陕西省渭南中学2018-2019学年高二上学期英语第三次月考试卷
Of all the things we eat and drink, water is the most important. Not all people realize this, but it is quite true. The human body can live without food for a long time, but two or three days without water usually result in death.
Many people do not understand how much water the human body needs, but many people do not drink enough, especially in the hot weather. Most people drink when they are thirsty but often need more water after exercises.
65 to 70 percent of the human body is water. Water is important in several different ways. Most people need five to seven litres of water every day, but we need not drink this amount because a lot comes from the food we have. If we don't have enough water, however, we will feel tired and many become ill. Do you know what the best drink is? Yes, you are right. Cold water!
Taking a math test can be pretty stressful. Even if you know the material, you can still get the problem wrong. Knowing how to go through your math test and check your work can save you from handing in a test full of mistakes that can be avoided. {#blank#}1{#/blank#}
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 or not your answer is the correct one.
Plugging in
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.
Check for a reasonable answer
{#blank#}5{#/blank#} 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. Therefore you'll improve your grades, as well as your math skills. E. It also helps you to figure out everything after you have already finished the test. F. If the result of a problem seems to make no sense, it indicates that the answer is incorrect. G. This helps you to know what information you have and what information you need to solve. |
