Smartwatches and fitness trackers (健身追踪器)have gained popularity recently. These tools can record your daily steps, heart rates, etc. 1.. If yes, it might be a sign that you’re addicted to your fitness tracker.

2.. If you keep setting unrealistic daily goals that involve working out for too long, and if you begin to ignore friends and responsibilities to make time for your workout, then you’re most probably addicted to your fitness tracker.

It’s a struggle to overcome the addiction to fitnesstrackers. 3.. For example, the number in your smart watch showing how far you’ve come can give you a sense of achievement.

Of course, failing to meet your daily goal can be discouraging. You might focus on your shortcomings rather than your progress. Another problem is that you might find yourself paying too much attention to the step number rather than how your body feels. 4..

Therefore, if you’re spending too much time looking at your smartwatch, limit your daily step count to a comfortable level. 5.. For example, concentrating on your hobbies or socializing with friends can be a great way to keep your mind on other things.

A.Don’t overuse your smartwatch.

B.It doesn’t convey what you’re really feeling.

C.After all, reaching a daily step count can be so appealing.

D.How can you tell whether you’re addicted to your fitness tracker?

F.However, do you find yourself checking your steps and heart rates too often?

G.Besides, you can find other things to do that don’t involve checking your fitness tracker.

Though not as mainstream as devices like smartphones and fitness trackers, more companies are now experimenting with the concept of connected garments. Among the pioneers is London-based CuteCircuit, which has been creating fashionable smart clothing since 2004. The company’s latest creation is the “Sound Shirt,” which allows deaf people to “feel” live music by transforming the tunes into touch sensations in real time.

The fashionable jacket achieves the incredible function using software that changes the music into data and wirelessly sends it to the 16-micro motors fitted inside the clothing’s fabric. The devices shake in sync (同步) to the intensity (强度) of the music being played, allowing the wearer to feel each instrument individually. The series of touch-like sensations across the wearer’s body enables them to feel the entire works, resulting in a fully amazing musical experience.

To ensure the shirt is comfortable, the designers chose to leave out wires and instead wove conductive textiles (纺织品) into the garment’s fabric. Francesca Rosella, co-founder and chief creative officer of CuteCircuit, explains, “There are no wires inside, so we’re only using smart fabrics — we have a combination of microelectronics and very thin, flexible and conductive fabrics. All these little electronic motors are connected with these conductive fabrics so that the garment is soft and stretchable.”

CuteCircuit, which has been testing the Sound Shirt for three years, expects to make it available to the general public shortly. Priced at $3,673 (3,000 pounds), the smart jacket will not be cheap. However, twin sisters Hermon and Heroda Berhane, who lost their hearing at a young age, believe the hi-tech garment is a worthwhile investment, especially for deaf people with a passion for dancing. “It’s almost like feeling the depth of the music,” says Hermon. “It just feels as though we can move along with it.” Heroda agrees, adding, “I think it could definitely change our lives.”

This is not CuteCircuit’s first groundbreaking smart garment. Over the years, the company has produced hundreds of shocking connected outfits. Among them is an interactive concert dress for American musical artist Nicole Scherzinger that displayed tweets from her fans. Also fun is the HugShirt which enables people to send hugs to loved ones who are not physically in the same area.

1.What is “sound shirt” meant for?

A.Children. B.Students.

2.Paragraph 2 mainly talks about the sound shirt’s_____________.

A.working principle B.powerful function

3.How did the designers keep the shirt comfortable?

A.To persuade us to learn from them.

B.To get the public to know them better.

5.The function of the last Paragraph is to ______________.

Apps from Chinese developers have been gaining popularity on Indian app stores for some time. In 2018, as many as 44 of the top 100 Android apps in India were developed by Chinese firms.

But things changed last year as local developers put on a fight. According to app analytics and marketing firm AppsFlyer, Indian apps as a whole have recaptured their original standing.

Indeed, 41% of the top 200 apps in Indian editions of Googl's Play Store and Apple's App Store in the second and third quarters of last year were developed by Indian developers and local firms, up from 38% in 2018, the report said. Data from App Annie, another research firm, corroborates (证实) the claim.

"This uptick happened mainly at the expense of Chinese apps, which fell from their lead position to 38% from 43% in 2018. Altogether, Chinese and Indian apps make up almost four-fifths (79%) of the list," the report said.

The change comes as scores of Indian firms have launched payments, gaming, news and entertainment apps in the last year and a half, said AppsFlyer, which analyzed 6.5 billion installs (安装)in the second and third quarters of last year.

But Chinese developers are not giving up, and continue to keep an "impressive" fight in each category, the report said.

India, which is home to more than 450 million smartphone users and keep relatively loose laws to support an open market, has naturally appeared as an attractive battleground for developers worldwide.

Many Chinese firms, including Xiaomi and ByteDance, regard India as one of their largest markets. Tik Tokapp has amassed(积累) more than 200 million users in India, for instance. Xiaoni, which leads the Indian smartphone market, is quickly building a series of services for users in India.

It launched a lending app the in country earlier in November 2018.

1.Because Indian firms launched varieties of apps in 2019__________.

A. Chinese apps lost their lead position.

B.Chinese developers gave up their competition.

C.India apps make up most of the top 200.

D.the percentage of Chinese apps went down sharply.

2.The underlined word uptick in the 4th paragraph most probably means__________

A.Sharp decrease. B.slight increase

C.a little fall D.statistical data

3.Many Chinese developers compete for Indian markets for all the following reasons except_________

A.huge market need.

B.laws in favor of foreign firms.

C.a market system open to the world

D.absolutely fierce competition.

4.What attitude did the author hold when analyzing the market situation?

A.Critical B.Confused

C.Subjective D.Objective

The organic food has gained a lot of [popularity as they are being considered as healthier and tastier.　 A fair number of people advocate a large-scale shift to organic farming from conventional agriculture. But this might not seem well-founded.

Since the mid-19th century, conventional industrial agriculture has become incredibly efficient on a simple land to food basis. Conventional farming gets more and more crop per square foot of land, which can mean less wilderness needs to be transformed to farmland.

To make farming more efficient, conventional agriculture uses a significant amount of synthetic fertilizer（合成肥料）each year, and all that nitrogen（氮）enables much faster plant growth. However, the cost is paid in vast polluted dead zones at the months of many of the world’s rivers, because much of the nitrogen ends up running off the soil and into the oceans. This also makes conventional farming one of the major threats to the environment.

To weaken the environmental impact of agriculture, improve soil quality as well as produce healthier foods, some farmers have turned to organic farming. Environmentalists have also welcomed organic food as better for the planet than the food produced by agricultural corporations. Organic practices --- refusing artificial fertilizers and chemical pesticides –are considered far more sustainable. Sales of organic food rose 7.7% in 2010, up to $26.7 billion—and people are making those purchases for their moral senses as much as their tongues.

Yet a new meta-analysis in Nature does the math and comes to a hard conclusion: organic farming produces 25% fewer crops on average than conventional agriculture.

In the Nature analysis, scientists performed an analysis of 66 studies comparing conventional and organic methods across 34 different crop species, from fruits to grains. They found that organic farming delivered a lower output for every crop type, though the difference varied widely. For crops like fruit trees, organic trailed（落后于）conventional agriculture by just 5%. Yet for major grain crops and vegetables – all of which provide the world’s main calories – conventional agriculture outperformed organics by more than 25%.

What that means is that while organic farming may be more sustainable than conventional agriculture, there are trade-offs（此消彼长）with each. So an ideal global agriculture system may borrow the best from both systems rather than upholding merely organic or conventional practices.

1.What’s the author’s purpose of writing the passage?

A. To compare two types of farming.

B. To criticize conventional agriculture.

C. To discuss the development of farming.

D. To argue for a realistic agriculture system.

2.What do we know about conventional farming?

A. It produces more crops with fewer fertilizers.

B. It achieves efficiency at a huge cost to the environment.

C. If offers a long-term solution to global demand for food.

D. It performs far better for each crop type than organic farming.

3.What does the author most probably agree with?

A. Employing organic farming to plant rice.

B. Adopting organic practices to grow potato.

C. Using conventional methods to plant cabbage.

D. Applying conventional farming to growing apple.

4.Which of the following shows the development of ideas in this passage?

CP: Central Point　　 　　 P: Point　　 　　 Sp: Sub-point（次要点）　　 C: Conclusion

A. 　　 B.

Researchers have long known that lack of sleep can cause weight gain and increase other health risks. But for those who force themselves out of bed every weekday after too few hours of sleep, they always hope that turning off the alarm on weekends will repay the weekly sleep debt and change any ill effects around completely.

New research published in Current Biology destroys those hopes. Despite complete freedom to sleep in during a weekend recovery period, participants in a sleep laboratory who were limited to five hours of sleep on weekdays gained nearly three pounds over two weeks. They also experienced metabolic disruption (新陈代谢紊乱). Weekend recovery sleep had some benefits after a single week of lack of sleep. However, those gains were wiped out when people went back into their old schedule the next Monday.

“These health effects are long-term,” said Kenneth Wright at the University of Colorado at Boulder, who oversaw the work. “It’s kind of like smoking once was. People would smoke and wouldn’t see an immediate effect on their health, but now they will say that smoking is not a healthy lifestyle choice. I think “catch-up” sleep is in the early phase of where smoking used to be.”

Michael Grandner, at the University of Arizona, said the study highlights that people need to stop thinking of sleep as a balance sheet (资产负债表). Considerably cutting calories all week and then bingeing on (无节制地吃) a giant pizza on Saturday would not restore balance. That is essentially what people are doing when they skip sleep on weekdays with the idea that they can make up for it on the weekend.

The study suggests people should put sleep first — cutting out the optional “sleep stealers” such as watching television shows or spending time on electronic devices. Even when people do not have a choice about losing sleep due to tight schedules, they should think about sleep first in the same way they would a healthy diet or exercise.

1.Why do people hope to sleep longer on weekends?

A.To avoid some debt concerns. B.To cure some illness.

C.To get some health benefits. D.To get complete freedom.

2.What can we infer about weekend recovery sleep from Kenneth Wright?

A.It has the long-term benefits. B.It hides some potential harm.

C.It causes smoking problems. D.It contributes to losing weight.

3.What does the text suggest people do about sleep?

A.Sleep well every day. B.Guarantee weekly sleeping hours.

C.Make up for missing sleep. D.Stop watching TV shows before bed.

4.What can be a suitable title for the text?

A.Weekend “Catch-Up Sleep” Is a Lie.

B.Watch out for "Sleep Stealers".

C.Sleep and Smoking are alike.

D.Lack of Sleep Does No Good.
