【題目】Don’t push yourself too hard. Sometimes even the most careful person __________ make a mistake.

A.mustB.canC.shouldD.need

【答案】B

【解析】

句意:別把自己逼得太緊。有時(shí)候即使是最細(xì)心的人也會犯錯。

考查情態(tài)動詞。A. must一定;B. can可能;C. should理應(yīng)、想必;D. need需要。此處應(yīng)用情態(tài)動詞表推測,D選項(xiàng)可排除。should通常是指非?赡艿氖,must表示較有把握的推測,can相比前兩者則把握不大,只是可能。根據(jù)句意可知,此處指的是最細(xì)心的人也可能會犯錯,can最為符合語境,故選B。

【題目】 When we were kids, learning polite expressions was important. Our parents taught us to say “thank you” when we received help, and to say “please” when we needed a favor from others. But would you say “thank you” and “please” to a digital (數(shù)碼的) assistant?

Recently, Amazon announced it had added new features (特點(diǎn)) to its smart assistant Alexa. One of the developments—a politeness feature—draws some parents’ attention. Their children keep forgetting their manners because they have become used to shouting orders at their Echo, a smart speaker similar to Alexa.

When kids ask Alexa to solve a math problem using the word “please” as in “Alexa, please tell me what 5 plus 7 is” —Alexa will not only give the correct answer, but also give the following response “Thanks for asking so nicely”.

However, some people believe kids shouldn’t have to thank a machine, as children can tell the difference between machines and humans. But then again, we don’t usually talk aloud to a fridge or an ATM, either.

“I ask Siri to turn on the lights or set an alarm in the same natural language that I use in day-to-day life,” commentator (評論員) Chaim Gartenberg wrote on the website. “It doesn’t matter that an Echo can’t hear or understand it—it matters that you say it.”

With the increasing use of AI (artificial intelligence), forming the habit of being polite in everyday life is becoming even more important, as the British research company ChildWise found. In January, it published a report warning that people who become used to cutting courtesies (禮貌話) and giving orders to digital assistants might become rude when dealing with others.

Traditionally, we can tell how nice people are by watching how they interact with a waiter. In a similar way, even if the AI or digital assistant doesn’t care about it, other people around us are going to experience how we interact with it.

根據(jù)材料內(nèi)容選擇最佳答案。

1According to paragraphs 2 and 3, what’s true about the new Alexa?

A.It only follows children’s orders.B.A new speaker Echo is added to it.

C.It can help children learn good manners.D.It will refuse to answer if it’s treated rudely.

2What’s the problem with some children nowadays?

A.They keep shouting orders at their parents.

B.They forget their manners when talking to a smart assistant.

C.They can’t solve simple math problems.

D.They can’t tell the difference between machines and human.

3What does Chaim Gartenberg probably think of the politeness feature in Alexa?

A.It’s unsafe.B.It’s popular.C.It’s inconvenient.D.It’s helpful.

4What did ChildWise find about people who treat machines badly?

A.They become less important.B.They take more interest in giving orders.

C.They might be rude to people.D.They don’t know how to deal with others.

5What’s the text mainly about?

A.New features of Amazon’s smart assistant Alexa.B.Why it’s important to be polite to machines.

C.Problems caused by the increasing use of AI.D.How AI influences people’s manners.

【題目】 Trust is a learned behavior that we gain from past experiences. 1 Trust is a risk. But you can’t be successful when there isn’t enough trust in a relationship.

Unfortunately, we’re all been victims(受害者) of betrayal(背叛). Whether we’ve been lied to, misled, or cheated on, there are different levels of losing trust. Sometimes people’s simply can’t trust anymore. 2 It’s easy to understand, but if you’re willing to build trust in a relationship again, we have some steps you can take to get you there.

3 Having confidence in yourself will help you make better choices because you can see what the best result would be for your health and happiness.

4 If you’ve been betrayed, you are the victim of your situation. But there’s a difference between being a victim and living with a “victim mentality(心態(tài))”. At some point in all of our lives, we’ll have our trust tested.

You didn’t lose “everything”. Once trust is lost, what is left? Instead of looking at the situation from this hopeless side, look at everything you still have and be thankful for all of the good in your life. 5 Instead, it’s a healthy way to work through the experience to allow room for positive growth and forgiveness.

根據(jù)材料內(nèi)容,從下面五個(gè)選項(xiàng)中選出能填入文中空缺處的最佳選項(xiàng),使短文意思通順,內(nèi)容完整。

A.Learn to really trust yourself.

B.It is putting confidence in someone.

C.Stop regarding yourself as the victim.

D.That’s because they’ve been too badly hurt and they can’t bear to let it happen again.

E.Seeing the positive side of things doesn’t mean you aren’t paying attention to what happened.

【題目】 Is there anything that you do to cheer yourself up and “heal(治愈)” your mind when you’re feeling down? Many of us have our own ways to make ourselves feel better. This is referred to as “self-care”.

This idea originated(起源) in Japan. It refers to any activity that can soothe one’s nerves(平緩心緒), clear one’s mind, and comfort a troubled heart, according to China News Service. It was first used to describe the music of Japanese songwriter Ryuichi Sakamoto(坂本龍一)in 1999.

Self-care is now booming(急速發(fā)展)in China as well. One of the most popular activities is “healing travel”. According to Caissa Touristic, a Beijing-based travel agency, more Chinese tourists are going on meditation(冥想)or yoga retreats in places like Japan, Bali and India.

By taking these trips, people can learn more about local culture and the way people in these countries live. Without a tour guide or detailed plan, they allow their bodies and minds to relax as they forget about daily stresses and noisy surroundings(周遭事物)back home.

Having a pet can also help to improve our mental health. Research has shown that pets and humans can heal each other, NPR reported. Strong human-to-animal bonds(情感聯(lián)系)make both pets and their owners happier and healthier. Chinese dog and cat owners spent over 5,000 yuan per pet on average in 2018. China’s pet industry now has a value of over 170 billion yuan, Xinhua reported.

More people are seeking out self-care activities simply because they can finally afford to, particularly China’s growing middleclass(中產(chǎn)階級). With fewer financial(財(cái)務(wù)的)worries, they can slow down and take a closer look at their own inner(內(nèi)心的)world, the Paper noted.

1What do we know about “self-care” in the story?

A.It means living by yourself.B.It started in Japan about 20 years ago.

C.It focuses on one’s physical health.D.It refers to activities done by yourself.

2People may feel “healed” while going on trips because _________.

A.they can do meditation or yoga during their tripsB.they get to know how other people live

C.they can relax and avoid daily stressD.they don’t need to make plans

3According to Xinhua, which of the following is TRUE?

A.“Healing travel” is a popular “self-care” activity.

B.Pets can’t help their owners stay healthy mentally.

C.Chinese people prefer to raise cats.

D.Chinese pet owners spend a lot of money on their pets.

4What can we infer from the story?

A.Ryuichi Sakamoto’s music can make people feel better.

B.People who have pets are not necessarily happier or healthier.

C.The middle class experiences more stress and mental health problems.

D.Chinese people will spend more money on their pets.

5What’s the best title of this passage?

A.How to Keep PetsB.How to Live Longer
