There are some special traditions in Hawaii. People there are very friendly and always welcome visitors. They give visitors a lei, a long necklace of beautiful fresh flowers. Men wear bright flowered shirts, and women often wear long flowered dresses.
     In Hawaii you may find some traditional Chinese  Japanese and Philippine holidays  Of course  many holidays are from the United States. People call Hawaii the Aloha State. Aloha means both “hello” and “good--bye”. It also means “I love you ”.

     Hawaiians earn most of their money from tourists, most of whom come from the mainland and from Japan. The families of the first people who came from the U.S. mainland own the important banks and companies. Japanese are  also starting business and buying more and more land.

    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.

Smile to the Lost Present

The one who has never gained something will never experience the pain of losing whatever that something is. That is pretty clear. But I consider the absence of the joy of "having" to be more miserable（痛苦的）than that of having lost something after having once had it.

When I was six years old, a lovely doll caught my eye. My mom refused to buy it for me, so I took a "job", my first, selling sweets in a park. Holding the doll which had been earned by myself, I was the happiest girl in the world. However, the doll ended up losing during a family trip. My tears couldn't bring it back.

In Grade Nine, my closest friend became estranged（疏远）from me. We had shared our innermost secrets with each other and supported one another through difficult times. At the time she kept me at a distance, I was very disappointed and even wished I had never known her. Accustomed to our friendship and her company, I didn't know what to do without her at one time.

Recalling the past, I'm not that sad about those lost treasures now. Instead, I am thankful for them for making my life colorful. I am proud of the persevering little girl who managed to acquire her coveted doll. And the memory of my ex-friend's warm smile continues to encourage me from time to time. How much would I have missed in life if I hadn't bought that doll or hadn't befriended that girl?

Experiences are of great importance to our lives. The world is so changeable that nothing is able to last forever. Nothing actually belongs to us except our own feelings. How much regret do you think exists in this unfilled blank which we create for ourselves when we give up on our reasonable wants just because of our fears of potential loss? For me, nothing could be more miserable than a risk-free but boring life in which you have the constant desire for something but have not the courage to make it your own!

Face peacefully the fact that, while the treasure itself is gone, the memories are still very much alive. Walk out of the shadow and accept the new present that is being delivered to you. Let these wonderful past moments shine like stars in the night sky.

Don't cry because it's over; smile because it once happened.
