Question 1 is based on the news report you have just heard.

听力原文：

    A New Jersey black bear that walks upright on his two back legs and has become a social media darling has re-emerged and has been captured on video months after its last sighting. The bear, named Pedals was spotted in the town of Oak Ridge. In the video posted to Facebook featuring the bear, it appeared to be in relatively good health and was moving quickly.

    (1) Pedals apparently has an injured leg or paw that doesn’t allow it to walk comfortably on all fours, according to experts. Laurence Hajna, spokesman for the State Department of Environmental Protection, said officials expect the bear to make it through next winter.

    (2) The bear first gained fame after it was spotted wandering around neighborhoods and was caught on videos that were posted on social media and shown on national television. Last year, supporters pushed for Pedals to be moved to a shelter, but New Jersey officials have said they won’t allow the bear to be captured and transferred to the facility. “The bear would do better in its natural habitat, and the agency would step in if its condition deteriorated,” they said.

1. What is the probable reason the bear walks upright on its back legs?

解析：D。本题为细节题。问题为：熊用后腿直立行走的可能原因是什么？根据原文“Pedals apparently has an injured leg or paw that doesn’t allow it to walk comfortably on all fours”，可知Pedals是由于有一条腿或爪子受伤而不能四脚着地行走。D选项中“got one of its limbs injured”是对原文中“has an injured leg or paw”的同义替换，为正确答案。
