On Sunday, March 11, most Americans will set their clocks forward an hour, as daylight saving time (sometimes wrongly called daylight savings time) begins and most of the United States can enjoy an extra hour of daylight. The spring and fall clock changes continue a long tradition started by Benjamin Franklin to conserve energy.

Benjamin Franklin lakes the honor (or the blame, depending on your view of the lime changes) for coming up with the idea to reset clocks in the summer months as a way to conserve energy. By moving clocks forward, people could take advantage of the extra evening daylight rather than wasting energy on lighting. At the time, Franklin was ambassador to Paris and so wrote a letter to the Journal of Paris in 1784, rejoicing over his “discovery” that the sun provides light as soon as it rises.

Even so, DST (Daylight Saving Time) didn’t officially begin until more than a century later. Germany established DST in May 1916 as a way to conserve fuel during World War I. The rest of Europe came onboard shortly thereafter. And in 1918, the United States adopted DST.

Though President Woodrow Wilson wanted to keep daylight saving time after WWI ended, the country was mostly rural at the time and farmers objected, partly because it would mean they lost an hour of morning light. And so daylight saving time was abolished until at the start of WWII, on Feb. 9, 1942, President Franklin Roosevelt re-established daylight saving time year- round, calling it “War Time.”

After the war, a free-for-all system in which U.S. states and towns were given the choice of whether or not to observe DST led to disorder. And in 1966, to avoid such “Wild West” confusion, Congress passed the Uniform Time Act. That federal law meant that any state observing DST — and they didn’t have to jump on the DST system — had to follow a uniform timing system throughout the state in which daylight saving time would begin on the first Sunday of April and end on the last Sunday of October.

Then, in 2007, the Energy Policy Act of 2005 went into effect, expanding the length of daylight saving lime to the present timing.

1.What is the passage mainly about?

A. What is Daylight Saving Time?

B. How did Daylight Saving Time start?

C. Who proposed Daylight Saving Time?

D. Why Daylight Saving Time is adopted?

2.It can be inferred that 　　　　 .

A. DST was adopted in the US mainly to preserve fuel

B. DST lasted for 24 years in the US before being canceled

C. it is still free for the states in the US to adopt the DST or not

D. farmers in the US rejected DST for losing an hour of evening light

3.What is the meaning of the underlined expression “rejoicing over” in paragraph 2?

A. Taking pride in.　　 B. Taking interest in.

C. Feeling regret for.　　 D. Feeling surprised about.

4.Which country adopted DST earliest, according to the passage?

Most airlines go all out to ensure their passengers have the best possible flight experience. Now, Europe's low-budget airline, easyJet, wants to extend the positive experience beyond the plane ride with “Sneakairs” 一smart shoes that allow visitors to explore new cities and towns without ever looking at a map.

To transform Sneakairs from an ordinary shoe to a tour guide，all the wearer has to do is enter his or her desired destination into the easyJet smartphone app. A built-in GPS will determine the wearer’s starting location while the Google Maps navigation (导航）tool will help chart the best route. Whenever a change of direction is necessary, the app will communicate with the appropriate shoe via the Bluetooth and cause it to vibrate(振动）. For example, if the wearer needs to turn right, he/she will feel the sensation in the right shoe. Should the user miss the turn, the smart shoes will both vibrate at the same time, reminding him/her to change course.

Visitors that wander off the suggested path or decide to take a break for a cup of coffee or a meal have nothing to worry about. The smart app will automatically determine the new location and chart out a new route. Once the desired destination is reached, Sneakairs will vibrate three times to inform the user of the arrival and then go back to being ordinary shoes—until their navigation services are needed again!

Sneakairs is certainly not the first navigation shoe in the market. However, easyJet is the first airline to offer them to passengers just as they are about to land in an unknown city. However, before Sneakairs can go mainstream, the easyJet team still needs to make some adjustments. Among the challenges that need to be addressed is the smart shoe’s three-hour battery life, which is hardly enough for a tourist to catch all the delights a new city or town has to offer!

1.What can we learn about Sneakairs in the text?

A. Its size. B. Its price.

C. Its material. D. Its function,

2.What does the author mainly talk about in Paragraph 2?

A. How Sneakairs works.

B. How visitors choose routes.

C. How users avoid getting lost.

D. What users should pay attention to.

3.What might easyJet do to improve its smart shoes?

A. Bring down their cost.

B. Add more functions.

C. Develop more types.

D. Make the battery last longer.

4.Where does this text probably come from?

A. A commercial ad. B. A science report.

C. A tourist map. D. An airline guide.

Most people know that listening to music when they are feeling down or depressed can encourage their spirits.

However studies have also shown that music, especially certain tones can reduce stress. Music can change brainwave patterns, deepen breathing, and bring on a totally stress-free and more open mindset（心态）. Using music to relax when considering a particular problem may not only raise your mood, but also could help you reach that "a-ha"moment and find a solution.

Music has also been shown not only to make you feel good, but also, to be a great motivator. For example, during exercise, listening to music can keep you going, or get you to exercise more by helping you to ignore negative feelings of tiredness and focus on the pleasurable feelings you get from being absorbed in the music.

Music is mainly used to record emotion. When we listen to a piece of music we share the artist's feelings on a visceral（本来的）level. That can be sad, and who among us hasn't put on a painful love song to share in the misery after a bad break-up? On the contrary, we can share in the delight of songs of joy and happiness, or any song or piece of music that reminds us of a particular happy time in our past.

So next time you are feeling down, put on Beethoven' s Ode to Joy, I bet you will feel a lot better about whatever it was that was bothering you!

Ian Mercer doesn’t set an alarm clock. The former Microsoft senior manager doesn’t check the weather, either. He doesn’t turn on lights, water the yard, or adjust the thermostat(恒温器). He doesn’t open the curtains, answer the phone, or call his children for dinner. There’s something unique about Ian’s home. He has programmed it to do all these things for him.

Ian doesn’t live in a typical home or have a typical lifestyle. He spent over a decade designing the systems that feature in his unique home. He bought a home automation software package and then improved it.

Now there are 79 sensors and monitors, and 48 light switches in his home. Lights turn on automatically in rooms with people in them. Even being out, Ian can also control his home remotely using voice commands or his phone in any location. That is only the beginning of what this home has been programmed to do.

It connects with online calendars, caller ID, online weather services, online address boos, and email, among other things, to get Ian through his day. For example, if there is a meeting in Ian’s calendar, it will wake him up, open his bedroom curtains, start and set his shower to his desired temperature. It also informs Ian about traffic conditions.

There is plenty more this home has been programmed to do. It keeps him updated on his favorite sports teams and scores. It even monitors online activity to check that Ian’s children are doing their homework. The “dinner’s ready” command stops operation of their computers and TVs. This is easier than asking his children o shut them down.

People may set an alarm on the phone or clock that sounds like this: beep beep beep. That hard, unpleasant sound may be making it harder to shake off the sleepy feeling in the morning known as grogginess. So, is there a better way to wake up? A recent study says yes. The answer is music.

The study, carried out by researchers in Australia, involved 50 people. The researchers found that people who wake up to musical alarms reported feeling more awake and alert. Stuart McFarlane, a lead writer of the study stated, "We are very surprised by these findings as one might expect a harsh beeping sound to be more successful," at waking up a person.

Sleep inertia is another term for grogginess. It means a person has a heavy feeling when waking up, and has trouble getting moving again after sleeping. McFarlane said people need to better understand sleep inertia's harmful effects on human performance later in the day.

Not everyone will experience the full effect. But for those who do, "care should be taken" when performing duties that require a top performance within this period, he said. This includes "dangerous tasks like driving or riding our bikes" shortly after waking up. The same is true for people who work in dangerous situations shortly after they wake, including firefighters and pilots.

So, what makes musical alarms better for waking up? The researchers think the music may be more successful in reducing sleep inertia because it has several tones, compared to the single tone of a "beeping" alarm. McFarlane said that the changes over time between the music tones may help increase a person's attention when waking from sleep.

And is there a kind of music that is best to wake up to? There may be, McFarlane said. "We could suggest alarm sounds that are tune full and easy to hum or sing along with. The current sounds I have been using include 'Close to me' by the Cure and 'Borderline' by Madonna."

No matter how you wake up, experts say, the amount of sleep you get also matters — a lot.

1.Which of the following might be the best title for the text?

A.What is grogginess? B.Why are musical alarms better?

C.Which music is the best? D.How can we overcome grogginess?

2.Which of the following statements is TRUE according to the passage?

A.Sleep inertia is another cause for grogginess.

B.How long a person sleeps is of great importance.

C.The 'beeping' alarm is not effective mainly because of its noisy tone.

D.It is dangerous for everyone to drive or ride bicycles shortly after waking up.

3.The paragraph following this passage is likely to focus on 　　　　 .

A.examples of good musical alarms

B.more findings of the application of music

C.explanations about why music is more helpful

D.suggestions on how to sleep well and feel fresh each morning

4.In which section of a magazine may you find the passage?

A.Health. B.Fiction.

C.Technology. D.Entertainment
