首先搞清楚upset的几种词性 动词 名词 形容词
而在这个句子里 表达的意思应该是 他走进教室,心烦意乱.
upset(心烦意乱的)在此是形容词用法 修饰he 表明状态

像B D其实都是含有一定时态意味的 在这个句子里没有这层含义
(并不是come这个动作伴随或导致的心烦 和动作本身无关 只是表现主语的状态)

B/表示当时进房间时的状态。
C、首先句子中有at this moment 表示进行的动作,这里的ing形式表示了铃声响时的伴随动作第一题答案选A那我错了呵呵嗯 第一题知道为什么选A吗 我还是看不懂如果是A的话,就是表示他过去某个时间进入房间时的状态,前面的came是动词的过去式,可能就不可以选B,因为B动词的ing也可以表示正在进行的动作,C不定式表示将来的动作,不符合 D是不定式的...
