What does it take to be successful?
Many books have been written about the secrets of success. 1. Four key qualities stand out.
1. Vision.
Successful people visualize what they want. They have a picture in their mind of what their business will be like when they achieve their goals. This allows them to make decisions that support their vision. Most people couldn’t see what Bill Gates saw:that computers could have a value for personal uses. 2.
2. Determination.
Successful people are determined. You won’t find one successful person who hasn’t experienced any setbacks. Michael Jordan says,” I have missed more than 9,000 shots in my career. 3.…I have failed over and over and over again in my life. And that is why I succeed.”
3. 4.
Where other people see problems and limitations, successful people see possibilities and opportunities. When the web took off in the mid-1990s, computer programmer Pierre Omidyar saw the potential of the internet to connect people around the world instantly. So he created eBay, a hugely successful online market where individuals compete with big companies.
4. Enthusiasm.
5. Jecan-paul Gaultier had no formal training in design, but loved creating clothing and at a young age began sending his drawings to famous French designers. One of these designers recognized his talent and hired him as an assistant. Later, he set up his own line of clothing. And it quickly became a global success.
A. Creativity,
B. Responsibility.
C. I have lost almost 300 games.
D. Successful people love what they do.
E. However, who on earth have those secrets?
F. Today, most of us can't imagine life without a computer.
G. But what special qualities do successful people have in common?
In a university library, a student is writing an essay on his laptop. But that’s not all. He’s also reading instant messages online, listening to his music with headphones, and checking text messages on his cell phone. In today’s world, people use a wide variety of electronic media to multitask, doing several things at the same time. Neuroscientists are studying the brain to see what happens during multitasking and to see if multitasking affects the quality of what we do.
In a multitasking study conducted by French scientists Eienne Koechlin and Sylvain Charron, people were given one task requiring concentration. Brain images showed that both the left and right prefrontal cortex (前额叶皮质) were active as people worked. However, when the person is given a second task to do at the same time, the left prefrontal cortex look on task, and the right look the other. When doing two tasks, MRI (磁共振成像) images showed that the brain was rapidly switching between the first and the second task. The brain was not working on both tasks at the same time. It is concentrating on one task and then switching to the other.
In order to switch attention from one task to another, the brain must use its working memory. This is the brain’s ability to temporarily hold information while it does something else. When you multitask, the first task is stored in your working memory. Then your brain goes to the second task but when it returns to the first task, it must restart it, using working memory.
Although we think we are getting more done by multitasking, evidence shows that we do not. Researchers have found that people take longer to complete tasks and make more mistakes. When the French researchers expanded their experiment to include three tasks, surprisingly, the brain seemed to completely drop on task and only focus on two tasks. The French team concluded that the brain could not focus on more than two tasks at a time. Therefore, for a task that requires your concentration, it’s better to just focus on that one task until you are done.

D.To-present the applications of high-tech media.
2.What does the underlined “it”in paragraph 3 refer to?

C.The first task. D.The second task .
3.What can we learn about multitasking?
A.Electronic media improve its quality.
B.Three tasks can be well managed at a time.
C.It can damage the brain’s working memory.
D.It may result in the loss of speed and accuracy.
4.What can be the best title for the passage?
A.How does the brain multitask?
B.Why do we need to multitask?
C.Multitasking: a hew discovery of neuroscience
D.Multitasking: a way to expand the brain' s function
Pangolins (穿山甲) are the most trafficked (非法交易) mammals in the world and are facing extinction. To draw attention to these scaly (有鳞片的), anteater-like animals, a new wildlife documentary, Eye of the Pangolin, is attempting a unique way to inspire action and conservation. Partnering with the non-profit organization Pangolin. Africa, the documentary was made available on YouTube in May 2019. The intention is to reach communities wherever the Internet is available, especially African communities, who live near the animal’s habitats.
Over two years, the documentary crew traveled to South Africa, Ghana, Central African Republic and Gabon in search of the four unique species of pangolin, which has never been achieved before. Filmmakers Bruce Young and Johan Vermeulen say that they went into the shoot knowing relatively little about pangolins, but grew to respect and appreciate the animals. Getting close to the creatures over two years was a crash course in these secretive creatures. Johan Vermeulen said, "One thing however that might seem unimportant is that they are actually quite fussy eaters. You would think they would eat any type of ant, but they all prefer a specific type ant."
Pangolins are hunted illegally across Africa for their scales, which are used for traditional medicine, and their meat. In April 2019, Singaporean customs officials conducted two separate seizures of 24 tons of pangolin scales, which equals to the death of 69,000 pangolins.
Though the documentary focuses less on the trafficking of pangolins, and more on the animals in their natural habitat, the aim of the documentary is to inspire viewers around the world to call for action to end trafficking and protecting these unique creatures.
Filmed on location in South Africa, Ghana, Central African Republic, and Gabon, this powerful documentary is the story of two men on a mission to get all four species of African pangolin on camera for the very first time.

A.To study the situation of pangolins.

3.What’s the documentary mainly about?
A.The illegal trade of pangolins.
B.The medical function of pangolin's scales.
C.The life of pangolins in their natural habitats.
D.The efforts of Pangolin, Africa to save pangolins.
4.Where is the text most likely from?

My dad works with green technology. Last summer, he was sent to a small town called Gaviotas in Colombia. He decided to take me with him. At first I wasn’t too keen. What was I going to do in the middle of nowhere, in a country where I couldn’t even speak the language? And anyway, what was so special about Gaviotas?
My dad told me that Gaviotas was an example of how people could live without destroying the environment. This got me a bit more interested, so I did some research. I found out that Gaviotas was founded in 1971 by a group of scientists and artists. They had decided to build a completely new town in the remote, war-worn eastern Colombia where there was nothing.
When we eventually arrived, I was amazed by how green it was and my dad explained that they had replanted millions of trees. There were many different species of birds flying about and flowers everywhere. I was beginning to like it. My dad’s contact in Gaviotas has a son exactly my age Ricardo. He speaks really good English and so for the next week he was my guide to this amazing place. The first thing he pointed out to me was all the fantastic technology that had been invented there. Ricardo told me that they produce 70% of all their own energy and food with very little waste. The trees they planted more than compensate for any greenhouse gases they emit（排放）.
But Gaviotas is not a success just because of its green technology, it’s also a model for how people can live more peacefully together. Every family gets a free home, free meals and free schooling for the children. So there is no poverty. People get on well with each other. It’ s fantastic.
I was really sad to leave Gaviotas, but now I have a new dream: I hope that 20 years from now, we’ll all be living in towns like Gaviotas.

C.Modern but polluted. D.Small but advanced.
3.Where can you find the evidence to show that Gaviotas is a green town?
A.Paragraph 2. B.Paragraph 3.
C.Paragraph 4. D.Paragraph 5.
4.What does paragraph 4 focus on?
A.How scientists and artists founded Gaviotas.
B.How people in Gaviotas avoid waste.
C.Gaviotas is famous for its green technology.
D.Gaviotas is an ideal model of community.
