The Sahara Desert is one of nature’s most extreme temperaments. By day, temperatures soar to 50°C, baking the sand until it burns to the touch. The sun beats down, and the air shimmers with heat—no wind, no shade, just endless gold.

But at night, it flips. Temperatures drop to 10°C, and the desert becomes a different world. Stars blaze brighter than anywhere else, and the sand cools enough to walk on. Animals like desert foxes and owls come out, hunting under the moon.

This swing—scorching days and freezing nights—is the Sahara’s signature temper. It’s harsh, but life here has adapted: cacti store water, lizards burrow to escape the heat, and plants bloom in sudden rains, as if the desert is smiling for a moment.

11. What is the Sahara like during the day?

A. Cold and windy. B. Hot and still.C. Cool and cloudy. D. Wet and green.

12. When do desert foxes come out?

A. During the day. B. At dawn.C. At night. D. After rain.

13. What does “flip” mean in the passage?

A. Change suddenly. B. Stay the same.C. Slow down. D. Get worse.

14. How do plants in the Sahara adapt?

1. They store water in their leaves.
2. They bloom quickly when it rains.
3. They burrow under the sand.

D. They hunt for food at night.

B篇

Tidal waves, or tsunamis, are nature’s sudden, violent temper. They’re usually caused by underwater earthquakes—when the ocean floor shifts, it shoves a huge amount of water upward, creating a wave that races across the sea.

In deep water, tsunamis are hard to spot—they might be only a meter high, moving at 800 km/h. But as they reach shallow coasts, the water piles up, turning into walls of water 10-30 meters high.

In 2004, a tsunami hit the Indian Ocean, killing over 230,000 people. Since then, countries have built early warning systems: buoys in the ocean detect the waves, and sirens sound to warn people to move to high ground.

15. What causes tsunamis?

1. Heavy rain.     B. Underwater earthquakes.

C. Strong winds.  D. Volcanic eruptions.

16. Why are tsunamis hard to spot in deep water?

1. They move too slowly.             B. They’re too small.
