四、频度副词

1. 频度副词的特点

频度副词表示动作发生的次数,常见有的ever, never, rarely, seldom, once, often, occasionally, constantly, frequently, usually, continually, always 等。

2. 频度副词在句中的位置

频度副词通常位于实意动词之前,动词be、助动词、情态动词之后:

He often comes to see us. 他常来看我们。

He is seldom late for school. 他上学很少迟到。

有时为了强调,频度副词也可位于动词be、助动词等之前:

She always was late. 她老是迟到。

有的频度副词可位于句末(尤其受very, only修饰时):

I get paid on Fridays usually. 我通常在星期五领工资。

We go out very seldom. 我们很少外出。

Do you go to the cinema very often? 你常去看电影吗?

有的频度副词(如sometimes, often, usually, frequently, occasionally等)可位于句首(此时多半是因为强调或对比):

Sometimes he went there by bus. 有时他坐公共汽车去那儿。

Very often the phone rings when I’m in the bath. 电话经常在我洗澡时响。

【注】含有否定意义的频度副词置于句首时,其后要用倒装语序:

Never have I been there. 我从未去过那儿。

Seldom does he see a film. 他很少看电影。

另外,频度副词always 和 never通常不位于句首,除非是祈使句:

Always remember this. 时刻记住这一点。

Never go out at night. 晚上千万不要出去。

3. 频度副词在否定句中的位置

在否定句中,有的频度副词可位于否定词not之后或之前(如usually, often),有的频度副词则必须位于否定词之后(如always, constantly, continually, continuously,均含有“连续不断”之意),而有的频度副词却必须要位于否定词not之前(如sometimes, frequently):

He doesn’t usually come here. / He usually doesn’t come here. 他通常不来这儿。

She doesn’t always come late. 她并非总是迟到。(不能说 always doesn’t)

He is sometimes not responsible for what he does. 他有时对所做的事不负责任。

五、程度副词

1. 程度副词的特点

程度副词用于表示程度,常见的有 fairly, pretty, rather, quite, very, much, too, greatly, almost, nearly, half, highly, awfully, deeply, partly, perfectly, really 等。

2. 程度副词的用法注意点

(1) 程度副词主要用于修饰形容词和副词,有的还可修饰比较级(如much, rather 等)和最高级(如quite, much, almost 等):

Houses are much more expensive these days. 如今的房价贵多了。

This is quite [much] the most expensive radio here. 这是这里最贵的收音机。

【注】quite 有时也修饰比较级,但只用于quite better(身体康复)这一表达。

(2) 有的程度副词(如quite, rather, almost等)可修饰动词,但有的(如fairly, pretty, very等)则不能修饰动词:

I quite agree with you. 我完全同意你的意见。(不用fairly, pretty, very)

We rather like the film. 我们很喜欢这部电影。(不用fairly, pretty, very)

(3) 个别的程度副词(主要是quite和rather)还可修饰名词(注意词序):

It’s quite [rather] a good idea. / It’s a quite [rather] good idea. 那可真是个好主意。

若此结构中没有形容词,则 quite 和 rather 则只能放在冠词之前:

It was quite [rather] a success. 那事相当成功。

六、连接副词

1. 连接副词的分类

连接副词可分为两类,一类是用于连接句子或从句,常见的有therefore, besides, otherwise, however, moreover, still, thus, meanwhile等;另一类是用于引导从句或不定式,主要的有when, why, where, how 等。

2. 连接句子或从句的连接副词

其性质类似于并列连词,使用时其前通常用分号或句号;若其前用逗号,则通常带有并列连词(如and):

I don’t like it; besides, it’s too expensive. 我不喜欢它,而且也太贵了。

We all tried our best; however, we lost the game. / We all tried our best. However, we lost the game. 我们都已尽了最大的努力,不过我们还是输了。

注意,有的连接副词(如however等)后通常有逗号与句子的其他成分隔开。另外,这类副词有的还可位于句中或句末:

He may, however, come later. 不过,他也许一会儿就到。

We all tried out best. We lost the game, however. 我们都已尽了最大的努力,不过我们还是输了。

Peter is our youngest child, and we have three others besides. 彼特是我们最小的孩子,我们另外还有三个。

3. 引导从句和不定式的连接副词

用于引导从句(名词性从句)或不定式的连接副词主要有when, why, where, how等:

Tell me when we shall leave. / Tell me when to leave. 告诉我什么时候离开。

I don’t know how I can find him. / I don’t know how to find him. 我不知道如何找到他。

Where we can get the money is just our problem. / Where to get the money is just our problem. 到哪里去弄这笔钱正是我们头痛的事。

That’s why he speaks English so well. 那就是他为什么英语讲得这么好的原因。

【注】连接副词why 后不能接不定式,如可说 I don’t know why I must leave.(我不知道我为什么必须离开),但不能说 I don’t know why to leave。
