• 平滑肌与横纹肌做功有什么区别?费曼曾经说过一个题目：一个人提着一桶水站着,他对这桶水做功吗?看上去他没有在力的作用方向上移动,this is true.但是他还是会累,还是会出汗.事实上,他是做功的.这里面就是一个平滑肌和横纹肌的区别.平滑肌做功的时候实际上是在“无穷动”,你并没有不动,实际上你一直在力的作用方向上做微小的“抬升,放下”的动作,当你累得发抖的时候就可以很清楚地看到这点.但是如果你用一卷肠子把这桶水吊起来,肠子的肌肉确实是不做功的,因为平滑肌可以“卡死”,而横纹肌不能.这很大程度上解释了这个问题,但是我对这种区别的机理还不是不大清楚,crocodilepy：定义我知道啊。你学过生理学吧

• 关于现在分词的完成式现在分词的被动形式:being+动词过去分词 现在分词的完成形式:having+动词过去分词 现在分词完成式的被动式:having been+动词过去分词这样我就想问几个问题.首先现在分词的完成形式与Have/has+动词过去分词有什么区别?能不能给个例句对比下(最好有中文翻译)还有Having been shown around the school, we had a rest.这句话我想用的应该是现在分词完成式的被动式.是以前发生的.既然是以前发生的为什么要用现在分词的完成式?也就是为什么要用having.其实我关键就是不明白.现在分词的完成式到底是怎么回事.因为我是这么想的.现在分词一般都是现在正在进行的.而完成是过去..这两个放一起.很晕!~希望有人能给我解释下哈,谢谢大家~kj918能把英文例句加上汉语翻译吗...好多都看不太明白的.....
• 老师有讲,在陈述句中含有have时,如果have是实义动词,附加问句就用do的适当形式,如果have是时态助动词时,附加问句就用have相对应的时态的形式.如讲义中的：“You had a class meeting yesterday,didn't you?”,在此句中had是have的过去式,且是实义动词,意为“拥有、有”,这个很好理解.had反义疑问句用法反义疑问句中陈述句含有have,附加问句的用法.问题类型：录音讲座 老师有讲,在陈述句中 但讲义中的另一句我不理解：“He hasn't any money,has he?“,在此句中,我觉得has是have的第三人称单数,是实义动词,意为“拥有、有”,但为什么附加问句不用does he?而用has he?
