三道高中水平的英语问题第一问：the sharks have attacked a number of people 【off】 the beach of America,some of them a re seriously injured.我想请问这里的off是什么用法?是不是输入错误了?如果说是attack .off,那么后面的作为地点,应该充当地点状语,但是名词不可能直接充当状语.如果说这个off和后面的名词搭配作介词,构成地点状语的,那么请问这个off应该怎么理解呢?=第二问：they started off late and got to the airport with minutes to （spare/leave）答案是spare,因为网上说spare有剩余,多出的意思.但leave不是也有剩余,剩下的意思吗?为什么不能用呢?=第三问：Unlikey,they had a 【flat tire】 on the way back.flat和tire各自是什么意思?它们在此处各自的意

语法中,现在分词,过去分词作定语的用法!1-什么情况下分词不能与定语从句互换?我查到的例子中有这样一条规则：如主句谓语是现在时,从句谓语事过去时时.例如：The foreigner who visited our class yesterday is from Canada.(≠The foreigner visited our class yesterday is from Canada.)但是之后看的很多例句把这条推翻了,所以这条规则更详细一点说,是不是区别在延续性/非延续性动词上了?2-过去分词（不及物的）作定语表示完成,那么此时和现在分词的having done有什么区别?（除了having done不能作定语）,也就是说,过去分词表示的完成（have done）时态上怎么看?3很多语法书上写,特定的不及物动词可以有v-ed形式做定语,这个"特定"怎么定义?我怎么样就可以知道哪个可以哪个不可以?
