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.

Science fiction often presents us with planets that speak a single language. However,1. humans can express themselves in several thousand languages is a delight. Few would welcome the loss of this variety, and, along with it, a multiplicity of nations and cultures.
Unfortunately, the days 2. English shares the planet with thousands of other languages are numbered. A traveler to the future is likely to notice two things about the language landscape of Earth. One, there will be vastly fewer languages. Two, languages will be 3. (complicated) than they are today.
By 2115, it’s possible that only about 600 languages will be left on the planet as opposed to today’s 6,000. Too often, colonization has led to the disappearance of languages: Native speakers are punished 4. using their own languages. Urbanization has only furthered the destruction by bringing people away from their homelands to cities where a single language dominates.
In addition, it is easy for speakers to associate larger languages with opportunities and smaller ones with backwardness. Consequently, people stop passing on smaller languages to their children.
There are diligent efforts 5. (keep) endangered languages from dying. Sadly, few are likely to lead to communities’ 6. (raise) children in the languages, which is the only way the languages exist as their full selves.
Instead, many communities create new versions of the languages, with smaller vocabularies and simpler grammar. The Irish Gaelic (盖尔语) proudly spoken by today’s English-Gaelic bilinguals is an example, something that one might call a “New Gaelic.”
Linguists have no single term yet for these new speech varieties, 7. from Germany’s “Kiezdeutsch” to Singapore’s “Singlish,” the world is witnessing the birth of more optimized versions of old languages. This simplification should not be taken as a sign of decline. All of the “optimized” languages remain full languages in every sense of the term.
We 8. regret the eclipse of a world where 6,000 different languages 9. (speak), but fortunately, it seems a decent amount of linguistic diversity will be preserved. Besides, 10. languages become easier to pick up, the future may promise even more mutual comprehension.

The Benefits of Being Bilingual
At one time being bilingual was thought to slow down brain development, although it is now known to have many benefits. Aside from professional and social benefits, studies show that the process of learning a second language actually strengthens some areas of the brain.
To start off with, a study done at the University of British Columbia shows that babies exposed to two languages before birth don’t confuse the languages. Moreover, it showed that the effort it takes to keep the languages separate improves perception.
The benefits aren’t only for people who grow up bilingual, however. Anyone who learns a second language during their lifetime will have certain advantages. For one, Swedish scientists found that the brain grows during language learning, particularly the area where memories are created.
Not only does the brain grow, but language learners also improve in many areas. They are good at multitasking while paying detailed attention to each task. Additionally they strengthen their math skills, listening skills, ability to focus, problem-solving skills, reading and vocabulary in their native language, and their memory increases. In the area of math, a study done at the University of Washington shows that bilinguals solve new math problems half a second faster than monolinguals.
Language learning also has huge benefits for old age. Brian Gold of the University of Kentucky did a study comparing the ability of bilingual seniors and monolingual seniors to do an attention-switching task. Usually this skill fails with age. However the bilingual seniors performed better than the monolinguals, and their brains worked less hard and more efficiently.
Neuroscientists (神经系统科学家) think that having more brainpower at an older age helps protect us from Alzheimer’s. Current medication for Alzheimer’s only delays it for 6-12 months, while learning a new language delays it for 4-5 years. Again, this is not only for people who learn a second language from birth. Even if you don’t learn another language until after middle age it helps. Language learning keeps your brain active and “fit”.

Each of us has a time of the day when we’re at our best. For some, it’s the morning, and for others, the afternoon or evening. These times relate to what scientists call our circadian clock (生物钟). 1.
The research is the work of two authors, Aaron Schirmer and Benjamin Smarr. The pair used data from a university computer system to study the rhythms and activities of 15,000 students at Northeastern Illinois University between 2014 and 2016. They studied the data to see if there was a connection between the students’ schedules, their natural circadian clocks and their school performance.
2. But if students’ clock doesn’t agree with the rest of their lives, their performance was likely to suffer.
According to the study, those students who suffered from a mismatch underwent a kind of “social jet lag（时差）”. For example, some students performed best at night and therefore chose to study in the evening. But if those students had an early morning class, they often felt tired from late night studying and didn’t get the most out of the class. They might then go on to get a lower grade for exams and coursework. 3.
The authors say mismatches between a student’s schedule and circadian clock can have a harmful effect, and not just in terms of academic performance. Social jet lag can also be bad for students’ health.
The authors don’t claim their study proves anything, but they do say that it provides food for thought for school administrators, who might like to think about special ways to help students who suffer on account of their schedules. 4.
A.In addition, the findings alerted parents to their children’s sleeping patterns.
B.The study found that the closer a student’s schedule and their circadian clock, the better their grades were.
C.All students in the study suffered some degree of social jet lag, but late-night studiers suffered the most.
D.The clock genes create circadian rhythms in the body, which help control the timing of a variety of biological changes.
E.The findings could also help everyone to be aware, and hopefully take advantage, of their own biological rhythms to lead a healthy life.
F.Now, a new study suggests that the relationship between students’ circadian clocks and their study schedules can have a big effect on their grades.
