However, Liu Shan was such an incompetent leader that the heavy responsibility of governing the Shu fell to the Prime Minister, Zhuge Liang. Fearing he would fail in the charge Liu Bei had given him, Zhuge Liang worked nightand day and did everything himself. Hoping to increase the Shu’s and strength, he persistently sought to unite with the kingdom of Wu against the kingdom of Wei.After a period of preparation, Zhuge Liang decided the time was ripe for an attack to the north. However, this attack was not successful. Zhuge Liang could only return to Shu and wait for his next opportunity to launch a campaign against Wei.After saving tax revenue for a few more years, Zhuge Liang decided to try again. When he was about to leave, he wrote a message for Liu Shan in which he described in detail the relative circumstances of Shu and Wei. He explained that the powers of the two kingdoms had not been mutually agreed upon. Given the situation, if Shu were not to attack Wei now, Wei would soon attack Shu. Liu Shan read the message and agreed that Zhuge Liang should dispatch the troops to the north. This message is what has become known in history as “The Pre-Dispatch Message.” At the end of it, Zhuge Liang wrote “I will spare no effort (literally “bow to exhaustion”) and fig ht with my last breath.” to indicate his sincerity and his wish to serve his country.Unfortunately, the Wei kingdom was much stronger than the Shu kingdom, and this campaign was also unsuccessful. However, Zhuge Liang refused to be discouraged; he continued to look for a chance to advance, driving the army against the power of Wei, until he finally became ill and died in camp with the army. In this way, he fulfilled his aspiration to “spare no effort and fight with his last breath” for Shu.Task TwoTranslate the following passage into Chinese.“朝九晚五”用来形容传统甚至可能单调的工作。
它意味着单调或不起眼的职业，含贬义。
它也表明“朝九晚五”的人通常是大公司的职员而非老板。
如果用作中性词，它指有固定的工作时间和较低的职业风险，但仍属于普通职员的工作。
“朝九晚五”源于美国传统的工作时间：周一到周五，上午九点到下午五点。
它代表一周工作五天，每天工作八小时，总共四十小时的工作周。
实际工作时间常为三十五小时到四十八小时不等，看是否包含休息时间而定。
在许多传统的白领岗位上，员工上班时间需要在办公室待命。
尽管工作时间变得灵活有弹性，但“朝九晚五”一词仍被广泛使用。
