What will life be like on Mars? Scientists are planning to send humans to the red planet by 2040. But living there won’t be easy.

First, the journey alone takes about  months. During this time, astronauts will live in a small spacecraft. They must get used to 11_____ in small spaces. There won’t be fresh air or natural sunlight. Instead, they will breathe recycled air and see only 12_____  lights.

When they arrive, they will find a cold and dusty world. The temperature on Mars can drop to -120°C at night. There is also no oxygen to breathe. Astronauts will have to wear heavy spacesuits 13_____  they

go outside. These suits protect them from the cold and radiation.

Building a home on Mars is another big challenge. Scientists plan to use 14_____  from Mars itself. They will dig into the ground to find ice. This ice can be melted into water. Water can then be split into hydrogen and oxygen. The oxygen will be used for 15_____ , and the hydrogen can be used as fuel.

Growing food is also necessary. Mars has poor soil, so scientists are testing special 16_____  that can grow in harsh conditions. They hope to grow potatoes and beans in underground greenhouses. These greenhouses will protect the plants from radiation and keep them warm.

However, living on Mars has 17_____ . Astronauts will be able to see two moons in the sky instead of one. They will watch amazing sunsets where the sky turns blue near the horizon. Despite the difficulties, many people are 18_____  about moving to Mars.

Dr. Chen, a leading scientist, says, “Mars is our next step. It is a chance for humans to start fresh.” But he also warns, “We must respect the environment there. We shouldn’t 19_____  the mistakes we made on Earth.”

Neptune’s New Secret: A Giant Dark Storm

On August 12, 2025, astronomers using the Hubble Space Telescope discovered a new giant dark storm on Neptune. This is the sixth such storm found on the icy giant planet in the past 3___ decades.

Neptune is the eighth planet from the Sun. It is famous for its deep blue color and extremely cold temperatures. The new storm is huge—about 4,800 kilometers wide, nearly the size of the Atlantic Ocean. It appears as a dark spot because it is a hole in the clouds, showing deeper layers of the atmosphere.

Unlike storms on Earth, Neptune’s dark storms spin in the opposite direction. They are high-pressure systems, while Earth’s hurricanes are low-pressure. Scientists believe these storms form deep inside Neptune’s atmosphere, where it is warmer, and then rise to the top. The storm moves at speeds of up to 1,200 kilometers per hour, much faster than any storm on Earth.

Why is this discovery important? First, it helps scientists understand Neptune’s atmosphere. The storm’s movement shows how heat and gases move inside the planet. Second, it gives clues about weather on other gas giants, like Jupiter and Saturn. Third, studying Neptune helps us learn about planets outside our solar system, called exoplanets.

Dr. Sarah, who led the research, said, “Neptune is a mysterious planet. We still know very little about it. This storm tells us that its atmosphere is very active.” She added, “We will keep watching this storm to see how it changes. Storms on Neptune usually last for about 2 years before disappearing.”

The discovery reminds us that our solar system is full of surprises. Even after hundreds of years of studying planets, there is still much to learn. As technology improves, we will uncover more secrets of the universe.

21. What is special about the new storm on Neptune?

A. It is the first storm found on Neptune.

B. It spins in the opposite direction of Earth’s storms.

C. It is caused by human activities.

D. It lasts for more than 10___ years.

22. 特色考法·词汇指代题 What does the underlined word “it” in Paragraph 3 refer to?

A. Neptune.

B. The new storm.

C. The Hubble Space Telescope.

D. The Atlantic Ocean.

23. How long do storms on Neptune usually last?

A. About 1 year.

B. About 2 years.

C. About 3decades.
