问题 单项选择题

在工程网络计划中,对关键线路描述不正确的是()。

A.双代号网络计划中总持续时间最长

B.单代号网络计划中相邻关键工作时间间隔均为零

C.双代号网络计划中由关键节点组成的线路

D.双代号时标网络计划中没有波形线

答案

参考答案:C

解析:自始至终全部由关键工作组成的线路为关键线路,线路上总的工作持续时间最长的线路为关键线路,A正确;在单代号网络计划中,将关键工作相连,并保证相邻两项关键工作时间间隔为零的线路就是关键线路,B正确;双代号网络计划中,关键节点必然处在关键线路上,但由关键节点组成的线路不一定是关键线路,C不正确;时标网络计划中凡自始至终不出现波形线的线路即为关键线路,D正确。

James Joyce was an Irish novelist who revolutionized the methods of depicting characters and developing a plot in modern fiction. his astonishing way of constructing a novel, his frank portrayal(描画, 描写)of human nature in his books, and his complete command of English have made him one of the outstanding influences on literature in the 20th century. Many critics judge that he is second only to Shakespeare in his mastery of the English language. Joyce was deeply influenced by Ireland and wrote all his books about Dublin.

When he was in Dublin College, he studied languages and spent his spare time reading books. He refused to take part in the nationalist movement like his fellow students, but he became passionately(热情地, 热烈地)interested in literature. He wrote outspoken articles of literary criticism that shocked his teachers and even taught himself norwegian(挪威语)so that he could read Ibsen’s(挪威剧作家及诗人)works in the original.

When he graduated in 1902, he knew he would become a writer and an exile(流犯, 被放逐者), because he felt he could not be one without the other. In order to preserve his ideal of writing truthfully, fully, and as objectively as he knew how, about the people and places he knew best, he had to escape from all temptations to become involved in popular opinion or public life. He went to France, Italy and Switzerland, where he lived in poverty and obscurity for the first 20 years, only returning to Ireland when his mother was dying. Except for a couple of brief trips, he stayed abroad all his life.
