How Smartphone Adds to Your Weight
Using a smartphone at mealtimes can lead to an expanding waistline. Researchers have found that men and women consumed 15% more calories when looking at their phones while eating. 1. The groundbreaking study suggests that staring at a phone screen may distract (分心) dinners from how much food and what they are actually eating.
“It may prevent the correct understanding of the brain over the amount of food ingested,” said researchers who filmed 62 volunteers eating alone.
The volunteers, aged 18 to 28, were divided in to three groups and invited to help themselves to a choice of food — ranging from healthy options to soft drinks and chocolate — until they were satisfied. 2. On average, the volunteers ate 535 calories without the distraction of a smartphone but 591 when using a mobile. Those in the sample who were classed as overweight ate 616 calories while using their phones. When in possession of their mobiles, the volunteers also consumed 10 percent more fatty foods. 3.
“Smartphone use during a meal increased calorie and fat intake,” said Márcio Gilberto Zangeronimoa, a lead author of the study — carried out at the Federal University of Lavras in Brazil and University Medical Center Utrecht in the Netherlands. He added: “Tablets and smartphones have become the main ‘distracters’ during meals, even early in childhood. 4.A distracter prevents the brain correctly understanding the amount of food accepted.”5. A more detailed analysis can be found in the journal.
A.They also eat more fatty food.
B.They also ate more when reading a magazine.
C.Distracted or hurried eating can add to weight gain.
D.The study is published in Physiology And Behavior.
E.It is important to pay attention to how this may impact food intakes.
F.Hunger isn’t the only thing that influences how much we eat during the day.
G.They were recorded eating with no distractions, using a smartphone or reading a magazine.

Imagine that you’re looking at your company-issued smartphone and you notice an e-mail from Linkedln:“These companies are looking for candidate like you!” You aren’t necessarily searching for a job, but you’re always open to opportunities, so out of curiosity, you click on the link. A few minutes later your boss appears at your desk. “We’ve noticed that you’re spending more time on Linkedln lately, so I wanted to talk with you about your career and whether you’re happy here,” she says Uh-oh.
It’s an awkward scene. Attrition(损耗) has always been expensive for companies, but in many industries the cost of losing good workers is rising, owing to tight labor markets. Thus companies are making greater efforts to predict which workers are at high risk of leaving so that managers can try to stop them. Methods range from electronic monitor to sophisticated analyses of employees’ social media lives.
Some of this work may be a reason to let employees to quit. In general, people leave their jobs because they don’t like their boss, don’t see opportunities for promotion or growth, or are offered a higher pay; these reasons have held steady for years.
New research conducted by CEB, a Washington-based technology company, looks not just at why workers quit but also at when. “We’ve learned that what really affects people is their sense of how they’re doing compared with other people in their peer group, or with where they thought they would be at a certain point in life, says Brian Kropp, who heads CEB’s HR practice. “We’ve learned to focus on moments that allow people to make these comparisons.”
Technology also provides clues about which star employees might be eyeing the exit. Companies can tell whether employees using work computers or phones are spending time on (or even just opening e-mails from) career websites, and research shows that more firms are paying attention to these things. Large companies have also begun tracking badge swipes(浏览痕迹)—employees’ use of an ID to enter and exit the building or the parking garage—to identify patterns that suggest a worker may be interviewing for a job.
1.From the first paragraph, we can infer Linkedln is ________.
A. an e-mail
B. a job from the Internet
C. a professional social network
D. a world-famous company
2.What’s the main idea of the second paragraph?
A. The cost of losing good workers is rising.
B. Companies are stricter with workers than before.
C. Measures have been taken to find the potential workers who want to quit.
D. Finding new jobs has been a trend for most workers.
3.According to the research by CEB, which of the following might be the most probable reason for workers to quit their jobs?
A. They don’t like their bosses.
B. Workers are always doing comparisons.
C. Not seeing opportunities for promotion.
D. To find a higher-paid job.

One day your pocket might power your smartphone． Soon you may never have to worry about your smartphone running out of juice． Your clothing will simply power it back up for you． That's the word from scientists at China's Chongqing and Jinan Universities in a study just published in the journal ACS Nano．
Researchers have been hard at work during the last few years trying to create wearable energy， or clothes that can charge things． The assumption is simple． People today rely heavily upon devices such as smartphones and tablets． And they're looking for ways to recharge these devices on the go． So if you could design clothing fabric that could make use of solar power -one of the most widely available and inexhaustible renewable energy sources - you'd be able to charge your various devices with ease．
Scientists have had some past success creating energy-harvesting fibers． But there was always one problem when they tried to fashion these threads into self-powered smart clothes： The fibers they designed got damaged during the clothing manufacturing process， namely during the weaving and cutting． The Chongqing and Jinan University scientists say they've solved this problem because the energy-collecting and energy-storing threads they created are highly flexible - each individual thread is easily bendable， and not simply the fabric as a whole．
The team's sample textile can be fully charged to 1.2 volts in 17 seconds by exposure to sunlight - enough voltage that your future smart T-shirt or smart dress might be able to power small electronics． It's durable， too； their research showed there was no descent in the fabric after 60 days． But don't worry that this means the fabric is similar to rough cloth． The scientists note their textile can be fashioned into numerous different patterns， and tailored into any designed shape， without affecting performance．
1.What does the underlined phrase "running out of juice" in Paragraph 1 mean？ ______
A. Being lacking in energy． B. Wanting to have some juice．
C. Being picked out of a drink． D. Having some water running out．
2.Why could smart dress charge a phone？ ______
A. A solar cell is attached to the dress．
B. The fabric of the textile contains current．
C. The fabric of the textile is easily bendable．
D. The fabric of the textile could collect and store the solar energy．
3.What is the scientists' attitude towards the scientific technology？ ______
A. Optimistic． B. Pessimistic．
C. Neutral． D. Doubtful．
4.This passage is written to ______ ．
A. persuade readers to buy new clothes
B. inform readers of the ways to use their devices
C. introduce new wearable energy to readers
D. remind readers to wear smart clothes

Have you ever noticed that after about 6 months your perfectly new 1，000 dollar smartphone begins to slow down? What if I told you that it’s a sales strategy that pretty much all phone companies use to force people into buying new phones?
In late 2015，when Lisa Young was in charge of iOS security and beta software testing teams，her boss revealed a dark secret to her，saying that they were using a new strategy that would purposely slow down older phones every time the phone would upgrade to the latest opera ting system. This new method would force customers to buy the latest phone model，increasing sales by 70％.
She was a little disturbed to hear the news，but she just kept her head down and continued to do her job. After a while，the guilt of being involved with such a shady sales model started to weigh heavy on her. “How could a multi—billion dollar corporation continue to take advantage of the public like this?” she thought. In March of 2017，she contacted a reporter from CNN to finally leak the information concerning Apple slowing down phones.
The scandal(丑闻)went viral overnight，and every media outlet in the world，in every language was talking about it，making it one of the biggest controversies in consumer electronics history. A week later，she was secretly let go after her 8 years of service. Although she was taking a huge risk going against one of the most powerful corporations in the world，she felt a sense of relief exposing them. The public deserved to know and the fear became her motivation to find a way to destroy their shady sales model.
Several of her colleagues were fired with her. They quietly united，and after a year of extensive research they designed a unique product called Circa Charge that would reverse the negative effects of “software updates.” Phone companies have recently caught wind of their overnight success with CircaCharge and are trying to do everything they can to make this product illegal and ban it forever. Lisa and her team have ma de unbelievable progress in increasing battery life，battery health，and optimizing phone performance，and they will continue to develop new technology that will beat phone companies at their own game until they change their ways.
1.What can we learn about the new method mentioned in paragraph 2?
A. It is essential in the 1atest operating system.
B. It benefits users in upgrading their old phone.
C. It fool s customers into buying the latest model on purpose.
D. It is a successful sales strategy for advertising new soft wares.
2.What does the underlined phrase “kept her head down” in paragraph 3 refer to?
A. Lowered her head.
B. Nodded to show approval.
C. Pretended to know something.
D. Tried not to show she knows something.
3.How did Lisa Young feel after leaking the secret?
A. Disturbed. B. Relieved. C. Frightened. D. Disappointed.
4.From the passage，we know______________.
A. it's too tough for Lisa and her team to increase battery life
B. CircaCharge helps phone companies with software updates
C. Lisa struggles to force phone companies to change their current ways
D. phone companies find it essential to ban their illegal software for updating

While there are a few ways to make use of your old smartphone, one of the better ways is to convert into a dash cam (行车记录仪) that you can use on your bicycle. With the camera, you can record your rides, which is especially helpful if you are involved in a crash with another vehicle.
To use your smartphone as a dash cam on your bike, you will need to make sure it is properly secured to your bike. To do this correctly, you must take two strips of heavy-duty Velcro (a kind of cloth used as fastening) along with two pipe Clamps (管夹) and a flat corner brace (角撑) to properly attach it. You will start by attaching the comer brace to your smartphone.
Next, attach a Velcro strip to your phoned back. You will put the second strip on the end of the brace comer and cut any extra Velcro off and away from the brace. By using heavy-duty Velcro, you shouldn’t have to worry about the camera brace must be attached to the bicycle directly.
Take two pipe clamps so you can attach the part of the corner brace so the phone can be held up and used. The pipe clamps must be positioned near the center of the handlebar, which will enable you to get a better picture when videotaping.
To run a dash cam app on your old phone, you will just need to download a dash cam app onto the old phone. You will then just start the app at any time you head out on the road. There is always the chance of flaws, but you will be giving yourself a way to protect yourself in a friendly, eco-friendly manner that is much less expensive than purchasing a dash cam.
1.What is the purpose of building a dash cam on your bike?
A. To make full use of an old smartphone.
B. To record the scenery while travelling.
C. To reduce an unexpected crash on the road.
D. To avoid unnecessary arguments in an accident.
2.What does the underlined word “it” in Paragraph 2 refer to?
A. The bike. B. The pipe clamp.
C. The smartphone. D. The flat comer brace.
3.What can we learn about a Velcro strip?
A. It will fix the camera firmly.
B. It is better to keep it as long as possible.
C. It is important for the flat comer brace.
D. It is best put in the center of the smartphone.
4.What can be inferred about the DIY dash cam from the last paragraph?
A. It is a perfect alternative to a purchased one.
B. It is beneficial to environment in some way.
C. It is a much more demanding job for the user.
D. It makes its owner friendly to other people.

Operating system． 2. In general，a smartphone will be based on an operating system that allows it to run applications．For example，Apple’s iPhone runs the iOS，and BlackBerry smartphones run the BlackBerry OS．
Mobile Internet． 3. For this we should say thanks to the growth of 4G data networks，as well as the addition of Wi-Fi．
4. A smartphone may allow you to download apps，edit photos，and get driving directions with GPS．The applications may also allow you to create and edit Microsoft Office documents—or at least view the files．
QWERTY Keyboard．A smartphone includes a QWERTY keyboard．This means that the keys are laid out in the same manner they would be on your computer keyboard，where you don’t have to tap the number 1 to enter an A，B or C．
These are just some of the features that make a smartphone smart．5. What makes a smartphone today may change by next week，next month or next year．Well，a smartphone of the future may be in your brain．
A．Apps．
B．Documents．
C．In the beginning，there were cell phones and PDAs．
D．A smartphone is a mobile phone with an operating system．

Using a computer or smartphone at night can cause us to pile on the pounds，new research has revealed．
The study found a link between blue light exposure(blue light is produced by smartphones and computers)and increased hunger．It found that exposure to blue light increases hunger levels for several hours and even increases hunger levels after eating a meal．Blue light exposure has also already been shown to cause decreased sleepiness in the evening，increasing the risk of sleeplessness．
The leading researcher，Ivy Cheung，from Northwestern University in Chicago，said，“A single three-hour exposure to blue-enriched light in the evening greatly affected hunger and metabolism(新陈代谢)．These results are important because they suggest that controlling environmental light exposure for humans may represent a novel approach of influencing food intake patterns and metabolism．”
The study group consisted of 10 healthy adults with regular sleep and eating schedules. They completed a four-day trial under dim(昏暗的)light conditions，which involved exposure to less than 20 lux(勒克斯，照明单位)during 16 hours awake and less than 3 lux during eight hours of sleep．On the third day they were exposed to three hours of 260 lux，blue-enriched light starting10.5 hours after waking up．and the effects were compared with dim light exposure.
Ivy Cheung said more research is needed to determine the functions involved in the relationship between light exposure，hunger and metabolism．
1.What is Paragraph 2 mainly about?
A．How blue light exposure affects hunger．
B．Why blue light exposure influences sleepiness．
C．What is the link between blue light exposure，hunger and sleepiness．
D．Who has found the effects of blue light exposure on hunger and sleepiness．
2.The underlined word“novel”in the third paragraph probably means“___________”.
A．unusual B．unforgettable
C．temporary D．controversial
3.What can we learn from the passage?
A．Blue light exposure can make us lose weight at night．
B．Blue light exposure has no effect on sleeplessness．
C．The researchers drew their conclusion by comparison．
D．Ivy Cheung has found the relationship between light exposure and hunger．
4.Where would you be most likely to find the passage?
