A Chinese sturgeon(中华鲟) was freed into the Yangtze River in Yichang, central China’s Hubei Province on Saturday morning in March. China will free 200,000 Chinese sturgeons into the Yangtze River, the country’s     1     (long) river, as part of its efforts     2     (protect) the rare fish. According to China Three Gorges Corporation, they     3     (conduct) the release(释放)every year since 1984.

With     4     history of 140 million years, Chinese sturgeons are among the most ancient vertebrate species on earth and are under Class-A protection in China. The fish are     5     (large) protected through artificial breeding(人工繁殖), followed by release into natural environment.

Sturgeons released this year are between 6 months and 14 years old, a design aimed     6     helping the restoration of the wild population. Before the release, larger sturgeons were attached with trackers for knowing about environmental impacts on the species’     7     (survive) in the wild, in order to inform future protection     8     (measure).

In recent years, China has worked hard in ecological protection along the Yangtze River, with a 10-year fishing ban (禁令)     9     (carry) out in key waters along the river at the beginning of 2021. Actually, China passed the Yangtze River Protection Law in December 2020,     10     provided legal support for biodiversity protection in the river.

Ever wonder    1    it would feel like to hide away in a dark cave without being connected to the outside world for 40 days? Fifteen people in France just did that. The group    2    (live) in a cave as part of the Deep Time project. The project was conducted by scientists from the Human Adaptation Institute, who wanted to see how they would react to and cope with being    3    (total) disconnected from the modern world. Since the volunteers    4    (cut) off from the outside world, they had to rely    5    their body clock to know when    6     (wake) up, go to sleep and eat. As expected, those in the cave lost their sense of time. “Time seemed to pass more slowly in the underground cave, where there were neither clocks    7    sunlight,” said Deep Time’s director Christian Clot.

The majority of the volunteers said they enjoyed the experience of total isolation. Two-thirds expressed a desire to remain underground a while    8    (long) in order to finish projects they had started. “The experience tested humans’ ability to adjust    9    (they) to the sudden huge changes in living conditions and environments,” said Clot. “We hope to better understand how our brains are capable of    10    (find) new solutions, whatever the situation.”

Most people drink tea in the world. But tea does not mean    1    same thing to different people. In different countries, people have different ideas about    2    (drink) tea.

In China, for example, tea    3    (serve) usually when people get together. Chinese people drink it    4    home or in tea houses anytime of the day. They often use hot water to boil tea    5    (leaf).

Tea is also important in other    6    (Asia) countries. People in these countries have a special way of serving tea. They hold a tea ceremony in their houses when important guests come. It is very old and full of meaning. Everything must be done in a special way in the ceremony. There is even a special room for it in their houses.

In the United States, people usually drink tea at breakfast    7    they drink it after meals. Americans usually use tea bags    8    (make) tea. This way is faster and    9    (easy) than the way of making tea in teapots. In summer, most Americans drink    10    (ice)tea. They like to put some ice in their tea.

A famous painting of Marilyn Monroe created by American artist Andy Warhol was sold for $195 million on Monday. That is     1     most ever paid in a public sale for a work by an American. Warhol painted Shot Sage Blue Marilyn in 1964. The     2    (color) image shows Monroe with yellow hair, blue eye shadow and bright red lips, with a rich blue background.

The sale took place at Christie’s auction (拍卖) house in New York. Many     3    (representative) from Christie’s said the painting became the costliest work of art ever     4    (sell) from the 20th century. Warhol’s painting passed the earlier record holder, Jean Michel Basquiat. His 1982 painting Untitled of a skull-like face was sold for a record $ 110.5 million in 2017 at Sotheby’s in New York. Warhol created     5    (much) than one image of Monroe. The Shot Sage Blue Marilyn painting has been shown     6     museums around the world. Christie’s said an unnamed buyer made the purchase on Monday night.

When the auction     7    (announce) earlier this year, Christie’s estimated it could go for as much as $ 200 million. “It’s an     8    (amaze) price,” said Alex Rotter, chairman of Christie’s 20th and 21st century art department. “Let it sink in. It’s quite something.”

The earnings of the sale will go to the Thomas and Doris Ammann Foundation Zurich,     9     puts the painting up for auction. The foundation aims     10    (help) children with health care and educational programs.

Nowadays, vegetarian(素食主义的)eating is becoming more popular. Although it does have a good reputation for     1    (benefit)our health, recent news has focused on what could be bad about vegetarian diets,     2    (include)stroke risk, harm to brain health, hair loss and depression.

British researchers     3    (follow)more than 48,000 men and women with no history of heart disease or stroke for about 18 years. Vegetarians had a 20%     4    (high)rate of stroke than meat eaters. Another expert wrote that the trend towards vegetarian diets may lead to a choline(胆碱)crisis, Choline is a nutrient(营养物)    5     is important for brain health and other functions. It can     6    (find)in meat, and our body can’t make all that humans need.

So, can giving up meat lead to hair loss? A recent report found that a severe lack of protein, among other diet shortcomings, can lead to it. That’s     7     meat contains iron, vitamin B, and zinc, which are all important for hair     8    (grow).

Can vegetarian and vegan diets affect our mood? Research on this is mixed. Some studies have found that going meatless     9    (improve)mood, but others have found     10     opposite. In one study of 400 new mothers, 80 of them suffered from postpartum(产后的)depression. A vegetarian diet was one factor that seemed to make it more likely to be depressed.

Our wedding was unconventional and it was exactly what Matt and I wanted. We both had failed marriages in the past, so we planned to do something different this time     1     (express) our desire that this one     2     (last); a sunrise ceremony on the Wisconsin shore of Lake Michigan. We even wrote our vows and     3     (person) information and put them in a bottle. To share our love with the world, we threw the bottle into     4     lake. “It will be     5     (high) interesting to find out where it ends up,” I told Matt.

Since we held this special ceremony, Matt and I had managed to stay together happily. But years later, I began to have a little     6     (anxious) and doubt about our marriage.

One day, Matt went to the mailbox and took out the mail. There was a letter     7     (write) to us. He carried the mail inside, sat down at the kitchen table     8     the letter and opened it. It turned out that our bottle     9     (find) by a couple,     10     were also married on the Wisconsin shore on August 18 twenty. Eight years ago. When we read it in disbelief, my negative thoughts about our marriage somehow disappeared.

War started in our house in late July with a month to go before my first day of college. There were a number of colleges for me to go to. Mom, who was an     1     (optimism) woman, wanted me to attend a famous nursing school, and       2     did Dad. But I wanted to go to a small writing college. Every night for two weeks, my mother and I argued, shouted and gave silent treatments (沉默以待) until both sides went to bed with regrets. Neither of us     3     (be) willing to agree with each other.

Since my junior year of high school, I had aimed at being a nurse. While     4     (take) all the science courses, I was also working as a volunteer in my town's local hospital. My motivation was to help the sick and be a superwoman to the world.

Yet, as graduation and college neared, it all changed. Having the sick     5     (treat) was noble, but not what I was meant to do for the rest of my life. The career was not so enjoyable.

But writing was what I had been doing as a hobby and I would concentrate     6     it. I     7     (firm) believed that it was going to be my career. I could be absorbed in it. On August 1st, no sooner had Mom and I sat down at the dinner table than I told her that she had every right to choose where to spend her money, just like I had every right to decide where I wanted to go to school.

    8     (persuade) to let me attend a small writing college in the end, my mother decided to support me, which meant the world to me. My mother said to me, "Would you like to be a writer?” I answered, "Yes, I would like to." In the end, I won my mother's real     9     (approve).

Before that time, never     10     I stood up against my parents on any major decision. I am now finished with my first term and I cannot wait to see what comes next.

Nowadays, Chinese people     1    （impress）by the progress of our country, which is extremely exciting. We     2    （make）great progress in science and technology in the past decades, especially the progress in space exploration. We conquered the space, and the conquest represents a visible proof of our nation’s     3    （strong）.

The advances in space technology will be     4    （benefit）to us in the long run. Thanks to communication satellites, we can see television pictures transmitted（传送）across the globe, and we can communicate with our friends and business partners     5     are far away from us. Without exploring the space, we could never figure out its mysteries（奥秘）or broaden our horizons far beyond the boundary of     6     planet Earth.

Besides, what distinguishes us from animals     7    （be）that we know we need to explore. Actually, the space technology is not only the search     8     knowledge but also a mirror of the development of our nation. We will become proud of our motherland, We will devote ourselves to     9    （develop）our country.

China is growing stronger and stronger, and it will never fall behind in the progress of science and technology. We are looking forward to new     10    （breakthrough）, and we believe they will come up in the near future.
