The Shidaowan Nuclear Power Plant, located in Rongcheng, Shandong Province, has officially begun commercial operations following     1     successful 168-hour trial, as announced by the National Energy Administration (NEA). This marks a significant milestone as it is the world's first fourth-generation (4G) nuclear power plant, utilizing high-temperature gas-cooled nuclear reactor (HTGR) technology.

The plant, which boasts China's fully independent intellectual property rights, showcases the nation's prowess in 4G nuclear power technology. According to Zhang Zuoyi, the chief designer of the project, the HTGR is designed to be inherently safe, even in the absence of cooling capabilities and without any intervention     2     (measure). This ensures    3     accidents such as reactor core meltdowns or radioactive material releases are prevented.

In comparison to other renewable energy sources like solar, wind, and hydro, nuclear power stands out for its stability and cost-effectiveness, as       4    (highlight) by Lin Boqiang, the director of the China Center for Energy Economics Research at Xiamen University. This makes it a viable option for China to achieve its carbon emission    5     (reduce) goals.

The construction of the 200,000-kilowatt plant, which     6     (start) in December 2012, was a collaborative effort between China Huaneng Group Co, Tsinghua University, and China National Nuclear Corp. It was first connected to the power grid in December 2021, marking a significant step forward in the development of nuclear power technology.

The success of the plant is attributed to the collaborative efforts of over 500 companies across the industry chain, including design, research and development, construction, component manufacturing, and operations management. With a localization rate of equipment exceeding 90%, this achievement underscores China's commitment to foster innovation and technological advancement.

Based on this project, China Huaneng Group Co and Tsinghua University have jointly developed six core technologies, nurtured a talented team of experts, and formed a reproducible operation mechanism with independent intellectual property rights. This not only demonstrates China's capabilities in nuclear power development but also     7     (pave) the way for future collaboration and innovation in the field.

As China continues its efforts to achieve carbon emission reduction goals, the installed capacity of renewable energy power generation nationwide has reached a new high. By the end of October, it had exceeded 1.4 billion kilowatts,     8     (reach) 1.404 billion kilowatts, representing a year-on-year increase of 20.8%. This significant growth accounts for    9    (approximate) 49.9% of the country's total installed capacity of power generation, further underscoring the importance of renewable energy in China's energy mix.

With the successful commercial operation of the Shidaowan Nuclear Power Plant, China has once again proven     10     (it) leadership in the global energy landscape and its commitment to sustainable development.

The Baihetan hydropower plant, China's second largest hydropower facility on the upstream branch of the Yangtze river, was     1     (formal) completed on Tuesday after the last generating unit was connected.

The plant is estimated to generate 62.44 billion kilowatt-hours annually,     2     could save about 90 million tons of coal a year and cut annual carbon dioxide emissions (排放) by about 248 million tons.

Baihetan is one of six huge hydropower     3     (station) along the Yangtze river, China's longest. The Three Gorges Corporation, the project's developer, has described the 289-meter dam (大坝) and     4     (it) associated facilities as one of the country's biggest and     5     (challenging) engineering projects.

Construction began in 2017, with a total investment     6     (estimate) at 170 billion yuan. As     7     major project in China's west-east power transmission (输送) program, it will deliver electricity across the country     8     cities in the east.

China goes on     9     (construct) hydropower plants in the southwest, despite a long and severe drought in the summer of 2022 that saw generation volumes drop, forcing regions     10     (limit) power consumption.

Marine biology is the study of the ocean’s plant and animal life. Marine life gives us food, medicine and other raw materials we need. It also supports tourism and provides us with an area of recreation.

    1     (difference)forms of life live in various areas of the ocean. Some are limited to coastal and shelf areas, while others live in the open sea.

Coral reefs     2     (find) in the tropical areas of the world, but they can also exist in colder water. Reefs are built by corals and other     3     (animal)that leave calcium on rocks. They are home to     4     vast variety of life forms. About half of the world’s coral reefs, however,are     5     danger because of global warming and a rise in sea temperatures.

Although we do not know very much about    6     kind of life forms exist in deep ocean trenches(深海沟), marine scientists have found a certain type of jellyfish(水母) in the Mariana Trench, the world’s     7     (deep)ocean area. These parts of the ocean     8     (usual)have little or no sunlight and many organisms(生物)here have to produce light     9     (they).

Marine scientists also study how waves and currents affect organisms     10     (live)in the oceans.

Documentary on poverty alleviation (扶贫) to hit cinemas

Documentary film Rooting is due to hit cinemas nationwide     1     April 20, highlighting the stories of villagers in Yunnan Province’s Shawa Village     2     presenting the village’s changes over four years.

Lately, a trailer (预告片)     3     (release), focusing on the only road in the village of Fugong County.     4     (live) deep in the mountains near the Nujiang Canyon, the     5     (village) could only communicate with the outer world by travelling via a dangerous mountain track. As China’s campaign poverty alleviation deepens,     6     proper road was finally built for the village.

“This film features realistic problems in that remote village, giving credit to the contributors behind the scene and their efforts. That’s     7     the film ends with a line: ‘This film is dedicated to all those     8     have contributed to poverty reduction in China,’” said Chai Hongfang, the film’s director.

On March 17, the film held a special screening at the 2023 International Forum on Poverty Governance and Global Development, joined by more than 190 government officials and experts from 20 countries and four international organizations aiming     9     (exchange) views on poverty governance, rural building, modernization and sustainable development.

Apart from being     10     (public) screened, the film will also be screened in more than 100 Chinese universities and countries along the Silk Road Economic Belt and 21st Century Maritime Silk Road.

Jennifer Jones, a teenage girl, passed     1     in her morning PE lesson after skipping meals and then she was rushed to hospital. She     2    (find) to have dangerously low blood sugar levels and was treated     3    (immediate). Fortunately, she is now out of danger. Her doctor says that she will make a full     4    (recover) in a day or two. “She hasn’t eaten breakfast for months,” her friend Laura Williams told the reporter. “I warned her that     5    (skip) meals was unhealthy, but she wouldn’t listen.”

Jennifer’s case is a reminder of the dangers of the     6    (healthy) weight-loss habits that have become common among teenagers of both sexes. “These so-called ‘quick-fix methods’ prove     7    (be) harmful to teenagers. It is normal for teenagers to be slightly overweight and there is no reason     8     they should be worried. However, for those who are seriously overweight,     9     is very important that they try to lose weight properly,” said an expert. “Besides, they should get much exercise     10    (stay) energetic and fit.”

Every Saturday night Mama would sit down by the kitchen table and divide the money     1     Papa had brought home into several parts. Each part had     2     different use. For example, the big silver pieces were for the rent. In our     3     (day) life, Mama tried her best not to draw money out     4     her Bank Account, however hard the life was. When Nels wanted to go on to high school, my family members and I did our best     5     (earn) or save money instead of     6     (go) to the Bank. To get enough money, Nels     7     (volunteer) to work in Dillon’s grocery after school; Papa decided     8     (give) up smoking and I planned to look after the Elvington children every Friday night.

Twenty years later, when the check of my first story came, I hurried over to Mama’s and asked her to put     9     in her Bank Account. She had to admit that she had never been inside a bank.

Actually, Mama’s Bank Account mentioned many times by Mama was just     10     (make) us children feel secure.

She was growing up, Camille Roberts always saw science in her future. Her parents are both doctors of chemistry and she wanted to follow     1     (they) example by going into research about     2     (medical).

The 24-year-old girl says her parents taught her the importance of giving others a hand, so she saw medical research as a way of     3     (help) improve society. Looking for education in such a field would     4     (probable) lead to a highly-paid job. So, in 2013, Roberts     5     (begin) studying biomedical engineering(生物医学工程) at George Washington University in Washington, D.C. During her four years there, she not only volunteered to do something     6     (use) in the city, but also worked as an assistant (助手) to several teachers, which introduced her     7     more personal ways to help people.

After completing     8     series of studies in 2017, Roberts took a research position at the National Institute of Mental Health. But she soon felt deeply unhappy. So in 2018, she was determined     9     (take) a job that she felt much more pleasant: teaching.

Many of Roberts’ former classmates and coworkers now have jobs     10     pay them much more than she makes, but Roberts says she would not trade more money for the creativity and purpose she now finds in her work.

Most people dream of living in a big expensive house. But Tim Shea just wanted to find a place     1     could become his home.

This 70-year-old homeless man had spent several years living on the streets until he became the first resident of a village filled     2     3D- printed little houses.

Shea was chosen to be the first person     3    (move) into Community First Village , a 51- acre site in Austin, Texas. The small houses in the village , like Shea’s 400-square-foot home, were built by the Austin-based start-up company ICON.

Life wasn't easy for Shea before     4     (live) in Community First Village. He lived in an RV(野营车) for most of his life. This made     5    (he) stay away from people. “ I think from my     6    (person) experience of my former lifestyle, I developed a shell,” Shea said. “ I didn't feel secure(安心的)and any time I had the opportunity，I would hide.”

Luckily,    7    (thing) changed when Shea got his new house. Since then, he has been meeting new people and making friends. “Now everything I do     8    (be) just the opposite. I have many activities to do every day with others,” Shea said.

The houses     9    (design) by ICON have six different layouts (布局). Shea chose a home with an open floor. This way,     10     will be easier for him to use his wheelchair.

Emerging evidence in humans suggests a     1     (typical) Western high-fat, high-sugar junk food diet can quickly weaken your brain's appetite control.

After offering volunteers a week-long binge (大吃大喝) of waffles, milkshakes and similarly rich foods, researchers in Australia found young and healthy ones scored worse on memory tests and experienced a     2     (great) desire to eat junk food, even when they were already full.

The findings suggest something is special in the hippocampus (海马体)-a region of the brain     3     supports memory and helps to regulate appetite. When we are full, the hippocampus is thought to quieten down our memories of delicious food, thereby     4     (reduce) our appetite. When it’s interrupted,     5     control can be seriously damaged. Over the years, extensive research on     6     (mouse) has found the function of the hippocampus is very sensitive to junk food, but recently this has been observed only in young and healthy humans.

In 2017, after a week of Western-style breakfasts of     7     (toast) sandwiches and milkshakes, researchers found participants performed worse on learning and memory tests which are typically dependent     8     the hippocampus.

Now, in this latest study the scientists of the team     9     (find) that not only do such high-fat, high-sugar diets impair memory in humans, but they appear to directly affect our ability     10     (control) our appetite.

Instruments are a necessary part of making music, but what music sounds like will also depend upon     1     (it) style and rhythm. Music is often divided     2     two main groups: classical and popular. These names can mean different things to different people, and their meanings can change over time.

Popular music is what many people play or listen to for fun. It could be folk, country, pop and rock, or jazz. Often the music style     3     (change) with each new generation of musicians. All over the world there are     4     (talent) musicians who perform this style of music     5     (earn) a living or just for fun. A band of musicians usually play a certain style of music that they like,     6     (create) a sound that is special to them.

Classical music is     7     (most) used to describe more formal music, often performed in front of a seated silent audience. Most of this music     8     (write) a long time ago. Classical music is often played by an orchestra (管弦乐队) in     9     musicians play either woodwind, brass, or string instruments.

There are many famous orchestras throughout     10     world, with many countries having their own special ones.
