19．One day，I was invited to an important event，and I wanted to wear something special for it．I looked through my suitcase but couldn't find anything to wear．I was lucky to be at the technology conference then，and I had access to 3D printers．So I quickly designed a skirt on my computer，and I loaded the file on the printer．It just printed the pieces overnight．The next morning，I just took all the pieces，assembled them together in my hotel room，and this is actually the skirt that I'm wearing right now．
It wasn't the first time that I had printed clothes．For my senior collection at fashion design school，I decided to try and 3D print an entire fashion collection from my home．The problem was that I hardly knew anything about 3D printing，and I had only nine months to figure out how to print five fashionable looks．I always felt most creative when I worked from home．I loved experimenting with new materials，and I always tried to develop new techniques to make the most unique textiles for my fashion projects．
One summer break，I came here to New York to do practice at a fashion house in Chinatown．We worked on two incredible dresses that were 3D printed．They were amazing．But I had a few problems with them．They were made from hard plastics and that's why they broke easily．The models couldn't sit in them，and they even got hurt from the plastics under their arms．So now the main challenge was to find the right material for printing clothes with．I mean the material you feed the printer with．
The breakthrough came when I was introduced to Filaflex，which is a new kind of printing material．It's strong，yet very flexible．And with it，I was able to print the first garment，a red jacket that had the word"freedom"printed into it．And actually，you can easily download this jacket，and change the word to something else，for example，your name or your sweetheart's name．So I think in the future，materials will be better，and they will look and feel like fabrics we know today，like cotton or silk．

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）C
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 A number of online education platforms have appeared，featuring professors from top universities offering free courses．
（69）F 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 35colleges 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 20universities 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）E
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．

16．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 45volunteers as they read through a list of 75acronyms 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 biometric system （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 verification could 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．

15．At first glance Esther Okade seems like a normal 10-year-old．She loves dressing up as Elsa from"Frozen"，playing with Barbie dolls and going to the park or shopping．But what makes the British-Nigerian youngster stand out is the fact that she's also a university student．
Esther，from Walsall，an industrial town in the UK's West Midlands region，is one of the country's youngest college freshmen．The talented 10-year-old enrolled at the Open University in January and is already top of the class，having recently scored 100% in an exam．
"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？B
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 thatC．
A．Esther thinks her parents expect too much of her
B．Esther cannot adapt herself well to college life
C．Esther asked to go to university even earlier
D．Esther dislikes being taught at home
58．What might be a main factor that has led to Esther's being a maths genius？A
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 whoA．
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．

Delivering Food by Drone
A Singapore restaurant plans to use drones（遥控飞机） to transport food and drinks from the kitchen to a wait station near customers'tables．
Infinium Robotics，the Singapore company that's developing the drones for restaurant chain Timbre，has spent the past two weeks testing the technology at the restaurant before it opens each night（21）for business and hopes to have it in place by the end of the year．
But how does the drone know where to hover （盘旋）？What if someone bumps into the drone or is standing in its way？"There's no chance at all（22）that it will hit anything，"says Infinium Robotics chief executive Junyang Woon．
The drones automatically charge while（23）waiting  （wait） in the kitchen．（24）After  the chef puts an order on the drone，he hits a button on a keypad and the drone automatically flies to one of two wait stations．Sense-and-avoid technology （25）built （build） into the drone won't allow it to land at the wait station if anything is in its way．The drones are equipped with sonar （声纳系统） and an infrared sensor （红外线传感器），too．
A waiter then removes the food or drink from the drone and hits a button （26）that/which  sends it back to the kitchen．The drones，weighing a little over five pounds，（27）can carry just over four pounds of food．Infinium Robotics is working on a model that will carry twice as（28）much（much） food．
"Its job is to help the waiters to reduce some of their boring tasks，"Woon said．"If they let the robots （29）do （do） the job，they can concentrate on interacting with customers to bring about higher customer satisfaction and dining experience．"
Since it drew recent media attention，Woon（30）has heard （hear） from resorts and restaurants in 10 countries，including the United States．

Success Is On The Other Side of Failure
Everybody wants success．Some people aim for it； others just talk about it．（36）DBut the truth is that it's closer than you think．It's just on the other side．You have to want it enough，and be willing enough to get it．
It has no excuses．Fear is your biggest obstacle（障碍）．It will cause you to make decisions that may seem"right"at the time．（37）EYou either get it or you don't．The minute you find a reason not to take another step towards success is the moment you stop being successful．In the symphony of success，excuses are just noise．
It is on the other side of obstacles．Everyone faces challenges；different ones at different times．We all handle the same challenges differently； we all have different results．It's how you handle each one and what you do with the results that count．（38）GRemember，you're got to pass obstacles in order to succeed．
（39）BThey call it a ladder of success for a reason．You need to climb it in order to get somewhere．It's no tan escalator（自动扶梯）．You can't stand there and let it do the work for you．（40）AIt's going to take determination and commitment on your part to get up and over that wall．

A．You have to do the work yourself．
B．It takes effort，commitment and follow-though．
C．You'll be carrying a heavy load on your shoulders．
D．Often times it just seems like something too far out of reach．
E．But they're preventing you from actually getting over that wall．
F．Even if it works for other people，the same thing just doesn't work for us．
G．An obstacle is something you either find a way around or allow to stop you．
