Taking a math test can be pretty stressful. Even if you know the material, you can still get the problem wrong. {#blank#}1{#/blank#} Therefore you'll improve your grades, as well as your math skills.

    Write it out

    You can also check a math problem by writing everything out on paper. {#blank#}2{#/blank#} Writing out math problems reduces your chances of missing anything to the lowest possible level, which is a common cause of incorrect answers.

    {#blank#}3{#/blank#}

    Make sure your answers work by doing the opposite procedure of what your problem calls for, including the answer you got the first time around. In other words, you would use the opposite of this addition problem—subtraction (减法)—to determine whether your answer is the correct one.

    Plug in（代入）

    You may find that a variable isn't good enough or have a problem where you have to solve for a variable (变量). {#blank#}4{#/blank#} This is the only real way to assure yourself that the answer you've found is correct.

    {#blank#}5{#/blank#}

    If the result of a problem seems to make no sense, it indicates that the answer is incorrect. For example, if you get an answer in the millions and you know it should be in the thousands, you've likely misplaced a point. Go back through the work on your paper to make sure all of your formulas and calculations are correct. If everything looks okay, do the problem again and compare the result of the second try to what you've got on the first try.

A. Do the opposite.

B. Correct the answers.

C. Plug the variable in the equation (方程) to check it out.

E. It also helps you to figure out everything after you have already finished the test.

F. Check for a reasonable answer

G. This helps you to know what information you have and what information you need to solve.

    Be reliable. If you and your friend agree to meet somewhere, don't be late. If you're not going to make it on time or make it at all, call them as soon as you realize it. {#blank#}3{#/blank#} Be someone that people know they can depend on.

    {#blank#}4{#/blank#} Listen carefully to what people say, remember important details about them （their names, their likes and dislikes）, ask questions about their interests, and just take the time to learn more about them.

    Earth is home to around 7,000 languages, around half of which are expected to disappear by 2100.

    Languages disappear for many reasons. Sometimes younger generations stop learning a language because parents want children to fit in. {#blank#}1{#/blank#} Native American children of the late-19th century were required to attend boarding schools where educators forbade them from speaking their native languages.

    The United Nations ranks endangered languages according to their risk level. For example, a "critically endangered" language is one that even grandparents don't speak often. New York's Onondaga language is an example with only 50 speakers left. An "extinct" language has no speakers. It is gone forever. Alaska's Eyak language is one example. {#blank#}2{#/blank#}

    {#blank#}3{#/blank#}In the same way, different languages contribute to cultural diversity. Saving these languages benefits our understanding of other cultures. Languages can show how a society looks at the world and what it values. A language may describe something in a way that is funny, too. In Welsh, it rains not cats and dogs, but old wives and walking sticks.

    The Endangered Language Alliance wants to save languages from disappearing. {#blank#}4{#/blank#} However, its efforts are limited. If an endangered language is going to make a real comeback, it'll probably get its start in schools. For nearly 100 years, public schools in Hawaii did not teach the Hawaiian language. Now students can keep learning in Hawaiian from elementary schools to college and beyond.

    {#blank#}5{#/blank#} At least one did. In 1881, a Jewish linguist named Eliezer Ben-Yehuda brought the 3,000-year-old language Hebrew back to life. Today it is one of the official languages of the country of Israel, with more than 4 million speakers.

A. The last person who spoke it died in 2008.

B. Why should we save endangered languages?

C. Various animals and plants benefit our environment.

D. With just 5 speakers left, it is absolutely endangered.

E. Can a language with zero native speakers come back to life?

F. Sometimes societies force minorities to give up their language.

G. The nonprofit group finds native speakers and records their stories.

    What to Do When Someone Doesn't Like You

    When someone tells me, “I don't care if people like me,” they are showing me the emotional wall they use to block the hurt of rejection.

    As humans are social animals, all of us care if people like us. Based on the need for social connection, your reactions to rejection and negative judgment can range from minor hurt to breakouts of depression. {#blank#}1{#/blank#}

    The first step to handle a negative situation is to recognize your reaction. Ask yourself, “What am I feeling?”. {#blank#}2{#/blank#}Any betrayal (背叛) or embarrassments in your heart? Identify what feeling has shown up in your body? So you can choose what to do next.

    {#blank#}3{#/blank#}When you sense yourself shutting down or feeling defensive, ask yourself what the person actually meant to do to you. Did they truly mean to offend you, or make fun of you? Your brain works very hard to keep you safe, so it will judge a situation as threatening if there is any possibility of social harm.

    When our brains sense a possible threat, we react as if we were personally attacked. Take a breath to relieve the stress, {#blank#}4{#/blank#}

    Finally, if you believe the person doesn't like you, ask yourself if this matters. {#blank#}5{#/blank#}If not, what can you do to release your need to be liked by this person? And, what can you do to stay neutral and not return the dislike? The more you can come to accept others as who they are , the more you can move forward with your goals regardless if someone likes you or not.

A. If you can, look the person in their eyes.

B. Do you feel any fear or anger in your head?

C. Ask yourself what is true about the situation.

D. Often people do not realize the impact of their words.

E. Will the person's judgment of you impact your work or life?

F. The ability to let a show of dislike roll off your back is a learned skill.

G. This will ground you in the present and take you out of your trembling mind.
