今天的翻译题是：

1.___________(我本该将此事告诉他)，but I was so focused on my experiment that I forgot.

2.These people did nothing _______________(除了整日在街上闲逛),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。
