At sunrise（日出时）/æt ˈsənˌraɪz/, an abundant（丰富的、充分的）/ә'bʌndәnt/ crowd reached Blue Gulf（海湾、深渊）/gʌlf/ for a beach cleanup（清除、暴利）/'kli:nʌp/. A teen（愤怒、悲哀）/ti:n/ volunteer wore（语境补充词）/wɔr/ a cowboy（牛仔、牛郎）/'kaubɒi/ hat, his buddy（好朋友、伙伴）/'bʌdi/ carried waterproof（防水材料）/'wɒtәpru:f/ gloves, and Kai brought a watertight（不透水的、不漏水的）/'wɒtәtait/ case for data sheets. The breeze（微风、煤屑）/bri:z/ smelled of petroleum（石油）/pә'trәuliәm/ beneath the usual marine air（在通常的海洋气息之下）/bɪˈniθ ðə ˈjuʒəwəl mərˈin ɛr/. Near a sheer（偏转、偏航）/ʃiә/ cliff（悬崖、绝壁）/klif/, sunlight made each wave sparkle（闪耀、火花）/'spɑ:kl/, yet a gray（灰色、暗淡）/grei/ haze（薄雾、阴霾）/heiz/ hung（hang的过去式和过去分词）/hʌŋ/ over the water. Mara, the environmental（语境补充词）/ɪnˌvaɪrənˈmɛnəl/ officer, had boasted（吹牛）/bәust/ that pollution was falling. Then Old Chen（语境补充词）/ʧɛn/ pointed to dead shrimp（虾、小虾）/ʃrimp/ and crab（螃蟹、偏航）/kræb/ beside a fresh spill（溢出、溅出）/spil/.

“Mister（先生）/ˈmɪstər/, your report may say the fish sector（行业；区域）/ˈsɛktər/ is safe, but this tide（潮、潮汐）/taid/ tells another story（说明情况并非如此）/tɛlz əˈnəðər ˈstɔri/.” “Do not dump（垃圾场）/dʌmp/ every mystery（秘密、神秘）/'mistәri/ on the factory. We need evidence before we endanger（危及）/in'deindʒә/ local jobs.” Kai raised an eyebrow（眉毛）/'aibrau/. He happened to overhear（无意中听到、偷听）/.әuvә'hiә/ one team counting trash（垃圾、废物）/træʃ/ by item while another used weight. Such a compound（混合物、复合词）/kәm'paund/ method could crush（压碎、粉碎）/krʌʃ/ honest comparison. Lest（以免、唯恐）/lest/ the disagreement vanish（消失、不见）/'væniʃ/ into rumor, he asked everyone to record the same unit（记录统一单位）/ˈrɛkərd ðə seɪm ˈjunɪt/.

Volunteers began to dispose of waste（处理废弃物）/dɪˈspoʊz əv weɪst/ by category. A zoology（动物学、动物区系）/zәu'ɒlәdʒi/ student found a fossil-shaped（语境补充词）/fossil-shaped/ toy, a pirate（海盗、盗印者）/'paiәrәt/ necklace（项链）/'neklis/, a screw（螺旋、螺杆）/skru:/, a broken（坏掉的、打破的）/'brәukәn/ air-conditioning（空调系统）/ˈɛrkənˌdɪʃənɪŋ/ tube, and a bottle with an unknown（未知物、未知数）/.ʌn'nәun/ ingredient（成分、因素）/in'gri:diәnt/. A hollow（洞、窟窿）/'hɒlәu/ palm（手掌、棕榈）/pɑ:m/ trunk held（hold的过去式和过去分词）/held/ plastic rings that could trap an animal's paw（爪）/pɒ:/. One spouse（配偶）/spauz/ collected glass while the other marked its footprint（足迹）/'futprint/ on the map. The work was tedious（沉闷的、冗长乏味的）/'ti:diәs/, but nobody was dumb（哑的、不说话的）/dʌm/ enough to mix oily（油的、油滑的）/'ɒili/ trash with ordinary litter. Each bag received a clear sector code.

“The two methods produced different totals. Shall we shrug（耸肩）/ʃrʌg/, or publish both（将两种结果都公布）/ˈpəblɪʃ boʊθ/ and explain the gap?” “Publish both. Our reputation is at stake（处于风险之中）/æt steɪk/, and a false boast would be worse.” A nearby laboratory tested whether the water contained a harmful gene-altering（语境补充词）/gene-altering/ compound. It also measured what the outlet might emit（发出、放射）/i'mit/ and checked ozone（新鲜的空气、臭氧）/'әuzәun/ levels. The results did not prove a large petroleum leak, but they did show enough oil to threaten marine（舰队、水兵）/mә'ri:n/ life. Kai insisted that uncertainty（不确定、不可靠）/.ʌn'sә:tnti/ should never become an excuse to dispose（处理、排列）/dis'pәuz/ of inconvenient（不便的、有困难的）/.nkәn'vi:njәnt/ facts.

At sunset（日落、晚年）/'sʌnset/, Mara presented the revised numbers. She explained why the earlier（语境补充词）/ˈərliər/ claim could not simply（语境补充词）/ˈsɪmpli/ be inherited（继承、遗传）/in'herit/ by the new survey. Old Chen did not wed（与...结婚、使结合）/wed/ himself to one theory; he accepted the limits and offered boat records for the next tide. The cleanup removed a tremendous amount of trash, but its larger value was a shared method. Sunshine（阳光、光明）/'sʌnʃain/ alone could not make the gulf pure, and wilderness（荒野、荒地）/'wildәnis/ would not recover through slogans. By admitting the error（承认错误）/ədˈmɪtɪŋ ðə ˈɛrər/, the team protected both community trust and the living shore.
