6物以稀（in short supply）为贵
7B.考点：in that 复合连词引导原因状语从句,表示“在于”.
8D
分析句子成分后发现,visit为及物动词,所缺部分为宾语,所以应该选择关系代词.因为这里涉及到了最高级,所以只能选that.
9C
个句子成分还挺多的,第一层就是主要的“why do you blame him when ...”就是当他需要的是鼓励的时候,为什么要责骂他?
“for his poor judgment on the matter”是对前面“why do you blame him”做的补充,算一个原因吧.
最后就是when后面的“what he really needs is encouragement”这是由what引导的同位语从句,what其实就是指的encouragement,所以when what不是合在一起组成词组哈,而是“当他最需要的是...”由when引导的条件从句里又含有what引导的同位语从句
10 B 不知所措
11 likely be likely to do sth
12Bbe done
It is vital ...从句用should+动词原型（有时可省略should）的虚拟语气
13D
be left...：被置于...的境地.它是leave sth...的被动式.standing：站立的,固定的,直立的.be left加形容词是常用的一种表达方式
14B
be persistent in doing something
15A
A .“公开发表、公布或发布（新闻）”
B 专门从事、专攻 C 意识到、领悟 D 假定、猜想
16C．what
he wonders后面是一个宾语从句,从句缺少主语成分,由what充当.
17.A
18A.has our country been
这叫：部分倒装,即：具有否定意义的词放在句首时,主句的助动词（注意,是助动词,而非动词啊）提到主语前面.
楼主的句子中,Never 是个否定词被放到了句首,那么主句的助动词has就得提到主语our country 的前面.所以选A
19D
A 离开 B 注意、留神 C 提供 D 显眼、突出
20D,固定搭配,不相关的意思
