      【A】The Sloth:
      Nature’s Couch Potato Nature is a dangerous place. To survive, animals have to be fast, strong, or smart. But the sloth uses a different way to live — it is slow, weak and lazy. 
      The sloth is the world’s slowest animal. It lives in the wet forests of South America, and it spends most of its time hanging from tree branches. It moves once in a while to eat a leaf or two. Because it moves so little, a type of green bacteria grows on its body. 
      It may not sound wonderful, but this type of bacteria protects the sloth in dangerous forests. To most predators, a sloth looks more like a big green plant than a delicious meal. In fact, more sloths die from touching electrical lines than from being eaten.

      【題組】31. What are “predators”?
      (A) The sloth’s friends.
      (B) The hunters for the sloth.
      (C) The sloth itself.
      (D) The sloth’s fans.

       Passage 1 
       The La Brea tarpits, located in Hancock Park in the Los Angeles area, have proven to be an extremely fertile source of Ice Age fossils. Apparently, during the period of the Ice Age, the tarpits were covered by shallow pools of water; when animals came there to drink, they got caught in the sticky tar and perished. The tar not only trapped the animals, leading to the death, but also served as a remarkably effective preservant, allowing near-perfect skeletons to remain hidden until the present era. 
       In 1906, the remains of a huge prehistoric bear discovered in the tarpits alerted archeologists to the potential treasure lying within the tar. Since then thousands and thousands of well-preserved skeletons have been uncovered, including the skeletons of camels, horses, wolves, tigers, sloths, and dinosaurs.

      【題組】40. Which of the following is NOT mentioned as an example of a skeleton found in the tarpits?
      (A) a snake
      (B) a sloth
      (C) a horse
      (D) a bear
