　　二、 本文重点语法讲解

　　本篇课文的重点是时间介词的用法。

　　这部分知识点实用性很强，在PET, BETS2 中是必考项目，也是新概念英语第二册的重点语法，同时在小升初考试中也是完形填空常考知识点。只要多比较，多练，通过造句子区分各个知识点，学生大部分都能将这部分知识点掌握好，尤其时想在考试中拿高分的学生，千万不要忽视这样的细节知识点哦！

　　让我们来看看具体的时间介词家族成员吧：

　　At：表示在某时刻，时间，阶段，如at noon 在中午，at night在夜晚，还有具体时刻at 12 o'clock等；时刻前的介词用at：at five to twelve作时间状语

　　In ：强调在一段时间内，如在早，午，晚in the morning, in the afteronno, in the evening.

　　课文中in twenty minutes' time 20分钟之后，in 表示在段时间以后，根据时态判别in 表示的含义。

　　在四季也用它in spring, 在具体某一年，某一月份都用in, 如in 2010, in May

　　On :表示在某一天（具体日期），某星期，某天早上，某天前夕等具体时间：on May 1st ,2010; on Monday, on a sunny morning,on Christmas Eve.

　　From …to 强调时间延续性：从……到……举个例子They are busy from morning till night.

　　During：在某段时间里During the holiday,she eats a lot.

　　Not ..until 直到。。才。这个词考得特多，比如PET中常常在写作第一题中让学生进行同意句转换，如：It is 12 o'clock.。 She comes late.可改为She doesn't come until 12 o'clock.划线的地方不许超过3个单词。

　　After ，Before这两个词 孩子们再熟悉不过了，一般放在时间状语从句中使用。After he finishes his work ,he goes shopping.[page]
