A. Travelling to Mars might become a reality sooner than you think. Scientists are planning to send people (not animals!) to explore Mars in the near future. They believe it’s the only way to find out if there is, or ever has been, life on this planet. They will explore the possibility of living there. So people may go there to live one day!

B. Scientists say that in the future people will live longer. Incurable diseases will be cured and ‘bad’ genes will probably be replaced. With healthier lifestyles and better medical care, the average person will live to be 100 instead of 70 (for men) or 75 (for women) like today. Anti-aging pills will also be invented to help people live longer.

C. Future homes will be located on the ocean, in the air, or underground. These homes will have advanced energy-saving devices such as solar panels, solar windows, and smart home technology. Future homes will take advantage of robots to do chores such as cleaning, cooking, washing, and organizing everything for their owners.
