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。

| 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。 |
