B  考察非谓语动词,过去分词做后置定语,known only to people with specific knowledge修饰前面出现的words,expressions or phrases,动词know与被修饰名词为被动关系,因此用过去分词,表示“被动,不计较时间”,一般描述理论的句子或描述常态的句子都直接选过去分词.
A选项也是被动,但它表示“与谓语同时发生”,C被动,表示“后于谓语发生”,D被动,表示“先于谓语发生”,一般不做后置定语,即使做,也要做成非限制性定于形式.

C  expose需要用被动形式,be exposed to,因此B不对.此句缺主语,A过去分词不能做主语,D是状语,C现在分词可做主语.

D  put away表示“储存”,在高中还有一个意思经常考,就是“收拾好”,可表示具体的,也可表示抽象的,“收拾好东西”和“收拾好情绪/整理情绪”.

B  表示“除了……之外,还有……”,A与B是一个意思,但是A缺少介词,应该是in addition to；C与D表示“除了……之外”.

D  考察非谓语动词的动词不定式,被动意义用主动形式表达,blame与let（出租）在动词不定式作表语时,都用主动的.

D  第一空考察非谓语动词的过去分词做后置定语,理论与题1一样；由于只有D选项的第一空正确,第二空就不用解释了.A 选项的第一空虽然也是非谓语,也表示被动,但它是“后与谓语发生”的意思,题意不对.B与C的第一空都是谓语,简单句中不能用两个谓语.

C  考察虚拟语气,if only条件状语从句必须虚拟,采用倒退时态的原则,根据上文,可推测出是“过去没有听取你的建议”,因此是对过去的虚拟,倒退称过去完成时.

1. B.我理解的是Don‘t use ... (which were) known only to ...，修饰前面的words 等等，整句话就是说不要使用只有知道某种特定语言的人才明白的单词，表达式或者短语。

2. C。be exposed to ,现在分词组成的主语从句。整句话是说暴露在太阳底下太长时间有损皮肤。

3. D。这是...

   1. B.我理解的是Don‘t use ... (which were) known only to ...，修饰前面的words 等等，整句话就是说不要使用只有知道某种特定语言的人才明白的单词，表达式或者短语。

   2. C。be exposed to ,现在分词组成的主语从句。整句话是说暴露在太阳底下太长时间有损皮肤。

   3. D。这是对短语的了解考察，整句话的大概意思是说为老年存一些钱是明智的。所以选择put away，存储钱。have some money put away ,存一些钱，语法结构和 have ears pieced ,穿耳洞一样。

   4. B。in additon to +n,除此之外，这有apart from 有除了...之外，还有的意思；通俗的说，就是except连接的两方是相减的关系，而apart from 连接的两方是加的关系。

   5. D。 be to blame ，受到谴责，对什么负责，固定用语。

   6. D。（which was）put foward by Einstein，做为定语从句修饰the theory

   7. C。虚拟语气，if only...：如果。。。该有多好啊；从句子的意思上知道是过去式的虚拟语气，所以使用过去完成时。

   以上是我的理解，如有错漏，望见谅
