for：（1）表目的，向……努力。（2）表示目标，好了。（3）表最终所有权。to：（1）表目的结果、结局。（2）向到。for + noun or to + infinitive To talk about the purpose of an action, we use a for + noun construction or a to + infinitive structure. Compare the following: We stopped off at the Goose for a drink and then we carried on to embassy for dinner. I"m going to Brussels next week for an interview. I hope to work for the UN. Do you want to have a drink at the Goose before we go on to dine with the ambassador? I"ve come to Dublin to attend a seminar and to meet the new members of the faculty. But now I"m leaving for Rome. for + -ing To talk about the purpose of something, we use a for + -ing construction: - These double-strength paracetamols are good for getting rid of headaches. - Are they suitable for backache too? - What are these two knives used for? - This one is for cutting bread and that one is just for slicing meat. What…for? Note that What…for? can be used in questions to talk about the purpose of both actions and things: - You pinched me! What did you do that for? - I wanted to see if you were awake - What are these two buttons for? - The blue one is for gaining access to the main menu and the green one is for quitting teletext. giving reasons and explaining behaviour Note that the same constructions, for + noun and for + -ing, are used with thank, apologise and be / feel sorry: With be / feel sorry a to + infinitive structure is also possible. Compare the following: Thanks for the lift. Thank you for driving me home. South Western trains would like to apologise for the late arrival of this train and for the inconvenience this may cause you. He really should apologise for spitting in his face. That sort of behaviour is unacceptable, even on a football field. I"m sorry to have taken so long with this report. I"m sorry for taking so long with this report. - I feel sorry for the cleaners. - I feel sorry for them too. They"ve got the thankless task of cleaning up all this mess. Note also the way in which the for + -ing construction is used to explain the reasons for the following actions: He was rewarded for handing in the purse. He was criticised for not coming forward as a witness to the accident. He was fined heavily for speeding on the motorway. He was sent to prison for falsifying the accounts. in order (not) to / so as (not) to + infinitive Note that to + infinitive is one of the most common ways of expressing purpose. When we want to be explicit or sound more formal we can also use in order to or so as to. This structures are especially common before negative infinitives, in order not to and so as not to: To get a better job I decided to take a computer course. In order to get a better job I decided to take a computer course. I left home early in order not to be late for the appointment. I left the house early so as not be late for the job interview. 参考文献：http://bbs.englishvod.net/printpage.asp?BoardID=112&ID=234

这个不是个完整的句子，在这里是做定语的。也就是说studied and classified from people"s own speech是定语。所以整句话Simply phonetics studied and classified from people"s own speech只是个有定语的名词。这里的确是被动，本应该是Simply phonetics which were studied and classified from people"s own speech，但是省去which were 也是很普遍的用法。

Categories are specific and personal; they help you impose order.”Categorize 的分类标准比较personal和specific，比如我把书按照我的喜好分类，或者他把杯子按照颜色分类，这些分类都建立在一个分类人自我的标准之上。“Classifying involves sorting phenomena (stuff in general) into known, fixed classes. For example, let"s say someone gave you a 2-page article and asked you to classify the material as Introduction, Main Text, and Summary. You would need to look at the text and make inferences about the material in order to say which class the various sections of the text belonged to. You might infer, for example, that since the first paragraph came first and hinted at the contents of the article, it could be classified as part of the introduction.”而Classify 的分类是一个自然已形成的分类，如上述文字中所说，例如文章开头和结尾的划分，这个分类是文章自身本就包含的，这个标准不是分类者自己设的，而是自然的规则。希望回答对你有帮助。
