until / till既可用作介词也可用作连词,引导状语。通常有以下几种用法: 一、 用于肯定句作"直到……为止"解时,主句的动词一般是延续到until / till所表示的时间为止。例如: 1. He waits until / till the children are asleep. 他等着直到孩子们睡熟。 2. I shall stay here until / till twelve o'clock. 我将留在这里一直到十二点钟。 二、 用于否定句作"在……以前"、"直到才"解时,主句的动词一般是非延续性的,它所表示的动作直到until / till 所表示的时间才发生。例如: 1. He didn't come until / till late in the morning. 他直到早上很迟才来。 2. He didn't arrive until / till the game had begun. 直到比赛开始他才到。 注意:主句为一般将来时,until / till引导的从句用一般现在时代替将来时。例如: He couldn't ride until / till he was fifteen years old. 他直到十五岁才会骑自行车。 三、 用于"not...until..."的句式可以转换成when 或after引导的时间状语从句,但主句必须要用肯定形式。例如: 1. They didn't get off until the train came to a complete stop.=They got off after the train came to a complete stop. 火车停了他们才下车。 2. The student won't come into the classroom until the teachers finish their work.=The students will come into the classroom when the teachers finish their work. 当老师们完成工作时,学生们将走进教室。 四、 用于延续性动词的肯定或否定句中,但含义不同。例如: 1. The meeting continued until / till 7:00. 会议一直开到七点。 2. We didn't have the meeting until /till 7:00. 直到七点我们才结束会议。 五、 用于"It is / was not until...that"或含有"not...until..."的强调结构中,其中的until不能改为till。例如: 1. It was not until the film had begun that he arrived. 直到电影开始他才到。 2. It is not until 8:00 that we begin our class every day. 我们每天八点开始上课。 六、 Not until放在句首时,句子要倒装,其中的until不能改为till 。例如: 1. Not until the last moment did he change his mind. 直到最后一刻他才改变主意。 2. Not until midnight did it stop raining. 直到午夜雨才停。 七、 句首通常只用until,不用till。例如: 1. Until then, I knew nothing at all about it. 在那之前,我对此事一无所知。 2. Until you told me I had no idea of it. 在你告诉我之前,我对此一无所知。 八、 某些固定词组或谚语中通常只用till。例如: 1. from morning till night 从早到晚。 2. up till now直到现在 (文/王仲家;英语辅导报初中教师版03~04学年第40期;版权归英语辅导报社所有,独家网络合作伙伴新浪教育,未经许可,不得以任何形式进行转载。) |
