astronaut，reportedly，has touched the hearts of millions with a letter to her two children that was made public after she set off into space for the second time earlier this month."You're my strongest armor（盔甲）and softest spot.I didn't allow you to see me off at the launch site because I was afraid that I would burst into tears，"Liu wrote in the letter to her daughter，8，and son，6，just days before being launched into space for the second time on June 5 on the Shenz-hou.XIV mission.Liu，43，became China's first female astronaut in 2012，when she spent 13 days in space during the Shenzhou I X mission.During the Shenzhou XIV mission，she will stay at the Tiangong space station for six months，working with two male colleagues to complete the construction of the station.Many people said that Liu's words allowed them to see that a national hero is also an ordinary mother，and they wished for her safe return."Liu fully expressed her love for her children in the letter.It brought tears to my eyes，"com-mented one netizen on Sina Weibo，China's Twitter-like micro-blogging platform."I feel more confident and relaxed，"Liu told the media ahead of the launch of the Shenzhou XIV.mission."When I was about to return to the orbital module during the Shenzhou IX mission，I stopped.and turned around to salute（致敬）the experimental space station module that I stayed in.At that moment，I told myself that I would come backto space in the near future.I didn't expect the'near future' to be a decade long，"Liu said，.In the letter，she encouraged her children not to be afraid of failure while pursuing their dreams.Liu added thatshe felt sorry that she could not be there for her son on his first day at primary school."Although I cannot be with you，I won't love you any less，"she wrote in the letter."My babies，if you miss me；just look up into the starry sky.Every time you see the stars twinkle，it's because I'm saying'I love you'."（1）What is the common reason for Liu's and netizen's tears？A.Liu's affection for her children.B.Liu's indifferent expressions.C.Liu's separation from her family.D.Liu's refusal to meet with her kids.（2）Which of the following best describes Liu taking over the Shenzhou XIV mission？A.Considerate and excited.B.Talkative and expectant.C.Ready and honest.D.Confident and equipped.（3）What is Liu's purpose of writing this letter？A.To encourage kids to try.B.To say goodbye to her children.C.To catch public attention.D.To praise the spirit of space.（4）From which is the text probably taken？A.A science magazine.B.A woman autobiography.C.A Chinese textbook..D.A news coverage.3．Earthquakes have rocked the planet for many years.Studying the quakes of the past could help scientists better understand modern earthquakes，but tools to do such work are exiguous.Enter zircons.Researchers used this special means to home in on the temperatures within a fault （地壳断层）during earthquakes millions of years ago.The method offers insights into the strength of long-ago quakes，and can improve the understanding of how today's earthquakes release energy，the researchers reported in the April Geochemistry，Geophysics，Geosystems."The more we understand about the past；the more we can understand what might happen in the future，"said Emma Armstrong，a professor specializing in earthquakes at Utah State University in Logan.Armstrong and his colleagues focused on California's Punchbowl Fault.That now-quiet portion of the larger San Andreas Fault was probably active between 1 million to 10 million years ago，Armstrong said.Heat from friction（摩擦）is generated in a fault when it slips and touches off an earthquake.Prévious analyses of preserved organic material suggested that temperatures within the：Punchbowl Fault peaked between 465℃and 1065℃.The researchers suspected that air cons in rocks from the fault could narrow that broad window.Zircons often contain the radioactive chemical elements uranium（U）and thorium（Th），which decay（衰变）to helium（He）at a predictable rate.That helium （He）then builds up in the crystals：But when a zircon is heated past a temperature criticality value —the size of which depends on the zircon's composition—the accumulated helium（He）escapes.Measuring the amounts of the three elements in zircons from the fault suggests that the most in-tense earthquake generated temperatures lower than 800℃.That roughly halves the range previously reported.The finding provides useful clues to the amount of heat released by quakes，something difficult to measure for modern earthquakes because they often occur at great depths.Armstrong plans to continue studying zircons，in the hope of finding more ways to take advantage of them for details about ancient quakes.（1）What does the underlined word"exiguous"in Paragraph 1 mean？A.Scarce.B.Difficult.C.Pricey.D.Extraordinary.（2）What are the researchers' assumptions about the zircons in rocks？A.They can lead to various earthquakes.B.They determine how much of their energy.C.They can reduce the fault temperature range.D.They would decay over long periods.（3）What might Emma Armstrong study next？A.Impact of changing earthquakes on zircons.B.Origin and development of enter zircons.C.Difference between modern and ancient quakes.D.More ways to use zircons for ancient quake study.（4）Which of the following can be the best title for the text？A.Earthquakes Bring about Global Warming.B.Ancient Zircons Help to Unearth Earthquakes.C.An Innovative Means Makes a Hit in Studying.D.Zircons Changed Our Views of Earthquakes.4．Covid-19 vaccines（疫苗）began saving lives in clinical trials.But a new study，based in part on The Economist's estimate of the pandemic's true death toll（伤亡人数），attempts to model just how many lives have been spared since vaccines became widely available to the public.The study—published on June 23rd in Lancet Infectious Diseases —found that in the first .year of vaccines that were invented and introduced to the public，jobs（注射疫苗）saved the lives of peo-ple between 19.1 million and 20.4 million.Without vaccines，the study estimates，roughly three times as many people would have died from Covid-19 in 2021 alone.And 6.8 million-7.7 millon of the prevented deaths were in countries covered by .COVAX （Covid-19 Vaccines Global Access），an initiative created to ensure vaccines were sent to poorer countries.Still，a lack of vaccines in some parts of the world still led to avoidable deaths.Around 100 countries failed to reach the World Health Organization's（WHO）goal of vaccinating 40%of their qualified populations by the end of 2021.The researchers estimate that this cost around 600，000 lives.To arrive at these estimates，the researchers，Oliver J.Watson，Gregory Barnsley and their col-leagues at Imperial College London，began with an existing transmission model used to track the spread of Covid-19 infections.They then combined this model with The Economist's estimate of the pandemic's true death toll to estimate how deadly the pandemic would have been without vaccines.As for the study，every coin has two sides.It relies on assumptions about the share of estimated infectionș that led to death，for instance.Some small countries，which have limited reliable data，were not included in the analysis.That means the total number of actual avoided deaths will be even higher.On the other hand，the researchers did not attempt to model how people or governments might have changed their behavior to limit infections in the absence of vaccines.For all that，it is the most definitive answer yet to how many people owe their lives to the jobs.（1）Why are the vaccines significant according to Paragraph 2？A.They can slow down the pain of the patients.B.They can reduce the number of death toll.C.They can promote the development of drugs.D.They can realize the WHO's achievement.（2）How do the researchers at Imperial College London draw the estimates？A.By developing the transmission model.B.By comparing data between model and study.C.By combining with the previous study.D.By tracking the spread of infections.（3）What is Paragraph 4 mainly about？A.The limitations of the study.B.The assumptions of the study.C.The -results-of-the-study.D.The advantages of the study.（4）What's the author's opinion about the current situation of vaccines？A.Uncertain.B.Pessimistic.C.Cautious.D.Confident.第二节（共1小题；每小题2.5分，满分12.5分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。
