【正确答案】：
THERE EXIST TRUE SYNONYMS BUT THEY ARE RARE.
ABSOLUTE SYNONYMS ARE WORDS WHICH ARE IDENTICAL IN MEANING IN ALL ITS ASPECTS, I.E. BOTH IN GRAMMATICAL MEANING AND LEXICAL MEANING, INCLUDING CONCEPTUAL AND ASSOCIATIVE MEANINGS. ABSOLUTE SYNONYMS ARE RESTRICTED TO HIGHLY SPECIALIZED VOCABULARY, SUCH AS SCARLET-FEVER/ SCARLATINA IN MEDICINE, AND COMPOSITION/ COMPOUNDING IN LEXICOLOGY.
【题目解析】：本题考查同义词的类别。真正的同义词是存在的，但是数量十分少。绝对同义词是意义完全相同的词，也就是说，语法意义、词汇意义都完全相同。比如医学上的scarlet-fever/scarlatina（猩红热）和词汇学中的composition/compounding（复合词）。
