渗透语法

一、 though作副词，意为“尽管如此”、“然而”、“不过”。如：

She promised to phone. I heard nothing, though.

使用副词though时，要注意以下几个方面：

1. 作副词用的though往往位于句末（如上例），前面常有逗号，但有时也可不用逗号。如：

If you like sports that you can do on your own, then try dancing, shooting or aerobics (有氧运动). Some of these are very tiring, though.

He often makes mistakes. I don't think he is a foolish boy though.

2. 如果句子较长，though也可以置于句子中间。如：

There's no excuse, though, for hurting her feelings.

二、 though作连词，意为“虽然”。如：

Though we are poor, we are still happy.

使用连词though时，要注意以下几个方面：

1. though作连词引导让步状语从句时可以与although换用，只是 although 比 though 更为正式， 但作副词时却不可用although替代though。如：

Though / Although the work is hard, I enjoy it.

The work is hard; I enjoy it, though. (此句不可用although)

2. 不可在同一句中既用though又用but表示转折，二者只可选用其一。如：

他认为我太好说话了，不过也没关系。

He thinks I'm too easy-going, but it doesn't matter.

He thinks I'm too easy-going; it doesn't matter though.

三、 yet作副词用法。

1. yet作副词，意为“已经”、“至今”、“仍然”。 通常用于否定句和疑问句中及用于表示怀疑的动词之后，且通常位于句末。如：

Is your mother back yet?

I don't want to go away yet.

2. 副词yet有时与情态动词连用，意为“迟早”、“早晚”。如：

We may win yet.

四、 yet作连词用法。

1. yet作连词表转折，意为“但是”、“然而”。如：

He said he would be late, yet he arrived on time.

2. 连词yet有时可与并列连词and或but连用，构成习语and yet和but yet，且两者大致同义(均相当于表转折的but)｡

Everyone thinks that this is a simple method, but yet he can't believe it.

3. 连词yet不仅可以连接两个句子，也可以连接两个形容词，可译成“却”。如：

It is completely waterproof (防水的), yet light and comfortable.

4. although / though, while, even if不能与表示转折的but连用，但是可以与yet连用。如：

Although / Though we have made some progress, yet we still have a long way to go.

While they are my neighbors, yet I don't know them well.
