In recent years,American teens 【小题1】（earn） less than stellar（优秀的）scores on the national exam. A new analysis from the Center for American Progress argues for one simple step 【小题2】（help）raise these scores:Start school later in the day.

【小题3】（delay）start time by an hour across the country could improve students math scores up to eight 【小题4】（point）, the analysis says. That's almost one grade level of learning. The idea is that giving sleep-lacking teens more time to sleep 【小题5】 they hit the books will help them learn better.

In the previous study conducted in 2012 , middle school students 【小题6】 switched schedules to start school an hour later saw their test scores increase. And among them the low-performing students saw the 【小题7】（big）increase.

The Center for American Progress considered what would happen if those results 【小题8】（repeat） around the country.

“What we found is the impact 【小题9】 student achievement would be quite large,” Ulrich Boster, a senior fellow at the center, told The Huffington Post. “Starting school later could 【小题10】（significant）improve students' outcomes. ”

As the saying goes, time is money. And in my opinion, time is even precious than money. Why? Because when money is spent, we still have a chance to earn them back. But when time is wasting, we can never get it back. There is no doubt whether time is very limited, and even a minute is of great value. We should make fully use of time to do what should be done. It’s the pity that a lot of people still didn’t appreciate the value of time. They are wasting their time doing nothing of useful. We should form the good habit of race against time and make a difference in our world.

   The paperless office was first invented in 1975. Four decades later, we’re still chasing (追逐) the paperless office dream. Take the financial industry for example — it is one of the slowest industries to hug digital transformation. Many financial institutions today still send out trade confirmations (确认函) by mail. I can tell you from first-hand experience that going paperless is by no means impossible. The Centric Digital office is a paperless work environment where all the office operations go digital, which has amazed our business partners.

Actually, companies need to stress the benefits of a digital culture. Going paperless can save time and money. You could say goodbye to costly repairs, office supply orders, wasted employee time and so on. Besides, forbidding paper in the office forces information to be 100% digital, where you can make countless backups (备份), which easily increases transparency (透明). Not to mention, top talents want to work for digital companies.

You might think the secret to a paperless company is purely technology. Well, not really. Thanks to products like iPads, smartphones, and cloud services, the ability to go paperless is highly accessible. Yet, even with all this technology, companies continue to rely on paper. It’s not because they don’t have access to the technology, but because they’re lacking the policies, organizational structure, and strong desire to change. In order to go paperless, companies need to change the way they think and operate. The decision needs to be made and carried out, and everyone needs to work together to make it.

Yes, the paperless office has been a very long time in the making — but it no longer has to be. With plenty of software, services, apps, and technology available today, the only thing we need to do is make the decision to go paperless and see it through.
