It was a fine spring day with beautiful flowers in the park. A young man arrived early and waited for his girlfriend under a big tree. But he was so short-tempered(脾气暴躁的) that he wasn't in the mood to enjoy the view.

Suddenly, an angel appeared. “Put this button(纽扣) onto your clothes. If you don't want to wait, just turn the button to the right. You can skip over any time period if you want to. "

The man happily held the button and turned it softly. Oh! How amazing! His girlfriend appeared before him and was gently smiling to him! How I wish our wedding ceremony could be held now ! He turned the button once again. A great wedding appeared in front of him, the beautiful bride was standing next to him and the band was playing cheerful music. He lost himself in it deeply.

The desires in his heart kept coming out : I also want a big house with a garden in the front. He turned the button. Then he wished for children. All of a sudden, a group of lovely children were playing happily in the huge living room. Again, he jumped at the chance to turn the button to the right.

How time flew. Before he could see beautiful flowers in the garden, everything had been covered in deep snow. Looking at himself again, he found his hair was totally white. He had already become so old.

He felt so sad. He would rather enjoy life step by step than watch it go by in such a hurry. He quickly turned the button to the left. Once again, he was waiting for his lovely girlfriend under that big tree.

My name is Tim. Daddy didn't know how to show love. He went to work every day and blamed (责备) me for the mistakes I had made when he came home.

Once I broke my leg and it was Mum who held me in her arms all the way to the hospital.

Later, Dad pulled the car right up to the door of the hospital.

They asked him to move it, saying the space was saved for the ambulance(救护车). Dad shouted, “What do you think this is? A tour bus?”

At my birthday parties, Dad always seemed out of place. He just kept himself busy blowing up balloons, setting up tables, and welcoming the guests. It was Mum who carried the cake with the candles on it for me to blow out.

When I learned to ride a bike, I asked him not to leave me alone, but he said it was time. I fell and Mum ran to pick me up, but he stopped her. I was so mad that I showed him that I could ride it myself. He just smiled.

When I went to college, Mum did all the writing. He just sent money and a little note about how great his garden looked now just because I wasn't playing football on it.

Whenever I called home, he acted like he wanted to talk but always said, “Wait, Tim. I'll get your mother.”

Every year on a special day in March , the world celebrates women's day. Women from different countries have done great achievements and made a difference. The BBC has made a list of the greatest icons of the 20th century. Among the list's 28 people, 11 are women. Let's meet three of them.

Jane Goodall ( 1934-present, UK)

Jane Goodall is one of the most famous zoologists in the world. She studied chimpanzees in a special way and made some great findings. Goodall didn't study chimpanzees in a zoo. She spent 38 years in the wild forests in Africa. She lived among them and found that chimpanzees used tools, lived in groups and had feelings like love and anger. This showed that humans and chimpanzees might have the same ancestors. Goodall's findings surprised many people. We started to ask ourselves: What does it mean to human'? How can we better protect animals?

Billie Jean King ( 1943-present, US)

In English-language news, when you read about "relations between Beijing and Washington", it actually means "relations between China and the US". That's how important capital cities are -they stand for the country. The capital city has many roles. It is home to the central government as well as a center for cultural and economic activities. However, capital cities usually have a large population, which can be a big problem.

In August, 2019, Indonesia said that it will build a new capital on the island of Borneo. One of the reasons for this is that Jakarta, the current capital, is overpopulated. In Jakarta, the traffic is heavy and the areas people live in are crowded. What's worse, the ground has been going down at an average rate of about 10 centimeters a year and in some northern parts the ground is already 2 to 4 meters below the sea level. Rising sea levels linked (关联) to climate change could make the problem even worse in the future.

Last century, Rio de Janeiro, the then capital of Brazil, was overpopulated as well. In 1960, the country moved its capital to Brasilia to solve this problem. People believed that if they moved the capital to a less-developed city, Brazil would have more balanced development. This turned out to be right.

Many capital cities are facing problems as they develop. Besides building a new one, maybe new technology can help solve some of the problems.

Beijing In 2015, China's government called for building "smart" cities and planned to turn Beijing into one of these cities. A new sub-center in the city's Tongzhou district will be the testing ground for this idea. "Smart" technology will be used to solve traffic problems, control air pollution and recycle garbage.

Tokyo The capital of Japan is working to make itself a "green" city. People are encouraged to plant trees on their rooftops. The city will use technology to recycle rainwater and turn a landfill into a forest.

Singapore Singapore is a city-state. It is using internet of things(物联网）technology to help save energy. In public housing, smart sensors (传感器) remind people of how much water and electricity they are using.

1.With the example of Brazil, the writer tries to tell us that .

A.it can be a good choice to move a country's capital

B.Indonesia can move its capital city Jakarta to Brazil

C.it is right for every country to change its capital city

D.most capital cities usually have a large population

2.What can we learn from the passage?

A.Capital city can represent all the roles of the country.

B.Water will cover the current capital of Indonesia soon.

C.Beijing has solved many problems by using technology.

D.Both Japan and Singapore are working to save energy.

3.The passage mainly talks about _______.

A.how to use new technology smartly B.how to solve the problems of capital cities

C.what the problems of capital cities are D.what the relationship between capital cities is

Dear Lucy,

I had a funny experience last year. After I had left a small village in the south of France, I drove on to the next town. On the way, a young man waved to me. 1.. As soon as he had got into the car, I said good morning to him in French and he answered in the same language. Except for a few words, 2.. Neither of us spoke during the journey. 3., when the young man suddenly said, very slowly, "Do you speak English?" As I soon learnt, he was English himself! We laughed happily and I told him I lived in London. 4., "I am a Londoner, too!"

Finally, we gave telephone numbers to each other and made an appointment(约定) that after we went back to London, we would meet again. 5., Lucy, do you think so? Next time, I will tell you more interesting stories happening in my journey all around the world.
