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．

Harvard Library

14．Studying Abroad
Nowadays，studying abroad gains popularity in China．Many rich parents would rather send their children abroad to receive education than have them educated in China．
As every coin has two sides，studying abroad is not an exception（例外）．There are advantages for people to attend school abroad．In the first place，he can use the foreign language in his daily life so that his ability in the second language may be greatly improved，as it is obvious that there is no better chance to improve second-language than living in the country where it is spoken．While studying in a foreign country，he will most likely meet many others from overseas and it is possible to make friends from all over the world．This is not only exciting on the social level，but could lead to important overseas contacts in his career as well．He can get familiar with the knowledge updated in science and get the chance to use the first-rate facilities （设备） available．In this way，there is every chance that he is able to widen his horizon （眼界） and broaden his mind．
Of course，attending schools abroad may bring about a series of problems．The most serious problem is language barrier （障碍）．Most of the students who go abroad don't have enough skills in the language spoken there．As a result，on arriving there，they will find it difficult to understand what the teachers say．Besides，for lack of knowledge of the customs of the local people，they may constantly run into trouble in dealing with various situations．
Therefore，given an opportunity to attend a school abroad，one must consider both sides of the factors carefully before making up his mind．

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．

Pulitzer was born in Mako，Hungary．At 17，Pulitzer attempted to join the Austrian army，but was turned down due to age，bad health and poor eyesight．Disappointed but still with hope，he traveled first to Paris and then to London，hoping to join the army there．And he was rejected for the same reasons．Finally，he moved to the United States in 1864and served in the Lincoln Army when he was just 18until the end of the American Civil War．After the war he settled in St．Louis，Missouri，where in 1868he started working as a reporter for a German-language daily newspaper，the Westliche Post．He joined the Republican Party and was elected to the Missouri State Assembly in 1869．
In 1872．Pulitzer bought the Westliche Post for 3，000．Then，in1879，heboughttheSt．LouisDispatchfor2，700and merged （合并） the two papers as the St．Louis Post-Dispatch，which remained St．Louis'daily newspaper．He bought the New York World in 1883，which turned out to be a successful decision，and which made Pulitzer wealthy．In 1885，he was elected to the US House of Representatives，but resigned after a few months'service．In 1895the New York World introduced the first newspaper comic printed with colour．Under Pulitzer's leadership circulation （发行量） grew from 15，000to 600，000，making it the largest newspaper in the country．But unfortunately from 1890，Pulitzer's already failing health worsened rapidly and he withdrew from direct management of the newspaper，and simply gave some instructions from his vacation houses in Maine or in New York．At the age of forty，he was struck blind，but he still continued to run his press empire for twenty-two more years．
In 1892，Pulitzer offered Columbia University's president money to set up the world's first school of journalism．But the university turned down the offer．In 1902，Columbia's new president willingly accepted the plan for a school and prizes，but it would not be until after Pulitzer's death that this dream would come true．Pulitzer left the university $2million in his will，which led to the creation in 1912of the Columbia University Graduate School of Journalism．And up till now，Columbia's Graduate School of Journalism still remains one of the most famous in the world．
Joseph Pulitzer died aboard his sailing boat in 1911．He was buried in the Woodlawn Cemetery in The Bronx，New York．In 1917，the first Pulitzer Prizes were awarded，as Pulitzer wished to．
In 1989，in honor of his great achievements and contributions，Pulitzer was included in the St．Louis Walk of Fame．
