距地球1400光年,属于银河系。
【1题详解】根据材料,编号Kepler452b天体绕着一颗与太阳相似的恒星运转,是一颗行星。
与它类型相同的是木星,B对。
太阳是恒星,A错。
月球是卫星,C错。
哈雷彗星不是行星,D错。
所以选B。
【2题详解】编号为Kepler452b的天体距地球1400光年,可能属于银河系,C对。
编号Kepler452b天体绕着一颗与太阳相似的恒星运转,不属于太阳系,A、B错。

APlaces to avoid travellingIndiaThe main distinction in wealth and class may explain some of the risk of crimes in this country. But according to John Gobbels, vice president and chief operating officer for Medjet (an international emergency service), it’s medical safety that actually makes India so dangerous. He explains that the U. S. State Department gives the country Level 2 travel advisory status. (Level 1 means you should exercise normal precautions(预防措施);Level 4 is “ do not go” .) HawaiiConsidering this destination is a very hot spot for honeymooners, it might be surprising to see the Big Island of Hawaii as a dangerous place to visit. The eruption of a volcano has put Kilauea in a state of emergency, with poisonous gas, lava flows, and earthquakes all a risk. You’ll likely see special airline deals cancelled, so think twice before making this flight.AcapulcoThis beach resort town on Mexico’s Pacific coast isn’t exactly the white-sand party destination it once was. With a Level 4 travel advisory, Gobbels explains, it’s in the same category as places like Iran, Syria, and North Korea. It’s regarded as the murder capital of the country.Cairo, EgyptAccording to a recent report from the Thomson Reuters Foundation, Cairo is considered the most insecure city for women in the world. Even though the political tensions are easing in this area, according to Gobbels, sexual violence and cultural expectations make it extremely problematic, for both locals and visitors.21. According to John Gobbels, what should visitors pay special attention to in India?A. Personal belongings.B. Travel insurance.C. Cultural difference.D. Medical safety.22. Which place mentioned above is especially dangerous for a woman tourist?A. India.B. Cairo.C. Acapulco.D. Hawaii.23. What can be inferred from the text?A. Syria isn’t a risky destination where you’ll have a wonderful vacation.B. The political unrest in Cairo is responsible for its insecurity at present.C. A Level 3 travel advisory indicates you can go with normal precautions.D. The flights to Hawaii may he changeable due to the eruption of the volcano.BPerhaps there is no sport in the world more connected to sneakers than basketball. Many NBA players wear them to send important messages and showcase their personalities on court.And now, thanks to a new policy, the NBA will strengthen its status as the most stylish sports league in the world. When the 2018-2019 NBA season kicked off in October, the NBA lifted its color restrictions on players’sneakers. It is the first time in the league’s 72-year history that it has allowed shoes to be of any color a player likes, as long as no reflective (反光的) material is included.In the past, the NBA required “uniformity (一致性) of uniform”, meaning each players’shoes had to match those worn by the rest of the team. Their sneakers had to be at least 51 percent black or white, with an element of team color.This landmark rule change is part of the NBA’s collective effort to support players “statements” on and off the court. “ More and more people realize that limitation of the color of players’shoes actually constrains (限制) their personal ex pression and storytelling,”CNN News noted.Sometimes a shoe was worn in a memorable game, or the design of a shoe has meaning for the player.Before Los Angeles Lakers superstar Kobe Bryant, nicknamed “the Black Mamba”, retired, it was said that he wore a new pair of sneakers to each game and stored his used sneakers.Bryant brought the low-top style of sneaker with a Mamba print to the forefront in 2008 to symbolize the spirit of perseverance and bravery. In 2013, Bryant added nine red stitches (缝针) to the back of his shoe to represent the nine stitches from his Achilles tendon surgery. “It has become an attitude. That is my Mamba personality,” Bryant told Sports Illustrated magazine.Kyrie Irving of the Boston, Celtics wears probably the most famous signature sneakers. Inspired by his mother, who died when he was four, he has a rose on one side of his shoe to represent her. All of his sneakers are also inscribed (刻) with the words, “JBY (Just Be You)”. “Just Be You is the motto I live by every single day, because I’m happy to be an individual. It’s a beautiful thing,” Irving told UK media site GiveMeSport.There is no end to the stories about sneakers in basketball. It’s certain that they will remaina platform for players who want to use them to express their ideas and personalities.24. According to the new policy, the NBA players ________.A. may choose sneakers they like without restrictionB. should wear sneakers in their own team colorC. have to choose sneakers either in black or in whiteD. have more freedom in choosing personal sneakers25. What can we infer from Paragraph 4?A. Uniformity guarantees better results.B. The new rule leads to controversy.C. The NBA cares little about players’ statements.D. Players’ personal expression also counts.26. Which of the following is used to express family value?A. A rose.B. JBY.C. A Mamba print.D. Nine red stitches.27. What’s the best title of the passage?A. The NBA lifts color restrictions.B. Our shoes have stories.C. Bryant has a unique dress style.D. The NBA players are particular about the colors of their sneakers.CCameron is no ordinary dog, and not just because he was born on Valentine’s Day. To Maggie, a first grader at Burgundy Farm Country Day School, the dog who spends most days on campus is more like a friend. When Cameron is near, Maggie feels “really, really, happy.” she said, “I feel safe around him.” “He’ll lie down and ask me to scratch his tummy,” she added, because Cameron likes Maggie.Cameron is one of a handful of dogs at Burgundy, a K-8 private day school in Alexandria, Virginia. Dogs started showing up there when the head of school, Jeff Sindler, brought his clumsy Labrador, Luke, to the main office building where Sindler works. After Luke died, Sindler adopted Cameron and brought him to campus, too, where the dog Maggie described as “really cute” became a school favorite.“They don’t care if you’re good at basketball, or a great reader, or popular,” Sindler said. “They just want to be loved —equal opportunity,” he added. “Cameron and the other dogs on campus —always fastened with a rope and with their owner —go a long way towards improving students’ social and emotional well-being,” he said. They reduce tension and ease anxiety, and inspire happy feelings from students.“They bring out some important emotions,” he said,“and are especially helpful to children and adults who struggle in social communication.” Children often came from challenging backgrounds: many lived in poverty, or had to travel through dangerous neighborhoods to get to school, or shared a too-crowded home. When these emotionally needy children met the dogs, they relaxed and were more prepared to learn.Just as important, dogs on school grounds set a positive, welcoming tone. They help preserve the school climate that is accepting, supportive and curious. “Dogs are one way to hold on to that,” Sindler said, adding that“schools should be fun and exciting, and dogs can be a big part of that.”For Sindler, including Cameron was all part of an effort to create a safe environment where learning could flourish.28. What makes the dog Cameron really special?A. His rare category.B. His particular birthmark.C. His attractive appearance.D. His companionable nature.29. How do dogs on campus improve students’ social and emotional wellbeing?A. By playing fetch together fondly.B. By offering them comfort equally.C. By playing basketball together freely.D. By walking a long way together happily.30. What does the underlined word “that” in paragraph 5 refer to?A. A positive tone.B. The school ground.C. A welcoming attitude.D. The school atmosphere.31. What’s the purpose of the passage?A. To encourage schools to bring in more dogs.B. To explain why dogs help students with learning.C. To introduce a way to help students grow healthily.D. To explore the possibility to challenge no-dog rules.DLucy, whose skeleton (骨骼) was discovered in Ethiopia in 1974, died shortly after she fell out of a tree, according to a new study published Monday in the British journal Nature.For their research, Kappelman and Dr. Richard Ketcham used a CT scanner to create more than 35,000 “slices” of Lucy’s skeleton. Scientists named Lucy from the Beatles song “Lucy in the Sky with Diamonds”, which was played at the camp the night of her discovery.The following analysis of the slices showed sharp, clean breaks seen at the end of Lucy’s right humerus (肱骨) are similar to bone breaks seen in victims of falls.The researchers concluded that these and other breaks in her skeleton show that Lucy, who is believed to have stood about 3 feet 6 inches and weighed about 60 pounds, fell feet first and used her arms to support herself — but that the injury was too severe to have been survivable.The researchers estimate that Lucy was going about 35 miles an hour when she hit the ground after falling from a height of roughly 40 feet, according to the statement.That sounds plausible. But other scientists are doubtful. “There are countless explanations for bone breaks,” Dr. Donald C. Johanson, director of the Institute of Human Origins and one of the scientists who discovered Lucy, said, “The suggestion that she fell out of a tree is largely a just-so story and therefore unprovable.” Johanson said it was more likely that Lucy’s breaks occurred long after she died, saying that elephant bones appear to have the same kind of breaks. It’s unlikely that they fell out of a tree.But the new research focused on “a small number of breaks” that are consistent with “high-energy bone-to-bone influences” and which differ from the sorts of breaks commonly seen in other collected bones. Kappelman responded in an email, “These app ear to have occurred at or near the time of death.”32. What can we know about Lucy from Kappelman and Dr. Richard Ketcham’s research?A. She got her name from a song.B. She had more than 35,000 slices.C. She couldn’t use her arms properly.D. She made an effort to save herself.33. What does the underlined word “plausible” in Paragraph 6 probably mean?A. Reasonable.B. Creative.C. Surprising.D. Unbelievable.34. Which of the following would Johanson probably agree?A. Elephants are likely to die from falling.B. Lucy got breaks at or near the time of death.C. Other reasons for the breaks should be considered.D. Lucy’s bone breaks differ from other bone breaks.35. What conclusion can we draw from the passage?A. Lucy didn’t die from falling out of a tree.B. The newly published study was meaningless.C. The argument on how Lucy died will continue.D. Scientists will find another way to solve the problem.第二节 (共5小题;每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。
