问题 Young scientists cannot realize______ soon that existing scientific knowledge is not nearly so complete, certain and unalterable as many textbooks seems to imply.
选项 A、so
B、very
C、too
D、such
答案C
解析 此题考查副词的用法，such 不能用作副词，不能用来修饰形容词，应首先排除。再根据题意判断that从句是realize的宾语从句，由此可排除so。very不符合题意。本句意为：年轻的科学家还没有认识到现有的科学技术并不像教科书中描述的那样完善、肯定和一成不变。
