GrammarⅠ

1. 过去分词作定语时的位置

单个的过去分词作定语时，一般将其放在被修饰词之前，有时单个的过去分词也可以作后置定语，用以强调动作。例如：

They needed much more qualified teachers. 过去分词短语作定语要放在被修饰词的后面，作后置定语，其作用相当于一个被动语态的定语从句。

例如：We ate great meals cooked by experts. =We ate great meals which were cooked by experts. 2．及物动词的过去分词作定语表示完成和被动。例如：

The book written by this young man was a great success. 注意：由于不及物动词后不可以直接跟宾语，所以不及物动词的过去分词作定语只表示动作的完成，而没有被动的意义。例如：

落叶

fallen leaves 升起的太阳risen sun一位退休的老师a retired teacher 3. 有些过去分词失去了被动意义，而作形容词，表示“感到……的”，现在分词表示“令人……的”。

4．现在分词作定语和过去分词作定语的区别现在分词作定语时，它与被修饰词之间是主谓关系，即被修饰词是分词动作的执行者。分词所表示的时间一般应与句中的谓语动词所表示的时间相同。

例如：

The girl sitting at the desk is good at English.= The girl who is sitting at the desk is good at English.

Grammar Ⅱ

Past Tense Time Expressions 1. 主要表示在确定的过去时间里所发生的动作或存在的状态。常用的表示过去

的时间状语有: at that time, during his middle school years, last night/year/week /month, a week /month/ year ago , in the olddays，in the past，until the 1920s,

in 1925,one night , a long time ago 2. 表示过去的习惯性、重复性的动作,常用一定的时间状语或频度状语。

I played football every week when I was young. 小时候我每周都去踢足球。

3. 有些情况，没有明确的表过去的时间状语，但实际上动词的动作是过去发生的，应用过去时态。

I didn’t know you were so busy.我事先不知道你这么忙。

4. 规则动词的过去式是在原形动词后加-ed，要注意掌握不规则动词的过去式以及过去分词的形式。例如：admit（admitted, admitted）;buy（bought, bought）;see（saw, seen）;set（set, set）;mean（meant, meant）

5. 一般过去时的疑问句和否定句，要用“did或didn’t+动词原形”结构。
