Humans use electricity to light up the night sky. But did you know that nature itself can glow, too?

    {#blank#}1{#/blank#}. Some use their lights to communicate. Others shine to hunt, to mate or to protect themselves. The vampire squid, for example, gives out a cloud of light to scare enemies.

    {#blank#}2{#/blank#}.

    In 2013, the US company Gleaux said it had created the world's first light-producing plant, reported the Daily Mail.

    {#blank#}3{#/blank#}.

    “People have dreamed about this stuff for many years,” said Alexander Krichevsky, the company's founder.

    He and other researchers are working toward a future in which glowing plants replace lamps and glowing trees line highways.{#blank#}4{#/blank#}, making them glow to let farmers know when they need water or are ready to be picked.

    While GleauX is working on glowing plants, the French company Glowee is trying to use glowing bacteria to light up shop windows and street signs. It is the same type of bacteria that causes certain sea animals to light up.

    {#blank#}5{#/blank#}.The company is now working on a light that shines brighter, lasts longer and comes in different colors.

    “Our goal is to change the way we produce and use light,” said Glowee founder Sandra Rey. “We want to offer a global solution that will reduce the 19 percent of electricity consumption used to produce light.”

A. People are also creating glowing bacterial art that you can hang in your home

B. Scientists have found many glowing creatures, most of which live in the ocean

C. Krichevsky also hopes the technology could be used in crops

D. Researchers around the world are looking into nature's lights for new ideas

E. It is a genetically-modified plant that glows like fireflies do

F. In 2016, Glowee created a bacteria-powered light that glows for three days

G. This technology could help us save much energy

    Good learners can inspire students or anybody to learn well. Here are some characteristics of good learners.

    Good learners are curious. They wonder about all sorts of things, often about knowledge beyond their areas of expertise(专长). {#blank#}1{#/blank#} Finding out about something they didn't know satisfies them for the moment, but their curiosity is addictive.

    Good learners don't give up easily. A few things may come easily to learners but most knowledge arrives after effort. {#blank#}2{#/blank#} They try to search out new information. They read, analyze, and evaluate the information they've found. Then they study more and work at what they don't understand.

    Good learners know that a lot of learning isn't fun. The journey to understanding generally isn't all that exciting. {#blank#}3{#/blank#} Others need a tiresome attention to detail, and still others need periods of intense mental focus. Your backs hurt, your arms and legs get tired, and your coffee gets cold.

    {#blank#}4{#/blank#}There's always more to know. Good learners are never satisfied with how much they know about anything. They are pulled around by questions—the ones they still can't answer, or the ones without very good answers. Those questions follow them like day follows night with the answers bringing daylight.

    Good learners share what they've learned. Good learners are teachers committed to sharing with others what they've learned. {#blank#}5{#/blank#} Good learners can also explain what they know in ways that make sense to others. They are connected to the knowledge passed on to them and committed to leaving what they've learned with others.

A. Some learning tasks require boring repetition.

B. Good learners are willing to put in the time.

C. Some knowledge can broaden our views.

D. Good learners stay positive.

E. They write about it, and talk about it.

F. They love the discovery part of learning.

G. Good learners never run out of questions.

    A global cyberattack, which is considered the biggest cyberattack ever, is spreading quickly and widely.{#blank#}1{#/blank#}

    What the attack does

    Cyber bad guys have spread ransomware(勒索软件), known as WannaCry, to computers around the world. It locks down all the files on an infected computer. The hackers then demand $300 in order to release control of the files.{#blank#}2{#/blank#}

    How it happened

    WannaCry takes advantage of a vulnerability(弱点) in Microsoft Windows. Microsoft released a security patch for the vulnerabilities in Marclf. {#blank#}3{#/blank#} Playing with fire finally caught up with the victims.

    Microsoft requires Windows 10 customers to automatically update their computers, but some people with older PCs disabled automatic updates.

    {#blank#}4{#/blank#}

    The attack has been found in 150 countries, affecting 200,000 computers, according to Europol, the European law enforcement agency. FedEx, Nissan, and the United Kingdom's National Health Service were among the victims. In the U.K., hospitals were crippled by the cyberattack, which forced operations to be canceled and ambulances to be diverted.

    Who is vulnerable

    {#blank#}5{#/blank#}Microsoft said it had taken the "highly unusual step" of releasing a patch for computers running older operating systems including Windows XP, Windows 8 and Windows Server 2003. So even people with older computers should update them.

    Apple's Mac computers were not targeted by this ransomware attack. Bad guys generally target Windows far more than Apple's operating system because there are vastly more computers running Windows around the world.

A. When it will be solved

B. How widespread the damage is

C. That's why it's called ransomware.

D. The hackers remain anonymous for now.

E. Here is a super-simple explanation of what's going on.

F. Anyone who hasn't updated their windows PC recently is easy to attack.

G. But many corporations don't automatically update their systems.

    It is important that you teach your baby to read as young as possible. Why? Because there is simply no better time in a child's life for learning than when they are between 3 months old and their 5th birthday.{#blank#}1{#/blank#}

    As a result, they are sponges(海绵)for knowledge. Moreover, being able to read is the basis for any successful education, so the earlier they start, the better. All too often, parents leave educating their children up to schools, which probably explains why the United States is currently ranked 18th in its rate of reading and writing.

    Teaching your baby to read provides brain exercise during the very time when his or her brain is developing. It has also been shown to increase the baby's IQ. The sooner they begin to read, the sooner they can begin to learn other subjects. This way, by the time your children begin school, they will already know what's being taught, and will be put on the fast track. {#blank#}2{#/blank#}

    One of the cases that really began to bring the fact that babies can learn to read to the public's attention was 17-month-old Elizabeth Barrett. {#blank#}3{#/blank#}

    She was given a series of words and even sentences that she could read quite well. Her parents had been reading to her since she was born and had provided her with a very early education.

    Reading is the most important thing to teach babies at a young age. {#blank#}4{#/blank#}Learning can be fun at such an early age, and it can be accomplished so easily that they won't have to struggle in order to learn. In fact, when you use the proper materials, they will look forward to learning.

    If you're interested in teaching your baby to read, the best way to start is by spending just a few minutes a day. {#blank#}5{#/blank#}

    Simply show your baby matching pictures on the opposite side. There are also videos that help to teach babies to read.

    There is no better time to teach your baby to read than the present. Begin by looking for learning materials that your baby might enjoy.

A. Flash cards are an effective tool.

B. She appeared on the Today show.

C. Maybe they will even skip a grade down the road.

D. During this time, their brains are developing rapidly.

E. What's more, your child will be able to read so successfully.

F. It doesn't have to be stressful or difficult for your child though.

G. Parents talk about the pride that their children can read at an early age.

We know that choosing a college major can be stressful.{#blank#}1{#/blank#}! Here's what you need to know about college majors before you commit.

Career prep

Choose a major because it will prepare you for a specific career path or advanced study. Maybe you already know that you want to be a nurse, a physical therapist, or a web developer.

{#blank#}2{#/blank#}. Make sure you're ready for the coursework required for the career of your dreams.

Earning potential

Future earning potential is worth considering. After all, college is such a big investment. The majors that lead to the highest salaries include just about any type of engineering, mathematics, computer science, and economics. {#blank#}3{#/blank#}. That six figure salary may not be worth it if you're not happy at the office.

{#blank#}4{#/blank#}

Some students choose a major simply because they love the subject matter. If your love is philosophy, don't write it off just because you're not sure about what the job market holds for philosophers. Many liberal arts majors provide students with critical thinking skills and writing abilities that are highly valued by employers.

Explore your interests

If you truly have no idea what you want to study, that's okay.{#blank#}5{#/blank#}. That gives you four semesters to play the field. Make the most of any required general education courses—choose ones that interest you. Exploring your interests will help you find your best fit major—and maybe even your ideal career.

A. Many schools don't require students to declare a major until the second year

B. The most exciting aspects of college life is that it fosters new passions

C. A double major provides you with an understanding of two academic fields

D. However, keep your quality of life in mind, too

E. But have no fear

F. Before you decide, check out the curricula

G. Subjects you love

A budget is your plan for how you spend your money. Saving money isn't easy unless you have a plan and stick to it. {#blank#}1{#/blank#}.

Set Savings Goals

Defining a goal for your savings plan is the very first step. The Consumer Financial Protection Bureau (CFPB) promotes using SMART savings goals: specific, measurable, attainable, relevant and tailored. {#blank#}2{#/blank#}. By setting SMART financial goals that are a good fit for your personal finances, you are more likely to keep up with the plan and succeed.

{#blank#}3{#/blank#}

Overspending is scary for many savers and spenders, but getting weekly spending down on paper can be enlightening and uncover opportunities to save an amount of money right away. Check out the CFPB's spending tracker that automatically sums expense categories and highlights spending limits, helping you stay in control of your money.

Evaluate and Cut Down Monthly Bills

{#blank#}4{#/blank#}. But you may be able to reduce some of the bills. Look for ways to upgrade to energy-efficient appliances if your budget allows. Subscriptions and streaming services are other areas that hide monthly expenses.

Make a Budget and Use Technology

Once you've reduced expenses and identified your savings goal, a budget is key to start saving. {#blank#}5{#/blank#}. If you find yourself getting hit with late payment fees or insufficient funds on your checking account, it's definitely time to address this with technology. Not only do these fees burn lots of money when you're trying to save it, but they can also hit your credit report and impact your credit score.

A. Track Spending Habits

B. Identify and Change Spending Habits 

C. The savings goals you set must be in line with your financial situation

D. Apps and online banking working together make it easier to set up ways to save

E. There are some expenses you can't get around: shelter, food, health care and insurance

F. Setting savings goals and conducting an honest review of spending habits are significant

G. Visit your credit card's website to ensure you take advantage of available cash-back offers
