30．A本題較難，可以用排除法。as在此題中既作連詞，又充當后半分句中的成分。that不能用于“，”之后，so在題中不正確，it在句中兩分句缺少連詞，故選A

(五)

29．C本題較難，得認真分析句子的結構和成分。若將詞序調整一下可能會更容易明白，“T0 people around，Einstein must have　　 to be mad'’，意為“對周圍的人來說，愛因斯坦一定看上去是個瘋子。”A、B、D都必須用被動的形式，故均錯誤，appear表示“看上去”，不能用被動。

28．B only too…to，just too…to，simply too…to等，后面的動詞不定式不表否定意義。A、C兩項不合題意，可排除；D項much不修飾一ad這樣的普通形容詞原級。

27．C　 整個句子前半部分為虛擬語氣，與過去的動作相反，而后半部分but提醒我們動作是事實，所以用was。
