【Grammar】

1. -ed形式作定语

（1）及物动词的－ed形式表被动完成

，如：

a respected leader 受尊敬的领导 abandoned farms 被遗弃的农场

oppressed people 被压迫的人们 steamed bread 馒头

动词的-ed 形式作定语说明所修饰的名词的状态，-ed形式在一定程度上失去了被动的意义，而是一个形容词。如：

puzzled look 疑惑的表情 disappointed children沮丧的孩子们

tired people 疲惫的人 satisfied expression满意的神情

（2）不及物动词的-ed 形式一般不表示被动的意义，只表示完成意义。可这样用的只有少数表示位置转移或状态改变的-ed 形式。如：

the gone days 逝去的日子 fallen leaves 落叶

risen sun升起的太阳 a retired teacher退休教师

（3）动词的-ed 形式可构成合成词作前置定语，如：

widely-used language广泛应用的语言

man-made satellite人造卫星

highly-developed industry高度发展的工业

（4）分词短语常放在被修饰的名词之后作后置定语, 与其修饰的词是被动关系，相当于一个被动

语态的定语从句。如：

a letter written in pencil = a letter which was written in pencil 用铅笔写的信

a woman called Li Hua = a woman who / that is called Li Hua 一个叫李华的女士

Most of the people invited to the party were famous scientists. (=who were invited to the party). 被邀请到聚会上的大多数人是著名的科学家。

注意：个别分词如given, left 等作定语放在被修饰词后面

This is the question given. 这是所给的问题。

There's no money left. 没有剩下的钱了。

2. 一般过去时

（1）表示过去某一特定时间所发生的、可完成的动作或状态，常与表示确切过去时间的词、短语或从句连用。

表过去的时间状语如：yesterday, last night, five years ago, just now, in those days, the other day, during the day, until the 1920s, in 1925. 如：

We went to the cinema last night and saw a very interesting film. I played football every day when I was a boy. （2）

表示过去习惯性的动作。如：

I used to do my homework in the library. He always went to class last. (3)在一些固定句型中用过去时表示虚拟。

Would you mind if sb. did…?

It is time sb. did sth“早该…”

would (had) rather sb. did sth“宁愿某人…”

Would you mind if I smoked here? It is time you went to bed. I'd rather you came tomorrow. Step 2小组合作讨论解决疑难问题
