18.Lead poisoning occurs when lead is presented in high level in the blood of a person.It is the most common medical problem found in children.And it's important to recognize the presence of lead in a child's body because lead is very harmful.
Children have the tendency to go around and put things in their mouth like paint.This is one of the main causes of lead poisoning.I also have found that children born in poor families have higher chances of getting exposed to lead.Lead can also be found in old water pipes and food and juice cans.
Some of the common symptoms of lead poisoning in children are headaches,stomach pain,hair loss,muscle weakness,weight loss,ect.
Lead poisoning can have severe effects and can lead to heart diseases,kidney diseases and other problems.It can also result in mental retardation and low I.Q.level.There have been cases where lead poisoning proves to be deadly for the child.
It's difficult to recognize whether a child is affected with lead poisoning easily,as the symptoms of this disease can occur due to some other medical problems.Therefore,children under the age of 6should regularly be checked to know the level of lead in their blood,through blood test.It's possible to completely cure a child with lead poisoning through treatment.Usually,oral medicines are given to the child,while sometimes,they're injected for reducing the lead level.Children who have very high level of lead in their blood would need treatment for a long period of time and would also be put on a special diet.
Parents have to take certain measures to lower the chance of lead poisoning in children.Cleaning the house regularly and removing shoes at the door,after coming from outside,will prevent the lead particles(微粒) from entering the house.Children should be put on a healthy diet,containing high proportions (比例) of calcium and iron,such as eggs,milk,fruits,potatoes,ect.which helps to keep the lead level in control,in the child's body.In short,parents should be careful and protect their children from the horrible consequences of lead poisoning.

分析 铅中毒是儿童中常见的疾病,辨别儿童体内铅的含量十分重要.本文讲述了铅中毒对儿童的危害,呼吁家长要谨慎,保护孩子免受铅的危害.

解答 71.poisoned  根据文章第一句话"Lead poisoning occurs when lead is presented in high level in the blood of a person"可知,如果血液中含铅量高,人会中毒.空格后有by  lead,所以用被动式poisoned.
72.uncommon  根据文章第一段中的第二句话"It is the most common medical problem found in children"可知,小孩铅中毒是很常见的,空格前有not,所以用common的反义词uncommon.
73.access 考查固定短语.根据文章第二段中的"children born in poor families have higher chances of getting exposed to lead"可知,来自穷人家庭的孩子更有可能有铅中毒的风险. have acess to 是固定短语,意思是可以接近.
74.Symptoms 考查归纳概括能力.根据第三段中的内容"Some of the common symptoms of lead poisoning in children are headaches,stomach pain,hair loss,muscle weakness,weight loss,ect."可知,空格右边都是铅中毒的症状,所以用Symptoms.
75.Effects考查归纳概括能力.根据文章第四段中的内容"Lead poisoning can have severe effects and can lead to heart diseases"可知铅中毒对人的身体有严重的影响.所以用effects.
76.cause   考查同义转换.文章中是  result in,意思是导致,用一个词代替就是cause.
77.regular    考查词性转换.根据文章最后一段中的第二句话"Cleaning the house regularly and removing shoes at the door"可知答案,空格处是修饰名词,所以用形容词形式.
78.reduce  考查词形转换.根据文章最后一段中的倒数第二句话"Usually,oral medicines are given to the child,while sometimes,they're injected for reducing the lead level"可知答案.空格前有不定式to,所以用动词原形.
79.treated   考查词性转换. 根据第五段的最后一句话"Children who have very high level of lead in their blood would need treatment for a long period of time"可知答案. 空格中应该用被动语态,所以用treated.
80.variety考查归纳概括能力.根据文章最后一段的第三句话"Children should be put on a healthy diet,containing high proportions (比例) of calcium and iron,such as eggs,milk,fruits,potatoes,ect."可知,应该给孩子各种各样的健康食物. a variety of是固定短语,意思是各种各样,多种多样.

19.When you are in a place where you are hunting for a new job or a career,you will find that there are several things that you should pay attention to.Jobs and careers are fewer than you expect,especially when satisfying employment is something you need to seriously think about.How are you going to find the job that you want and what should you avoid on your way?When you want to make use of your job search,take a moment and think about the things that you must avoid at all costs.
One of the most important rules is never to compromise on the things you ask for or desire or it will badly affect your life and peace of mind.Keep in mind your basic expectations of a dream job.They might be something about money or you might find they have something to do with time off.Whatever they are,make sure that you do not accept a job without them.Your requirements might not be easy to meet,but you have the right to try and achieve them.
What's more,don't shy away from odd(临时的)jobs that might actually take you to the place that you want to be in.Sometimes,finding the right job is a matter of luck and chance after you have been searching and putting in a lot of efforts.And if something unexpected happens,remember that taking the chance is of great importance and is something you might want to seriously consider.As long as you keep your goals in mind,you are going to be doing much better than other people during the job search.
If you are looking for the right job,another thing that you can do to make sure that you get the right kind of employment is to market yourself.When you do nothing to push yourself forward,you will be the one suffering for it.If required,give enough encouragement to yourself and try to confidently look at all that you have.Make sure that you can show your skills and abilities.If the jobs that you have set your sights on are challenging,set goals for yourself and work hard at them.The more efforts you put in marketing yourself,the more your chances of obtaining the job you like there will be.
Remember that when you are working on a job search,you should not short-change yourself.This is because you will only harm yourself by setting low goals.

9.High school dropouts (辍学者) earn an average of $9,000 less per year than graduates.
Now a new study moves away a common belief why they quit.It's much more than failing in
exams at school.
Society tends to think of high school dropouts as kids who just can't cut it.They are lazy,and perhaps not too bright.So researchers were surprised when they asked more than 450kids who quit school about why they left.
"The vast majority actually had passing grades and they were confident that they could have graduated from high school."John Bridgeland,the executive researcher said.About one million teens leave school each year.Only about half of African-American and Hispanic students will receive a diploma,and actually all dropouts come to regret their decision.So,if failing grades don't explain why these kids quit,what does?Again,John Bridgeland:"The most dependable finding was that they were bored.""They found classes uninteresting; they weren't inspired or motivated.They didn't see any direct connection between what they were learning in the classroom to their own lives,or to their career aspirations."The study found that most teens who do drop out wait until they turn sixteen,which happens to be the age at which most states allow students to quit.In the US,only one state,
New Mexico,has a law requiring teenagers to stay in high school until they graduate.Only
four states:California,Tennessee,Texas and Utah,plus tile District of Columbia,require
school attendance until age 18,no exceptions,another researcher,says raising tile compulsory attendance age may be one way to keep more kids in school.
"As these dropouts look back,they realize they've made a mistake.And anything that sort of gives these people an extra push to stick it out and it through to the end,is probably helpful measure."
New Hampshire may be the next state to raise its school attendance age to 18.But critics
say that forcing the students unwilling to continue their studies to stay in school misses the point--the need for reform.It's been called for to reinvent high school education to make it more challenging and relevant,and to ensure that kids who do stick it out receive a diploma that actually means something.
(Note:Answer the questions or complete the statements in NO MORE THAN 10WORDS)

81.What do people think of those who quit school?Lazy and not bright
82.Many students quit school not because they cannot pass grades but because they find
Lessonsuninteresting and not relevant to real life
83.Why don't some students quit until they are sixteen?Because that's the age to be allowed to quit
84.According to the passage,the more effective way to keep students from quitting is to
reform or reinvent high school education.
6.Parents who smoke often open a window or turn on a fan to clear the air for their children,but experts now have identified a related threat to children's health that isn't as easy to get rid of:third-hand smoke.
That's the term(36)Cto discuss the invisible yet poisonous mixture of gases and particles(颗粒) clinging(依附) to smokers'hair and(37)B,not to mention cushions and carpeting,that stays long after second-hand smoke has cleared from a room.The remaining(38)Aheavy metals,carcinogens(致癌物) and even radioactive materials that young children can get on their hands and take in,(39)Aif they're crawling or playing on the floor.

"Everyone knows that second-hand smoke is bad,(43)Athey don't know about this,"said Dr.Jonathan P.Winickoff,the lead author of the study and an assistant professor of Pediatrics at Harvard Medical School.
"When their kids are(44)Bthe house,they might smoke.Or they smoke in the car.Or they settle the kid in the car seat in the back and(45)Cthe window and smoke,and they think it's okay because the second-hand smoke isn't getting to their (46)C.We needed a term to describe these tobacco toxins(毒素)that aren't(47)A."

13.Interviewing someone for a job is not as easy as it looks.First,as the interviewer,you're tasked with finding the person who will not only do the job well but also fit in well with the other employees.
You have to make an evaluation of abstract qualities that can't be found on a résumé.Because you have to repeat the process for every potential employee,you end up asking question after question,applicant after applicant.
Still,interviewers need to be told something:"What is your biggest weakness?"is not a good question.It just isn't.
Now,job seekers have to understand that interviewers want to find some way to know what makes an applicant different from others.Asking questions that are seemingly impossible to answer is one way to see who can think creatively.Then what may be a proper way to respond to such a question?
Honesty,with a twist(新手法)
"‘What are your three strengths and three weaknesses?'is a classic,but not too many people know how to answer this,"says Kenneth C.Wisnefski,founder and CEO of WebiMax,an online marketing company.
"As an interviewer,we want to hear strengths that describe initiative(主动性),motivation and dedication.The best way to respond is to include these qualities into specific‘personal statements.'"
"Similarly,weaknesses should be positioned as a strength that can benefit the employer."
"I like to hear applicants state an exaggerated strength,and put an interesting twist on it.An example of this is,‘My initiative is so strong,that sometimes I take on too many projects at a time.'"
This answer leads with a strength that employers want-initiative-and still acknowledges that you're not perfect.
Although you might consider this acknowledgement too honest,it works because it proves you're being honest.
Honesty,with progress
When you consider what your weaknesses are,think about how you have attempted to overcome them.No one is perfect,so pretending that you are a perfectionist will come across as insincere.
Debra Davenport,author of"Career Shuffle,"believes citing(引用) examples are the best approach.
"My preferred response for this question is to tell the truth without damaging the applicant's image."Davenport explains.
"A better response might be,‘I've had some challenges with work-life balance in the past and I realize that a life out of balance isn't good for me,my family or my employer.I've taken the time to learn better time and project management,and I'm also committed to my overall wellness.'"
The answer adds some dimension to the question,and proves you've thought beyond the answer.You've actually changed your behavior to address the situation,even if you haven't completely overcome the weakness.
Put yourself in the interviewer's shoes
However you decide to answer,Debra Yergen,author of"Creating Job Security Resource Guide,"recommends job seekers imagine themselves sitting on the other side of the desk.
"If you were doing the hiring,what would you be looking for?What would be your motivation for asking certain questions?Who would you be trying to weed out?If you can empathize (共鸣) with the interviewer,you can better understand what they want and need,and then frame your qualifications to meet their needs for the position you seek."
Once you consider what the goal of the question is and figure out what your honest answer is,you'll be able to give the best possible answer to a tricky question.

☆Understand that the interviewers want to (74)distinguish between applicants and that asking a question seemingly impossible to answer is one way to see an applicant's (75)creativity.
☆Be (76)honest and inventive when asked about your weaknesses,and respond properly.
☆Never (77)pretend you are perfect,which may be believed to be insincere.
☆Try to show that you've changed a lot (78)though/althoughyou haven't completely get rid of your weaknesses.
☆Put yourself in the interviewer's shoes and have a better  (79)understanding  of their needs for the job.

3.Very few people were coming to eat at the White Rose Restaurant and its owner did not know what to do.The food in its restaurant was cheap and good,but nobody seem to want to eat there.Then he did something that changed all that,and in a few weeks his restaurant was always full of men with their lady friends.Whenever a gentleman came in with a lady,a smiling waiter gave each of them a beautiful menu.The menu looked exactly the same on the outside,but there was an important difference inside.The menu that the waiter gave to the men gave the correct price for each dish and each bottle of wine,while the menu that he gave to the lady gave a much higher price.So when the man calmly ordered dish after dish and wine after wine,the lady thought he was much more generous than he really was.
