【題目】 5G networks have been considered as one big thing for this century. They allow people to get faster services. Downloading information takes only seconds, instead of minutes.

But no true 5G phones are able to be used now. It won’t work with 5G until such services are built. Users will need an adapter to bring in 5G signals. There’s completely no need for users to worry about the safety of 5G signals.

Where will we probably see 5G first? The answer is in our living rooms. The speeds, about 20 times faster than the standard home Internet connection, are very likely to do wonders in our living rooms. Many users are tired of spending $100 or more monthly in booking cable(有線的) TV. They no more choose cable TV and begin to use streaming(在線播放) services connected to their broadband(寬帶) service instead.

Besides faster access, connectivity might get a little cheaper in future for users only if a complete 5G network is set up. However, the cost of programs and apps will go up. Meanwhile, users are in great need of ordering more monthly services. Comparatively speaking, users are likely to pay more for 5G services.

So far now, it’s mainly used at home.

【1】People can feel 5G’s advantage directly by its _____.

A. surprising speedB. comparatively low cost

C. powerful functionD. convenient Internet connection

【2】Why are 5G phones not widely used today?

A. Because services are limited.B. Because special equipment isn’t built yet.

C. Because 5G signals are not strong enough.D. Because the safety of 5G signals is not for sure.

【3】What will the writer probably write about next?

A. 5G’s role.B. 5G’s history.C. 5G’s influence.D. 5G’s development.

【4】Where does this passage probably come from?

A. A story book.B. A science fiction.C. A popular science book.D. A research report.

【答案】

【1】A

【2】B

【3】D

【4】C

【解析】

【1】細(xì)節(jié)理解題。根據(jù)短文第一段They allow people to get faster services. Downloading information takes only seconds, instead of minutes.可知，人們對5G網(wǎng)絡(luò)的直接感受就是“快”，故應(yīng)選A。

【2】細(xì)節(jié)理解題。根據(jù)短文第二段中But no true 5G phones are able to be used now. It won’t work with 5G until such services are built. Users will need an adapter to bring in 5G signals.可知，現(xiàn)在還沒有真正的5G手機(jī)，因?yàn)樵?/span>5G服務(wù)建成之前，它無法與之兼容，用戶需要一個適配器來接收5G信號。由此可知應(yīng)選B。

【3】推理判斷題。短文最后So far now, it’s mainly used at home.作者提到，到目前為止，5G主要在家里使用。那么接下來作者可能會討論它以后的發(fā)展，它的使用范圍將會更廣。由此可知D選項符合文意。

【4】推理判斷題。A story book故事書；A science fiction.科幻；A popular science book.一本流行的科學(xué)書；A research report.研究報告。根據(jù)文意可知，短文給我們介紹了5G技術(shù)的優(yōu)點(diǎn)和缺點(diǎn)，普及了有關(guān)5G的知識，這樣的短文應(yīng)來自科學(xué)書籍，故應(yīng)選C。

Only sometimes Chip's behavior really scared her. It was clear to both Chip and me that she really meant it.

I put my left arm on his shoulders and the right hand on his heart. I told him how wonderful and lovely I saw him to be. I praised how special and brave he was to express his hurt feelings.

【題目】 Aren’t mobile phone, e-mail and voice mail supposed to help us communicate more easily?Sadly,that’s not always the case.Take the other day for example ,when I was walking through the park with my friend ,suddenly his mobile phone rang and he answered it-leaving me alone and cutting our conversation dead!In fact ,the park was filled with people talking on their mobile phone .They were passing other people without even looking at them, or stopping to walk their dogs. Clearly, people preferred talking on the phone to face-to face contacting.

Why is it that the more, connected we get, the more disconnected I feel? New communication technology seems to keep people away from each other. With e-mail over the Internet. We can communicate without seeing or talking to one another. With Wechat or QQ, you can have conversations without even meeting that person. Even some food stores are using self- scanners(自助掃描儀) so that you can check yourself out。 As the contact(聯(lián)系) between human beings becomes automated自動化的)， my feeling of being disconnected gets stronger. Don’t get me wrong. I'm not against machines. I also own a mobile phone, a QQ, a Wechat and an e-mail account. Giving them up isn't a good idea,as they are useful to have around, It's just that when they keep us away from human contact, I begin to feel sad. More and more, I find myself answering e-mail instead of talking to people. The technology that helps keep us in contact with each other is, in fact making me feel more lonely.

What is to be done? Well, try to use less technology: no e-mailing people who live nearby, and no letting QQ and Wechat catch you all the time.

【1】The purpose of the example in Paragraph 1 is to show that people________.

A.communicate more easilyB.dislike talking face to face at all

C.prefer talking on their mobile phoneD.are good at using mobile phones

【2】The underlined word"disconnected"in Paragraph 2 probably means________.

A.lonelyB.satisfiedC.stupidD.interested

【3】It can be inferred from the Paragraph 2 that_________

A.technology keeps people busy than beforeB.technology is always useful to have around

C.the writer is going to give up phonesD.the writer would like to contact face to face

【4】Which is the best title of the passage?

A.Technology and Human LifeB.The Importance of Technology

C.Technology and Human ContactD.The Development of Technology
