5．At thirteen，I was diagnosed （诊断） with a kind of attention disorder．It made school difficult for me．When everyone else in the class was focusing on tasks，I could not．
In my first literature class，Mrs．Smith asked us to read a story and then write on it，all within 45 minutes．I raised my hand right away and said，"Mrs．Smith，you see，the doctor said I have attention problems．I might not be able to do it．"
She glanced down at me through her glasses，"You are no different from your classmates，young man．"
I tried，but I didn't finish the reading when the bell rang．I had to take it home．
In the quietness of my bedroom，the story suddenly all became clear to me．It was about a blind person，Louis Braille．He lived in a time when the blind couldn't get much education．But Louis didn't give up．Instead，he invented a reading system of raised dots （点），which opened up a whole new world of knowledge to the blind．
Wasn't I the"blind"in my class，being made to learn like the"sighted"students？My thoughts spilled out and my pen started to dance．I completed the task within 40 minutes．Indeed，I was no different from others；I just needed a quieter place．If Louis could find his way out of his problems，why should I ever give up？
I didn't expect anything when I handed in my paper to Mrs．Smith，so it was quite a surprise when it came back to me the next day-with an"A"on it．At the bottom of the paper were these words："See what you can do when you keep trying？"

3．Be aware of those who use the truth to deceive．When someone tells you something that is true，but leaves out important information that should be included，he can create a false impression．For example，someone might say，"I just won a hundred dollars on the lottery．It was great．I took that dollar ticket back to the store and turned it in for one hundred dollars!"This guy's a winner，right？Maybe，or maybe not．We then discover that he bought two hundred tickets，and only one was winner．He's really a big loser!He didn't say anything that was false，but he omitted important information on purpose．That's called a half-truth．Half-truths are not technically lies，but they are just as dishonest．
Untrustworthy candidates in political campaigns often use this tactic．Let's say that during Governor Smith's last term，her state lost one million jobs and gained three million jobs．Then she seeks another term．One of her opponents runs an advertisement，saying"During Governor Smith's term，the state lost one million jobs!"That's true．However an honest statement would have been，"During Governor Smith's term，the state had a net gain of two million jobs．"
Advertisers will sometimes use half-truths．It's against the law to make false claims so they try to mislead you with the truth．An advertisement might boast，"Nine out of ten doctors recommend Yucky Pills to cure nose pimples（粉刺）．"It fails to mention that they only asked ten doctors and nine of them work for the Yucky Corporation．
This kind of deception happens too often．It's a sad fact of life：Lies are lies，and sometimes the truth can lie as well．

49．Which statement is true according to the article？B
A．Whenever people tell the truth，they may lie
B．The truth can be used in dishonest ways．
C．All governors help their states．
D．You cannot trust lottery agent．
50．The author clearly wants peopleD．
A．not to trust any politician
B．to vote for female candidates
C．not to believe advertisements of any kind
D．to think carefully about what they read and hear
