2.begin的用法

动词begin的用法 1. 表示开始做某事，其后的动词可用不定式也可用动名词。

如： when did you begin to learn [learning] french？你什么时候开始学法语？ hearing the news she began to cry [crying]. 听到这消息她就哭了。 【注】当 begin 后接的是表示心里活动的动词（如 think, realize, understant 等）或 begin 本身为 -ing 形式时，其后通常要接不定式而不接动名词。

如： it is beginning to rain. 开始下雨了。 she began to understand. 她开始明白了（from ）。

2. 汉语说“从……开始”，英语一般不用 begin from，而应根据具体情况选用适当的介词。如： our journey began at changsha. 我们的旅行从长沙开始。

the sports meet begins on monday. 运动会从星期一开始。 3. begin 作为终止性动词，学生在很多地方容易出错。

如：音乐会已开始半小时了。误：the concert has begun for half an hour. 正：the concert has been on for half an hour. 三点钟下雨了。

误：it rained at three o'clock. 正：it began to rain at three o'clock. 比较：it was raining at three o'clock.。
