In the early days of sea travel, seamen on long voyages lived exclusively on salted meat and biscuits. Many of them died of scurvy (壞血病), a disease of the blood which causes swollen gums, livid white spots on the flesh and general exhaustion. On one occasion, in 1535, an English ship arrived in Newfoundland with its crew desperately ill. The men??s lives were saved by Iroquois Indians who gave them vegetable leaves to eat. Gradually it came to be realized that scurvy was caused by some lack in the sailors?? diet and Captain Cook, on his long voyages of discovery to Australia and New Zealand, established the fact that scurvy could be warded off by the provision of fresh fruit for the sailors.

       Nowadays it is understood that a diet which contains nothing harmful may yet result in serious disease if certain important elements are missing. These elements are called “vitamins”. Quite a number of such substances are known and they are given letters to identify them, A, B, C, D, and so on. Different diseases are associated with deficiencies of particular vitamins. Even a slight lack of Vitamin C, for example, the vitamin most plentiful in fresh fruit and vegetables, is thought to increase significantly our susceptibility (敏感度) to colds and influenza.

The vitamins necessary for a healthy body are normally supplied by a good mixed diet, including a variety of fruit and green vegetables. It is only when people try to live on a very restricted diet, say during extended periods of religious fasting (齋戒), or when trying to lose weight, that it is necessary to make special provision to supply the missing vitamins.

51. Scurvy is a disease that is provoked by ____

     A. salted meat and biscuits              B. exhaustion

     C. want of some essential substances      D. lack of fresh vegetables and fruits

52. In the last sentence of Paragraph 1, “warded off” could probably be replaced by____.

     A. got rid of     B. killed     C. avoided     D. cleared away

53. To avoid such disease as scurvy, it??s better for us ____.

A. not to eat much salted meat

B. to supplement our diet with various vitamin pills

C. to have more fresh fruit and vegetables

D. to develop a good dietary habit

54. Based on the passage we can safely conclude that if our diet is not comprehensive enough ____.

A. vitamin pills are of no avail

B. nutritious food might be unhealthy

C. vegetable leaves can be a good remedy

D. religious fasting may help out a lot

55. Which of the following sentences best expresses the central ideal of the passage?

A. Deficiencies of Vitamin C may cause serious diseases.

     B. Fresh fruit and green vegetables contain enough nutrition that is necessary for a healthy body.

     C. Vitamins play a vitally important role in people??s health.

     D. A good mixed diet normally supplies sufficient vitamins for us.

D
Parties, iPods, concerts, movies, TV shows, video games, traffic. All of these things of the modern world make life entertaining and enjoyable. But our 21st-century lifestyle is also loud and, if we don’t take notice, it can have an effect on our hearing.
Most teenagers don’t think about hearing loss. But if you experience any of the following symptoms（癥狀）, you may already be hearing damaged: you make efforts to hear normal talk, you have to turn up the TV or radio so high that others complain, you watch other people’s expressions to understand what they are saying, you ask people to repeat themselves, you misunderstand what people are saying or you hear ringing in your ears.
iPods and other MP3 players are as common as the clothes you wear, and just as fashionable. But if you turn up an iPod to more than 60 percent of its maximum volume（最大音量）, and listen to music for more than an hour, you are asking for trouble. And, it does not matter if the music you play is classical, rock or heavy metal.
Some researchers find that young people who break the so-called 60-percent/60-minute rule in listening to iPods are at the risk of suffering hearing loss.
Why is an iPod dangerous? With ear buds placed directly in the ear canal and high-volume music played over a long period of time, it’s like working in a loud factory all day, being a maintenance（修理）person under a jet airplane or using a jackhammer（手提鉆）on a building site.
Similarly, iPod music can cause a short time or permanent（永久的）hearing damage. A loud iPod can cause a ruptured（破裂的）eardrum and, over time, may cause permanent damage to the tiny hairs in the inner ear. If these tiny hairs are damaged, they cannot effectively send sounds to the auditory nerves（聽覺神經(jīng)）that connect to the brain. If this happens, hearing loss becomes permanent.
【小題1】Which of the following shows that you are suffering hearing loss?

A．You are interested to listen to others’ talking.
B．You have to read others’ expressions to understand them.
C．You can only understand others over the phone.
D．You always think you hear the ringing of the phone.
【小題2】 Which of the following is TRUE when you listen to music?
A．Listen at least an hour every time.
B．Turn up the volume to the highest level.
C．keep the sound lower than 60% of its highest volume.
D．Choose classical, rock or heavy metal music.
【小題3】What is the correct order of causing permanent hearing loss?
a. The eardrum is broken.
b. The auditory nerves cannot receive sounds.
c. Tiny hairs are damaged.
d. Ear buds are placed directly in the ear canal.
e. High-volume music is played over a long time.
A．d-a-c-b-eB．e-c-a-b-dC．b-c-a-d-eD．d-e-a-c-b
【小題4】This passage is mainly about      .
A．music that teenagers likeB．hearing problems caused by the loud world
C．ways that teenagers enjoy music D．dangerous modern lifestyles of teenagers.

[1]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 traps dirt and other matter and keeps insects out. Doctors think it might also help protect against infections. And the waxy oil keeps ears from getting too dry.

[2]So earwax is good. It even has a medical name: cerumen. And there are two kinds. Most people of European or African ancestry have the "wet" kind: thick and sticky. East Asians commonly have ___________.But you can have too much of a good thing.

[3]The glands(腺體) in the ear canal that produce the wax make too much in some people. Earwax normally falls out of the ear or gets washed away. But extra wax can harden and form a blockage that interferes with sound waves and reduces hearing. 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.

[4]Experts at N.I.H., the National Institutes of Health, suggest some ways to treat excessive earwax yourself. One 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. Use an injector device to gently direct water against the wall of the ear canal. Then turn the head to the side to let the water out.

[5]The experts at N.I.H. say you may have to repeat this process a few times. Use water that is body temperature. If the water is cooler or warmer, it could make you feel dizzy. Never try irrigation if the eardrum is broken. It could lead to infection and other problems.

[6]After the earwax is gone, gently dry the ear. But if irrigation fails, the best thing to do is to go to a

 health care provider for professional assistance.
