米厚，这说明他们可能整个冬季都在烧火。
? have?been?excavating 现在完成进行时
表示从过去开始一直延续到现在，或
将继续延续至将来。?现在完成时和现在完成进行时的区别：
现在完成时表示已经完成，而现在完成进行时表示还没完成还要延续下去或者刚刚完成。如：?
They?have?built?a?house.?(完成)??
They?have?been?building?a?house.?(尚未完成)4.?Our?evidence?suggests?they?did?indeed?

? suggest最常用有两个意思：
? 1) 提议；提出；建议，后接动词要用动词的ing形式，后接宾语从句时，从句用虚拟语气(“should+动词原形”，should常省略)。后接宾语从句要用虚拟语气的词可记为：一个坚持：insist??
二个命令：command,?order??
四个建议: advise,?suggest,?recommend,?propose
四个要求：ask,?demand,?request,?require?
2) 表明，显示，暗示；显出，后接宾语从句(不用虚拟语气)。表示动作从过去某一时间开始一直延续到现在，动作可能刚刚停止，也可能还在进行。常与for或since所引导的短语或从句连用，也可与all this time, this week, this month, all night, all the morning, recently等时间状语连用。构成：肯定形式为“have / has + been +动词-ing形式”，否定形式为“haven’t / hasn’t + been +动词-ing形式”。如：语法现在完成进行时You know, I have been looking for a job for three months, and this is my first formal interview.
Since returning home from studying abroad, he has been working in this bank.
I’ve been writing letters all this evening and I’ve just finished them.
According to your teacher, you haven’t been doing your homework these days.【拓展】
现在完成进行时与现在完成时相比，主要有三个特点：
1. 未完结性。现在完成时表示动作已完成，而
现在完成进行时则常常具有未完成含义。
2. 短暂性。现在完成时与现在完成进行时都可
表示延续至今的状态，但是现在完成进行时
常常表示短暂性。如：
They have lived in New York.?（长期性）
They have been living in New York.（短暂
性）3. 连续性或重复性。现在完成进行时常常
用于表示延续至今的连续性或重复性动
作。如：

物品介绍类说明文写作应注意以下几点：
1. 抓住特征、说明到位。
要把一件物品展现在读者眼前，给读者一种“虽不见其物，却犹见其貌”的效果，因此抓住事物的特征，这一事物区别于其它事物的标志，显得尤为重要。只有抓住事物的特点，才能给读者留下深刻的印象。2. 层次分明、条理清晰、内容连贯。
采用恰当的说明顺序。写作时要根据说明对象的特征来合理安排写作顺序，从物品的外观、构造、功能等方面来分层描述，做到层次分明、条理清晰、内容连贯。
3. 表现手法多样。
采用举例、列数字、作比较等不同说明方式，让读者更好地了解所介绍的物品。
4. 语言简明、贴切。
语言要通俗、简洁、准确。【常用表达】
It looks like ...
It may be used as / for ...
It is made from / of ...
It is ... meters high / long, with ... on its top.
It is as big / high as ...?【实战演练】
