以上例句中 when , where 和 why 作关系副词引导定语从句时，可以改为“介词 + 关系代 词 which”来引导；而引导同位语从句的 when , where 和 why 就不能这样改。

【 学法指要 】

单元重点词汇点拨

1 . forgive 为不规则动词，过去式为 forgave , 过去分词为 forgiven ; 意为“宽恕 ( 人、罪等 ) ，原谅，饶恕 ( 某人的行为 ) ”。例如：

She forgave her husband .

If you apologize , the teacher may forgive your negligence .

2 . insist 意为“一定要；坚持要求”，既可用作及物动词，也可用作不及物动词。当其作 不及物动词时，其后通常跟 on 或 upon 引起的短语。例如：

They insisted on an early decision .

The doctor insisted on operating on the patient at once .

He insisted upon going there on foot .

He insisted on my studying English together with them .

当 insist 用作及物动词时，通常用句型 insist + that 从句。从句中的谓语动词常用虚拟 语气，即用“should + 动词原形”，其中的 should 常可省略。例如：

I insisted that the meeting ( should be ) be put off .

She insisted that he daughter ( should ) go on to learn English after she left school .

We insisted that he should come to the party . ( = We insisted on his coming to the party . )

3 . own 用作形容词时，意为“自己的，自己的东西”；用作动词时，意为“拥有；承 认”。

This is a picture of my own painting .

The three children grew up and had families of their own .

4 . remind 是及物动词，意为“使 ( 人 ) 想起”，后跟 of 引起的短语。例如：

I was reminded of my promise .

The photo reminds me of my school life .

The letter from my friend reminded me of our school days .

remind 还可以译为“使人想起；提醒”，后面可以跟带不定式的复合结构，或跟宾语从句。 例 如：

She reminded me that I hadn\'t watered the flowers .

Please remind me to hand in my composition tomorrow .

5 . wish 常可用来表示祝愿。例如：

I wish you a pleasant journey home .

I wish you success / luck / happiness / victory .

I wish you a happy birthday .

I wish you happy / lucky / well .

I wish you safe in the journey .

在英语中“wish + that - clause . ”表示“但愿……；希望……”，宾语从句用虚拟语气。 宾语从句如果和主句所表示的动作同时发生，从句的谓语动词用一般过去时；如果宾语从句所表 示的动作先于主句，从句中的谓语动词用过去完成时；如果宾语从句所表示的动作后于主句，从 句中的谓语动词用过去将来时。例如：

I wish I had your brain .

I wish I were taller .

I wish something interesting would happen very soon .

I wish you would forget it .

I wished that I had known what to say .

I with I hadn\'t said those terrible things about her .
