参考答案：
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"，atmost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tocarry省略。如果能判断出其省略部分，便很容易想到too…forsb.todo这个句型。
5.答案是D。通过信息句"Heleftaboutthreeweeksago."可判断出空白处强调的是时间
"不再"。nolonger常在句中强调时间，而nomore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.nomore与nolonger变为not…anymore或not…anylonger时，anymore或anylonger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,aswellas为同级比较，与否定词not连用，意为"不及……好"。
10.答案是A.angrilypointing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JohnplaysfootballaswellasDavid,ifhedoesn'tplaybetterthanDavid.
12.答案是A.从题干的"evenwhenthere'snotmuchtosay"这一信息句可知，空白处应为时间状语，而nowandthen正是时间状语，意为"有时"、"不时地"。
13.答案是A..bycar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rainhard/heavily.
16----20BDCCA
21.答案是B.关系副词where引导出一个定语从句，修饰thesmalltown.
22.答案是D.however是连接副词,引导出一个状语从句。
