Dear editor．

13．You think you know your dog．（36）C She probably recognizes you when she sees you．But can a dog tell by simply looking at you whether you have a happy or an angry expression on your face？Researchers in Austria have taught pet dogs to know the difference．
（37）A When dog owners shout or speak in a strong，sharp voice，dogs often act guilty and quietly move away from the area．
Recently，researchers found that dogs can look at our faces，and tell the difference between a smile and a frown．The animals were able to recognize a look of approval from one of disapproval．Researchers at the University of Veterinary Medicine performed a series of experiments．（38）FThey showed the dogs two pictures of either the upper or lower half of a person's face．On one picture the person looked happy．The other appeared angry．The dogs were then shown images of the eyes or mouths of people they had never seen before．
（39）D Once the dogs learned to recognize which image was happy or angry，they could easily identify the same expressions in pictures of any face．Future studies will try to show whether dogs can learn the meaning of facial expressions．（40）G
The researchers'findings were published in the journal Current Biology．They provide the first solid evidence that humans are not the only species that can read the body language of another species．

A．Dogs are very aware of sound．
B．Dogs have feelings just as you do．
C．But how well does your dog know you．
D．They were also shown the left half of the faces used in training．
E．Some dogs are very unhappy when they are left alone for a long time．
F．They taught dogs to recognize facial expressions．
G．For example，whether a frown shows that someone is angry．

3．While staying in a five-star hotel，you will feel completely atease（舒适）

10．On Jan 15th，2015，Justin Valdez，a college student，was shot in a subway station in San Francisco．The surveillance video（监控录像） showed that before Justin was killed，the killer pulled out his gun several times，and even wiped his nose with it．However，nobody noticed the killer．The surrounding passengers all focused on their cell phones．
We may see the same scene everywhere in our life：in subway stations，restaurants，elevators and so on，people are watching their cell phones．From a family reunion to a date with a friend，people couldn't stop checking their twitter and facebook on the cell phones，ignoring the persons in front completely．Phubbing（低头症） not only involves young people，but also the elderly and kids．
"Phubbing"is a new term which comes from the words"phone''and"snub（冷落）"．It describes the habit of snubbing someone in favor of a cell phone．The word"phubbing"was included in the Australian National Dictionary in 2012．Obviously，the indifference（冷漠） and rudeness of the information age are spreading globally．A Stop Phubbing campaign website has been set up．You can find the slogan of the website as follows："stop twittering，stop posting photos…enjoy your food，enjoy the music and respect others．"
Phubbing appears harmless．However，it does influence our life．Jimmy，an epicure（美食家），wrote in his blog："I can no longer focus on what I am eating since I started twittering．My skill of food photography has improved very fast，while my interest in food drops as a result．"
Let us put down our cell phones and re-enjoy the real taste of our food and the warmth of interpersonal communication．
33．The case of Justin Valdez is given in the first paragraph to showB
A．gun violence happens easily in the US
B．phubbing may lead to terrible disasters
C．the killer didn't mean to kill him
D．the killer had made a careful plan
34．Jimmy's words suggest thatB
A．phubbing is actually harmless
B．phubbing stops people enjoying their life
C．phubbing affects people's eating habits the most
D．phubbing helps people improve their photographic skills
35．What is the text mainly about？D
A．How the word"phubbing"came into being．
B．The popular campaign of stop phubbing．
C．The meaning of the word"phubbing"．
D．The great harm of phubbing．

7．Human Flesh Search-thousands of individuals working to find and make public someone's personal information，mostly online-will be ruled as leaking personal data，which is against the law，according to China's top court．
Internet users or network service providers who leak people's personal information such as phone numbers，addresses，and clinical data will have to hold legal responsibility．
Network service providers will also be held responsible if they are aware that their users have violated others'rights but have failed to take action．
The decision comes after years of arguments over whether it's right for the public to try those who behave wrongly．
On the one hand，cyber hunting does have its positive influences．Some public officials have been removed from their positions after human flesh searches led to corruption investigations．During disasters like the Sichuan earthquake in 2008，the search method also helped many people to find their loved ones．
But many think that online cyber hunting is creating a threat to privacy．"People's‘unusually high enthusiasm'makes the human flesh search engine phenomenon unique，"Xujun Eberlein，a Chinese American author and commentator，told Forbes．"Participants often‘reach out their hands'thoughtlessly，violating people's rights instead of being righteous（正直）．"

8．"Plants were supposed to grow larger with increased carbon dioxide in the atmosphere，but changes in temperature，humidity and nutrient availability seem to have trumped the benefits of increased carbon dioxide，"said researchers from the National University of Singapore．
45percent of the species studied now reach smaller adult sizes than they did in the past．The researchers point out that warmer temperatures and changing habitats，caused by climate change，are possible reasons for the shrinking of creatures．
"We do not yet know the exact mechanisms involved，or why some organisms are getting smaller while others are unaffected，"the researchers said．"Until we understand more，we could be risking negative consequences that we can't yet quantify．"
The change was big in cold-blooded animals．Only two decades of warmer temperatures were enough to make reptiles （爬行动物） smaller．An increase of only 1℃caused nearly a 10percent increase in metabolism （新陈代谢）．Greater use of energy resulted in tiny tortoises and little lizards．Fish are smaller now too．Though overfishing has played a part in reducing numbers，experiments show that warmer temperatures also stop fish growth..There is a recent report on warmer temperatures'negative effects on plankton （浮游生物），the base of the marine ecosystem．
Warm-blooded animals weren't immune from the size change caused by climate change．Many birds are now smaller．Mammals have been miniaturized too．Soay sheep are thinner．Red deer are weaker．And polar bears are smaller，compared with historical records．This isn't the first time this has happened in Earth's history．
55million years ago，a warming event similar to the current climate change caused bees，spiders and ants to shrink by 50to 75percent over several thousand years．That event happened over a longer time than the current climate change．
The speed of modern climate change could mean organisms may not respond or adapt quickly enough，especially those with long generation times．So，it is likely that more negative influences of climate change will be shown in the future．
32．Which of the following would be the best title for the passage？B
A．Why do some species become smaller？
B．Species become smaller as climate warms．
C．Climate change has many negative effects．
D．How does climate change in Earth's history？
33．The underlined word"trumped"in the first paragraph can be replaced by"A"．
A．beaten
B．increased
C．strengthened
D．equaled
34．What can we learn from the passage？C
A．Cold-blooded animals become smaller because of the lack of food．
B．Birds have suffered more from climate change than fish．
C．Climate change has even affected plankton negatively．
D．The warming event has never happened in Earth's history before．
35．What is the author's attitude toward climate change？B
A．Optimistic．
B．Concerned．
C．Indifferent．
D．Confident．
