The San Diego Zoo has been a lovely home for giant pandas since two of the black-and-white bears came to visit in 1987. This week there was snow in San Diego—well, at least for a lucky group of giant pandas.
Over 15 tons of snow was blown into the San Diego Zoo's panda area on Tuesday morning to give the endangered bears a chance to play. They would experience the snow just like living in their natural habitat.
The snow day was a first for Xiao Liwu whose name means "Little Gift." He was the sixth baby panda born to Bai Yun. Xiao Liwu was jumping on Mom, playing with her and getting used to being thrown in the snow by mama bear. Jennifer Becerra, San Diego Zoo keeper said, "He was really enjoying the snow and running around. I've never seen him so happy."
All the San Diego Zoo’s giant pandas are from China, as part of a long-term captive breeding(人工養殖) program. Four of Xiao Liwu's brothers have already been moved from California to China.
Today there are 44 giant pandas living in zoos outside of China, where the bears' only natural home is. As just 1,600 pandas are thought to be left in the wild, researchers insist that captive breeding is an important way to study and protect the endangered pandas. Not only because of the habitat loss from human activities and low reproductive rates(繁殖率), giant pandas' survival is also affected by climate change. A study showed that global warming could kill much of the bears' main food, bamboo, over the next century.
【小題1】Why was the snow blown into the San Diego Zoo's panda area?

A.To stop the bamboos from dying.
B.To give the pandas a chance to play.
C.To help the pandas live in their natural habitat.
D.To make Xiao Liwu happy.
【小題2】What’s the relationship between Bai Yun and Xiao Liwu?
A.Wife and husband.
B.Father and daughter.
C.Sister and brother.
D.Mother and son.
【小題3】What is NOT the factor that influences the giant pandas' number?
A.The loss of habitat.
B.Low reproductive rates.
C.Human research.
D.Climate change.
【小題4】Which of the following is the best title of this passage?
A.Giant pandas in San Diego Zoo
B.Giant pandas in danger
C.Xiao Liwu’s happy time
D.How to protect giant pandas
【小題5】Which of the following is true according to the passage?
A.Captive breeding is the most useful way to protect giant pandas.
B.More than 44 giant pandas live in zoos outside of China now.
C.China is the only natural home of giant pandas.
D.Xiao Liwu was afraid of being thrown in the snow by mama.

Information is received into our brain by attention, and its quality determines (決定) how well it will be processed, saved and used afterwards.
All information we receive is chosen by our attention. Factors (因素) affecting (影響) our attention are personal interest, experience, ability, feelings, knowledge, environment, timing, and so on. The same information may attract different forms and levels of attention from different people. Some people can get and save the information easily; some may have great difficulty; while others may just turn a blind eye to it. To the same information, one may even pay different levels of attention at different times. But if the facts work together, the quality of attention may be better. Therefore, it is not surprising to see that somebody with average intelligence (智力) can have excellent performances in some fields.
The good news is that a person's attention can be shaped, trained and made stronger by effective exercise. With this in mind, we should keep improving the quality of our attention.
【小題1】"it" in Paragraph 1 means _______.
