In our busy lives，we often sacrifice(牺牲)sleep to study，work，or have fun. However，sleep is not a waste of time. It is as essential to our health as eating healthy food and exercising regularly. For students，getting enough quality sleep is one of the smartest things you can do for your body and mind.
When you sleep，your body is busy repairing itself. It strengthens your immune system(免疫系统)，which helps you fight off illnesses like colds and flu. Meanwhile，your brain is also hard at work. It processes the information you learned during the day，moving it from short - term memory to long - term memory. This means that a good night’s sleep can actually help you remember facts for a test better than studying for hours without rest. Lack of sleep，on the other hand，makes it difficult to concentrate in class. You may feel irritable(易怒的)，find it hard to make decisions，or even feel sad.
So，how can you improve your sleep? First，try to go to bed and wake up at the same time every day，even on weekends. This helps your body’s internal clock. Second，create a relaxing bedtime routine，such as reading a book or taking a warm bath. Finally，avoid screens from phones or computers for at least an hour before bed，because the blue light can trick your brain into thinking it is still daytime.
Making sleep a priority(优先的事)will not only make you feel better but also help you perform better in every aspect of your life.

C
Humans have always been curious about the unknown. We have climbed the highest mountains，dived into the deepest oceans，and even traveled to space. But why do we take these risks?
One reason is curiosity. We want to know what is at the top of Mount Qomolangma or what lives at the bottom of the Mariana Trench. This desire to learn and discover pushes us forward. Another reason is the challenge. For many explorers，the difficulty is the point. Overcoming huge challenges gives them a great sense of achievement. They want to test the limits of human ability.
However，exploration is not just for personal satisfaction. It often leads to important scientific discoveries. For example，researching the deep sea helps us understand climate change and discover new species(物种). Exploring space helps us learn about the origin of the universe.
Of course，exploration is risky. Climbers can fall，and divers can face dangerous animals. But for explorers，the rewards are greater than the risks. As George Mallory said about climbing Qomolangma，“Because it’s there.” This simple statement captures(捕捉)the spirit of exploration：the desire to see what is beyond the next hill，just for the sake of seeing it.
57. Which of the following is NOT mentioned as a reason for exploration?
A. Scientific research.
B. Personal curiosity.
C. Getting famous.
D. Facing challenges.
58. What does George Mallory’s statement “Because it’s there.” show about explorers?
A. They don’t need a clear reason to explore.
B. They are very careless.
C. They only care about mountains.
D. They want to become rich.
59. What can we infer from the passage?
A. Exploration is always safe and easy.
B. Exploration only benefits the explorers themselves.
C. The spirit of exploration is part of human nature.
D. There is nothing left to explore on Earth.
60. What is the best title for the passage?
A. The Dangers of Exploration
B. Famous Explorers in History
C. The Reasons and Value of Exploration
D. Scientific Discoveries from Exploration
