On Thursday, singer and actress Selena Gomez, 25, used Instagram to explain why she was “laying low” this summer. She posted a photo of herself in a hospital bed with her friend Francia Raisa holding hands. She said she recently received a kidney transplant from her best friend because of complications(并发症) from lupus(狼疮), an autoimmune disease, which means it is the result of the immune system attacking normal tissue, including the kidneys, brain, heart and lungs.People with lupus may first experience tiredness, joint pain or a little bit of rash(皮疹) on their bodies and can go for a long time before their doctors realize it is more serious. Many people see two or four doctors before the real problem is picked up. According to Dr. Kyriakos Kirou, roughly a third to one-half of people with lupus develop kidney disease, and up to one in five of them will eventually need a transplant, sometimes because theyweren’t treated with effective drugs to prevent the immune system from attacking the kidneys. Though Gomez said that she was “very well now,” she warn ed about the dangers of not taking medical diagnoses seriously, like she initially did.Her Instagram post also called attention to two major health topics: the need for living organ donators and the fact that Gomez represents three groups more likely to be diagnosed with lupus and lupus-related kidney disease. Nine out of 10 people diagnosed with lupus are women, and most develop the disease between the ages of 15 to 44. And lupus is two to three times more common among women of color, including Hispanic women, according to the Lupus Foundation.Raisa is Latina, and Gomez’s father is of Mexican origin. While it’s not essential that the organ donator and receiver be of the same ethnicity, people who share a similar background sometimes are better matched, according to data from the United Network for Organ Sharing.24. What can we learn about Francia Raisa?A. She is lucky.B. She is selfless.C. She is optimistic.D. She is encouraging.25. What is lupus like at its early stage?A. It is deadly.B. It is hard to recognize.C. Its symptoms are psychological.D. It reminds you of a kidney disease.26. What does the underlined word “them” in Paragraph 2 refer to?A. People with lupus.B. Colored women lupus patients.C. Lupus patients with kidney disease.D. Women between the ages of 15 to 44.27. What does the last paragraph mainly tell us?A. Raisa and Gomez have a similar background.B. Gomez has fully recovered thanks to the kidney from Raisa.C. It is vital for the donator and receiver to be of the same race.D. The organ from the donator of the same race matches the receiver better.C（云南民族大学附中2018届高三下第一次月考）The world’s richest man might seem to have it all, but Bill Gates has one regret. The self-made billionaire said he felt stupid for not knowing any foreign languages.Speaking in his third Ask Me Anything question-and-answer session for online forum Reddit(红迪网), the Microsoft founder said that he wished he spoke French, Arabic or Chinese.He said: “I took Latin and Greek in high school and got A’s and I guess it helps my vocabulary. I keep hoping to get time to study one of these—probably French because it is the easiest. I did Duolingo for a while but didn’t keep it up.”Gates, who is worth $79.3 billion, praised Facebook founder Mark Zuckerberg for surprising an audience in Beijing when he spoke fluent Chinese. “Mark Zuckerberg amazingly learned Chinese and did a Q&A with Chinese students—unbelievable, isn’t it?” he saidThis isn’t the first time for Gates to admit his regret over language. He also sh owed his habits at home and personal insights.Last February, Gates said he likes to do the dishes himself—to his own special standards every night and also told the interviewer that his wife, Melinda, would likely want Samuel L. Jackson to play her husband in a biopic(传记片).He also admitted that he would pick up a $100 bill if he found it on the street.As he took the top spot on Forbes(福布斯)28th Annual Billionaires list last year for the fourth time, he said he is pretty basic when it comes to spending on clothes and food, but that he enjoys investing in shoes andracquets(球拍)when he plays tennis.When asked a life lesson he had to learn the hard way, the billionaire said staying up too late is a habit he is still trying to break. “Don’t stay up too late eve n if the book is really exciting. You will regret it in the morning. Pam still working on this problem.” he said.28. Which of the following can be the best title for the passage?A. An Interview with Bill GatesB.

However, their ability to recognize human faces from photos alone is novel.The recent study, the results of which were published in the journal Royal Society; Open Science, show the woolly creatures could be trained to recognize still images of human faces, including those of former President Barack Obama and actress Emma Watson.Initially, the sheep were trained to approach certain images by being given food rewards. Later, they were able to recognize the images for which they had been rewarded. The sheep could even recognize images of faces shown at an angle, though their ability to do so declined by about 15 percent—the same rate at which a human’s ability to perform the same task declines,“Anyone who has spent time working with sheep will know that they are intelligent and individual animals who are able to recognize their handlers.” said Professor Jenny Morton, who led the Cambridge study. “We’ve shown with our study that sheep have advanced face-recognition abilities, close to those of humans and monkeys.”Recognizing faces is one of he most important social skills for human beings, and some disorders of the brain, including Huntington’s disease, affect this ability.“Sheep are long-lived and have brains that are similar in size and complexity to those of some monkeys. That means they can be useful models to help us understand disorders of the brain, such as Huntington’s disease that develop over a long time and affect cognitive (认识的) abilities. Our study gives us another way to monitor how these abilities change.” Morton said.32. According to the new research, what’s unusual about sheep?A. They have large brains.B. They can recognize their owners.C. They can tell animals from humans.D. They can recognize human faces from photographs.33. How did the researchers train the sheep?A. By giving food rewards.B. By showing photos of famous people.C. By guiding them to follow their handlers.D. By showing photos of humans and monkeys by turns.34. What can be inferred from the passage?A. Sheep have a higher face-recognition ability than monkeys.B. The new discovery is of great benefit to the study of cognitive ability changes.C. The sheep’s face-recognition ability may prevent some disorders of the brain.D. The sheep’s face-recognition ability stays the same when shown photos at any angle.35. What’s the best title of the passage?A. A Wonderful ScientistB. The Life of SheepC. A New Discovery about SheepD.
