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
Martin Luther King, Jf., is well- known for his work in civil rights and for his many famous speeches, among which is his moving “ I have a dream” speech. But fewer people know much about King’s childhood. M.L., as he was called, was born in 1929 in Atlanta, Georgia, at the home of his maternal grandfather. M.L.’s grandfather purchased their home on Auburn Avenue in 1909, twenty years before M.L was born. His grandfather allowed the house to be used as a meeting place for a number of organizations dedicated to the education and social advancement of blacks. M.L. grew up in the atmosphere, with his home being used as a community gathering place, and was no doubt influenced by it.
M.L.’s childhood was not especially eventfully. His father was a minister and his mother was a musician. He was the second of three children, and he attended all black schools in a black neighborhood. The neighborhood was not poor, however. Auburn Avenue was an area of banks, insurance companies, builders, jewelers, tailors, doctors, lawyers, and other businesses and services. Even in the face of Atlanta’s segregation, the district thrived. Dr. King never forgot the community spirit he had known as a child, nor did he forget the racial prejudice that was a huge barrier keeping black Atlantans from mingling with whites.   
When was M.L. born?                                         
A.in 1909    
B.in 1929     
C.in 1949   
D.20 years after his parents had met.

            Most of us own modern gadgets such as mobile phones, or digital cameras. We may carry them round in our pockets, or attach them to our bodies. But not for much longer! So far designers have succeeded in (25) ________ tiny bits of technology directly into our clothing. In actual fact “cyberfashion” is the latest trend! One example, the Musical Jacket, is already in the shops and stores. This jacket is silk. It is (26) _______ by a keyboard, also manufactured from fabric, which is connected to a tiny device (27) _______ plays music.
            At present, you have to touch a shoulder pad to hear the music. But in the future, you will be able to operate the device just by turning your wrist or walking! For many athletes, scientists have invented a smart shirt which measures your heart rate, body temperature and respiration rate! (28) _______, the most romantic piece of cyberfashion must be the Heartthrob Brooch. This item of jewellery, made from diamonds and rubies, has two miniature transmitters.

      An air pollutant is defined as a compound added directly or indirectly by humans to the atmosphere in such quantities as to affect humans, animals, vegetation, or materials adversely. Air pollution requires a very flexible definition that permits continuous change. When the first air pollution laws were established inEngland in the fourteenth century, air pollutants were limited to compounds that could be seen or smelled - a far cry from the extensive list of harmful substances known today. As technology has developed and knowledge of the health aspects of various chemicals has increased, the list of air pollutants has lengthened. In the future, even water vapor might be considered an air pollutant under certain conditions.
      Many of the more important air pollutants, such as sulfur oxides, carbon monoxide, and nitrogen oxides, are found in nature. As the Earth developed, the concentration of these pollutants was altered by various chemical reactions; they became components in biogeochemical cycles. These serve as an air purification scheme by allowing the compounds to move from the air to the water or soil. On a global basis, nature's output of these compounds dwarfs that resulting from human activities.
      However, human production usually occurs in a localized area, such as a city. In such a region, human output may be dominant and may temporarily overload the natural purification scheme of the cycles. The result is an increased concentration of noxious chemicals in the air. The concentrations at which the adverse effects appear will be greater than the concentrations that the pollutants would have in the absence of human activities. The actual concentration need not be large for a substance to be a pollutant; in fact, the numerical value tells us little until we know how much of an increase this represents over the concentration that would occur naturally in the area. For example, sulfur dioxide has detectable health effects at 0.08 parts per million (ppm), which is about 400 times its natural level. Carbon monoxide, however, has a natural level of 0.1 ppm and is not usually a pollutant until its level reaches about 15 ppm.
 
The word "localized" in the third paragraph is closest in meaning to _______.
A.circled  
B.encircled
C.surrounded
