两道完型填空
No one knows how man learned to make words. Somehow he learned to make them. _1_ the centuries went by, he made more and more words.
...
people living in different countries made different kinds of _2_.
1.A. When B. As C. While D. With
2.A. language B. dictionaries C. tools D. words
答案是B和D,我想知道别的为什么不对

1.as 有伴随的意思,虽然WHEN,WHILE也可以用上,意思为"当...时候",不过很明显,同"他创造了越来越多的词语"不搭调.WITH 就不说了,是要跟动词或动名词的;
2.这里的WORDS是在照应前面,上文提到过的.

1.B
2.A

1,as表示随着,是一个固定用法
2,words是、因为上面No one knows how man learned to make words.
