until，since，for，from，by表时间的用法 before意为“在……之前”，在意思上与after相反。until/till意为“直到”，用于肯定句中时应与延续性的动词一块使用；用于否定句中应与表示瞬间动作的动词一块使用。 since后接表示时间点的词时，其意思为“自从……”，一般常用在含有现在完成进行时或现在完成时的句子中，表示句子中的谓语动词的动作从过去发生一直持续到现在。 for后加表时间段的时间状语，一般用于含有现在完成时的句子中，表谓语动词的动作一直持续了好久。 from后接表时间段的时间状语时，意思为”从……时间开始”，多用在“from…till/to ...”这一结构之中，表示谓语动词的动作从何时开始，而不说明谓语动词的动作能够持续多长时间，一般用在含有将来时、过去时或现在时的句子中。 by意为“不迟于，到……时止”，表某个动词发出的动作持续到某个时间点结束；“by+表示将来的时间点”用于含有将来完成时的句子中，“by+表示过去的时间点”用于含有过去完成时的句子中。 例1：___________ 2018，people here has grown more wheat instead of more corn. （填空） 解析：Since。本句中用到了现在完成时，表示人们种植了更多的小麦而不是玉米是从过去的2018年这个时间开始的，并且这个动作一直持续到了现在。2018年是一个时间点，since后加表时间点的词，意思为“自从……”，符合题意。 例2：These kind-hearted teenagers have taken care of the bedridden old man more than 8 months. 解析：for。more than 8 months意为“8个多月”，是一个时间段，表示某一动作持续了一段时间，应用介词for。 例3：October 20 is the day _________ which you must hand in your math homework.（填空） 解析：by。分析本句可知，本空应该填介词，介词与其后面的句子作定语修饰the day。根据句子意思可知应填by，意为“不迟于，到……时止”。 谷雨刷题王 速记英语单词方法 新概念英语青少版 Politeness is the practical application of good manners, the goal of which is to make all of the parties relaxed and comfortable.
