Today, paper-making is a big business. But it is still possible to make paper by hand, since the steps are the same as using big machines.

You should use paper with small amounts of printing. Old envelopes are good for this reason. Colored paper also can be used, as well as small amounts of newspaper. Small pieces of rags or cloth can be added. These should be cut into pieces about five centimeters by five centimeters.

Everything is placed in a container, covered with water and brought to a boil. It is mixed for about two hours with some common chemicals and then allowed to cool. Then it is left until most of the water dries up. The substance left, called pulp(紙漿), can be stored until you are ready to make paper.

When you are ready, the pulp is mixed with water again. Then the pulp is poured into a mold. The mold is made of small squares of wire that hold the shape and thickness of the paper. To help dry the paper, the mold lets the water flow through the small wire squares.

After several more drying steps, the paper is carefully lifted back from the mold. It is now strong enough to be touched.

The paper is smoothed and pressed to remove trapped air. You can use a common electric iron used for pressing clothes.

1.It is suggested that we “should choose paper with small amounts of printing” to_____.

A. make paper by ourselves

B. renew the old envelopes

C. make various colored paper

D. create our own newspaper

2.Whether the paper is strong enough to be touched is determined by _____.

A. how long the pulp is stored

B. how thick the paper is

C. how much water remains

D. what type of chemicals are used

3.When the paper is lifted from the mold, it is time to _____.

A. make it smooth B. make it strong

C. decorate it D. use an iron

4.The passage is most probably intended to _____.

A. introduce the history of paper-making

B. describe the process of paper-making

C. compare the ancient with the modern paper-making

D. argue about the possibility of paper-making by hand

Dear Alcohol,

You’ve been around forever. I can remember all the pain you’ve caused for me.

Do you remember the night you almost took my father’s life? I do. He loves you. Sometimes I think he loves you more than he loves me. He’s addicted to you, to the way you promise to rid him of his problems only to cause more of them. You just sat back and laughed as his car went spinning through the street, crashing into two other cars. He wasn’t the only one hurt by you that night.

Do you remember the night of my first high school party? You were there. My friends were intrigued by you. They treated you as if they were never going to see you again, drinking all of you that they could. I spent two hours that night helping my friends who had fallen completely. “I’m so embarrassed,” they said as I held their hair back so that they could vomit (嘔吐). “I’m sorry,” they said when I called taxies for them, walking them out and paying the driver in advance. “This won’t happen again,” they said as they were sent to the hospital to have their stomachs pumped. Two 15-year-old girls slept in hospital beds that night thanks to you.

Do you remember the night when you took advantage of my 17-year-old neighbor who had to drive to pick up his sister from her dance lessons? Do you know how we all felt when he hit another car and killed the two people in the other car? He died the next morning too. His sister walked home from her dance lesson, and passed police cars and a crowd of people gathering on the sidewalk just two blocks away from the dance studio. She didn’t realize her brother was in the midst of it all. She never saw him again. And it’s all your fault.

I wish you’d walk out of my life forever. I don’t want anything to do with you. Look at all the pain you’ve caused. Sure, you’ve made people happy too from time to time. But the damage you’ve caused in the lives of millions is inexcusable. Stop luring（誘惑）in the people I love. Stop hurting me, please.

Sincerely,

Anonymous
