But try watching them without the background music and you just might decide they39。re not so different after all. Music and movies have been closely connected since the beginning of the film industry—even before the voices of actors were recorded. In movies, music helps to provide a sense of time and place, convey ideas about the characters and, most importantly, draw emotions out of the audience. Studies have long shown that our heart rates and anxiety levels rise and fall depending on the speed of the music we hear. Using this knowledge, posers use sudden changes in film music speed to create fear among audiences. Slowing the speed of the music will have the opposite effect, bringing about a sense of peace or a dreamlike quality. The use of dissonant (不和諧的) tones and noises is another technique that heightens tension. Humans naturally bee unnerved when we hear dissonant sounds because such noises are usually associated with danger, like those that animals make to warn against predators (捕食者). As crucial as it is, the best film music is subtle. All that audiences are supposed to feel is a heightened sense of emotion—they shouldn39。t realize what39。s causing it. Only when the music is taken out of the film should audiences understand its effects. In keeping with this principle, some filmmakers are even using what39。s called infrasound (次聲波) to arouse fear. While we may not be able to hear it because its frequency is below the range of the human ear, infrasound has been proven to cause anxiety, tremble and even sorrow. For example, infrasound was used in the soundtrack of the 2007 horror movie Paranormal Activity, and audiences reposed extremely high fear levels despite the 1ack of action throughout the movie. It doesn39。t affect everyone equally, said British science writer Philip Ball, author of The Music Instinct, but he predicted that we will see more of it used in movies in the future.（1）What is the difference between a horror movie and a edy?

Only when the music is taken out of the film should audiences understand its effects.可知，觀眾應(yīng)該感受到的只是一種強(qiáng)烈的情感——他們不應(yīng)該意識到是什么導(dǎo)致了這種情感。只有當(dāng)音樂被從電影中刪除時，觀眾才能理解它的影響。所以這段在解釋最好的電影音樂是不易被觀眾察覺的音樂。也就是對subtle的解釋。故第三段加下劃線的subtle一詞是C選項(xiàng)“不明顯的”。故選C。 （4）考查細(xì)節(jié)理解。根據(jù)最后一段中的but he predicted that we will see more of it used in movies in the future可知，但他預(yù)測“我們將來會看到更多的電影會使用它”。所以從最后一段可知，infrasound將在未來的電影中被更多地使用。故選D。 【點(diǎn)評】本題考點(diǎn)涉及細(xì)節(jié)理解，詞義猜測和推理判斷三個題型的考查，是一篇文化類閱讀，考生需要準(zhǔn)確掌握細(xì)節(jié)信息，同時根據(jù)上下文的邏輯關(guān)系，進(jìn)行分析，推理，從而選出正確答案。7．閱讀短文，從短文后每題所給的A、B、C和D四個選項(xiàng)中，選出最佳選項(xiàng)。 Over the years, cheerleading has taken two primary forms: gametime cheerleading and petitive cheerleading. Gametime cheerleaders39。 main goal is to entertain the crowd and lead them with team cheers, which should not be considered a sport. However, petitive cheerleading is more than a form of entertainment. It is really a petitive sport. Competitive cheerleading includes lots of physical activity. The majority of the teams require a certain level of tumbling (翻騰) ability. It39。s a very mon thing for gymnasts, so it39。s easy for them to go into petitive cheerleading. Usually these cheerleaders integrate lots of their gymnastics experience including their jumps, tumbling, and overall energy. They also perform lifts and throws. This is where the fliers are thrown in the air, held by bases in different positions that require strength and working with other teammates. Competitive cheerleading is also an activity that is governed by rules under which a winner can be declared. It is awarded points for technique, creativity and sharpness. Usually the more difficult the action is, the better the score is. That39。s why cheerleaders are trying to experience great difficulty in their performance. Besides, there is also a strict rule of time. The whole performance has to be pleted in less than three min
