Section B Directions: In this section, you will hear 3 short passages. At the end of each passage, you will hear some questions. Both the passage and the questions will be spoken only once. After you hear a question, you must choose the best answer from the four choices marked A, B, C and D. 听力原文: Learning a second language is never easy, and, generally speaking, the older one is when one attempts a new language, the more difficult it becomes. This is at least partly due to what is known as language interference, meaning that the linguistic patterns of our first language interfere with those of the second because no two languages have exactly the same sounds and grammatical structures. All languages have obligatory categories of grammar that may be lacking in other languages. Russian unlike English—has an obligatory category for gender which demands that a noun, and often a pronoun, specify whether it is masculine or feminine. Likewise, when translating an English story into Chinese in which a character identified as cousin appears, a Chinese translator requires to know whether it refers to a male or a female, whether the character is older or younger than the speaker, and whether the character belongs to the family of the speaker's father of mother. Therefore 'biaomei' can be translated into English only by the awkward statement 'a female cousin on my mother's side and younger than I'. The Russian/English and Chinese/English examples illustrate the basic problem in any translation No matter how skilled translators, they cannot take the language out of the speech community that uses it. Translation obviously is not a simple two-way street between two languages. Rather, it is a busy intersection among at least two languages with all of their peculiar characteristics, the cultures of the two speech communities, and the speech situation in which the statement was uttered.
