2 . A method to transform a commonly thrown-away plastic to a resin (树脂) used in 3D printing could allow for making better use of plastic waste. A team of Washington State University researchers developed a simple and efficient way to transform polylactic acid (PLA)(聚乳酸), a bio-based plastic used in products such as filament, plastic silverware and food packaging to a high-quality resin.

“We found a way to immediately turn this into something that’s stronger and better, and we hope that will provide people the inspiration to upcycle this stuff instead of just throw it away,” said Yu-Chung Chang, a postdoctoral researcher in the WSU School of Mechanical and Materials Engineering and a co-corresponding author on the work. “We made stronger materials just straight out of trash. We believe this could be a great opportunity.”

Although it’s bio-based, PLA, which is categorized as a number 7 plastic, doesn’t break down easily. It can float in fresh or salt water for a year without degrading (降解). It is also rarely recycled because like many plastics, when it’s melted down and re-formed, it doesn’t perform as well as the original version and becomes less valuable.

“It’s biodegradable and compostable, but once you look into it, it turns out that it can take up to 100 years for it to rot away in a landfill,” Chang said. “In reality, it still creates a lot of pollution. We want to make sure that when we do start producing PLA on the milliontons scale, we will know how to deal with it.”

While the researchers focused on PLA for the study, they hope to apply the work to poly-ethylene terephthalate (PET) (涤纶树脂), which is more common than PLA and has a similar chemical structure and presents a bigger waste problem. They have filed a temporary patent and are working to further optimize (优化) the process. The researchers are also looking into other applications for the upcycling method.

A．Solve financial crisis.	B．Change waste into wealth.
C．Control plastic production.	D．Determine 3D printing skills.

2. What does Yu-Chung Chang think of the method?

4 . There are many ways to travel within a city. We can walk, cycle, or take a bus. But no matter which way we travel, we have to follow the route (线路) the city planners laid down for us.

Parkour practitioners (跑酷爱好者), however, see the city in a completely different way. To them, there are no designed routes. There are no walls and no stairs — they jump, climb, roll and crawl to move across, through, over and under anything that they find in their path. The city is their playground.

The International Gymnastics Federation (FIG) has noticed that this activity is drawing more and more people to it — there are 100, 000 people taking part in parkour today in the UK alone, according to The Guardian — and how it is helpful for people to be much stronger: It trains coordination and balance. So the FIG is thinking about recognizing parkour as a new sport and adding it to the Olympics by 2024.

But parkour practitioners themselves don’t seem to be happy with the idea. They see parkour as “a lifestyle”, wrote the website NextSportStar. “It’s a competition against the conditions rather than just a sport.”

Indeed, many do parkour just to “escape the daily routine and experience the city in different ways”, wrote reporter Oli Mould on The Conversation. They see parkour as a way to express themselves through relaxing moves and creative routes while freeing themselves from the pressure.

It’s great that the FIG wants to develop a new sport and stay close to a new cultural form. But it would be greater if they knew that not everything in life is a competition.

1. How do the parkour practitioners do parkour?

A．They plan the way themselves.

B．They move on as they wish.

C．They run faster than others.

D．They follow certain routes.

2. Why does the FIG want to add parkour to the Olympics?

A．It’s a special way of life.

B．It draws their attention.

C．It helps balance people’s life.

D．It’s good for people to keep healthy.

3. What is the author’s idea on parkour?

A．It is more exciting than other sports.

B．It is worth adding to the sporting event.

C．It is more a lifestyle than a competition.

D．It encourages people to challenge themselves.

4. What is the best title for the passage?

A．Parkour practitioners

B．Making the city their own

C．Training in a different way

D．A new sports competition

5 . One day when I was 5, my mother scolded (责骂) me for not finishing my breakfast and I got angry. I wanted to play outside and not to be made to finish eating my breakfast. When angrily opening the screen door with my foot, I kicked back about a 12-inch part of the lower left hand corner of the new screen door. But I had no remorse, for I was happy to be playing in the backyard with my toys.

Today, I know if my child had done what I did, I would have scolded my child, and told him about how expensive this new screen door was, and I would have delivered a spanking (打屁股) for it. My parents never said a word. They left the corner of the screen door pushed out, creating an opening, a breach (裂缝) in the defense against unwanted insects.

For years, every time I saw that corner of the screen, it would constantly make me think about my mistake. For years, I knew that everyone in my family would see that hole and remember who did it. For years, every time I saw a fly buzzing (嗡嗡) in the kitchen, I would wonder if it came in through the hole that I had created with my angry foot. I would wonder if my family members were thinking the same thing, silently blaming me every time a flying insect entered our home, making life more terrible for us all. My parents taught me a valuable lesson, one that a spanking or stern (严厉的) words perhaps could not deliver. Their silent punishment for what I had done delivered a hundred stern messages to me. Above all, it has helped me become a more patient person and not burst out so easily.

1. When the author damaged the door, his parents ________.

A．gave him a spanking

7 . Tricks to Make Friends at a New School

Starting with a new school can be difficult. Everything seems to be difficult, and you don’t even know where to go for your own classes. Making new friends can be hard, too.     1    

Be yourself.

Never change who you are to try to fit in. If some people don’t accept you, they’re not the kind of friends you need.     2     For example, someone who does a lot of sports may make friends with those who also run or swim a lot.

Be friendly to others.

    3     If you think that you will say something that may make them feel sad, do not say anything and just nod your head if they talk to you. Also, remember to be as helpful as possible!

    4    

When you walk in the halls, don’t keep your eyes on the floor. Raise your head and make eye contact with other people. If you see someone you know, smile or say “Hi”. Introduce yourself. Tell them your name and where you’re from.

Remember people’s names.

You like it when people use your name, and so do other people.     5     Besides, ask them in a kind way if they have a nickname (昵称). You’d be surprised at how often this might come in handy.

A．Believe in yourself.

B．Join in after-school activities you like.

C．People often stay together because they have similar interests.

D．Remember to be nice to the people you meet at your new school.

E．These tricks can help you quickly turn some strangers into friends.

F．People may become angry if you just begin by saying “Hey” each time.

G．Don’t sit at the back of the classroom where other people don’t notice you!

8 . 阅读下面材料，根据其内容和所给段落的开头语续写两段话，使之构成一个完整的故事。

Christmas Day was coming. I was just a kid then, and my big sister told me there was no Santa Claus. I fled to my Grandma because she would be straight with me. I knew Grandma always told me the truth. Grandma was home, and I told her everything. “No Santa Claus?” She shouted. “Ridiculous! Don’t believe it. “Now, put on your coat, and let’s go.”

“Go where, Grandma?” I asked. “Where” turned out to be Kerby’s General Store, the one store in town that had a little bit of just about everything. As we walked through its doors, Grandma handed me ten dollars. “Take this money, and buy something for someone who needs it. I’ll wait for you in the car.” Then she turned and walked out of Kerby’s.

I was only eight years old. I’d often gone shopping with my mother, but never had I shopped for anything all by myself. The store seemed big and crowded, full of people competing to finish their Christmas shopping. For a few moments I just stood there, confused, holding that ten-dollar bill, wondering what to buy and who to buy it for. I suddenly thought of Bobby Decker, who was a kid with bad breath and messy hair. He sat right behind me in Mrs. Pollock’s grade-two class. Bobby Decker didn’t have a coat. I knew that because he never went out for break during the winter. His mother always wrote a note, telling the teacher that he had a cough, but we kids knew that Bobby Decker didn’t have a cough, and he didn’t have a coat. I would buy Bobby Decker a coat! I chose a red one, which looked really warm, and he would like that.

“Is this a Christmas present for someone?” the lady behind the counter asked kindly, as I laid ten dollars down. “Yes.”

The nice lady smiled at me, put the coat in a bag and wished me a Merry Christmas.

注意：1.续写词数应为150左右；
