The population of the milu around China’s Poyang Lake     1    (grow) from 47 to 55 since a group of the rare deer was released (释放) there about a year ago. Yang Qibo, who is in charge of Poyang County’s wildlife protection station, told the public that they had recorded     2     birth of 8 deer over the past year. Last April,     3    (improve) biodiversity in the local wetland ecosystem, China released 47 deer into the wild around Poyang Lake, the country's largest freshwater lake. The species’ sudden     4    (disappear) occurred around 1,000 years ago in this area. Local officials said the deer adapted well to the new environment and coexisted     5    (peaceful) with local villagers. Whenever a deer     6    (spot), villagers would always report it to wildlife authorities. There were some cases     7     the villagers’ crops were damaged by deer, but they usually chose to drive the deer away instead of hurting them. The milu, also known as Pere David’s deer, is native to China. In China it bears the     8    (humor) name “sibuxiang” or “like none of the four” for its unique features. The wetland deer species is put     9     A-level state protection after overhunting and habitat (栖息地) loss led to its nearly     10    (die) out in the early 20th century. Now about 6,700 deer live across the country, including 1,500 in the wild.

There’s just a 1-in-3,700,000 chance that a person will be killed by     1     shark, but the fear is still enough to have swimmers worrying about     2     (be) seen as prey (捕获物). Now, new research supports the long-standing theory     3     when great whites go in for a bite, it’s a case of “mistaken identity”.

A team of biologists     4     (compare) videos of seals swimming with those of humans swimming. They then edited the clips to simulate a great white’s vision and found that from the ocean inhabitant’s point     5     view, humans do indeed have a strong resemblance to seals.

“Usually, great white sharks     6     (regard) as ‘mindless killers’ and fond of human flesh. However, this does not seem to be the case; we just look like     7     (they) food,” Laura Ryan, lead author of the study, told Live Science.

“They eat seals every day and bites on people are     8     (extreme) rare,” said Catherine MacDonald, a marine scientist at the University of Miami. “So if they’re not solving the problem visually, then how do we think they’re solving it?     9     (hit) the right targets, sharks could be relying on other senses, like the scent. If that’s the case,     10     (addition) studies on how great whites use those senses could help prevent further attacks.”
