這句話的文法、翻譯

Web2.0 refers to the new generation of web based services and communities characterised by participation, collaboration and sharing of information among users online.
Web2.0指的是新一代的網路(以網路為基準的)服務與社群，其特色為線上使用者共同參與、合作以及分享資訊。
我覺得這邊web based services and communities應該要一起看，指的是以網路為基準的服務與社群。based這邊為pp當adj用。其他例子如：net-based program. 網路為基礎的程式。learner-centered approach，學習者為中心的教學法。
characterised by...則是省略(which are) characterised by....，修飾是前面的web-based services and communities，翻為「的特色為......」。This is a story (which was) told by an old man. 這個故事是老人說的。
希望對你有些幫助嚕!

Web2.0 (主詞) refers (動詞) to the new generation of web based services and communities characterised by participation, collaboration and sharing of information among users online.
1. to the new generation和 of web based services and communities 都是介系詞片語；
2. web based可以分開也可以用-連起來web-based；based是過去分詞當作形容詞使用，修飾web；web based再修飾services and communities
3. characterised by participation, collaboration and sharing...是分詞片語，也是當作形容詞片語使用，修飾services and communities

我來試試看:

The new generation of

1. web based services (過去分詞 based 做形容詞用，形容 services)

2. web based (形容) communities characterized by participation, collaboration and sharing of information among users online.

Communities 的特色是在線者間的參與，合作，與分享資訊。過去分詞片語 characterized by .......... 在形容 communities.


The little boy beaten by the bully is my brother.

Little = 形容詞
beaten by the bully = 過去分詞片語形容 boy.

The boy is my brother.

請指教。

....

Web2.0 提及新一代的以網為基礎的服務和在線上有參與、合作而且在使用者之中的資料分享的特點的社區。

2.0指的是新一代的基於Web的服務和社區的特點是參與，協作和分享信息的用戶在線。
