Taking a math test can be pretty stressful. Even if you know the material, you can still get the problem wrong. 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. Writing out math problems reduces your chances of missing anything to the lowest possible level, which is a common cause of incorrect answers.

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). This is the only real way to assure yourself that the answer you've found is correct.

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.
D. Knowing how to go through your math test and checking your work can save you from handing in a test full of mistakes.
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.

【答案】D;G;A;C;F
【解析】本文介绍在进行数学考试时,如何浏览试卷以及检查,从而减少错误,提高成绩和数学技能。
(1)根据后句Therefore you'll improve your grades, as well as your math skills.,可知前面提到怎样帮你提高分数,再根据第2句Even if you know the material, you can still get the problem wrong.,可以推断技能很重要,所以D符合题意。
(2)从前面的句子;You can also check a math problem by writing everything out on paper.可知这样做可以让你知道自己有什么信息,需要解决什么信息。选G
(3)从后面的句子:Make sure your answers work by doing the opposite procedure of what your problem calls for, 说明我们可以反过来做题目。选A
(4)从前面的句子:You may find that a variable isn't good enough or have a problem where you have to solve for a variable (变量). 可知是在方程式中带入变量来检查。选C
(5)根据后句If the result of a problem seems to make no sense, it indicates that the answer is incorrect.,以及if you get an answer in the millions,等可知这段的主题与寻找答案有关,所以F符合题意。

【题目】Distance runners often worry about “hitting the wall” during training or races,when negative thoughts become so overpowering that they make it difficult to continue.1 At that time,the body’s glycogen(糖原) supplies become exhausted.As a result,many runners feel exhausted and discouraged,slow their pace,have trouble focusing and want to quit or walk.2 Here are a few sports psychologist-approved techniques to try,which could have major benefits for an athlete’s performance and well-being.

1.Make a motivational song list.Distracting(分心) yourself with some great tunes can help you make it to the finish line faster.3

2.Try the partner system.A running partner can keep you motivated and on-track,and might even improve your performance,research shows.

3.4 A study on weight-lifters found that mental practices can be as effective as physical practice,resulting in actual muscle increases.Visualizing your if-then plan,for instance,could improve your chance of success.

4.Try “attention narrowing”.5 Last year,an NYU study found that focusing on an object on the horizon makes the distance feel shorter,and leads runners to go faster and perform better than those who let their minds wander.

With these helpful strategies,your next personal record might be just around the corner.

A.Plan what to do.

B.Visualize achieving your goal.

C.Finding ways to move past those kinds of experiences is very vital.

D.“Hitting the wall” typically happens around 20 miles into a marathon.

E.There is evidence that saying motivational things to oneself benefits a lot.

F.Runners who focus their eyes on an object in the distance get there faster.

G.Studies show athletes run,bike and swim farther and faster when listening to music.

Choosing the right job is probably one of the most important decisions we have to make in life, and it is frequently one of the hardest decisions we have to make. One important question that you might ask yourself is: “How do I get a good job?”
. There are people who can answer an insignificant advertisement in the local paper and land the best job in the world; others write to all sorts of places all over the country, and never seem to get a reply at all. Still others believe that the in person, door-to-door approach is by far the best way to get a job; and then there are those who, through no active decision of their own, just seem to be in the right place at the right time. . He used to spend a lot of his free time down by the sea watching the tall ships, but never thinking that he might one day sail one of them. His father was a farmer, and being a sailor could never be anything for the boy but an idle dream. One day, on his usual wandering, he heard the captain of the ship complaining that he could not sail because one member of his crew was sick. Without stopping to think, the lad(少年)offered to take his place.
. If the lad had gone home to ponder(考虑) his decision for a week, he may have missed his chance. It is one thing to be offered an opportunity; it is another thing to take it and use it well. Sometimes we hear stories about people who break all the rules and still seem to land plum jobs(美差). When you go for a job interview or fill out an application, you are expected to say nice things about the company to which you are applying. . And within a year this person had become general manager of the company.
A. This story also illustrates the importance of seizing an opportunity when it presents itself.
B. People find jobs in a variety of ways.
C. It's almost impossible to find a good job by answering advertisement in newspapers
D. Take for example the young man who wanted to be a sailor.
E. But there was one person who landed an excellent job by telling the interviewer all the company's faults.
F. He spent the rest of his life happily sailing the ships he had always loved.
G. It is very important to seize an opportunity when it presents itself.
