And on Aug. 21, the Utah Division of Wildlife Resources (DWR) shared a video of them doing just that. In the video, the small fish erupted from the bottom of an airplane into the water.It might seem like the fall from the plane would result in a fatal (致命的) end for the fish, but the Utah DWR explained that at least 95 percent of the fish are expected to survive. “That's because the young fish are so small — only 1 to 3 inches (2.5 to 7.6 centimetres) long — that they fall to the water like leaves，” said Phil Tuttle the outreach manager for the southern region office of the Utah DWR.“The pilot lies just above the tree line to drop the fish, or as low as possible while considering other natural barriers like cliffs and mountains，” Tuttle told Live Science in an email. Years of netting surveys (collecting fish in a net and counting them) and decades of recreational fishing suggest the fish do all right after the drop. Utah DWR staff members have also conducted netting surveys within minutes of a drop to check survival rates.More than 200 of Utah's remote mountain lakes are stocked every year using this aerial (航空) fish­drop method. The lakes are often far from any road and can take a long time to reach by land, which makes land transports more stressful for the fish compared with aerial transports.Most of the stocked lakes would be fishless, were it not for the DWR's stocking efforts. The DWR primarily stocks lakes with sterile fish so they can control the population and minimise (减至最小) their impact on native wildlife species. The most common species to make these lights are various species of trout (鲑鱼)．1. What is the possible reason for the high survival rate of the fish?A. Their thick skin.B. Their small size.C. Their strong body.D. Their good appetite.2. How can Utah DWR get to know the survival rates of the fish?A. By doing netting surveys.B. By counting natural barriers.C. By recording the drop height.D. By holding fishing.3. Why do Wildlife officials in Utah drop fish from airplanes?A. It's the cheapest way available.B. The lakes are unreachable by land.C. It's better for the fish than land transports.D. They want to train the fish in a special way.4. What does the underlined word “sterile” in the last paragraph probably mean?A. Fierce and aggressive.B. Unable to produce babies.C. Completely free from bacteria.D. Energetic and good at jumping.【语篇解读】本文是一篇新闻报道。文章介绍了犹他州的野生动物官员自1956年起就通过从飞机上放鱼来为偏远的山区湖泊放养鱼类，犹他州野生动物资源局分享了他们这样做的视频。1.

The dark night air was cold and a little wet, and the street lamp gave little light. Frank was anxious to get home and his footsteps rang loudly on the silent night.When he reached the middle of the bridge, he thought he could hear someone coming near behind him. He looked back but could see no one. However, the sound continued and Frank began to walk more quickly. Then he slowed down again, thinking there was nothing to fear in a town as quiet as this.Just then, he heard short, quick steps closely behind him. By the time he reached the other side of the bridge, he could almost feel someone at his heels. He turned round and there stood a man in a large coat. A hat was pulled down over his eyes and very little of his face could be seen.Frank said something about the weather in an effort to be friendly. The man did not answer but asked roughly where Oakfield House was. Frank pointed to a big house in the distance and the stranger continued his way.Then Frank wondered why the stranger had wanted to find Oakfield House at such an hour. He knew that the people who lived there were very rich. Almost without realising what he was doing, he began following the stranger quickly.The man was soon outside the house and Frank saw him look up at the windows. A light was still on and the man waited until it went out. When about half an hour had passed, Frank saw him climb noiselessly over the wall and heard him drop on the ground at the other side.注意：续写词数应为150左右。Now Frank knew what the man wanted to do. ___________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________Frank couldn't just stand in the dark and wait. ___________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________【参考范文】Now Frank knew what the man wanted to do. Everyone knew that Oakfield House was filled with artwork worth millions of dollars. It was clear to Frank that the family inside was in danger. Would the man have a weapon? Would he be strong enough to overpower him before he could harm the people inside? Frank's heart was racing with fear. He reached for his cellphone to call the police, but found it out of power. If only he had charged his phone before leaving the office, but it was too late.Frank couldn't just stand in the dark and wait. He had to do something, even if it meant risking his own life. At his feet he silently found several good­sized stones, and he threw them with all his strength right at the windows of the house. The clatter woke up the people inside the house and a light came on upstairs. The man froze, not quite knowing what had just happened. Lights came on everywhere in the house and within a minute the night was filled with sounds of police sirens screaming towards Oakfield House.
