怎么读这份表

  • 选词范围:只收本轮材料里真实出现过的英文——官方原文术语 + 前八页讲解里反复出现、读懂会卡住的词。中学词汇、只出现一次且无理解障碍的不收;不凭空扩表。
  • 定位:¶段落号 回译文找、原文语境 回 sources 找。原文句子按官方网页原样摘录,不替它修字。
  • 中文列是词义;提示列是整理者补充的用法或辨析,不是原作者定义。
  • 生句单独一节,给语法结构 + 直译/意译,与生词一样同步入库。

F. 生句(11 条,与生词一起入库)

# 原句 语法 译文
S1 A wheeled Atlas isn't a product. It's a research testbed. 两个短句对比;wheeled 是过去分词作形容词 装轮子的 Atlas 不是一个产品,它是一台研究试验台。
S2 If the simulation used for training assumes the motors are over-idealized, the policy can end up learning things the real hardware can't actually do. If 条件从句 + 过去分词短语 used for training 作后置定语 + 省略关系代词的定语从句 (that) the real hardware can't...;end up doing 表「最终落得」 如果训练用的仿真把电机假定得过于理想,策略最后可能学到真硬件根本做不到的东西。
S3 Just as important was knowing which approximations were safe to make and which ones the policy would learn to exploit. 表语前置引起倒装(正常语序 Knowing... was just as important)+ 两个并列的宾语从句 同样重要的是判断哪些近似是安全的、哪些会被策略学会钻空子。
S4 Because Atlas was designed from the start to be produced at high volume and to be easy to service, the retrofit was about as involved as swapping a wheel on a bicycle. Because 原因从句 + 两个并列不定式被动 + as ... as 同级比较 因为 Atlas 从一开始就按可大批量生产、易维护设计,这次改装的工作量差不多等于给自行车换个轮子。
S5 A good share of that work was unglamorous but important: checking that ..., running characterization experiments, and tuning the simulated motor model to match what we measured on the robot. 冒号后三个动名词并列作同位语;match 后接 what 引导的宾语从句 这份工作里相当一部分不光鲜但很重要:核对参数、跑特性标定实验、把仿真电机模型调到与真机实测吻合。
S6 The goal was for the policy to train against the same "plant" it would meet on the hardware. for sb./sth. to do 不定式复合结构作表语;plant 后省略关系代词 目标是让策略训练时面对的「被控对象」,和它在硬件上遇到的是同一个。
S7 Working across these layers, I found that the robot's limits usually lived in the space between them, in how the motors, the low-level control, and the training all play off one another. 现在分词短语作状语 + that 宾语从句 + in how 引导的介词宾语从句具体化 "the space" 跨这些层工作之后,我发现机器人的极限通常住在层与层之间:在电机、底层控制、训练三者如何互相影响里。
S8 I deliberately looked for clips with a lot of foot sliding, since that seemed like exactly where wheels would make things interesting. since 引导原因从句 + where 引导表语从句 我专门挑了脚打滑多的片段,因为那看起来正是轮子会让事情变有意思的地方。
S9 The 360-degree jump was actually low-risk, despite looking like a high-energy feat. despite + 动名词短语作让步状语 360° 转体跳看着像高能量动作,其实风险很低。
S10 Give the policy wheels, and it figures out how to use them. 祈使句 + and + 陈述句(= 条件句「只要……就……」)+ how to 不定式作宾语 给策略装上轮子,它自己就琢磨出该怎么用。
S11 Before Atlas rolled across a real floor, it rolled across millions of simulated ones. Before 时间从句 + ones 替代前面名词避免重复;rolled 一词两用形成对照 在 Atlas 滚过真实地板之前,它先滚过了上百万块仿真地板。
