Could the device, smartphone or PC, which you re using affect the moral decisions you make when using it? To test it, researchers presented multiple dilemmas to a sample set of 1,010 people. The participants were assigned a device at random.
One case of the questions participants were asked is the classic “trolley(有轨电车) problem”: A runaway trolley is headed towards five people tied up on a-set of train tracks. You can do nothing, resulting in the deaths of five people, or push a man off a bridge, which will stop the trolley. The practical response is to kill one man to save five lives, which 33. 5 percent of smartphone users chose, compared to 22.3 percent of PC users.
“What we round in our study is that when people used a smartphone to view classic moral problems, they were more likely to make more unemotional, reasonable decisions when presented with a highly emotional dilemma, “Dr Albert Barque-Duran, the lead author of the study, told City, University of London. “This could be due to the increased time pressure often present with smartphones and also the increased psychological distance which can occur when we use such devices compared to PCs.”
As for why the researchers started this study, Dr Barque-Duran noted, “Due to the fact that our social lives, work and even shopping take place online, it is important to think about how the contexts where we typically face moral decisions and are asked to engage in moral behavior have changed, and the impact this could have on the hundreds of millions of people who use such devices daily. “it’s clear that we need more research on how our devices affect our moral decision making because we’re using screens at an ever increasing rate.

A. To introduce a difficult problem to readers.
B. To introduce the aim of carrying out the study.

D. To show the difficulty in dealing with dilemmas.
2.How do the smartphone users of the study behave in dealing with emotional dilemmas?

Whether you use a GPS device（设备） in your car or Google Maps on your smartphone, few of us travel anymore without digital help. 1. For one thing, GPS isn’t as accurate as you might think. What’s more, science is beginning to discover that people who rely only on navigational technologies may have a poor sense of place during travel.
2. They soon become outdated as cities change, requiring users to continually purchase updated versions. They’re also easily damaged from exposure to water, poor weather conditions and other physical forces.
However, paper maps still offer a few advantages that technologies can’t. For example, studying a map allows you to get a full view of where you’re going, including the roads, forests, towns, historic sites, rivers and mountains you’ll come across along the way. Many older maps are wonderful, offering a lovely feast for the eyes. 3.
Research by Toru Ishikawa and colleagues at the University of Tokyo found that GPS users spent 30％ more time looking at their device than those who used a paper map. 4. Instead they tended to stare at their screens and follow directions, never gaining a full view of where they were going.
Therefore, go ahead and use your GPS, but also carry a paper map as a handy backup. 5. Also it could even be a life-saver!
A. It will improve your travel experiences.
B. But don’t hurry to fold up your paper maps.
C. They also had a poorer recollection of surrounding scenery.
D. Compared with digital maps, paper maps do have disadvantages.
E. What’s more, paper maps tend to focus on smaller geographic areas.
F. They can also take you back in time to have a glimpse（瞥） of history.
G. In other words, they didn’t see or experience much during their travels.
高三英语七选五中等难度题查看答案及解析
Which animal has the fastest snapping jaw (颚)? If you're guessing a shark or perhaps a larger animal, you'll have to think smaller. The trapjaw ant, which lives in Central and South America, moves its mouth parts at 35 to 63 meters per second. Another way to think about this is that the ant's jaws close at 125 to 233 kilometers per hour. That's 2, 300 times faster than the blink of an eye.
Scientists were able to measure the amazing jaw speed using highspeed video techniques. Sheila Patek, a biologist, says the key is that the jaws have a springy (有弹性的) system, which is critical in getting explosive (爆发性的) speeds.
Consider a bow and arrow. If you try to throw an arrow with your arm, it won't go very far. If you use a bow, elastic energy stored in the bow is released almost instantly when you release the arrow with your finger or a latch. The combination of the springy bow and latch mechanism is what makes the arrow zoom through the air.
Maybe even more amazing than how fast these ants grab food or even enemies is how they use this same energy to move. As the ant closes its jaws, it uses them to push off the ground—all faster than the eye can see without slow motion video. A snap of the jaw can send an ant up to 8.3 centimeters into the air. That's like someone who is 1.7 meters jumping 13 meters high! Not only can they quickly escape from enemies, but often a group of ants will start jumping all at once. It would be hard for their enemies to grab just one.
People have suspected the ants used their jaws to jump for over a century, but could only prove it with today's modern video equipment.
1.The fast speed of the trapjaw ant's jaw lies in ________.
| A．its light body |
| B．its springy system |
| C．its living environment |
| D．the length of its jaw |
2.The passage uses “a bow and arrow” as an example to show ________.
| A．how an arrow gets so much energy to fly |
| B．why the trapjaw ants have springy system |
| C．why the trapjaw ants jaws move so fast |
| D．how a bow and arrow works |
3.Which of the following may amaze the scientists most?
| A．How high the ants can leap by using their jaws. |
| B．How quickly the trapjaw ants can move on the ground. |
| C．How wonderfully the springy system in the trapjaw ants' jaws works. |
| D．How quickly the trapjaw ants can grab food or enemies. |
4.According to the passage, the trapjaw ants' jaws keep them safe because ________.
| A．they can catch their enemies easily with their jaws |
| B．their jaws make them difficult to recognize |
| C．their jaws help them find food easily |
| D．their jaws help them escape from their enemies |

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?
A．On a notice board． B．In a health magazine．
C．On a business website． D．In a college newspaper．

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.
