首先要明确的是，网友的三个句子都是对的：正：The horse is a useful animal.正：Horses are useful animals.正：A horse is a useful animal.网友的问题涉及不定冠词的类指用法，即不定冠词可用于表类指——从个体的维度来看待整体，即从该类中随便找一个具有代表性的个体，它都具有整个类属的基本特点。此用法也可以改用定冠词，或不用冠词而直接用名词复数（虽然它们在语体和用法上略有差别，但意思是一样），所以上面三句都是对的。但是注意，不定冠词表类指，只限于从个体的维度来看待整体（即从该类中随便找一个具有代表性的个体，它都具有整个类属的基本特点），我们是不能用它来概括整个类属的，比如下面的句子就是错误的：误：A whale is in danger of becoming extinct. (可考虑改用定冠词)误：A telephone was invented in 1876. (可考虑改用定冠词)

PEU的原意并不是说 everybody 一定不能用 his or her 来回指，而是说在某些特定的语境中不能用它，即在强调整体或者说强调所有人时不宜用它（这种强调要注意在具体境中去体会，没有固定的规则去死记）。When everybody had finished eating, the waiters took away their plates.这句话的语境是：人们在餐馆吃饭，当每个人都吃完了的时候，服务员肯定是把他们所有人的盘子都收走，即这是在整体或者说强调所有人，所以宜用 their。比如下面的句子，都完全可以用 his or her（虽然这个说法比较正式或繁琐）：Everybody raised his or her voice.Everybody has to pay his or her taxes.Everybody applauded his or her own son. Everyone should bring his or her own lunch.Everyone brought his or her partner to the party. Everyone is special in his or her own way. Everyone has his or her own ideas about what is important.

有些人认为，表语形容词通常不能直接用于 seem 之后作表语，应在这些形容词前加to be，比如认为应该说seem to be afraid (asleep, awake)，但不说 seem afraid (asleep, awake)。但事实上，人们在实际使用中并不完全遵守，而且不少主流的语法著作也收录了这种用法。

go back to do sth与go back to doing sth意思不同，用法也不同：go back to do sth中的不定式是目的状语，指“回去的目的是为了做某事”。如：He went back to get some money. 他回去取一些钱。He went back to visit his old friends. 他回去看望老朋友。He went back to tell her the news. 他回去把这个消息告诉她。go back to doing sth中的to介词，所以后接动名词，指“回到以前做某事的状态”。如：I wouldn’t go back to living in the city. 我不会回城里居住的。It’s a pity he’s gone back to smoking again. 他又开始吸起烟来了，真遗憾。Why don’t you go back to doing what you do best? 你为什么不回头去做你最擅长的事？ 网友的句子：After studying agriculture, medicine, and fisheries in college, John went back to observing nature and asking questions.在大学学习了农业、医学和渔业之后，约翰又继续去观察自然和并提出问题。要想理解这个句子，网友需要联系第一段的内容来看：When John Todd was a child, he loved to explore the woods around his house, observing how nature solved problems. A dirty stream, for example, often became clear after flowing through plants and along rocks where tiny creatures lived. When he got older, John started to wonder if this process could be used to clean up the messes people were making. After studying agriculture, medicine, and fisheries in college, John went back to observing nature and asking questions. Why can certain plants trap harmful bacteria? Which kinds of fish can eat cancer-causing chemicals? With the right combination of animals and plants, he figured, maybe he could clean up waste the way nature did. He decided to build what he would later call an eco-machine. 文章第一段说的是：约翰·托德小时候喜欢探索房子周围的树林，观察大自然是如何解决问题的…… 所以文章第二段才说约翰大学毕业之后“又继续去观察自然”（John went back to observing nature）。

同意胡老师的看法，我也觉得这个of改为for更合适些。当然也可能会有网友从网上找到反例来证明北京卷的说法是对的。但对于针对学生用法的层面来说，这个句子肯定将of改为for更合适些。本来cure后面接介词for或of都可以，但用法是有区别的：cure若表示治疗的药物或治疗的方法，其后通常接介词for；cure若表示治疗的动作行为或过程（疗程），则其后通常接介词of。比较：the cure for an illness 治好某疾病的方法the cure of an illness 治好某疾病的过程再比较：The cure of his illness took six months. 治好他的病花了半年时间。We are trying to find a cure for his illness. 我们在想办法找到治好他的病的方法。再回到2022年北京卷的这个句子：Patience is a cure of anxiety.从句意来看，这应该是指治疗的方法，而不是指治疗的动作或行为，所以改为for可能更合适些。查了一下2022年的北京卷，网友的句子不是出自北京卷的阅读材料，而是出自命题者在阅读材料后面的命题选项，也就是说，这个句子是命题者自己编的，所以这也可能是命题者的疏忽。个人看法，仅供参考！不妥之处，请大家指正！

这位朋友大意了。你的老师说，allow后面要接动名词，是指接动名词作宾语吧。但这里的不定式to make decisions...是宾语吗？显然不是！它是主语补语。比较：allow doing sth（动名词作宾语）allow sb to do sth（不定式作宾补）be allowed to do sth（allow用于被动语态，后面的不定式作主补）你的句子就是 allow 的被动语态，不定式作主补：He alone was allowed to make decisions on foreign policy. 只有他被准许就外交政策做出决定。

前面两位老师的翻译都很好。我试图换个角度来试试。比如也可以将 Society Girl 翻译成《千金小姐》。又如：society woman 可以考虑翻译成“贵妇人”“上流社会的女子”等。仅供参考！请看《柯林斯英英词典第8版》在society词条相关解释（重点查看第6条解释和例证）：society [səˈsaɪətɪ] n, pl -ties 1. the totality of social relationships among organized groups of human beings or animals 2. a system of human organizations generating distinctive cultural patterns and institutions and usually providing protection, security, continuity, and a national identity for its members 3. such a system with reference to its mode of social and economic organization or its dominant class middle-class society 4. those with whom one has companionship 5. an organized group of people associated for some specific purpose or on account of some common interest a learned society 6. a) the privileged class of people in a community, esp as considered superior or fashionable b) (as modifier) a society woman 7. the social life and intercourse of such people to enter society as a debutante 8. companionship; the fact or state of being together with someone else I enjoy her society.9. ecology a small community of plants within a larger association

a black hole 的字面意思是“黑洞”。《剑桥高阶英汉双解词典》对 black hole 的解释是：a region in space where gravity is so strong that nothing, not even light, can escape 黑洞（宇宙中包括光线在内的任何东西都无法逃逸的强引力区域），也可表示 an imaginary place in which things are lost （想像中事物消失的）黑洞。如：Anything that crosses the boundary of a black hole cannot get back. 任何物质只要跨越黑洞的界线就再也无法出来。The dark star in Nova Muscae 1991 is a black hole rather than a neutron star. 在1991年苍蝇座中的暗星其实是一个黑洞而非中子星。Radio signals received from the galaxy’s centre back up the black hole theory. 从该星系中心收到的无线电信号证实了黑洞理论。但 black hole 也可用于比喻义，表示“绝望”“糟糕的境地”“绝望的境地”等。网友句子中的 black hole 就属于比喻义：By not facing my fears, I had created a black hole that would be difficult to climb out of. 由于不敢面对恐惧，我让自己陷入了一种绝望的境地，并很难从中解脱出来。
