句中。
anybody (anyone) 任何人→常用于否定句和疑問句中。
nobody (no one) 沒有人→表示否定含義
everybody (everyone)每個人
考點精講
拓展：一般情況下， some 與one，body，thing 構成的復合不定代詞用于肯定句中；any 與one，body，thing 構成的復合不定代詞用于否定句或疑問句中。

—Yes, I have something to tell you. 是的，我有些事要告訴你。
Did you see anyone interesting 你見過有趣的人嗎？
形容詞修飾anyone，somebody，something 等復合不定代詞時，形容詞需要后置。
考點精講
敲黑板：在表示建議、請求或希望對方作出肯定回答的疑問句中，仍然用含有some 的復合不定代詞。

考題5：[無錫] UNICEF, part of the United Nations, _____ in Europe in 1946 after World War II.
A. set up B. was set up C. took up D. was taken up
【點撥】set up 建立；take up 占據，占用。根據“in Europe in 1946 after World War II”可知這是聯合國兒童基金會的成立時間，因此應用set up 來表示“成立”，且句子應用一般過去時。主語為UNICEF，與動詞短語set up 存在邏輯上的被動關系，因此應用被動語態。
B

She gave the little girl some flowers．她給了那個小女孩一些花。→ The little girl was given some flowers by her.
（將間接賓語轉化為主語，則保留直接賓語）
They bought the children many good books.
他們給那些孩子買了許多好書。
→ Many good books were bought for the children by them.
（將直接賓語轉化為句子主語，此時間接賓語前通常加上介詞to 或for）
