Communication is far more than speech and writing. Most of usare aware that we are communicating in many different ways even 1when we are not speaking. The same goes to other social animal 2species. We are rarely taught about this most non-verbal form of 3human communication in school even though it is very important foreffective interaction to others. Grown up in a society, we informally 4learn how to use gestures, glances, slight changes in tone of voice,and other auxiliary communication devices to alter or emphasize how 5we say and do. We learn these highly culture bound techniques over years largely by observing others and imitating them. Linguists refer to all of these auxiliary communication methods 6paralanguage. It is part of the redundancy in communication that helps prevent ineffective communication. It can prevent the wrongmessage from inadvertently being passed on, as is often as the case 7in a telephone call and even more so in a letter. The paralanguage messages that can be observed through face-to-face contact also makes it more difficult to lie or to hide emotions. 8 Paralanguage is often less important in communication than 9what is actually being said orally. It has been suggested that as much as 70% of what we communicate when talking directly with others are through paralanguage. 10
【答案解析】解析:主谓不一致。如果主语由“百分数/分数+of短语”构成,其谓语动词的单复数由of短语中的名词类别而定。此处that引导的名词性从句中的主语为as much as 70% of what we communicate,of后的短语表达的是不可数的概念,因此谓语动词应该使用单数is。句意为“在我们与他人直接交谈的过程中,70%的表达是通过副语言来完成的。”
