答案解析：
1． Dno more…than…“不比……更……”。此句意为：“研究表明，喝了酒但不过量的司机可能出车祸，不喝酒的司机也同样可能出车祸。”
2． Drather than起并列作用，使merciful与criminal形成平行结构，表示对比。
3． Anone but相当于no one but“只有”，通常接表示人的词；nothing but接表示物的词；none other than和no other than两者的意思都是“（不是别的）……正是……”，与本题全句意思不符。
4． Aas在句中是关系代词，引导非限定性定语从句，其先行词是precautions，其他几个选项都不是关系代词，所以是错误的。
5． Dwhat是关系代词，引导名词性从句，同时又在从句中充当一个成分，如在本句中做从句的主语，整个名词性从句做介词of的宾语；which只能引导形容词性从句；that引导名词性从句时，只是连词；whatever用在句中不通。
6． D时间状语thus far“到目前为止”，与现在完成时连用，据此排除B、C。比较从句完整的结构应该是…than the thought which has been given thus far，可以把than 看做关系代词在从句中做主语，也可以把主语看做是省略了。
7． A题句由于主语较长，采用了倒装结构，可还原为：the nation－wide movement to support the Kampuchean people in their heroic struggle against the aggression of the Vietnamese is of great significance。movement要求不定式做定语，其他选项均不符合语法规则。
8． Alooking for…分词短语做came的伴随状语，如果选to look for做目的状语的话，不该有逗号。
9． B动词request要求其主语从句、宾语从句或同位语从句中谓语动词用（should＋）原形表示虚拟。该句中that引导的是主语从句。
10． Dcant have done 表示对已发生的情况作否定推测“一定不是/没……”，根据句意只能选D。
