“It?s so interesting and super easy,” she laughs. “My mum taught me in a nice way.” She adds: “I want to finish the course in two years. Then I?m going to do my PhD in financial maths when I?m 13. I want to have my own bank by the time I?m 15 because I like numbers and I like people and banking is a great way to help people.”
And in case people think her parents have pushed her into starting university early, Esther disagrees. “I actually wanted to start when I was seven. But my mum didn?t agree.” After three years of begging, Mother Efe finally agreed to explore the idea.
Esther has always jumped ahead of her peers. Her mother noticed her daughter?s gift for figures shortly after she began homeschooling her at the age of three. Initially, Esther?s parents had enrolled her in a private school but after a few short weeks, the usually-energetic youngster refused to go back to that school because the teachers didn?t let her talk in class. In the UK, education is not compulsory until five, so Efe started to do little things at home by teaching basic number skills but Esther was miles ahead. By four, her natural talent for maths had seen the eager student move on to algebra (代数学) and quadratic equations (二次方程式).
And Esther isn?t the only maths miracle in the family. Her younger brother Isaiah, 6, will soon be sitting his first A-level exam in June.
56. Which of the following makes Esther Okade different from her normal peers? A. She is the youngest college student in the UK. B. She goes to university at a much earlier age. C. She often gets full marks in maths exams. D. She loves acting as a university student. 57. From the passage we can learn that _____.
A. Esther thinks her parents expect too much of her B. Esther cannot adapt herself well to college life C. Estherasked to go to university even earlier D. Esther dislikes being taught at home
58. What might be a main factor that has ledto Esther?s being a maths genius? A. The gene from her family. B. Her course in the university. C. The criticism from her teachers. D. Her mother?s homeschooling. 59. Esther can be described as a girl who _____. A. is ambitious and has a clear goal B. is creative and loves exploring the unknown C. is rebellious but ready to help others D. is energetic but reluctant to challenge herself

Unless you are like Nasty Gal?s founder Sophia Amoruso, the passwords you use to access your email and the endless other accounts you need for work aren?t filled with intention. With increasing security requirements, it?s likely your word/number combinations are becoming even less memorable. But new research suggests it may not be long before you won?t need to memorize passwords.
“Brainprint”, published in Neurocomputing, reveals that the brain?s reaction to certain words could be a

unique identifying code—like a fingerprint—that could eventually replace passwords.
In a small experiment, the researchers measured the brains? signals of 45 volunteers as they read through a list of 75 acronyms such as FBI and DVD. The word-recognition response differed so much between each participant that a second experiment using a computer program could identify each one with 94% accuracy.
It?s not enough to feel totally secure, but promising enough to hint at the future of securing sensitive information.
The advantage of using such a biometricsystem (生物识别系统) is that it can be used for continuous verification(验证), New Scientist points out.Passwords or fingerprints only provide a tool for one-off identification. Continuous verificationcould in theory allow someone to interact with many computer systems at the same time or even with a variety of intelligent objects, without having to repeatedly enter passwords for each device.
As Hollywood has illustrated, it?s simply a matter of cutting off a finger to steal that person?s identity. “Brainprints, on the other hand, are potentially cancellable,” said Sarah Laszlo, assistant professor of psychology and linguistics at Binghamton University and co-author of the study, “So, in the unlikely event that attackers were actually able to steal a brainprint from an authorized user, the authorized user could then ?reset? their brainprint.”
Until now, brain signals have been a challenge to understand. This experiment leaped over the obstacle by focusing on the brainwaves from the specific area that reads and recognizes words. The signal is therefore clearer and easier to measure.
The problem, so far, is that the brain signal is still not as accurate as scanning someone?s fingerprint, and initially requires sticking diodes (二极管) on your head in order to get a read. That?s ok, according to Zhanpeng Jin, assistant professor at Binghamton University and coauthor of the study, because brainprint isn?t going to be mass-produced any time soon. He says the researchers foresee its use at places such as the Pentagon, where the number of authorized users is small, and they don?t need to be continuously verified the way you do to access your mobile device or email.
Better keep your memory sharp, at least a little while longer.

A. Finally, it has taken a giant leap forward. B. All of the factors pushing online education toward the mainstream of higher education are now crashing together. C. Over the past few years, he has been teaching himself programming. D. In other words, Coursera?s approach is a long way from a simple online video lecture. E. Yet the most exciting promise of their company and the like is the role they might play in improving education for the poor around the world. F. Ng?s course in machine learningattracted 104,000 enrollees around the world.
A School That Can Educate Us All
Christos Porios, 16, lives in a small Greek city. “My mother?s a teacher and my father?s a mechanic,” he explains, adding that neither is knowledgeable about computers — especially compared with him. 67 Porios was taking a free class in machine learning offered by Andrew Ng, a professor at Stanford University, over an online platform Ng developed with his colleagues. Drawing on what he learned, Porios was able to participate in the International Space Apps Challenge, a virtual hackathon (编程马拉松) using data from NASA and other government agencies.
If one teenager in one small city can become a genius hacker through an online course, does it mean the world has changed? We have been hearing about the potential of online education for decades. 68 A number of online education platforms have appeared, featuring professors from top universities offering free courses.
69 Ng was amazed. “It would take me 250 years to teach this many people at Stanford,” he says. And so, just one month into the course, Ng and his Stanford colleague, Daphne Koller, decided to leave their faculty posts(教职) and dive into online teaching full-time. In April, they launched their company, Coursera, with a $16 million round of venture funding. So far, it has managed to team up with 35 colleges in nine countries.
To Ng and Koller, Coursera?s mission is simple and yet grand. That is to teach millions of people around the world for free, while also transforming higher education.
According to Ng, the world?s top 20 universities enroll only about 200,000 students. There are million more who could participate in classwork at the higher level, but most of them are far from any of the leading universities. 70
Koller says Coursera?s total registration has hit 15 million. Porios, the young Greek, is only one of those registrants. His hope is to study in Germany or England someday. He is even toying with the idea of taking classes at MIT or Stanford —but this time in person. IV. Summary Writing
Directions: Read the following passage. Summarize the main idea and the main point(s) of the passage in no more than 60 words. Use your own words as far as possible.
