Contrary to 【小题1】 some people might assume, evidence 【小题2】 (show) that sharks seldom attack humans. There are three types of shark attacks. In the main type, the shark attacks you because it mistakes you 【小题3】 a fish, 【小题4】 when it tastes human flesh, it decides 【小题5】 (give) up and swims away. In the second type, the shark 【小题6】 (push) you with 【小题7】 nose to find out if you are fit to be eaten, and then bites you 【小题8】 it thinks you are. In the third type, the shark waits for you to swim by, and then attacks you all of 【小题9】 sudden. The last two types of attack more often result in the 【小题10】 (die) of humans.

Scientists in Antarctica have made a surprising and welcome 【小题1】(discover)—the world’s largest breeding (繁殖) ground for fish. Researchers from Germany came across the fish while 【小题2】 (make) a map of the seabed of the Antarctic Weddell Sea. They found around 60 million icefish breeding in an area about 240 square kilometers. The research team had been setting down a number of 【小题3】 (camera) to a depth of 530 meters under the Wed-dell Sea for months. “Such a huge breeding area of icefish in the Weddell Sea was 【小题4】(previous) undiscovered, and it is totally attractive,” said Autun Purser, 【小题5】 deep-sea biologist.

The researchers have been exploring the region (区域) hoping 【小题6】 (establish) it as an official Marine Protected Area. They say the seas are a unique habitat that must 【小题7】(preserve). They want to keep fishing and some other scientific research 【小题8】 polluting the waters. A recent University of Cambridge study found that fishing in Antarctica is bringing millions of other species from 1,500 ports around the globe, 【小题9】 are threatening the area’s special eco-system. Autun said, “So far, the remoteness (偏僻) and difficult sea-ice conditions of Antarctica 【小题10】   (protect) it, but we must keep in mind that we should be very careful with oceanic conservation.”

As a nature photographer, I have to brave the wind and the rain, but I still enjoy working outside in the wild. I enjoy observing animals in their 【小题1】 (nature) environment.

Last spring, I followed a path that took me through 【小题2】 dark forest. When I finally stepped out of the trees, the view was breathtaking. An eagle flew over the snow-capped mountains, which 【小题3】 (reflect) in the still lake below. While I was concentrated on photographing this 【小题4】 (amaze) thing, I suddenly had a feeling that I was being watched.【小题5】(slow) and with the camera still held to my eye, I turned …and froze. Only meters away from me was a bear. With water falling off its thick, brown hair, the bear stared back at 【小题6】 (I). Time stood still as the bear and I both waited to see 【小题7】 would move first. My legs started shaking. Somehow I forced my finger 【小题8】 (press) the button. A second later, the bear turned and ran back into the forest. When I recovered 【小题9】 the shock, I looked at my camera. My most frightening but magical experience was now captured forever in a single image.

From time to time I look at the photo as a reminder to show respect to all animals. It is after all we who are the 【小题10】 (visitor) to their world.
