One of the biggest enemies of smartphone batt...

One of the biggest enemies of smartphone batteries is the phones ’ screens. The screens keep getting bigger, and they need to keep bright for outdoor use. 1. But, a new OLED technology can increase brightness and energy efficiency ( 效率). The technology is being developed by a team at the Imperial College London. They’re using a special development process to produce OLEDs that give off polarized light　 (偏振光).

So, what's that all meaning? Screens often include filters (滤光器) to help reduce unpleasant bright light from outside. 2. However, they also can prevent lots of the light from the screen itself. Any light that doesn’t make it to your eyes is basically wasted energy. By creating OLEDs that send out polarized light, the team can get the light from the OLEDs to pass through a polarized filter while light from outside will still get filtered by it.

For now, the technology doesn’t mean much for phones we have in our hands. Since it's still being researched, it's not likely to find its way for upcoming phones very soon. 3.

When it does, it would result in brighter screens and improved energy efficiency. Screens would not use the same amount of energy to produce bright light because none of it would be filtered out. 4.

And, that would mean much longer-lasting batteries for smartphones.

5. For example, smartwatches don't pack large batteries, so any efficiency improvement would have a strong benefit.

A.That means they will use more energy.

B.Plenty of phones already get a full day of life.

C.This technology can be used in other areas as well.

D.But it would finally be applied to consumers’ phones.

E.It can give OLED screens a huge step forward in competition.

F.The new technology can almost double the efficiency of screens.

G.These make it easier to see the light coming from your phone's screen.

One of the biggest social issues in Japan is the increasingly low marriage rate among young people and the small birth rate, which led to an aging and eventually shrinking（萎缩） population. Most young Japanese women simply don’t seem interested in having many children.

Now what began in Japan is happening globally. As David Brooks wrote, birth rate is becoming smaller in much of the world, from Iran — 1.7 births rate per woman — to Russian, where low birth rates connected with high death rates mean the population is already shrinking. And this includes US, which has long had higher birth rates than most developed nations. Aging countries will face the burden of caring for large elderly populations without a larger resource of young workers.

It’s true that global aging is going to present some major challenges. Who will take care of the elderly? Will an older world be less active and slower to change and adapt? It’s all true. Sometimes I worry about a coming generational war over resources, just as I worry about how I will take care of my own parents in their old age, just as I worry about who might take care of me.

But here’s the thing: an older world may have less pressure on the environment. As we all know, the environment is the real victim of overpopulation.

So maybe a world that grows slower and grows older will put less pressure on the environment, and buy us a few more years to ensure our energy use, along with our birthrates, reaches a sustainable（可持续的）level. After all, we’re supposed to get smarter as we got older. Hopefully that holds true for the planet as well.

1.The population issue in Japan was mentioned to ________.

A. show young people’s preference to marriage

B. introduce the topic of global birth rate becoming smaller

C. indicate the deeper cause of Japan’s depression

D. emphasize the revolution of Japanese women

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

A. The birth rates all over the world are becoming smaller.

B. The most developed countries have higher death rates.

C. America is the only developed country with higher birth rate.

D. Birth rate’s becoming smaller means a great risk to aging countries.

3.Which will be caused by low birth rates according to the passage?

A. Aging society. B. Environmental problems.

C. High death rates. D. Low employment rates.

4.What’s the author’s attitude to the worldwide birth rates becoming smaller?

A. Anxious. B. Disappointed.

C. Hopeful. D. Doubtful.

Negative thinking is one of the biggest obstacles(障碍) we face in experiencing happiness, but there's hope. Here are two strategies to help defeat your negative thinking.

1.When you're heading into a social gathering, you begin to wonder what if I don't connect with anyone. Am I even likable? Faced with this situation, do something that lifts your mood.2. For example, listen to a song that makes you smile or take a moment to appreciate people in your life who love you. Positive emotions literally undo the effects of anxiety by lowering our heart rate and muscle tension.

The other is to combat(战斗). 3. But in reality, our minds feed us messages that range from the embellished(渲染的) truth to total lies. Imagine yourself in court. You are the prosecutor(控方律师), and your negative thought is the defendant(被告).4.When he shouts out “You're not good enough at your job”, you need to consult the evidence you have to prove it wrong, argue back with the strongest piece of evidence you can find. Always remember your task is to get the judge to hear your side. So you can say “I am good enough because every performance review I've had has been positive. And my boss told me last week how much she enjoyed working with me. “In a nutshell, bring your best version of a tough lawyer to that courtroom. Convince the judge that the negative thought doesn't deserve attention.

Both of these strategies, to distract and combat, are skills anyone can learn and get better at with practice.5.

A.He's guilty, but he insists that he's not guilty and sticks to his story.

B.Therefore, negative thinking is one of the biggest problems lots of us suffer from.

C.Remember, with each negative thought you defeat, you’ve successfully earned your own happiness.

D.That is, generate a positive emotion.

E.We often believe that our negative thinking is true.

F.There's simply no point focusing on the negative aspect of everything.

G.One is to distract.

One of the biggest complaints in modern society is being over-scheduled. Ask people how they are and the answer usually is “super busy,” “crazy busy” . _______ is just “fine” any more.

It could　 be because human beings,　 as problem solvers and　 meaning makers, when _______, tend to　　 think about what’s wrong in their lives. When we aren’t _______ our Facebook page, the things we haven’t　 figured out appear in our minds—_______ relationships, professional failures, health concerns, etc. Unless　　 there is a solution, these thoughts just ________ themselves in our heads.

But you can’t solve problems ________ you don’t allow yourself time to　 think about them. It has　　　 actually been ________ by our culture, which values doing more than thinking and believes answers are in　　　 your hand ________ in your head. “We　 all fell that busyness　 is ________ but it’s really harmful,”　 said　　　 Timothy. “There’s a widespread belief that thinking will only slow you down and get ________, but it’s the opposite.” ________ negative feelings only makes them more powerful, he said. Allowing and ________ the　 flow of thoughts is part of the solution itself, such as meditation(冥想).

Negative feelings are sometimes hard, but they are part of everyone’s life, ________ if you are busy. It is those deep　 and troubling feelings,　 and how you ________ them, that make you who　 you are. While　　 busyness may seem to prevent the flow of sadness, it may also limit your ability to be filled with ________.
