1 . Most online fraud(诈骗) involves identity theft Passwords help. But many can be guessed. Newer phones, tablets, laptops and desktop computers often have strengthened security with fingerprint and facial recognition. But these can be imitated. That is why a new approach, behavioural biometrics(行为生物识别) is gaining ground.
It relies on the wealth of measurements made by today’s devices. These include data from sensors that reveal how people hold their phones when using them, how they carry them and even the way they walk. Touchscreens, keyboards and mice can be monitored(监测) to show the distinctive ways in which someone’s fingers and hands move. These features can then be used to determine whether someone attempting to make a deal is likely to be the device’s habitual user.
“Behavioural biometrics make it possible to identify an individual’s unique motion fingerprint”, says John Whaley, head of Unifyid, a firm in Silicon Valley that is involved in the field. When coupled with information about a user’s finger pressure and speed on the touchscreen, as well as a device’s regular places of use—as revealed by its GPS unit—that user’s identity can be pretty well determined.
Used wisely, behavioural biometrics could be a great benefit. In fact, Unifyid and an unnamed car company are even developing a system that unlocks the doors of a vehicle once the pace of the driver, as measured by his phone, is recognized. Used unwisely, however, the system would become yet another electronic spy on people’s privacy, permitting complete strangers to monitor your every action, from the moment you reach for your phone in the morning, to when you throw it on the floor at night.

4 . While some customs like setting off fireworks and counting down the last few seconds seem universal, many countries have their own unique New Year’s Eve traditions.
Denmark: Break plates
A Danish tradition is to throw plates and dishes against friend’s and neighbor’s front doors. It’s a bit of a popularity contest as the bigger the pile of broken china is the next morning, the more friends and good luck you’ll have in the coming year.
Germany: Pouring lead
In Germany, people melt small pieces of lead in a spoon over a candle, then pour the liquid into cold water. The shapes from the lead pouring are supposed to reveal what the year ahead will bring. If the lead forms a ball, luck will roll one’s way, while the shape of a crown means wealth; a cross means death and a star will bring happiness.
Spain: Twelve grapes of luck
In Spain, one New Year’s tradition is to eat 12 grapes, one for each month of the coming year, to secure prosperity (繁荣). You need to eat one grape with each bell strike at midnight. The tradition dates from 1909 when farmers in Alicante came up with this idea to sell more grapes after an exceptional harvest.
Philippines: Round food, round clothes, round everything
In the Philippines, the start of the new year is all about the money. The locals believe that surrounding themselves with round things (to represent coins) will bring money or fortune. As a result, clothes with dots are worn and round food is eaten.

5 . Learning a second language is difficult at any age and it only gets harder the longer you wait to open that dusty French book. Now, in a new study, scientists have pointed the exact age at which your chances of reaching fluency（流利）in a second language seem to rise： 10.
The study, published in the journal Cognition, found that it's "nearly impossible” for language learners to reach native-level fluency if they start learning a second language after 10. But that doesn't seem to be because language skills go downhill “It turns out you're still learning fast. It's just that you run out of time, because your ability to learn starts dropping at around 17 or 18 years old,“ says study co-author Joshua Hartshorne, an assistant professor of psychology at Boston College.
Kids may be better than adults at learning new languages for many reasons. Children's brains are more plastic than those of adults, meaning they're better able to adapt and respond to new information. "All learning involves the brain changing,“ Hartshorne says, “and children's brains seem to be a lot more skilled at changing. "
These findings may seem discouraging, but it was heartening for scientists to learn that the critical （关键的）period for fluent language acquisition might be longer than they previously thought. Some scientists believed that the brief window closes shortly after birth, while others stretched it only to early adolescence. Compared to those estimates, 17 or 18 when language learning ability starts to drop off——seems old.
“People progress better when they learn by immersion （沉 浸）rather than simply in a classroom. And moving to a place where your desired language is spoken is the best way to learn as an adult. If that's not an option, you can create an immersive environment by finding ways to have conversations with native speakers in their own communities," Hartshorne says. By doing so, it's possible to become conversationally fluent——even without the advantage of a child's brain.

6 . Have you ever wondered if you see the same colours as other people? Most people know what blue is when they see it. They call it "blue” because they were taught the word and connected it with what they saw. But how do you know what you see as blue isn't someone else's red?
The ability to perceive （感知）different colours is up to receptors （接受器）in our eyes. Light waves hit these receptors and they react depending on which colour the light is, sending signals to the brain. The brain then reads these signals to determine which colour light the eyes are receiving.
Some people's receptors are more developed than others. The inability of the receptor to feel the light waves correctly means that some people cannot tell the differences between similar colours. Those with more developed receptors can see more colours. We sometimes hear people having an argument about whether something is dark blue or black. It might be because one person has stronger receptors to feel the light than another.
In the past, most scientists would argue that everyone saw colours in the same way. However, research was conducted on monkeys, in which their receptors were changed. This enabled them to see more colours than usual. Normally monkeys can only see blue and green, but the change allowed them to see red. Their brains automatically got used to new colours. This suggests that our brains may find new colors of the things we see. Colours could be a very personal experience , unique to everyone.
So, the next time you talk about your favourite colour, just remember if yours is blue and your friend says red, you two might actually be thinking about the same colour. What if everyone in the world has the same favourite colour, but just calls it different names?

7 . One of the most important creations of science is the invention of the lighthouses. Lighthouses help in a number of activities such as marking of the dangerous coastlines and directing safe entries to the harbours. The following are some famous lighthouses.
The Jeddah Light
It is located in Saudi Arabia. This lighthouse has been constructed very beautifully and adorns a beautiful structure. The Jeddah Light was built in 1990. This lighthouse is considered as the tallest of the world reaching a fine height of around 436 feet.
The Les Eclaireurs Lighthouse
It is addressed as the “lighthouse at the end of the world”. The Les Eclaireurs Lighthouse is located on a small island east of Ushuaia, the southernmost city of the world. This lighthouse was built in 1920 and today it has become a very famous tourist attraction in Argentina. However, visits to this lighthouse can be made only by boat.
The Peggys Point Lighthouse
Lit in 1915, it is an icon and a popular monument of Canada. The Peggys Point Lighthouse has become a major tourist sight and is considered as one of the busiest attractions in the area of Nova Scotia. This lighthouse also fetches you a wonderful scenic drive and visiting here, you can indulge yourself in the beauty of nature.
The Slettnes Lighthouse
It is the northernmost lighthouse that is located on the mainland of Europe and is considered as one of the most famous lighthouses of the world. This lighthouse is mostly considered as the North Cape Light and is the top lighthouse of Europe. The Slettnes Lighthouse firstly began to light in 1905. Though it was highly damaged during the World War Ⅱ by the Germans, yet it was restored and lit again. This lighthouse is very classic as to its looks.

8 . The 15-day Spring Festival is the biggest holiday of the year for many Chinese to leave from their jobs to travel home and see their loved ones. But along with gathering come a lot of traditions aimed at making sure the year ahead is lucky and happy.
Here are some key dos and don’ts that many Chinese follow before and after the Lunar New Year.
DOs
Set off fireworks
The more fireworks or firecrackers you set off, the better.
Not only do you light up the night sky with a symphony of color, but the loud banging sounds are thought to scare off evil spirits.
Eat dumplings
Eating dumplings is a popular tradition in northern China because dumplings not only taste good but also look like pieces of gold.
Clean your home
Sweep, mop, vacuum, steam-do anything and everything to make sure your home is clean before the midnight on Lunar New Year eve. The aim here is to free your home from any bad luck that’s accumulated over the past year.
DON’Ts
Wash or cut your hair
Leave your hair as it is on the first day of the New Year.
The Chinese character for hair is the same first character in the word for prosperity(发达).
This means washing or cutting it off is seen as washing your fortune away.
Clean post-New Year
Cleaning of any kind on the first day is strictly forbidden.
You clean your home to avoid any bad luck before the New Year - now you want to be sure not to wipe, sweep or wash away any of the good luck that arrives after midnight.
Buy books
It’s bad luck to buy them during the 15-day Spring Festival.
The Chinese word for "book" (shū) sounds exactly the same as the word for "lose’"-so buying a book is considered an invitation to bad luck.
Also, avoid giving books as gifts to anyone, because it’d be like wishing bad luck upon them.
1. Why is the Spring Festival the best time for many Chinese people according to the text?| A．They can enjoy a lor of delicious dishes. |

9 . Faced with a declining population and workforce, Japan has been increasingly turning to robots for help. Over the years, the robots have carried out a large number of human tasks, including building products and providing care for the elderly.
However, the robots currently being used by companies, like Walmart and Amazon, are only able to perform single, repetitive tasks, such as stacking boxes. Model-T, on the other hand, has a wider range of movement and is able to hold, pick and place objects of several different shapes and sizes into different locations, making it ideal for convenience and grocery stores, which sell a large variety of items.
Model-T robots are operated from a distant location by human “pilots” wearing a virtual reality (VR) headset and special gloves, which allow them to feel the product the robot is holding in their hands and guide it to the right shelf.
The VR-controlled robots are ten times cheaper than automated robots, because they don’t require advanced programming and are easier to develop and maintain. And their easy-to-use controls require little training. Tomohiro Kano, a general manager in charge of development at FamilyMart, believes this will enable the chain to recruit workers who would typically not work in stores.
Though Model-T appears to be getting rapidly through the experiments, it is not quite ready to enter the workforce. Besides being a lot slower than humans, it is also only able to lift packaged items, and cannot get hold of things such as fruits and vegetables. The company is working to improve the weaknesses and hopes to introduce a faster, more skillful Model-T within the next two years. They believe that in addition to the stores, the robots could also be useful in hospitals, allowing doctors to do operations from remote locations.
1. What is one of the features of Model-T according to the text?| A．It works much faster than humans. | B．It can easily hold all kinds of objects. |
| C．It can be operated from a distance away. | D．It is harder to produce than an automated robot. |
| A．The low price of Model-T. | B．The easiness to operate Model-T. |
| C．The low-level programming of Model-T. | D．The strict training for maintaining Model-T. |
| A．Model-T is now being massively produced. |
| B．Japan’s workforce will be reduced by Model-T. |
| C．The weaknesses of Model-T have been overcome. |
| D．Model-T may be used in wider fields in the future. |
| A．Technology. | B．Economy. | C．Lifestyle. | D．Environment. |
10 . Are Superheroes Good Role Models?
Superheroes are everywhere. But what effect, if any, do superheroes have on our behavior? Some experts believe superheroes may have a particularly important influence on children.
Children have very limited control over many areas of their lives. Therefore, pretending to be a superhero allows a child to act out and process any anxiety that they have, and thereby overcome or reduce hidden fears, says Dr. Amy Bailey, a clinical psychologist.
Bailey adds, "The risk to superhero play is that sometimes children’s behavior can become out of control and turn into chaotic play as a child becomes completely lost in these roles." She advises parents to keep children away from more aggressive（暴力的）shows and to have children focus on "other positive characteristics of their favorite hero, such as their clever thinking and care of others". Concern over the possible effect of aggressive behavior has led to some schools banning（禁止）superhero play from the classroom.
Other psychologists（心理学家）share this concern. Some point to the change of the superhero over time, and are dissatisfied with modern images. "There is a big difference in the movie superhero of today and the comic book superhero of yesterday" says Sharon Lamb. She compares the selfish, playboy millionaire Tony Stark（Iron Man）to a superhero of the past, such as Superman. Superman she points out, had a real job as a newspaper reporter and was devoted to fighting injustice（不公平）. More recent characters such as Iron Man "take advantage of women, show off wealth, and show their manhood with high-powered guns".
Jeff Greenberg, a social psychology professor, has his own idea of modern superheroes. According to him, superheroes give children confidence and can deliver a positive moral message. Many superheroes-such as Spider-Man or Superman-use their powers to protect the weak. And more modern superheroes such as Daredevil, who is blind, and Charles Xavier（Professor）, who is disabled, bring diversity（多样性） and present positive images of disability.
