第10题：

His presentation will show you ____ can be used in other contexts.

A. that you have observed
B. that how you have observed
C. how that you have observed
D. how what you have observed

答案：D
解析：
考查从句。show sb sth结构，这里sth是how引导的宾语从句，宾语从句中缺主语，what引导的主语从句，翻译为“所??的”what作observe的宾语。句意为“他的发言将向你展示，你所观察到的如何被用于其他语境”。所以正确答案为D。
