　　1．【答案】A
　　【解析】根据句子结构可以判断出town后面为定语从句。定语从句中关系词的选择取决于该词在从句中的句法作用。该定语从句既不缺主语，也不缺宾语．故不需要关系代词，B项和D项可以排除。C项中虽是”介词+关系代词”结构．但是介词on用的不合适。where在定语从句中作状语，因此只有A项既符合语法，又符合结构，为正确答案。
　　2．【答案】C
　　【解析】on用来指时间，表示”在……之时”，相当于at the same time of，后跟动名词或表示动作的名词，例如：On his arrival in Qingdao，he set to work in earnest．一到青岛他就认真地干了起来。而at，with和during则没有这种用法。
　　3．【答案】C
　　【解析】根据句子结构．我们可以将B项和D项排除。A项中 the fourth biggest city 与主句中的the 24th biggest city相矛盾。正确答案为C项。Once在这里作连词，引导一个省略了主语和be形式的谓语。例如：Love，like Reputation，once fled，never returns. 爱情像名誉，一旦失去，永不再来。Love is like a mirror：once broken, that ends it. 爱情就像一面镜子：一旦破碎，断难重圆。
　　4．【答案】C
　　【解析】expect为及物动词，作”期待，预期，盼望”讲，可以构成expect sb. (sth．)或”expect sb．to do sth．”或”expect that+从句”。后接复合宾语时，宾语补足语一般要用带to的动词不定式。A项中的for多余，B项中的宾语补足语没带to，D项中不定式被动形式的使用将one和change由原来的逻辑主谓关系变为逻辑上的动宾关系，改变了题意，因而A项、B项和D项错误，只有C项为正确答案。
　　5．【答案】A
　　【解析】代词one和that都可以用来指代前文出现的名词，其区别在于：that代替前面有定冠词的名词或不带冠词的名词，而one代替前面有不定冠词的名词；one只能代替普通的可数名词，不可用来代替不可数名词；而that可用来代替不可数名词，that的复数形式为those；而one的复数形式则为ones：This is a point of idiom rather than one of grammar．这是一个成语问题而不是语法问题。The cost of oil is less than that of gas. 油的价钱比煤气的价钱低。The population of Shanghai is larger than that of Xi’an．上海的人口比西安多。因此A项正确。it代替所指清楚的物。例如：Give it to me，please．请把那个给我(听者知道”it”指什么)。D项what不能代替前面出现的名词，因此D项错误
