例:Science is the production of new knowledge that can be applied or not, since technology is the application of knowledge to the production of some products, machinery or the like.
例:The idea that learn a foreign language is hard work is realized by every student.分析句子结构可知:the idea是主语;is realized是谓语部分;that引导同位语从句。从句中learn a foreign language是主语,而learn是动词形式,应改为动名词“learning”。
