基础英语同义词辫析：用英语说black和dark的区别
“黑色”的英语是black，但是，black的意思就不能是中文“黑色”了。Black的意思是英语！
Well, black is a color, just like red, blue,green.Black is a color just like a blackboard,or the ink we use for writing.
注意：black首先is a color, a color!
Dark也是a color吗？
“漆黑”的英语是dark，但是，dark的意思就不能是中文“漆黑”了。Dark的意思是英语！
What is dark?
Well, dark is not a color like black.
Dark, or darkness is when our eyes can not see anything at all just like the night time.
Why? Because there is no light from a lamp, or from the sun(visibility is low 能见度很低。这个表达有点难度，但很有用：low visibility means no light or not enough light)
这才是dark,or darkness.
So dark is our eyes can not see anything, darkness is because there is no light!
Black is a color.Dark is we can not see.
这就是black和dark的区别。
我们用英语区别它们，同时“说英语口语”。
