2017年雅思阅读理解习题
对于雅思考生来说，备考阅读理解非常重要，毕竟阅读理解难度大，而且占据了较多的分数。下面是小编为大家整理的一篇2017年雅思阅读理解习题，希望对大家有所帮助。
Hackers target the home front
1. One of the UK's leading banks has been forced to admit that organised hacking gangs have been targeting its executives. For the past year, Royal Bank of Scotland has been fighting systematic attempts to break into its computer systems from hackers who have sent personalised emails containing keyloggers to its senior management. This has included executives up to board level and is now the subject of a separate investigation by the Serious and Organised Crime Agency.
2. The hackers are homing in on the trend for people to work from home. The hackers make the assumption that the computers being used outside the work environment are more vulnerable than those protected by a corporate IT department.
Growing threat
3. For companies it is a growing threat as home working increases: a recent survey from the Equal Opportunities Commission found that more than 60% of the UK's population wants the option of flexible working.
4. And the hackers are employing increasingly sophisticated techniques. Each email they send is meticulously built to make it attractive to its target, who the criminals have carefully researched by trawling the internet for information. Once the email is composed, the malware is just as carefully designed: it is often modified to avoid detection by security software.
5. The keylogger contained in the email installs itself automatically and then collects details of logins and passwords from the unsuspecting user. This means that hackers can, using the usernames and passwords stolen by the keyloggers, connect to VPNs, or Virtual Private Networks, which many companies use to create an encrypted pathway into their networks.
6. Once inside a bank's network, the hackers can communicate directly with computers holding account information and manipulate funds.
7. Has this actually happened? In some cases sources claim that the login details of VPNs have been obtained and used though there has been no confirmation that any losses have occurred as a result. The attacks are not believed to have focused on RBS but to have been across the whole of the banking industry.
8. Royal Bank of Scotland said that the bank had suffered no losses as a result of the attacks and added: "RBS has extremely robust processes in place in order to protect our systems from fraud. Trojan email attacks are an industry-wide issue and are not isolated to a particular area or a particular bank."
9. It is not just banks that have been targets. Last year attempts were made to steal information from the Houses of Parliament using malicious email. Messagelabs, the company responsible for monitoring much of the email traffic of the government and big business for suspect software, said at the beginning of the year that criminals have been evolving more sophisticated techniques to attack corporate networks.
10. According to Mark Sunner, chief technology officer of Messagelabs, the number of malicious emails targeted at individuals has been increasing. Two years ago they were being seen once every two months, but now they are seeing one or two a day. This has been accompanied by an increase in quality in the creation of Trojans and spyware.
11. "The hackers are now aiming to take over computers, particularly those of home users. Some of the malicious software that we are routinely seeing for that purpose will have its own antivirus system built into it so that they can kill off the programs of their competitors."
Increased vigilance
12. Tony Neate, the head of Get Safe Online, a government-funded organisation set up to raise awareness among UK businesses of computer criminals, says: "There is now an attempt to target individuals within UK businesses - including the banking sector. What is happening is that crime is doing what it always does, which is look for the weakest link. Home working is where they perceive a weakness.
13. "This points to a need for increased vigilance and security by those working from home and by those responsible for letting them work from home. For home working to be effective, security needs to be as effective as if working in an office."

附：雅思阅读标题题如何解题?
读每段话时，要抓住该段话的主题句和核心词汇。正确答案常常是主题句的改写。
读每段话时，并不是该段落全要仔细阅读。这样，既浪费时间，也不容易抓住重点。应该抓住该段话的的主题句。先读该段话的第一句，然后，与选项列表中大各选项一一对应，确定正确答案，正确选项一般就该句话的改写。如果答案不能确定，应再读该段话的第二句，然后，与选项列表中的各选项一一对应。如果答案还是不能确定，应再读该段话的最后一句，再与选项列表中大各选项一一对应。如果还是找不到正确答案，则就需要阅读整段话了。根据统计，段落的主题句在第一句的可能性超过50%，段落的主题句在第二句的可能性超过20%，段落的主题句在最后一句的可能性超过20%。也就是说，按照上述方法做这种题型，读完该段话的第一句，就能在选项列表中找出该段话的Heading， 这种可能性超过50%。整段话都需要阅读的可能性不到10%。这个做题方法不仅有统计数据的依据，还有理论的基础。英文段落展开的方法比较简单，主要有两种：演绎法(deductive method)及归纳法(inductive method)。演绎法指的是由观点到例子及论据，所以主题句在该段话的第一句，但有时，第一句是个过渡性或描述性的句子，主题句有可能放在放在该段话的第二句，总之，主题句在第一句或第二句，都是deductive method.Inductive method 是指由例子及论据到观点，所以主题句在该段的最后一句，70%左右的段落使用deductive method写的，而且其中绝大部分主题句在第一句。20%左右的段落是用inductive method写的。
有的人会问：我怎么知道某段话是用演绎法写的，还是归纳法写的?是的，不读完整段话，是不知道的。但读完整段话，很浪费时间，而且，由于文章句子结构复杂，再加上有一些不熟悉的单词，很可能你也读不太懂。所以，若读完整段话在来选择该段的Heading， 不仅时间不够用，而且往往正确率也不高。
上面介绍的方法，就是按照概率，首先认为段落是用演绎法写的，而且主题句在第一句，按照第一句的意思，在选项列表中确定正确答案。如果选项列表中有一项与这句话的意思相同，即可认为是正确答案。如果不能确定，再依次读该段话的第二句和最后一句，再与选项列表中的各选项一一对应，确定正确答案。实践证明，这种方法不仅节省时间，而且正确率也很高。
