During a school-to-life（语境补充词）/school-to-life/ research task, Leo's group received a case with records from several years and places. The first evidence board connected scratch（抓痕、搔）/skrætʃ/, lid（盖子、限制）/lid/, widow（寡妇、孀妇）/'widәu/, deposit（存款、定金）/di'pɒzit/, brake（刹车、阻碍）/breik/, forbid（禁止、不准）/fә'bid/, fur（毛皮）/fә:/, valid（有确实根据的、有法律效力的）/'vælid/, thread（线）/θred/, tourism（观光业、游览）/'tuәrizm/, suite（随员、套房）/swi:t/, straw（稻草、麦管）/strɒ:/, fragile（易碎的、脆的）/'frædʒail/, and warmth（温暖、温情）/wɒ:mθ/. Each item had a date, source, or witness, so the students could check why it mattered. The team has already reviewed the complete plan.
A second folder added graduation（毕业、得学位）/.grædʒu'eiʃәn/, fare（费用、旅客）/fєә/, disc（圆盘、唱片）/disk/, marble（大理石、石弹）/'mɑ:bl/, explicit（详述的、清楚的）/ik'splisit/, disturbing（引起烦恼的、令人不安的）/dis'tә:biŋ/, seminar（研究班、专题讨论会）/'seminɑ:/, swell（增大、隆起的部分）/swel/, biography（传记）/bai'ɒgrәfi/, foreigner（外国人）/ˈfɔrənər/, convenience（方便、便利的事物）/kә'vi:njәns/, delight（高兴、愉快）/di'lait/, till（直到；收银机）/tɪl/, and warehouse（仓库、货栈）/'wєәhaus/. The entries did not all support the same explanation. The group separated direct facts from comments, compared the order of events, and marked information that still needed confirmation（证实、证明）/.kɒnfә'meiʃәn/. The final choice was explained to everyone at the meeting.
The most difficult board included accelerate（加速、促进）/әk'selәreit/, nationwide（全国的、全国范围的）/'neiʃәnwaid/, spit（唾液、唾吐）/spit/, laundry（洗衣店、洗好的衣服）/'lɒ:ndri/, apology（道歉、辩护）/ә'pɒlәdʒi/, bargain（交易、买卖协定）/'bɑ:gin/, unfortunate（不幸的、不合适的）/.ʌn'fɒ:tʃәnit/, anchor（锚）/'æŋkә/, betray（出卖、背叛）/bi'trei/, challenging（挑战的、引起争论的）/'tʃælindʒiŋ/, worm（虫、蠕虫）/wә:m/, beneficial（有益的、受益的）/.beni'fiʃәl/, authentic（可靠的、可信的）/ɒ:'θentik/, and thief（小偷、贼）/θi:f/. Some details looked familiar but carried a different meaning in this case. Mina, who led（lead的过去式和过去分词）/led/ the discussion, asked for clear evidence. The supervisor（管理者、监督者）/.sju:pә'vaizә/ replied, “A useful answer must explain the awkward clue as well as the easy one.”
The final set brought together vague（含糊的、不清楚的）/veig/, scar（疤痕、伤痕）/skɑ:/, inspect（检查、检阅）/in'spekt/, sailor（水手、船员）/'seilә/, suspension（悬挂、暂停）/sә'spenʃәn/, compensate（偿还、补偿）/'kɒmpenseit/, rob（抢夺、抢掠）/rɒb/, dull（使迟钝、使阴暗）/dʌl/, vinegar（醋、尖酸刻薄）/'vinigә/, hopeful（有希望的、怀抱希望的）/'hәupful/, disagreement（不合、争论）/.disә'gri:mәnt/, affection（影响、病）/ә'fekʃәn/, nineteenth（第十九、十九分之一）/.nain'ti:nθ/, and atom（原子、核能）/'ætәm/. The students checked every label, removed two repeated claims, and wrote（写下）/roʊt/ a reason beside each change. If the first method fails, we can try another one. This rule let them correct the record without hiding uncertainty（不确定、不可靠）/.ʌn'sә:tnti/ or blaming a teammate（队友）/'ti:mmeit/.
The team had to meet a deadline（按期完成）/mit ə ˈdɛˌdlaɪn/ and submit an application（提交申请）/səbˈmɪt ən ˌæpləˈkeɪʃən/. Members must be qualified for（有资格胜任）/bi kˈwɑləˌfaɪd fər/ their roles, be capable of（有能力做）/bi ˈkeɪpəbəl əv/ solving problems, and take responsibility for（承担……的责任）/teɪk riˌspɑnsəˈbɪləti fər/ results. They would respond to（回应）/rɪˈspɑnd tɪ/ feedback（反馈、反应）/'fi:dbæk/, take the initiative（采取主动）/teɪk ðə ˌɪˈnɪʃətɪv/, and be willing to（愿意做）/bi ˈwɪlɪŋ tɪ/ revise the plan. The finished report turned a crowded collection into a clear decision. It showed which evidence was strong, which detail needed further checking, and what action should happen next. The group could defend its result because every important word appeared in a real, checkable（语境补充词）/checkable/ context.
