Sentence meaning This was pulled from a passage called: 未来的房屋 (I translate this as "House of the Future"): 还有一种很有趣的房屋叫“吃不完”。为什么要叫作“吃不完”呢？因为里面的东西吃完了还有。 It's really the last sentence that's giving me trouble. I interpret this as saying "There is also an interesting house called 'can't finish eating.' Why is it called 'can't finish eating?' Because the food inside the house has already been eaten." Is that right? I feel like I'm missing something. What is the purpose of the 还有 at the end?

Full verbs vs. Partial verbs In the following sentence I have several questions. If you can answer any of these that would be most appreciated 我们经常互相帮助,遇到难题时我们互相帮着想办法。 1) Why do you need need the full verb form 帮助 in the first part of the sentence but you can shorten it to simply 帮 in the second part? I realize there is also an aspect particle in the second part 着 but that still doesn't explain why you don't have to write 帮助着. 2) In this case is 帮助 an instance of a result complement indicating that you succeeded in helping? Words like 看见， 听到， 走到 ， and 抓住 are all result compliments wondering if 帮助 is too. 3) Does that last part of the sentence (遇到难题时我们互相帮着想办法想办法) translate roughly to "When we encounter difficult problems, we help each other think of what to do"? 4) Why do you need the ongoing-action aspect particle 着? If the sentence is saying what I wrote in number 3), that's not an ongoing action, it's a an action which occurs at certain times.

When best to use 对 correctly I understand 对 can link a subject, object, and a verb, is it always important to use it in these situations?
