首先,Mr.White works with a chemicals import& export company,but he is working for this industrial fair,since he is on leave.选D表示这段时间他的状态,全句可以这样理尽管怀特先生现在正在同一家化工进出口厂合作,但是他只是为这次的工业展会工作,因为他现在正在休假.大概可以这样理解他在这个展会工作是兼职性质的,也是他休假阶段正在做的事情.
第二题,前面一句,强调句It was a physician that he represented himself,相信意思你也知道,我就不解释了；and as such he was warmly received,such指代前面一句,本来选 so that意思也没什么不对,但是有and,连接词重复.可以这样表述：he was a famous musician so that he was warmly received.哇~~解释得好~醍醐灌顶的感觉~~还有第三个~~嘻嘻刚写好~嘿嘿第三题，The budget is unrealistic in that it disregards increased costs.相信句子意思你也是理解的，in that是固定搭配，意思就是”because”.而for that应该这样用：The reason for…is that.不明白的可以继续追问~~那是不是用for表示原因的时候后面只能跟动名词啊其实for表原因一般会和reason连用，后接动名词或名词，一般是不跟句子的，至少我还没遇到过。恩，就是这样
