We produce 500 billion of plastic bags in a year worldwide and they are thrown away polluting oceans，killing wildlife and getting dumped in landfills where they take up to 1000 years to decompose. Researchers have been unsuccessfully looking for a solution.
The 16-year-old Canadian high school student， Daniel Burd, from Waterloo Collegiate Institute, has discovered a way to make plastic bags degrade(分解) in as few as 3 months，a finding that won him first prize at the Canada－Wide Science Fair，a $10 000 prize，a $20 000 scholarship, and a chance to revolutionize a major environmental issue.
Burd's strategy was simple: Since plastic does eventually degrade, it must be eaten by microorganisms (微生物). If those microorganisms could be identified, we could put them to work eating the plastic much faster than under normal conditions.
With this goal in mind, he ground plastic bags into a powder and concocted(调制) a solution of household chemicals, yeast(酵母) and tap water to encourage microbes growth. Then he added the plastic powder and let the microbes work their magic for 3 months. Finally，he tested the resulting bacterial culture on plastic bags，exposing one plastic sample to dead bacteria as a control. Sure enough, the plastic exposed (暴露) to the live bacteria was 17% lighter than the control after six weeks.
The inputs are cheap：maintaining the required temperature takes little energy because microbes produce heat as they work, and the only outputs are water and tiny levels of carbon dioxide.
“Almost every week I have to do chores and when I open the closet door, I have piles of plastic bags falling on top of me. One day, I got tired of it and I wanted to know what other people are doing with these plastic bags. The answer：not much. So I decided to do something myself.” said Daniel Burd.
1. Daniel Burd won first prize at the Canada－Wide Science Fair because________.
A. he found a new kind of microorganism
B. he contributed much to environmental protection
C. he found a way to degrade plastics in shorter time
D. he could encourage microbes growth in an easier way
2. Daniel Burd exposed one plastic sample to dead bacteria to
________.
A. make the live bacteria work better
B. test how effective his method was
C. know which bacteria worked faster
D. control the temperature in the process
3. Maintaining the required temperature takes little energy because ________.
A. plastics can get hot easily
B. microbes can produce heat themselves
C. much carbon dioxide is produced
D. the temperature can be controlled
4. Daniel Burd got his idea from ________.
A. his school textbook
B. the failure of researchers
C. his everyday work
D. the practice of other people

What do you learn from this lesson?[Homework] Review the language points of this class.本堂课基本完成了教学任务，时间分配较为合理，达到了教学目标，但也存在一些问题，需要我在今后的教学过程中加以调整和完善。
本堂课在多媒体等教学工具的辅助下，营造了较良好的参与环境和宽松、和谐、融洽的学习氛围；由于本班中等生占大多数，因此本堂课以中层水平的学生为主要教学对象，同时兼顾其他层次学生，任务型教学活动以中等难度进行设置，形式活泼多样，激发了学生学习的积极性和主动性，为学生创造了良好的参与条件，提供了合适的参与机会，组织学生独立思考与集体讨论，保证了学生积极有效的参与；在讨论中，同学们畅所欲言，不仅活跃了课堂气氛，同时也锻炼了同学们的思维，为语言应用奠定了基础；最后的分组成文和学生点评也进展的较为顺利，基本达到了预期的教学效果。
但是由于学生英语听说能力相对较弱，授课采用较深的全英教学，同学们还不能适应，从而影响了教学效果。同时部分学生学习比较死板，良好的上课效果还需要充分调动学生的积极性，因此又需要驾驭课堂的能力，而我在这方面还有所欠缺。
在今后的教学中，我会总结经验，吸取教训，多向其他教师学习，不断提高自己的教学水平，呈现出更好的课堂。
