Scientists discovered 163 new species in Southeast Asia’s Greater Mekong region last year，but all are at risk of extinction due to climate change，the WWF said in a report released Friday.
The newly discovered creatures include a birdeating frog with fangs (毒牙)，a bird that would rather walk than fly and a gecko (壁虎) whose alien appearance inspired the report’s title of “Close Encounters”，the conservation group said.
The report was released ahead of major UN talks on climate change in Bangkok next week，which are being held before a makeorbreak summit in Copenhagen this December.
“Some species will be able to adapt to climate change，and many will not，potentially resulting in massive extinction，” Stuart Chapman，director of the WWF Greater Mekong program，said in the report.“Rare and endangered species like those newly discovered are especially vulnerable (易受伤害的) because climate change will further shrink their already restricted habitats，” he said.
“The new discoveries in 2010 include 100 plants,28 fish,18 reptiles,14 amphibians,2 mammals and a bird，”the WWF report said.The area spans Cambodia，Laos，Myanmar，Thailand，Vietnam and China’s Yunnan Province.
“Among the new species is the birdeating fanged frog，which remains hidden in a protected area of Thailand despite the fact that scientists are studying there for 40 years，” the report said.
The tigerstriped pit viper was discovered accidentally on an island off the coast of Vietnam when a scientist was looking for a lizard and his son pointed out that his hand was on a rock right next to the snake’s fangs.“We caught the snake and the gecko and they both proved to be new species，” researcher Lee Grismer of La Sierra University in California was quoted as saying in the report.The leopard gecko，found on another Vietnamese island，has the coloring of a leopard and bizarre orange，catlike eyes and thin legs.
The Greater Mekong region has proved a rich area for scientists.The WWF said in December 2010 that it had found 1,068 new species there between 1997 and 2009.

People use their mouths for many things.They eat，talk，shout and sing.They smile and they kiss.In the English language，there are many expressions using the word “mouth”．
For example，if you say bad things about a person，the person might protest(抗议) and say “Do not bad mouth me.” Sometimes，people say something to a friend or family member that they later regret because it hurts that person.Or they tell the person something they were not supposed to tell.The speaker might say，“I really put my foot in my mouth this time.” If this should happen，the speaker might feel down in the mouth.In other words，he might feel sad for saying the wrong thing.
Another situation is when someone falsely claims another person said something.The other person might protest，“I did not say that.Do not put words in my mouth.”
Some people have lots of money because they were born into a very rich family.There is an expression for this，too.You might say such a person，“was born with a silver spoon in his mouth.” This rich person is the opposite of a person who lives from hand to mouth.This person is very poor and only has enough money for the most important things in life，like food.
Parents might sometimes keep a child off sweet food as a form of punishment for saying bad things.For example，if a child says things she should not say to her parents，she might be described as a mouthy child.The parents might even tell the child to stop mouthing off.
But enough of all this talk.I have been running my mouth long enough.

How far would you be willing to go to satisfy your need to know？Far enough to find out your possibility of dying from a terrible disease？These days that’s more than an academic question，as Tracy Smith reports in our Cover Story.
There are now more than a thousand genetic(基因的) tests，for everything from baldness to breast cancer，and the list is growing.Question is，do you really want to know what might eventually kill you？For instance，Nobel Prizewinning scientist James Watson，one of the first people to map their entire genetic makeup，is said to have asked not to be told if he were at a higher risk for Alzheimer’s(老年痴呆症)．
“If I tell you that you have an increased risk of getting a terrible disease，that could weigh on your mind and make you anxious，through which you see the rest of your life as you wait for that disease to hit you.It could really mess you up.” said Dr.Robert Green，a Harvard geneticist.
“Every ache and pain，” Smith suggested，could be understood as “the beginning of the end.”“That’s right.If you ever worried you were at risk for Alzheimer’s disease，then every time you can’t find your car in the parking lot，you think the disease has started.”
Dr.Green has been thinking about this issue for years.He led a study of people who wanted to know if they were at a higher genetic risk for Alzheimer’s.It was thought that people who got bad news would，for lack of a better medical term，freak_out.But Green and his team found that there was “no significant difference” between how people handled good news and possibly the worst news of their lives.In fact，most people think they can handle it.People who ask for the information usually can handle the information，good or bad，said Green.
