us how to fail so that failure becomes an experience that will lead to growth .we forget that failure is part of the human condition and that every person has the right to failure. most parents work hard at either preventing failure or protecting their chidren from the knowledge that they have failed. one way is to lower standards. a mother describes her childs hastily made table as “perfect”,even though it wobbles(摇晃)on uneven legs. another way is to shift blame. if john fails science, his teacher is unfair or stupid. the trouble with faiure prevention devices is that they leave a child unequipped for life in the real word . the young needno one can win all the timeand that it is possible to enjoy a game even when you dont win. a child whos not invited to a birthday party, who doesns make the honor roll or the baseball team, feels terrible, of course, but parents should not offer a quick consolation(安慰)prize or say, “it doesnt matter” because it does. the young should be allowed to allowed to experience disappointment and be helped to master it. failure is never pleasurable. it hurts adults and child alike. but it can make a positive contribution to your life once you learn to use it. step one is to ask “why did i fail?”resist the natural impulse to balme someone else. ask yourself what you did wrong and how you can improve .if someone else can help, dont be shy about inquiring. to learn that no one can be best at everying.36. this passage mainly tells us about _.a. the reason why people fail b how to fail c the ways to prevent failures d the importance of facing failures37.thesecondparagraphtellsus_.a.howamotherpraisedherchildrenb.twowaysoffailurepreventionmostparentsusedwhentheirchildrenfailc.howtoshiftblamed.parentsshouldblametheirchildrenatthepropertime38 when the writer says “every person has the right to fail”, he means “_-”a the world is full of failures b everyone makes mistakesc failures are not common in our lives d no one can grow up without failures39 by saying “protecting their children from the knowledge that they have failed”. the writer means that most parents try their best_a to let their children know that they wont fail.b to teach their children about the knowledge of failurec to provide their children with the knowledge against failure .d to keep their children from realizing that they failed.40 according to the passage , if you are facing failure ,you should _a blame someone else b face it yourself and not ask others for helpc forget it as soon as possible d think it over and find ways to improve it ( b )it feels like every time my mother and i start to have a conversation, it turns into an argument. we talk about something as simple as dinner plans and suddenly, my mother will push the conversation into world war iii. shell talk about my lack of a bright future because i dont plan to be a doctor. and much to her disappointment, i dont want to do any job related to science, either. in fact, when i was pushed to say that i planned to major(主修) in english and communications, she nearly had a heart attack.“why cant you be like my co-workers son?” shebemoansall the time. her co-workers son received a four-year scholarship and is now earning 70,000 dollars a year as an engineer. i dont know what to answer except that i simply cant be like mr. perfect as ive called the unnamed co-workers son. i cant be like him. im the type of person who loves to help out in the community, write until the sun goes down, and most of all, wants to achieve a career because i love it, not because of fame (名声) or salary.i understand why my mother is worried about my future major. ive seen my mother struggle to raise me on her small salary and work long hours. she leaves the house around 6:30 am and usually comes home around 5 pm or even 6 pm. however, i want her to know that by becoming a doctor, it doesnt mean ill be successful. id rather follow my dreams and create my own future.41. which of the following topics do the writer and his mother often talk about?a. the writers studies.b. the writers future jobc. dinner plansd. wars around the world42. we can infer from paragraph 1 that the writers mother _.a. doesnt want the writer to major in englishb. doesnt think the writer should be a doctorc. gets along very well with the writerd. doesnt think working in the science field is a good idea43. the underlined word “bemoans” in paragraph 2 most probably means _.a. agreesb. shoutsc. complainsd. smiles44. which of following statements is probable true ab; out the writer?a. he wants to be like his mothers co-workers son.b. he wants to find a job in his community in the future.c. he doesnt think his mothers co-workers son is perfect.d. he wants to do so something he really likes in the future.45 we can know from the last paragraph that_a the writers mother works very hard for the family b the writer doesnt know what his future will be likec the writer doesnt think being a doctor is good d the writer sometimes thinks his mothers advice is very good （ c ）a british judge ruled recently that swearing (咒骂) at the police is not a crime (犯罪), setting off a heated debate（辩论） across the nation.denzel cassiues harvey , 19 ,was stopped outside his home in hackney , east london , by police officers who thought he was carrying drugs. he was fined 50 by a count for repeatedly （重复）swearing at the police who were searching him for drugs.but judge david bean overturned(推翻) the decision of the previous（以前的） court . he said that police officers hear foul language too frequently to be offended （冒犯）. judge david bean said the foul language used by harvey was unlikely to cause the police officers harm , alarm or distress（苦恼）, because it was so “common”.the judge may have been right to cancel（取消） the fine in this individual case . but there are massive problems with what he said when making the ruling .foul language is frequently directed at police officers, but this doesnt mean that it should be accepted as part of their working life.how can we justify（证明） this ? there are the people who devote their lives to protecting us.what does it say about our respect for the police , if we see them as people who can be spoken to abusively (粗暴地) without a second thought?there are many times that police officers do not penalize member of the public for swearing at them and it would be impractical（不切实际的） to punish every person that abuses(辱骂) them with foul language .but if officers feel that someone has crossed the line , they should not be criticized for reacting（反应） to this . they are there to make these judgement and we need to allow them to do so.the question is not what is said, but how the language is used. if a person swears with genuine（真实的） aggression （进攻，侵犯）and aims to cause fear they should be penalized.the police are enforcers （实施者）of the law, not mute（无声的） punch bags.(沙袋)46 why was denzel cassiues harvey stopped by police officers? a because he was carrying drugs in his pocket. b because the police suspected that he was carrying drugs c because he swore at police officers on duty. d because he was a wanted criminal.47 what do you know about david bean ? a he is 19 years old b he offended police officers b he canceled the 50 fine d he was a police officer48 what does the writer think of judge david beans ruling ? a he disapproves of david beans ruling b he thinks it right for judge david bean to cancel the fine. c he thinks judge david beans ruling sounded reasonable. d he thinks highly of david beans ruling.49 what does the underlined word “penalize” mean ? a offend b abuse c criticize d punish50 which of the following is the best title ? a law needs to protect the police, too b swearing at the police should be banned c denzel cassiues harveys case set off a heated debate d judges are supposed to support the police （ d ）what exactly is a lie ? is it anything we say which we know is untrue ?or is it something more than that ?for example, suppose a friend wants to borrow some money from you. you say “i wish i could hel
