11．Sometimesit might/may be helpful to use examples to explain abstract concepts．（helpful）有時候舉例也許有助于解釋抽象的概念．

分析 it might/may be helpful

解答 通過比較英漢句子，漢語句子的主語為"舉例"，對應(yīng)英語句子中的不定式to use example，而此處to use example卻在句后，可以推測此句應(yīng)用it作形式主語，真正的主語在后面--不定式to use example．因此答案為it might/may be helpful．
此處表示可能性，用情態(tài)動詞may/might，helpful表示"有幫助的"．

點評 翻譯時注意情態(tài)動詞might/may的用法，表示也許，可能．

2．It's such a happy-looking library，painted yellow，decorated with palm-tree stickers and sheltered from the Florida sun by its own roof．About the size of a microwave oven，it's pedestrian-friendly，too，waiting for book lovers next to a sidewalk in Palm Beach country Estates，along the northern boundary of Palm Beach Gardens．
It's a library built with love．
A year ago，shortly after Janey Henriksen saw a Brian Williams report about the Little Free Library organization，a Wisconsin-based nonprofit that aims to promote literacy and build a sense of community in a neighborhood by making books freely available，she announced to her family of four，"That's what we're going to do for our spring break!"
Son Austin，now a 10th-grader，didn't see the point of building a library that resembles a mailbox．But Janey insisted，and husband Peter unwillingly got to work．The 51-year-old owner of a ship supply company modified a small wooden house that he'd built years earlier for daughter Abbie's toy horses，and made a door of glass．
After adding the library's final touches （裝點），the family hung a signboard on the front，instructing users to"take a book，return a book，"and making the Henriksen library，now one of several hundred like it nationwide and among more than 2，500 in the world，the only Little Free Library in Palm Beach County．
They stocked it with 20 or so books they'd already read，a mix of science fiction，reference titles，novels and kids'favorites．"I told them，keep in mind that you might not see it again，"said Janey，a stay-at-home mom．
Since then，the collection keeps replenishing （補充） itself，thanks to ongoing donations from borrowers．The library now gets an average of five visits a day．
The project's best payoff，says Peter，are the thank-you notes left behind．"We had no idea in the beginning that it would be so popular．"（317 words）
