再问： The Great Wall is the only one of the buildings on the earth that IS seen from the moon. is是单数 可是Tom isn't the only one of the boys who HAVE passed the exam have又是复数啊 矛盾。。
再答： 记住， isn't the only one of the boys who HAVE 裏面有否定词not------有了not,就不是你所涉及的句子的范围了。 记住：在1 和2裏面往往是肯定句，不太可能是否定句 is NOT the only one of the boys who HAVE ===is JUST one of the boys who have - -- - (注意上面的大写，再思考一下，然後语感就出来了。祝你愉快。)
