Spot and Stripe are the first tiger cubs that have ever been born here. Globally, a third of Sumatran cubs in zoos don't make it to adulthood, so I decided to give them round­the­clock care at home. 课时作业(三) I've got two children—the younger one, Kynan, was extremely happy about the tigers arriving—but all of us really looked forward to being part of their lives and watching them grow. I wasn't worried about bringing them into my home with my wife and kids. These were cubs. They weighed about 2.5 kg and were so small that there was absolutely no risk. As they grew more mobile, we let them move freely around the house during the day, but when we were asleep we had to contain them in a large room, otherwise they'd get up to mischief. We'd come down in the morning to find they'd turned the room upside down, and left it looking like a zoo. 课时作业(三) Things quickly got very intense due to the huge amount of energy required to look after them. There were some tough times and I just felt extremely tired. I was grateful that my family was there to help. We had to have a bit of a production line going, making up “tiger milk”， washing baby bottles, and cleaning the floors. When Spot and Stripe were four months old, they were learning how to open doors and jump fences, and we knew it really was time for them to go. It was hard for us to finally part with them. For the first few days, Kynan was always a bit disappointed that the cubs weren't there. 课时作业(三) I'm not sad about it. I'm hands­on with them every day at the zoo, and I do look back very fondly on the time that we had them. 篇章导读：本文是一篇记叙文。文章讲述了作者在家中饲养老虎的经历以及照顾过程中的感受。 课时作业(三) 1．Why did the author bring the tiger cubs home?

D．To let them play with his kids. 解析：细节理解题。根据第一段中的“Globally, a third of Sumatran cubs in zoos don't make it to adulthood, so I decided to give them round­the­clock care at home.”可知，作者把老虎幼崽带回家是为了确保它们的存活。故选A。 课时作业(三) 2．What do the underlined words “get up to mischief” mean in Paragraph 3? A．Behave badly. B．Lose their way. C．Sleep soundly. D．Miss their mom. 解析：词义猜测题。根据画线部分上文“As they grew more ... large room, otherwise they'd ”以及下文“We'd come down in the morning ... like a zoo.”可知，作者不得不把老虎们关在一个大房间里，否则它们就会调皮捣蛋，表现不好。早上下楼时发现它们把房间弄得乱七八糟，看起来像个动物园。由此可推知，画线部分意为“调皮捣蛋”。故选A。 课时作业(三) 3．What did the author think of raising the tiger cubs at home? A．Boring. B．Tiring. C．Costly. D．Risky. 解析：细节理解题。根据倒数第三段中的“Things quickly got very ...

C．They annoyed the neighbours. D．They started fighting each other. 解析：推理判断题。根据倒数第二段中的“When Spot and ... for them to go.(当Spot和Stripe四个月大的时候，它们正在学习如何开门和跳栅栏，我们知道是时候让它们离开了。)”可推知，作者决定把Spot 和Stripe送回动物园是因为它们变得难以控制。故选B。 课时作业(三) Ⅲ　语法填空 The Sanya Nanfan (南繁) Seed Breeding (繁殖) Base, located in south China's Hainan Province, plays a vital role as a seed centre in China. __1__ (unique) blessed with nature's gifts and a wealth of the country's resources, it serves as the dedicated ground __2__ skilled agricultural experts contribute to feeding our nation and addressing global hunger. 课时作业(三) Dr Xiao Feng stands at the forefront of agricultural innovation in Nanfan.

Nevertheless, hope and opportunity persist. The seed of life will always manage __7__ (emerge) through the ground.” 课时作业(三) The term “Nanfan” itself implies to the practice of transplanting summertime crops from northern latitudes to Hainan during its winter.
