Would you give your Social Security Numb...

    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.

1.What does the underlined word “pivotal” in Paragraph 2 most probably mean?

A.Accessible. B.Familiar.

C.Important. D.Manageable.

2.What does the third paragraph mainly talk about?

A.Why people should protect their cellphone numbers.

B.Why people seldom change their cellphone numbers.

C.How to protect our personal information.

D.How to get rid of spammers.

3.What did Karsten Nohl’s show intend to prove?

A.Nohl is a real expert in hacking.

B.It’s necessary to fight against hackers.

C.Lieu’s new cellphone has powerful functions.

D.It’s easy to hack information via cellphone numbers.

4.What can we infer from the last paragraph?

A.It’s a good idea to sell something online.

B.It’s necessary to register several accounts online.

C.It’s common for people to forget their passwords.

D.It’s risky to post your cellphone number online.

 

1.C 2.A 3.D 4.D 【解析】 这是一篇说明文。文章通过卡尔斯滕•诺尔(Karsten Nohl)展示了通过手机号码获取信息很容易,对于黑客来讲通过手机号码窃取信息更加容易,呼吁人们应该保护自己的手机号码。 1.词义猜测题。根据第二段中In other words, instead of handing it out, you should guard that cellphone number with your life. 换句话说,你应该用你的生命来保护你的手机号码,而不是把它交给别人。可知,此处是描述你的手机号码很重要,比其他个人信息更重要,因此划线词的意思是“重要的”。故选C项。 2.主旨大意题。根据第三段中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.这也意味着,多年以后,你的手机号码将与许多个人信息相关联——从联系人列表到银行卡号码,而这些信息都是黑客们乐于获取的。可知,第三段主要讲述了为什么人们应该保护他们的手机号码。故选A项。 3.细节理解题。根据第四段中A few years ago, German security researcher Karsten Nohl showed what he could obtain using only a person’s cellphone number.几年前,德国安全研究员卡尔斯滕·诺尔(Karsten Nohl)展示了他仅凭一个人的手机号码就能获取的信息。可知,Karsten Nohl的例子展示了通过手机号码获取信息很容易。故选D项。 4.推理判断题。根据最后一段中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. 假设你在网上发布了一些待售的东西,并附上了你的姓名、电子邮件和手机号码。你现在已经给了一个潜在的小偷所有他需要的东西来黑进你的任何一个在线账户。由此推断出,把手机号码发到网上是有风险的。故选D项。

    In the fall of 2017, when Paula Aldridge needed to get a job, she found herself at a crossroads. The 50-year-old wasn’t sure she would ever work again, due to health issues.

But Aldridge’s life and career journey started to turn around after she connected with Goodwill of Central Iowa’s skills training programs. These programs are tailored to help people develop the kind of specific, real-world skills they need to get and keep a job, through a combination of detailed instruction and hands-on experience.

When Aldridge first connected with Goodwill in September 2017, she was dealing with several barriers to immediate employment. Transportation was challenging, as she didn’t have a driver’s license or own a car. Aldridge also had a limited work history with long employment gaps (间断) , meaning she missed out on learning important skills, such as working a credit card machine. On top of that, her physical health issues were also a problem.

According to Kayleigh Duff, a career specialist at Goodwill of Central Iowa, the biggest barrier Aldridge had to overcome was from within. “She said outwardly that she had all of this confidence and that she knew how strong a worker she was, but I don’t think she truly believed it herself.”

Thankfully, Aldridge had plenty of people on her side to provide motivation and guidance. She originally started off in the food service training program but was eager to enter the retail (零售) skills program, since she had previously worked at the Salvation Army and Subway. When Aldridge mentioned her interest in retail, Duff recognized that her go-getting attitude would be a perfect match for the program.

The seven-week retail skills training is a systematic program combining classroom instruction with on- the-job experience at a Goodwill store. As Aldridge progressed and graduated from the program, she became more confident in her abilities.

Duff said it was great to see how Aldridge grew into the devoted, driven worker she is today. “She has this strong desire, this longing to succeed. And she knows that she’s able to do that, although she has fallen short in the past.”

1.What can be learned about Goodwill’s training programs?

A.They combine theory with practice.

B.They guarantee a good job for participants.

C.They are designed mainly for the unemployed.

D.They were established in the autumn of 2017.

2.What was the biggest problem Aldridge faced according to Duff?

A.Poor health. B.Poor working skills.

C.A lack of confidence. D.A lack of a driver’s license.

3.Why did Aldridge change her training program?

A.She wanted to attend a more systematic program.

B.She wanted to gain some hands-on experience.

C.She was more interested in retail.

D.She followed Duff’s advice.

4.What’s the main idea of the text?

A.A 50-year-old devotes herself to Goodwill.

B.Goodwill helps a 50-year-old turn her life around.

C.Goodwill training programs spring up around the world.

D.Success is closely linked to appropriate training programs.
