Background Viewpoint 1 Read for structure and writing techniques Countries around the globe are spending billions of dollars and lots of time on various space missions, whether to Mars or other planets much further away.

However, others feel this is a shallow view which fails to realize how exploring space helps us. Read para.1 to underline the background and different viewpoints. What argumentative technique （论证方法）does the author use to make his viewpoint more clearly? Comparison 对比 Read for structure and writing techniques 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. Read para.2 to find the topic sentence and evidence.

Secondly, space exploration has already promoted technological improvements that benefit us all. High-end products around the world are made to a higher standard now because of advanced technology which was first created to meet the requirements for space exploration. For example, space technologies have helped the research and development of different types of new materials. 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.

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 realize that our 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.

Are there any grammar, spelling, or punctuation errors? Examples Space Exploration: A Worthwhile Investment I strongly believe that space exploration is important for humanity. Although it is expensive, the benefits far outweigh the costs. First of all, space technology improves daily life. For example, GPS and weather satellites rely on space research. Second, exploring space inspires young people to study science. Many students choose STEM careers because of space missions. Finally, finding new resources in space could solve Earth's energy problems. Scientists say asteroids contain valuable metals. In conclusion, space exploration brings practical benefits, encourages education, and may provide future resources. We should continue supporting it. Examples Space Exploration: A Waste of Resources? I believe space exploration is not worth the cost. While it seems exciting, the money and effort should be spent solving Earth's problems instead. First, space missions are extremely expensive. NASA’s 2022 budget was $24 billion—enough to build thousands of schools or hospitals. Second, space travel is dangerous. Astronauts face risks like radiation and equipment failure, as seen in past accidents. Third, we haven’t even fully explored our oceans, which are more directly useful for food and medicine. In a word, space exploration drains resources we urgently need on Earth. Governments should focus on poverty, healthcare, and climate change first. Homework Finish your essay about space exploration.
