19、 没想到你在这里。 三：1. 表示一系列的动作，尽管有先后，都用一般过去时，最后两个动词之间用and连结。如： He opened the door, rushed out and then disappeared. 他打开门，冲了出去，然后就消失了。 三、 一般过去时对谓语动词的过去式构成。分规则变化和不规则变化两种形式，不规则变化通常需要逐个记忆，规则变化则遵循以下原则： (1) 一般在动词后加-ed。如：playplayed, offeroffered, weighweighed, destroy destroyed, signsigned. (2) 在以字母e结尾的动词后，只加-d。如
20、：likeliked, provideprovided, hate hated, datedated。 (3) 在以“辅音字母+y”结尾的动词后，则改y为i，再加ed。如： study studied. (4)双写最后辅音字母，再加-ed。如：planplanned, referreferred, regretregretted, stop-stopped 第一部分：知识讲解 1Be动词在一般过去时中的变化： am 和is在一般过去时中变为was。 are在一般过去时中变为were。 带有was或were的句子，其否定、疑问的变化和is, am, are一样，即否定句在was或were后加no
