    After a long day's study at school, you are very tired. So after school you go home to relax. When you get home, a robot greets you. He's happy to see you and helps you take your school things to your room. He listens to you talk about your school life and tells you a new joke. And he tells you to call your cousin and to say happy birthday. And then he helps you with your homework.

    This is your future, and the robot's name is NAO. NAO has a small body, big eyes and a large head. He can walk and dance. He listens and talks, and he even learns and thinks for himself. His creators(创造者) predict that the robot will be in people's homes before 2040.

    This $16,000 robot knows who you are. NAO can even express emotions(表达情感). He is a self-guided robot. A self-guided robot can sense(感觉), think and act. Other robots might do two out of the three. For example, a robot might sense things using cameras and think using computers, but with no arms, he can't act. Another robot can move and sense things, but he can't think for himself. These aren't self-guided robots. But NAO can do them all.

    The earliest maps were probably drawn in the Middle East. Some of these maps have1and they show us the people at that time thought the earth flat(平的).As time went by, the pictures became more detailed and maps were more2made. Later on, ancient Greeks(希腊人)used their3of math and science to make maps. Greek maps tell us the Greeks knew the world was 4.

    From simple pictures, mapmaking has turned into a science. Maps are made5 surveying(勘测)land. In the1900s, people around the world started to share information to make6maps. With the help of the photographs taken from the sky and space, maps are now more exactly made than ever.7the world is always changing, we will always need new maps.

    There are many types of maps, but almost all use8and pictures to describe what a place is like when the map is made. A map usually tells what the pictures 9. Some maps may show the whole world. A road map will help you know the10from one place to another. Other maps may use pictures to show the temperature and population in different places.

    English playwright Arthur Wing Pinero said,"Where there's tea, there's hope." Similarly, a Chinese saying goesthat "Firewood, rice, cooking oil, salt, sauce, vinegar and tea are theseven necessities to begin a day."

    Tea is, without doubt, welcomed all overthe world. According to Statista, a German website for statistics (数据), global tea production reached about 5.8million tons in 2018. It has become the most consumed beverage (饮品) in the world – after water, of course.

    According to the UN, tea is much more thanjust a hot drink. It's a big part of many cultures around the world. Youprobably know that people in China use top-grade tea to show respect whenreceiving important guests. Meanwhile, the British tradition of afternoon teais an important part of that country's identity. Making Malaysia's pulled teahas become a sort of art form, where drinkers take pride in its entertainmentaspects.

    Apart from its cultural significance (意义), tea is also a medicine, used from ancienttimes to modern day. "Tea is cold and lowers the fire," Chinese MingDynasty herbalist Li Shizhen once said. The health benefits of tea are stillbeing discovered today: preventing heart disease, obesity and cancer have allbeen linked to drinking green tea, according to the National Center forBiotechnology Information in the US.

    Hot or cold, bagged or loose-leaf,teais more than a drink– it's a social custom and also a magic medicine, alink to the past and a way of life.

With a history of more than 1，800 years,dumplings are a traditional Chinese food. They are also a must for Chinese New Year. They are popular in China,especially in north China. Even some foreigners are interested in1 them. 

Chinese dumplings2 be made to look like ancient Chinese gold or silver ingots (银锭). It's said that the more dumplings you eat3 Chinese New Year, 4 money you can make in the coming year. 

People usually put minced meat (绞碎的肉) and vegetables in thin round dough skins (面皮) to make dumplings. Popular fillings are minced pork,fish,chicken,beef,and vegetables. People cook5 in different ways. 

Some people believe 6 people shouldn't eat sauerkraut (酸泡菜) dumplings during Chinese New Year. Because it means7 poor and difficult future. People like8 Chinese cabbage dumplings because it means one9 a lot of fortunes in the future. 

When making dumplings,there should10 a good number of pleats (褶) so that they will bring wealth. Sometimes a coin is put in dumplings,and the one who eats it is supposed to become wealthy. 

If a person wants to be a gentleman, he should pay attention to what he does and says. Then what are the rules for a gentleman on words and actions? {#blank#}1{#/blank#}. 

Confucius said:" If a gentleman, not caring for food or housing, is diligent（勤勉）with what he does, careful with what he says and rectifies（纠正）himself with a worthy, he can be regarded as a good learner. "

In the West, people pay too much attention to being eloquent（能言善辩的）. {#blank#}2{#/blank#}. However, Confucius didn't think so. He believed that gentlemen are supposed to choose their words carefully, even if that may make people feel bored. 

Confucius had such beliefs because he thought that words are important and that they should follow after etiquette（规矩）. {#blank#}3{#/blank#}. He said that gentlemen should not be lazy and need to focus on their work to improve themselves. 

These rules for gentlemen's words and actions have influenced Chinese people for a long time. {#blank#}4{#/blank#}. 

Of course, as culture has developed over time, we are also supposed to view（看待）his words critically（批判性地）{#blank#}5{#/blank#}.
