Beijing Aerospace Control Center in Beijing，Jan.3,2019.It touched down on the far side of the moon at 1026 am.Beijing Time，becoming the first spacecraft soft-landing on the moons unknown side never visible from Earth.Chinas Change-4 probe has started the exploration on the far side of the moon thanks to the relay satellite that provides a communication link with ground control.The relay satellite，named Queqiao，meaning Magpie Bridge，after a Chinese legend(传说)，was launched on May 21,2018，and became the first communication satellite operating in the halo orbit，nearly 500,000 km from the earth.It can also provide communication for probes from other countries.The relay satellite will also be used for scientific and technological experiments.The maximum distance between the satellite and the Change-4 probe on the far side of the moon is 79,000 km.The satellite processes data from the probe and sends it to Earth.The satellite can stay in its orbit for a long time due to its relatively low fuel consumption，as the earths and moons gravity balances its orbital moving.While in orbit，it can“see” both the earth and the far side of the moon.The concept of using a relay satellite in the halo orbit was first put forward by US.space experts in the 1960s，but was realized by Chinese space engineers.Researchers hope to use the cameras on the satellite to record asteroids (小行星) hitting the far side of the moon.To control the cost of the Change-4 probe，the relay satellite was designed to be relatively small，weighing about 400 kg.Researchers had just 30 months to develop the satellite，putting them under high pressure.To promote public interest in space exploration，the China National Space Administration invited people to write down their wishes for lunar and space exploration，and the relay satellite carries the names of tens of thousands of participants and their messages.28What do we learn from the second paragraph?AThe relay satellite was launched on Jan.3,2019.BChange-4 probe was the first communication satellite.CThe relay satellite only explores the far side of the moon.DThe relay satellite can handle data from Change-4 probe.29Why was the size of the relay satellite relatively small?ATo reduce the cost as much as possible.BTo make it circle Moon for a longer time.CTo avoid being crashed by other satellites.DTo follow American space experts advice.30What made researchers suffer from great stress?AFew people interested in the exploration on the moon.BThe relay satellite carrying too much equipment.CTheir lacking enough time to develop the relay satellite.DPeoples never being optimistic about the relay satellite.答案C31What is the main idea of the text?AChina is a new space power after the USA.BChange-4 probe lands on Moons far side.CChinese space engineers make much progress.DSpace exploration is a dangerous challenge.答案DACBD(2020·全国)Race walking shares many fitness benefits with running，research shows，while most likely contributing to fewer injuries.It does，however，have its own problem.Race walkers are conditioned athletes.The longest track and field event at the Summer Olympics is the 50-kilometer race walk，which is about five miles longer than the marathon.But the sports rules require that a race walkers knees stay straight through most of the leg swing and one foot remain in contact(接触) with the ground at all times.Its this strange form that makes race walking such an attractive activity，however，says Jaclyn Norberg，an assistant professor of exercise science at Salem State University in Salem，Mass.Like running，race walking is physically demanding，she says.According to most calculations，race walkers moving at a pace of six miles per hour would burn about 800 calories(卡路里) per hour，which is approximately twice as many as they would burn walking，although fewer than running，which would probably burn about 1,000 or more calories per hour.However，race walking does not pound the body as much as running does，Dr.Norberg says.According to her research，runners hit the ground with as much as four times their body weight per step，while race walkers，who do not leave the ground，create only about 1.4 times their body weight with each step.As a result，she says，some of the injuries associated with running，such as runners knee，are uncommon among race walkers.But the sports strange form does place considerable stress on the ankles and hips，so people with a history of such injuries might want to be cautious in adopting the sport.In fact，anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper technique，she says.It takes some practice.32Why are race walkers conditioned athletes?AThey must run long distances.BThey are qualified for the marathon.CThey have to follow special rules.DThey are good at swinging their legs.33What advantage does race walking have over running?AIts more popular at the Olympics.BIts less challenging physically.CIts more effective in body building.DIts less likely to cause knee injuries.34What is Dr.Norbergs suggestion for someone trying race walking?AGetting experts opinions.BHaving a medical checkup.CHiring an experienced coach.DDoing regular exercises.35Which word best describes the authors attitude to race walking?ASkeptical. BObjective.CTolerant. DConservative.答案CDAB第二节(共5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。选项中有两项为多余选项。Some individuals are born with a gift for public speaking. 36 Do you want to be a good public speaker？Here are some principles you must master.People want to listen to someone who is interesting，relaxed and comfortable.Too often，when you stand up to give a speech，you focus on the “public” at the expense of the “speaking.” 37 Focus on the speaking.Talk directly to your audience，be yourself and make a connection.Even the most successful public speaker will make mistakes.Yet，the only one who cares about any mistake is the one who is speaking.Peoples attention wanders constantly.In fact，most people only absorb about 20 percent of a speakers message.So，dont stop speaking when you make a mistake unless its a truly serious one. 38 Your goal is not to be a perfect public speaker. 39 And like everything else in life，that takes practice.Remember，even world champion athletes practice their skills on a consistent basis. 40 Its rare to hear someone say，“I wish that speaker had spoken longer.” On the other hand，you probably cant count the times that youve thought，“Im glad that talk is over.It seemed to go on forever！” So surprise your audience.Always make your presentation just a bit shorter than anticipated.Its better to leave your listeners wishing for more than shifting restlessly in their seats waiting for your speech finally to end.ADo the opposite.BYou want to be an effective public speaker.CYou dont need to apologize for a minor slip.DWhen it comes to public speaking，less is usually more.EThe objective of most speeches is to benefit the audience.FTake the fear out of public speaking by focusing on your listeners.GHowever，the majority of people are effective speakers because they train to be.36G37A38C39B40D第三部分语言运用(共两节，满分30分)第一节(共15小题；每小题1分，满分15分)阅读下面短文，从每题所给的A、B、C、D四个选项中选出可以填入空白处的最佳选项。My friends and I had just finished lunch at a hotel when it started to pour 41 .When it became lighter，I decided to get my car，which was 42 at my office three streets away.My friends argued that I shouldnt go，mainly because I was seven months pregnant then.I assured them that Id be very 43 .I walked out of the 44 and started making my way to the car.At the traffic junction，a van stopped and a passenger got off with an umbrella.Before I knew what was happening，he walked right beside me and told me hed escort(护送) me to my 45 .I was very embarrassed and declined(辞谢)，but he was very 46 .During our 47 ，he kept telling me to walk slower，as the ground was 48 .When we got to the car park，I 49 him and we parted ways.I did not get his 50 and may not even recognise him now.Did he 51 stop for me？Ill never know.So how did I pay it forward？I was at home when I 52 two Indian construction workers walking in the heavy rain.They were probably on their way to the construction 53 near my estate，which was a long walk in.I went out and passed them an umbrella.I told them they should take the umbrella and 54 it.They were very grateful and like me，probably wondered why a 55 was offering such kindness.41A.hardly BslightlyCheavily Dslowly42A.parked BlockedCbroken Drepaired43A.successful BcarefulCjoyful Dstressful44A.storm BgarageCoffice Dhotel45A.destination BhomeCoffice Dcompany46A.cautious BdiligentCpersistent Dreluctant47A.talk BtripCwalk Dwork48A.rough BwetCmessy Ddirty49A.thanked BleftCwaved Dgreeted50A.umbrella BappearanceCaddress Dname51A.obviously BaccidentallyCreally Dpurposely52A.watched BnoticedCsearched Dheard53A.equipment BstageCobject Dsite54A.keep BcarryChave Dreturn55A.passer-by BstrangerCman Dwoman41-55 CABDA CCBAD DBDAB第二节(共10小题；每小题1.5分，满分15分)阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。The way we cook is important.In many countries，the two choices are 56.
