For centuries, the “Big Four” diamonds, red stones, green stones and blue stones—ruled the gem (珠宝) world. When tanzanite first appeared in 1967, it became a hit. Unlike those other stones, which are mined all over the world, tanzanite can be found in only one place on Earth: in the remote Merelani Hills in the shadow of Mt. Kilimanjaro in Tanzania, Africa.Gem of the century meets deal of the century. With its remarkable rarity and unique gemstone qualities, it’s no wonder that experts have called it “the gemstone of the 20th century”. In recent years, top-quality tanzanite gems have fetch ed higher prices at auction (拍卖会) than the Big Four! But because we buy direct and use our own designers, we are able to offer you this rare beauty for ONL Y $59!What makes tanzanite so ir resistible to gem experts? Part of its appeal is the beautiful violet blu e color. Tanzanite is also trichroic—which means that three different colors are visible when the stone is viewed from different angles.A gemstone found in only one place on earth means supply is extremely limited. Get your hands on the Karatu Tanzanite Ring before they’re gone!Your satisfaction is 100% guaranteed. Experience the rare beauty of the Karatu Tanzanite Ring for two months. If you’re not completely impressed, simply send it back within 60 days for a complete return of the sale price. We want you to feel like you got the deal of the century!21. What is tanzanite?A. A ring brand.B. A kind of stone.C. A place in Africa.D. A deal of the century.22. What is special about tanzanite?A. Its bright color.B. Its high price.C. Its long-standing reputation.D. Its unique place of origin.23. What is the purpose of the text?A. To promote goods.B. To introduce a gem.C. To present a discovery.D. To recommend return service.BRepositioning the light for the third time, Reilly leaned (倾斜) the phone at an angle she thought would make her face look skinny. She prepared herself for her best smile in3,2, 1!Finally! A picture she can work with. Everyone else in school had a social media account and nobody knows how hard she tried to eve ntually get mom’s permi ssion. She had been sitting up her account for days, and the picture of herself was the final touch.She had worked cautiously creating her profile. Her hometown was boring, so she filled in a more exciting one several towns over. Her job was nonexistent since she was only 14, but she filled in “Accountant”. Why not? Seemed like a cool job. And she was getting good at making a perfect account here, so “accountant” was fitting.She wrote her first post. Then deleted it. She wanted to avoid sounding like she just started an account. She thought of something brilliant.“Hey new account here, had to. You know, locked out of my other one. Add me here!”Now people would think she had to start this one because an old one got hacked (非法入侵)，and they just didn’t know she had none before. Then the “friend spread” would happen. The website would start suggesting her page to friends of friends until she grew her list to a respectable size.It was starting already! Friend requests on her list. A comment! “Gorgeous (漂亮的) girl!” It was from Amy, in her science class. Reilly felt gorgeous.At school, Reilly looked around wondering who saw her new profile.“Hey. Saw your new account,” Nora, her best friend, said from somewhere behind her.“How does it look?” Reilly asked.“It looks pretty cool. But, I almost didn’t know it was you, Reilly,” Nora smiled. “And just in case you forget, you are good enough as you are.”24. What was Reilly busy doing these days?A. Looking for a cool jotB. Chatting with friends online.C. Setting up a social media account.D. Improving her photography skills.25. Why did Reilly rewrite her post?A. To sound more experienced.B. To add something brilliant.C.

Creating a profile totally on her own.D. Expanding her influence on social media.27. What does Nora’s comment imply?A. Reilly should appreciate her true self.B. Reilly should pursue the best version of herself.C. Reilly shouldn't be too proud of what she's done.D. Reilly shouldn't forget to show the good side of her.CA new network of dedicated antennas (天线) in Africa will lend insight into the damage that storms of charged particles (粒子) from the sun make on satellite and radio communications. Zambia set up its first such sensor in March —one of eight multifrequency receivers being stationed around Africa, in addition to four already operating in South Africa. Kenya and Nigeria will set up their receivers by the end of the year.The Space Weather network that extends over Africa will provide real-time data on how solar storms distort (扭曲) the ionosphere, the charged outer layer of Earth's atmosphere. This distortion can have dangerous consequences, says Mpho Tshisaphungo, a space weather researcher at the South African National Space Agency (SANSA). Signals between crucial satellites and the ground pass through this region, where charged particles can cause interference (干扰). Also, high-frequency radio signals (often used in defense and emergency services communications) have to bounce off the ionosphere; Tshisaphungo notes that when solar storms change the layer, “the radio signal may eithe r be weakened, delayed or absorbed by the iono sphere.”“While there are data available from international space weather programs, if you want to look at what’s happening on the African continent, then you need to take measurements in Africa,” says John Habarulema, a space scientist at SANSA. Habarulema’s team developed a model last year that maps electron density (电子密度) in the ionosphere and fills in measurement gaps. The new local receivers will boost this model's accuracy and let it describe fluctuations (波动) over the full continent. “We need to have the global perspective and put that data into our global models,” says Terry Onsager, a U.S. physicist. “But at the same time, space weather disturbances can vary enormously from location to location.” And it is becoming increasingly important to model the ionosphere’s behavior, he says, because “we’re getting more and more reliant on techmologies that are reliant on space weather.”28. What is the function of the newly-set antennas in Africa?A. To prevent possible distortion of the ionosphere.B. To analyse the weather changing records of the region.C. To improve internet connectivity in African rural areas.D. To monitor solar storms’ effects on radio communications.29. Which of the following is a “dangerous consequence” according to paragraph 2?A. Satellites may be destroyed.B. Crucial signals may be blocked.C. Bad weather may strike the earth.D. Charged particles may be weakened.30. What is paragraph 3 mainly about?A. The development of global weather models.B. The factors of accurate space measurement.C. The importance of collecting global climate data.D. The necessity of building multi frequency receivers in Africa.31. What is the best title for the text?A. The sun takes people on earth by stormB. Joint efforts in need to deal with solar stormsC. New space weather network extends over AfricaD. Africa on board to protect radio communicationsDHow could anyone dislike giving and receiving gifts? A good gift can be totally life changing. Gifts are so meaningful that some people identify “receiving gifts” as their primary“love language”.Indeed, on the surface, gift-giving occasions seem like wonderful opportunities to experience and create delight. But according to a 2023 survey, gift-giving and receiving is actually the least popular love language overall.The problem is that occasions that involve gift giving are full of uncertainty. If it’s an occasion like Christmas, where people are shopping for each other at the same time, people might still be nervous about whether the gift they give will be in the same category as the gift they will also receive. For instance, you don’t want to give someone a gag (恶作剧) gift when they're giving you a sincere, heartfelt gift. Mismatched approaches to gift-giving are a common recipe for awkwardness.There can also be enormous uncertainty around how your gift will be experienced by the receiver. Imagine that a close friend is showing some signs of seasonal affective disorder, and you’re giving him a therapy (疔法) lamp as a gift. True, he may very well be appreciative, indicating that this is “just what he needed.” But what if he interprets the gift as an unwelcome piece of commentary on his affective state? One could imagine a reaction along the lines of “Gosh, I’m sorry I’ve been so unpleasant to be around,” The message we send is not necessarily the same as the message received.Worst of all, there’s the anxiety that comes with receiving gifts. If you are like me, you may have found yourself in a setting where you expect a lot of well-meaning but disappointing gifts are headed your way. There can be some fear that comes with knowing that you'll soon need to perform joy and appreciation. Even worse, you might worry that the gift-giver will detect your in sincerity, wounding them in the process.It's not all bad, of course. When done carefully, gift-giving can be a wonderful way to draw people closer together, in a lasting way.32. Gift giving is full of uncertainty because ______.A. people prepare insincere gifts for othersB. the gifts they give are of the same categoryC. people shop for gifts for different occasionsD. mismatched gift- giving frequently happens33. An example of the therapy lamp is used to illustrate ______.A. trust can be earned through gift-givingB. misunderstanding can arise from gift-givingC. harmony can be achieved through gift-givingD. depression can be a byproduct of gift-giving34. What makes a gift-receiver most anxious?A. Expressing disappointment over the gifts.B. Having pretended delight at the gifts uncovered.C. Expecting well-intentioned gifts from friends.D. Fearing to extend appreciation for the gifts.35. What is the author’s at titude towards gift giving?A. Supportive.B. Opposed.C. Objective.D. Unclear.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。

2020五升六语文暑假专项练习：记叙文综合训练(二)-人教部编版(含答案)
记叙文综合训练（二）风筝洪志明看到阿明、阿善、阿立、阿忠四个人拿着风筝的背影，消失在常常放风筝的小山上，他心里有一点点说不出的难过。
一学期以来，他寄住在舅舅家，和他们四个人混得比亲兄弟还要熟，每天一起读书，一起玩，一起到小山上放风筝，几乎没有一天不聚在一起。
现在爸爸跑船回来了，他要回自己的家，和爸爸住在一起。
虽然很高兴，可是一想到要和他们拆伙，心里就有些酸酸的痛苦。
他相信无论如何他们一定会来送他的，所以请爸爸先走，他一个人在舅舅家等，没想到等了很久还是没看到他们的人影，更没想到他们竟还有心情到山上放风筝。
他含着眼泪，沿着山下的小路往前走，强．（qiǎnɡqiánɡ）迫自己尽．（jǐnjìn）量不要往小山上看。
“阿万——”忽然他听到背后呼叫的声音。
他转头一看，只见他们四个人站在小山上向他挥手，四只风筝在他们身后，高高地升起。
风筝上面写着四个斗．（duǒduò）大的字——阿万再见。
阿善从后面跑过来，气喘吁吁地说：“我们把风筝系．（xìjì）在高高的树上，要让你走很远了，还看得见。
”好好保重他紧紧握着四个人的手，哽咽得说不出话来。
阿万怎么也没有想到大家会用这种方式跟自己道别。
走了很远了，风筝还在天上飘着。
他频频地回头，看那高高飞起的风筝，泪水沿着脸颊往下滑落，模糊了风筝上的字迹。

WritingThe Value of TimeA proverb says, “Time is money.” But in my opi nion, time is even more precious than money. Why? Because when money is spent, we can earn it back. However, when time is gone, it will never return. This is the reason why we must value time.It goes without saying that the time for our study and work is unusually limited. Hence, even an hour is extremely precious. We should make full use of our time to do useful things. As a student, I must make efforts to engage in my study so as to serve our nation and people in the future. But it is a pity that there are a lot of people who do not know the importance of time. They do not realize that wasting time is equal to wasting a part of their valuable life.In a word, we should form the good habit of saving time. Do not put off what can be done today till tomorrow. Laziness will not only bring us failure but also lead us to the road of poverty.Ⅱ.

WritingGreen OlympicsOlympic Games, as we all know, is a historic sports meeting. “Green Olympics”, is one of the three themes of 2008 Beijing Olympic Games. At present, people s life is being flooded with exhaust gas from automobile, waste water from factories and so on. Owing to these phenomena, we should advocate “Green Olympics”, and I am positive of this point.Two possible reasons are as follows. Firstly, environmental protection benefits people s health. In terms of increasing number of trashes around us, such as white plastic bags, one off cups and chopsticks, it is sensible of disposing of them reasonably. So we ought to use clean technology, renewable and recyclable materials. Secondly, environmental protection is crucial to our country, and even to the world. In recent years, natural disasters, like tsunami in $2 and snowstorms in $2, are partly due to the disturbance of the environmental balance.In conclusion, as college students and the young generation, we should try our best to advocate “Green Olympics”. The 2008 Olympic Games should be a green and unique Olympics.Ⅱ. Reading Comprehension(Skimming and Scanning)1-7 BCDACDC8. $29. poems10. reindeer(with a disturbing red nose)Ⅲ.

WritingThe Heavy Burden of StudyNowadays, we often hear students complaining about the ever increasing pressure of their studies. The school bags on their backs are getting heavier and heavier, the hours spent on their assignments (are) longer and longer, and the after class activities (are) few and far between. The reasons for such a heavy burden, however, are various. On the one hand, parents have a strong desire for the early intellectual achievement of their children, thus, forcing them to read more and work harder. On the other hand, all teachers wish their students academic records better than others, because it is the main criterion to evaluate their work, so that they assign more exercises and homework for their students to do after class.We should take measures to solve this problem. First, the existing testing system should be reformed. Second, more attention should be paid to the development of personal quality and overall abilities instead of mere score on the examination papers. Only by doing these can we relieve students burden of study.Ⅱ.

Questions(1) Soon after he volunteered for military service, he received a book and a letter from this woman.(2) She declined his request and explained her objection.(3) She wanted to make sure that John didn t love her just for her beauty.Part TwoⅠ. WritingCompetitionCompetition makes people more creative and effective. It urges them to plan better, to try harder, and to achieve more. With a desire to excel in their work, people tend to perform more creatively and more efficiently.Competition helps produce better products and provide better services. In the present world of intense competition, every manufacture tries his best to outmatch his competitor by producing goods of better quality at lower costs. As a result, consumers pay less and receive better service. Competition promotes further development of society. If there were no competition, people would remain complacent and be unwilling to make any efforts or risk anything new. However, with fierce competition going on, they exert themselves to accomplish more. Their accomplishment will, in one way or another, contribute to the progress of society.Ⅱ.

WritingFor Better Understanding between Parents and ChildrenWith a steep rise in numbers of children who leave their kith and kin, the problem of lacking of understanding between parents and children has aroused general concern in recent years. And better understanding between the two generations is called for in society.So what causes this situation? First, it comes from the generation gap. Growing in different times leads to great difference in interests between the two generations. For example, R&B, about whichmany teenagers are crazy, is decadent music in their parents eyes. And meanwhile, teenagers can t stand the boredom and dullness in their parents life. Second, the reason is the lack of communication. Nowadays, parents slave to earn money and spend less time to talk with their children. And the children think it just an excuse of not concerning about them. Third, the reason is the pressure. As most children are from only child families, their parents baby them, hoping they will be successful in the future. But in fact, the pressure makes children depressed and heedless of advice.To solve this problem, efforts should be made by both sides: For parents, they should try to listen to their children with patience to find out what they really want; and for children, they just remember that what their parents do is all for their sake. And then the conversation between parents and children will be much easier and better understanding can be available.Ⅱ.

WritingMy View on Going after FashionNowadays, some college students like to go after fashion. Boy students wear long hair and blue jeans and girl students wear short hair and mini shirts. Whenever a new fashion appears on the street, these young people will just follow it without considering whether it is suitable to them or not. In their eyes, fashion is the symbol of the young generation.However, some other students prefer to go their own way. They pay little attention to the common taste of fashion. They often seek the styles they really like. Though sometimes what they wear is quite different from others, they do look great and nice.As to me, I don t like to go after fashion. Though fashion, in some way, may show a tendency of common taste, it depersonalizes people by making people everywhere look alike. I think only those who lack confidence will try to show their existence by these outside presentation. As college students, we should find ourselves and be ourselves. That will be the only kind of fashion that really counts.Ⅱ. Reading Comprehension(Skimming and Scanning)1-7 CBCBADC8. the educational under achievement9. working with the family10.

WritingOn StressWith the fast pace of modern life, more and more people are living under great pressure. Some people are afraid of pressure. They think that the stresses and strains of work deprive them of joy and happiness. In their view, stress does harm to them both physically and mentally. That is why they prefer something less competitive and strenuous to something more demanding and challenging.Others argue that stress isn t as bad as it is often supposed to be. Unless it is overwhelming, a certain amount of stress is vital to provide motivation and stimulation. Without stress, you may slack off and idle away your time. It gives purpose and meaning to an otherwise meaningless, dull life. People under stress tend to bring their potential into full play and to realize their goals.In my opinion, we shouldn t escape from stress but to face it as it is.

WritingAdvantages of a Job InterviewNowadays, when a person is hunting for a job, there will always be a job interview and I think the job interview has a lot of advantages.

Then the interviewee can decide whether the job is really suitable for him. Second, I think the job interview is a good chance for the interviewee to show both his ability and confidence. Then the interviewer can figure out whether he is the right person for the job.In a word, I think the interview will do good to both the interviewer and the interviewee.

WritingNo Pains, No GainsNearly every civilization has its own equivalent to the proverb “No pains, no gains.” It means that nothing can be gained without painstaking efforts and that no knowledge or skill can be acquired without sweat or toil.You don t have to look very far to prove the truth of the proverb. Darwin s great discovery was not the work of a moment but was preceded by years of patient, arduous observation. Mozart was not an accomplished pianist at the age of eight as the result of watching countless hours of TV. Nor did $2 make himself the greatest inventor in the modern world by spending his spare time on going to parties or bars. His words “Genius is 99 percent perspiration and one percent inspiration” reveals the secret of thousands of successful men and women. All accomplishments and success come from sustained endeavor.Although it is an old saying,“No pains，no gains” has its profound and realistic significance in our college studies. To acquire knowledge in a particular field and to attain any academic goals, great exertion and persistent effort are undoubtedly required because we all know that “No pains, no gains.”Ⅱ.

WritingInformation SecurityThe human beings are stepping into the information society. The information industry develops very rapidly, so do the hackers, trick playing teens, exploring children, fraudsters, and serious white collar criminals. Thus, information security becomes an impending important issue.In case of information breach, the victims—government departments, organizations or institutions, or companies will inevitably suffer great or small loss. Government may be threatened with national security. Companies may lose opportunities to develop new projects. And the public s and users confidence will be damaged.Then how to deal with this issue? Technology is only a partial solution to information security. What s more important is that organizations and companies should promote the awareness on information security to its staff. However, since no system can ever be 100 percent secure, a prevention only approach to information security management is not enough. Companies and organizations should adopt a dual approach to information security management by combing prevention and detection techniques.Ⅱ.
