题型:实验题

题目:

在使用伏安法测量小灯泡在不同电压下的电阻值的实验中,采用如图1所示的电路可以方便地调节灯泡两端的电压值。图中变阻器的总电阻值R1和R2的大小满足R1=10R2

① 在实验中,为了使被测电阻RX的电压在开始时有最小值,在闭合电键前,变阻器R1和R2的滑动端P1和P2应分别放在各自的       端和        端.

② 采用这个电路能够达到精细调节Rx两端电压的目的。其中变阻器           是进行精细调节使用的。 

③ 按照所给的电路图将如图2所示的实物图连接成测量电路。

James Joyce revolutionized the novel, the short story, and modern literature as we know it. He was born in Dublin, the first of 10 children in a Catholic family. His father was a civil servant whose poor financial judgment left the family impoverished for much of Joyce’s youth. Young James attended Dublin’s fine Jesuit schools, which gave him a firm grounding in theology and classical languages--subjects that appeared repeatedly in his later work. The story of his early life and his intellectual rebellion against Catholicism and Irish nationalism are told in the largely autobiographical novel A Portrait of the Artist as a Young Man.

In 1902, at the age of 20, Joyce left Dublin to spend the rest of his life in Paris, Trieste, Rome, and Zurich, with only occasional visits back home. Despite this self-imposed exile, Dublin was the setting for most of his writings. Dubliners (1914), Joyce’s most accessible work, is a collection of short stories describing the paralyzing social mores of middle-class Catholic life. "The Dead," the final story in the collection, is frequently listed as one of the finest short stories ever written.

Joyce’s next book, Ulysses, took seven years to write; once he finished writing it, he almost couldn’t find anyone to publish it. Upon the novel’s publication, both Ireland and the United States immediately banned it as obscene. Despite these obstacles, Ulysses has come to be generally recognized as the greatest twentieth-century novel written in English. The novel was revolutionary in many ways. The structure was unique: Joyce recreated one rill day in the life of his protagonist, Leopold Bloom, and modeled the actions of the story on those of Ulysses in the Odyssey. In recounting Bloom’s day, Joyce mentions everything that happens to Bloom--including thoughts, bodily functions, and sexual acts--providing a level of physical actuality that had never before been achieved in literature. To provide a psychological insight comparable to the physical detail, Joyce employed a then-revolutionary technique called stream of consciousness, in which the protagonist’s thoughts are laid bare to the reader.

From 1922 until 1939, joyce worked on a vast, experimental novel that eventually became known as Finnegan’s Wake. The novel, which recounts "the history of the world" through a family’s dreams, employs its own "night language" of puns, foreign words, and literary allusions. It has no clear chronology or plot, and it begins and ends on incomplete sentences that flow into each other. Many of Joyce’s supporters thought he was wasting his time on the project, although the playwright Samuel Beckett, who later won the Nobel Prize for Literature, helped Joyce compile the final text when his eyesight was failing. Today, Finnegan’s Wake is viewed as Joyce’s most obscure and possibly most

The author most likely mentions James Joyce’s childhood, family, and education to serve what purpose ?()

A. To suggest that he had to write in order to make a living

B. To suggest that he became a writer because of his father’s influence

C. To provide the background and cultural context for his literary work

D. To provide evidence that his literary genius was present when he was a child

E. To explain his opposition to Catholicism and socialism in his later life
