Read the following passage and blacken the letter A, B, C, or D on your answer sheet to
indicate the correct answer to each of the questions.
Scientists do not yet thoroughly understand just how the body of an individual becomes sensitive
to a substance that is harmless or even wholesome for the average person. Milk, wheat, and egg, for
example, rank among the most healthful and widely used foods. Yet these foods can cause persons
sensitive to them to suffer greatly. At first, the body of the individual is not harmed by coming into
contact with the substance. After a varying interval of time, usually longer than a few weeks, the body

becomes sensitive to it, and an allergy has begun to develop. Sometimes it's hard to figure out if you
have a food allergy, since it can show up so many different ways.
Your symptoms could be caused by many other problems. You may have rashes, hives, joint pains
mimicking arthritis, headaches, irritability, or depression. The most common food allergies are to milk,
eggs, seafood, wheat, nuts, seeds, chocolate, oranges, and tomatoes. Many of these allergies will not
develop if these foods are not fed to an infant until her or his intestines mature at around seven
months. Breast milk also tends to be protective. Migraines can be set off by foods containing tyramine,
phenathylamine, monosodium glutamate, or sodium nitrate. Common foods which contain these are
chocolate, aged cheeses, sour cream, red wine, pickled herring, chicken livers, avocados, ripe bananas,
cured meats, many Oriental and prepared foods (read the labels!).
Some people have been successful in treating their migraines with supplements of B-vitamins,
particularly B6 and niacin. Children who are hyperactive may benefit from eliminating food additives,
especially colorings, and foods high in salicylates from their diets. A few of these are almonds, green
peppers, peaches, tea, grapes. This is the diet made popular by Benjamin Feingold, who has written the
book “Why your Child is Hyperactive”. Other researchers have had mixed results when testing whether
the diet is effective.
Question 22: The topic of this passage is A. reactions to foods B. food and nutrition C. infants and
allergies D. a good diet
Question 23: According to the passage, the difficulty in diagnosing allergies to foods is due to A. the
vast number of different foods we eat B. lack of a proper treatment plan C. the similarity of symptoms
of the allergy to other problems D. the use of prepared formula to feed babies
Question 24: What can be inferred about babies from this passage? A. They can eat almost anything.
B. They should have a carefully restricted diet as infants. C. They gain little benefit from being breast
fed.
D. They may become hyperactive if fed solid food too early.
Question 25: The author states that the reason that infants need to avoid certain foods related to
allergies has to do with the infant's
A. lack of teeth
B. poor metabolism C. underdeveloped
intestinal tract
D. inability to swallow solid foods
Question 26: The word "these" in line 16 refers to A. food additives
B. food colorings
C. innutritious foods
D. foods high in silicates
Question 27: Which of the following was a suggested treatment for migraines in the passage? A.
Eating more ripe bananas B. Avoiding all Oriental foods C. Getting plenty of sodium nitrate D. Using
Vitamin B in addition to a good diet

How men first learnt to invent words is unknown; in other words, the origin of language is a (32)
. All we really know is that men, unlike animals, somehow invented certain sounds to
express thoughts and feelings, actions and things so that they could communicate with each other;
and that later they agreed (33) certain signs, called letters, which could be combined to represent
those sounds, and which could be written down. These sounds, (34)

are called words. Great writers are those who not only have great thoughts but also express these
thoughts in words that appeal powerfully to our minds and emotions. This charming and telling use of
words is what we call literacy type. Above all, the real poet is a master of words. He can (35)

Read the following passage and blacken the letter A, B, C or D on your answer sheet to
indicate the correct answer to each of the questions.
Until recently, hunting for treasure from shipwrecks was mostly fantasy; with recent technological
advances, however, the search for sunken treasure has become more popular as a legitimate
endeavor. This has caused a debate between those wanting to salvage the wrecks and those wanting
to preserve them.
Treasure hunters are spurred on by the thought of finding caches of gold coins or other valuable
objects on a sunken ship. One team of salvagers, for instance, searched the wreck of the RMS Republic,
which sank outside the Boston harbor in 1900. The search party, using side-scan sonar, a device that
projects sound waves across the ocean bottom and produces a profile of the sea floor, located the
wreck in just two and a half days. Before the use of this new technology, such searches could take
months or years. The team of divers searched the wreck for two months, finding silver tea services,
crystal dinnerware, and thousands of bottles of wine, but they did not find the five and a half tons of
American Gold Eagle coins they were searching for.
Preservationists focus on the historic value of a ship. They say that even if a shipwreck's treasure
does not have a high monetary value, it can be an invaluable source of historic artifacts that are
preserved in nearly mint condition. But once a salvage team has scoured a site, much of the
archaeological value is lost. Maritime archaeologists who are preservationists worry that the success of
salvagers will attract more treasure-hunting expeditions and thus threaten remaining undiscovered
wrecks. Preservationists are lobbying their state lawmakers to legally restrict underwater searches and
unregulated salvages. To counter their efforts, treasure hunters argue that without the lure of gold and
million-dollar treasures, the wrecks and their historical artifacts would never be recovered at all.
Question 41: What is the main idea of this passage? A. Searching for wrecks is much easier with new
technologies like side-scan sonar. B. Maritime archaeologists are concerned about the unregulated
searching of wrecks.
C. The search of the RMS Republic failed to produce the hoped-for coins.
D. The popularity of treasure seeking has spurred a debate between preservationists and salvagers.
Question 42: The author uses the phrase "mint condition" in line 12-13 to describe A. something
perfect B. something significant C. something tolerant
D. something magical
Question 43: All of the following were found on the RMS Republic EXCEPT
A. wine bottles
B. silver tea services C. American Gold Eagle coins
D. crystal dinnerware

treasure-seeking salvagers B. be a diver C. put treasures in a museum
D.
do
archaeological
