• 先行词是the way,place,time,reason关系副、代词何时可省?为什么这句要加where:We've all used thermometers to measure temperature but sometimes we need to measure temperature in places WHERE you can't put a thermometer.语法说,先行词是the way,表示方式,可用that（可省）或in which来引导一个定语从句.如果先行词是时 间或原因,也可用that（可省）或when或why来引导定语从句.如：（1）This was the reason that/why he was late yesterday.（2）This is the last time that I shall give you a lesson.这句是道改错题,还要加上where 是什么原因?没表达清楚，我的意思是that代替关系副词，那么我这道改错题为何还要加
• 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?

• 英语语法疑问It is high time +一般过去时,作为虚拟语气.那么,it was high time 后面用一般过去时还是过去完成时?It was the training that he had as a young man () made him such a good engineer.A hasB laterC thatD which我选B.因为这是强调句型,如果不强调：The training he had as a young man made him such a good engineer已经是一个完整的句子了,所以,不应该用连词that或which来引导.为什么?我忽然明白了，应该选C that这个C才是和前面的it was组成强调句型。前面的that引导的是定语从句。另外，我前面的那个问题：it was high time that 后面动词应该怎么用？用什么时态？
