The Dead Sea, located between Israel and Jordan, is not a real sea but a salt lake. It is one of the most unique natural wonders on Earth. With a salt content much higher than that of ordinary seas, it allows people to float easily on its surface—you can even read a book while floating!
The Dead Sea is about 430 metres below sea level, making it the lowest point on Earth’s land surface. Rivers flow into it, but there is no outlet for water to flow out. Over time, the water evaporates, leaving behind large amounts of salt and minerals. This is why the lake is so salty.
However, the Dead Sea is facing a serious problem. Due to human activities, people take too much water from the rivers that feed it. As a result, the water level of the Dead Sea is dropping year by year, and its area is getting smaller. If this continues, the Dead Sea may dry up within the next 100 years.
Despite its name, the Dead Sea is not completely lifeless. Some special bacteria and algae can survive in its extremely salty water. The surrounding area is also home to unique plants and animals that have adapted to the harsh environment.
（ ）Why can people float easily on the Dead Sea
A. Because it is very deep. B. Because its water is very clear.
C. Because its salt content is very high. D. Because it is a large lake.
（ ）What is the Dead Sea’s position on Earth
A. It is the highest lake on Earth. B. It is the lowest point on Earth’s land surface.
C. It is the largest salt lake on Earth. D. It is the deepest lake on Earth.
（ ）What problem is the Dead Sea facing
A. Its salt content is decreasing. B. Its water level is rising.
C. Its area is getting smaller. D. It is being polluted by humans.
（ ）Which of the following can survive in the Dead Sea
A. Fish and shrimp. B. Bacteria and algae.
C. Dolphins and whales. D. Trees and flowers.
（ ）What is the main idea of this passage
A. To explain why the Dead Sea is so salty.
B. To introduce the Dead Sea and its current situation.
C. To describe the plants and animals in the Dead Sea.
D. To suggest ways to protect the Dead Sea.
