Rainforests, it turns out, are not created equal. Take the Amazon rainforest, an area that covers about 7 million square kilometers. But within that huge expanse are all kinds of ecological zones, and some of these zones, says Greg, Asner, are a lot more crowded than others. “Some forests have many species of trees,” he said, “others have few. Many forests are unique from others in terms of their overall species position” And all of these different small areas of forest exist within the giant space that is the Amazon Rainforest,.
So Asner, using the signature technique called airborne laser guided imaging spectroscopy, began to map these different zones from the air. “By mapping the trains of tropical forests from above,” he explains, “we are, for the first time, able to understand how forest position varies geographically.”
The results show up in multicolored maps, with each color representing different kinds of species, different kinds of trees, the different kinds of chemicals they are producing and using, and even the amount of biodiversity, the animal and plant species that live within each zone.
Armed with this information, Asner says decision-makers now have “a first-time way to decide whether any given forest geography is protected well enough or not. If not, then new protections can be put in place to save a given forest from destruction.”
Asner says the information is a great way for decision-makers to develop a “cost-benefit
ratio type analysis.” Conservation efforts can be expensive, so armed with this information, government leaders can ensure they are making the most of their conservation dollars by focusing on areas that are the most biologically diverse or unique.
The next step, Asner says, is to take his project global, and to put his eyes even higher in the sky, on orbital satellites. “The technique we developed and applied to map Peru is ready to go global,” Asner said. “We want to put the required instrumentation on an Earth-orbiting satellite, to map the planet every month, which will give the best possible view of how the world’s biodiversity is changing, and where to put much needed protections.” 25.

In the early 1980s, one of our neighbors asked my mom if she would make a few gift baskets for her to give as gifts for the holidays. My mom agreed and news of the unique gift baskets my mom was making spread like wildfire through the neighborhood. My mom was busy throughout the holiday season, so she asked a friend to help her. When the orders continued after the holiday
season for baby gifts, birthday gifts and more, it occurred to them that maybe this job could be turned into a business and they did it.
My mom went into her business because she had creative ideas. She got orders and filled orders. But there was no goal and no real plan. In 1991, my mom’s partner got into financial trouble and there was not enough money to support either mom or her partner.
So if you are led by your creativity or enthusiasm, make sure you ask yourself what your purpose to o your business is. If you don’t set goals, how will you know which direction to go in? Do you want to create jobs and growth in the economy? Are you looking for a hobby? You can’t keep score if you don’t know what game you are playing.
After my mom’s partner quit, she had to abandon her business to support herself. She swore she would run a business again and do it differently the next time. However, there wasn’t a “next time” for her. She passed away just after her 51st birthday. She never had someone tell her how important having a goal was, she never had a chance to be everything she could be. There are no right or wrong goals, only the ones that matter to you. set them so that you can make progress and achieve success, whatever they may mean to you. 29. What did the writer’s mom do after failing in her business? A. She found a different partner B. She celebrated her 51st birthday
C. She planned to have a second try with different methods D. She decided never to run a business again 30. What can we infer from the passage?
A. The writer began her business with a set goal B. The writer’s mother was a woman without creativity
C. The writer’s mother died because of her failure in business D. The writer’s believes having goals in mind ensures one’s success 31. How does the writer present his point of view mainly? A. By providing examples B. By explaining causes C. By making parisons D. By listing figures

Artificial intelligence keeps defeating human, it is making countless victories against human in different fields of life and trying to push human to the corner.
Google’s DeepMind has defeated the world’s number one player Ke Jie. Human brain somehow has been replaced by a machine and scientists are working very hard on developing a human brain by implanting a chip and connecting it to the tick neuron that connects the two hemispheres of the brain. Well, who doesn’t want to get his brain upgraded to be as smart as the brain of Albert Einstein or Charles Darwin?
Humans will probably one day invent a brain that can be implanted in the human skull and reprogram all the human thoughts, but this invention doesn’t seem to be happening in the foreseeable future since human brain took millions of years to evolve. Some scientists believe that human will defeat death in the next twenty hundred years but they can’t really predict how long it’s going to take to develop a human brain that can pletely replace the natural brain.
Despite of this acplishment in the field of artificial intelligence, it couldn’t crease people from believing that science can’t stand alone. For instance, AI can imitate human brain and most of the time outperforms it, but there are still a lot of hidden secrets. AI outsmarted Ke Jie but Ke Jie has consciousness unlike the AI, Ke Jie felt sad when he was defeated and buried his face in his hands but the AI didn’t feel happy and celebrate his victory.
The puter of 1960 is the same as the puter 2018 in terms of consciousness, there is no sings so far telling us that there is an algorithm(运算)that can make a conscious puter and decipher(译解)its feelings. We can predict what the future will look like according to the past, especially from scientific point of view but the development of human brain seems unpredictable and unknown. 32. What is the possible meaning of the underlined word “neuron” in Para. 2? A. the tube through which blood flows in your brain B. the kind of cell that carries information
C. the soft fatty substance in the hollow center of bones D. the bony part of one’s head which encloses his/her brain 33. What is Paragraph 3 mainly about?
A. It took millions of years for human brain to evolve
B. Humans wish to get their brains upgraded to be as smart as possible
C. Humans will probably invent a brain that can reprogram all the human thoughts. D. It is hard to develop a human brain that can pletely replace the natural brain 34. “Ke Jie felt sad when he was defeated” is mentioned in Para. 4 to__________. A. show that the AI has no human emotions
B. explain that AphaGo is virtually unbeatable in the board game C. tell us the acplishment in the field of artificial intelligence
