Squirrels often communicate with whistles, chirps and chucks, which sound like the word “chuck”. Whistles and chirps are like the sounds that many birds make. Now scientists have translated some of their squirrel-speak.
Hare, a professor of zoology at the University of Maniloha in Winnipeg, and his team managed to record squirrels' alarm calls. The researchers studied the sounds and then played them back to 60 wild squirrels, which the scientists approached individually with a video recorder to capture(抓拍）their responses. Some squirrels lifted their heads up and became alert(警惕的）. Creatures that were more frightened simply ran for their lives and dived into caves.
"In effect then, whistles that mix with chucks say 'there's an enemy of average threat that's here', and whistles without chucks say 'there's an enemy of seemingly average threat around here somewhere', while pure chirps say, 'I'm hiding here because there's an immediate danger. ' " Hare told. Discovery News.
Hare and some other researchers believe such sounds are part of an advanced language that develops just as all other communication systems.
Although squirrels risk their lives when they call out to warn others of threats, other squirrels might admire this behavior, thus increasing the caller’s social status, like humans who look up to heroes. Hare added that other animals, such as birds, probably understand at least some squirrel language, since they also may benefit from the alarm calls.
In fact, another Canadian study found that deep-voiced, black-capped chickadees have their own language too. According to certain research, there are a lot of tidings in chickadees' calls, such as directing fellows' activities, keeping in contact between mates, and raising alarms.
While chickadees and other birds are often welcomed into gardens by homeowners, squirrels are frequently viewed as pests(害兽）. Hare wishes a greater understanding of the complex social lives and communication systems of squirrels will provide “hope that humans will gain a greater appreciation and stop doing harm to these animals”.

We use both words and body language to express our thoughts and opinions and to communicate with other people. We can learn about what a person is thinking by watching his or her body language. Words are important, but the way a person stands, folds his or her arms, or moves his or her hands can also give us information about his or her feelings.
Just like spoken language, body language varies from culture to culture. Making eye contact —looking directly into someone’s eyes — is in some countries a way to show interest. In other countries, however, eye contact is rude or disrespectful. The gesture for Ok, making a circle with one’s thumb and index finger, has different meanings in different cultures. In Japan, someone who sees another person making the gesture will think it means money. In France, a person seeing the same gesture will think it means zero. In Brazil and Germany, however, the gesture is rude. The thumbs-up gesture, meaning “great” or “good job” in the US is rude in Nigeria, but in Germany and Japan it means the number one. The “crazy” gesture, moving the index finger in a circle in front of the ear, means “you have a phone call” in Brazil.
Even the gesture we use for “yes” and “no” are different around the world. In many countries, shaking one’s head means “no”, and nodding means “yes”. In Bulgaria, parts of Greece, and Iran, however, the gestures have the opposite meaning. There are also differences as to how often we touch each other, how close we stand to someone we are talking to, and how we act when we meet or part. In some countries, for example, France and Russia, a visiting friend is greeted with a kiss on the check, in other countries people greet each other with a firm handshake, a loving hug, a bow or a simply a nod of the head.
While there are many different interpretations of our body language, some gestures seem to be universal. Pressing one’s palms together and resting one’s head on the back of one’s hand while closing the eyes as if sleeping means “I am tired.” A good way of saying “I am full” is moving the hand in circles over the stomach after a meal. If a person pats his or her stomach before a meal, it usually means “ I’m hungry.”
Perhaps the best example of universally understood body language is the smile. A smile can help us get through difficult situation and find friends in a world of strangers. A smile can open doors and tear down walls. It can be used to express almost any emotion. We can use a smile to apologise, to greet someone, to ask for help or to start a conversation. We can smile at ourselves in the mirror to make ourselves feel happier and stronger. And if we are feeling down or lonely, there is nothing better than to see the smiling face of a good friend.
1.In our daily life, which of the following do we use to communicate with each other?
A．gestures B. words C. smiles D. all above
2.As a Chinese , if you are lost in Germany, without knowing German, you’d better---- to ask for help?
A.use eye-contact B. thumb-up
C. smile D. say “excuse me”
3.What does this passage mainly about?
A. all the gestures in the world
B. the same body language in the world
C. gestures in the western countries
D. using proper gesture to express yourself
4.The underlined word “universal” in the last second paragraph probably means ______.
A. wide B. common C. not similar D. in space

The £109 Nest Protect Smoke Alarm promises Internet alerts（警报）and an end to the low battery chirp（短而尖的叫声）. Besides, it uses a voice to tell you where the fire is.
The alarm is the first UK product from Nest, which is run by iPod-inventor Tony Fadell. The company claims the device’s batteries will last for up to seven years. The device will offer a spoken warning before it sounds a major alarm. Also it will use text messages and apps on your phones to alert users to low-level risks.
The present smoke alarms constantly alert users to non-existent threats, which will make many users annoyed and finally remove their batteries altogether. “We’ve all experienced the smoke alarm going off while we’re cooking. Sometimes, we need to search for the source of that non-stop low-battery chirp at midnight,” said Fadell. “Therefore, every time a smoke alarm cries wolf, we trust it a little less, and then — in a moment of frustration — we take the batteries out to stop the beep（嘟嘟声）. And that leaves us and our families at risk.”
If the Protect smoke alarms are used, they can be set up in up to ten zones, so that the clear warnings tell users where the risk has been detected.
“Safety shouldn’t be annoying,” said Matt Rogers, Nest founder and vice president of engineering. “It was unacceptable to us that one in eight houses in the UK has a non-functioning smoke alarm. These products are required by law and are supposed to keep us safe, yet people hate them. We wanted to change that.”
1.For what purpose did Nest create the Protect Smoke Alarm?
A. To predict low-level fire risks. B. To experiment with a new battery.
C. To improve present smoke alarms. D. To avoid the low-battery chirp.
2.What did Tony Fadell really want to tell us in Paragraph 3?
A. One of his cooking experiences.
B. Disadvantages of present smoke alarms.
C. His growing distrust of smoke alarms.
D. His source of annoyance to crying wolf.
3.Which of the following are the advantages of the Protect Smoke Alarm?
a. Rechargeable batteries b. A talking smoke alarm
c. Longer battery life d. Going off constantly
e. Internet connection
A. a, b, c B. c, d, e C. a, c, e D. b, c, e
4.What can we know from the last paragraph?
A. In the UK people seldom set up smoke alarms.
B. Matt Rogers didn’t like the safety requirements.
C. Non-functioning smoke alarms make people annoyed.
D. The government should pay attention to safety issues.

Would it surprise you to learn that, like animals, trees communicate with each other and pass on their wealth to the next generation?
UBC Professor Simard explains how trees are much more complex than most of us ever imagined .Although Charles Darwin thought that trees are competing for survival of the fittest, Simard shows just how wrong he was. In fact, the opposite is true: trees survive through their co-operation and support, passing around necessary nutrition “depending on who needs it”.
Nitrogen（氮） and carbon are shared through miles of underground fungi（真菌） networks, making sure that all trees in the forest ecological system give and receive just the right amount to keep them all healthy. This hidden system works in a very similar way to the networks of neurons（神经元）in our brains, and when one tree is destroyed, it affects all.
Simard talks about “mother trees”, usually the largest and oldest plants on which all other trees depend .She explains how dying trees pass on the wealth to the next generation, transporting important minerals to young trees so they may continue to grow .When humans cut down “mother trees” with no awareness of these highly complex “tree societies” or the networks on which they feed, we are reducing the chances of survival for the entire forest.
“We didn't take any notice of it.” Simard says sadly .“Dying trees move nutrition into the young trees before dying, but we never give them chance.” If we could put across the message to the forestry industry, we could make a huge difference towards our environmental protection efforts for the future.
1.What would be the best title for the passage?
A. Old Trees Communicate Like Humans
B. Young Trees Are In Need Of Protection
C. Trees Contribute To Our Society
D. Trees Are More Complex Than You Think
2.In Simard's opinion, trees _______
A. compete for survival
B. protect their own wealth
C. depend on each other
D. provide support for dying trees
3.We can learn from the passage that .
A. “mother trees” are usually of no use to other trees.
B. Charles Darwin had the same thought as Simard.
C. if “mother trees” are cut down, the survival for the entire forest will be affected.
D. people know much about the complex “tree societies”.
