曹老师，您这里说的can表示客观条件的许可，是不是就是理论上的可能性？谢谢

是的。

曹老师： They also include such treatments as acupuncture (using needles to treat illnesses) and aromatherapy, which as the name suggests, uses types of smell (aroma) as therapy. 1) 这个which as the name suggests 怎么理解？多了一个which吗？ In fact, several British soccer players have used acupuncture to treat injuries that, in the past, would have required surgery, or that they would have had to put up with. 2) 这句话中的2个would have done 是虚拟语气吗？有同学说是推测用法，仔细体会，也是对的呀。我感觉2种理解似乎都可以啊？怎么回事呢？

1 as分句是定语从句中的方式状语，插入到定语从句的主语which和谓语动词uses之间了。2 这是定语从句中的虚拟语气。这里隐含了一个虚拟条件，即要是不是现在，而是在过去，本会如何如何。事实是现在就是现在，而不是过去，所以从句用虚拟语气。

曹老师： 1）The reading shows problems with driving in cities. 这里 problems with driving 正确吗？ 没看到过problems with doing 这种结构？ 2）Centre Ville is the result of a 25-year redevelopment plan for the waterfront city center. 这个for the waterfront city center. 是定语吧？

1 不要随意质疑，这是不好的阅读习惯。driving在此是名词。朗文：problem with： I’ve been having a few problems with my car. 2 是的。
