You can send a message to someone on the other side of the world in just a few seconds. Moreover, it is not just text messages that can be sent quickly; images, videos, and even files can be shared with ease. This has made collaboration between people from different parts of theworld much more feasible.However, there are also some drawbacks to this rapid pace of communication.

I grew into adulthood and went to college.I had to ride the bus whenever I came home.Though the bus stopped about two miles from home,Dad never met me,even in severe weather.If I grumbled,he’d say in his loudest father-voice,“That’s what your legs are for!”The walk didn’t bother me as much as the fear of walking alone along the highway and country roads.I also felt less than valued that my father didn’t seem concerned about my safety.But that feeling was canceled one spring evening.It had been a particularly difficult week at college after long hours in labs.I longed for home.When the bus reached a stop,I stepped off and dragged my suitcase to begin the long journey home.A row of hedge (树篱) edged the driveway that climbed the hill to our house.Once I had turned off the highway to start the last lap of my journey,I always had a sense of relief to see the hedge because it meant that I was almost home.On that particular evening,the hedge had just come into view when I saw something gray moving along the top of the hedge,moving toward the house.Upon closer observation,I realized it was the top of my father’s head.Then I knew,each time I’d come home,he had stood behind the hedge,watching,until he knew I had arrived safely.I swallowed hard against the tears.He did care,after all.On later visits,that spot of gray became my watchtower.I could hardly wait until I was close enough to watch for its secret movement above the greenery.Upon reaching home,I would find my father sitting innocently in his chair.“So!My son,it’s you!”he’d say,his face lengthening into pretended surprise.I replied,“Yes,Dad,it’s me.I’m home.”5.What does the underlined word “grumbled” in Paragraph 1 probably mean?( )A.Admitted readily.B.Explained clearly.C.Agreed lamely.D.Spoke unhappily.6.What made the author feel uncomfortable was .A.the tiredness after long hours in labsB.the fear of seeing something movingC.the feeling of being less than valuedD.the loneliness of riding the bus home7.The author’s father watched behind the hedge because .A.he was concerned about his son’s safetyB.he wanted to help his son build up courageC.he didn’t want to meet his son at the doorwayD.he didn’t think his son was old enough to walk alone8.Which of the following can be the best title for the text?( )A.My Father’s Secret.B.My College Life.C.Terrible Journey Home.D.Riding Bus

process.You aggressively talk to people,give out your cards,call endlessly to schedule an appointment but have no real success from your efforts.To help you gain a different future,here are ten habits you should avoid.Ineffective networkers:ck patience.They expect immediate results and want business now,not tomorrow.2.Constantly “selling” something.They see dollar signs every time they shake hands with someone.3.Too many choices.If they offer a variety of products,they might try too hard to tell about all of them.Offering too much information sends a confusing message making it difficult for people to send referrals (指点).Opportunities are all around us but when you’re networking,only focus on one.4.Change positions too often.If they move from company to company or do something totally different,it might be difficult for people to keep up with them.ck manners and respect.They interrupt others,talk with food in their mouth,aren’t very polite and appear unprofessional.They call people during dinner or on the weekends without thinking whether the occasion is suitable.6.Distribute too many cards and sales literature.They come while loading with brochure flyers (传单),catalogues and samples.7.Focus on themselves.Too much self-promotion can leave the other person to feel unappreciated.Every sentence begins with “I” and is all about their business.8.“Taking” instead of “giving”.They don’t realize what other people sense when they are being very selfish.Others may think that they are being taken advantage of.ck authenticity (真实性)and personal values.They may create unrealistic expectations and not deliver on their promises.Sometimes doing things without integrity (正直)possibly twists the truth.10.Poor communication and interpersonal skills.They have trouble speakingeffectively,building relationships and following up.Networking is a process that is an investment of time and money.If you find you’re doing any of these habits,consider learning how to improve on these and maximize your results while networking.You’ll start to get better at connecting with people and obtain more referrals.1.According to the text,some people didn’t succeed in networking because .A.they didn’t make effortsB.they didn’t behave effectivelyC.they didn’t pay enough moneyD.they didn’t spend enough time2. According to the second habit,we shouldn’t when we are networking.A.make friendsB.talk about dollarsC.shake hands with everyoneD.pay attention to money only3.When talking with others,you should .A.give out your cards and brochures every now and thenB.talk about the quality of your product as much as possibleC.let other people express themselves completelyD.interrupt others when they make a mistake4.Which of the following is NOT correct about a salesman’s behavior?A.He offers too much self-promotion during the conversation.B.He considers when he can get what he expects carefully.C.He only focuses on one opportunity when networking.D.He keeps his promises and doesn’t expect too much from others.Ⅲ.阅读填句(2015郑州高三第一次质量预测)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。

see,there were always a great number of tourists visiting the shops,so I could always find someone 8 (interest) to talk with.And Joe,the owner of the bar below me,could always give me a little money to survive on in exchange for 9 (do) a few odd jobs for him.At the time,I suppose,I thought I was poor.Sometimes,we don’t realize how 10 (fortune) we are,do we?Ⅱ.阅读理解【人物传记类】Back in the day,the local library in Athens had an eight-book checkout limit.But there were exceptions.And young John Wood was one of them.In order not to prevent his hungry reading habit,the library increased his limit to 12 and John went on his merry way,gobbling up books the way most children do candy.It’s little wonder that today this successful social businessman likes nothing more than an airplane flight.It offers the ideal chance for a good read.Mr.Wood gets lots of flying reading time these days as the founder of Room to Read,a nonprofit program that has spent the past decade building children’s libraries and promoting literacy and education in some of the world’s poorest regions.Despite his love for books,there is nothing bookish about Wood.As a distance runner with a fondness for the outdoors,Wood was on a self-guided trek (长途艰苦旅行)across Nepal in 1998 when his future changed from the more usual path he had forged as a Microsoft marketing executive.On the first day of the 21-day trek,Wood had a chance to meet with a local education official.As they chatted at a teahouse,the official gave him an invitation to visit a local school.Off they went the next morning.While Wood was touched by the lack of the school’s resources,he was positively heartbroken by what passed for its library: The ragged collection of used books was kept under lock and key,so precious to the school were its contents.The headmaster looked at Wood and asked loud,“Perhaps,sir,you will someday come back with books.”Come back he did.First with his father,Woody,and nearly 1,000 pounds of books.And then he came back as the founder of a nonprofit program to provide books,schools,and libraries in Nepal.“The hardest thing is that there are 50 more countries that need Room to Read,” says Wood.Room to Read,which opened its 10,000th library earlier this year,raises all of its funds from private donors and foundations.Wood’s technology background has made his work particularly appealing to the philanthropists (慈善家).Earlier this year Tim Koogle,Yahoo’s founding CEO and now president of his own foundation,joined Wood on a trek in Nepal to celebrate Room to Read’s 10-year anniversary.Wood sees education as the path out of poverty,but he understands that it isn’t a quick solution.“Education is such a long-term one,” he says.“Part of the problem with the aid world is that it’s so focused on the short term.No one gets out of poverty on foreign aid.It’s always education.”1.Why was Wood allowed to borrow 12 books from the local library?( )A.Because he used to bring candy to the librarian.B.Because the librarian didn’t discourage him from reading.C.Because it was a rule for a businessman to borrow 12 books.D.Because he liked to eat books like candy.2.The students in the school Wood visited in Nepal .A.had no interest in the books in the libraryB.looked after their library books carefullyC.weren’t free to read books in the libraryD.had an urgent need for textbooks in class3.The attitude of Mr.Koogle towards Room to Read was .A.negativeB.indifferentC.neutralD.supportive4.From what Wood said,we know Wood .A.considered education to be most importantB.couldn’t wait to see the effect of his aidC.treated foreign aid as a solution to povertyD.planned to spend another 10 years helping Ⅲ.完形填空(2015青海平安一中高三第三次模拟) When I first met Alexander he said to me in Russian:“Nalei umye chai”=“Pour me

burned,it’s not only painful; it’s bad for your body.Burned skin cannot keep the bacteria out,so infections (感染)are common.Doctors often wrap burns in bandages for protection,but a recent study shows that a new kind of bandage can actually fight infection.Toby Jenkins,a scientist in England,worked on the study.Jenkins and his colleagues developed a material that contains tiny capsules (胶囊).To a bacterium,these capsules look like cells just waiting to be damaged.The bacteria attack the cells by releasing poisons.But when the bacteria attack the capsules,the capsules fight back—by releasing antibiotics (抗生素)that knock out any nearby bacteria.The material was tested on two types of harmful bacteria.When researchers placed pieces of the new material in a dish with the bacteria,the bacteria barely grew at all,which is unusual.This observation led the researchers to believe that the material really works.The scientists want the bandages to work specifically against dangerous bacteria,so they also tested the material on a harmless type of E.coli bacteria.When the material was placed in a dish with E.coli,the bacteria grew quickly—showing that it didn’t fool the harmless bacteria.This early experiment shows that the material can selectively kill dangerous bacteria,but it’s too early to start using the material in hospitals.“This is a nice approach and they’ve shown in principle that it works,” said Christopher Batich,a biomedical engineer in the US,who did not work on the study.While he’s excited about the results,he added that the real world is more complicated than this experiment.“You’d have to work with real bacteria and real wounds to see if it makes a difference,” he said.Jenkins and his colleagues are back at work improving the material.In the not-so-distant

being graded mainly on my ideas,and my friend helps me get my ideas across better in English.Is this OK?—MarianaA:It’s good that you want to succeed in your written work at college.Making use of available resources to help you succeed is a smart strategy(策略).But while you may believe that your instructors don’t care as much about how you write as they do about your ideas,that’s not a fair assumption.Certainly,your ideas are important.No matter how polished your writing is,it will not disguise a poorly expressed idea in a paper.But as a college student,being able to organize your thoughts clearly—whether you’re speaking in class or writing a paper—is critical to show that you’ve mastered the material in each course.This does not mean you shouldn’t ask others to review your written work before handing it in.That’s OK.You should not,however,allow a friend or anyone else to rewrite parts of your papers for you.Instead,ask them to simply let you know about any parts of the paper that are unclear and need work.Many colleges have writing centers where tutors will work with you on your writing —without doing the work for you.Regardless of whether you consult with a friend or a tutor,the right thing is for you to talk to your instructors to ask their advice and let them know you plan to seek assistance with your writing.If you ask them in advance for guidance on what’s appropriate and what’s not for the written work they assign,that will allow you to be as transparent as possible about how you complete your assignments.—Professor Byron5.What problem does Mariana meet?( )A.She has trouble learning English grammar.B.She wonders if her method on writing is suitable.C.She doesn’t get on well with her classmates.D.She isn’t able to express herself in English.6.According to Prof.Byron,what’s the most important in writing a paper?( )A.Professional advice.B.Polishing carefully.anizing thoughts.D.Familiar materials.7.When asking someone for help on your paper,you should ask him .A.to hand in the paper after reading itB.to write the difficult part for youC.to make a writing plan for youD.to tell you the part to be improved8.What does the underlined word refer to in the text?( )A.Essays.B.Courses.C.Ideas.D.Resources.。
