阅读下面这首宋词,完成后面的题。

水调歌头

杨炎正

把酒对斜日,无语问西风。胭脂何事,都做颜色染芙蓉。放眼暮江千顷,中有离愁万斛,无处落征鸿。天在阑干角,人倚醉醒中。

千万里,江南北,浙西东。吾生如寄,尚想三径菊花丛。谁是中州豪杰,借我五湖舟楫②,去作钓鱼翁。故国且回首,此意莫匆匆。

【注】①杨炎正是一位力主抗金的志士,由于南宋统治者推行投降政策,他的才能、抱负得不到施展。②五湖舟楫:传说范蠡助越灭吴后,弃官归隐,泛舟于五湖之上。

[3] E-mail is not just an electronic mail sent via the Internet.It creates a psychological space in which pairs of people or groups of people communicate with each other.It creates a situation in which human relationships can be unfolded.
