今天的翻译题是：
1.___________，but I was so focused on my experiment that I forgot.
2.These people did nothing _______________,which causes a lot of concern.
答案解析:
1.答案:I should have told him about this//I ought to have informed him of this
详解:
考查虚拟语气:此处but引导的虚拟语气属暗含的虚拟语气，前一部分是虚拟语气，后一部分是陈述语气。由于后部分是过去式的陈述句，故前半句的虚拟语气用完成时态，表示过去未做之事，用should/ought to have+过去分词结构。
考查固定搭配:将告诉的表达是tell sb. about sth.或inform sb.of sth.。
2.答案:except/but hang around on/in the street all day long
详解:
考查介词:除了的表达是except或but,do nothing but/except后面用动词原形。But用于nobody，nothing,no one,all等词后面表示除以外。
考查词组:闲逛译作hang around;整日的表达是all day long。
