What do you know about the Northern European country of Finland（芬兰）? You may have heard of the Northern Lights(极光)and Nokia? Today Finland is also a world leader in making mobile games. The popular games Angry Birds and Clash of clans（部落冲突）are both from Finnish companies.

    Finland is not a very big country. How can it make so many world-class games?

    Innovation(改革，创新)might be the first reason. Chinese President Xi Jinping visited Finland this month. He spoke very highly of the innovation of the country. Finland gives money to help start-up companies. It even builds technology bases for them. There are now around 290 game companies in Finland.

    Finnish mobile games also stand out(突出，超群) because of the country's special Northern European art style. The style is mainly about being simple. It's a tradition of Finnish design. You many also see it in clothes, furniture and even buildings. In the game Angry Birds, the birds and pigs look very simple but cute at the same time. They easily interest the players.

Information Card

    Have you ever counted the number of digits (数字) in your mobile phone number? Your number has 11 digits. You may sometimes find it hard to remember your number. That's because China has the longest mobile phone numbers in the world. Why is that?

    The 11 digits can be divided into three parts. Each part has a different meaning. The first three numbers tell you which mobile phone service company it is. For example, 135 is for China Mobile Communications

    Corporation and 188 is for China Unicom. The fourth to the seventh digits tell you where the number is registered (注册). And the last four digits are random (随机的).

    The main reason for using 11 digits is that we have the largest population in the world. We once had 10 numbers. But as our population grew, there were not enough numbers for us to use. So we began to use 11 digits starting from 1999. Eleven digits can be used to make tens of billions of mobile phone numbers. That's enough for each person to have seven or eight phone numbers to use in China.

    And mobile phone numbers can be recycled. Usually, the service company will reuse a canceled number after three to six months. If you call a number that you haven't contacted for a long time, you may find that its owner has changed.

    Besides China, Britain and Japan also use 11-digit mobile phone numbers. But their numbers always start with 0. So they cannot create as many numbers as we can. Countries like the United States, Australia and India use phone numbers with 10 digits. Canada's mobile phone numbers are perhaps the shortest in the world: they use seven digits.

    Young children don't have the skills or knowledge to stay safe in heavy traffic. The following tips (忠告) will be helpful for you to keep your children safe in heavy traffic. Children learn about road safety by watching others. As parents, make sure that you always set good examples. Your children will follow you and think it's OK to do like you. Teach your children to pay attention to traffic lights when you cross the road together with them. This helps them understand when it's safe to cross. Make sure that you walk between your children and traffic, and hold their hands all the time.

    When your children are a little older, you can start to tell them the importance of traffic knowledge. Let them start to understand the reasons why they need to be so careful. Talk with them about road signs and traffic rules.

    Ask your children to play in a safe place. Never let them ride bikes on the road without an adult present at rush hours.

    The most important thing you can do is to keep your children from getting hurt, so parents encourage them to follow traffic rules. After knowing about traffic rules, they'll volunteer to obey them. In this way, they'll be careful enough to keep themselves away from danger.

Mechanical Engineering

    Do you like to build with blocks? Have you ever wondered how planes stay in the air? Do you like to design and create new things? If you do, a career(职业）in mechanical engineering might be right for you！

    A mechanical engineer is responsible for coming up with and designing mechanical systems. Mechanical systems can include machine design, heating and cooling equipment, and product design.

    Mechanical engineers are in high need right now. There are a lot of job openings for mechanical engineers, but there aren't enough people to fill those jobs. Because there is a high need for engineers and the work requires specialized knowledge, engineers get paid more than some other careers.

    To be a mechanical engineer, you need to graduate from college with a bachelor's(学士)degree. In college, you will learn problem solving and critical thinking skills.

    Problem solving is very important in the field of mechanical engineering. To come up with the best solution to a problem, mechanical engineers need to think in different ways. They also need to be creative, because they may need to make something that's never been made before. Paying attention to details(细节)is important as well. Many designs depend on a lot of little details.

    Mechanical engineers also need to be able to use different tools, such as calculators, high-speed cameras, and computers. There are many computer programs mechanical engineers use to create designs, run scenarios(方案), and do research.

    As with many other jobs, mechanical engineers should be able to meet deadlines(期限)and work well with other people. Some jobs can be done with just one person, but more often mechanical engineers work on a team to complete a project. If an engineer cannot manage his or her time well and misses a deadline, the whole team gets delayed(拖延).

    Some engineers work in an office, and some travel to different worksites while a machine or product is being built, so they can help solve any problems.

    Mechanical engineering takes a lot of thought. It is a great career for people who like to make objects and machines work, solve problems, and be creative！
