Two hundred audience members, including the mayor of Reno, Nevada, look to the stage. Dozens of costumed actors break out into the drama—The Lion King. This is not a typical production. The cast is made up of homeless children living at the V olunteers of America family shelter in Reno. Children have been given a chance to live their dreams onstage, thanks to volunteer acting coach Nasya Mancini.“I see so much of myself in these kids,” says Nasya. “I tell them their current circumstance doesn’t have to be their future. If they are determined they can do anything they want.” She was born prematurely, weighing 1.25 pounds, which was given little chance of survival. But Nasya kept fighting. She had open-heart operation at two weeks old. Doctors predicted she’d be in the hospital for five months. She came home in nine weeks. Her very name (pronounced “Nah-SY-ah”) means “magic” in Hebrew.Nasya quickly proved a big talent for acting. At six she was spotted by an acting coach. Nasya once told her friends, “I’m going to be an actor. One day I’m going to be a star.” Some higher graders said, “You? You’re a small fry. You’re not even pretty.” Later, one popular girl said, “I can play better than you. And if you’re not better than me, then how can you be an actor? Give. It. Up.”Later, she entered the V olunteers of America shelter center. She learned there were more than 300 people living there and many children were even mistreated and lost theirconfidence. Nasya was stunned. “I was so blessed that I didn’t realize how blessed I was!” she says. “I’m healthy, have wonderful parents, a great home. I couldn’t believe how many homeless children there were right in my own backyard.”Long after Nasya won the title of Miss Northern Counties Outstanding Teen, she has stayed committed to the kids at the V olunteers of America shelter. At each class she reminds the kids, “Believe in yourself. The world is your stage.”24.Which of the following can best describe Nasya?A.Good-mannered and brave.B.Self-centered and mature.C.Warm-hearted and talented.D.Well-educated and honest.25.What does the underlined word “stunned” in Paragraph 4 mean?A.Shocked.B.Frightened.C.Confused.D.Impressed. 26.How does Nasya help the homeless teens to build confidence?A.By encouraging them.B.By donating money to them.C.By acting in a drama.D.By turning them into big stars. 27.What does Nasya want to tell children through her story?A.Kindness matters to stars.B.Talent is crucial for acting.C.Children need a dream stage.D.Magic lies in trusting yourself.When it comes to cancer, red meat is often thought to be the bad guy. But new research from the University of Chicago has shown that a nutrient found in red meat may support our body’s ability to fight off cancer cells.The nutrient in question is called TV A, which is a long-chain fatty acid (酸) that our bodies cannot make by themselves. “TV A in humans is mainly from foods, including beef and lamb,” said study author Jing Chen, a professor of medicine at the University of Chicago. In the new study, Chen’s team collected 255 bioactive substances from nutrients into a database and tested whether any of the substances could affect the immune (免疫的) system’s ability to fight cancer cells. Specifically, the team focused on their ability to activate a class of white blood cells called CD8+ T cells, also known as killer T cells, finding and destroying infected cells and, in this case, cancers.After evaluating the top six substances in both human and mouse cells, the team found that TVA produced the best results. “TV A strengthens CD8+ T cell function and thus promotes T cell-based immune system response to battle cancerous growth,” Chen said. Theteam found that mice with a diet enriched with TV A saw significantly reduced cancerous growth. “Focusing on bioactivity of nutrients rather than individual food might be more important, and taking supplements (保健品) with enriched bioactive nutrients is likely more efficient than consuming foods containing these nutrients,” Chen said.Chen thinks there may be other nutrients that can do the same. “There is early data showing that other fatty acids from plants signal through a similar receptor as TV A, so we believe there is a high possibility that nutrients from plants can do the same thing,” he said. 28.What might be the general opinion about red meat?A.It helps fight cancer.B.It brings health risks.C.It is rich in fatty acids.D.It contains no nutrients.29.How does TV A support the immune system?A.By producing nutrients.B.By killing infected cells.C.By collecting substances.D.By activating killer T cells.30.What does Chen most probably suggest readers do?A.Go vegetarian.B.Eat less red meat.C.Prevent cancer actively.D.Take a TV A-enriched diet.31.In which section of a newspaper may this passage appear?A.Science.B.Education.C.Sports.D.Entertainment.Anger is the most destructive emotion. When you are angry, you make ill-considered decisions that you will probably regret. You will also regret language spoken without thought. Therefore, what can be done to control anger and prevent it from ruining our lives? 32 .Firstly, you need to change your attitude to the way of the world. 33 . Also, you need to accept that not everyone has the same standards as you. Many people try to live by high standards, and as a result, are often disappointed and become angry. The answer is to be a bit more flexible and relax your control of life.Secondly, don’t regard anger as a bad emotion. There are occasions when anger can be directed in such a way as to achieve great things. Martin Luther King was angry about the lack of civil rights in the USA.Gandhi was angry about British rule in India. 34 . They both used that anger to motivate themselves to fight against what they saw as injustice.Thirdly, reacting angrily is a hard habit to break. But it is a habit, and habits can be broken. The trick is to avoid reacting when faced with a situation that usually angers. Anger isa negative reaction, but in this type of situation, there is no good in reacting by forming positive thoughts. 35 . This way, your anger will not get the emotional food it needs to survive.36 . That control will come once you identify what is at the root of your anger. Make changes to your lifestyle and attitudes and you will find that you will turn angry much less often, if at all.A.By contrast, anger is slow to passB.You need to learn not to respond at allC.Anger of this type can be used to fuel actionD.Here are some ways you can fight against angerE.People do behave in ways that will make you angryF.In conclusion, you must recognize anger is something you can controlG.Realizing that no one is perfect is a good start to avoiding getting angry三、完形填空Life is a journey filled with ups and downs.

The changes of immune microenvironment play critical roles in the progression or reverse of liver fibrosis. As one component of innate immune cells,natural killer( NK) cells have anti-fibrotic effects through direct killing of HSCs by cytotoxity and secretion of anti-fibrotic cytokines such as interferon--y( IFN--y) ,as well as also cause some damage to the liver. The roles of NK cells are regulated by its receptors, other immune cell and molecules.【Key words 】 Liver fibrosis; Nature killer cells ; Hepatic stellate cells;Interferon-7;ReceptorFund program : Natural Science Foundation of Shandong Province( ZR2016HM19)DOI : 10. 3760/cma. j. issn. 16734394. 2021.02. 014用[6]。
