Nowadays Internet is becoming more and more important in our daily life. People1it in schools, hospitals, offices, libraries and so on. Many students are 2 more and more time on computers. It will bring both good and bad results.

On the one hand, students can find useful information on the Internet, and it's good for studies. Also, they can practice foreign languages by talking to people in other countries.

On 3hand, some students lose themselves in online games. Their schoolwork become worse and worse. Besides, because they are always on the computer, they4talk to their families.  

5everything has two sides, so does the Internet. We should be careful to use it and make it helpful.

When we talk about inventors, we often think of Edison. He was born11847. He is known as a famous inventor. He has more than 2, 0002during his life. Many of his inventions are very3in our daily lives. Without doubt, he has made great contributions to the whole world. He was a great pioneer of invention all over the world. You can find lots of __4__ about him in different kinds of websites (网站).

Edison was not clever5he was young. But he was good at observing and thinking.

One day, his father found him squatting(蹲)on the grass. "What are you doing?" asked his father. Edison answered, "I am giving birth to a little chicken." He told his father that he saw a hen giving birth to a chicken6. At that time, he thought, "A hen can give birth to a chicken. What about me?" So he did the same as the7. He seemed to have a point.

One day, Edison was curious about the train. He wanted to know how the train8. Then he set a fire near his neighbor's house to see how fire worked. 9, the fire caused an accident. His father was so10that he gave his son a beating.

Edison went to school at the11of seven. But he thought the school was very boring. So he didn't listen to the teacher carefully. As a result, he did badly in his12. Three months later, he was forced to leave school. Edison's mother had to teach him at home and13all kinds of his strange questions. One day, his mother bought him a book14Natural Reader. He was very interested in the little experiments of the book. So he built a small laboratory at home and began to do experiments by 15. Later, he became such a great inventor.

We can see fans(扇子) everywhere in our life. But how much do you know about them?

China is named the kingdom of fans. It is said that fans were first used to cool the air during the Shang Dynasty. At that time, they were made of feathers, bamboo or silk. Some of them were round, while others were square.

Folding paper fans first became popular during the Song Dynasty. There were usually beautiful pictures on the fans. Some were mountains and rivers, and others were flowers and animals. Many people, including Su Dongpo, a poet of the Song Dynasty, and Tang Bohu, a scholar of the Ming Dynasty, even painted and wrote poems on fans. This made the fans into art works. Many rich and important people liked holding fans.

Today, fans are popular gifts. During the 2008 Beijing Olympic Games, folding fans were given to leaders and officials from other countries, as well as audience members. While they were using their fans to get cool air, they were also experiencing Chinese culture.

When I was a child, I really liked to play jokes on people I knew, especially on my parents and friends. One day my mother was cooking in the kitchen and my younger brother was playing near the window. I ran to my mother and said," My brother has fallen from the open window!" She was very worried about my brother and then I said, "Don't worry. I'm just joking." And my mother shouted at me," If you do it again, I'll punish you. "

One day I went swimming with my friends in the sea. I wanted to play a joke on my friends. At the beginning, I went swimming alone, and I called to my friends, "Help me!" All my friends came to help me, only to find out that I was joking. But the next time I wasn't joking. I swam in deep water and I was so careless that I was almost drowned. I tried my best to call my friends for help, but this time nobody came to save my life. Finally, they took me to the emergency center. From then on, I haven't joked on anyone. I think this is the best lesson in my life.

Yuan Longping, a great scientist, is the first person to develop a kind of hybrid rice(杂交水稻), which helps fight hunger in China.

Food was a big problem in China in the past. This was because China had 22 percent of the world's population, but only 7 percent of its farmland. In the 1960s, China suffered serious hunger. Millions of people died because they only had no food. As an agronomy (农学) teacher, Yuan was very sad to see this." How can I help them have enough food?" he thought. He decided to work on a kind of hybrid (杂交) rice. It has a high output (产量).

At that time, other scientists didn't think hybrid nice was worth studying. But Yuan and his team worked on it every day. They took very good care of their rice seeds. At last, in 1973，they grew a new kind of hybrid rice. This rice is strong. Farmers can grow it in many different kinds of farmland and also in bad weather. It can also fight disease. Its output was much greater than common kinds of rice. With the new kind, about 70, 000, 000 people could have food every year.

Yuan solved the food problem in China. But he is still working on rice. Before he retires, he hopes to grow rice in the sea!

Many Chinese people will wonder what presents to get for their moms on Mother's Day, but not many know Mother's Day is actually a festival from overseas.

Mother's Day originated(起源）in America during the early 20th century. The festival spread to China as early as the 1980s and was widely accepted.

Why did a foreign festival become popular in China? In fact, Chinese traditional culture has always encouraged filial(孝顺的) devotion to parents. There are many stories which show filial respect in ancient China. For example, the story of "Taste Liquid(液体的）Medicine for Mother" tells us the filial virtue(美德）of Emperor Wen of the Western Han Dynasty. His mother had been sick for three years. He often stayed up by her bedside and cared for her day and night. He tasted the liquid medicine first before she drank it. Also, mother love is a repeated subject in Chinese ancient poems, like "Song of the Parting Son" by Meng Jiao, a poet of the Tang Dynasty. Now this poem is still a must in the school textbooks. Children in China are brought up with the education of filial devotion.

On special days, people often use roses or forget-me-nots to express love. Carnations are considered as the perfect flowers for mothers around the world, but few know that China has its own for mothers—the tiger lily.

Love for mothers can have different ways of expression. What matters most is love, not the festival itself. What mothers truly want is perhaps just a simple expression of love from their children.

B: Yes, it was really fun!

A: What   you like best?

B: I agree! But I guess it was a little too crowded. 

A: I don't know…I kind of like to have more people around. It makes things more exciting.

B: That's true. Oh, and I really liked  zongzi.   

A: Oh, me too! The sweet ones are my favorite.

B: I wonder  they'll have the races again next year.   

In the face of the epidemic(疫情), many parents are about how to protect their children. What can parents do totheir children from the novel coronavirus (新型冠状病毒) at a special time?

⒈What are the possible ways forto be infected (感染)?

The National Health Commission said that children are easy to be infected by the novel coronavirus. The main route is droplet transmission (飞沫传播) coughs and contact with the mouth, nose or hand.

⒉ Can children still eat chicken, duck and fish meat?

They can eat chicken, duck and fish meat, but make sure it is. Also, don't chew (咀嚼) food with your mouth and then feed your child. Don't blow air through your mouth to cool food.

⒊ When do children need to go to hospital?

If children have coughs and other symptoms (症状), parents should first watch children's temperature. If the body temperature isn't falling and children have breathing difficulties, it's better to take children to thehospital.

⒋ How do children wear face masks?

The little children usually shouldn't wear masks. The N95 mask has the worst air permeability (渗透性) and is not good for babies. When children wear masks, parents should always pay attention tochildren have breathing difficulties or other discomfort (不舒服).

⒌ How to wash children's hands?

At all times, use the soap and running water to wash hands. If they are going out and can't wash their hands with running water right away, parents should always take paper towels.

⒍How to protect children from the virus whenout?

Staying at home is the best protection. If you must go out, wear a face mask and try not to use public transportation. If it's a short trip, walking is the best.

Alice is a college student and in her internship(实习期)now. Last month, she bought a scarf which she really liked. It cost her more than 50 dollars. It's not cheap, but it made her happy, because she had dreamed of having one for a long time.

Every morning, when she puts on her new scarf, she feels so happy that it seems the whole day is full of hope. Alice has been used to rewarding(奖励)herself through shopping. This hobby also drives her to work hard and makes her life keep getting better.

But her mother, Mrs. Miller thinks quite differently. When Mrs. Miller knew the price of Alice's new scarf, they started to argue with each other and the argument (争执) lasted for almost a whole day. Her mother thought that she shouldn't spend so much money on it, while Alice thought her mother didn't understand her at all.

But Alice didn't know that her mother's life was very hard. When Mrs. Miller was very young, she could not find enough clothes to wear in winter. She needed to learn how to spend every penny(便士, 货币单位)as if it were two so that she could survive(生存).

It's just natural that two people can't understand each other because they have different experiences. Then, how can we change the situation? Try to be patient with the people around you. Try to get to know them. And try to stand in their shoes. If Alice follows the advice, I think she will get on well with her mother.
