【正确答案】：
AFFECTIVE MEANING INDICATES THE SPEAKER‘S ATTITUDE TOWARDS THE PERSON OR THING IN QUESTION. WORDS THAT HAVE EMOTIVE VALUES MAY FALL INTO TWO CATEGORIES: APPRECIATIVE OR PEJORATIVE. WORDS OF POSITIVE OVERTONES ARE USED TO SHOW APPRECIATION OR THE ATTITUDE OF APPROVAL, WHILE THOSE OF NEGATIVE CONNOTATIONS IMPLY DISAPPROVAL, CONTEMPT OR CRITICISM IN SENTENCE 1, AMBITION IS OBVIOUSLY USED IN GOOD SENSE SHOWING APPROVAL ON THE PART OF THE SPEAKER. IN SENTENCE 2, AMBITION UNDOUBTEDLY CONVEYS A PEJORATIVE OVERTONE. THEREFORE, TO A LARGE EXTENT THE AFFECTIVE MEANING OF THE WORD DEPENDS ON THE CONTEXT WHERE THE WORD IS USED.
【题目解析】：情感意义是指说话人对所关心的人或事物的态度。有情感价值的词可以分为两类：褒义词或贬义词。带有积极意味的词语被用来表示赞赏或赞同的态度，而消极内涵的词语则意味着不赞成、蔑视或批评。 这些词的赏识或贬义通常是在语境中表达出来的。 在句子1中，ambition（野心）这个词显然是在褒义上使用的，加上work hard（努力工作）的词语，表明说话人的赞同。在句子2中，ambition（野心）和另外两个词envy（嫉妒）和greed（贪婪）一样，无疑是带有贬义的语气。因此，在很大程度上，这个词的情感意义取决于该词使用的上下文语境。
