Like many other people, I love my smart phone, which keeps me connected with the larger world that can go anywhere with me. I also love my laptop, because it holds all of my writing and thoughts. In spite of this love of technology, I know that there are times when I need to move away from these devices and truly communicate with others.
On occasion, I teach a course called History Matters for a group of higher education managers. My goals for the class include a full discussion of historical themes and ideas. Because I want students to thoroughly study the materials and exchange their ideas with each other in the classroom, I have a rule ---no laptop, iPads, phones, etc. When students were told my rule in advance of the class, some of them were not happy.
Most students assume that my reasons for this rule include unpleasant experiences in the past with students misusing technology. There's a bit of truth to that. Some students assume that I am anti-technology. There' s no truth in that at all. I love technology and try to keep up with it, so I carelate to my students.
The real reason why I ask students to leave technology at the door is that I think there are very few places in which we can have deep conversions and truly engage complex ideas. Interruptions by technology often break concentration and allow for too much dependence on outside information for ideas. I want students to dig deep within themselves for inspiration and ideas. I want them to push each other to think differently and make connections between the course materials and the class discussion.
I’ve been teaching my history class in this way for many years and the evaluations reflect students' satisfaction with the environment that I create. Students realize that with deep conversation and challenge, they learn at a level that helps them keep the course materials beyond the classroom.
I'm not saying that I won't ever change my mind about technology use in my history class, but until I hear a really good reason for the change, I'm sticking to my plan. A few hours of technology-free dialogue is just too sweet to give up.
1.Which of the following statements is true?
A. The author's history class received low assessment.
B. The students think highly of the author's history class.
C. The author made the rule in that he was against technology.
D. The author made the rule mainly because of his unpleasant experiences.
2.According to the author, the use of technology in the classroom may .
A. allow students to get on well with each other
B. improve teaching and offer more help
C. prohibit students being involved in class
D. help students to better understand complex themes
3.What can we infer from the passage?
A. More and more students will be absent in history class.
B. The author will carry on the success in the future
C. Some students will be punished according to the rule.
D. The author will help students concentrate on what they learn.

A new phone app uses vibrations from smart phones to warn people about earthquakes.
The phone app _______ sudden shaking of the earth’s surface through sensors in smart phones. It is called MyShake. It is the work of four researchers at the University of California, Berkeley. They said they created a worldwide warning system that would _______ people and give them time to prepare. The MyShake app is _______ only for Android phones.
Smart phones are _______ accelerometers (加速度感应器). These instruments measure movement, like that of a car or airplane. MyShake uses phone accelerometers to measure seismic (地震的) activity. It has been _______ to know the difference between normal activity and earthquake movement. The software developers say their app is right 93 percent of the time.
A smart phone sends seismic information to the app developers. If the developers receive several notifications _______, it recognizes that an earthquake might be taking place or will take place soon.
Using information sent from the app, the network then _______ the location and strength of the quake in real time. MyShake can record magnitude 5.0 earthquakes at distances of 10 kilometers or less.
MyShake uses very _______ power, according to its developers. Only when seismic activity is _______ by the app does it become active and sends data to the network. The app works best when your phone is resting on a ________ surface, like a table.
The developers hope that MyShake can add to information collected by the U.S. Geological Survey. That U.S. agency has created the Earthquake Early Warning System, also ________ EEW. The EEW has deployed (部署) sensors for measuring quakes in many areas.
In places where no such equipment ________, MyShake may be the only method of early quake ________. The app also shows ways to stay safer during an earthquake. The developers say it will become more effective as more people use it.
“Our goal is to build a worldwide seismic network and use the data to________ the effects of earthquakes on us as individuals and on society as a whole,” say the researchers.
The developers say they hope to add a feature that would ________ people about a possible tsunami: a huge wave after an earthquake.

As more people use smart phones to pay bills and store personal information, strict password security has become more important than ever. A new study shows that free-form gestures–sweeping fingers in shapes across the screen of a smart phone—can be used to unlock phones. These gestures are less likely to be observed and reproduced by others than traditional typed passwords.
“All that it takes to steal a password is a quick eye,” said one of the researchers of the study. “With all the personal information we have on our phones today, improving their security is becoming increasingly necessary.” In developing a secure solution to this problem, the researchers studied the practicality of using free-form gestures. With the ability to create any shape in any size and location on the screen, the gestures were popular as passwords. Since users create them without following a template, the researchers predicted these gestures would allow for greater complexity.
The researchers carried out a create-test-retest experiment where 63 people were asked to create a gesture, recall it, and recall it again 10 days later. The gestures were captured on a recognizer system designed by the team. Using this data, they tested the complexity and accuracy of each gesture using information theory. The result of their analysis is that people are favorable to use free-form gestures as passwords.
To put their analysis into practice, the researchers then had seven students in computer science and engineering, each with considerable experience with touchscreens（触摸屏）, attempt to steal a free-form gesture password by observing a phone user secretly. None of them were able to copy the gestures with enough accuracy. The gestures appear to be extremely powerful against attacks.
Though the testing is in its early stage and widespread adaptation of this technology is not yet clear, the research team plans to continue to analyze the security and management of free–form passwords in the future. They believe this is the first study to explore free-form gestures as passwords. They will soon publish their findings.
1.What can we learn about free-form gestures?
A. They are improving mobile security in a way.
B. Users will have to make use of simple gestures.
C. They will never be copied by others.
D. Users must move their fingers in fixed shapes.
2.The experiment in paragraph 4 is to test _________ of free - form gestures.
A. template B. application C. accuracy D. security
3.According to the text, the researchers think that ________.
A. it is easy to steal any password with a quick eye
B. better ways of setting passwords should be developed
C. people had better not use smart phones to pay bills
D. personal information should not be stored in a phone
4.The main purpose of the text is to ________.
A. advise people to use free-form gestures
B. discuss whether smart phones are safe
C. talk about the practicality of passwords
D. introduce the study of a new password

One in four children and young people could have problematic smart-phone use, according to research that also suggests such behaviour is associated with poorer mental health.
The amount of time children and teens spend using their devices has become an issue of growing concern, but experts say there is still little evidence as to whether spending time on screens is harmful in itself.
The experts behind the latest study said they wanted to look beyond the time young people were spending on smart-phones and instead explore the type of relationship they had with smart-phones.
The results suggest more than 23% of young people have an abnormal relationship with their smart-phones, and that this appears to be associated with poorer mental health-although the research cannot say whether phone use is driving such problems.
“It seems like only a minority of teenagers and young people from various different countries are self-reporting a pattern of behaviour that we recognise from other addictions,” said Dr Nicola Kalk of King’s College London, co-author of the study. “The quality of the evidence is poor, but it is enough to warrant (保证) further investigation.”
Writing in the journal BMC Psychiatry, the team reported how they looked at data from 41 studies involving a total of almost 42,000 participants across Europe, Asia and America, mainly in their teens or early 20s.
These studies used questionnaires to probe the prevalence (普遍) of problematic smart-phone use-behaviours such as being anxious when the device is not available or neglecting other activities to spend time on the smart-phone.
Taken together, the team said on average these studies suggested as many as one in four children and young people had problematic smart-phone use.
Among the studies that probed mental health, the results suggested people with problematic smart-phone use were also more likely to have depression-for which the odds (可能性) were more than three times worse-anxiety, feelings of stress and poor sleep as well as poorer educational attainment.
While the team said it was too soon to call problematic smart-phone usage an addiction, they noted that it appeared to be linked to similar patterns of behaviour and emotion.
Kalk said further studies were needed to explore if these behaviours were hard to break, or cause harm-other key features of an addiction.
The authors argued that the availability and pervasiveness of smart-phones in everyday life meant problematic use of the devices posed a different and much bigger public health problem than substances of abuse or internet gaming.
Kalk said the team were now looking at whether smart-phones were just delivering addictive content, or whether there was something inherently addictive about using such devices.
Dr Amy Orben, an expert in screen time at the University of Cambridge, raised concerns, noting that the definition of problematic internet use varied considerably across studies, and the measures used were questioned.
She said studies finding little signs of problematic internet use might have been overlooked, while the research could not say whether problematic smart-phone use caused poorer mental health.
Prof Russell Viner, President of Royal College of Paediatrics and Child Health, said that parents were navigating unchartered water when it came to technology.
“One of the most critical things for parents to consider is whether screen time is having a harmful impact on other activities like school, relationships or other interests. This study suggests that this is the case for a significant minority of children and young people,” he said.
Viner said in these cases parents should calmly install age-appropriate boundaries on smart-phone use, and ask questions about whether their children were experiencing other problems.
“While screen time is a new problem, part of the solution is tried and tested-open and regular conversations based on respect and trust,” he said.
1.Experts conducted the research to ______.
A.address the concern about adolescent behavior
B.prove spending time on screens is harmful in itself
C.calculate the time young people spent on smart-phones
D.explore young people’s relationship type with smart-phones
2.We can learn from the research that ______.
A.it involved a vast majority of participants across the globe
B.the participants were asked to report their online activities
C.researchers compared different behaviors of the participants
D.problematic smart-phone use is linked to poorer mental health
3.Which of the following might Kalk probably agree?
A.It is hard to break problematic smart-phone use.
B.Internet gaming is problematic smart-phone use.
C.Problematic smart-phone use is an addiction.
D.The research still has some limitations.
4.What’s Dr Amy Orben’s attitude towards the research findings?
A.Supportive. B.Negative.
C.Sceptical. D.Unconcerned.
5.What does the underlined part in Paragraph 16 mean?
A.Screen time is a new challenge to parents.
B.Technology is posing a threat to parents.
C.Parents are lost in the sea of technology.
D.Parents use technology to chart water.
6.According to Viner, what should parents do to solve the problem?
A.Keep track of the screen time of children.
B.Strictly prohibit children from using devices.
C.Have a sincere communication with children.
D.Evaluate the impact of screen time on children.
