Emily: Hi Joey. You look miserable today.
Joey: Hi Emily. I’ve been stupid!
Emily: What’s the problem Tell me about it.
Joey: Well, about two weeks ago I was considering buying a guitar online. I saw an online advertisement for a beautiful guitar at half price. It cost only 800 yuan!
Emily: Oh no! Don’t tell me you paid and it never arrived.
mis·er·able / m zr bl/ 痛苦的;非常难受的;可怜的;使难受的;使不舒服的;令人不快的
Joey: I wish that were so, Emily. Unfortunately, it’s much worse than that. The ad asked me to pay by scanning a QR code. I wasn’t sure how it worked, but they got my bank details after I scanned the QR code. Then my bank account was cleaned out. I lost all the money I had saved—5,000 yuan in total!
Emily: I’m so sorry. Did you report this to the police
Joey: Yes. I told the police as soon as I found out. They are now investigating the case. But I still feel bad. Why me
Emily: Don’t feel too bad. You’re not the only one to fall for tricks like this. As QR codes are widely used, QR code fraud is on the increase. In the digital age, it’s really
important to stay alert. Remember, if something seems too good to be true, it probably is.
Joey: I will certainly be more careful next time! Is there anything else I need to know

fall for sth信以为真 fall for sb爱上;倾心于
I'm surprised you fell for that trick.我感到惊奇,你竟中了那个诡计。
Emily: Well, criminals often put fake QR codes on websites or in smartphone apps. They may even stick fake codes on real ones, like they sometimes do on public bicycles. So check the code carefully.
Joey: Any other advice on not being taken for a ride
Emily: Yes. If you’re using a QR code to make a payment, pay close attention to the details shown before you confirm the payment. Also, you can install and register the National Anti-fraud Center app.
Joey: I see! From now on, I will remember to check twice and pay once! take sb for a ride欺骗;愚弄
B.Joey has found a website article about cybercrime. Read the article below and answer the following questions. P 9
Cybercrime: the dark side of the Internet
It was estimated that as of January 2021, there were 4.66 billion active Internet users globally, representing almost 60% of the world’s population. The Internet has, in a relatively short span of time, completely revolutionized how we communicate with each other, exchange information and conduct business. as from/of sth. 自...起;截至
rep·re·sent / repr zent/等于;相当于;意味着
Unfortunately, due to its wide reach and relative privacy, the Internet has become very attractive to criminals.
Consequently, cybercrime has become a huge problem in recent years. As most of us now use the Internet as part of our daily life, an awareness of cybercrime is essential,
if we want to avoid becoming a victim.
reach波及范围;影响范围
awareness (of sth)/ (that...)知道;认识;意识;兴趣
Cybercrime can come in many different forms. Phishing is one of the most common types of cybercrime. When clicking on links to dangerous websites or software, you
may be fooled into providing personal information such as passwords, usernames or financial details. Malware, another form of cybercrime, can cause damage or gain
illegal access to a computer or network.
phish·ing / f / 网络诱骗,网络钓鱼
malware/ m lw /恶意软件
access (对计算机存储器的)访问,存取
Cybercriminals trick you into parting with your money, infecting your computer with a virus to steal your personal data, or blocking you from accessing your own data until a ransom is paid. For example, in 2021, a computer manufacturer suffered a ransomware attack. Cybercriminals took advantage of a weakness in a server, accessed the company’s files and demanded a large sum of money.

part with sth放弃,交出(尤指不舍得的东西)

Fortunately, you can take preventive measures to reduce your chances of falling victim to such cybercrimes. Firstly, you need to stay alert when using the Internet.Do not provide personal information on a website you know nothing about, especially those that ask for your name, mailing address and bank account number. To avoid
getting taken in, be cautious about advertisements offering bargains and rewards that seem too good to be true. fall victim to sth.受伤;受损;被害
take sb in欺骗;蒙骗 bar·gain / bɑ ɡ n/ 减价品;便宜货
And, of course, do not open email attachments or click on
links from unknown sources, no matter how curious you might be! Secondly, you can turn to technical defences to protect yourself from cybercrime. Turn on your spam
blocker to prevent unwanted messages from getting to your inbox. Make sure you have reliable antivirus software and always keep it turned on.
spam blocker垃圾邮件拦截器
un·want·ed / n w nt d/ 不需要的;多余的;不受欢迎的;无用的
in·box / nb ks/ (电子邮件)收件箱, out·box发件箱
It is also a good idea to keep your software and operating system up to date by downloading and installing the latest security patches.
So, next time you go online, never drop your guard. Stay alert, smart and safe!
operating system(计算机)操作系统
up to date现代的;最新的;时髦的;新式的;拥有(或包含)最新信息的
patch补丁;补块
lower your guard/let your guard down/drop your guard放松警惕
1. How do you understand that cybercrime is “the dark side of the Internet”
Nowadays, we use the Internet to do many things, from shopping online to paying our bills. Though created with the intention to make our lives easier, the Internet is often misused by some people to harm others or even commit crimes.This is “the dark side of the Internet” referred to in the website article.
2. What preventive measures should we take to avoid falling victim to cybercrime
C.In pairs, discuss the problem of cybercrime. Use the following questions and expressions to help you.
We need to stay alert when using the Internet and turn to technical defences to protect ourselves from cybercrime.
What is cybercrime
What types of cybercrime are there Explain one type with a specific example.
What impact does cybercrime have on victims
How can we protect ourselves from cybercrime
Expressions: Expressing concerns
There is growing concern that …
The public are increasingly concerned about …
It greatly concerns/worries people that …
… has caused widespread concern.
… is of great concern to …
Possible answer
A: Do you know we’re at risk of becoming victims of cybercrime, that is, criminal activities involving our computers or other electronic devices
B: Yes, I know. As there’re about 4.66 billion active Internet users worldwide,cybercrime should be of great concern to us.
A: Right. Cybercriminals often commit crimes for financial gain. They use certain methods to gain access to our personal information, damage our computers or infect them.
gain好处;利益;改进;(尤指财富、重量的)增值,增加
B: Correct. Phishing is one common way they do that, but it certainly isn’t the only type of cybercrime. Have you heard of malware Cybercriminals use malicious software to block users from accessing their devices or data. A famous example is the global ransomware attack in 2017 which targeted computers running a popular computer operating system. The cyberattack affected 230,000 computers across 150 countries and caused 4 billion dollars in financial losses.
ma·li·cious /m l s/ 怀有恶意的;恶毒的
A: Unbelievable! It’s frightening that we can be targeted at the click of a button! I believe the public are now increasingly concerned about this issue.
B: Yes. As Internet users, we can take preventive measures against cybercrime. For instance, we should remain attentive when using the Internet.
at·ten·tive / tent v/ 注意的;专心的;留心的
We need to be more careful about entering personal information into unfamiliar websites and we should think twice before clicking on attractive advertisements, which may have viruses.
A: Exactly. Besides, there are technical defences in place.
enter sth (in/into/on sth)登记,登录,输入(姓名、号码、细节等)
think twice about (doing) sth三思而行;慎重考虑后再决定
in place在正确位置;准备妥当;在工作;准备就绪;在原地
Cybercrime greatly worries people, so nowadays, most computer software comes with built-in safety measures like spam blockers.
B: Also, it’s still a good idea to install reliable antivirus software and to always keep it turned on.
A: I agree. We must remember that cybercriminals are out there, even if we can’t see them. So, we must always be aware and take care!
built-in/in-built 是…的组成部分的;嵌入式的;内置的
safety measure安全措施;预防措施
D. Write an article calling on people to look out for cybercrime. Use your ideas from part C and the information in parts A and B to help you. Check and improve your writing after you finish it.
Cybercrime: don’t let it hack your life!
As of January 2021, there were around 4.66 billion active Internet users globally,representing almost 60% of the world’s population. Therefore, unsurprisingly, we all run the risk of experiencing cybercrime, the dark side of the Internet, in some way. Cybercriminals mostly commit
run the risk of (doing) sth冒…的危险;冒险(做某事)
crimes for financial gain. Through various methods they access our personal information and damage or infect our computers or other networked devices.
There are different types of cybercrime in the cyber world. One common type, phishing, occurs when we are encouraged to access dangerous websites or software
so criminals can gain our personal information.
net·work / netw k/v. 将…连接成网络;联播;建立工作关系
cyber / sa b (r)/(与)网络(有关)的
Once they have that information,criminals are free to use it as they please. Malware is another type that criminals
frequently use to damage our computers. The malicious software infects computers to steal personal data or block access. Businesses are popular targets. In 2017, a popular computer operating system was targeted, affecting 230,000 computers across 150 countries and causing 4 billion dollars in financial losses.
free (to do sth)能随自己意愿的;随心所欲的
please(常用在as或what、 where等词后)想,选择,喜欢
As Internet users, we have the power and means to avoid becoming victims of cybercrime. Having much knowledge about cybercrime can help prevent it. It is smart to stay informed of common types of cybercrime. It is also essential to take preventive measures. By staying alert when using the Internet, we can avoid accidentally providing personal information or clicking on dangerous links with tempting offers. offer(商店提供的) 特价; 赠品
informed/ n f md/见多识广的; 了解情况的;有根据的 (消息来源);明智的 (猜测或决定)
tempt·ing / tempt / 吸引人的;诱人的;有吸引力的
In this way, the chances of becoming a victim are reduced. Another important measure is to use the technical defences our computers offer. These include spam blockers, antivirus software and an up-to-date operating system.
The Internet will probably remain a vital part of our daily life, so we must protect it from being used as a criminal tool. Our collective actions will make a difference in reducing the growth of cybercrime. Through preventive behaviour, we can stop cybercrime from hacking our lives!
