Ben’s dad was pu tting pieces of wood over the windows while his mom was making sure the flashlights and radio were working. She also put some candles and matches on the table.Ben was helping his mom make dinner when the rain began to beat heavily against the windows. After dinner, they tried to play a card game, but it was hard to have fun with a serious storm happening outside.Ben could not sleep at first. He finally fell asleep when the wind was dying down at around 3:00 a.m. When he woke up, the sun was rising. He went outside with his family and found the neighborhood in a mess.

Soon the news of friendly dolphins swimming around Monkey Mia began to spread, and before long the beach became very popular. However, by the 1980s, researchers had noticed a worrying fact —as adult dolphins became more dependent on humans for food, more and more of their babies died. Things got so bad that 90% of the babies failed to grow up. Luckily, the local government started to control dolphin feeding.Today, only a small number of dolphins visit the Monkey Mia beach every day. And they are only fed a little fish so that they still go out hunting(猎食) and teach their young survival(生存) skills. Visitors can only feed the dolphins when they are allowed. “We only feed them around 10% of their daily food,” said Luke Skinner, a staff member there. “This makes them go and hunt for 90% of their food.”The dolphins that visit Monkey Mia every morning draw more than 100,000 visitors to the beach each year. Visitors can get close to the dolphins, play with them and learn about them and their habitat.36.What do we know about Monkey Mia?A.It is a zoo. B.It is a beach in Australia.C.It is named after a fisherman. D.It is a natural habitat of monkeys.37.What does the underlined word “them” in Paragraph 2 refer to (指的是) ?A.The dolphins. B.The fishermen. C.The monkeys. D.The researchers.38.What happened in the 1980s?A.Lots of adult dolphins began to die.B.Many dolphins were killed by fishermen.C.Monkey Mia became too crowded with visitors.D.More and more baby dolphins failed to grow up.39.How does the local government protect the dolphins?A.By protecting their habitat. B.By controlling dolphin feeding.C.By teaching them hunting skills. D.By cutting down the number of visitors.40.The writer wrote the passage to ________.A.introduce the best place the dolphins live inB.advise us to teach baby animals survival skillsC.show the reasons why the visitors can’t feed the dolphinsD.tell us to pay more attention to animals, survival rulesDBy Global TimesMay 12th, 2022______▲______China’s Zhurong rover (祝融号) has found evidence (证据) showing that water has been on Mars (火星) much longer than expected.Zhurong, named after the Chinese god of fire, landed safely on Mars on May 15th, 2021, making China only the second behind the United States to fully succeed.Zhurong, the Mars rover, is 1.85 meters high and weighs about 240 kilograms. It has six wheels and four solar panels (太阳能面板) and it can move at 200 meters an hour on Mars.The rover’s three-month primary mission (任务) was to search for signs of ancient life. It has done research on the minerals, environment and location of water and ice in the plain. The rover continues to research into its landing place and send information back to the Tianwen-1. The rover returned some information from its primary survey of the basin. It shows that Utopia Planitia basin had water during a time, but many scientists used to believe Mars to be dry and cold.“Mars is the planet we are most likely to live on in the future. That’s why we want to understand it,” said Ge, a scientist in China’s space program. “Zhurong’s evidence of water on Mars makes great progress in future Mars missions!”41.China becomes only the ________ to land a rover successfully on Mars according to the passage.A.first B.second C.third D.fourth42.Which picture does Zhurong rover look like?A.B.C.D.43.According to the passage, we can infer (推断) that ________.A.the news came out on May 15th, 2021 B.the rover returned three months agoC.the rover may send pictures back to the Tianwen-1 D.Mars used to be dry and cold in the ancient time 44.What does the underlined word “it” refer to (指代) in the last paragraph?A.Tianwen-1. B.Mars. C.Future. D.Zhurong.45.Which of the following titles can be put in ____▲____?A.The new findings on Mars B.The future life on MarsC.The appearance of Zhurong Rover D.The landing of Zhurong Rover四、情景交际(每题1分,共5分)46.妈妈请你倒垃圾,你可以这样答应她:________________________________.47.得知Cindy 感冒了,你可以这样建议她:Cindy, ________________________________.48.你想知道Sandy 对愚公这个故事的看法,可以这样问:Sandy, ________________________________ the story of Yu Gong?49.你想知道Mary是否已经读过《三体》,会这么问:Mary, ________________________________ The Three Body Problem yet?50.外教老师想了解厦门最高的山峰是哪座,可以这样问:________________________________ in Xiamen?五、根据情景写句子(每题1分,共5分)根据每小题所提供的图画情景和提示词,写出一个与图画情景相符的句子。
