Time is very important to us. When and by whom were the watches or clocks invented? Perhaps nobody knows. How could we tell time if there were no watches or clocks anywhere in the world? The sun was probably the world’s first “clock”, except in the far north, where the Eskimos live. There, it’s dark most of the winter, and light most of the summer. But in most of the world, people have used the sun for day. If you don’t have a clock that shows time, you still know that when the sun shines, it’s day, and when it’s dark, it’s night. The sun can not only tell you whether it’s day or night but also it’s morning, noon, or afternoon. When the sun is almost directly overhead, it’s noon. People who live near the sea know time from the tides（潮汐）. In the daytime, for about six hours, the water rises higher and higher on the beach. The same thing take place again at night. There are two high tides and two low tides every 24 hours. In some places in the world the wind comes up at about the same time every day or changes direction or stops blowing. In these places the wind can be the clock.

Chopsticks are used by billions of people around the world, and they have an ancient past. The Chinese have been using them for at least 3,000 years.
Early chopsticks were mainly used for cooking and were able to reach deep into boiling pots of water or oil.
As food was ready to be eaten in one bite, knives became less popular. Confucius believed that knives at the dinner table would remind eaters of the slaughterhouse (屠宰场). He also thought that knives’ sharp point will kill the happiness during the meal.
Whenever and wherever Chinese people are, they find it difficult to have a meal without chopstick. In addition, chopstick can be presented as a gift for people to express their feelings.

【推荐2】Different weather makes people feel different. Weather influences health, intelligence（智力）and feelings.
In August, it is very hot and wet in the southern part of the United States. People there have heart trouble and other kinds of health problems during this month. In the Northeast and the Middle West, it is very hot in summer and very cold in winter. People in these states have more heart trouble when the weather changes in February or March.
The weather can also influence intelligence. For example, in a 1983 report by scientists, the IQ of a group of students was very high when a very strong wind came, but after the strong wind, their IQ was 10% lower. The wind can help people have higher intelligence. Very hot weather, on the other hand, can make it lower. Students in many schools in the United States often get worse on exams in the hot months of the year (July and August).
Weather also has a strong influence on people’s feelings. Winter may be a bad time for thin people. They usually feel cold during these months. They might feel unhappy during cold weather, too. But fat people may have a hard time in hot summer. At about 18℃, people become stronger.
Low air pressure（气压） may make people forgetful. People leave more bags on buses and in shops on low-pressure days.
Are you feeling sad, tired, or forgetful today? It may be the weather’s problem.

Giving gifts is a tradition as old as mankind itself. It has always been a part of our society.
When you give a gift to someone, it tells them that they are special to you. We give and receive gifts for many occasions (场合), like birthdays, Mother’s Day, etc. In fact, gift-giving is so necessary to our world that many countries developed interesting traditions around it. Here are some of the most interesting ones.
Japan
When giving a gift in Japan, you should be very careful. It is not good to surprise them, as they will be embarrassed if they cannot immediately return something to the gift giver. The gift is usually given in private, and it is not common to open it immediately.
South Korea
In South Korea, it’s very rude to give or receive a gift using only one hand, especially if it is the left hand. You must always use both hands. Korean New Year’s greeting cards or gifts are never with a mainly red color, as it is used for announcing funerals (宣告葬礼). Also, don’t give gifts that come in sets of four as they stand for death there.
India
When giving a gift in India, you should always use your right hand. Using the left hand is impolite as that hand is considered unclean. If giving money in India, try to give a sum (金额) that ends with 1. Odd numbers (奇数) are seen as very lucky in India. The number 1 is especially lucky as it means a new beginning.
Russia
In Russia, you should never give someone yellow flowers as yellow is the symbol of ending a relationship or betrayal (背叛). As COVID-19 has changed our life greatly, many gift givers choose to send gifts online instead of sending gifts in person.

【推荐1】Many large cities are not so beautiful. There is a lot of rubbish in the streets. However, some of them can be useful. If people want to solve the problem, they should do it right now. They must take action to make use of rubbish. In this way, some good things will not be thrown away as waste.
When a car gets too old, it may not run any more. But the metal that the car was made of is still good. We can use it to make something else. When a bottle is empty, it will be thrown away. But bottle glass can be made into sand and used to build streets. Rubbish from food can be changed into fertilizer（肥料）. It is cheap and safe. Rubbish can also be used to make building blocks. These blocks are made with concrete（混凝土）to form special bricks. Now, more and more machines are designed for that.
Some day, people will watch films in a beautiful cinema which is built out rubbish. Besides buildings, roads, and cities may be made from rubbish. But so far, building beautiful cities out of rubbish is only a dream.

When we talk about learning, you must think of the regular (常规的) school ways. However the Internet is changing the way students learn. They can study knowledge and interests on apps. TED is one of them. With the Internet, learners are allowed to learn at home or anywhere else. You can watch about 700 talks from the world’s most famous thinkers, leaders and artists.
To successfully learn online, you can follow these steps. First of all, you should always keep in mind what you hope to finish by the end of it. Then, a study plan is needed. A good study plan includes a study calendar and a to-do list. Next, when having a class, be active to think about what the teacher says and express (加深印象) yourself. After class, remember to review (复习) what you have learned by reading your notes or making a mind map.
With the coming of 5G, the cloud classroom might not be far away. However, whatever advantages (优势) online learning has, it just gives a way of learning. It doesn’t change any of the ways. There must be many more ways of learning in the future. Nobody knows what will happen.
