    Human beings are the most intelligent of all animals because we are gifted with the ability to think and reason logically. Scientists and even common people with special intelligence have made a lot of inventions and contributions to modern lifestyle in the past. “Houses” have been the most popular area for discoveries and inventions in the past and even now.

    Many household items have been the result of inventions of people who desired better functioning of the existent products. Every individual has intelligence and if it is used properly for the right purpose it leads to invention of a new tool or device. Many new household inventions are made almost every day and there are specific companies, which particularly keep a record of all these inventions.

    A lot of inventions have been made recently in the household field. These products are patented(专利的) and have trade mark licenses. The patented sliding cinch is a very simple but effective method to prevent shoulder stress and injury for those who work before computers all day long. Vanity PC is a type of computer furniture that specifically hides all the computer wires and keeps a clean and good look. All the outdoor dust, mud and snow can be kept out of the house by installing(安装) the dirt drain(排水管) at the entrance of the door. Another important invention is the automatic toilet night-light, in which a small light starts when the lid of the toilet seat is opened and closes as soon as the lid is closed.

    These are some of the new household inventions invented mostly by common people. Thus, a variety of new household items are invented every day, which helps in a better functioning of household chores and in a more useful manner.

    Are you afraid of moving up to senior high school? It is a completely new experience, but you shouldn't worry. We've got a guide to help you.

    You're not alone. Remember that everybody else in your year is in the same boat. You may not notice it, but they're just as nervous as you are.

    Moving to senior high school is a chance, not a problem. Things are different, and all you need to do is to be polite and learn the new rules.

    The teachers will help. If you don't know what to do or are worried about something, then ask for help. Teachers are probably the best people to turn to, because they have experience in helping new students. Pay attention to what your teachers say.

    Everything changes. There are lots of differences between junior high school and senior high school. You will have your lessons with different teachers in different rooms. You will have homework for different subjects on different days, so make sure you get organised. Make sure you know which rooms your classes are in and which days you have your different subjects on.

Other points:

    If you've got an older brother or sister at the school, then ask them for advice.

    Be yourself! It sounds simple, but things will become better if you just act naturally.

    Having early nights makes a difference. You'll also find it easier to get up in the morning!

    Everyone looks forward to progress, whether in one's personal life or in the general society. Progress indicates a person's ability to change the way he is living at the moment. Progress must lead a better way of doing things. All these, however, remain true only in so far as people want to accept technology and move forward by finding new and more efficient ways of doing things.

    However, at the back of the minds of many people, especially those who missed the “good old days”, efficiency comes with a price. When communication becomes efficient, people are able to contact one another no matter where they are and at whatever time they wish to. The click of a button allows people miles apart to talk or to see each other without even leaving their homes. With the communication gadgets, such as mobile phones and ipads, people often do not take the effect to visit one another personally. A personal visit carries with it the additional feature of having to be in the person's presence for as long as the visit lasts. We cannot unnecessarily excuse ourselves or turn the other person off.

    With efficiency also comes mass production. Such is the nature of factories and the success of industrialization today. Factories have improved efficiency. Unskillful tasks are left to machines and products are better made and produced with greater accuracy than any human hand could ever have done. However, with the improvements in efficiency also comes the loss of the personal touch when making these products. For example, many handcrafts are now produced in a factory. Although this means that supply is better able to increase demand, now that the supply is quick and efficient, the demand might fall because mass production lowers the quality of the handicraft and it is difficult to find unique designs on each item.

    Nevertheless, we must not commit the mistake of analyzing progress only from one point of view. In fact, progress has allowed tradition to keep up. It is only with progress and the invention of new technology that many old products can be brought back to their old state. New technology is required for old products to stay old.

    It is people's attitude towards progress that causes the type of influence that technology has on society. Technology is flexible. There is no fixed way of making use of it. Everything depends on people's attitude. The worst effects of progress will fall on those who are unable to think again about their attitudes and views of society. When we accept progress and adapt it to suit our needs, a new “past” is created.

The Trip to Alishan in Taiwan

    It was the fourth day of our trip to Taiwan, bright but cold. After a good breakfast we put on our jackets and gloves, pulled on our hats and got into a car. We travelled for about two hours, up, and up, and up the mountain road.

    We finally arrived at the top of the mountain. It was Christmas Day. So imagine my joy to see icicles(冰柱)hanging form branches and the whiteness of the scenery. Indeed, it was my first Christmas in the northern hemisphere(半球)and, guess what? It even started snowing too. How amazingly exciting for me to have Christmas in my grandmother's hometown, and to experience icicles and snow. Alishan is really beautiful, especially seen form this dizzy height. After Sun parked the car, we got out and looked down through the trees. It hadn't snowed hard enough so there was no snow on the ground, just loads of pine needles. There was a most wonderful smell of pine sap(松液)drifting up to us form the ground. It was very quiet, except for the twittering of birds, and the odd car passing along the road. Quietness in Taiwan is something to treasure.

    Over the road was a small stall so we went over to it. They were selling some drink steaming hot in paper cups, too hot to hold immediately. We jumped around to get warm. There was a cool wind blowing up the side of the mountain, and the clouds above us were moving along quickly. I could imagine there was quite a strong wind blowing up there, so I was glad we were down on the ground! The drink cooled down fairly rapidly. I picked up my share and, wow, what a lovely smell was coming from it. It was the smell of ginger(姜).I took a sip. How delicious, and so this was ginger tea, which I had never tried before. It warmed my body so quickly that I could feel the heat travel right down to my fingers and to my toes. This was very good stuff. And then it was time to leave as we were going down to Hualian to attend a Buddha bi-bi, eat hot pot, and drink some Shaoxing rice wine.

    Huawei Technologies Co. displayed its much-anticipated in-house operating system Harmony OS on Friday, marking what some call the Chinese tech giant's biggest push yet to build its own software ecosystem for the era of the internet of things.

    The move is also expected to weaken the influence of the United States government's restrictions on Huawei using Google's Android operating system in smartphones, analysts said.

    Yu Chengdong, CEO of Huawei's consumer business group, speaking in Dongguan, Guangdong province, said it is difficult to deliver a smooth experience across different devices with the huge amount of codes involved in the Android and Linux operating systems. Linux is an open-source operating system widely used in personal computers and other hardware.

    "Harmony is a next-generation operating system designed to address the challenge," Yu said, adding that it will be able to support a wide range of application situations, including smart TVs, automobiles and wearables.

    The internet of things refers to a network of devices and other objects that can connect with each other and exchange data.

    Yu said the US government's restrictions have accelerated the company's marketing of the system, which now has about 4,000 employees working on it.

    The senior executive said Harmony can be used in its smartphones. But Android is still Huawei's preferred choice for handsets if the company is allowed to use it.

    "But when Android is not available, Harmony can be applied immediately to smartphones. Harmony is ready," Yu added.

    Jia Mo, an analyst at market research company Canalys, said even if Huawei does not use Harmony in its smartphones in the short term, its smartwatches and smart TVs can be equipped with Harmony to widen its use and accumulate more experience in building an ecosystem.

    "Also, more importantly, Huawei chose to build Harmony into an open-source operating system and allow it to be compatible with Android. Thus Harmony will be more accepted by current Android users. This will prevent Huawei from repeating the fate of Microsoft in promoting smartphone systems," Jia said. Microsoft failed to popularize the use of its Windows system in smartphones years ago.
