Hello. I’m Jan from Mrs. Lake’s class. My class wants to work together to help the public. We think we have found a great way to do this. Last month we did a class project on the highways near our town. We learned about the Adopt-a-Highway Program. This program brings people together to pick up litter along the roads. We think it would be a great idea for all students in our school to join the program and adopt a highway.

Adopting a highway is not like adopting a pet. When a highway is adopted, only part of the highway is cared for by a group of people. The group agrees to work every week to keep its part of the highway clean. Each group gets its own sign that has the name of the group printed on it. The sign is put up at the side of the road. This sign lets drivers know who is keeping that area of the road clean.

The Adopt-a-Highway Program is a great way for people to help their environment look nicer. Also, the government does not have to send out as many road workers. This saves money. Finally, people may try harder to keep roads clean if they see people, especially teenagers like us, cleaning them up.

We will need helpers to care for our adopted highway. If you want to feel great and keep our roads clean,please come with your parents to the meeting next week. We will meet in Mrs. Lake’ room on Wednesday at 6:00 P. M. At the meeting, we will talk about which roads are the dirtiest as a result of people's unkind acts. Then we''ll try to pick an area to adopt and clean.

I look forward to seeing you at the meeting. Remember to keep our roads clean!

七选五

根据短文内容,从短文后的选项中选出能填入空白处的最佳选项,选项中有两项为多余选项。

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. 1.

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

Check for a reasonable answer

5. 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.
