第17题: [多项选择]
独立写作范文 Do you agree or disagree with the following statement: Since the world has changed so much in the past fifty years, advice our grandparents can give us is not useful.
参考答案:SAMPLE ONE   There is a common expression that goes, “with age comes wisdom.” Wisdom is the ability to use your past experience to make good decisions about your future. Regardless of how much the world has changed in the past fifty years, I still believe the advice my grandparents can give me is good.   My grandparents have had a lot of experiences and survived a lot of hardships. When my great grandmother died young, my grandmother had to grow up fast and help raise her brothers and sisters. This was during the Great Depression, when people had to save every penny just to be able to get by. My grandmother has talked with me about how she got through these hard times, and by listening to her stories I have learned many valuable lessons. I have learned to value the things that I have and to work hard for things that I want. When it comes to taking care of my family, I always ask my grandmother for advice.   My grandparents are also a good resource for advice, because they have been around longer and, therefore know more of the world. In my studies, I may have had the opportunities to travel all over the world. While both of my grandfathers have not traveled as much as me, that does not mean they have not experienced the world. During World War II, both of my grandfathers were stationed abroad. They not only lived in Europe for a long period, but they also were able to interact with troops of foreign armies. They did not have the educational opportunities that I have had, but that does not mean that I know more about the world than they do.   Admittedly, there are some areas in which I cannot go to my grandparents for advice, namely technology. Cell phones and computers were not around until my grandparents retired, so they have never had to use this kind of technology for work or study. While my grandparents have tried to keep up with the times, they are certainly not experts. Whenever I visit my grandmother, for example, she always asks me to fix her computer. I would say the only thing I cannot go to my grandparents for advice is anything concerning technology.   Even though there are certain areas in which my grandparents are not that well informed, this does not mean that they do not have good or useful advice. Grandparents’ wisdom from the experiences they have had can give us insight and help us make decisions. SAMPLE TWO   Time witnesses the great progress which we have made in our life. There is no doubt that the modern world has changed a lot over the past several decades. As a result, some people argue that the advices from our grandparents have no use for their grandchildren. Is it true The answer is negative. I maintain that our grandparents’ advices are still constructive in most case.   First of all, no matter how the society has changed, grandparents’ advices especially in the aspect of life and morel are still very helpful. We all might have experience the same cases in our early age. Our grandparents often present us some useful suggestions such as how to get along with other people by sharing their own experience, and we should be honest in any situations. Their advices definitely have severed as good preparation for their grandchild to become excellent adults. Therefore, we should appreciate our grandparents’ helpful advices rather than thinking of their advice is useless.   What’s more, our grandparents accumulate more experience so that they usually have better perspectives in some things. For example, once I encounter the choice of a job with high salary but I am not interested in and a job with a lower salary but I really know lots about it. And meanwhile, my family also suffer big economic burden since my parents lose their jobs. I did not how to choose, in this case, my grandfather suggest me that I should choose job based on my own interest according to his experience, because long-term success depend on performance out of vital interest, interest in certain area could encourage me to take an optimistic viewpoint and continue action to accomplish my goal. Even when facing problems, I might tackle them and move forward. And now, I have achieved some success in my field and it is turn out that my grandfather’s advice is very helpful.   Last but not least, it is commonly acknowledge that our grandparents are out of date. But it is not true. Many old people try hard to catch up with the modern life. They get information from internet and television to enrich their life experienced, they keep themselves update. So I believe that their advices are still very useful.   All in all, I maintain that our grandparents’ advices are still useful whatever the society has changed.
