1 . A self-driving Uber vehicle struck and killed a pedestrian in a late-night accident in Tempe, Arizona, police said on Monday. The accident is believed to be the first pedestrian death involving the technology of autonomous vehicles.

The gray SUV had an operator in the driver’s seat and was traveling at about 40 miles per hour in autonomous mode when it struck a woman who was walking across the street late Sunday night, Tempe police said. The pedestrian was rushed to a hospital, where she was pronounced dead from her injuries.

“The City of Tempe has been supportive of autonomous vehicle testing because of the innovation and promise that the technology may offer in many areas, including transportation options for disabled residents and seniors,” Tempe Mayor, Mitchell said in the statement. “Testing must occur safely. All indications we have had in the past show that traffic laws are being obeyed by the companies testing here. Our city leadership and Tempe police will pursue any and all answers to what happened in order to ensure safety moving forward.”

Self-driving cars have been praised by technology companies as the wave of the future. Autonomous cars are already being in more than 30 cities around the world, with companies investing more than $80 billion into research and development.

“Everyone recognized that someone was going to die in a crash involving an autonomous vehicle eventually,” Bryant Walker Smith, a law professor at the University of South Carolina who studies risks in automated driving systems, told NBC News. “As good as that technology tries to be, mistakes can happen, or it may be one of the small fraction of crashes. I just think everybody kind of hoped that one wouldn’t come this soon.”

Smith added that because federal and state agencies don’t have the resources to monitor individual vehicles, the responsibility for safety falls on the individual companies running the technology.

The National Transportation Safety Board announced that a four-person team has been sent to Tempe to investigate the crash.

3 . 阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。

Sean turned to look at his father, who was standing confidently on his new sailboat. Sean hated it that he couldn’t remember all of the sailing terms (术语) and skills his dad taught him. However, he pushed himself to ask, expecting his father’s response. “Which way are we turning?” “We’re coming about” his father said firmly. “That means we are turning into the wild. That way.” His father said, pointing to the right side of the boat. “Time for you to make a bowline knot (单套结)!”

Sean reached for a rope and tried his best to make one. His father had taught him the skill dozens of times, which could not only help moor (停泊) the boat but also save everyone in emergency. After practising several times, he finally knew how to do this correctly and quickly. He looked back at his father, hoping for a praise. But his dad was looking up at the sail (帆), not at him. He untied the knot and dropped the rope under the seat, filled with a sense of loss.

He looked up at the sky. Dark clouds gathered overhead and the wind began blowing. “Hey, Sean, come and take the wheel for a minute!” His father ordered. Sean didn’t want to, not did he want to see that disappointing look on his father’s face. “Uh, year!” Sean locked the sail in place and went to keep the wheel.

“Just keep her going straight. I’m going to check something.” Sean held the wheel tightly. Suddenly, the wind changed direction. The boat shook sharply and even tipped (倾斜) to one side. “Dad!” he called, but no response. He didn’t see him anywhere on the sailboat. Just then, the water became calm a little. Sean caught the chance to look the wheel quickly. He looked out at the huge crashing waves. Then he saw it--- a flash of a figure.

注意：续写词数应为150左右。

Much to his surprise, the figure in the water was his dad!
