Maybe there’s spyware on the their computer, or a service they use suffered a security reach, leaving customers at the risk of exposure. Or perhaps their password is easy to guess.Don’t fear: You can easily set up proper defenses. Here’s how.● Clean Your Computer and SmartphoneBefore you put new security measures into place, make sure your devices are as spotless as possible. This means installing a good antivirus program and taking the time to clear out any spy — or malware that may have already infected your system. These days, it’s al so worth it to make sure your phone is safe from viruses. Iphones are less likely to be targeted by spyware, but Android users should download the Lookout app to scan their devices and ensure everything is as it should be.● Secure Your WiFi.It’s fairly easy for potential criminals to gain access to your information if they’re able to share your connection —that’s why you want to be careful when using public WiFi. Even though you put security measures into place a couple of years ago, it’s a good idea to refresh your settings.● Use passwordsWhat you’ve heard is true: Passwords should use a variety of special characters, numerals, letters, and cases when possible.● Check the shopping securityTake care when shopping online. Always check the security symbols when using an online site for shopping. If the lock icon encryption (加密) is not there, do not give out credit details. Also, check that the site is legal — never go to a site from a random email and start shopping online.Keep a separate credit card just for online shopping. This will make it easier to cancel if something bad does happen and your other credit card for “in real life” can still be used uninfluenced.Don’t store information on any store’s website. It may be convenient but it’s also a poss ible loss to you if the site is hacked.21.To put new security measures into place, we need to ___________.A. clear out everything in the systemB. make a random selection of networkC. get rid of potential spywareD. refresh the infected system22.According to the passage, the risk of exposing personal information may possibly be caused by___________.A. the applications of antivirus programsB. the practice of using public WiFiC. the difficult access to passwordsD. the separate credit card for online shopping23.Which of the following is an improper way to shop online?A. Adopting a unique password for every website.B. Shopping online at reliable websites.C. Keeping credit details safe by checking security symbols.D. Monitoring credit card by storing information online.BPhrases like “tiger mom” and ‘‘helicopter parent” have made their way into everyday language. Many of us find ourselves drawn to the idea that with just a bit more parental hard work and effort, we might turn out children with bright futures. But is there anything wrong with a kind of “overparenting style”? Parental involvement has a long history of being studied. Many of the studies, conducted by Diana Baumrind, a famous psychologist at the University of California, Berkeley, have found that a good parent is the one who is involved and reacts to her child in a positive way, who sets high expectations but gives her child independence. These “authoritative parents” appear to hit the sweet spot of parental invol vement and generally raise children who do better academically, psychologically and socially than children whose parents are not strict and less involved, or controlling and more involved. Why is this parenting style so successful?Authoritative parents actually help improve motivation in their children. Carol Dweck, a social psychologist at Stanford University, has done research that indicates why authoritative parents raise more motivated children. In a typical experiment, Dr. Dweck takes young children into a room and asks them to solve a simple puzzle. Most do so with little difficulty. But then Dr. Dweck tells some, but not all, of the kids how clever they are. As it turns out, the children who are not told they’re smart are more motivated to solve increasingly difficult puzzles. They also show higher levels of confidence and show greater progress in puzzle-solving.As the experiment suggests, praising children’s talents and abilities seems to shake their confidence. Dealing with more difficult puzzles c arries the risk of losing one’s status as “smart”. Dr. Dweck’s work strongly supports that of Dr. Baumrind, who also found that reasonably supporting a child’s independence and limiting interference (干涉) causes better academic and emotional results.The central task of growing up is to develop a sense of self that is independent and confident. If you treat your young child who is just learning to walk as if she can’t walk, you reduce her confidence. Allowing children to make mistakes is one of the greatest challenges of parenting. It is easier when they are young. The potential mistakes carry greater risks, and part of being a parent is reducing risk for our children. 24.According to the passage, a “tiger mom” ______.A. helps her children realize their dreamsB. speaks her children’s everyday languageC. places reasonable expectations on her childrenD. pays close attention to her children’s experiences25.It is implied that controlling style of parenting may _____.A. cause more problems in childrenB. foster independence in childrenC. face more challenges of childrenD. lead to children’s academic success26.The example of the children doing the puzzles suggests that ______.A. a good game plays a big role in training young mindsB. overpraising makes children less motivated and confidentC. puzzle-solving can give children the motivation they needD. bright children usually show less confidence in difficult games27.The last paragraph tells us that ______.A. children should not be given much freedomB. parents should not increase the risk of challengingC. parents should allow their children to learn from mistakesD. children should correct mistakes with the help of their parentsCA Special AppointmentYears ago I moved to Woodla nd Hills to take a job in a small hospital’s emergency department. No one wanted to work on Christmas Eve, so the shift (轮班) went to me. I kissed my family goodbye and went off to spend the night in the hospital. It was a thankless job.At 9 pm, the ambulance brought in a man in his 60s who was having a heart attack. His face was pale, and he was frightened. The whole night I did my best to save his life. Before I left in the morning to spend Christmas with my family, I stopped by to see how he was doing. It was still tough, but he had survived the night and was sleeping.The following year I got Christmas Eve duty again. At 9 pm sharp, the ward clerk told me there was a couple who wanted to speak with me. When I approached them, the man introduced himself as Mr. Lee and said, “You probably don’t remember me, but last Christmas Eve you saved my life. Thank you for the year you gave me.” He and his wife hugged me, handed me a small gift, and left.The following year a new doctor had joined the group, but I wanted to see if Mr. and Mrs. Lee would return. This time, I volunteered for the shift. I kept an eye on the door. Once again, at exactly 9 pm, the Lees appeared, carrying a warmly wrapped bundle. It was their new grandchild. Mr. Lee, his family and I spent 13 Christmas Eves together. In the later years the staff all knew about the story and would work to give me time with him in the break room, where we spent a half-hour each Christmas Eve.The last year I saw him, he brought me a gift. I carefully opened the package and found a crystal (水晶) bell inside. It was engraved (镌刻) with a single word: Friendship. Now, my family, friends and I ring that bell every Christmas Eve at exactly 9 pm and offer our best wishes to the man who we won’t forget.28.Working on Chr istmas Eve was considered “a thankless job” because ______.A. most patients were seriously illB. patients refused to express thanksC. doctors had nothing to do on that dayD. doctors couldn’t get praise for the hard job29.When the author left the hospital the next morning, Mr. Lee ______.A. was still in a state of dangerB. was really angry with herC. got ready to leave the hospitalD. recovered from his heart attack30.According to the passage, the author formed a habit of ______.A. celebrating Christmas Eve with her familyB. giving Christmas gifts to the hospital staffC. spending Christmas Eve with Mr. Lee in hospitalD. ringing the bell for patients in the emergency department31.Why does the author ring the bell on Christmas Eve?A. To honor her working experience.B. To tell kids the traditional custom.C. To remember an old friend of hers.D. To show the beginning of the holiday.DImagine you are standing on the 70th floor of the Empire State Building, staring at the cityscape. Suddenly a man pushes past you, opens the window and announces his intention to jump. You yell out, “Stop! Don’t do it!” the six-foot-five figure turns to you and menacingly (恐吓地) says, “Try to stop me and I’ll take you with me!”“Umm… No problem, sir. have a good trip. any last words?”“Let me tell you my troubles,” he says, “my wife left me, my kids won’t talk to me, I lost my job and my pet turtle died, so why should I go on living?”Suddenly you have a flash of inspiration. “Sir, clo se your eyes for a minute and imagine that you are blind. No colors, no sights of children playing, no fields of flowers, no sunset. Now imagine that suddenly there’s a miracle. You open your eyes and your vision is restored! Are you going to jump? Or will you stick around for a week to enjoy the sights?”“I’ll stay for a week.”“But what happened to all the troubles?”“I guess they’re not so bad. I can see!”“Well, your eyesight is worth at least five million dollars. You’re a rich man!”If you really appreciate your eyesight, the other pains are insignificant. But if you take it all for granted, then nothing in life will ever truly give you joy. Actually, there are misconceptions on the road to happiness. misconception1: “Once I know the tools for being happy, then it will work like magic.”Don’t expect the results to come automatically. It is possible to understand how to achieve happiness, yet not put it into practice. In fact, many people actually prefer to be comfortable and unhappy, rather than bear the discomfort of changing their habits. Just as learning any new skill requires effort, you have to be willing to invest serious effort to achieve real happiness.Misconception 2: “if I become content and satisfied with what I have, I’ll lose my motivation to achieve more.”Now ask someone who is depressed, “Let’s go fishing!” “I’m tired. Maybe tomorrow. And anyway, I might rain…” in reality, happy people are energetic and ambitious. There’s never enough time to do everything they want to do.Misconception 3:A beautiful Sunday afternoon, you’re in the park having a picnic with friends. Suddenly one person complains: “who forgot the forks? It’s too hot for volleyball. I want to go home already.”When our mood negatively affects others, we recognize we have duty to be happy and not spoil the fun. But what about when we’re at home with our family? Or when we go into the office on Monday morning? like an open pit in the middle of the road, a sourpuss(牢骚满腹的人) is a public danger. Being happy is part of being considerate to the people around us.32.The story is placed at the beginning of the passage in order to .A. tell a skill of persuasionB. warn the danger of standing on a tall buildingC. emphasize the importance of eyesightD. introduce the theme of the passage33.What can be inferred from the underlined sentences?A. Everything has a price.B. We should value what we have.C. Every dog has its day.D. Eyesight is more important.34.What is right about happy?A. Happy is a gift.B. Happy is limited.C. Happy is contagious (会传染的).D. Happy is no more than a skill.35.The best subtitle of Misconception 3 is .A. If unhappy occurs at home, I needn’t pretend to be happyB. If I can’t make others unhappy, I won’t be happy.C. If someone is happy, then others around them are happy.D. If I want to be depressed, that’s my own prerogative.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,选项中有两项为多余选项。

2016年山东省青岛市平度市高考英语模拟试卷(五)II.第一节阅读理解(满分30分,每小题6分)1. Every year, millions of Americans see their personal information leak into the wrong hands.Maybe there's spyware on the their computer, or a service they use suffered a security reach, leaving customers at the risk of exposure.Or perhaps their password is easy to guess.Don't fear: You can easily set up proper defenses.Here's how.●Clean Your Computer and SmartphoneBefore you put new security measures into place, make sure your devices are as spotless as possible.This means installing a good antivirus program and taking the time to clear out any spy﹣or malware that may have already infected your system.These days, it's also worth it to make sure your phone is safe from viruses.Iphones are less likely to be targeted by spyware, but Android users should download the Lookout app to scan their devices and ensure everything is as it should be.●Secure Your WiFi.It's fairly easy for potential criminals to gain access to your information if they're able to share your connection﹣that's why you want to be careful when using public WiFi.Even though you put security measures into place a couple of years ago, it's a good idea to refresh your settings.●Use passwordsWhat you've heard is true: Passwords should use a variety of specialcharacters, numerals, letters, and cases when possible.●Check the shopping securityTake care when shopping online.Always check the security symbols when using an online site for shopping.If the lock icon encryption (加密) is not there, do not give out credit details.Also, check that the site is legal﹣never go to a site from a random email and start shopping online.Keep a separate credit card just for online shopping.This will make it easier to cancel if something bad does happen and your other credit card for"in real life"can still be used uninfluenced.Don't store information on any store's website.It may be convenient but it's also a possible loss to you if the site is hacked.(1)To put new security measures into place,we need to________.A clear out everything in the systemB make a random selection of networkC get rid of potential spywareD refresh the infected system.(2)According to the passage,the risk of exposing personal information may possibly be caused by________.A the applications of antivirus programsB the practice of using public WiFiC the difficult access to passwordsD the separate credit card for online shopping.(3)Which of the following is an improper way to shop online?________A Adopting a unique password for every website.B Shopping online at reliable websites.C Keeping credit details safe by checking securitysymbols. D Monitoring credit card by storing information online.2. Phrases like"tiger mom"and"helicopter parent"have made their way into everyday language.Many of us find ourselves drawn to the idea that with just a bit more parental hard work and effort, we might turn out children with bright futures.But is there anything wrong with a kind of"overparenting style"?Parental involvement has a long history of being studied.Many of the studies, conducted by Diana Baumrind, a famous psychologist at the University of California, Berkeley, have found that a good parent is the one who is involved and reacts to her child in a positive way, who sets high expectations but gives her child independence.These"authoritative parents"appear to hit the sweet spot of parental involvement and generally raise children who do better academically, psychologically and socially than children whose parents are not strict and less involved, or controlling and more involved.Why is this parenting style so successful?Authoritative parents actually help improve motivation in their children.Carol Dweck, a social psychologist at Stanford University, has done research that indicates why authoritative parents raise more motivated children.In a typical experiment, Dr.Dweck takes young children into a room and asks them to solve a simple puzzle.Most do so with little difficulty.But then Dr.Dweck tells some, but not all, of the kids how clever they are.As it turns out, the children who are not told they're smart are more motivated to solve increasingly difficult puzzles.They also show higher levels of confidence and show greater progress in puzzle﹣solving.As the experiment suggests, praising children's talents and abilities seems to shake their confidence.Dealing with more difficult puzzles carries the risk of losing one's status as"smart".Dr.Dweck's work strongly supports that of Dr.Baumrind, who also found that reasonably supporting a child's independence and limiting interference (干涉) causes better academic and emotional results.The central task of growing up is to develop a sense of self that is independent and confident.If you treat your young child who is just learning to walk as if she can't walk, you reduce her confidence.Allowing children to make mistakes is one of the greatest challenges of parenting.It is easier when they are young.The potential mistakes carry greater risks, and part of being a parent is reducing risk for our children.(1)According to the passage,a"tiger mom"________.A helps her children realize their dreamsB speaks her children's everydaylanguage C places reasonable expectations on her children D pays close attention to her children's experiences.(2)It is implied that controlling style of parenting may________.A cause more problems in childrenB foster independence in childrenC face more challenges of childrenD lead to children's academic success.(3)The example of the children doing the puzzles suggests that________.A a good game plays a big role in training young mindsB overpraising makes children less motivated and confidentC puzzle﹣solving can give children the motivation they needD bright children usually show less confidence in difficult games.(4)The last paragraph tells us that________.A children should not be given much freedomB parents should not increase the risk of challengingC parents should allow their children to learn from mistakesD children should correct mistakes with the help of their parents.3. A Special AppointmentYears ago I moved to Woodland Hills to take a job in a small hospital's emergency department.No one wanted to work on Christmas Eve, so the shift (轮班) went to me.I kissed my family goodbye and went off to spend the night in the hospital.It was a thankless job.At 9pm, the ambulance brought in a man in his 60s who was having a heart attack.His face was pale, and he was frightened.The whole night I did my best to save his life.Before I left in the morning to spend Christmas with my family, I stopped by to see how he was doing.It was still tough, but he had survived the night and was sleeping.The following year I got Christmas Eve duty again.At 9pm sharp, the ward clerk told me there was a couple who wanted to speak with me.When I approached them, the man introduced himself as Mr.Lee and said, "You probably don't remember me, but last Christmas Eve you saved my life.Thank you for the year you gave me."He and his wife hugged me, handed me a small gift, and left.The following year a new doctor had joined the group, but I wanted to see if Mr.and Mrs.Lee would return.This time, I volunteered for the shift.I kept an eye on the door.Once again, at exactly 9pm, the Lees appeared, carrying a warmly wrapped bundle.It was their new grandchild.Mr.Lee, his family and I spent 13Christmas Eves together.In the later years the staff all knew about the story and would work to give me time with him in the break room, where we spent a half﹣hour each Christmas Eve.The last year I saw him, he brought me a gift.I carefully opened the package and found a crystal (水晶) bell inside.It was engraved (镌刻) with a singleword: Friendship.Now, my family, friends and I ring that bell every Christmas Eve at exactly 9pm and offer our best wishes to the man who we won't forget.(1)Working on Christmas Eve was considered"a thankless job"because________.A most patients were seriously illB patients refused to express thanksC doctors had nothing to do on that dayD doctors couldn't get praise for the hard job.(2)When the author left the hospital the next morning,Mr.Lee________.A was still in a state of dangerB was really angry with herC got ready to leave the hospitalD recovered from his heart attack.(3)According to the passage,the author formed a habit of________.A celebrating Christmas Eve with her familyB giving Christmas gifts to the hospital staffC spending Christmas Eve with Mr.Lee in hospitalD ringing the bell forpatients in the emergency department.(4)Why does the author ring the bell on Christmas Eve?________A To honor her working experience.B To tell kids the traditional custom.C To remember an old friend of hers.D To show the beginning of the holiday.4. Imagine you are standing on the 70th floor of the Empire State Building, staring at the cityscape.Suddenly a man pushes past you, opens the window and announces his intention to jump.You yell out, "Stop!Don't do it!"the six﹣foot﹣five figure turns to you and menacingly (恐吓地) says, "Try to stop me and I'll take you with me!""Umm…No problem, sir.have a good trip.any last words? ""Let me tell you my troubles, "he says, "my wife left me, my kids won't talk to me, I lost my job and my pet turtle died, so why should I go on living? "Suddenly you have a flash of inspiration."Sir, close your eyes for a minute and imaginethat you are blind.No colors, no sights of children playing, no fields of flowers, no sunset.Now imagine that suddenly there's a miracle.You open your eyes and your visionis restored!Are you going to jump? Or will you stick around for a week to enjoy the sights? ""I'll stay for a week.""But what happened to all the troubles? ""I guess they're not so bad.I can see!"________If you really appreciate your eyesight, the other pains are insignificant.But if you take itall for granted, then nothing in life will ever truly give you joy.Actually, there are misconceptions on the road to happiness.misconception1: "Once I know the tools for being happy, then it will work like magic."Don't expect the results to come automatically.It is possible to understand how to achieve happiness, yet not put it into practice.In fact, many people actually prefer to be comfortable and unhappy, rather than bear the discomfort of changing their habits.Just as learning any new skill requires effort, you have to be willing to invest serious effort to achieve real happiness.Misconception 2: "if I become content and satisfied with what I have, I'll lose my motivation to achieve more."Now ask someone who is depressed, "Let's go fishing!""I'm tired.Maybe tomorrow.And anyway, I might rain…"in reality, happy people are energetic and ambitious.There's never enough time to do everything they want to do.Misconception 3: _______A beautiful Sunday afternoon, you're in the park having a picnic with friends.Suddenly one person complains: "who forgot the forks? It's too hot for volleyball.I want to go home already."When our mood negatively affects others, we recognize we have duty to be happy and not spoil the fun.But what about when we're at home with our family?
