题目内容

Taking a math test can be pretty stressful. Even if you know the material, you can still get the problem wrong. 1. 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. 2. Writing out math problems reduces your chances of missing anything to the lowest possible level, which is a common cause of incorrect answers.

3.

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

5.

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.

The youngest of five children in a middle-class family, Clara Barton was born on Christmas Day, in 1821, in Oxford, Massachusetts. Although she was educated at home, Clara began teaching school herself at the age of fifteen until 1854. Later, before the Civil War (内战), Clara’s greatest achievement was the establishment (建立) of a free public school in Bordentown, New Jersey. What’s more, her only medical experience was when she cared for her invalid (病弱者) brother for two years.

When the Civil War broke out, Clara soon learned that many of the wounded soldiers had suffered from lack of medical supplies. So she asked for donations (捐款) to buy those supplies and began her own operation to hand out these supplies. In 1865, Clara built an information centre to serve war-torn families and often gave speeches. With so much work, she fell ill in 1868 and went to Switzerland to recover, where she learned something about the International Red Cross founded in 1864. But the United States could not take part then. Barton, returned home and began to establish the Red Cross in America. She worked hard, travelling to Washington for support, gave speeches and wrote articles to win the support of the public. She told people the Red Cross was not only important during times of war, but also useful in peace time. This got the attention of both the public and the politicians, and thus the American Association of the Red Cross came into being in 1881.

A. Advise the government to buy more medical supplies.

B. Help some families to rebuild their home.

C. Collect money to buy medical supplies.

Minutes after the last movie ended yesterday at the Plaza Theater, employees were busy sweeping up popcorns and gathering coke cups. It was a scene that had been repeated many times in the theater’s 75-year history. This time, however, the cleanup was a little different. As one group of workers carried out the rubbish, another group began removing seats and other theater equipment in preparation for the building’s end.

The film classic The Last Picture Show was the last movie shown in the old theater. Though the movie is 30 years old, most of the 250 seats were filled with teary-eyed audience wanting to say good-be to the old building. Theater owner Ed Bradford said he chose the movie because it seemed appropriate. The movie is set in a small town where the only movie theater is preparing to close down.

Bradford said that large modern theaters in the city made it impossible for the Plaza to compete. He added that the theater’s location(位置) was also a reason. “This used to be the center of town,” he said. “Now the area is mostly office buildings and warehouses.”

Last week some city officials suggested the city might be interested in turning the old theater into a museum and public meeting place. However, these plans were abandoned because of financial problems. Bradford sold the building and land to a local development firm, which plans to build a shopping complex on the land where the theater is located.

The theater audience said good-by as Bradford locked the doors for the last time. After 75 years the Plaza Theater has shown its last movie. The theater will be missed.

1. In what way was yesterday’s cleanup at the Plaza special?

A. It made room for new equipment.

B. It signaled the closedown of the theater.

C. It was done with the help of the audience.

D. It marked the 75th anniversary of the theater.

2. Why was The Last Picture Show put on?

A. It was an all-time classic. B. It was about the history of the town.

C. The audience requested it. D. The theater owner found it suitable.

3.What will probably happen to the building?

A. It will be repaired. B. It will be turned into a museum.

C. It will be knocked down. D. It will be sold to the city government.

4.What can we infer about the audience?

A. They are disappointed with Bradford. B. They are sad to part with the old theater.

C. They are supportive of the city officials. D. They are eager to have a shopping center.
