某检修小组乘一辆汽车沿公路检修线路,约定向西走为正,某天从某地出发到收工时,行走记录为+8,-5,+6,+3,-9,+11,-1,+7,-2,+5（长度单位：千米）：
（1）收工时,据出发地多远
（2）若汽车每千米的耗油为0.1升,求从出发到收工共耗油多少升?

Answer 1

一般疑问句：
1）对于助动词、情态动词、be动词作谓语的,掉换主谓.如：
He's a teacher.
Is he a teacher?
He can swim.
Can he swim?
He'd like to go there.
Would he like to go there?
2）对于实意动词作谓语的,动词原型借助do,三人称单数借助does,过去式借助did,加在句首,再把谓语改为动词原型.如：
I like him.
Do I like him?
He likes me.
Does he like me?
I liked him.
Did I like him?
特殊疑问句：
先改一般疑问句,去掉要提问的成分,再在句首加相应疑问词.如：
I will go there by bus.（就 by bus 提问）
先改：
Will I go there by bus?
再改：
How will I go there?
