1.___ are the days when teachers were looked down upon .A go

1. ___ are the days when teachers were looked down upon .
答案：B gone
解析：Gone are the days 是 the days are gone （时日已经流逝）的倒装句
2. I'll take no steps ___ you arrive .
答案：A until
解析：本句是 not...until 句型,也可以改写为 I won't take any steps until you arrive.(你来到以后我才采取措施)
3. It is the ability to do the job___ matters not where you came form or what you are .
答案：A that
解析：本句是强调句,即 the ability to do the job matters not where you came form or what you are （作工作的能力与你来自何方或你是谁没有关系）,主语 the ability 带有不定式后置定语 to do the job,这里强调的是主语部分,强调句的结构是：it + 被强调部分 + that + 其他部分.
4. ___terrible weather we've had these days.
____terrible the weather has been these days.
答案：第一空 A what,第二空 B how
解析：感叹句式其实是把被强调部分提前到句首,如果改为正常语序就可以一目了然：
1) We've had (what) terrible weather these days. 其中 terrible weater 整体是名词短语,用作动词 had 的宾语,what 是形容词性,修饰名词短语.
2) the weather has been（how）terrible these days.其中 terrible 用作系动词 be 的表语,说明天气的特征,how 是副词,修是形容词 terrible.
5. -- What do you think made Mary do upset?
--___ her new bicycle.
答案：A Lost
解析：
1）问句主体是 what made Mary do upset,用的是过去时态,其中 do you think 是插入语,征询对方现在对过去发生事情的看法.
2）答句是 She lost her new bicycle 的省略.
6. It is ___world of wonders, __ world where we can find anything changed.
答案：B a ,a
解析：第一个 world 带有描绘性定语,因此已经不是指那个独一无二的 world,而是一种奇迹般的 world（言外之意还有其他的 world）；第二个是第一个的同位语,对前者进行进一步的说明.
