Question

Many people are not fully aware of the damage that it does to their health. This is ____ we chose this picture as our logo.

A．that	B．because
C．why	D．for which

Answer 1

C

試題分析:句意：許多人沒有充分意識到它對健康的損害。這就是我們為什么要選擇這張圖片作為我們的徽標。Is后面是表語從句，根據前后句意可知此處表示結果，固定句型：this is why+從句“這就是為什么……”，this is because+從句“這是因為……”，答案選C。
