【正确答案】：
SYNONYMS MAY DIFFER IN CONNOTATION. MANY SYNONYMS HAVE CLEAR AFFECTIVE VALUES. FOR GROUP (1), THESE THREE ADJECTIVES LITTLE, SMALL, TINY ALL DESCRIBE THE SMALLNESS OF THE BOY. BUT LITTLE SUGGESTS ATTRACTIVENESS AND PLEASANTNESS, TINY IMPLIES THE ABNORMAL GROWTH OF THE CHILD AND SMALL SIMPLY CONVEYS THE IDEA OF BEING NOT BIG. THEREFORE, LITTLE IS APPRECIATIVE, SMALL IS NEUTRAL AND TINY IS DEROGATORY.
SYNONYMS MAY ALSO DIFFER IN APPLICATION. FOR GROUP (2), SENSE AND MEANING ARE SYNONYMOUS AND INTERCHANGEABLE IN SOME CASES. “THE WORD HAS TWO SENSES" MEANS "THE WORD HAS TWO MEANINGS". SENSE AND MEANING ARE INTERCHANGEABLE. "HE IS A MAN OF SENSE" IS ACCEPTABLE, BUT "HE IS A MAN OF MEANING" IS UNACCEPTABLE. THUS, SENSE AND MEANING ARE NOT INTERCHANGEABLE.
【题目解析】：同义词的内涵可能不同。许多同义词都有明确的情感价值。对于(1)组，little, small, tiny这三个形容词都描述了这个男孩的小。但“little”表示吸引力和愉快（暗含可爱的意思），“tiny”表示孩子的异常成长（暗含发育不良的意思），“small”只是传达了“不大”的意思。因此，“little”是褒义的，“samll”是中性的，“tiny”是贬义的。同义词在应用上也可能不同。对于(2)组，sense和meaning在某些情况下是同义词和可互换的。“The word has two senses"(这个词有两个意义)，意思是“"the word has two meanings".(这个词有两个意义)。sense和meaning是可以互换的。“He is a man of sense（他是一个有理智的人）”是可以接受的，但“He is a man of meaning（他是一个有意义的人）”是不可接受的。因此，sense和meaning是不可互换的。
