Question

英语，单选：() you come now,I'm going to leave without you. A Though B When C Until D Unless

英语，单选：() you come now,I'm going to leave without you.
A Though
B When
C Until
D Unless

Answer 1

选D
句子意为：除非你现在来，要不然我就不等你先走了。
其他单词代入，意义不对。

Unless 意思是除非，不然，用英语解释为if not
所以原句可以理解为
If you don't come now, I'm going to leave without you.
