(1) Read the following passage, use your head and think positively (13)

Burying a leaf and stubbornly believing that it will grow into a towering tree is the best dream of childhood.

In the autumn when I was 4 years old, yellow leaves fell from the tall branches. When I was playing in the yard, I leaned down and felt beautiful. I suddenly had a strange idea: will this leaf, which was once separated from Uncle Shu, grow into the same big tree after it is planted in the soil?

So I picked up many leaves, knelt on the ground and dug a small pit, and buried all the leaves in the soil. Just like my mother gave birth to me, I will grow up slowly. I firmly believe that my dream can come true.

I squatted in the place where I planted leaves every day, waiting for my big tree until it snowed heavily. I think the leaves are afraid of the cold, so they dare not come out. They will grow better next spring! I still stubbornly adhere to my dream until the swallow holds the mud and the willow shoots. ...

When I grew up, I realized that I had woven a beautiful fairy tale for myself with childlike innocence. Those leaves buried in the soil have grown into a big tree in my heart and become the pillar of my life, helping me grow up in more and more ups and downs and propping up a blue sky. ) that one thing, I am proud of it all my life. ...

Plant a leaf and you will have a towering tree.

(2) Read the article "Coke Teacher in Our Class", carefully understand and ponder (12 points).

If you ask who is the English teacher in our class, you will get the answer: "Coke." Don't be surprised, this is the homonym of the teacher's English name "kohlor", and it is also our evaluation of him. He is really coke.

His "coke" deeds are endless.

He will "steal" snacks in the small office, and after being caught by his classmates, he will also grab a handful of chocolate to "bribe" his classmates; He will lounge back in his chair and listen to his classmates' endorsements. His casual appearance made the students feel glad, but he was ruthlessly pointed out because of a small omission. He will be helpless because of the computer "losing his temper" and ask for help from everyone in a pleading tone: "Who can help me?" He will show us a stack of KFC coupons and promise us that whoever gets 100 will take him to KFC; He will talk to us, from Shakespeare's four tragedies to Confucius' Analects. He is good at playing tricks on people. At that time, he mysteriously wanted to show us his girlfriend's photo. The students were very excited and stared at the projector, but what appeared was the blonde in the picture in the book. After the students learned that they had been cheated, his triumphant appearance even aroused "public anger."

"Coke" teacher's opening remarks before class are always so novel and interesting. Once, he happily told everyone: "I tell you a good news. Guess what?"

"Good news?" Everyone became active, but no one could guess what medicine he was selling in the gourd.

"In May," he said happily, "my girlfriend and I have a holiday, and we are going-"He wrote in big letters on the blackboard: "New Orleans".

"Oh-"We suddenly realized that the text we learned today was about New Orleans. His lecture is really original.

The only thing that makes us dissatisfied with coke is that we have too much homework. Whenever "Coke" teacher finishes his homework, we always protest: "Too much!" He shouted, "Stop it!" There was a sudden silence in the classroom, only to hear him say unhurriedly, "I have the final right to interpret." The students in distress situation had to obediently accept the "imperial edict".

The most time the teacher "Coke" asked us to drink Coke was after handing out the papers. At this point, the students' resentment of his homework has long been forgotten, replaced by the joy after obtaining satisfactory results. But now our homework is getting less and less every day, and the students are puzzled. He smiled: "Reform! It's no use copying too much. It is important to improve efficiency. " That kind of self-assurance makes people feel that they are free to do whatever they want is truth.

The "Coke" teacher in our class made me really understand the meaning of "approachable". It doesn't need a serious tone, but it can make students really respect him. Really, "Coke" teacher is not only coke, but also respectable!

20, "too numerous to enumerate" refers to 2.

The role of the second paragraph in the structure of the article is
