When I was in college, a white cat often showed up on our campus. It was clear 【小题1】 he was a stray (流浪的) cat because he looked thin and weak. Students would play with him after class and feed him all kinds of food. The school didn’t say anything about the cat for 【小题2】 long time.

But one day, we 【小题3】 (tell) that one of our fellow students had an infectious disease and that the cat was 【小题4】 (possible) the source. After that, we were not allowed to touch any stray 【小题5】 (animal) on campus. The school started to make efforts to keep animals 【小题6】 campus as well.

Since we were not allowed to feed the white cat, it was hard for him to find food on the street. He 【小题7】 (become) weak and skinny. But while the rest of us ignored the cat, a security guard at our school decided to take on the 【小题8】 (responsible) of caring for him. He took the cat to a vet for a health check. He then went to a nearby supermarket and bought food for the cat, as well as a small bed for him to sleep in. He made sure the cat was healthy and 【小题9】 (comfort).

It might seem like a small effort to some people. 【小题10】 this man risked his job - his only source of income - just to feed a tiny cat who no one else cared for. It was a very heartwarming thing to see.

Giant pandas are seen as living proof 【小题1】 conservation works, the numbers of which in the wild are recovering after years of decline.

The distinctive black and white bear 【小题2】 （regard ）as an “umbrella species”. That means protecting the mountain forests 【小题3】 they live has been good for many other animals, including birds and small animals that mainly feed on meat.

Yet, according to a new study published in the journal Nature Ecology Evolution, it’s a 【小题4】 （complete）different story for larger predators（食肉动物） such as leopards and wolves. Asian wild dogs have disappeared from 95% of areas set up 【小题5】 （protect） pandas in the 1960s. Leopards, wolves and snow leopards have also been found much 【小题6】 （few） than before. Scientists in China say these four predators are being driven 【小题7】 near extinction by illegal hunting and destruction of 【小题8】 （they） habitat.

Conservation efforts have often been based on protecting specific species such as the panda. But experts argue for a new approach that 【小题9】 （aim） to protect whole ecosystems, rather than focusing on a single species. Thus, the   【小题10】 （disappear） of larger predators will hopefully slow down.

When I called【小题1】my mother, she told me snakes came near the house now and then. Here was a chance for me to distinguish 【小题2】(my) by inventing something merciful that would seize snakes but not harm them. I tried to find some products【小题3】might help me, but there only seemed to be【小题4】(powder) designed to kill snakes. I set about【小题5】(research) the habits of snakes. Prepared with some research findings, I【小题6】 (decide) on three possible approaches. I chose the most practical one to cool the snakes with frozen bowl and ice-cream so that they would become sleepy【小题7】could be easily caught. My third attempt was 【小题8】(success). I carried in my hand a small net in the expectation that the snakes would bite again. But 【小题9】 (monitor) carefully, the snakes proved to be no trouble. I collected the passive snakes and the next day and【小题10】(merry) released them all back into the wild.
