【正确答案】：
IN THE FIRST SENTENCE, “TELECAST” IS A BLEND, WHICH COMES FROM “TELEVISION + BROADCAST”. IN THE SECOND SENTENCE, “STEREO” IS A WORD FORMED IN THE WAY OF CLIPPING, WHICH COMES FROM “STEREOPHONIC”. SO FROM THESE TWO SENTENCES，WE CAN FIND THAT BLENDING IS THE FORMATION OF NEW WORDS BY COMBINING PARTS OF TWO WORDS OR A WORD PLUS A PART OF ANOTHER WORD, WHILE CLIPPING IS TO SHORTEN A LONGER WORD BY CUTTING A PART OFF THE ORIGINAL AND USING WHAT REMAINS INSTEAD. THEY ARE THE DIFFERENT WAYS OF FORMING NEW WORDS.
【题目解析】：在第一句话中，“电视转播”是一种融合，来源于“电视+广播”。在第二个句子中，“立体声”是一个以截短方式形成的词，它来源于“立体声”。从这两个句子中我们可以看出，拼缀就是把两个单词的一部分或一个单词加上另一个单词的一部分来组成新单词，而截短就是把原来的部分截下来，用剩下的部分来缩短一个较长的单词。它们是形成新词的不同方式。
