教学难点：

1．句型：一般过去时与一般现在时的比较和运用。

2．词汇：mobile phone，sentence等词的读音及动词过去式。

教学构想：

一般过去时表示在过去发生的事情，其时间状语一般是表示在过去，如yesterday，last week，an hour ago，in 1982等等，这一点是其典型的特征。虽然对于小学生来说，讲到的都是简单的一般过去时的构词和用法，但是实际上在课外已经涉及到它很多形式的变化，我们可以将一般过去时的构成做一个系统的划分：规则动词的过去式。1．一般情况下，在动词原形后面加-ed；look-looked，play-played，start-started。 2．以不发音e结尾的动词，在词尾直接加-d；live-lived，use-used。3．以“辅音字母+y”结尾的动词，先将y变为i，再加-ed；study-studied。4．以重读闭音节（辅音+元音+辅音）或r音节结尾，末尾只有一个辅音字母的动词，要先双写这个辅音字母后，再加-ed；stop-stopped，shop-shopped。在教学中，教师要注意区分。
