　　高分范文示例

　　Scientific advances have an impact on many aspects of our lives, including food. I believe that the increase in food varieties can be beneficial to mankind, although there are some problems.

　　The development of food technology can be beneficial to the health of many people. This is because they are provided with a wider range of high-quality choices to adopt a balanced diet. For example, some perishables such as fruit and vegetables can be preserved and made available for people in cold climates.Some diet supplements have also been developed to improve the nutrition of our diet and promote our well-being.

　　On the other hand, some people argue that the application of advanced food technology can pose health risks, although it can give us more options in our diet. Genetic engineering, for instance, modifies the genetic characteristics of natural crops, but the health consequence of eating these crops is yet to be known. In addition, some chemicals have been used to increase the shelf life of some foodstuffs, despite the fact that these chemicals can harm our health.

　　In my view, the agricultural industry is able to feed a growing population because of technological advances. The main reason for this development is that technology makes a variety of crops resistant to pests and diseases and also enables these crops to grow faster. This can boost food production. These emerging technologies are especially important for developing countries or heavily populated countries, where many people suffer from malnutrition.
