two degree centigrade 中的degree要加“s”吗

首先，摄氏度一般不用centigrade，而用Celsius.
USAGE Celsius, rather than centigrade, is the standard accepted term when giving temperatures: use: 25° Celsius rather than | 25° centigrade .

然后，degree后面要加s因为degree是可数名词
eg. water boils at 100 degrees Celsius. (Symbol: °)

绝对没有

没有
