In the United States，every year, Thanksgiving Day is on the fourth Thursday of November．People in Canada also celebrate Thanksgiving Day. But because Canada is in the north of the United States，so it is colder and the harvest comes earlier in the year．In Canada，people have Thanksgiving Day on the second Monday of October．

    The harvest brings a lot of food to people．On Thanksgiving Day people in Canada and America like to have a big meal with their friends and family just like what Chinese people do at Mid-Autumn Festival．Many Canadians and Americans put flowers，vegetables and fruits around their homes．

    At a Thanksgiving Day dinner, many Canadians and Americans will eat turkey, potatoes and pumpkins pie．These are food like the food of many years ago．They are saying “Thank you” for the harvest that comes every year．

    Control your house from your hand. Download(下载)a film in just one second. Print a mobile phone at home. These are just a few technologies that we may see this year. Let's take a look at a few of them.

    Smart Screens

    This year, smart screens will be big news. They use AI technology and look like an iPad. Google Home Hub is a good example. It is a smart screen that people can use for everything from looking up video recipes(菜谱)to looking at family photos. You can also connect your other smart devices(设备)to Home Hub through the Internet. You can turn on lights or the TV simply by speaking to Home Hub or touching a button(按钮)on the screen.

    5G Internet

    How fast is your mobile phone network? After 3G and 4G, 5G is on the way. According to Science Daily, it is hoped that the US will test 5G this year, while the UK will do so in 2020. China has already tested 5G in some parts of Beijing and Hebei.

    5G is very fast. Its speed is about 10 to 20 times faster than networks now, the BBC noted. You can download a whole film in just one second with 5G. This used to take a few minutes with 4G networks.

    3DMetal Printing

    3D printing isn't new. It first came out in the 1990s. But it isn't commonly used in everyday l life. 3D printers are expensive, each costing thousands of dollars. In addition, they can only print plastics and other basic materials.

    But now, some 3D printers can print metal. HP can print some small metal parts for cars, such as key rings and gear sticks(操作杆). People can use 3D printing to make things like toys. But what if people could print these at home? This would help save time and money. More people might think about buying their own 3D printers.

    Music and Art will enter the Entrance Exam for the high school in Jiangsu. Without music, life would be a mistake. Music is a big part of our lives. But in recent years, some US schools have cut music classes to control budgets (预算).

    For example, Chicago public schools hurt arts education when it fired (解雇) over 1,000 teachers. Among them, 10 percent of the teachers taught art or music, according to The Washington Times. In fact, this is not just a problem in the US. In other countries, such as China and the UK, music classes are not thought to be as important as ones like science, math and history. That's partly because music is not seen as a very important life skill, and it isn't tested. Many students are busy with schoolwork, so parents and students choose to focus on subjects that are tested more often.

    However, learning music is beneficial (有益的) in many ways.

    When playing music, you need different abilities to work together. It is not as simple as it looks, according to Kenneth Guilmartin of Music Together, an early childhood music development program. For example, when playing the piano, people see music notes and decode (解码) them in their brains. They also use their fingers to make sounds. You need to deal with all these things at the same time.

    Music has a special connection with science as well. You can see that many scientists are good at playing music: Einstein played the violin, and German physicist Max Planck was talented in playing the piano.

    The Spring Festival is celebrated not only in China but also in other parts of the world. The traditional holiday is the most important to Chinese both home and abroad.
