问题: 这几个or怎么辨析？
In which of the sentence the word “or”differs in meaning from those in the rest?
A.The Earth is shaped like a sphere,or a ball
B.The moon has no air or water
C.There are holes,or craters,all over the Moon's surface.
D.That's bacuase the Earth rotates, or turns around,every 24hours.
答案给的B,怎么辨析？
解答:
B.这句话里的or表示两者都没有,其它的都是表示另一种说法.试着用"also known as"代入上面四句,只有B是说不通的.
