And do they have enough food to eat?There are more than 80 pandas living here at the Chengdu Panda Breeding Base（繁育基地）.The quake was felt strongly in Chengdu.Fortunately，all of the pandas here were out on the grounds when the earthquake hit，so they were very safe.Several days have passed and the earthquake seems to have made no negative（不利的） impact on the pandas.These two baby pandas Chengshuang and Chengdui are playfighting with each other and climbing trees.When they climbed too high，the breeders have to rescue  them from the trees.The quake zone is not only the home of these pandas，it’s also the source of their food.Fortunately，enough bamboo(竹子) has been stored away in five bamboo storehouses for the pandas，so there are no worries about food supplies.Wu Kongju，Breeder，Chengdu Panda Breeding Base，said，“When the Wenchuan earthquake happened on May 12，2008，we were unprepared and had a shortage of bamboo.But we’ve been able to handle this earthquake event more smoothly.There are no problems with the food supply.”小题1:When did the 7.0-magnitude earthquake happen in Lushan Sichuan Province?A．On April 28，2013B．On May 12，2008C．On April 20，2013D．On May 20，2013小题2:The underlined word “ rescue” in this passage means ______ in Chinese.A．保存B．阻止C．放任D．营救小题3:How did the Panda Breeding Base deal with the food supply after the earthquake in Wenchan in 2008?A．They built 5 bamboo storehouses to store food for pandas.B．They were unprepared and had a shortage of bamboo.C．They handled this earthquake more smoothly.D．They let pandas out on the grounds.
