Recently I have started a new job in a small office，which four of us share a water filter（净水器）．One of my coworker complained the water tasted"dirty"，and she is astonished I could drink the water with any trouble．I even started to doubt my taste buds，but the water really tastes fine．Finally，she figured out the problem was actually my cup，which she simply forgot to clean．
I can't help but to think about the world we live in．Too often we quickly blame other people，other things，something else but ourselves．The world isn't perfect，I know，but I think we should take the step back sometimes and ask ourselves some tough questions．Can I be better？Is my heart really pure？…

Recently I have started a new job in a small office，which four of us share a water filter（净水器）．One of my coworker complained the water tasted"dirty"，and she is astonished I could drink the water with any trouble．I even started to doubt my taste buds，but the water really tasted fine．Finally，she figured out the problem was actually my cup，which she simply forgot to clean．I can't help but to think about the world we live∧．Too often we quickly blame other

people，other things，something else but ourselves．The world isn't perfect，I know，but I think we
                 anything
should take the step back sometimes and ask ourselves some tough questions．Can I be better？Is my
          a
heart really pure？…
Please clean your cup．Because when you do，the water will taste much good．I promise you this．
                                                          Better
解析：
1，which-where．考查定语从句的关系词．修饰先行词a small office，引导定语从句four of us share a water filter，做从句的地点状语用 where或in which．
2，Coworker-Coworkers．考查名词．One of 修饰可数名词的复数，所以用Coworkers．
3，is-was．考查时态．本段讲述的是过去发生的事，所以用过去式was．
4，with-without．考查单词辨析．本句表示"我喝水没有任何问题"，所以应该用without表示"没有"．
5，my-her．考查代词．从文中可知是她的杯子的问题，所以用her．
6，去掉to．考查固定句式．can't help but do 是固定用法，意思是"只能做"，所以去掉to．
7，live后加in．考查介词．定语从句we live修饰先行词the world，因为 live是不及物动词，所以要在live后加in或在world后加where．
，8，something-anything．考查不定代词．本句表示"除了我们自身的其他的任何事"，所以用anything．something表示"某一件事"．
9，the-a．考查冠词．本句表示"但我认为有时我们应该退一步"，表示"一"应该用不定冠词a．
10，good-better．考查比较级．用much修饰，表示"水比不洗杯子好喝"用better．
