2009年12月大學(xué)英語四級考試模擬試題(一)

　　Section C

　　Directions: In this section, you will hear a passage three times. When the passage is read for the first time, you should listen carefully for its general idea. When the passage is read for the second time, you are required to fill in the blanks numbered from 36 to 43 with the exact words you have just heard. For blanks numbered from 44 to 46 you are required to fill in the missing information. For these blanks, you can either use the exact words you have just heard or write down the main points in your own words. Finally, when the passage is read for the third time, you should check what you have written.

　　Some people’s ears produce wax like busy little bees. This can be a problem even though earwax appears to serve an important purpose. Experts say it protects and cleans the ear. It (36) traps dirt and other matter and keeps (37) insects out. Doctors think it might also help protect against (38) infections. And the waxy oil keeps ears from getting too dry. So earwax is good. It even has a medical name: cerumen. There are two kinds of cerumen. Most people of (39) European or African ancestry have the “wet” kind: thick and (40) sticky. East Asians commonly have “dry” earwax.

　　But you can’t have too much of a good thing. The glands in the ear canal that produce the wax make too much in some people. Earwax is normally (41) expelled; it falls out of the ear or gets washed away. But extra wax can (42) harden and form a blockage that (43) interferes with sound waves and reduces hearing. (44) People can also cause a blockage when they try to clean out their ears — but only push the wax deeper inside. Earwax removal is sometimes necessary. But you have to use a safe method or you could do a lot of damage.

　　Experts suggest some ways to treat excessive earwax yourself. (45) They say the wax can be softened with mineral oil, or ear drops. Another way to remove wax is known as irrigation. With the head upright, take hold of the outer part of the ear. Gently pull upward to straighten the ear canal. (46) Use a device to gently direct water against the wall of the ear canal. Then turn the head to the side to let the water out.

　　Part IV Reading Comprehension

　　(Reading in Depth)

　　Section A

　　47. D)。此處需要一個(gè)名詞。此處講的是搖滾主要植根于布魯斯、節(jié)奏布魯斯、鄉(xiāng)村音樂、民歌、福音歌以及爵士樂。

　　48. J)。此處需要一個(gè)形容詞。參見上題解析可知，搖滾最終發(fā)展為現(xiàn)代的搖滾音樂。

　　49. A)。此處需要一個(gè)動詞。根據(jù)前面出現(xiàn)的兩個(gè)詞典給出的解釋及后面的內(nèi)容可以推斷，這里是對搖滾進(jìn)行定義。

　　50. L)。此處需要一個(gè)副詞。根據(jù)上下文可知，ALLwords.com與前兩個(gè)詞典的定義不同，它將搖滾定義為20世紀(jì)50年代的音樂而不是現(xiàn)代音樂。

　　51. E)。此處需要一個(gè)副詞。根據(jù)上下文可知，古典搖滾樂通常由如下樂器合奏：一兩把電吉他;一個(gè)弦貝司或電貝司;一組架子鼓。

　　52. G)。此處需要一個(gè)形容詞。根據(jù)下文出現(xiàn)的1940s這個(gè)時(shí)間可知，這里講的是20世紀(jì)40年代末期出現(xiàn)的最早的搖滾風(fēng)格。

　　53. M)。此處需要一個(gè)動詞。根據(jù)下文“or supplemented by the guitar”可知，鋼琴與薩克斯風(fēng)這些早期主打樂器被20世紀(jì)50年代中后期的吉他所取代或補(bǔ)充。
