The £109 Nest Protect Smoke Alarm promises Internet alerts(警报)and an end to the low battery chirp(短而尖的叫声). Besides, it uses a voice to tell you where the fire is.
The alarm is the first UK product from Nest, which is run by iPod-inventor Tony Fadell. The company claims the device’s batteries will last for up to seven years. The device will offer a spoken warning before it sounds a major alarm. Also it will use text messages and apps on your phones to alert users to low-level risks.
The present smoke alarms constantly alert users to non-existent threats, which will make many users annoyed and finally remove their batteries altogether. “We’ve all experienced the smoke alarm going off while we’re cooking. Sometimes, we need to search for the source of that non-stop low-battery chirp at midnight,” said Fadell. “Therefore, every time a smoke alarm cries wolf, we trust it a little less, and then — in a moment of frustration — we take the batteries out to stop the beep(嘟嘟声). And that leaves us and our families at risk.”
If the Protect smoke alarms are used, they can be set up in up to ten zones, so that the clear warnings tell users where the risk has been detected.
“Safety shouldn’t be annoying,” said Matt Rogers, Nest founder and vice president of engineering. “It was unacceptable to us that one in eight houses in the UK has a non-functioning smoke alarm. These products are required by law and are supposed to keep us safe, yet people hate them. We wanted to change that.”
小题1:For what purpose did Nest create the Protect Smoke Alarm?
A.To predict low-level fire risks.B.To experiment with a new battery.
C.To improve present smoke alarms.D.To avoid the low-battery chirp.
小题2:What did Tony Fadell really want to tell us in Paragraph 3?
A.One of his cooking experiences.
B.Disadvantages of present smoke alarms.
C.His growing distrust of smoke alarms.
D.His source of annoyance to crying wolf.

c. Longer battery life            d. Going off constantly
e. Internet connection
A.a, b, cB.c, d, eC.a, c, eD.b, c, e
小题4:What can we know from the last paragraph?
A.In the UK people seldom set up smoke alarms.
B.Matt Rogers didn’t like the safety requirements.
C.Non-functioning smoke alarms make people annoyed.
D.The government should pay attention to safety issues.

Choosing the Right Resolution (决定)
Millions of Americans began 2014 with the same resolution they started 2013 with, a goal of losing weight. However, setting weight loss as a goal is a mistake.
To reach our goal of losing weight --- the output, we need to control what we eat --- the input ( 输入). That is, we tend to care about the output but not to control the input. This is a bad way to construce goals. The alternative is to focus your resolution on the input. Instead of resolving to lose weight, try an actionable resolution: “I’ll stop having desert for lunch,” or “I’ll walk every day for 20 minutes.” Creating a goal that focuses on a well-specified input will likely be more effective than concentrating on the outcome.
Recently a new science behind incentives (激励) , including in education, has been discussed. For example, researcher Roland Fryer wanted to see what works best in motivating children to do better in school. In some cases, he gave students incentives based on input, like reading certain books, while in others, the incentives were based on output, like results on exams. His main finding was that incentives increased achievement when based on input but had no effect on output. Fryer’s conclusion was that the intensives for inputs might be more effective because do not knoe how to do better on exam, aside from general rules like “study harder.” Reading certain books, on the other hand, is a well-set task over which they have much more control.
As long as you have direct control over your goal, you have a much higher chance of success. And it’s easier to start again if you fail, because you know exactly what you need to do.
If you want to cut down on your spending, a good goal would be making morning coffee at home instead of going to a cafe, for example. This is a well-specified action-based goal for which you can measure your success easily. Spending less money isn’t a goal because it’s too general. Similarly, if you want to spend more time with your family, don’t stop with this general wish. Think bout an actionable habit that you could adopt and stick to, like a family movie night every Wednesday.
In the long run, these new goals could become a habit.
小题1:The writer thinks that setting weight loss as a goal is a mistake because _______ .
A.it is hard to achieve for most Americans
B.it is focused too much on the result
C.it is dependent on too many things
D.it is based on actionable decisions
小题2:In Roland Fryer’s research, some students did better than the others because ______ .
A.they obeyed all the general rules
B.they paid more attention to exams
C.they were motivated by their classmates
D.they were rewarded for reading some books
小题3:According to the writer, which of the following statements is a good goal?
A.“I’ll give up desert.”
B.“I’ll study harder.”
C.“I’ll cut down my expense”
D.“I’ll spend more time with my family”
小题4:The writer strongly believes that we should ________ .
A.develop good habits and focus on the outcome
B.be optimistic about final goals and stick to them
C.pick specific actions that can be turned into good habits
D.set ambitious goals that can balance the input ang output

One of India’s top engineering schools has restricted Internet access in its boarding houses, saying addiction to surfing, gaming and blogging was affecting students' performance, making them lonely and even suicidal.
Authorities at the best Indian Institute of Technology (IIT) in Mumbai said students had stopped socializing and many were late for morning classes or slept through them. “Now, a student doesn’t even know who lives two doors away from him because he is so busy on the Internet,” said Prakash Gopalan, dean of student affairs. “The old dormitory culture of companionship and socializing among students is gone. This is not healthy in our opinion.”
IIT-Mumbai, with about 5,000 students, is one of seven IITs across India which are considered to be among the finest engineering schools in the world. They are also a talent pool for global technology giants. But their hard courses, tough competition and lonely campus lifestyle have taken an effect on students. Depressive and dysfunctional(不正常的) lifestyles are known to be common among IIT students, and at least nine have committed suicide in the past five years. Students have unlimited free Internet access in their boarding houses to help them in their studies, but many also use it to surf, chat, download movies and music, blog and for gaming.
Starting Monday, Internet access will be banned between 11 p.m. and 12.30 p.m. at IIT-Mumbai’s 13 boarding buildings to encourage students to sleep early and to try and force them out of their “shells”, Gopalan said. But the move has not gone down well with students who say they hate their lives being regulated. “Now they will say we need to listen to a lullaby(摇篮曲) to go to sleep,” said Rajiv, an electronics student.
小题1: What measure has been taken in IIT- Mumbai?
A.Students have unlimited free Internet access in their dormitories.

If you want to help children develop language and speech skills, UCLA researchers say, listening to what they have to say is just as important as talking to them.

The effect of a conversation between a child and an adult is about six times as great as the effect of adult speech input(输入)alone, the researchers found. “Adults speaking to children helps language develop, but what matters much more is the interaction, ”said the study’s lead author, Frederick   Zimmerman, an associate professor in the School of Public Health at the University of California, Los Angeles.  The researchers also found that TV viewing didn’t have much of an effect—positively or negatively—as long as it wasn’t displacing conversations between an adult and a child.
The UCLA study included 275 families with children between 2 months and 48 months old.  They represented a variety of incomes and education.  The researchers found that, in an average day, children heard about 13, 000 spoken words from adults and participated in about 400 adult-child conversations a day.
Assessed separately, factors positively associated with language development included each additional 100 conversations a day and each 1, 000 words increase in the number of words spoken by adults and heard by children.  When looked at alone, TV was negatively associated with language development.  But, when these three factors were analyzed together, the only one that stood out was conversation between adults and children.
“The more a child speaks and interacts with an adult, the better idea a parent has about where the child is”, Zimmerman said. “Although it’s mostly done unconsciously, parents will provide feedback and correct mistakes.  They’ll also tailor their speech to the child.  Parents can give the children words by talking to them about what they’re doing, such as, ‘I’m putting on your pajamas now’.  But give your child the opportunity to talk, hopefully without the rest of the noise in the environment, ”she added. “If parents can carve out some conversation time—maybe at bath time or at dinner time—that’s a wonderful thing. ”
小题1: The researchers also found that TV viewing    .
A.could have a positive effect on a child’s language development
B.had a little effect on a child’s language development
C.affected a child’s language development more negatively than positively
D.affected a child’s language development both negatively and positively
小题2:Frederick Zimmerman would probably agree that    .
A.parents should let their children talk most of the time
B.children should watch TV programs selectively
C.the conversation between parents and children should be two-way
D.it’s no good for parents to correct their children’s mistakes when they are speaking
小题3: We can conclude from the last paragraph that    .
A.parents should let a child repeat what he or she says
B.bath time or dinner time is the best chance for parents to talk to a child
C.parent-child conversation can be carried out at any proper time
D.parents should leave a child talking alone
小题4: What would be the best title for the passage?
A.Talk with kids, not at them

Harvard student Julie Zauzmer turned 20 on January 22, and her birthday couldn’t have been better: She got to working the overnight shift at the Harvard Square Homeless Shelter.
That might seem an extraordinary act of selflessness for someone turning 20. But there’s increasing evidence that commitment to community service is becoming much more ordinary to today’s young adults.
“Young adults are doing more volunteer service than in any point in history,’’ said Scott Seider, an assistant professor of education at Boston University who studies the civic development of young adults.
At Harvard, the Winthrop Street Homeless Shelter is one of 86 social service programs associated with the Phillips Brooks House Association, which is a student-run nonprofit organization. Students can work with deaf children, bring pets to nursing homes, and prepare Chinese students to become US citizens, and so on.
Volunteerism develops well outside of colleges, too. Applications to AmeriCorps have risen to a very high level, jumping from 91,399 in 2008 to 258,829 in 2010. City Year, which puts young people in high-poverty schools as tutors and mentors for at-risk students, has had a 140 percent increase in applications since its 2007-2008 service year. Citizen Schools, which uses volunteers to work with students in middle schools, has had a 28 percent jump in applicants between 2008 and 2009.
“Most of my friends know it’s their duty to give back before they settle down,’’ said Samantha Wolf, a 23-year-old Boston University graduate serving with City Year in a Mattapan school.
City Year corps member Antonio Gutierrez, 22, graduated last year from Union College in Schenectady, N.Y., and is applying for admission to law schools, but this year he is tutoring and mentoring students at the Blackstone Elementary School in the South End.
“I grew up in similar circumstances,’’ said Gutierrez, who said he was a weak student until enrichment programs changed his academic trajectory (轨迹). Raised by a single mother in low-income housing across the street from City Year’s South End Headquarters, he used to watch the red-jacketed corps members come and go, and decided to become one someday.
小题1:We learn from what Scott Seider says in Paragraph 3 that young people today       .
A.study harder than before
B.do more volunteering than ever before
C.don’t care much about others
D.like to find jobs in their communities
小题2:What’s the goal of the program of City Year?
A.It helps to find jobs for college students.
B.It offers shelters to the homeless people.
C.It helps to build schools for poor students.
D.It engages young people to teach at high-poverty schools.
小题3:What do we know about Antonio Gutierrez?
A.He wants to give back as a volunteer.
B.He has always been an excellent student.
C.He never expected to become a volunteer.
D.He now works as a teacher.
小题4:What would be the best title for the text?
A.Volunteering spirit has disappeared
B.How to become a college student
C.College students learn to give back
D.The real life of young adults today

ARE you a dog person or a cat person?
With so many photos and videos of cats and dogs doing cute things online, it’s easier than ever to answer which of these furry friends you like more. There are many reasons why people prefer one type of pet over the other. So, have you ever wondered what your preference for cats or dogs says about you?
In fact, a 2010 study done by Sam Gosling , a psychologist at the University of Texas, US, and his graduate student Carson Sandy found that dog people are more extroverted(外向的)agreeable and serious than cat people.
“Cats will occasionally engage in social activities, but usually after only a few minutes they will abandon the game. Dogs, on the other hand, will often engage in play, like fetching a thrown lull, for hours at a lime," said Modem Dog magazine.
Just on the basis of dogs' nature being more sociable than cats’, you may expect that the personalities of dog people also reflect higher sociability. And Cosling’s study found that dog people are generally about 15 percent more extroverted and 13 percent more agreeable, both of which are associated with social altitude.
In addition, dog people are 11 percent more conscientious than cat people.
“Conscientiousness" is a tendency In show self-discipline(自律),to complete tasks and aim for achievement. This quality also shows a preference for planned rather than spontaneous (一时冲动的) behavior.
In comparison, cat people an; about 12 percent more anxious, but they are also 11 percent more “open” than dog people, due to a general appreciation for art, emotion, imagination, curiosity, adventure, unusual ideas and variety of experience. And people high on openness are more likely to hold unconventional beliefs.
Despite vast differences, there an some things that cat people and dog people have in common. “Both types of people consider themselves close to nature, dislike animal-print clothing and generally optimists. ” noted Mother Nature Network.
小题1:What does the article mainly talk about?

In Egyptian myth, Apophis was the ancient spirit of evil and destruction, a demon (恶魔) that was determined to throw the world into darkness forever. A fitting name, astronomers reasoned, for a threat now rushing towards Earth from outer space. Scientists are monitoring the progress of a 390-metere wide asteroid (小行星) discovered last year, which is potentially on a collision (碰撞)course with the planet.
NASA has estimated that Apophis has an outside chance of hitting the Earth in 2036. If it did hit us, thousands of square kilometers would be directly affected by the explosion but the whole of the Earth would see the effects of the dust sent into the atmosphere. At a recent meeting of experts in Near-Earth objects (NEOs) in London, scientists said it could take decades to design, test and build the required technology to deflect the asteroid.
The Apophis asteroid is placed at four out of ten on the Torino scale—a measure of the threat caused by an NEO where 10 is a certain collision which could cause a global disaster. This is the most possible danger of any asteroid in recorded history and it has a 1 in 37 chance of hitting the Earth.
Alan Fitzsimmons, an astronomer from Queen’s University Belfast, said, “When it does pass close to us on April 13, 2029, the Earth will deflect it and change its orbit. There is a small possibility that if it passes through a particular point in space, the so-called keyhole, the Earth’s gravity will change things so that when it comes back around again in 2036, it will collide with us.” The chance of Apophis passing through the keyhole, a 600-meter patch of space, is 1 in 5,500, based on current information.
There is no shortage of ideas on how to deflect asteroids. The Advanced Concepts Team at the European Space Agency has led the effort in designing a range of satellites and rockets to nudge asteroids that are on a collision course for Earth into a different orbit.
小题1:The best title for this passage would be ___________.
A.Apophis Asteroid, a Possible Destroyer of Earth
B.Apophis, a Good Name for Dangerous Asteroid
C.Our Planet Will Be Ruined in 2036
D.Scientists Study Apophis Asteroid
小题2:The name Apophis mentioned in the passage indicates that the asteroid is _________.
A.powerfulB.mysteriousC.boringD.destructive
小题3:The underlined word “deflect” in Paragraph 2 probably means _________.
A.destroy the quality of
B.change the direction of
C.measure the size of
D.look into the truth of
小题4:Which of the following is NOT true?
A.If Apophis hit the earth, its impact would be enormous.
B.No way to deal with Apophis is available at present.
C.Apophis is the first dangerous asteroid in recorded history.
D.It is uncertain whether Apophis will hit the earth in 2036.
小题5:What would the passage talk about if it continued?
A.An Egyptian myth about Apophis.
B.NASA’s study on NEOs.
C.How the keyhole influences Apophis.
D.What methods can be used to deflect the asteroid.

Let children learn to judge their own work. A child learning to talk does not learn by being corrected all the time; _________________, he will stop talking. He notices a thousand times a day the difference between the language he uses and the language those around him use. Bit by bit, he makes the necessary changes to make his language like other people’s. In the same way children, learning to do all the other things without being taught to walk, run, climb, whistle, ride a bicycle, compare their own performances(表现)with those of more skilled people, and slowly make the needed changes. But in school we never give a child a chance to find out his mistakes for himself, let alone correct them. We do it all for him. We act as if we thought that he would never notice a mistake unless it was pointed out to him, or correct it unless he was made to. Soon he became dependent on the teacher.
Why should we teachers waste time on such tiring work? Our job should be to help the child when he tells us that he can’t find the way to get the right answer. Let’s end all this nonsense(荒谬的)of grades, exams and marks. Let us throw them all out, and let the children learn what all educated persons must someday learn, how to measure their own understanding, how to know what they know or do not know.
We should, of course, offer help to them just as they ask for it. The idea that there is a body of knowledge to be learnt at school and used for the rest of one’s life is nonsense in a world as complicated(复杂的)and rapidly changing as ours. Don’t worry! If something is basic, they will go out into the world and learn it.
