为什么 when后可以省略“you are”

Answer 1

正确答案：B.
本题考查短语【leave sb doing sth 】和状语从句中的省略.
手机没电的时候,你是被留在那儿和自己说话,所以用被动形式.此处状语从句中省略了【you are】.补充完整为：
when【you are left talking】to yourself after you mobile phone battery runs out in the middle of a call.
温馨提示：
状语从句中的省略有两个条件：
1）谓语动词必须含be动词（is、am、 are、was、 were）；
2）从句主语与主句主语相同或者从句主语为it.
例如：I won't go unless invited.= I won't go unless 【I am】invited.
Fill in the blanks with articles where necessary.
= Fill in the blanks with articles where 【it is】necessary.
