答案：
4. A此处考查的是too...to...句型之一：
too＋adj.＋（a/an）＋n.＋to do / to be done
即：too后接一个形容词,然后接一个带不定冠词的名词（注意：不定冠词一定要放置于形容词后）,再接不定式（短语）.
使用时,注意以下事项：
只有当too后形容词修饰一个单数名词时,才可以在形容词与名词间加不定冠词a或者an.
当句子主语是该不定式的动作的执行者时,用不定式的主动式（即 to do)；当主语是该不定式动
作的承受者时,则用不定式的被动式（即to be done).
I have too difficult a math problem to work out.
It is too difficult a math problem to be worked out.
5. A首先,cheap的比较级为cheaper,而不是more cheap, 排除掉B和D；其次,这里由in the other shops可知含有比较的条件,但是要注意第二个空使用的是原级比较的 not as...as...结构,不过省略了as those in this shop罢了,所以要用原级good,排除C.
