Ⅰ.单句语法填空
1．Sometimes it's hard to accept the truth ________ the lie sounds so much better.
because [句意：有时候事实真相很难被接受，因为谎言往往要顺耳多了。此处表示原因，故填because。]
2．________ noted otherwise, these brochures are free of charge.
Unless [句意：除非另外说明，否则这些小册子都是免费的。根据语意可知，空格处用unless，引导一个省略的状语从句，相当于Unless they are noted。]

before [句意：她是个非常骄傲的人，宁愿死也不认错。这里用before，翻译成“宁可……也不愿”，常与will或would连用。]
4．I had hardly rung the bell ________ the door was opened suddenly, and my son rushed out to greet me.
when [句意：我刚一(几乎还没有)按门铃，门突然就被打开了，我儿子就冲出来迎接我。hardly/scarcely ... when，表示“一……就，刚刚……就”。]
