At the outset of（在……开始时）/æt ðə ˈaʊtˌsɛt əv/ the Riverlight handover（转移、转换）/'hændәuvә/, project manager Ava placed a memorandum（备忘录、便笺）/.memә'rændәm/ at the center of the table in the city lobby（大厅、休息室）/'lɒbi/. The prime（首要的；最好的）/praɪm/ task was to assemble（集合、收集）/ә'sembl/ one accountable（负有责任的、可说明的）/ә'kauntәbl/ plan before engineer Noah left headquarters（总部、司令部）/hed'kwɒ:tәz/. The project linked a public fountain to an app. Lights would span（指距、全长）/spæn/ the pool while a horn（角、角质）/hɒ:n/ marked each show. Other effects included a bang（重击、突然巨响）/bæŋ/ and a splash（飞溅、污点）/splæʃ/. Client counterpart（副本、复本）/'kauntәpɑ:t/ Priya wanted a swift（褐雨燕、快速爬行的小蜥蜴）/swift/ launch, but no one could locate a final owner for safety oversight（勘漏、失察）/'әuvәsait/.

Noah had been asked to oversee（向下看、了望）/.әuvә'si:/ code. Yet a commission（委员会；委托；佣金）/kəˈmɪʃən/ from the city bureau（局、司）/'bjuәrәu/ had also told（语境补充词）/toʊld/ him to supervise（监督、管理）/'sju:pәvaiz/ sound. In accordance with（按照）/ɪn əˈkɔrdəns wɪθ/ the contract, the team had to comply with（遵守）/kəmˈplaɪ wɪθ/ noise rules and conform（使一致、使遵守）/kәn'fɒ:m/ to access standards. Ava began to coordinate（同等的人(或物)、坐标）/kәu'ɒ:dineit/ the records, delegate（代表）/'deligeit/ each task, and consolidate（巩固、使联合）/kәn'sɒlideit/ duplicate（副本、复本）/'dju:plikeit/ files. She found an old-fashioned（老式的；过时的）/ˌoʊldˈfæʃənd/ chart that attributed（属性、标志）/ә'tribju:t/ everything to “engineering.” That superficial（表面的、肤浅的）/.sju:pә'fiʃәl/ label could not authorize（授权、批准）/'ɒ:θәraiz/ release or explain who would administer（管理、料理）/әd'ministә/ later repairs.

Priya said, “I am（语境补充词）/æm/ uneasy（心神不安的、不自在的）/.ʌn'i:zi/ because every delay is invariably（不变化地、恒定地）/in'vєәriәbli/ described as someone else's problem.” Noah replied, “I resent（愤恨、憎恶）/ri'zent/ that rumor（谣言、传闻）/'ru:mә/; give me a clear ratio（比、比率）/'reiʃәu/ of risk to time, and I will name what I can own.” Ava said, “Let us slow down（放慢；冷静下来）/sloʊ daʊn/, identify each knot（结、群）/nɒt/, and implement（工具、器具）/'implimәnt/ only what the evidence supports.”

They reviewed strange test failures. A loose strap（带、皮带）/stræp/ had let a cable whip（鞭子、抽打）/hwip/ the water; a visitor's dog tried to lick（舔、少许）/lik/ a sensor（检测器）/'sensә/; a child began to crawl（爬行、匍匐而行）/krɒ:l/ under a barrier. One animation（活泼、生气）/.æni'meiʃәn/ seemed to disintegrate（(使)分解、(使)碎裂）/dis'intigreit/, while another tossed（投掷、抛）/tɒs/ a bright shape across the screen. In haste（匆忙地）/ɪn heɪst/, a tester had exaggerated（夸大、夸张）/ig'zædʒәreit/ the fright（惊吓）/frait/ and hinted（暗示、提示）/hint/ that the whole structure might collapse. Ava knew（语境补充词）/nu/ how to keep a firm grip（牢牢控制）/kip ə fərm grɪp/ on the review. She subtracted（减去、扣掉）/sәb'trækt/ repeated incidents and showed that the true risk was immense（极广大的、无边的）/i'mens/ only during strong wind. A stale（使变旧、走味）/steil/ seal, not the core design, caused the leak.

The team initiated（入会、开始）/i'niʃieit/ a conscientious（有责任心的、负责的）/.kɒnʃi'enʃәs/ handover. Noah accepted software, Priya agreed to be responsible for public notices（负责公共通知）/bi riˈspɑnsəbəl fər ˈpəblɪk ˈnoʊtɪsɪz/, and Ava retained overall oversight. They would exploit（开发、利用）/'eksplɒit/ no loophole and give no one a mere hint of ownership. The schedule included time for a short nap（小睡、稍睡）/næp/ after overnight tests, but vigor（精力、活力）/'vigә/ mattered less than accurate judgement（判定、审定）/'dʒʌdʒmәnt/. Accordingly（相应地、因此）/ә'kɒ:diŋli/, Ava chose to replace rumor with signed evidence（用签字证据取代谣言）/ˌriˈpleɪs ˈrumər wɪθ saɪnd ˈɛvədəns/ and attached each cable, horn, and safety barrier to a named person. The client no longer needed to plead（辩护、恳求）/pli:d/, threaten, or crack a whip; a practical responsibility map made the launch possible.
