  For many people who live in cities, parks are an important part of the landscape. They provide a place for people to relax and play sports, as well as a refuge from the often harsh environment of a city. What people often overlook is that parks also provide considerable environmental benefits.

            One benefit of parks is that plants absorb carbon dioxide - a key pollutant - and emit oxygen, which humans need to breathe. According to one study, an acre of trees can absorb the same amount of carbon dioxide that a typical car emits in 11,000 miles of driving. Parks also make cities cooler. Scientists have long noted what is called the Urban Heat Island Effect: building materials such as metal, concrete, and asphalt absorb much more of the sun’s heat and release it much more quickly than organic surfaces like trees and grass. Because city landscapes contain so much of these building materials, cities are usually warmer than surrounding rural areas. Parks and other green spaces help to mitigate the Urban Heat Island Effect.

            Unfortunately, many cities cannot easily create more parks because most land is already being used for buildings, roads, parking lots, and other essential parts of the urban environment. However, cities could benefit from many of the positive effects of parks by encouraging citizens to create another type of green space: rooftop gardens. While most people would not think of starting a garden on their roof, human beings have been planting gardens on rooftops for thousands of years. Some rooftop gardens are very complex and require complicated engineering, but others are simple container gardens that anyone can create with the investment of a few hundred dollars and a few hours of work.

            Rooftop gardens provide many of the same benefits as other urban park and garden spaces, but without taking up the much-needed land. Like parks, rooftop gardens help to replace carbon dioxide in the air with nourishing oxygen. They also help to lessen the Urban Heat Island Effect, which can save people money.

            In the summer, rooftop gardens prevent buildings from absorbing heat from the sun, which can significantly reduce cooling bills. In the winter, gardens help hold in the heat that materials like brick and concrete radiate so quickly, leading to savings on heating bills. Rooftop vegetable and herb gardens can also provide fresh food for city dwellers, saving them money and making their diets healthier. Rooftop gardens are not only something everyone can enjoy, they are also a smart environmental investment.

  Using the information in paragraph 2 as a guide, it can be inferred that ______.

• Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.

  One of the most interesting authors of the twentieth century, J.R.R Tolkien, achieved fame through his highly  inventive  trilogy,  The  Lord  of  the  Rings.  Born  in  1892,  Tolkien  received  his  education  from Oxford and then served in World War I. After the war, he became a professor of Anglo -Saxon and English language and literature at Oxford University.

  Although published in  1965,  the  three  books that  comprise  the  Lord of  the  Rings  were  written in

  intervals  from  1936  to  1949. This was mainly due to Tolkien's responsibilities as a professor and the outbreak of World War II. By the late 1960s, this fascinating trilogy had become a sociological phenomenon as young people intently studied the mythology and legends created by Tolkien.

  The trilogy is remarkable not only for its highly developed account of historical fiction but also its

  success as a  modern heroic epic. The  main plot describes the struggle  between good and evil kingdom as

  they try to acquire a  magic ring that   has the power to rule the world. The novels, which are set in a time

  called  Middle  Earth,  describe  a  detailed  fantasy  world.  Established  before  humans  populated  the  Earth,

  Middle Earth was inhabited by good and evil creatures such as hobbits, elves, monsters, wizards, and some

  humans.  The  characters  and  the  setting  of  Middle  Earth  were  modeled  after  mythological  stories  from

  Greece and Northern Europe.

  Although readers have  scrutinized  the texts for inner meaning and have tried to connect the trilogy with  Tolkien's real  life experiences  in England during World  War II, he denied the connection. He claims that the story began in his years as an undergraduate student and grew out of his desire to create mythology and legends about elves and their language.

  Tolkien  was  a  masterful  fantasy  novelist  who used  his  extensive  knowledge of  folklore to  create a body of work that is still read and enjoyed throughout the world today.

  The word "fascinating" in the second paragraph could be replaced by _______.

• Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 38 to 42.

  (1) Though Edmund Halley was most famous because of his achievements as an astronomer, he was a scientist of diverse interests and great skill. In addition to studying the skies, Halley was also deeply interested in exploring the unknown depths of the oceans. One of his lesser-known accomplishments that were quite remarkable was his design for a diving bell that facilitated exploration of the watery depths.

  (2) The diving bell that Halley designed had a major advantage over the diving bells that were in use prior to his. Earlier diving bells could only make use of the air contained within the bell itself, so divers had to surface when the air inside the bell ran low. Halley’s bell was an improvement in that its design allowed for an additional supply of fresh air that enabled a crew of divers to remain underwater for several hours.

  (3) The diving contraption that Halley designed was in the shape of a bell that measured three feet across the top and five feet across the bottom and could hold several divers comfortably; it was open at the bottom so that divers could swim in and out at will. The bell was built of wood, which was first heavily tarred to make it water repellent and was then covered with a half-ton sheet of lead to make the bell heavy enough to sink in water. The bell shape held air inside for the divers to breathe as the bell sank to the bottom.

  (4) The air inside the bell was not the only source of air for the divers to breathe, and it was this improvement that made Halley’s bell superior to its predecessors. In addition to the air already in the bell, air was also supplied to the divers from a lead barrel that was lowered to the ocean floor close to the bell itself. Air flowed through a leather pipe from the lead barrel on the ocean floor to the bell. The diver could breathe the air from a position inside the bell, or he could move around outside the bell wearing a diving suit that consisted of a lead bell-shaped helmet with a glass viewing window and a leather body suit, with a leather pipe carrying fresh air from the diving bell to the helmet.

  It is NOT stated in the passage that Halley’s bell _____.
