题目内容

【题目】 If you’re anything like the average American, you probably check your smartphone more than50 times per day as a 2018 study found. 1 In fact, The University of Arizona found back in2012 that cell phones carry 10 times more bacteria than a toilet seat, largely because toilet seats are typically cleaned more frequently while personal electronics are largely overlooked.

As the novel corona virus (新型冠状病毒) continues to spread, the Centers for Disease Control and Prevention and the World Health Organization are advising the general public to wash hands often and disinfect (消毒) frequently touched objects and surfaces. 2

But cleaning your phone can be tricky, considering many of the standard cleaning products you’d typically use for disinfection could potentially damage your mobile device. You may want to wipe down your phones screen with some rubbing alcohol or a disinfectant wipe. 3 These phones have a coating on then to prevent oil or grease from your hand from sticking on the phone. Using alcohol or those types of everyday solutions directly on a phone, on its glass can harm it. 4

That lines up with the advice Apple and Samsung offer which warn not to use cleaning products. 5 If you need to disinfect your smartphone, consider looking into a UV light to kill the bacteria.

A.Avoid using alcohol.

B.But in doing so, you risk damaging your devices screen.

C.That means keeping your phone clean is important as well.

D.You should still be cautious when exposing them to liquids.

E.Instead use a micro fiber cloth and dampen it lightly with soap and water.

F.And each time you do, your mobile device picks up more bacteria from your hands.

G.Both companies say wiping your phone down with a soft cloth is the best way to clean it.

【解析】

本文为说明文。文章叙述了手机上的细菌含量很高,但清洁手机要注意方法。

1】考查对上下文的理解及推理判断能力。根据前文“If you’re anything like the average American, you probably check your smartphone more than50 times per day as a 2018 study found”,以及下文“cell phones carry 10 times more bacteria than a toilet seat”如果你和普通美国人一样,你可能会象2018年的一项研究发现的那样,每天查看智能手机的次数可能会超过50次,手机携带的细菌是马桶座圈的10倍。可知,每次这样做,你的移动设备从你的手上收集更多的细菌。分析选项可知FAnd each time you do, your mobile device picks up more bacteria from your hands(每次你这样做,你的移动设备从你的手上收集更多的细菌)符合题意,故选F

2】考查对上下文的理解及推理判断能力。根据上文“As the novel corona virus (新型冠状病毒) continues to spread, the Centers for Disease Control and Prevention and the World Health Organization are advising the general public to wash hands often and disinfect (消毒) frequently touched objects and surfaces.”随着新型冠状病毒继续蔓延,美国疾病控制和预防中心和世界卫生组织建议公众经常洗手,对经常接触的物体和表面进行消毒。可知,保持手机清洁也很重要。分析选项可知CThat means keeping your phone clean is important as well(这意味着保持手机清洁也很重要)符合题意,故选C

3】考查对上下文的理解及推理判断能力。根据上文“considering many of the standard cleaning products you’d typically use for disinfection could potentially damage your mobile device. You may want to wipe down your phones screen with some rubbing alcohol or a disinfectant wipe.” 考虑到许多你通常用来消毒的标准化清洁产品可能会损坏你的移动设备。你可能想用酒精或消毒剂擦拭一下手机屏幕。由此可知,如果用酒精或消毒剂给手机消毒的话会伤害手机屏幕。以及下文“Using alcohol or those types of everyday solutions directly on a phone, on its glass can harm it.” 直接用酒精或那些日常解决方案在手机上、在杯子上使用会对身体造成伤害。可知,这样会损坏你的设备屏幕。分析选项可知BBut in doing so, you risk damaging your devices screen(但这样做,你就有可能损坏你的设备屏幕)符合题意,故选B

4】考查对上下文的理解及推理判断能力。根据上文“Using alcohol or those types of everyday solutions directly on a phone, on its glass can harm it.” 直接在手机上使用酒精或其他类似的日常解决方案会对手机造成伤害。所以要用超细纤维布,并用肥皂和水轻轻地润湿。分析选项可知EInstead use a micro fiber cloth and dampen it lightly with soap and water(取而代之的是使用一块微纤维布,用肥皂和水轻轻地将其浸湿)符合题意,故选E

5考查对上下文的理解及推理判断能力。根据上文“That lines up with the advice Apple and Samsung offer which warn not to use cleaning products. 这与苹果和三星提出的警告不要使用清洁产品的建议一致。以及下文“If you need to disinfect your smartphone, consider looking into a UV light to kill the bacteria.”如果需要给你的智能手机消毒,考虑使用紫外线来杀死细菌。分析选项可知GBoth companies say wiping your phone down with a soft cloth is the best way to clean it(两家公司都说用软布擦拭手机是最好的清洁方法)符合题意,且G项中Both companies与文中所提的“Apple and Samsung”两家公司是一致的,故选G

【题目】 I took a motor rickshaw to the train station in the city of Belapur. The driver didn't speak much English, but understood, "Belapur Railway Station. ” I had my tabla, a traditional drum from India, my suitcase with my clothes and other essentials. The feeling of flying by cars in this little machine is : as if you are inside a box with tiny wheels, dashing through disorderly traffic.

I arrived at the station safely, and took a heavy breath as I unloaded my baggage before the ticket office. It was the first time that I had taken a local train to Tilak Nagar, where I was going to learn traditional vocal music. Standing in line, I counted at least 20 people staring at me. I bought my ticket, which was only 55 cents for a 20-minute train ride. The prices still blow me away.

When the train came after 15 minutes or so, I got on with all speed, as the train only stops for a few seconds. The locals again stared at me. This was a train especially for local transport. After a while, a young man asked me if he could talk to me. He wanted to know if I was in a band. I stated no, but I love to play tabla. Through the conversation I knew he was a student of engineering with his exams being tomorrow, I wished him good luck for the exams sincerely, as I knew what it means to Indian students to get good marks on their exams. If students do not get good enough scores, job opportunities will be few in a highly-competitive environment.

The student I met helped me unload my luggage as the train reached Tilak Nagar Station. He shook my hand strongly and looked into my eyes with marks of genuine care and friendship, despite us meeting for only 20 minutes.

【题目】 When Wilbur and Orville Wright finished their flight at Kitty Hawk, Americans celebrated the brotherly bond. The brothers had grown up playing together, they had been in the newspaper business together, and they had built an airplane together. They even said they "thought together." However, when the Wright brothers said they thought together, what they really meant is that they argued together. After long arguments we often found ourselves in the position of each having been pulled to the other's side,"

Orville reflected. I don't think they really got mad," their mechanic (机械师) remembered, but they sure got awfully hot."

The skill to get hot without getting mad is critical in life. But it’s one that few parents teach to their kids. We want to give kids a stable home, so we tор blng (兄弟姐妹) from quаrrеlng and we have our own arguments behind closed doors. Yet if kids never get exposed to disagreement, we’ll end up limiting their creativity. As the psychologist Robert Albert put it, the creative person-to-be comes from a family that is anything but harmonious, one with a “wobble (摇晃).”Orville Wright came from a wobbly family. The brothers often watched their father Milton Wright fight with school authorities who weren't fond of his decision to let his kids miss a half-day of school from time to time to learn on their own.

The Wright brothers weren't t alone. The Beatles fought over instruments and tunes. Steve Jobs and Steve Wozniak argued constantly while designing the first Apple computer. Brainstorming groups generate16 percent more ideas when the members are encouraged to criticize one another. The most creative ideas in Chinese technology companies come from teams that have real disagreement early on.

Children need to learn the value of thoughtful disagreement. We should teach kids that silence is bad manners. It disrespects the value of your own view point and your own voice. It's a sign of respect to care enough about someone's opinion that you’re willing to challenge it. Good arguments are wobbly: a team or family might rock back and forth but it never tips over. If kids don't learn to wobble, they never learn to walk; they end up standing still.

1What does the author say about the Wright brothers?

A.They always took advice from their mechanic.

B.They knew little about the newspaper business.

C.They often held conflicting opinions.

D.They kept a very tense relationship.

A.Summarize the previous paragraphs.B.Add some background information.

C.Introduce a new topic for discussion.D.Provide more examples to support his idea.

4What is the best title for the text?

A.Conversation matter in a family kidsB.Uncomfortable silence harms Kids.

C.Kids, would you please start fighting:D.Parents, would you please stop arguing?

【题目】 Internet firms should help deal with the threat of terrorism or face terror tax , the security minister has said. Ben Wallace said such profiteers as Facebook and Google were failing to play their part, forcing the government to spend hundreds of millions to police internet extremism. The minister added, “If they continue to be less than co-operative, we should look at things like tax as a way compensating for their inaction. Because content is not taken down as quickly as they could do, we have to spend millions. WhatsApp, owned by Facebook, was turning the internet into a violent space.”

Mr Wallace did not give more details about a possible terror tax, but it would probably take the form of a windfall tax. The minister also accused internet companies of putting profit before public safety.

Simon Milner, Facebook’s UK policy director, said: “Mr Wallace is wrong to say that we put profit before safety, especially in the fight against terrorism. We’ve invested millions of pounds in people and technology to identify and remove terrorist content.” YouTube, which is owned by Alphabet, Google’s parent company, said: “Violent extremism is a complex problem and addressing it is a critical challenge for us all. We are committed to being part of the solution and we are doing more every day to deal with these issues. “Over the course of 2017 we have made significant progress through investing in machine learning technology, recruiting more reviewers, building partnerships with experts and collaboration with other companies”.

Anthony Glees, an intelligence expert at Buckingham University, told The Times: “What the government is proposing makes excellent theoretical sense when it comes to making us more secure from the appalling things that are broadcast by the service providers.” He added: “But in practice it may not be enough, because we are dealing with Goliaths here and the United Kingdom is increasingly becoming a lone David.”

1What do we know from Ben Wallace’s words?

A.The internet firms have been put on a terror tax.

B.The internet companies only concentrate on profit.

C.The profit of the Internet firms should be cut down.

D.The internet companies are not cooperative enough.

2What did “they” in the first paragraph refer to?

A.internet firmsB.internet extremism

C.violent spacesD.terror taxes

3Anthony Glees thought the government’s behavior was ______.

A.unpracticalB.positive

C.unexpectedD.disapproving

4What’s the best title of the passage?

A.Profit or Safety?

B.Policing Internet Extremism.

C.Internet Giants Threatened with Tax.

D.Demonstrating the Government’ Determination.

【题目】 It was just a normal day for Ruth Miller, a 63-year-old woman until everything went horribly wrong. She was walking to her car after shopping when the unthinkable happened.

Right as she was unlocking her car, a man quickly came up behind her and tried to wrestle her purse away. She was in shock. Luckily she remembered she had her Safe Personal Alarm (SPA) on her purse, and since she was too scared to scream for help, she quickly reached for the alarm and pulled the pin (保险栓). Immediately her SPA started just screaming. The man didn't know what to do! He froze for a second, and then ran away like a bat out of hell!

SPA is a safety device capable of creating a 125db sound that attracts attention and scares away potential attackers. To compare, it's the same volume as a military jet during takeoff.

Paul Davidson, the inventor of SPA, knows all too well the type of situation that Ruth found herself in. But that's not the only type of situation that SPA helps protect against. Parents can give it to their kids as an extra means of protection. Teenagers can use it so they can feel safe walking home. Women can know it's there when they have to use the parking lot at night. “My mother, who is 76 years old, carries it around in case she falls and needs to ask people for help. I only wish I'd have thought of it earlier,” said Paul.

The police have been recommending SPA since it first hit the market. In fact, since its launch, SPA has been in a state, shifting between in stock to sold out nearly every other week, and it's also got tons of loyal followers worldwide.

1What does the underlined part “the unthinkable” in Paragraph 1 refer to?

A.An attempted robbery.B.A wrestling match.

C.An angry argument.D.A car accident.

2How did Ruth react to the unexpected situation?

A.She fought violently.B.She froze in great fear.

C.She cried desperately for help.D.She sounded her safety device.

3Why does Paul mention his mother?

A.To imply the elderly need more care.B.To suggest he cares about his mother.

C.To show SPA can be widely used.D.To make an advertisement for SPA.

4What can be learned from the text?

A.SPA is well received in the market.B.People hesitate to pay for security.

C.SPA was sold out in the first two weeks.D.SPA is not important in life.
