1 . Located in the southeast of Canada and with a population of approximately 6 million, Toronto is a big and beautiful city, which has developed from a relatively unknown place over the past half century to the center of culture, trade and communication in Canada.
With its colorful ethnic mix, rich history and breathtaking buildings. Toronto offers non-stop adventures to the tourists. To get a sense of how big, various and magical Toronto is, the best place to start is the CN Tower. From this point, visitors can get a bird's-eye view of the city's amazing scenery and unique geography.
In addition to being an important center of culture, trade and communication in Canada, Toronto is also a major muti-ethnic city. It is the most populous city in Canada and its citizens come from countries around the world and from different kinds of ethnic backgrounds. Every day, in most places of the city, a hundred different languages can be heard on the streets, from Hindi to Greek to French. This, perhaps, explains why former Prime Minister Pierre Trudeau once said that Canada is a mosaic（嵌合体）of cultures and languages rather than a melting pot.
Street signs in Toronto are mostly in English. Weekly and daily newspapers are published in various languages, and the city hosts the successful international film festival each September. It is also home to a popular baseball team the Toronto Blue Jays. Toronto has something for everyone.
Moreover, Toronto has been rated one of the most livable cities in the world by United Nations Human Settlements Programme for many years. At the same time, Toronto is one of the safest, richest cities in the world with the highest standard of living.

2 . 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?

3 . Every week in China, millions of people will sit in front of their TVs watching teenagers compete for the title Character Hero, which is a Chinese-style spelling bee. In this challenge, young competitors must write Chinese characters by hand. To prepare for the competition, the competitors usually spend months studying dictionaries.
Perhaps the show’s popularity should not be a surprise. Along with gunpowder and paper, many Chinese people consider the creation of Chinese calligraphy(书法) to be one of their primary contributions to civilization. Unfortunately, all over the country, Chinese people are forgetting how to write their own language without computerized help. Software on smart phones and computers allows users to type in the basic sound of the word using the Latin alphabet. The correct character is chosen from a list. The result? It’s possible to recognize characters without remembering how to write them.
But there’s still hope for the paint brush. China’s Education Ministry wants children to spend more time learning how to write.
In one Beijing primary school we visited, students practice calligraphy every day inside a specially decorated classroom with traditional Chinese paintings hanging on the walls. Soft music plays as a group of six-year-olds dip brush pens into black ink. They look up at the blackboard often to study their teacher’s examples before carefully attempting to reproduce those characters on thin rice paper. “If adults can survive without using handwriting, why bother to teach it now?” we ask the calligraphy teacher, Shen Bin. “The ability to write characters is part of Chinese tradition and culture,” she reasons. “Students must learn now so they don’t forget when they grow up.” says the teacher.
1. What can we learn about the Character Hero?| A．It’s open to people of all ages and all walks. |

6 . An aircraft carrying personal protective equipment donated by China, along with U.S.-purchased medical supplies, arrived in New York on March 29.
The plane is the first in a series of flights over the next 30 days organized by the White House to help fight the coronavirus, the White House said. Most of the purchases are from Asia including Malaysia and Vietnam.
The Chinese Embassy in the U.S. retweeted a report from Axios, which said that 12 million gloves, 130,000 N-95 masks, 1.7 million surgical masks, 50,000 gowns, 130,000 hand sanitizer units, and 36,000 thermometers from China have arrived in the United States.
Along with the goods, Chinese company Huawei donated 10,000 masks, 20,000 articles of protective clothing, 10,000 gloves and 50,000 goggles to New York state.
Governor Andrew Cuomo confirmed the donation and thanked Huawei on Twitter.
The plane was funded by the Federal Emergency Management Agency. It landed at John F. Kennedy airport carrying gloves, gowns and masks for distribution in New York, New Jersey and Connecticut, three hard-hit states battling to care for a crush of coronavirus patients.
The airlift is a product of a team led by White House senior adviser Jared Kushner, which formed "Project Airbridge," a partnership between large U.S. healthcare distributors such as Mekesson Corp, Cardinal, Owens & Minor, Medline and Henry Schein Inc, and the federal government.
The flight from Shanghai was the first of about 20 flights to arrive between now and early April, according to the White House. Additional flights will carry similar gear from China, Malaysia and Vietnam.

7 . Thanks to this new hands-free suitcase, carrying around heavy luggage may soon become a thing of the past. Designed by an Israeli company NUA Robotics, this “smart” suitcase will follow you everywhere you go.
The carry-on suitcase, currently a prototype, connects to a smart phone app via Bluetooth. It has a built-in camera sensor that can “see” you and follow you around on flat surfaces like airport floors. It comes with an anti-theft alarm to prevent someone carrying it away when you’re not looking and it has a backup battery that you can use to charge all your devices.
“It can follow and carry things for people around while communicating with their smart phone, and avoiding obstacles,” explained Alex Libman, founder of NUA Robotics. “We’re combining sensor network, computer vision, and robotics. So if you download our app, press the follow-me button, the luggage recognizes the specific user and knows to follow and communicate.”
NUA is still testing the device and trying to improve features like speed and customization, but they hope to make the suitcase available to customers in a year’s time. If it proves successful, they want to use the Bluetooth pairing technology to automate lots of other devices, like shopping carts at the supermarket. These devices are especially meant to be useful to the physically disabled and elderly. “Any object can be smart and robotic,” Libman said, “We want to bring robots into everyday life.”
The Israeli tech company made it clear that the finished product will look just like a regular suitcase. They’re planning to partner with a carry-on luggage maker, since the device that makes it “smart” weighs just 2.5 pounds and can be fitted on old-fashion luggage.
With NUA’s smart suitcase, carrying round heavy luggage isn’t a burden. But how their invention will handle tough obstacles like stairs? It will be interesting to wait.

8 . If humans ever hope to live on the Mars, the settlers will need to produce a series of organic compounds (有机化合物), from fuels to drugs, which are too expensive to ship from Earth.
Chemists from University of California, Berkeley, and Lawrence Berkeley National Laboratory (Berkeley Lab) have a plan for that.
For the past eight years, the researchers have been working on a system combining bacteria and nanowires (细菌和纳米线) that can catch the energy of sunlight to change carbon dioxide (CO,) and water into building blocks for organic things. Nanowires are thin wires about one-hundredth the width of a human hair, used as electronic parts, and also as solar cells.
“On Mars, about 96% of the atmosphere is CO2. Basically, all you need is these nanowires to take in the solar energy and pass it on to these bacteria to do the chemistry for you,” said project leader Peidong Yang, professor of chemistry and the S.K. and Angela Chan Distinguished Chair in Energy at UC Berkeley. “For a deep space task, you care about the weight, and biological systems have the advantage that they self-reproduce: You don’t need to send a lot. That’s why this version is highly attractive.”
The only other requirement, besides sunlight, is water, which on Mars is relatively more than enough in the polar ice caps and likely lies frozen underground over most of the planet, said Yang.
It works like photosynthesis (光合作用), which plants naturally employ to change CO2 and water into carbon compounds, mostly sugar and carbohydrates. Plants, however, have a quite low efficiency (效率), usually changing less than one-half percent of solar energy into carbon compounds. Yang’s system is comparable to the plant that best changes CO2 to sugar, which is 4～5% efficient.
1. What is the function of the new biological system?| A．Reducing air pollution on Mars. |
| B．Carrying many organic things to Mars. |

9 . As most of you know, I don’t like running. I never go jogging, and I wouldn’t run a marathon even if I was paid for it. One thing that would make me run for my life would be if there were several hundred bulls running after me.
That’s exactly what people from all over the world are coming here to do tomorrow. I’m at the annual San Fermin Fiesta in Pamplona, Spain. This festival began in the Middle Ages, and has grown in popularity ever since. It lasts for a week in July, when the city is changed into an ocean of red and white, the official colors of the festival.
Before the bullring (斗牛场）was built, bull fights were held in a large square in the city. The custom of running ahead of the bulls started when the bulls had to be moved from the outskirts（市郊）of the city to the bullring. Some of the customs have changed over the years, but certain things are still the same.
Anyone who wants to take part in the run has to enter the special area by 7:30 am. The gates are then closed, and they won’t be opened to let you leave after that. At just before 8:00 am, the runners ask the statue of San Fermin to protect them. At eight o'clock, two fireworks are fired. With the first firework , the gates of the bull enclosure（围场）are opened, and with the second, the bulls are set free to run. They run after the runners down the length of the bull run, which is about 800 meters. The whole thing lasts about two minutes.
It sounds easier than it is. You can’t just run straight ahead. The route goes up and down narrow streets, with few places for runners to hide except doorways of buildings. The end of the run, just before the bulls enter the ring, is one of the most dangerous places. People running with the bulls have fallen here, and have been injured.
Don’t worry if you’re reading this, Mom. No one under the age of 18 is allowed to take part. I’ll be watching from the safety of the balcony!
