Grammatical particle 把 in Chinese and word order

According to Wikipedia, 42% of world languages follow the subject-verb-object (SVO) order, and 45% follow the SOV order. In a Facebook group, someone said that Chinese is SVO in general, but changes to SOV if the object is a prepositional object. Two examples are given

(1) 我把手机忘了 ("I forgot the cell phone"; very literally "I 把 the cell phone forgot")
(2) 一本书从桌子掉下来 ("a book falls from the table")

I agree that sentence (1) follows the SOV order, as 把 shifts the object 手机 to before the verb 忘. But 把 is not a prepositon. It is a grammatical particle, which has no meaning whatsoever, unlike a preposition. A grammatical particle, e.g. 把 in Chinese and to (as in to do) in English, only serves certain grammatical purposes and if omitted would render the sentence ungrammatical unless other adjustments are made.

On the other hand, sentence (2) is not SOV, because 从桌子 ("from the table") cannot be the object acted upon by the verb 掉 ("fall"). Instead, it is an adverbial clause. In fact, it is wrong to consider any prepositional object (which may be better called prepositional phrase) an object in a sentence. Contrast that with a noun phrase (NP), which bahaves like a noun and can be the subject or object in a sentence, because the last element of a NP is its "head"; "a big boat" still refers to a boat. But in a prepositional object, neither the preposition nor the noun following it can serve as the "head". Omitting either one would make the sentence ungrammatical and meaningless.

Chinese particle 把 moves the object of a sentence to the position before the verb, but no such construct exists in English. This explains why foreigners learning Chinese say 我拿书过来 ("I bring the book over") more than 我把书拿过来.

Translation of a few function words (几个“虚词”的翻译)

* 作时间副词的“最近”：recently（或lately）仅用于过去。一个较常见的错误是将表示“不远将来”的“最近”也译为recently，此时正确的用词是soon、in the near future、甚至now、currently等，或不译，如“我最近在搬家”（Currently I'm moving），“我最近准备买辆车”（I'm thinking of buying a car），“他最近要结婚”（he's going to get married soon / in the near future；但soon更常见）。更多可见http://yong321.freeshell.org/english4chinese/zuijin-is-not-always-recently.html

* “虽然/尽管”：although和though没有词义上的区别，有文章绞尽脑汁找区别，没必要。它们只在文体上有点区别：前者更正式。另外，in spite of和despite也是“虽然”，但后面接名词而不是从句；despite更正式但稍微更不常见。有文章说in spite of和despite后不能接动名词（如in spite of being a manager），但这常见于英语母语者的文章，包括一些较正式的，因此不能算错，也许有些考试会认为错，建议避免。另外，从句用了although或though，主句起首不能用but（对应汉语的“虽然……但是……”），很多中国人和有些南亚、西亚人常犯这种错误；老式英语中会出现主句以yet起首，可以用，尤其在从句较长时，但不能用but。

* “直到”：until和till没有词义上的区别，有文章绞尽脑汁找区别，没必要。它们只在文体上有点区别：前者更正式。英语是世界上十几大语言中唯一对这个词赋以特殊含义的语言：在until/till的时间点后，语句所述状况翻转而不是维持不变，如The scientists had not found a solution to the problem until 1970意味着科学家在1970年终于发现了这个问题的解决方法，而汉语或其他很多（不敢说所有）语言直译对应的语句“直到1970年科学家没有发现这个问题的解决方法”意味着在1970年他们仍然没有发现。更多可见http://yong321.freeshell.org/english4chinese/whats-special-about-english-untiltill.html

* 做时间副词的“很少”：很多人想到seldom，但据Google ngrams图，这个词两百年来使用频率一直在下降，1950年左右被rarely超过。建议用rarely，或not often，如he rarely goes biking / doesn't go biking that often。注意：如果seldom或rarely用于句首（常见于正式文体），句子要倒装（如rarely / seldom did the parliament elicit sharp reactions from...），但如果后面加个逗号停一下就最好不要倒装了，否则听起来有点哽咽。

* 疑问词“第几”：英语（和其他几种语言）中没有。详见http://yong321.freeshell.org/english4chinese/has-no-english-equivalent.html

* “当然”：英语of course或certainly语气一般较强（如"You can swim?", "Of course [I can]"）。汉语“当然”也常用于语气较弱、较缓和的语句中，如“明天每个人都必须到办公室，当然你事先请假了可以不来”(Everybody must come to office tomorrow. But of course you don't have to come if you asked for leave earlier)，用of course对译不错，但如果语气平和点像汉语那样，可不译或译为obviously，或要正式一点说needlesss to say.

* “很”：汉语中的“很”不一定是英语的very，如“他很好”既可以真是说“他非常好”但也可能是“他好”的一种更通顺的变体。更多可见http://yong321.freeshell.org/english4chinese/empty-word-very.html 英语中用very很多的名人首推特朗普，他还喜欢联用如I will very, very probably do it。但大家知道他的manners of speech are unrefined, uncouth, below standard. Don't learn English from him.

* “曾经”：疑问句、否定句中可用ever，如Have you ever been to New York? I've never been（“你曾去过纽约吗？”“我从未/不曾去过”）。但肯定句中的ever就不是“曾经”了，而是老式英语中的“一直”、“永远”，如it was ever thus（总是如此）。“我曾去过纽约”（I've been to New York / I went to New Work before），英译不能用ever，但可用once，如once I had a car accident.

* last与“上个”：last Thursday字面意思是“上个星期四”，但严格地说它指最近过去的星期四；假如今天星期五，它其实指昨天而不是上个星期的星期四。但如果你问英语母语者，他们有时也觉得含混。建议只在不会有混淆的情况下这样用last，如今天是星期天至四的某一天，否则就分别说Thursday last week、the past Thursday（但今天是星期五的话还不如说yesterday）。详见http://yong321.freeshell.org/english4chinese/last-january-vs-january-last-year.html
