高1・高2向け｜英語長文問題98（宇宙）143語＋和訳・解答解説

Gravity is the force that pulls us toward Earth, and we feel it every day. It keeps our feet on the ground and makes things fall. During launch, a rocket must fight gravity with great power and lots of fuel. When people travel in space, gravity becomes very weak, so astronauts can float inside their spacecraft. At first it looks fun, but it can also be difficult. Without strong gravity, the body does not work the same way. Muscles and bones can get weaker, so astronauts exercise for about two hours each day. Before a mission, they practice in special pools and in planes that create short moments of weightlessness. Engineers also plan how to land safely, because gravity returns quickly on Earth. After landing, many astronauts feel heavy and tired. With careful training and smart design, space travel becomes safer for everyone.

Choose TWO sentences that are NOT supported by the passage.

1. Gravity keeps people on Earth and makes objects drop down.
2. Rockets need strong engines and plenty of fuel to lift.
3. Astronauts often float in space because gravity is very weak.
4. To stay healthy, astronauts exercise around two hours each day.
5. Astronauts never train on Earth before a space mission begins.
6. After landing, astronauts usually feel light and full of energy.
