【題目】 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 (新型冠狀病毒) 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.

【答案】

【1】F

【2】C

【3】B

【4】E

【5】G

【解析】

本文為說明文。文章敘述了手機(jī)上的細(xì)菌含量很高，但清潔手機(jī)要注意方法。

【1】考查對上下文的理解及推理判斷能力。根據(jù)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”如果你和普通美國人一樣，你可能會象2018年的一項研究發(fā)現(xiàn)的那樣，每天查看智能手機(jī)的次數(shù)可能會超過50次，手機(jī)攜帶的細(xì)菌是馬桶座圈的10倍�？芍�，每次這樣做，你的移動設(shè)備從你的手上收集更多的細(xì)菌。分析選項可知F項And each time you do, your mobile device picks up more bacteria from your hands（每次你這樣做，你的移動設(shè)備從你的手上收集更多的細(xì)菌）符合題意，故選F。

【2】考查對上下文的理解及推理判斷能力。根據(jù)上文“As the novel corona virus (新型冠狀病毒) 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.”隨著新型冠狀病毒繼續(xù)蔓延，美國疾病控制和預(yù)防中心和世界衛(wèi)生組織建議公眾經(jīng)常洗手，對經(jīng)常接觸的物體和表面進(jìn)行消毒�？芍�，保持手機(jī)清潔也很重要。分析選項可知C項That means keeping your phone clean is important as well（這意味著保持手機(jī)清潔也很重要）符合題意，故選C。

【3】考查對上下文的理解及推理判斷能力。根據(jù)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.” 考慮到許多你通常用來消毒的標(biāo)準(zhǔn)化清潔產(chǎn)品可能會損壞你的移動設(shè)備。你可能想用酒精或消毒劑擦拭一下手機(jī)屏幕。由此可知，如果用酒精或消毒劑給手機(jī)消毒的話會傷害手機(jī)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決方案在手機(jī)上、在杯子上使用會對身體造成傷害�？芍�，這樣會損壞你的設(shè)備屏幕。分析選項可知B項 But in doing so, you risk damaging your devices screen（但這樣做，你就有可能損壞你的設(shè)備屏幕）符合題意，故選B。

【4】考查對上下文的理解及推理判斷能力。根據(jù)上文“Using alcohol or those types of everyday solutions directly on a phone, on its glass can harm it.” 直接在手機(jī)上使用酒精或其他類似的日常解決方案會對手機(jī)造成傷害。所以要用超細(xì)纖維布，并用肥皂和水輕輕地潤濕。分析選項可知E項Instead use a micro fiber cloth and dampen it lightly with soap and water（取而代之的是使用一塊微纖維布，用肥皂和水輕輕地將其浸濕）符合題意，故選E。

【5】考查對上下文的理解及推理判斷能力。根據(jù)上文“That lines up with the advice Apple and Samsung offer which warn not to use cleaning products.” 這與蘋果和三星提出的警告不要使用清潔產(chǎn)品的建議一致。以及下文“If you need to disinfect your smartphone, consider looking into a UV light to kill the bacteria.”如果需要給你的智能手機(jī)消毒，考慮使用紫外線來殺死細(xì)菌。分析選項可知G項Both companies say wiping your phone down with a soft cloth is the best way to clean it（兩家公司都說用軟布擦拭手機(jī)是最好的清潔方法）符合題意，且G項中Both companies與文中所提的“Apple and Samsung”兩家公司是一致的，故選G。

【題目】 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.

【1】How did the author feel about the ride by a motor rickshaw?

A.Worthless.B.Courageous.

C.Common.D.Expensive.

【2】What does the underlined part mean in the passage?

A.The train ticket cost him too much.B.It was quite cheap to take the train.

C.The train was so convenient for him.D.It was unusual to take a train here.

【3】What do we know about the young man mentioned in the passage?

A.He wanted to learn to play tabla from the author.

B.He was a student on the way to a university.

C.He took his examinations seriously.

D.He wished to find a job in Tilak Nagar.

【4】What is the author's purpose of writing the passage?

A.To tell readers he got to know an Indian young man.

B.To imply it was unsafe to travel alone in India.

C.To complain the messy and dirty Indian train.

D.To share his first time on a train in India.

【題目】 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 (機(jī)械師) 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 (搖晃).”O(jiān)rville 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.

【1】What 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.

【2】What sort of father was Milton Wright?

A.Untraditional.B.Generous.

C.Scholarly.D.Sensitive.

【3】What does the author intend to do in Paragraph 3?

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.

【4】What 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?

【題目】 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.”

【1】What 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.

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

A.internet firmsB.internet extremism

C.violent spacesD.terror taxes

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

A.unpracticalB.positive

C.unexpectedD.disapproving

【4】What’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.

【題目】 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 (保險栓). 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.

【1】What 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.

【2】How 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.

【3】Why 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.

【4】What 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.
