"When I was 16 years old, I was diving in Greece, but I was disappointed because I saw more plastic bags than fish.” These are the words of Boyan Slat, an engineer who designed the world's first ocean plastic cleanup system.
Every year, more than 8 million tons of plastics end up in our oceans, according to the UN Environment Programme. It is predicted that the weight of ocean plastics will match the weight of all the fish in our oceans by 2050. To prevent this from happening, in 2013 Slat created the Ocean Cleanup, an environmental non¬governmental organization, and put his plan for an ocean cleanup device into action.
After years of research and develop¬ment in the Netherlands, a device called System 001/B successfully started gathering plastics on October 2, 2019. The device uses a 600-meter-long C-shaped tube to gather all the floating rubbish. Unlike other cleanup methods, the system floats freely according to the direction of the waves, which allows waste to flow into and stay within the device. A sea anchor is attached to either end. This slows down the system as it floats through the water and allows the faster-moving rubbish, carried by the waves, to flow into its mouth. System 001/B can also collect waste below the surface using a 3-meter-deep skirt（挡板）attached to the end. After being gathered, the trash will be dragged back to shore by boat and recycled.
Right now, the system operates in the Great Pacific Garbage Patch, an area that is 3 times the size of France. Once operational, the Ocean Cleanup expects a full fleet to be able to clear 50% of the Great Pacific Garbage Patch in 5 years.
"It remains to be seen whether this dream will become a reality, but it is undeniable that humanity must work together to reduce our plastic use and repair the damage our waste has caused," Slat said. "We are starting to see a young generation that gets it and is excited about a sustainable （可持续的）future, but the question still comes down to: Are we going fast enough, and how much damage will have been done before we get there?"

B.It can only gather ocean waste which floats on the water.
C.It aims to clear up the Great Pacific Garbage Patch in five years.

Last weekend in Washington, D.C. 30 young researchers from across the nation were preparing for a competition. In a sense, all were winners already. After all, each had to beat out hundreds of others for the chance to arrive in the final. But only one competitor would take home the top prize: an educational award worth $25,000. Finally, Alaina Gassler, 14, won the top prize.
Alaina was one of the 30 finalists from 13 states who competed in the ninth yearly Broadcom MASTERS competition. Alaina and the other finalists had to be in sixth, seventh or eighth grade to attend the competition. What’s more, their research had to be judged within the top 10 percent of all projects. As usual, those projects all fell within the fields of science, technology, engineering or mathematics. Fifteen of the finalists took home major awards. For the first time this year, 60g% of the finalists were women.
Alaina developed a system whose goal is to improve driving safety. “Congratulations to Alaina, whose project has the possibility of reducing the number of traffic accidents,” said Maya Ajmera, president of Science and the Public, the organization that created the competition.
Alaina goes to school in West Grove, Pennsylvania. “I didn’t think I’d win an award this big.” she said. For her project, Alaina developed a system that could reduce blind spots for drivers. Such areas can hide objects or other cars from a driver’s view, and thus easily lead to accidents.
Alaina’s system depends on a camera fixed on the front part of the passenger-side window. It can monitor (监视) things a driver can’t see. The camera records a video of what it’s seeing and at the same time sends it to a projector (投影仪) fixed over the driver’s head. That projector plays the video on a screen, which is fixed on the passenger-side roof support. In this way, the blind spots are decreased.
1.What do we know about the competition?
A.It encourages teamwork. B.It is meant for college students.
C.It encourages theory exploration. D.It is a fierce national competition.
2.What is special about this year’s competition?
A.More winners stand out. B.More girls perform better.
C.All of the projects are more useful. D.Half of the competitors are awarded.
3.How does Alaina Gassler feel about her prize?
A.Surprised. B.Satisfied. C.Encouraged. D.Puzzled.
4.What plays the biggest role in Alaina Gassler’s system?
A.The projector. B.The monitor. C.The camera. D.The screen.
While waiting to pick up a friend at the airport in Portland, Oregon, I had one of those life-changing experiences. One man stopped right next to me to greet his family.
First the man walked up to his oldest son. He cupped his face in his hands and said, “You’re already quite a young man. I love you very much, Zach!”
Then he went to his youngest son. They gave each other a long, loving hug. Then I heard the father say, “It’s so good to see you, son. I missed you so much!” With his eyes turning away and his face becoming redder, his son replied softly, “Me, too, Dad!”
While this was happening, a baby girl was moving excitedly in her mother’s arms. The man said, “Hi, baby girl!” And then he gently took the child from her mother. He quickly kissed her face all over.
After several moments, he handed his daughter to his oldest son and said, “I’ve saved the best for the last!” He walked forward to give his wife the longest, most passionate kiss I ever remember seeing.
It seemed that they just got married, but I knew by the age of their kids that they had been married for long. I pondered it for a moment and couldn’t help asking. “Wow! How long have you two been married?”
“Been together fourteen years in total, and been married twelve of those.” he replied. “Well then, how long have you been separated?” I asked. The man smiled, “Two whole days!”
Two days? I was shocked. Judging from the greeting. I had thought they’d been separated for at least several months. I said almost immediately, “I hope my marriage is still that passionate after twelve years!”
The man suddenly stopped smiling. He said something that left me a different person. He told me, “Don’t hope, friend…decide!” Then he gave me his wonderful smile again. They left together happily.
1.How did the youngest son respond when his father said he missed him so much?
A.He seemed deeply touched. B.He looked extremely proud.
C.He was very excited. D.He got slightly shy.
2.What does the underlined word “pondered” in Paragraph 6 mean?

3.What made the author shocked?
A.That the father greeted each family member differently.
B.That the wife hadn’t seen her husband for just two days.
C.That the couple had been together for long.
D.That the father answered his question.
4.What can be the best title for the text?
A.A Father’s Deep Love for His Children B.My First Impression of an Old Couple
C.A Life-changing Experience at the Airport D.My Experience of Picking up a Friend

I live in a typical Chinese family of four generations lived together under same roof. Everyone has funs with each other here. Every night, we will have dinner together, talking or laughing around the dinner table so that all the worries of the day will be swept away. At weekends, Dad will take Grandpa, that likes outdoor activities a lot, to the countryside to fish. Mom and Grandma will cook delicious food for ourselves. When the weather is fine, I will push my 95-year-old great grandmother in a wheelchair to sunbathe in the yard. My family is such harmonious that I have been grown up into a person with love and responsibility. I will definite teach what I had already learned to my future children.
