特殊疑问句意思是：你什么时候种植过这么多的树的?这句句子是现在完成时
特殊疑问句
以疑问词开头,对句中某一成分提问的句子叫特殊疑问句.常用的疑问词有：what who whose which when where how why等.
可先分为3种:
疑问代词：what,who,Which,whose,whom
疑问副词：when,where,why,how
疑问形容词：what（which,whose）+名词
特殊疑问句有两种语序：
1．如疑问词作主语或主语的定语,即对主语或主语的定语提问,其语序是陈述句的语序：疑问词（＋主语）＋谓语动词＋其他成分?如：
who is singing in the room?
whose bike is broken?
2．如疑问词作其他成分,即对其他成分提问,其语序是：疑问词＋一般疑问句语序?如：
what class are you in?
What does she look like?
Where are you from?
What time does he get up every morning?
How do you know?
注意：
1．回答特殊疑问句时,不能用yes ／ no,即问什么答什么,尤其是简略回答.如：
Who is from Canada?
Helen (is)．
Where's the restaurant?
Near the station．
Why do you like koalas?
Because they are cute．
2．特殊疑问句一般读降调(↓).
特殊疑问词
Who谁——Whose谁的
Why为什么 When什么时候 Where在哪里 Which哪一个
What什么 ( What time什么时间 What colour什么颜色）
How怎么样（How many多少{数量} How much多少钱{价格} How long多长 How often多少次 How big多大 How heavy多重{重量}How far多远{路程}

Since是一个有很多用法的词语。。。可以表示因为的意思，不仅仅局限于“自从”。。
所以这还是个比较普通的特殊疑问句。。。。。。。
