Barriersto Knowledge Transfer
Knowledge transfer is of much importancefor human, without which our world will not be so colorful, and human may benot the most powerful species in the world. We can analyze the influence ofknowledge transfer at three aspects. Firstly, the popularization of correctopinions or methods can promote the social development owning to the guidance theyprovide. Secondly, it also helps people slam the door of wrong and outdatedknowledge while absorb the right parts of it. Thirdly, knowledge transfer makesa contribution to appearance and development of new knowledge since theknowledge is always evolutive.
As is discussed above, knowledge transferplays an important role in our lives, but there are still some barriers toknowledge transfer. I roughly divide these unfavorable factors into two sorts—theobjective ones and the subjective ones.
The knowledge level of people is the firstbarrier to knowledge transfer. Taking the principle of relativity for example,we all know that it is the most correct theory in physics and has solved manyproblems confused people for hundreds of years. However, as the famous physicalscientist Langevon said, there are only twelve people who can understand it. Maybethe amount has increased, but it’s still very little. That’s why human cannotdevelop deeper theories in the cutting edge of physics and science. In pastperiods, the communication was not as convenient as nowadays, which resulted inthat it took a long time to complete the transfer of some given knowledge.
As to the subjective factors, the lack oftrust and resistance to change may be the major ones. Human-beings areaccustomed to absorb knowledge only from the people or books they trust, suchas some teachers and famous people. However, the knowledge transfer may befaced with obstacles because of people’s bigotry. What’s more, human-beingsalways resist the changes, which is resulted from our inherent inertia. But I’mafraid this phenomenon may cause serious problems, even the stagnancy of theknowledge development included. Nowadays the trouble has improved a lot. Everyscholar can deliver his opinion to the whole world, and others who take thesimilar researches can both learn and discuss it.
From my perspective, the objective barriersto knowledge transfer are difficult to eliminate compared to the subjectiveones. The only thing we can do is to build up the consciousness that to absorba new kind of knowledge is always beneficial, whether it’s correct or not.

cast stone：投掷过来的石头（这里根据上下文也有可能是比喻）
be analyzed out of us 意思应该是被我们忽视.

Teachers(主语) that（定语从句,修饰teachers） break down barriers and reach into the souls of the students that(定语从句,修饰students) they are responsible for do（从do开始是谓语） not get the recognition or gratitude（定语从句,省略that/which） they have earned.
所以这是正确的句子,没有语法错误,所以不需要修改.

are abolished
首先是要用被动语态,其次注意用一般现在时态来表示一般将来时态

which 引导定语从句,修饰先行词barriers.
which 之前是系表结构：
主语：The barriers
谓语动词：are

个人倾向于B

好多资料
你只有去GOOGLE搜索“barriers to effective communication”就可以了
以下资料可供参考

世界关注度是能阻止FSS公布产品性能的阻碍之一,如果声誉好的话,他们会向全球出售球体（?）.“但在那之前,我们的产品性能将不会提升,人们得到球体（?）将基于先到先得原则,但我能把他挂在任何地方.事实上,这是整个行动最有趣的地方.”汤姆说.
这里有个别单词如spheres,可能要联系更长的上下文才能理解.很多语义翻译的时候因为没有上下文,因此也很难做到准确.

前面说的是打破壁垒（障碍）
后面的make it应该指的是实现这一点

美国/欧洲农业贸易的技术贸易壁垒

关税壁垒与非关税壁垒对世界贸易的模式有着非常重要的影响.发达国家历来对初级产品保持着低关税,而对半成品和制成品保持着很高的关税.这种关税结构通过打消发展中国家的出口前景来抑制了发展中国家制造业的发展.实际上,发达国家是在国际竞争中保护本国的制造业.对此问题一个可行的解决办法是在世界范围内削弱关税壁垒.
