Facebook is an American online social media and social networking service. The Facebook website was launched on February 4, 2004, by Mark Zuckerberg, along with fellow Harvard College students and roommates.
The founders had limited the website's membership to Harvard students at first; however, later they expanded it to various other universities, and eventually to high school students as well. Since 2006, anyone who claims to be at least 13 years old has been allowed to become a registered (注册了的) user of Facebook, though differences exist in the youngest age requirement, depending on local laws. Facebook has more than 2 billion monthly active users as of June 2017. As of April 2016, Facebook was the most popular social networking site in the world, based on the number of active user accounts.
Facebook may be accessed by a large range of desktops, smartphones over the Internet and mobile networks. After registering to use the site, users can create a user profile (简介) showing their names and so on. Users can add other users as "friends", exchange messages, post photos and so on.
Facebook makes most of its income from advertisements which appear on screen, marketing access for its customers to its users.

When I was 25 years old, I had a big dream in my mind. I wanted to travel around Africa with my 1. So I left my hometown with great confidence and 2 in Cape Town, not really sure what to do next. 3, before my trip actually started, I 4 a kind, old Nigerian man. He gave me the best travel 5 I had ever received: “BE LIKE A STUDENT ON YOUR WAY AROUND THE WORLD.”
It sounded 6, but it really changed my idea about traveling. He helped me 7 that travel is about learning and observing 8. It's far too easy to go into a (n) 9 country and believe your ways are better.
“But if you study, ask questions, and try to 10 the locals, you'll have far richer 11,” he promised me.
When I was on my tour way to Cancún, I was 12 a tourist. I only stayed there for a week to see the 13 and places of interest and then left. The culture didn't 14 me. I left the cities and towns without really 15 anyone or anything that existed in those places to which I had 16 a visit.

By the time the British adventurer Ash Dykes reached Chongqing 178 days after starting to trek (长途跋涉) along the Yangtze River from its source to the sea, the most difficult part of the journey was over. Dykes had completed about 2,430 miles, and all he needed to do was cover the next 1,550 miles in 187 days or less to complete the whole journey.
On August 26 last year, a three-man team, including two guides and a horse, hit the road at the starting point, the source of the Yangtze River in the south of Qinghai Province. Then at different times for the next two months, different people had come to join them.
In order to cross the plateau (高原) and mountains in good weather, the journey was planned to start in summer. However, because of the problems in preparations, Dykes arrived in Qinghai in late August as the days were becoming shorter and colder. Not wanting to wait for another year, he decided to continue.
Within a few days three of the adventurers experienced serious high altitude sickness (高原反应). In the mountains, the team had to light fire to scare off bears, and once they had been followed by a group of wolves for two days. They were forced to quit the journey. In fact, Dykes has been walking alone since late October.
“The rest of the trip would be much easier,” Dykes said. He started from Chongqing on the second half of the journey on March 11. At the same time,he called on more people to join him in some parts of the trek as a way to encourage environmental protection.
“Travelling along the Yangtze River is not only a great act, it's also a chance to enjoy the true beauty and wonders of China, and attract people's attention to the environment and good work to protect it,” he wrote on his Weibo. “However, the kindness and warmth of the local people have struck me so much that it is they that make the journey unforgettable.”
Study after study shows the most important thing deciding the quality (质 量) of the education a child receives is his teacher. Teaching has become one of the most difficult jobs today. But what makes a great teacher?
Responsible teachers set high expectations for all students. They expect that all students can achieve in their classroom, and they don't give up on those who do poorly in study.
Great teachers have clear teaching goals. They have lesson plans that give students a clear idea of what they will learn, what the homework is and what the grading standard is. Homework has learning goals and gives students enough chances to practice new skills. At the same time, they are prepared and organized. They are in their classrooms early and ready to teach. They present lessons in a clear way and instill (逐渐灌输) a hunger in their students to learn more on their own.
To become great teachers, they should engage (吸引) students and get them to look at problems in all kinds of ways. They use facts as a starting point, not an end point; they ask “why” questions, look at all sides and encourage students to imagine what will happen next. They ask questions frequently to make sure students are following along. They try to engage the whole class, and they don't allow a few students to control the class. They keep students active with many different and lively ways.
Great teachers have strong relationships with their students and show that they care about them as friends. Great teachers are warm, kind, energetic and caring. Teachers with these qualities are known to stay after school and make themselves available to students and parents who need them. They often communicate with parents. They reach parents through parent-teacher meetings and frequent written reports. They will pick up the telephone to call a parent if they are concerned about a student.
