主题公园的北极熊宝宝
A Queensland theme park is celebrating after a polar bear gave birth to two lovely cubs last week. The cubs were delivered from 16-year-old polar bear Liya at Sea World on the Gold Coast in the early hours of last Wednesday.
A Sea World spokesperson said both cubs are doing really well so far. “They are making all the right noises and feeding on mum's milk,”the spokesperson said. The twins are the third and fourth cubs to be born at the park's Polar Bear Shores exhibit since it opened in 2000.Henry and another cub —which didn't survive —were born in 2013 to Liya.
Marine scientist Trevor Long said their delivery is important to the long-term survival of polar bears. “There are not a lot of theme parks keeping polar bears in the world,” he said. “There are about 22,000 to 30,000 polar bears in the world— they are listed as the animals in danger, and it's very important for people to take action now. During the recent years, we're seeing a much shorter winter and these bears are not being able to reach their full potential.”
The new cubs are being cared for by their mother in a specially made cage. Sea World staff are looking after them with great care. Mr Long said the first couple of weeks are important to the bears’ survival and staff are content with the cubs at this stage. Both bears were born blind and weighed about just over half a kilogram. Like their older brother Henry, the cubs are expected to weigh around 250kg by the time they are two and a half years old. Mr Long said both cubs will be moved to a public show sometime in September if everything goes well.

1.The underlined word “cubs” may refer to _____.
A the theme parks
B the baby bears
C the lovely coasts
D the polar beaches
解析：选B。词义推测题。 从后面的The cubs were delivered from 16-year-old polar bear Liya at Sea World on the Gold Coast可以得知它们是16岁的北极熊所生的，因此可以推知cubs在此处指的是北极熊宝宝。故选B。
2.How many Liya’s children have survived so far?
A Five.
B Four.
C Three.
D Two.
解析：选C。C 细节理解题。根据第二段第三句的The twins are the third and fourth cubs to be born at the park’s Polar Bear Shores可以得知Liya生了四个宝宝；结合该段最后一句的Henry and another cub—which didn’t survive—were born in 2013可知亨利和另一只没有存活下来的幼崽于2013年出生，即前面两只中有一只没有存活下来，因此现在活着的有三只。故选C。
3.What made the polar bears face the danger of dying out?
A The staff’s carelessness.
B The change of climate.
C The low birth weight.
D The fewer theme parks.
解析：选B。推理判断题。根据第三段第四句的During the recent years, we're seeing a much shorter winter可以得知近年来冬天变短了才使得北极熊没法生长到它们应该长到的那么大，所以是气候变化才使得北极熊面临数目减少的危险。故选B。
4.How did the staff like the cubs?
A They were satisfied with them.
B They felt confused with them.
C They were moved by them.
D They felt sorry to them.
解析：选A。推理判断题。根据文章最后一段第二句的Mr Long said the first couple of weeks are important to the bears’ survival and staff are content with the cubs at this stage可以得知那些员工对北极熊宝宝（的情况）很满意。故选A。
