Once there were many thousands of Gourma Desert （沙漠） elephants in Mali， a country in West Africa． Now． there are fewer than four hundred．
Why did the number of the elephants drop so quickly？ On the one hand， the elephants' main lake． their only water source （来源） dried up． On the other hand，the land which the elephants lived on was overused by humans．
To protect the elephants' living environment， the Mali Elephant Project （MEP） was started in 07． MEP met with local people and helped them make rules of using land and water． As a result， the situation became better and there was more food， forest and grassland．
However． from 2012 to 2016， poaching （偷猎） and illegaltrade in the elephants increased rapidly Eighty﹣three elephants were lost in 2015 alone， and another fifty﹣one elephants were killed in 2016．"If this situation goes on， all the Gourma elephants will be killed by 2020．" said a member of MEP．
Luckily． the voice of MEP was heard． More organizations （组织） have joined together to educate the local people that trading elephants is against the law．Elephant poaching has dropped to a very low level． The local people have learned to live peacefully with the elephants，one of the wildlife treasures in the world．

In Chicago, a computerized system has been developed that controls(管理)traffic on the city’s 235 miles of seven expressways. Now one—a controller—can follow the movement of Chicago’s traffic by looking at a set of lights. The system uses electric sensors(感应器) that are built into each expressway, every half a mile. Several times a second, the computer receives information from each sensor and translates it into green, yellow or red lights on a map in the control room. A green light means traffic is moving forty-five miles an hour, yellow means thirty to forty-five miles an hour, and red means heavy traffic—cars standing still or moving less than thirty miles an hour.
“See that red light near Austin Avenue?”the controller asked a visitor.“That’s a repair truck fixing the road, and the traffic has to go around it.”At the Roosevelt Road entrance to the expressway, the light kept changing from green to red and back to green again.“A lot of trucks get on the expressway there,”the controller explained.“They can’t speed up as fast as cars.”The sensors show immediately where an accident or a stopped car is blocking the tr
affic, and a truck is sent by radio to clear the road. The system has lowered the number of accidents by 18 percent. There are now 1.4 deaths on Chicago’s expressway for each one hundred million miles traveled, while in other parts of the county there are 2.6.
Traffic experts say that the Chicago system is the “coming thing”.Systems like Chicago’s are already in use on some expressways in Los Angeles and Houston.“Chicago has taken the lead,”said New York City’s traffic director and he added,“Chicago’s a good example.”

Dogs might have the latest tools in the fight against cancer （癌症）：their noses!Researchers at California's Pine Street Foundation （PSF） say they have trained five dogs to smell cancer on a prison's breath.This could be exciting news.
A dog's sense of smell may be 10，000 to 100，000 times stronger than ours.But can dogs really smell illness？PSF researcher Michael McCulloch says yes. "We were very surprised by how exact they were，" he said. "They were telling who had cancer，and they were also saying who didn't."
McCulloch and his team asked four healthy people and one with cancer to blow into plastic tubes （塑料管）.Special materials in the tubes kept the things of each breath.The tubes were then placed one yard apart.Finally the dogs were allowed to smell the tubes.Each dog had been trained for three weeks to sit when it smelled cancer.Ninety﹣nine percent of the time，the dog sat next to the tubes blown into by patients with lung cancer.The dogs were right 88 percent of the time about breast cancer.

Number of Times the Dogs Sat Down |
