9．For centuries，mankind and dogs have suffered from a communication failure．We can tell dogs what we want them to do and sometimes they comply，but we've always struggled when it comes to understanding the true meaning of their barks and whimpers．There is exciting news now-a dog translator has been invented to help you communicate with your furry friend．
Researchers at North Carolina State University have fashioned some kind of miracle dog translator body harness（束腰带）．What's special about it is that it doesn't just rely on the dog's vocalizations to interpret what Fido is banging on about．
Oh no-this miracle harness reads and interprets the ordinary dogs'body language as well，giving us a full two-way dog communication experience．
Researcher David Roberts says："Dogs communicate primarily through body language，and one of our challenges was to develop sensors that tell us about their behavior by observing their posture remotely．"
Sensors on the harness monitor the dog's heart rate and body temperature and software builds up a vocabulary，letting the human know what the dog is feeling．
What would dogs say if they could talk to us？The human can even communicate back through the harness thanks to vibration motors，supposedly by tapping into the dog's senses so that it can understand what you're trying to say to it．
The dog harness is designed for dogs involved in search and rescue and other front-line work，but it's got us dreaming of a beautiful future，one where humans and dogs can co-exist as equals，with the dog able to fully express itself at all times．

16．It turns out that nodding off in class may not be a bad idea，as a new study has shown that going to sleep shortly after learning new materials is the best way to remember them．
According to US lead author Jessica Payne，a psychologist at the University of Notre Dame in Indiana，nodding off after learning something new is like"telling"the sleeping brain what to remember．Along with colleagues，she studied 207students who slept for at least six hours per night．Students were randomly assigned to study something declarative （陈述的） at 9a．m．or 9p．m．，and returned for testing 30minutes，12hours or 24hours later．
Declarative memory refers to the ability to consciously remember facts and events，and can be divided into memory for events and memory for facts about the world．People use both types of memory every day-remembering where they parked today or learning how a colleague prefers to be called．
At the 12-hour retest，memory was better following a night of sleep compared to a day of wakefulness．At the 24-hour retest，with all students having received both a full night of sleep and a full day of wakefulness，students'memories were greater when sleep happened shortly after learning rather than following a full day of wakefulness．
"Our study confirms that sleeping directly after learning something new is beneficial for memory．What's special for this study is that we have shown sleep's influence on declarative memory，"Payne said．"Since we found that sleeping soon after learning benefited both types of memory，this means that it would be a good thing to go over any information you need to remember before going to bed．In some sense，you may be telling the sleeping brain what to consolidate．"

1．Imagine shopping in another country and spotting a beautiful scarf．The salesperson tells you the price，（32）but it's more than you want to buy．What do you do？
The answer depends largely on what part of the world you are in．Are you visiting Southeast Asia，the Middle East，Latin America or Africa？In these places，prices often are not set in stone．In fact，customers （33）are expected（expect） to bargain before agreeing to a price．
On the other hand，in North America，Europe and Australia，bargaining is rare and often not allowed．The price （34）listed（list） on a price tag cannot be changed．
Large stores and malls usually don't allow bargaining．On the other hand，outdoor stalls and flea markets，even in Western countries，usually allow bargaining．When in doubt，consult a guidebook---or （35）better（good） yet，a local friend．
（36）Although/Though/Whilebargaining custom vary，a few rules of etiquette apply in most cultures．First，avoid wasting people's time．If you don't intend to make a purchase，don't start bargaining．While bargaining，it is OK to walk away．But once you agree to a price，you （37）must buy the item．
Even in countries （38）that/which don't allow bargaining，you may find plentiful opportunities to save money．Many stores sell old items on clearance．Others offer discount cards to regular customers．Some of these can function as credit cards （39）within/in the store，and a few can even be used elsewhere．
