become的用法説明和搭配

　　1. 用作連繫動詞，其後可接名詞、形容詞、過去分詞等作表語：

The weather became warmer. 天氣變得暖和起來。

Soon the roombecame crowded. 不一會兒房裏就擠滿了人。

He became a teacher at (the age of) 17. 他17歲就當了老師。

注意：其後接過去分詞時，可表示被動或結果;但表示被動時，其後一般不接 by短語。比如不説：

Soon the room became crowded bystudents.

　　2. become 是終止性動詞，因此要表示“成為…有多長時間”，英語不能將become與表示一段時間的詞或短語連用：

他成為老師有十年了。

正：He has been a teacher for ten years.

正：He became a teacher ten years ago.

正：It’s ten years since he became a teacher.

誤：He has become a teacher for ten years.

　　3. become 之後一般不接不定式表示“逐漸…” (此時可用 come / begin+不定式)：

正：He became ill yesterday. 他昨天病了。

誤：He became to be ill yesterday.

正：He began [came] to like English. 他開始喜歡英語起來。

誤：He became to like English.

　　4. 用於習語 become of, 表示“發生”、“遭遇”等 (常與 what連用)：

What has become of the girl?　這個女孩後來怎樣了?

I don’t know what will become of me if I fail this time. 要是我這次不成功，我不知我會怎麼樣。
