When it comes to Australia, we can't help 【小题1】(think) of kangaroos and koalas. Kangaroos are thought to be able to survive in a difficult environment. Often baby kangaroos 【小题2】(find) in their mother's pouch — a kind of pocket — to stay safe and warm. They sleep and drink milk in that 【小题3】(protect) environment until they are about seven or eight months old. Koalas are quite cute, but they are very 【小题4】(sense) creatures who can easily panic because of even small changes in their environment. They spend quite a lot of time eating, sleeping, and hanging onto tree trunks, so 【小题5】(interact) with humans can cause them a lot of stress. Because of this, the government began to make laws 【小题6】 touching koalas. If you want to hold a koala, you have to go to certain licensed zoos 【小题7】 animal experts make sure that the koalas selected for each session are in 【小题8】 good state for human contact.

Australia also has the duck-billed platypus. Do you know what's 【小题9】(real) strange about a platypus? The platypus doesn't use its senses of sight or smell to find food. It has a capacity to find food in the water by using electrical 【小题10】(sensor) in its bill. There are only a small handful of animals in the world that can do that!

Last spring，Fiona Presley，a library assistant from Scottish Highlands came across a surprising phenomenon she would never forget．While taking care of her garden，she【小题1】(spot)a bumblebee(大黄蜂)queen crawling around．What surprised her most was that the animal had no wings，【小题2】made it unable to fly．The bumblebee may have been affected by a virus in wing development．The insect had very slim【小题3】(chance)of survival，but this kind-hearted woman came to the rescue．

Fiona created a beautiful mini garden for the helpless animal and treated it【小题4】some sugar water．When it was sunny．Fiona took it out for【小题5】walk and protected the insect from heavy rain by taking it indoors．Soon enough the beautiful friendship unfolded between【小题6】(they)．Every time Fiona stopped by the garden，her tiny new friend would turn up【小题7】(greet)her．The bee cuddled(依偎)with the woman and seemed to light up when Fiona was holding it in her hands．

The earth bumblebees have an average lifespan of only 18 weeks，   【小题8】Fiona was taking care of her new friend so well that it lived much longer． 【小题9】(sad)，the friendship couldn’t last forever since the bee eventually passed away， 【小题10】 (leave)a beautiful memory to its rescuer．

Aesop’s fable, the town mouse and the country mouse, 【小题1】(concentrate)on the dangers of city living and its advantages. For mice and men alike, as long as those involved, are able to grasp them. It requires an ability to respond successfully 【小题2】 novel problems. So a pair of researchers in Germany have looked 【小题3】(see)whether urban mice are 【小题4】(good)at doing this than rural ones. Their conclusion, just 【小题5】(publish)in Animal Behaviors, is that they are. Valeria Mazza captured 17 mice from farmland and 14 others from 【小题6】(vary)places in central Berlin. They kept these animals in a laboratory for a year and then challenged them with tasks 【小题7】 would yield a reward of food. Tasks included 【小题8】(open)the window of a house made of Lego bricks and yanking out a wad of paper jammed inside a clear plastic tube. Both groups seemed equally eager to participate in the tasks, 【小题9】 the urban mice were more talented at solving the novel ones. It suggested that they were the product of natural select ion acting on 【小题10】(they)city dwelling ancestors.
