iPads vs Textbooks
What if you could have your whole backpack at the touch of your fingertips? In the first month of the Apple iPads release, 25million were sold! People all over the world use iPads for all sorts of different things, but one of their finest qualities is the ability to be a textbook. 1.
To begin with, iPads are less expensive. Textbooks become outdated and schools have to buy new books, but with an iPad schools can update them for free. 2. Schools don’t have to spend $500 every year for iPads because they last a while and can be updated.
3. Students usually have multiple classes, which results in multiple textbooks. Heavy backpacks filled with books can cause back problem. A solution to that is an iPad, which only weighs 1.33 pounds and can hold all of a student’s textbooks.
Third, schools should get rid of their textbooks and get iPads because they have more capabilities. Some might think all of the apps are distracting, but the apps actually make iPads more efficient. 4. Textbooks cannot do those tasks, but iPads can easily do them with just a tap of the fingertip.
Lastly, iPads are a better choice for schools instead of textbooks because these devices allow students to access their learning anywhere at any time. 5. With iPads, they find it easier to get their homework done.
In conclusion, schools should get rid of their clumsy textbooks and switch to iPads. iPads have allowed this generation to have their entire backpack in the palm of their hands.
A.Second, iPads cost less and are more popular.
B.These tablets are perfect for busy students.
C.Therefore, they can use the saved money for other programs.
D.Moreover, in high school, textbooks have an average of 4.8 pounds each.
E.iPads have already replaced textbooks in over 600 American counties.
F.Schools have every reason to do away with their school books and switch to iPads.
G.iPads absorb the need to buy calculators, dictionaries, and other items that are found within the device.
The different parts of a health-care system have different focuses. A hospital’s stroke unit monitors blood flow in the brain. The cardiac (心脏的) unit is interested in that same flow, but through and from the heart. The data is effective in its own field, but for the most part has little relevance to other bits of the body and conditions.
Apart from all this, the instruments that doctors use to monitor health are often expensive, as is the training required to operate them. That combined cost is too high for the medical system to scan regularly, for early signs of illness.
A research project called AlzEye, run from Moorfields Eye Hospital in London, may change this. It is attempting to use the eye as a window through which to detect signals about the health of other organs. The doctors in charge of it, Siegfried Wagner and Pearse Keane, are linking Moorfields’ database of eye scans, which offer a detailed picture of the health of the retina (视网膜), with information about other aspects of its patients’ health collected from other hospitals around England.
The data set includes every one of the 300,000 patients who visited Moorfields between 2008 and 2018 and was over the age of 40. The idea is to examine changes to people’s eyes within that ten-year period, and link these with, say, the appearance of Alzheimer’s disease in the same patient.
Drs Wagner and Keane are searching for patterns in the eye that betray the appearance of disease elsewhere in the body, and are focusing first on Alzheimer’s disease. They will seek such patterns with the help of algorithms (程序) that can spot far tinier variations. They may, it should be remembered, never find such patterns. Although there is evidence that the back of the eye does change as its owner develops Alzheimer’s, it may be that the changes are too small to be detected reliably enough for diagnosis (诊断). If such patterns could be recognized reliably, though, the potential impact would be huge. Even in rich countries, between 50% and 80% of Alzheimer’s cases go undiagnosed. Moreover, even if the technique does not work for Alzheimer’s, it might work for something else. Dr Wagner and Dr Keane therefore plan further searches for patterns related to strokes and heart disease. Even one relevant pattern would contain a remarkable diagnostic leap forward.
If it does work, the technique the two researchers are recommending will be cheap to carry out. An indication of how cheap is the project’s total budget of just £15,000. Also, the equipment and algorithms to perform an eye scan are available to anyone, through cloud-computing services like Google and Amazon.
1.What is the disadvantage of the traditional way to monitor health?
A.Doctors are only interested in their own fields.
B.It can’t find early signs of illness effectively.

2.Drs Wagner and Keane use eye scans to _______.
A.decide whether the patients’ retinas are healthy
B.compare Moorfields’ database with other hospitals’
C.find the connections between eye changes and disease
D.explore the use of algorithms in detecting Alzheimer’s
3.The underlined word “betray” in Paragraph 5 is closest in meaning to _______.
A.change B.show
C.cause D.prevent
4.What do we learn about the AlzEye project?
A.It examines the lifelong changes to 300,000 patients’ eyes.
B.It can correctly diagnose Alzheimer’s cases by scanning eyes.
C.It may be applied in finding other diseases besides Alzheimer’s.
D.It provides cloud-computing services with Google and Amazon.
Small talk—the likes of “What do you have there? Popcorn?” or “The weather today is beautiful, isn’t it?”—is meaningless and a waste of time, according to some people. But scientists believe that it is actually more useful than it may appear to be.
One example comes when you are on a train or a plane. The thought of talking to the stranger sitting beside you can be scary, because you know the conversation is sure to be awkward. But a study by the University of Chicago in the US found that people who chat to strangers enjoy a better ride than those who sit in silence or occupy themselves with their phones.
In the study, researchers asked people at Chicago train stations to start conversations with fellow travelers. Most of them refused to do so at first because they expected not to get a friendly answer. But the result turned out to be just the opposite—most strangers were not only willing to be talked to, but also pleasant to talk to.
“Human beings are social animals,” Nicholas Epley, one of the lead researchers, told Live Science. “Other people are people, too. And it turns out that they’d like to get to know you.”
Apart from making you happier, small talk with strangers can also help you feel connected to your surroundings. Previous studies found that when people are frequently smiled at, made eye contact with and spoken to at coffee shops, they tend to have a stronger sense of belonging instead of feeling like they are being ignored and left out.
And if you are already comfortable enough to make small talk with strangers, you should try to develop it into something “bigger”.
A 2010 study proved that having a deep and meaningful conversation gives you even more happiness than small talk. Participants in the study—79 college students—reported after the four-day experiment that they were much happier when they had a third as much small talk and twice as many in-depth conversations.
But deep conversations can start with small talk, can’t they? So the first step is to start talking, no matter how casual the topic is. And who knows, maybe an opening line as simple as “I like your hat” could lead to a serious conversation in which you learn something new from a stranger.
1.Why are most people willing to have a talk during a trip, according to Nicholas Epley?
A.Most people are nice to strangers.
B.People are naturally curious about others.
C.People are afraid of loneliness or boredom.
D.People try to show their good side to strangers.
2.Which of the following is a benefit of small talk?
A.Wasting less time.
B.Developing useful contacts.
C.Disconnecting from phones for a while.
D.Feeling like being a part of your surroundings.
3.According to the 2010 study, in what way can people get more happiness from talking with strangers?
A.Starting with serious topics. B.Starting with casual topics.
C.Making it important and deep. D.Choosing pleasant surroundings.
4.What is the author’s attitude toward small talk?
A.Supportive. B.Negative.
C.Doubtful. D.Objective.
