1.HOW DO YOU DEAL WITH THE DISAGREEMENT THE COMPANY AND THE CUSTOMERS?THE KEY( )THE PROBLEM IS TO MEET THE DEMAND( )BY THE CUSTOMERS.
A.TO SOLVING;MAKING B.TO SOLVING;MADE C.TO SOLVE;MAKING D.TO SOLVE;MADE
B. key 后面的to是介词，须跟动名词，demand是被顾客提出来的，要用被动式，过去分词made表被动。
不要听前面瞎说，这个题就考你对to的判断。它不是不定式符号，而是介词，例如：the key to the questions问题的答案。绝对不可以在这个to后用动词原形。

2.DON'T USE WORDS,EXPRESSIONS,OR PHRASES( )ONLY TO PEOPLE WITH SPECIFIC KNOWLEDGE.
A.BEING KNOWN B.HAVING BEEN KNOWN C.TO BE KNOWN D.KNOWN
D。 known过去分词表被动。只有具有专业知识的人才可以懂得的单词，短语。动词不定式作定语一般用主动式表被动。所以不宜选C。
二楼说的也对，但不是省略了which are，这是两种表达法，一种是过去分词作定语，一种是定语从句作定语。

1.D
第二个不清楚了。。。

1，B the key to这个to是介词，后面只能加ing
后面意见是被客人提的，要用被动，made by
2，D 被人们知道的，被动，本来是which are known ONLY TO PEOPLE WITH SPECIFIC KNOWLEDGE. 省略了 which are

1：B
the key to （doing）sth.做什么的关键在于......
第2个空是顾客提出的要求，所以DEMAND后要用被动语态MADE
2：D
不要用那些只有具有专业的知识的人才懂的词语短语...
同样是被动语态，选KNOWN
