Antarctic scientists were left【小题1】(astonish) when they discovered a unique creature at the bottom of the ocean, a documentary showed. The icy continent is【小题2】great interest to scientists as it is a totally unspoiled landscape 【小题3】they can study the history of the Earth and the effects of climate change. Thousands of scientists stay there, 【小题4】(dig) below the ice to get a better idea of the icy continent's past.

The team of scientists started a journey through the surrounding waters of Antarctica 【小题5】(discover) some of the most unusual oceanic life known to man. Thankfully, cameras were around to catch one of the most strange moments, when leading scientist Andrew Stewart made an interesting discover about Snailfish (狮子鱼). Snailfish are【小题6】 (poor) understood and Andrew may have found a new species. The sea【小题7】 (have) a wide variety of fish to thrill biologists.

“There may be about 115 species of the snailfish there,” Andrew said, “this is【小题8】 I came to Antarctica, seeing things like this. It’s just beyond 【小题9】(word). We now have the whole families of fish that are found nowhere else in the world except in the Southern Ocean. These are【小题10】(attract) animals.”

Americans love pets. In America, there are more families with pets 【小题1】 those with children. It is common 【小题2】 U.S. homes have some sorts of pets, such as monkeys, snakes and even wolves. But Americans' all-time favorites are cats and dogs, because dogs can offer protection from thieves and unwelcome visitors and cats can help get rid 【小题3】 the home unwanted pests. For keeping pets, there lies a basic American belief: pets have a right to be treated well. In Houston, Texas, dogs can have their dinner 【小题4】(send) to their homes, just like pizza. Pets can even go with 【小题5】 owners on vacation. Besides, there are 75 animal welfare organizations in America 【小题6】 provide care and adoption services for 【小题7】(home) and ill-treated animals. To pay for the high-tech health care, people can buy health insurance 【小题8】 their pets. Pets are as important to American culture as hot dogs and apple pies. So far researchers 【小题9】(discover) that communicating with animals lowers a person's blood pressure. Pets even encourage social relationships. They give their owners an appearance of friendliness, and they provide 【小题10】 good topic of conversation.

A new group of free employees have been added to a French workforce. So far, a theme park in western France 【小题1】 (employ) six birds, more exactly six crows (乌鸦), to collect and deal with garbage-- mainly cigarette ends and other small pieces. The birds take the 【小题2】 (collect) rubbish to special bins where they can receive bird food in exchange 【小题3】 putting away the litter.

Park president Nicolas said, “The purpose of employing the crows is to educate people to take up their social 【小题4】 (responsible). Since the birds are able to do 【小题5】 people are supposed to do, we should do this by ourselves.”

Crows have long been observed for their 【小题6】 (amaze) intelligence. They are one of the 【小题7】 (smart) groups of animals on earth, with remarkable problem solving, tool making, and deductive reasoning skills.

In addition to inspiring humans to pick up trash, the clever crows 【小题8】 are currently working at the park are pretty excited to put their intelligence to work.

“It has become 【小题9】 exciting game for them,” Nicolas says. “They pick up the trash on the ground, and every day they 【小题10】 (reward) for what they have done.”
