2）连接副词：

连接副词意思和词形都和疑问副词一样，但都引导从句或与不定式连用：

how: That’s how I look at it. 这是我的看法。（引导表语从句）

     Do you know how to start this machine? 你知道这台机器怎样启动吗？（引导不定式短语）

where: I don’t know where he lives. 我不知道他住在哪儿。（引导宾语从句）

      I can’t decide where to go for my holidays. 我不能决定去哪度假。（引导不定式短语）

when: Tell me when you’ll be ready. 告诉我你什么时候准备好。（引导宾语从句）

     Tell me when to use this construction. 告诉我什么时候用这种结构。（引导不定式短语）

why: That’s why I came round. 这就是我来的原因。（引导表语从句）

3）关系副词：

关系副词可引导关系从句作宾语：

where：We then moved to Paris, where we lived for 6 years. 此后我们搬到巴黎，在那里住了6年。

when: There came a day when the rain fell in torrents. 有一天下起了倾盆大雨。

why: The reason why he came is not very convincing. 他来的理由不太有说服力。

6.句子副词

1) 有些副词并不修饰动词，而是修饰整个句子，表示说话人的看法：

I can’t come, unfortunately. 真不巧，我来不了。

Hopefully We’ll win. 但愿我们能赢。

Surprisingly, she has married again. 另人惊讶的是，她又结婚了。

Seriously now, you ought to take more care of your health. 说真的，你应当多注意身体。

2）有少数副词可以和enough连用，起同样的作用：
I thought it would rain, and sure enough it did. 我想天会下雨，结果果然如此。
Oddly enough I had no doubt that he would be glad to see me. 说也奇怪，我毫不怀疑他会高兴见我。
Curiously enough he had never seen the little girl. 说也奇怪，他从未见过这个小姑娘。
6. 一些其它类型的副词
除了以上这些类型的副词外，还有一些其他类型的副词，例如：
1）表示方向的副词：
Let’s go inside. 咱们到里面去。
Take two steps forward. 向前走两步。
2）使与上文连接更紧的副词：
He was different, however, from the others. 不过他和别人不同。

3）表示 “方面”的副词：

    Financially we are doing quite well. 在经济方面我们情况良好。
    It’s politically short-sighted not to recognize this. 不认识这一点在政治上是短视的。
三、副词的位置
1. 副词修饰动词时，通常可以放在句首、句中或句末。如：
    Usually I do my homework in the evening. (句首) 通常我晚上做家庭作业。
    I often get up at six. (句中) 我常在6点起床。
    Please speak slowly. (句末) 请慢慢说。
2. 副词修饰形容词或副词时，通常放在形容词或副词的前面，但也有例外。如：

    He works very hard. （在副词前）他工作很努力。
    She is old enough to go to school. （在形容词后）她已到了上学的年龄。
3. 按一般规则，如果有几个时间状语，单位大的应放在单位小的后面。如：
    The film will begin at seven o’clock this evening. 电影今晚7点开演。
    I was born at two o’clock on the morning of May15.
4. 按一般规则, 既有地点状语又有时间状语时，地点状语应放在时间状语之前。如：

    He watched TV at home last night. 他昨晚在家看电视。
四、副词的比较级和最高级
1. 副词的比较级和最高级的构成
     副词和形容词一样，也有原级、比较级和最高级三个等级。其构成方式有规则变化和  
不规则变化两种情况。规则变化的一般规律是：单音节词的比较级和最高级在词尾加-er或
-est; 多音节词以及-ly结尾的副词（early除外），前面须加more 或most. 不规则的变化式
只能采用“各个击破”的办法去记忆。

1）规则变化

原级	比较级	最高级
soon long loud fast wide early happily carefully	sooner longer louder faster wider earlier more happily more carefully	soonest longest loudest fastest widest earliest most happily most carefully

2）不规则变化

原级	比较级	最高级
well badly little much far	better worse less more farther further	best worst least most farthest furthest

答案与解析（部分）
1. 答案是D. 同级比较的结构为 “as+ 副词原形+ as”.
2. 答案是C. almost 意为 “几乎”、“差不多”，at most 意为 “至多”， 均与语意不合。most 意为“多数的”，mostly是副词，意为“主要地”、“大部分地”。
3. 答案是C. 答题的关键是要知道grain 为不可数名词。
4. 答案是D. 本题考查对基本句型的掌握。从表面上看，4个选项似乎都可以修饰形容词，而且从上下文中也很难找到提示。其实，命题者有意将题中to carry省略。如果能判断出其省略部分，便很容易想到too…for sb. to do 这个句型。
5. 答案是D。通过信息句“He left about three weeks ago.” 可判断出空白处强调的是时间
“不再”。 no longer 常在句中强调时间，而no more 常强调数量和次数。

6. 答案是C. 表示倍数的词或其他程度副词作修饰语应放在as…as结构的前面。
7. 答案是D. no more与no longer 变为 not …any more 或not…any longer时，any more或any longer 要放在谓语动词后。
8. 答案是C。long 指一段时间，不能与终止性动词finish 连用；often指时间频度，即每隔一段时间发生一次动作；rapid 是形容词不能修饰动词。
9. 答案是A. 用 well修饰speak, as well as 为同级比较，与否定词not 连用，意为“不及……好”。
10. 答案是A. angrily pointing 为分词作状语，表示伴随情况。还应注意副词的位置。
11. 答案是B. 这是同级比较，全句可理解为John plays football as well as David, if he doesn’t play better than David.
12. 答案是A. 从题干的 “even when there’s not much to say” 这一信息句可知，空白处应为时间状语，而 now and then 正是时间状语，意为 “有时”、“不时地”。
13. 答案是A.. by car 是方式状语，所以疑问副词应是how.
14. 答案是C. however 是连接副词，修饰形容词great并引导出一个状语从句。
15. 答案是D.“下大雨”应说 rain hard/heavily.
16----20 BDCCA
21. 答案是B. 关系副词where 引导出一个定语从句，修饰the small town.
22. 答案是D. however 是连接副词,引导出一个状语从句。
