While I was in 9 th grade, I built a circuit (電路裝置) for the traffic system of our city. After getting the first prize. I got this valuable advice from my father; “Do whatever interests you, and don’t let the work challenge you, make sure you are challenging that work.”
I have always preferred the projects which are challenging and related to real life problems. I clearly remember building a shipping program several years ago. I divided the whole project into several small sections. When I understood it clearly, used my brainstorming skill on it, and gave some basic ideas. Then I asked my professor for help before jumping into coding (編碼). At first, I did not know how to ask questions correctly and always asked the question “How do I do it?” As I  kept working and discussed with my professor, I became more comfortable and those “how ”questions soon turned into “what if I do this and that” types of questions.
It took me four days to write the code. The desire to solve the problem kept me sleepless all nights brainstorming in even greater details. Every time I saw my program running smoothly, I exploded with joy. I still remember the last day of my work. I was getting some problem and didn’t know what to do. At that moment, a man came in to clean. He has headphones, and he was dancing while cleaning the room. Seeing this, I burst out laughing. That moment calmed me. I regained energy and interest and started to work again, and soon I fixed the problem.
My success in the project proved that breaking up a large problem into small parts could help find a possible solution. Discussing the problem with others was also very beneficial. Now I have gained the confidence to attempt any kind of project.
59．According to the passage, the writer was interested in          .
A．developing traffic systems
B．doing challenging projects
C．winning great prizes
D．writing different codes
60．The writer asked the question “how do I do it” at first because         .
A．he had no clear idea about his program
B．he was too shy to express himself
C．he wanted to he understood easily
D．he preferred this kind of question
61．We learn from the passage that the writer’s shipping program         .
A．would benefit people a lot
B．was done together with others
C．was difficult and needed patience
D．cost much money and energy
62．What would be the best title of the passage?
A．Do It Yourself
B．No Pains, No Gains
C．Learning with interest
D．Practice Makes Perfect

科目：高中英語 來源：2012屆廣東省六校高三第一次六校聯(lián)考英語試卷 題型：寫作題

閱讀下面的短文，然后按照要求寫一篇150詞左右的英語短文。
In one way of thinking, failure is a part of life. In another way, failure may be a way towards success. The “spider story’’ often told, Robert Bruce, leader of the Scots in the 13 th century, was hiding in a cave from the English. He watched a spider spinning a web. The spider tried to reach across a rough place in the rock. He tried six times without success. On the seventh time he made it and went to spin his web. Bruce is said to have taken heart and to have gone on to defeat the English. Edison, the inventor of the light bulb, made hundreds of models that failed before he found the right way to make one. Abraham Lincoln, the famous American president, lost elections more times than he won them! He never gave up in the face of failure but kept trying and was eventually elected to Congress and then the presidency.
So what? First, always think about your failure. What caused it? Were conditions right? Were you in top from yourself? What can you change so things will go right next time?
Second, is the goal you’re trying to reach the right one? Try to do some thinking about what your real goals may be. Think about this question. “If I do succeed this time, where will it get me?’’ This may help you prevent failure in things you shouldn’t be doing anyway.
The third thing to bear in mind about failure is that it’s part of life. Learn to “l(fā)ive with yourself” even though you may have failed. Remember, “You can’t win them all.”
【寫作內(nèi)容】
1、概括短文的內(nèi)容要點，該部分字?jǐn)?shù)大約30詞左右；
2、以“Is Failure a Bad Thing”為題寫一篇文章，包含以下內(nèi)容要點，該部分的字?jǐn)?shù)大約120詞左右。
⑴失敗是生活中的常事
⑵人們對失敗所持的不同態(tài)度
⑶你對失敗的認(rèn)識
【寫作要求】
1、可以使用實例或其他論述方法支持你的觀點，也可以參照閱讀材料的內(nèi)容，但不要抄襲閱讀材料中的句子
2、作文中不能出現(xiàn)真實姓名和學(xué)校名稱。
