George Bernard Shaw(1856—1950)was born in Dublin, Ireland. At the age of 14, after graduating from middle school, Shaw was put into a job as clerk in a land agent’s office. At 20 he went to London where he remained jobless for 9 years, devoting much time to self-education. Meantime, Shaw took an active part in the socialist movement. A contemporary of Shaw’s thus wrote of him: "I used to be a daily frequenter of the British Museum Reading Room. Even more assiduous in his attendance was a young man. ...My curiosity was piqued by the odd conjunction of his subjects of research. Day after day for weeks he had before him two books—Karl Marx’s ’Das Kapital’ (in French), and an orchestral score(管弦乐乐谱) of ’Tristan and Isolde’."
Though Shaw admitted Marx’s great influence on him, he failed to grasp the necessity of a revolutionary reconstruction of the world. A strong influence was exercised on Shaw by the Fabian society, the English reformist organization.
In the early period of his literary career, Shaw wrote some novels, "An Unsocial Socialist" and others, in which he developed the traditions of critical realism, bitterly criticizing the stupidity, snobbishness and petty tyranny of the middle class. In the nineties Shaw turned to the theatre, first working as a dramatic critic, then writing plays for the stage. His role in the development of dramaturgy is very great. Shaw was an enemy of "art for art’s sake". He wrote, "for art’s sake I will not face the toil of writing a sentence." He used the stage to criticize the evils of capitalism. He wrote 51 plays in total, the important ones including "Widower’s Houses", "Saint Joan" and "The Apple Cart". In his plays Shaw laid bare the gross injustice and utter inhumanity of the bourgeois society. This he achieved not so much by the structures of plots in his plays as by the brilliant dialogues between the characters. His exposure of capitalist society is very significant and it places Shaw among the most important representatives of critical realism in modern English literature.
Which of the following statements is true

A:In his teens, Shaw took an active part in the socialist movement. B:In his twenties, Shaw was out of work for 9 years. C:In his works, Shaw spoke for the socialism movement by criticizing the evils of capitalism. D:In his nineties, Shaw turned to the theatre.

Reading is thought to be a kind of conversation between the reader and the text. The reader puts questions, as it were, to the text and gets answers. In the light of these he puts further questions, and so on.
For most of the time this "conversation" goes on below the level of consciousness. At times, however, we become aware of it. This is usually when we are running into difficulties, when mismatch is occurring between expectations and meaning. When successful matching is being experienced our questioning of the text continues at the unconscious level.
Different people converse with text differently. Some stay very close to the words on the page; others take off imaginatively from the words, interpreting, criticizing, analyzing and examining. The former represents a kind of comprehension which is written in the text. The latter represents higher levels of comprehension. The balance between these is important, especially for advanced readers.
There is another conversation which from our point of view is equally important, and that is to do not with what is read but with how it is read. We call this a "process" conversation as opposed to a "content" conversation. It is concerned not with meaning but with the strategies (策略) we employ in reading. If we are an advanced reader our ability to hold a content conversation with a text is usually pretty well developed. Not so our ability to hold a process conversation. It is precisely this kind of conversation that is of importance when we are seeking to develop our reading to meet the new demands being placed upon us by studying at a higher level.

A:conscious and unconscious levels of comprehension B:the readers’ expectations and the meaning of a text C:lower and higher levels of comprehension D:interpreting and criticizing a text
