单项选择题
To have a computer without being connected to the Web is like having an old radio when everybody else has a color TV. That helps explain () businesses are setting up Net sites even though profits are nowhere to see.
A. reasons
B. the reason why
C. why that
D. why
答案
参考答案：D
解析：
[妙翻巧译] 拥有一台不联网的电脑就像别人有彩电，而你只有一台老收音机，这就是为什么很多公司都会建立网站，即使这样做无利可图。
此处需填一个连接副词来引导后面的从句，因为表原因，因为此用why；连接副词引导的名词从句前后不能再加that；所以D为答案。
