一、用所给单词的适当形式填空
1. —In my opinion, these letters remind people of care, friendship and love.
—I couldn't agree more. They can also help people come up with the (mean) of time.
2. [2025 安徽中考改编]Come on! You'll discover a new side of yourself when you overcome all the (difficulty).

5. The young man is good at traditional Chinese medicine. He often gives his friends some (use) advice about staying healthy.

1. meaning ——在我看来,这些信件提醒人们关心、友谊和爱。——我完全同意。它们还可以帮助人们理解时间的意义。根据结构“the + ____ + of”可知,空处应填名词,mean 的名词形式为 meaning。再结合语境可知,此处指信件通过唤起人们的情感回忆来帮助他们思考时间的意义,此处 meaning 意为“真正重要性;价值”,为不可数名词。故填 meaning。
2. difficulties 根据空前的“all”可知,空处应填可数名词的复数形式。overcome all the difficulties 表示“克服所有困难”。
3. positively 句意:无论何时我们的老师给我们布置难题,她总会在班上积极地告诉我们“你们能做到”。空处修饰动词 says,要用副词形式,positive 的副词形式是 positively,表示“积极地”。故填 positively。
4. exactly 分析句子结构可知,空处应作副词修饰动词“remember”,exact 的副词形式为 exactly。
5. useful 句意:这个年轻人擅长中医。他经常给朋友们一些关于保持健康的有用建议。形容词修饰名词,根据空后的名词“advice”可知,空处应填 useful。

二、根据汉语意思完成句子(每空一词)
