30．A本题较难，可以用排除法。as在此题中既作连词，又充当后半分句中的成分。that不能用于“，”之后，so在题中不正确，it在句中两分句缺少连词，故选A

(五)

29．C本题较难，得认真分析句子的结构和成分。若将词序调整一下可能会更容易明白，“T0 people around，Einstein must have　　 to be mad'’，意为“对周围的人来说，爱因斯坦一定看上去是个疯子。”A、B、D都必须用被动的形式，故均错误，appear表示“看上去”，不能用被动。

28．B only too…to，just too…to，simply too…to等，后面的动词不定式不表否定意义。A、C两项不合题意，可排除；D项much不修饰一ad这样的普通形容词原级。

27．C　 整个句子前半部分为虚拟语气，与过去的动作相反，而后半部分but提醒我们动作是事实，所以用was。
