Would you give your Social Security Number to the clerk at the grocery store? Of course not, right? Yet, if you’re like most people, you wouldn’t hesitate to give out a different, but equally important number to the same person.
Experts now say that your cellphone number may be more pivotal than any other personal information in the eyes of spammers (垃圾邮件发送者) and identity thieves. In other words, instead of handing it out, you should guard that cellphone number with your life.
Today, your cellphone number will likely be with you for a very long time. That means if spammers get your cellphone number, it will be much harder to get rid of them. It also means that over the years, your cellphone number will be linked to a lot of personal information—from contact lists（通讯录) to bank card numbers, all information that hackers（黑客）would love to get their hands on.
A few years ago, German security researcher Karsten Nohl showed what he could obtain using only a person’s cellphone number. California Congressman Ted Lieu was given a new cellphone for a day and Nohl was given that cellphone number. Using just that number, Nohl was able to find Lieu’s location and movements throughout Los Angeles, read his emails and text messages, and record phone calls between Lieu and his staff. And Nohl did all of this from his office in Berlin using just a cellphone number.
Still think it’s a good idea to post your number on a noticeboard?
It’s safe to assume that Nohl is an expert when it comes to hacking, but even the ordinary thief can use your cellphone number to cause harm to you. When you sign up for an account online, you usually provide your email address and a password (密码). But if you forget that password, many of these companies will send you a password retrieval code (检码）via your cellphone. Let’s say you post something for sale online and you include your name, email, and cellphone number. You’ve now given a potential thief everything he needs to hack into any of your online accounts. Therefore, it just makes sense to protect yourself by guarding that number as closely as you would guard any other personal information.

Sudoku (数独) puzzles give your brain a hard time: Every number from 1 to 9 must appear in each of the nine horizontal (横向的) rows, in each of the nine vertical columns and in each of the nine boxes.
For many of us, this can be a reason for a headache, but in the very rare case of a German man, a Sudoku puzzle even caused seizures (痉挛).
In a new case study from the University of Munich, published in the Journal of the American Medical Association, Dr. Berend Feddersen introduces a student who was 25 years old when he was buried by a snow slide during a ski tour. For 15 minutes, he didn’t get enough oxygen, which severely damaged certain parts of his brain. “He had to receive treatment on the scene. Luckily he survived,” says Feddersen, the author of the study.
Weeks after the accident, when the young man was ready for recovery treatment, something bizarre happened: When the patient solved Sudoku puzzles, he suddenly had seizures of his left arm — something the medical world hadn’t seen before.
Feddersen explains: “In order to solve a Sudoku, the patient used parts of his brain which are responsible for vision-space tasks. But exactly those brain parts had been damaged in the accident and then caused the seizures once they were used.”
This particular case is an example of what doctors call reflex epilepsy (反射性癫痫), according to Dr. Jacqueline French, professor from NYU Langone School of Medicine.
“You have to have an injury of your brain first, and then seizures like that can happen,” she says.
In the meantime, the patient from the case study stopped solving Sudoku puzzles forever and has been seizure-free for more than five years. “Fortunately, he can do crossword puzzles. He never had problems with those,” Feddersen says.
1.In the accident, the student ______.
A. began to experience seizures in his left arm
B. got the vision-space part of his brain damaged
C. had to be sent to hospital as soon as possible
D. found his Sudoku ability seriously weakened
2.It can be learned from the text that ______.
A. the man cannot complete crossword puzzles now
B. it is Sudoku playing that brings about his seizures
C. the man’s symptoms are common and widely observed
D. the seizures cause much trouble to the man’s daily life
3.This text can be best described as______.
A. a medical test B. a warning to skiers
C. a news report D. a research paper
