Tracking wildlife is a tough job.Take the case of a one-eared leopard named Pavarotti. "He was a very big beautiful male,and he had a very,very deep,deep roar,and so they named him after Pavarotti."
One day,Kasim Rafiq,a wildlife biologist at Liverpool John Moores University got up at the crack of dawn,followed Pavarotti 's tracks and tried to find him.However,the tracks took he off road and the wheel of his car was stuck in the mud.He wasted several hours getting it out.And on the way back to camp,he bumped into some local tour guides and their guests,who'd had way better luck spotting Pavarotti that morning.Rafiq then realized that tourist wildlife sightings might be an untapped source of information about wild animals.
So he and his team worked with a travel agency in Botswana to analyze 25,000 tourist photographs of wildlife.They used those as sightings of lions,leopards,and wild dogs.They then compared those data to the estimates they made with traditional wildlife biology tactics:stuff like camera traps,track surveys,and "call-in stations" - where they play sounds of distressed animals in the middle of the night and see whopops by.
It turned out that the estimates from tourist photos were just as good as those from traditional methods.The idea is not to put wildlife researchers out of a job. "The reality is there's so many interesting things we still have to find out about these large animals and so many conservation projects that need to be carried out that we don't have the time or resources to do them all." And the researchers would have missed the cats without the citizen science data.

1.If you see a group of people dancing and singing on the street or in the railway station,you don't need to feel surprised.They are a flash mob(快閃族),which is a group of people who come together suddenly in a public place,do something unusual for a brief period of time,and then quickly break up.They are usually organized with the help of the Internet or other digital communication network.
At a predetermined time,they gather and perform some distractions(消遣)such as waving their hands and exchanging books.Then,they quickly break up before the police can arrive.Using mobile phones the flash mob can change its location if the first one has been replaced for any reason.
Bill Lasik,senior editor of Harper's Magazine,organized the first flash mob in Manhattan in May 2003 and the first successful flash mob came together on June 3,2003--after the first attempt was foiled at Macy's department store.Lasik claimed that the activity was designed to make fun of hipsters(時(shí)髦的人),and call attention to the cultural atmosphere.
Flash mob gatherings can sometimes shock people.Such an activity might seem amusing and untrue,but it also might frighten people who are not aware of what is taking place.Undoubtedly,flash mobs can serve as good political tools in any direction.They also have great economic potential,such as using flash mobs to advertise a product.
The flash mob is now becoming more and more popular.People use it to do many things.For example,in 2009,Michael Jackson's fans took part in a flash mob to remember him.Hundreds of his fans gathered singing and dancing Michael's famous song Beat It together.Flash mobs give people from all walks of life an opportunity to come together to create a memory.

2.The world is a greener place than it was 20 years ago.Recent NASA satellites data(2000-2017)have shown that human activities in China and India dominate this greening of the planet,thanks to ambitious tree-planting programmes in China and intensive agriculture in both countries.
The researchers from Boston University found that global green leaf area has increased by 5 percent in the new century,an area equal to all of the Amazon rainforest.China alone accounts for 25% of the global net increase in leaf area with only 6.6% of global vegetated area.China's contribution comes in large part from its programmes to conserve and expand forests,taking up about 42 percent of the greening.The greening from farmlands in China is about 32%,but that in India is about 82%.
Rama Nemani,a research scientist at NASA's Ames Research Centre and a co-author of the study said, "When the greening of the Earth was first observed,we thought it was due to a warmer,wetter climate and fertilization from the added carbon dioxide in the atmosphere.But with data from NASA satellites,scientists realized that humans are also contributing,which was all against our expectations."
Nemani sees a positive message in the new findings. "Once people realize there is a problem,they tend to fix it," he said. "In the 1970s and 1980s in India and China,the situation around vegetation loss was not good.In the 1990s,people realized it,and today things have improved.Humans are incredibly resilient.That is what we see in the satellite data."
However,the researchers rang bells as well.They said that the gain in global greenness did not necessarily make up for the loss of natural vegetation in regions like Brazil and Indonesia.
(1)What is the second paragraph mainly about?
A.The decreasing size of the Amazon rainforest.
B.China's bigger contribution to global greening.
C.Total global green leaf area in the new century.
D.China's programmes to conserve and expand forests.
(2)What surprised scientists regarding global greening?
A.Human activities.
B.Suitable for analyzing data.
C.A warmer and wetter climate.
D.Carbon dioxide in the atmosphere.
(3)What does the underlined word "resilient" probably mean?
A.Good at making programmes.
B.Suitable for analyzing data.
C.Able to make corrections.
D.Active in planting trees.
(4)What does the last paragraph imply?
A.It is urgent to protect global natural resources.
B.Much remains to be done for global greenness.
C.Brazil and Indonesia lose most of their vegetation.
D.Global greenness needs all countries to work together.發(fā)布:2024/12/20 5:0:3組卷:7引用:1難度:0.6
