A
Do you want to see majestic lions roaring, rare rhinos running and colourful birds flying You'll find this incredible display of nature in the Kenya Lake System in the Great Rift Valley.
First stop
Fly into Nairobi, the capital of Kenya.This great city is known for its fashion markets and beautiful art.And be sure to pick up some rich Kenyan coffee while you're there! Then head for the countryside.
Plan your trip
The largest of the three lakes in the system, Lake Nakuru, is less than 175 kilometers from Nairobi.But Lakes Bogoria and Elementaita are equally worth a visit.You can stay at one of several choices of luxurious cabins in the valley.And if you sign up for a trip, be sure to put flamingos (火烈鸟), the white and pink birds, at the top of your list.
Paradise
The Kenya Lake System is shallow and alkaline (碱性的)．That means it supports vegetation such as green algae, a food source for many waterfowl.Hundreds of species of birds flourish here, using this area as a major breeding and nesting ground.Water buffalo, leopards, monkeys and the endangered Rothschild giraffe also make this area their home.
Other sights
Wildlife isn't the only natural wonder in the Great Rift Valley.The valley marks a place where the earth is divided far below the surface.This rock separation below ground leads to noticeable features above ground.Walking around Lake Bogoria especially, you will see steam rising from hot springs.
Other activities include golfing, horseback riding and hiking.The fun doesn't stop when the sun goes down, either.The river valley is far from city lights, so many visitors gaze at the stars shining above.
If you are ready for a wildlife experience, don't hesitate!

Jadav Payeng lives on Majuli in Assam, India — the world's largest river island.In 1979, flooding took away a large part of forest along the Brahmaputra River.Wildlife was left without enough shade, and Payeng watched helpless animals begin to die off from the heat.
Deeply saddened，then the 16－year－old decided he would plant a young tree in the barren (贫瘠的) land every day for the foreseeable future and now his woodland covers 1,360 acres and it is home to Bengal tigers, rhinos, vultures and 115 elephants.
Amazingly, the work didn't come to light until the autumn of 2007, when he was accidentally discovered seeding (播种) his forest by wildlife lover Jitu Kalita.
Kalita had borrowed a boat to take pictures of birds around the Brahmaputra River, which runs around Majuli Island, and while travelling through the waters he saw something unusual.Kalita recalls, “I saw something strange ... It looked like a forest far in the distance.I began walking towards it.When I reached it, I couldn't believe my eyes.I had found a forest in the middle of a barren wasteland.” He was amazed by Payeng's story and spent time learning about his lifetime's work.
Payeng, who makes money with his wife selling cows' milk to local villages, still works hard taking care of his forest and says he will continue to plant young trees and seeds until the last moment of his life.He said at first that planting was very time－consuming (耗时的) but now it's much easier because the trees seed themselves.
Payeng's work has been recognised far and wide and in 2015 he received one of India's highest civilian awards, the Padma Shri.
Payeng says his dream is to fill up Majuli Island with forest again.Standing next to the first tree that he planted, he said, “People from around the world come here now because this forest amazes them.”

AI has been applied widely in a national park in northwestern China to track snow leopards (雪豹)．
The AI－aided digital toolbox can tell snow leopards in Gansu Province's Qilian Mountains National Park from other wildlife, using images captured by infrared (红外线的) cameras.
Located around 3,500 meters above sea level, the Qilian Mountains, with a large area of bare rocks sticking out from the grass, provide a favorable habitat for snow leopards.Though more than 200 cameras have been fixed in the area, sorting out relevant (有关的) information has not been easy for researchers.“To conduct further studies on the population, distribution and activities of the snow leopards, the cameras capture hundreds of thousands of videos and photos every quarter，” said Ma Duifang, who works for the Administration Bureau of Qilian Mountains National Park.“Even a slight movement in the environment, such as a pleasant wind blowing over the grass, can trigger (启动) the cameras.Sometimes, curious wildlife knock into the device, triggering the cameras, which take pictures of mere clouds.” Ma and his workmates had to go through each video, and information about the animals that appeared in the images also required human efforts.So it often took them several weeks to complete these tasks.
Thanks to AI technology, researchers in the Qilian Mountains National Park no longer need to rack their brains in search of snow leopards hiding in the wild.“The forest keepers can now locate a snow leopard from 1,000 pictures in only about 20 minutes, much faster than before，” said Huang Xiangqi, one of the technology's developers.“We hope we can combine monitoring data with field investigations to help researchers identify the snow leopards so as to draw up a more specific plan for their protection.”
8．Why is it hard for researchers to sort out relevant information
A．The mountain is high.
B．Snow leopards run too fast.
C．They are badly in short of workmates.
D．There are many irrelevant videos and photos.
9．How does the AI－aided digital toolbox help the researchers
A．By searching for snow leopards in the forest.
B．By making data processing quicker and easier.
C．By controlling the movements of snow leopards.
D．By recording snow leopards' changing populations.
10．Which of the following is a suitable title for the text
A．Snow Leopard — a Most Important Animal in Gansu
B．Ma Duifang — a Leading Expert in Snow Leopard Study
C．Infrared Camera — a Creative Invention for Wildlife Protection
D．AI－aided Technology — an Effective Helper in Snow Leopard Protection
11．What is the text likely to be
A．A news report.　　　　　　 B．A scientific paper.
C．An official document. D．A product introduction.
D
Aviation (航空业) is a major contributor to climate change, and also one of the hardest places to give up using fossil fuels (化石燃料)．New research suggests we could reduce the carbon footprint of jet fuel by 165 percent by making it out of food leftovers.
Scientists have shown that making jet fuel from food waste could greatly reduce emissions (排放)．In a recent paper，they show that their fuel meets aviation standards (标准), and they've partnered with Southwest Airlines to speed up and start flight trials.
Wet wastes like food leftovers are energy－rich，and previous research has shown that they could be turned into volatile fatty acids (VFAs) and then be made into jet fuel.But doing so in a way that would meet strict aviation standards was an unsolved problem.
The new way designed by the researchers adds extra carbon to VFAs, turning them into paraffin (石蜡) that is exactly the same as that found in standard jet fuel.A mixture of 10 percent bio－paraffin and 90 percent traditional jet fuel met aviation standards, and the team says it's likely to get official recognition soon.
It was shown that the new bio－paraffin had the potential to reduce greenhouse gas emissions by 165 percent compared to standard jet fuel，which is far higher than the 50 to 70 percent reductions achieved by previous bio－jet fuels.Most of the emissions reduction came from taking wet waste away from landfills (垃圾填埋场) where it breaks down into a powerful greenhouse gas.
There are limits on how much of an impact the new fuel could have，though.The total energy content of all the wet wastes in the US still only accounts for about 20 percent of the amount of jet fuel.However，finding a way to make society's leftovers into something as valuable as jet fuel while significantly slashing its environmental impact is a major breakthrough.The partnerships with major airlines suggest yesterday's dinner may soon be flying you across the country.
12．What can be inferred from the first three paragraphs
A．Aviation is the hardest place to give up using fossil fuels.
B．Making jet fuel out of food leftovers will worsen pollution.
C．Energy－rich food leftovers can be turned into jet fuel directly.
D．Scientists didn't know the way that would meet strict aviation standards.
13．Why can the new bio－paraffin reduce greenhouse gas emissions greatly
A．It is made by adding extra carbon to VFAs.
B．Paraffin found in standard jet fuel is exactly the same as it.
C．Wet waste is taken away from landfills where it changes into a greenhouse gas.
D．It has met aviation standards and has been officially recognized.
14．What does the underlined word “slashing” in the last paragraph mean
A．Stopping. B．Reducing.
C．Destroying. D．Balancing.
15．What is the author's attitude to making jet fuel out of food waste
A．Supportive. B．Negative.
C．Doubtful. D．Unclear.

Endangered species
An endangered species is a group of animals or plants that could soon become extinct. __16__ Many species are nearly extinct and could disappear off the face of the earth very soon if we don't do anything to save them.There are many reasons why species become endangered.
Habitat destruction is the main reason why animals become endangered and this happens in two ways.When humans move into a new area, the animals' habitat is destroyed and there is nowhere for them to live and nothing for them to eat because humans chop down trees and build houses and farms. __17__ Chemicals in rivers and poisons on farms cause the destruction of animals' homes and food supplies.
__18__ Animals have been brought to the edge of extinction because they are killed for their highly valued meat, fur, bones or skin, or just for sport.Overfishing has resulted in many large sea creatures like whales and sharks becoming endangered species.
__19__ We should take care not to pollute natural areas, and farmers or companies who destroy animal habitats should face severe financial penalties (处罚)．The public can help out by refusing to buy any product made from these animals' body parts.Governments can help, too, by making it against the law to hunt, fish or trade in endangered species.They can also provide funding for animal sanctuaries (保护区), to protect animals from extinction by breeding more endangered animals, which they later release into the wild. __20__
A．Animal habitats are also destroyed because of pollution.
B．Endangered species are also the result of hunting and fishing.
C．Recent changes, however, have helped to improve the situation.
D．Eventually, all the creatures on the earth will enjoy being together.
E．So what can individuals and governments do to protect endangered species
F．Extinction happens when the last of the species has died out and there will be no more.
G．If we all cooperate and take these steps, we will protect these animals for future generations.

When I was eleven years old, I moved to Tampa, Florida.My parents traveled for a living, so Aunt Emily took care of me while they were away.One rainy morning, there was an old lady who was dressed in a bright orange coat carrying a rubbish bag and a stick.“What's that old lady doing？” I asked Emily, pointing out the window to the street in front of the house.
Hearing my question, Emily answered, “She's picking up rubbish around here for fun.” “Oh，” I answered. “Interesting ...Why would someone think picking up rubbish was fun？” For a long time, I often saw that old lady — rain or shine — on my way to school.In the beginning, I thought she was crazy to pick up rubbish.However, I finally smiled and waved at her each time I saw her.
Later, when I moved to college, I saw rubbish in the grass and felt really angry about it.I'd think，“Why isn't anyone picking up rubbish People are so unconcerned！” But shortly after that, I said to myself, “Why do I think picking up rubbish is someone else's duty？” And I couldn't walk past trash without feeling guilty (内疚的)．
So while walking in the college, I began picking up rubbish and made sure the campus was in better shape than I previously found it.My behavior influenced some students.They started to help out.
Like me, they also picked up rubbish whenever they noticed it.And our college became more beautiful.Seeing it, I began to think, “If I could pick up rubbish outside the college — in other places of the town, it may make a big difference to the town.”
But picking up rubbish in front of many people outside the college needs courage.It could be embarrassing.But it was the right thing to do.I decided to try it.

参考范文：
One morning, I went out to pick up rubbish.Some people watched me with a strange look that seemed to say I was crazy.And suddenly, I remembered that the old lady who often picked up rubbish years ago.The interesting thing was that I was acting just like her! As strange as it might sound, picking up rubbish is kind of fun for me! Gradually, many people realized I was volunteering to help make our town clean.They praised me and thanked me.
Then I decided to encourage more students to do this in the town.Surprisingly, they agreed and we set up a volunteer organization.We bought each student a bright orange coat with words on it: Let's make our town cleaner! And we spent time not only picking up rubbish but also sorting through it and recycling it.Something amazing happened — the strangers around us helped out too! I thought to myself, “The old lady made all this happen; she made a big difference to my life.”
