注意事项:

第二卷用碳素笔直接答在答卷纸上。

答卷前将密封线内的项目填写清楚。

第四部分:书面表达(共两节,满分45分)

第一节   阅读表达:

阅读下面的短文,并根据短文后的要求答题(请注意问题后的词数要求。答案写在答卷纸上)

Learning to save money when you're young is an important lesson. All good lessons and habits begin early, and saving is a skill that everyone needs. Many people—adults included—do not have a good sense of saving for the long run.

I have been lucky to learn this lesson early because I have had a grass-cutting business since I was 10 years old. Of the money I make I spend about 10 percent and save the other 90.

Making sure you save and don't spend too much is a good way to build up wealth. I have put my earnings in a bank. Many teens I know spend all the money they earn so it never has a chance to grow. Young people should realize that their teenage years are a great time to begin saving.

At high school many parents pay for almost everything, so your expenses can be small. If you have a job, you should have fun with some of the money. But you should also save some so that it will grow. Then you can begin planning for your future. When you spend money, you not only lose that money, but also lose the interest you could have earned by saving it.

After high school, college is expensive and then "real" life begins, with expenses such as food and rent. If you can hold onto a good percentage of the money you earn as a teen, going to college and buying a house will be much easier. ________________, the more time the money has to grow. If you are in your thirties without any savings, you will always have to struggle. The earlier you begin saving, the easier it is to create a nest egg.

Later in life it can be hard to start saving because general costs of living are more expensive and you may only have enough to pay your bills. If you want to buy a house and have a family, you need money to start with, which comes from saving.

Many say money cannot make you happy, and this is true. But money can help you to lead a secure life.

Saving early will mean you will have to work for fewer years when you are older. It will also allow you to spend time doing the things that you want to do.

In addition to this, it will mean you can live the way you want to without worrying. 

76. What’s the best title of the passage?

_______________________________________________________________________________

77. Which sentence in the passage is the closest in meaning to the following one?

As long as you save early, you’ll do less work to live well at your old age.

_______________________________________________________________________________                                                                         

78. Please fill in the blank in the passage with proper words or phrases to complete the sentence.(within 10 words)

_______________________________________________________________________________                                                                      

79.  According to the passage, what do you think of saving? (within 30 words)

___________________________________________________________________________

80. Translate the underlined sentence into Chinese.

At 7:30 on the morning, we gathered at the school gate and set off on a large bus. An hour later, we arrive at the Forest Park. Getting off, we started our journey at once.

First, we climbed the green hills and on the way tried their luck to hunt for hidden treasure. Next, we toured around the lake in the comfortable boat. The beautiful scenery was really a feast for the eye. Then at noon time, we landed and settled at an open area, which we enjoyed a wonderful picnic. After eating, we sang and danced happy and played some interesting games. The day passed quickly. Finally it was time for us to return back. So at 3:00 pm, we cleaned the ground, made our way to the parking lot, getting on the bus and left.

It was really an exciting trip since we had long busy with our school work.
