三、七选五
Some people are so rude. Who sends an e-mail or a text message that just says "Thank you" Who leaves a voice mail message rather than texts you Who asks for a fact easily found on the Internet ①___________
Maybe I'm the rude one for not appreciating life's little courtesies(礼节). But many social norms(规范) just don't make sense to people drowning in digital communication.
Take the thank-you note. Daniel Post Senning, a co-author of Emily Post's Etiquette, asked, "At what point does showing appreciation outweigh the cost "
②___________ Think of how long it takes to listen to one of those messages. In texts, you don't have to declare who you are or even say hello. An e-mail, too, is slower than a text. The worst are those who leave a voice mail and then send an e-mail message to tell you they left a voice mail message.
This isn't the first time technology has changed our manners, ③___________ Alexander Graham Bell, the inventor, suggested that people say, "Ahoy! "Finally, hello won out, and the victory sped up the greeting's use in face-to-face communication.
In the age of the smartphone, there is no reason to ask once-acceptable questions about: the weather forecast, a business's phone number, or directions to a house, a restaurant, or an office, which can be easily found on a digital map. ④___________ And when you answer, they respond with a thank-you e-mail.
How to handle these differing standards Easy: Consider your audience. Some people, especially older ones, appreciate a thank-you message. ⑤___________ In traditional societies, the young learn from the old. But in modern societies, the old can also learn from the young. Here's hoping that politeness never goes out of fashion but that time-wasting forms of communication do.
A. Then there is voice mail.
B. Others, like me, want no reply.
C. But people still ask these things.
D. Don't these people realize that they're wasting your time
E. Won't new technology bring about changes in our daily life
F. Face-to-face communication makes comprehension much easier.
G. When the telephone was invented, people didn't know how to greet a caller.

四、答案：Organized ; volunteers ; were collected ; that/which; are provided; to reach; unfortunately ; floating ; a; of
解析：①考查非谓语动词。此处为过去分词短语作状语。organize与逻辑主语free trips之间为被动关系。
②考查名词。此处指“在一千个皮艇志愿者的帮助之下”,由空前a thousand可知,此处应使用复数形式。
③考查时态和语态。根据前文和空后的that year可知应用一般过去时,three tons of trash与collect之间为被动关系,故为一般过去时的被动语态。
④考查定语从句。此处为限制性定语从句,先行词为kayak,关系词在从句中作主语,故填that/which。
⑤考查时态和语态。此处描述的是一般性情况,应使用一般现在时;主语Life jackets and equipment是复数概念,且与provide为逻辑上的被动关系,应用被动语态。
⑥考查非谓语动词。此处是be hard to do sth.,意为“做某事很困难”。在please、glad、happy、difficult、hard、easy等形容词后作状语,只能用动词不定式,用主动形式表示被动含义。
⑦考查副词。句意:在丹麦,人们喜欢在运河上闲逛,但不幸的是,他们会看到垃圾漂过……。分析句子可知,设空处修饰but后面的整个句子,应用副词形式,根据句意可知,看到垃圾漂过十分不幸运,故填unfortunately。
⑧考查非谓语动词。句意:在丹麦,人们喜欢在运河上闲逛,但不幸的是,他们会看到垃圾漂过……。此处为现在分词作宾补,表示“正在漂浮着”。
⑨ 考查冠词。此处为make a difference的搭配,意为“有影响,有作用”。
⑩考查介词。此处take advantage of意为“利用”。
