Do you like to have any online classes? It is becoming 1 to take classes at home during the early 2020. All you need is a computer or a cellphone. However, most students don't seem to like online classes. A 2 shows that only 33% of over 1,500 students from 10 cities would take such classes.

Many students said it was difficult to focus(集中) on 3 while taking online classes. Lian Ruohan, 15, at the Affiliated High school of Peking University, said, "There are no real classmates sitting near me; no real teachers watching me. I can easily surf the Internet or do 4 things if I want to. It's harder to be always focused."

In order to avoid that, Lian will prepare a lot before classes to make sure she will learn 5 in class. She also pushes herself to communicate(沟通) with teachers about difficulties. She often 6 or answers questions while taking online classes.

Wen Jiayi, 14, at the Yucai Middle School, thinks online interaction(互动) isn't 7. "I have few chances to communicate with the online teachers, and they don't really get to know me. When I don't hand in homework, all I get is only a short telephone 8 instead of real care," she said.

However, Lian thinks online classes still have many 9. "It saves time and money compared to(和……相比较) taking official classes. Also, if I can't 10 some part of a lesson, I can watch it again to make it clear."

    Good study habits are important for all students. When you have good study habits, you will learn faster and find you have a good memory.

    Do you usually study in the living room？This is not a good place for study because it's really too noisy. You need to study in a quiet place, such as your bedroom. A quiet place will help you learn better.

    Before you begin to study, do not forget to clean your desk. It helps you study well, too. Light is important, too. You will feel tired easily if there is not enough light.

    Of all the good study habits you can develop, asking questions is the key. Just ask. No one knows everything, but we can always learn from each other by asking questions.

    When do you work best？Are you an early bird, a night owl (猫头鹰), or something in between ?Find your most productive work time, and then plan to study at this time.

People in Firenze are talking happily about the new shopping mall. The new shopping mall is just outside the city, next to the city's train station. And over 70 stores are open in the mall.

People like going shopping there because there are two big supermarkets.There are also many clothes stores for them. There's a bookshop, and there are two glasses stores. There are two toy stores, and there are seven restaurants.There's even a large cinema.

Almost everyone in Firenze is excited because the new shopping mall is now open. But some people are unhappy. Do you know who they are? They are the owners(店主) of the stores in the center of the city. Many people aren't shopping in their stores but at the new mall.

A. Choose the best answers.
B. Answer the questions.

 Alice is a 6- year- old girl. She likes drawing(画画) very much and she draws every day.

 One day, after the rain(雨), she goes out(出去) with her father and her dog Coco." Wow, what's that?" she asks.

" It's a rainbow. How many colors can you see, my dear?" asks her father.

" Er… one, two, three… seven. Seven colors. It looks so nice."

 Then they go home."I want to draw a rainbow, Dad, but I don't have orange , green or purple," Alice says to her father.

" That's easy. You know what? We have the three colors. Let me help you. Mix(混合) red and yellow, and we can get orange. Mix yellow and blue, and we can get green. Blue and red can make purple."

" Wow, that's interesting! I have seven colors now. I can draw a rainbow. Thanks, Dad!" Alice draws a great rainbow. She is so happy!

 "BANG!" the door was shut loudly. I was just standing there, with my father standing on one side, and I on the other side. We were both in great anger. "Never set foot in this house again!" my father said angrily. With tears in my eyes, I rushed out and ran along the street. The street lights were shining. I felt sad and walked aimlessly (漫无目的地) . 

I didn't know whether it was because I had grown up or because my dad was getting old. He always put his opinions on me. We were just like two people in two different worlds. It felt like there was an iron door between us that could never be opened. 

My heart was frozen (冰冷的) on this hot summer night.As I walked on, there were fewer and fewer people on the streets. When I finally reached my house, I saw that the light was still on. 

"Perhaps my dad is throwing away some of his old stamps," I thought. "Perhaps he thinks they are useless." I never had the courage to tell him that I liked collecting stamps. All the lights were off except my father's. 

Dad was always like this. Maybe he didn't know how to express himself. After shouting at me, he never showed any moments of regret (懊悔) . This was how he always was. He had been a leader for so long that telling everyone else what to do had become his second nature. 

The light was still on. With the key in hand, I opened the door nervously. When I opened the door, tears ran down my face. I suddenly realized that the iron door that I had imagined between us did not exist (存在) at all. Love- it's second to none.
