A 36-year-old man is attempting to set a new record by rowing 5,000 miles solo from Hawaii to Australia while dedicating his journey to saving the planet.

Tez Steinberg, of Boulder, Colorado, plans to leave Hawaii on December 20 on his solo trip across the Pacific Ocean. Actually, it’s the second leg of an adventure that began in 2020 when he rowed solo for 71 days from Monterey, California, to Oahu, Hawaii.

Steinberg began to experience depression while he was in college. At the time, he found a solution by participating in endurance sports. “It helped me feel better,” he said. “But as I went farther and farther, pushing myself through marathons and triathlons, I discovered this belief in myself that I’m so much stronger than I thought I was.”

However, in 2016, his life took a big turn after the sudden death of his dad. The blow caused him to challenge himself even more by solo rowing across an ocean. After successfully completing the task without any prior professional experience, Steinberg realized he could use his story to inspire other people to believe in themselves and their potential to change and grow.

Recalling the first journey at sea, he said, “I was so surprised by how beautiful the ocean was, and also how much plastic I saw. So it was that realization at sea that led me to want to go back out again.” Inspired by his first expedition, Steinberg’s new mission is to focus on ocean conservation, and specifically ocean plastics. “All the plastic I saw at sea was just heartbreaking,” he said.

The upcoming voyage will be part of an attempt to break a Guinness World Record. Nevertheless, breaking records isn’t his priority. “Personally, although a world record is exciting, that’s not why I’m in it. The world record is fun for media attention, but through it we can get more donations, support and action for ocean plastics,” Steinberg said.

1. What can we learn about Steinberg from paragraphs 3 and 4?
A.He suffered academically.
B.He was expert in extreme sports.
C.He gained confidence from motivating others.
D.He turned to challenging tasks in face of difficulties.
2. Why did Steinberg go on the first adventure at sea?
A.To recover from the state of depression.
B.To relieve the pain of his father’s passing.
C.To inspire other people to fulfil their dreams.
D.To challenge himself to achieve the impossible.
3. What is Steinberg’s main purpose in setting off for the second expedition?
A.To break a world record.B.To establish a good reputation.
C.To contribute to ocean protection.D.To urge governments to take action.
4. Which of the following best describes Steinberg?
A.Stubborn and ambitious.B.Self-centered and sympathetic.
C.Determined and knowledgeable.D.Responsible and courageous.

文章大意:本文是一篇说明文,主要讲的是世界著名的海洋生物学家西尔维娅·厄尔为了拯救海洋所做出的一些努力。

【推荐1】“What if we treat the ocean as if our lives depend on it? Or, what if we don’t?” World-famous marine biologist Sylvia Earle poses her famous “what if” questions to inspire people to reflect on how they can help save the ocean. In 1998, Time magazine named Earle its first “Hero for the Planet.”

Earle’s move to Florida’s west coast at age 12 is what started a lifelong passion. She says, “That’s where I first fell in love with the ocean.” In 1953, using newly developed equipment, the young scientist became one of the first in her field to scuba dive (水肺潜水). Her first long-term exposure to the ocean depths came in 1970 when she led an all-female research team to study the ocean. They lived under the sea in a submersible (潜水器) for two weeks. When they returned to the surface, world-wide cheer and praise were waiting, especially for Dr. Earle.

Sylvia Earle’s career includes many firsts. In 1979 she became the first woman to walk the ocean floor 381 meters below the surface. In 1990, she became the first female chief scientist of the U.S. National Oceanic and Atmospheric Administration (NOAA).

Through the years, Earle has spent roughly 7,500 hours underwater. During that time, she has become increasingly alarmed by the significant changes she has observed.

The famous scientist fears that the ocean is dying. Climate change, overfishing, the dumping of trash and chemicals and oil spills are just some of the many causes. In order to tackle the problem, Earle formed Mission Blue in 2009. This organization promotes the legal protection and conservation of the world’s oceans. Her plan is to develop “Hope Spots,” protected areas large enough to reverse (逆转) damage and restore the ocean.

1. Why does Sylvia Earle put forward “what if” questions?
A.To call on people to protect the ocean.
B.To stress our dependence on the ocean.
C.To criticize people’s damage to the ocean.
D.To contribute an article to Time magazine.
2. What can we learn about Sylvia Earle?
A.She moved to Florida to learn diving.
B.She was the best in scuba diving.
C.She did not get much attention in 1970.
D.She became a chief scientist of NOAA in 1990.
3. What is the last paragraph mainly about?
A.Scientists’ fears.B.Causes of the damage.
C.Efforts Earle made.D.Bright future for the ocean.
4. Which of the following is a suitable title for the text?
A.Dr. Sylvia Earle — A Lover of Diving
B.Dr. Sylvia Earle — Pioneer of the Deep
C.The Ocean — A place in Urgent Need of Our Care
D.Scuba Diving — A Fantastic Way to Learn the Ocean

文章大意:本文是一篇说明文,主要介绍了一种对聚苯乙烯有食欲的蠕虫可能是大规模塑料回收的关键。

【推荐2】A recent report revealed that, in the US alone, 27 million tons of plastic ended up in landfills in 2018, but only 3.1 millon tons were recycled. Wordwide the numbers are similarly bad, with just 9% of plastic being recycled. The statistics are even worse for certain types of plastic. For example, out of 80,000 tons of polystyrene (聚苯乙烯) containers generated in the United States, only a small amount (less than 5,000 tons) was recycled.

Now, researchers at The University of Queensland and have found a species of wom with an appetite for polystyrene could be the key to plastic recycling on a mass scale. The superworm can eat through polystyrene, thanks to a bacterial enzyme (酶) in their gut. To study how superworms react to purely plastic food, researchers broke up l35 of the creatures into three teams: one was fed only wheat bran(麸皮), another was fed only plastics, and the third was given nothing.

“We found the bran-fed worms have been significantly healthier than the plastic-fed or starved worms, more than doubling their weight over the three weeks they have been monitored. Though the plastic-fed worms made less impressive gains, they still put on more weight than the starved worms,” Dr. Rinke said. “This suggests the worms can get energy from plastics, most likely with the help of their gut microbes.”

Researchers used a technique called me a genomics to find several encoded enzymes with the ability to degrade polystyrene. The long-term goal is to engineer enzymes to degrade plastic waste in recycling plants.

“Super worms are like mini recycling plants, eating the polystyrene and then feeding it to the bacteria in their gut” Dr. Rinke said. It’s hoped this bio-up cycling will promote plastic waste recycling and reduce landfills. Researchers said they aim to grow the gut bacteria in the lab and further test its ability to degrade polystyrene. Then they can look into how to upscale this process to a level required for an entire recycling plant

1. What problem do the statistics in paragraph 1 indicate?
A.Landfills are poorly managed.
B.It takes a long time for plastic waste to break up.
C.Many plastic containers are of poor quality.
D.Plastics are recycle data very low rate.
2. How do researchers conduct the study on super worms?
A.By collecting data.B.By introducing a concept.
C.By making a comparison.D.By refering to a previous study.
3. What does the underlined word “degrade” in the fourth pargraph most probably mean?
A.consumeB.breakdownC.throwawayD.regulate
4. What do researchers plan to do?
A.Conduct experiments on other worm species.
B.Improve gut bacteria’s ability to degrade plastics.
C.Apply the bio-up cycling technology to recycling plants.
D.Raise super worms on a mass scale to solve plastic pollution.

文章大意:本文是一篇说明文。文章介绍了一些可以保护环境的行动。

【推荐3】Are we aware in protecting the environment?     1     Let’s take a review of how important environment is and how to protect it.

    2    

There are many organisations, at a local, national and international level devoted to the environmental protection. Together they form the Green Movement.

Whenever a habitat is threatened (威胁) by industry or development, the Green Movement takes the side of the environment. These groups already enjoy considerable public support.     3     Unless people understand how threats to the environment affect them, they cannot see the importance of environmental protection.

Encourage organic (有机的) farming.

Farming without chemicals is known as organic farming. In several countries, organic produce has become very popular. Because no chemicals are used to grow the food, there are none to enter the human food chain.     4    

Save the rainforest.

In developing countries, action is finally being taken to save the rainforests. In Africa, the Ivory Coast recently banned all timber exports. In Central America, the government of Panama made it illegal to cut down any tree more than five years old.     5     As everybody knows, timber exports have been a major source of income for them.

It is difficult to persuade poor people in developing countries of the importance of saving the forests. They need more food and want to use the land to grow crops on. What matters is not just our enjoyment of nature, but the future of life on Earth.

A.But their most important work is education.
B.Is there anything we can do about it?
C.Why are people determined to take actions?
D.Join the Green Movement.
E.Such actions show great determination.
F.Found organisations to protect our environment.
G.In addition, people think it will save the environment.
