3 . Hadi Partovi, founder of Code. org believes every student should learn the basics of computer science just like they do math, physics, or biology, regardless of what they want to do in the future. The expert says knowledge about the subject is important to understand how the world around us works and compares it to learning about photosynthesis (光合作用), even though not every student is going to be a botanist. To spark students’ interest, he created the “Hour of Code”, which introduces the world of computing to anyone, from ages 14 to 104, in a fun, interactive manner. Observed annually during Computer Science Week, the event now draws tens of millions of kids from over 180 countries.
The “Hour of Code”, which can be scheduled anytime during Computer Science Week, begins with an introductory video on computer science. Participants can then select from hundreds of fun assignments that are sorted by both grade level and coding experience. Though each project is designed to last just sixty minutes, beginners can deal with as many challenges as they desire.
To help introduce computer science in classrooms on a more regular basis, Code. org has also developed a catalog of online courses that can be incorporated in a school’s regular curriculum. Since the nonprofit began offering the courses in 2013, over 704, 000 teachers have signed up to teach introductory computer science to over 22 million students worldwide.
Thanks to the efforts of the pioneer, about 40 percent of US schools now offer computer science as a subject. The numbers are even higher — an impressive 70 percent — if after-school offerings such as robotics clubs are included. Even more encouraging, eight years ago, just 19,390 students took an Advanced Placement Computer Science exam. By the spring of 2017, the number had jumped 415 percent to 99,868.

4 . How to Be Creative
Most of us think that creativity is a quality (品质) belonging only to artists, writers, or dancers, rather than ourselves.
Get out of your comfort zone
We eagerly accept the familiar and fear the unknown. Break out of your usual patterns and welcome creativity into your life. As said earlier, the human brain was designed to recognize patterns.
Try different things
If you always do what you’ve always done, you’ll always get what you’ve always got. We are creatures of habits and routines, and creativity hates routines (常规). If you usually drive to work, take the subway for a few days.
Having a great idea is not enough, you must work to make it a reality. Have you ever seen a new product and realized that you thought of the same thing long ago? Yet someone else is making money with “your” idea.
A.Take action |
B.Seek several options |
C.Think from the other person’s point of view. |
D.If you normally eat in the office, have lunch under a tree. |
E.We continue to create patterns for almost everything we do. |
F.The truth is that we are all born with the ability to be creative. |
G.We all have great ideas sometimes, but only a few people turn their ideas into realities. |
5 . Reading can be a social activity. Think of the people who belong to book groups. They choose books to read and then meet to discuss them. Now, the website Book Crossing.com turns the page on the traditional idea of a book group.
Members go on the site and register (登记) the books they own and would like to share. Book Crossing provides an identification number (识别码) to stick inside the book. Then the person leaves it in a public place, hoping that the book will have an adventure, traveling far and wide with each new reader who finds it.
Bruce Pederson, the managing director of Book Crossing, says, “The two things that change your life are the people you meet and books you read. Book Crossing combines both.”
Members leave books on park benches and buses, in train stations and coffee shops. Whoever finds their book will go to the site and record where they found it.
People who find a book can also leave a journal entry describing what they thought of it. E— mails are then sent to the BookCrossers to keep them updated about where their books have been found. Bruce Pederson says the idea is for people not to be selfish by keeping a book to gather dust on a shelf at home.
Book Crossing is part of a trend (趋势) among people who want to get back to the “real” and not the virtual (虚拟).The site now has more than one million members in more than one hundred thirty—five countries.

9 . To help you understand what 5G is, and what it means to you, we’ve put together a handy guide here.
What is 5G?
5G will use new higher radio frequencies to send out data, which are less cluttered(挤了)and carry information much faster. While these higher bands(频段) are faster, they don’t carry information as far. That’s to say, smaller multiple input and output antennas (天线)will be used—promoting both signals and capacity(容量).
Why is it better than 4G?
5G is expected to be faster than 4G, with some firms claiming it could be as much as 100 times quicker. The fastest 4G networks can deliver 传输)peak(峰值)download speeds of around 300 Mbit/s.
Finally, 5G will have a larger capacity, meaning networks will be able to deal with several apps at once. Generally, this should mean that devices have a faster, more stable connection.
A.How does 5G work? |
B.How will 5G affect you? |
C.5G is also expected to have a lower lag(延迟). |
D.5G is short for “5th generation mobile network.” |
E.In comparison, 5G could offer download speeds of over 1 Gb/s. |
F.Therefore, the similarity between 5G and 4G technology is huge. |
G.This means 5G will support up to 1,000 more devices per meter than 4G. |
10 . Central Park
Explore Central Park, one of the largest city parks in the world and one of the most famous symbols of New York. Let’s have a look at its main sights.
Central Park is New York’s largest city park and one of the biggest in the world, with an area of 843 acres (about 3.4km2). This park is home to man-made lakes, waterfalls, grass and wooded areas. You will also find the Central Park Zoo, among other attractions in this greenspace of New York.
Besides being the city’s primary green lungs, Central Park is also a favorite spot for many New Yorkers. It is perfect for sunbathing, going for walks, or doing any outdoor sports. Something that we found curious is seeing so many people running with their babies in prams (婴儿车).
On Foot or by BicycleTo get to know some of the wildest parts of Central Park we suggest walking. However, to get a general feel for the whole park, the best thing to do is hire a bicycle and enjoy the scenery.
If you decide to hire a bike, you will find lots of bike rental stores around Central Park that are not very expensive.
Open TimeFrom 7 a.m. to 10 p.m. on weekends.
From 6 a.m. to 8:30 p.m. on weekdays.
