Firstly, exploring space has already made a difference in the fight against world hunger . It has directly resulted in the many satellites that now orbit Earth. A number of the satellites record data on land and weather patterns. Then the data is transmitted to scientists on Earth. After careful analysis, the scientists can provide useful recommendations and advice for farmers. As a result, Space-based science has helped farming in its efforts to grow enough food to feed Earth’s increasing population.

For example, space technologies have helped the research and development of different types of new material. They have also helped
companies make better heart monitors and other machines that doctors regularly use. Today ,space technologies are widely used in all kinds of industries, and everyday products such as GPS, memory foam pillows, and smartphone cameras are changing our lives.

Evidence 3
Finally, sending astronauts into space has helped people to think about the world’s problems and even to find ways to solve them. Seeing pictures of our planet as an Island in a black sea made people realise that out planet’s resources are limited. In order to provide for such a rapidly increasing population, scientists are trying to find other planets that could one day be our new home. The greatest attention at present is on Mars because it is closer to Earth. In the future, humans may live on both planets.

第二步：明确论点
第三步：建构文章
Recently our class had a heated discussion on whether space is worth exploring. Students hold different ideas about it.
30% of us think space exploration is not worthwhile, holding the belief that space exploration is too far away from us and our daily life and is a waste of money.
However, 70% think space is worth exploring because we have benefited a lot from it, such as using satellites for communication and weather forecast. What’s more, with further space research, we may solve the population problem by moving to other planets one day.
As far as I am concerned, it is worthwhile to explore the space. Not only can it promote the development of society but also enrich our life.
