Ⅰ.阅读理解
A
Programmes that drive the digital experiences today seem to turn to contents that are popular,but people may be unable to tell fact from fiction.And due to the fact that anyone can post anything they want online,unconfirmed reports and irresponsible and unchecked contents are common in the online world.The problem is so common that a British newspaper has a whole page contributed to contents about fake (假的) news.
During the past days when most kids used textbooks that had been edited and reviewed responsibly before they were used,the need for students to check the sources of information was not great. Today,it’s different.Students use the Internet for research,and teachers and parents can’t keep them away from bad contents all the time.And they’re on their own as they get older.They have to master infomation literacy (信息素养),the skills of recognising fake information,identifying true information,and understanding the difference between the two.
There are people and organisations dealing with the problem and developing information for Internet searchers,both adults and children.A website,for example,has provided Internet searchers with extra information on the results page.The move is intended to make people slow down and think twice before accepting search results as facts.
Fake news is here to stay.We all need to fight.We can start with awareness and a few rules:don’t make the Web full of fake information;don’t spread or share information if we aren’t sure about it.And be mindful of how we use information:practise information literacy.And human curiosity is of great importance in this fight against misinformation.Curiosity drives learning and makes people question information.We need everyone to join in researching and questioning the information.
(　　)1.What problem about the online world is described in Paragraph 1
A.Useless results often show up first online.
B.The online world is full of fake information.
C.Fake news is spread purposely to attract searchers.
D.Newspapers pay more attention to popular contents.
(　　)2.What does Paragraph 2 mainly talk about
A.The importance of information literacy.
B.The learning style of different generations.
C.The effect of networks on today’s students.
D.The reason for the existence of fake news.
(　　)3.What does the website mentioned in Paragraph 3 do for searchers
A.It protects their privacy.
B.It removes fake news.
C.It provides more details.
D.It corrects the search results.
(　　)4.Which of the following would the author agree with
A.We can’t speak freely in the online world.
B.It is unnecessary to clean up fake news.
C.We should keep curious to discover the truth.
D.It is hard to force people to follow the rules.

2.A　段落大意题。根据第二段的内容尤其是“They have to master information literacy(信息素养) ...between the two.”可知,本段主要介绍了信息素养的重要性。故选A。
3.C　细节理解题。根据第三段中的“A website...accepting search results as facts.”可知,网站已经在搜索结果页面为互联网搜索者提供额外的信息。此举旨在让人们慢下来,在接受搜索结果为事实之前慎重考虑。因此,提到该网站是为搜索者提供更多的细节。故选C。
4.C　推理判断题。根据最后一段中的“And human curiosity...questioning the information.”可推知,作者赞同我们应当保持好奇心,善于发现真相。故选C。
B
Wi-Fi has become an integral part of our fast-paced everyday lives.Thanks to Wi-Fi,we no longer have to be restricted to the Internet with cables.But have you ever stopped to wonder how it works
Wi-Fi uses radio waves to transmit information between your device and a router (路由器) via frequencies.Two radio-wave frequencies can be used,depending on the amount of data being sent: 2.4 gigahertz (千赫兹) and 5 gigahertz.What does that mean,though Well,a hertz is just a measurement of frequency.For example,let’s say you’re sitting on a beach,watching the waves crash to shore.If you measured the time between each wave crash,you’d be measuring the frequency of the waves.One hertz is a frequency of one wave per second.One gigahertz,on the other hand,is one billion waves per second.The higher the frequency,the greater the amount of data transmitted per second.
The two Wi-Fi frequencies are split into multiple channels so as to prevent high traffic and interference.When it comes to sharing the data across these channels,well,that’s when the magic computer science happens.The first step in the process is initiated by you.When you access the Internet on your device,it transforms the information you’ve requested into binary (二进制) code,the language of computers.Everything computers do is based on binary code,a series of 1s and 0s.When you click on this article,your request is translated into a bunch of 1s and 0s.The frequencies travel across the radio channels mentioned earlier and are received by the Wi-Fi router that your device is connected to.The router then transforms the frequencies back into binary code and translates the code into the Internet traffic that you requested,and the router receives that data through a hardwired Internet cable.The process repeats itself until you have loaded this article—or anything that requires the Internet.
(　　)5.What is the author’s attitude to the Wi-Fi access
A.Favourable. B.Tolerant.
C.Doubtful. D.Unclear.
(　　)6.Why does the author mention “sitting on a beach” in Paragraph 2
A.To make a prediction.
B.To clarify a concept.
C.To present a fact.
D.To offer a reason.
(　　)7.What is the focus of the last paragraph
A.The significance of measuring frequency.
B.The method of transmitting information.
C.The function of translating binary code.
D.The principle of sharing data.
(　　)8.What can be a suitable title for the text
A.When Does Wi-Fi Exist
B.What Does Wi-Fi Transmit
C.How Does Wi-Fi Work
D.Why Does Wi-Fi Matter
语篇导读:本文是说明文。文章主要介绍了Wi-Fi的工作原理。
答案及剖析:
5.A　推理判断题。根据第一段的第一、第二句可推知,作者对Wi-Fi持赞许的态度。故选A。
6.B　推理判断题。根据画线部分上一句“Well,a hertz is just a measurement of frequency.”可推知,作者举坐在沙滩上(sitting on a beach)的例子是为了帮助大家理解“赫兹”这个概念。故选B。
7.D　段落大意题。根据最后一段内容可知,最后一段主要是在介绍共享数据的原理。故选D。
8.C　标题归纳题。根据第一段的最后两句并结合全文可知,本文主要是在介绍Wi-Fi是如何工作的。故选C。
C
Screen time is often considered the enemy when it comes to teaching kids to be active.However,a new research found that for 9 and 10 years old children reasonable social media use was related to some positive effects,including increased physical activity,less family conflict (冲突) and fewer sleep problems.
The findings come from an analysis of data from about 4,500 young people and their parents collected by the Adolescent Brain Cognitive Development study.The study gathered information about how young people’s brains develop.
In the study,children self reported activities like watching TV,texting or visiting social media sites —and the time spent on each.They rated their time on them as never,once in a while and all the time.Kids and parents reported on family conflict.Parents also kept track of how well the kids slept and filled out a checklist that assessed (评定) their children’s behaviour.
The results haven’t been published yet,but are being presented at the Research Society on Alcoholism in San Diego.Previous research has been done largely in older kids or teenagers with less focus on younger munities and social networks can have beneficial effects,so kids who are reasonably using social media to build connections may see positive outcomes.
Do these findings mean that parents should ban TVs and sign their kids up for social media accounts Probably not.Psychologist Chris Ferguson of Stetson University says that the differences identified in the research are small.
(　　)9.What does the passage mainly talk about
A.More screen time is needed by kids.
B.Screen time is the enemy of teaching kids to be active.
C.Parents should ban TVs and sign their kids up for social media accounts.
D.A look at social media may have possible benefits for kids.
(　　)10.How did the researchers get the data they wanted
A.They carried out interviews.
B.They asked kids and parents to report.
C.They got the data from other scientists.
D.They downloaded the data from the Internet.
(　　)11.What is Chris Ferguson’s attitude towards the findings
A.Objective. B.Subjective.
C.Supportive. D.Doubtful.
(　　)12.Where is the text probably from
A.A novel. B.A travel guide.
C.A news report. D.A book review.
语篇导读:本文为说明文。文章主要介绍了合理的屏幕时间(使用社交媒体的时间)对儿童有益的研究发现。
答案及剖析:
9.D　主旨大意题。通读全文,特别是第一段内容可知,文章主要介绍了研究发现,合理的屏幕时间(使用社交媒体的时间)对儿童有益。故选D。
10.B　细节理解题。根据第三段内容可知,研究人员是通过让家长和孩子报告屏幕使用的时间情况来收集数据的。故选B。
11.D　推理判断题。根据最后一段内容可知,Chris Ferguson对该研究的发现持怀疑态度。故选D。
12.C　推理判断题。通读全文可知,文章主要介绍了合理的屏幕时间(使用社交媒体的时间)对儿童有益的研究,这属于科学研究范畴,因此本文最有可能出自新闻报道。故选C。

1.G　文章第一句点明不礼貌的手机用户随处可见,接下来应该会讲不礼貌的手机用户的行为是怎样的,承接上文,G选项切题,G选项中的“Most people who are impolite”对应上文的“Impolite cellphone users”。故选G。
