课文Has Ian sold his house yet?
伊恩已指他的房子卖掉了吗?
Yes,he has.
是的,卖掉了.
He sold it last week.
他上星期卖掉的.
课文第一句用的是现在完成时,可以用过去式表达吗?第三句为什么又要用一般过去式呢?另外不是说sold是瞬间动词不能用在过去完成时里吗?

改成过去式（仅仅从语法上看没有错误）：
did Ian sell his house?
yes,he did.
现在完成时的功能之一在于强调过去单一动作对现在产生影响,而一般过去时只是干巴巴的描述过去发生的短暂动作,强调对现在的影响还是要用现在完成时,而如何判断是否有影响,还要通过上下文语境来确定.
‘不是说sold是瞬间动词不能用在过去完成时里吗’楼主学习现在完成时只知其一,不知其二,完成时共有三种功能,上面提到的单一事件,这时候可以用短暂动词；重复事件,即过去的时间重复到现在；延续事件,过去的事件持续到现在；后两种用法我分别举例说明：
重复事件：i have met many new friends.
持续事件：i have been a english teacher for 3years.
对于持续事件这一用法,我们不可用短暂动词,短暂动词不能表示持续事件,举个错误例子：
i have married for 2 years.这里marry是短暂动词,不能和延续性时间状语 2 years连用；
如果改正,要么i have married.married 做动词表示过去对现在有影响的单一动作,第一种用法；要么 i have been married for 2 years.married 是形容词,be married 表示一种持续的状态,不是被动语态,这是第三种用法.
总结一下,短暂动词完全可以用于现在完成时态,但是不可以和延续性的时间状语连用,例如上句的2 years,而不是说短暂动词不能用于现在完成时.

课文Has Ian sold his house yet? Has Ian sold his house yet?中的 yet用法 has lan sold his house yet为什么要加yet Has Ian sold his house yet? 伊恩把它的房子卖了吗? No,he haven't. 还是 No 时态 CATHERINE :Has lan sold his house yet? 改错：Ian has sell his house. has lan sold his house yet ?他已经卖了房子了吗? Has Ian____(sell) his house yet? has he moved to his new house yet 变否定句 Has he moved to his new house yet 这句话的回答是什么? Ian sold his car (last week)针对打括号部分提问 She has sold the house she has/had?
