安徽省蚌埠市2018-2019学年高一下学期英语期末考试试卷
As a college student, I joined a technology and invention group. We chose to focus on studying paint materials for buildings that 1 little or no pollution. At this time, lots of paint 2 harmful materials, for example, formaldehyde (甲醛). We found that some fruits, including apples and pineapples, ave effective materials that could get rid of (去除) those 3.
We did lots of research and experiments, devoting many weekends to 4 because we faced many problems which were beyond our knowledge. Our chemistry teachers also 5 us and made the laboratory available to us. Our first plan was to use fresh fruits 6 the chemicals. We collected pineapple peels (皮) from a fruit market and 7 them as studying materials. After days of experiments we 8 that we were not on the night path because fresh fruits went bad 9 and only had a short-time effect.
We continued studying and continued 10, but the failure gave us the inspiration to improve. In order to achieve better 11 before the annual contest, we worked for many hours, even into the night discussing, trying and improving. 12, we had a good plan to draw the effective substances (物质) from the 13 and make them into a chemical preparation.
Problems were solved and 14 were got over. After five months, we had finally created a machine that could kill many varieties of bad materials in the 15. This invention won the second prize at the annual provincial technology and invention 16 and we applied for a national patent (专利). We were 17 honored because we were the only college students to win a prize.
This memorable 18 taught us not to be afraid of failure which should be used productively to help us discover our 19 points. We did a lot of work but still failed using the original plan. 20, we did not give up. Instead, we discovered factors that led to failure and tried to overcome them. At last, we succeeded.
