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.   66 

Write it out

   You can also check a math problem by writing everything out on paper.   67   Writing out math problems reduces your chances of missing anything to the lowest possible level, which is a common cause of incorrect answers.

 68 

 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(变量) isn’t good enough or have a problem where you have to solve for a variable.   69   This is the only real way to assure yourself that the answer you’ve found is correct.

Check for a reasonable answer

       70   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.

The principles about applying for jobs have altered greatly lately. In the past, people preferred a hand-written application letter．However, nowadays it is becoming more and more common to apply for a job through the Internet．You can find information on the Internet about how to apply for jobs．Information can be found about how to fulfill your application letter, the clothes that you should wear and how to carry out the interview itself．
The importance of body language is often mentioned，but doesn’t always get the attention it deserves．After all，before a word has even been spoken，your body language will have already given people their first impression of you．Additionally, your body language will also give out a lot more information．Based on your body language it can be seen if you are self-confident．It can also show if you are a busy or a quiet type and it helps give an impression of whether you are speaking truthfully or not．Body language can show how enthusiastic you are and if you are a nice person．someone who will take his work seriously, but also someone who has a sense of humor and can enjoy a joke from time to time．The members of the application committee will ask you questions，but your answers won’t only be oral．The committee will not only pay attention to what you say, but also to how you say it! Body language will determine first if it ‘clicks’，and sometimes all it takes is just a few seconds．Everybody uses body language，but it takes place mostly at a subconscious（下意识的） level．Using body language appropriately, you can definitely increase your chances of getting a job．
【小题1】What kind of people is the text mainly meant for?

BEIJING, China (CNN)-- China's economic growth dropped to 9 percent for 2008, according to numbers released by the government Thursday--in line with expectations, but still the slowest rate the nation has seen in seven years.

Economists are concerned about what the slowdown means for investment in the future, whether new projects will be undertaken in manufacturing companies and in factories. If not, it will translate into more job losses and erase any optimism about a rebound (反弹) in 2009.

Since 2001, China has been used to double-digit growth as consumers buy Chinese goods. However, the export sector was hit hard in late 2008, with December exports down 2.8 percent.

Consumer spending has mostly held up in China, as people there do not carry as much debt as their American counterparts and can continue to spend.

Consumer confidence, however, is a problem, said Dong Tao, Asia chief economist for Credit Suisse. Infrastructure (基础设施的建设) is the only thing driving the Chinese economy, Dong said.

Tens of thousands of Chinese factories have closed, millions of people are looking for jobs and an untold number of migrants who can't find work may be leaving cities for good because of the slowdown, which would have been unheard of six months ago.

Fourth quarter numbers showed growth at 6.8 percent. Goldman Sachs predicted 6.5 percent, down from 9 percent in the third quarter.

For all of 2008, Goldman Sachs had predicted 8.8 percent, down from 11.9 percent in 2007.

1. Since 2001, the slowest rate in annual economic growth China has seen is ___.

    A. 6.8%    B. 8.8%    C. 9%    D. 11.9%

2. According to Dong Tao, the only thing driving the Chinese economy is ____.

    A. export    B. infrastructure    C. consumer confidence   D. consumer spending

3. Which of the following is NOT the difficulty China is facing?

    A. Tens of thousands of factories have closed.

    B. Millions of people are looking for jobs.

    C. An uncertain number of migrant workers may be leaving cities forever.

    D. The terrible situation will erase any optimism about a rebound in 2009.

4. In which quarter of 2008 did the slowdown of China's economic growth first appear?

    A. 1st.    B. 2nd.    C. 3rd.    D. 4th.

5. The best title of this passage should be _____.

    A. China's Economic Growth Slows.

    B. Economic Crisis in China.

    C. Economists Analyze China's Economy.

    D. Several Factors Determine China's Economy

第三部分 阅读理解（共20小题：每小题2.5分，满分50分）
阅读下列短文，从每题所给的四个选项A、B、C、D四个选项中，选出最佳选项。
Today, as in every other day of the year, more than 3000 U.S. adolescents will smoke their first cigarette on their way to becoming regular smokers as adults. During their lifetime, it can be expected that of these 3000 about 23 will be murdered, 30 will die in traffic accidents, and nearly 750 will be killed by a smoking-related disease. The number of deaths attributed to cigarette smoking outweighs all other factors, whether voluntary or involuntary, as a cause of death.
Since the late 1970s, when daily smoking among high school seniors reached 30 percent, smoking rates among youth have declined. While the decline is impressive, several important issues must be raised.
First, in the past several years, smoking rates among youth have declined very little. Second, in the late 1970s, smoking among male high school seniors exceeded that among female by nearly 10 percent. The statistic is reversing. Third, several recent studies have indicated high school dropouts have excessively high smoking rates, as much as 75 percent.
Finally, though significant declines in adolescent smoking have occurred in the past decade, no definite reasons for the decline exist. Within this context, the National Cancer Institute (NCI) began its current effort to determine the most effective measures to reduce smoking levels among youth.
36. According to the author, the deaths among youth are mainly caused by __________.
A. traffic accidents                                   B. smoking-related disease
C. murder                                                 D. all of these
37. Every day there are over ______ high school students who will become regular smokers.
A. 750                         B. 23                    C. 30                    D. 3000
38. By “dropout” the author means __________.
A. students who failed the examination        B. students who left school
C. students who lost their way                    D. students who were driven out of school
39. The reason for declining adolescent smoking is that __________.
A. NCI has taken effective measures           
B. smoking is prevented among high school seniors
C. there are many smokers who have died of cancer          
D. none of these
40. What is implied but not stated by the author is that __________.
A. smoking rates among youth have declined very little     
B. there are now more female than male smokers among high school seniors
C. high smoking rates are due to the increase in wealth
D. smoking at high school is from low socio-economic backgrounds
