Improved sample
I like my high school math teacher for three reasons. First, he teaches very well and his class is more interesting compared with other classes. He takes every opportunity to show how interesting math is; for example, he often plays number games in class, which is an important source of our enjoyment. Another reason is that he is very enthusiastic about his work. He always tells us how important math is, and he tells stories about great mathematicians, which encourage us to work hard. Next, my math teacher has a good sense of humor. Math class can be rather dull with formulas and numbers, but the teacher’s humorous remarks and jokes refresh and amuse us so that we never feel bored and are always able to pay attention to the subject.
2. Limit your essay to a discussion of recent, major causes or effects. • A car wreck • major reasons: defective brakes, a hidden yield sign, bad weather.
3. Cause-and-Effect Chain • Cause 1st effect cause 2nd Effect cause 3rd Effect (bad weather) (car wreck) (wet brakes) (doctor bills)
Example: • John got his left leg injured in a car accident (the original cause). Then he had to be hospitalized for three months.(the first effect). • Due to his stay in the hospital ( the second cause), he missed his lessons for three months ( the second effect). • Because of his absence from school (the third cause), he failed to attend the courses of the term( the third effect). • Owing to his failure to attend the courses of the term( the fourth cause), he failed in the final examination of the term (the fourth effect).
Use part of a point as evidence to support the point---also known as begging the question(回避 问题实质)
E.g: Mr. green is a great teacher because he is so wonderful at teaching. • Point: Mr. Green is a great teacher. • Support: he is so wonderful at teaching The point and the support is really the same.
• 1. Cause You are out of gas. Effect Your car won't start. 2. Cause the bad weather Effect: the car accident Cause asks : why did/does/ will X happen? Effect asks: What did/does/will Y produce?
