To control the spread of covid-19 (新冠病毒), the Chinese government has closed schools for months. But "study must not stop", says the government. Under its orders, the country's biggest online learning begins.

There are different ways to make the online learning go on smoothly. The online teaching and learning are achieved by using video-meeting apps such as Dingtalk by Alibaba, an online company, and Ke-tang by Tencent, another online company. " ▲ " says Yue Qiu, a teacher in Beijing.

A month before my first marathon, one of my ankles (踝關(guān)節(jié)) was injured and this meant not running for two weeks, leaving me only two weeks to train. Yet, I decided to go ahead.

I remember back to my 7th year in school. In my first P. E. class, the teacher required us to run and hit a softball. I didn't do either well. He later told me that I was "not athletic".

The idea that I was "not athletic" stuck with me for years. When I started running in my 30s, I realized running was a battle against myself. It was all about the battle against my own body and mind. It was a test of wills.

The night before my marathon, I dreamt that I couldn't even find the finish line. I woke up sweating (出汗) and nervous, but ready to prove something to myself.

The next day, the Marathon started.

At mile 3, I passed a sign: "GO FOR IT, RUNNERS!"

By mile 17, I became out of breath and the once injured ankle hurt badly.

By mile 21, I was quite hungry. As I approached mile 23, I could see my wife waving a sign. She is my biggest fan.

I was one of the final runners to finish. But I finished. And I got a medal. In fact, I got the same medal as the guy who came in first place had.

Determined to be myself, move forward, free of shame and worldly labels (世俗標(biāo)簽). I can now call myself a "marathon winner".

1.A month before the marathon, the author ____________.

A.was well trained B.felt excited C.made up his mind to run D.lost hope

A.To show the support of his teacher. B.To tell the readers a funny story.

C.To show he was not talented in sports. D.To share a valuable memory.

3.How was the author's first marathon?

A.He made it. B.He stopped halfway.

C.He got the first prize. D.He walked to the end.

4.What does the story mainly tell us?

A.A man ones his success to his family support.

B.A winner is one with a great effort of will.

C.Failure is the mother of success.
