SECTION B PASSAGES
Directions: In this section, you will hear several passages. Listen to the passages carefully and then answer the questions that follow.
听力原文： When a new movement in Art attains a certain vogue, it is advisable to find out what its advocates are aiming at, for, however far-fetched and unreasonable their contents may seem today, it is possible that in years to come they may be regarded as normal. With regard to Futurist poetry, however, the case is rather difficult, for whatever Futurist poetry may be even admitting that the theory on which it is based may be right - it can hardly be classed as Literature.
This, in brief, is what the Futurist says for a century, past conditions of life have been continually speeding up, till now we live in a world of noise and violence and speed. Consequently, our feelings, thoughts and emotions have undergone a corresponding change. This speeding up of life, says the Futurist, requires a new form. of expressions. We must speed up our literature too, ff we want to interpret modern stress. We must pour out a cataract of essential words, unhampered by stops, or qualifying adjectives, or finite verbs. Instead of describing sounds we must make up words that imitate them; we must use many sizes of type and different colored on the same page, and shorten or lengthen words at will.
According to the passage, when should we do when novel ideas appear？
