问题补充：

The boy doesn speak his sister, but his written work is very good.

A. as well as

B. so good as

C. much better than

D. much worse than

答案：

(答案→)A. as well as

B. so good as

C. much better than

D. much worse than

解析：as well as和……一样，和……一样好；so good as用于否定句，和……一样好。much better than比……好多了；much worse than比……差多了。这个男孩说的不如他的姐姐好，但是他的书面表达非常好。本句中well用作副词，修饰speak，故选A。
