    The key to dealing with test-day jitters（焦躁）is through preparation! {#blank#}1{#/blank#} It is important to prepare your mind and body before the test for the experience of working under pressure.

    Get some sleep.

    I know you've heard this before, but it's often repeated because it's so important. Get plenty of sleep the night before the test! If you don't have enough rest, you'll end up with less concentration. {#blank#}2{#/blank#}

    Leave early.

    Be sure to leave earlier than normal on the day of a test to avoid the added fear of arriving late. {#blank#}3{#/blank#} The embarrassment will cause you to be distracted and lose valuable time.

    {#blank#}4{#/blank#}

    Once you arrive at school or at the testing center, find a quiet space where you can be all alone. You can use your car if you drive, or you can find an empty locker room or office (ask a teacher). Once you locate a cozy nest in a quiet place, do a relaxation session (=period). Close your eyes and try to relax completely. Take deep breaths and remain calm.

    It's possible that some students start to stress out as other students discuss the material. When you hear others chatting, it might sound like you ignored something important or you misunderstood a concept (概念). It's probably not even true—but it can seem like it!

A. Take a quiet moment.

B. A sleepy brain is a foggy brain.

C. Watch out for chatting with others after a test.

D. Attending an exam late is the last thing you need.

E. You can find time to eat some snacks during a break.

F. Don't talk with other students in the minutes before a test.

G. But full preparation means more than knowing the test material.

    Some people think working overtime means you're a hard worker. You have to sacrifice your personal time to stay at work, produce something, help the company, and be a more devoted employee. But is that right? {#blank#}1{#/blank#} This means it takes you longer to produce something than someone else.

    A good manager knows how to encourage his employees to work to their full potential instead of expecting them to work late even if they don't have something to do. People who stay in their office until late hate their jobs. {#blank#}2{#/blank#}

    Overworking may negatively influence the level of productivity and efficiency (效率). Any company that makes their employees work those hours is not being managed well. The fault lies with management, who should take a good look at themselves. {#blank#}3{#/blank#} And the boss would prefer you work efficiently 7 hours and then go back home than 8 hours with poor efficiency.

    {#blank#}4{#/blank#} The fact is the competition is so fierce that if you don't work hard someone will easily and willingly replace you, especially in the IT industry. Employees are told they need to work longer hours or they don't belong or are denied promotions. It is time to abandon the culture of overworking, to work smarter, more efficiently and have a balance with personal life.

    Nowadays, it's hard for a young person to build a good future, for pressures are on his (or her) shoulders: housing, children, parents, themselves, etc. But everyone must keep working hard to have ourselves on the way to the good future, which is not certain. {#blank#}5{#/blank#}

When you were at school, were you ever told to stop daydreaming and concentrate? It was easy for your mind to wander if you weren't interested in what you were learning or if you had better things to think about. {#blank#}1{#/blank#} But understanding how to do it, and knowing what is distracting you, can help.

Scientists have looked at what makes us delay and found a number of ways to help us stay in the zone. {#blank#}2{#/blank#} Research by Science Focus magazine found silence is best for concentration, or a gentle background music is great! It also found turning off notifications on your phone, or switching it off altogether, removes a major distraction and helps us focus on the task at hand.

  {#blank#}3{#/blank#} Psychologists and neuroscientists are increasingly interested in our ability to settle down and have looked at what we can change inside our head to make us concentrate. An article for BBC Future by Caroline Williams says that "Attention Researcher Nilli Lavie of University College London has found that making a task more visually demanding takes up more processing power and leaves the brain nothing left to process distractions." So, keeping your mind busy might be the answer.

 {#blank#}4{#/blank#} These include making a list or timetable of the tasks you have to do, finding a workspace where you're not attracted by other things, or chewing some gum! It's possible the movement in your mouth occupies parts of the brain that might otherwise get distracted.

But according to Science Focus magazine, distraction isn't all bad. "If we were always so focused that we never got distracted, we'd miss potential changes, such as threats, in our environment. {#blank#}5{#/blank#} ."

A. Distraction is vital for survival.

B. Staying focused can avoid dangers.

C. Performing visual tasks makes us concentrate.

D. One of the most obvious things is removing noise.

E. Staying focused can still be a challenge in adult life.

F. There are more practical tips to keeping your mind focused.

G. Another possible cure for a short attention duration is brain training.
