| 标题 | become的过去式和过去分词是什么？ |
| 范文 | become的`用法 1.用作连系动词，其后可接名词、形容词、过去分词等作表语： He became a teacher at (the age of) 17.他17岁就当了老师。 The weather became warmer.天气变得暖和起来。 Soon the roombecame crowded.不一会儿房里就挤满了人。 注意：其后接过去分词时，可表示被动或结果；但表示被动时，其后一般不接by短语。比如不说：Soon the room became crowded bystudents. 2.become是终止性动词，因此要表示“成为…有多长时间”，英语不能将become与表示一段时间的词或短语连用： 他成为老师有十年了。 He became a teacher ten years ago. It’s ten years since he became a teacher. He has been a teacher for ten years. 3.become之后一般不接不定式表示“逐渐…” (此时可用come/begin＋不定式)： 正：He began [came] to like English.他开始喜欢英语起来。 正：He became ill yesterday.他昨天病了。 4. 用于习语become of,表示“发生”、“遭遇”等 (常与what连用)： What has become of the girl?这个女孩后来怎样了? I don’t know what will become of me if I fail this time.要是我这次不成功，我不知我会怎么样。 上一篇：字母Z开头的单词 下一篇：homework是可数名词吗为什么 |
