二、阅读理解
Islands are always changing their shapes, and sometimes, you may see the change happening. As a volcano(火山) near the island erupts(爆发), it spew out(喷出)streams of red-hot lava(熔岩). When the lava reaches the water around the island, it cools and forms new rocks, and the island grows.
Most changes are hard to see. Storms and winds usually carry dirt and sand from one side of the island to the other side. Sea waves wash away soil and rocks from one beach and take them to another. So, the island changes the shape slowly, a tiny bit at a time.
However, people on some small islands are worried, because they think their islands are changing shapes too fast. They see waves rise higher and further onto shores than they used to, and storms and winds are growing stronger too. What's worse, some places have been flooded. For example, in the Solomon Islands, a country made up of small islands in the Pacific Ocean, five islands have disappeared.
Scientists believe that it is because of global warming. With more gas and coal burnt for cars and factories, people produce more greenhouse gas and make the Earth warmer. Then, more ice melts and more water flows into the ocean, and sea level rises.
But there is hope. Scientists are looking for ways to stop sea level rising and clean ways to run cars and factories. We can also help by recycling, planting trees, driving less, and wasting less. By doing these things, we can save more islands from disappearing.
11. How does an island grow
A. The red-hot lava cools and forms new rocks.
B. The volcano gets bigger and makes it grow.
C. The sea waves bring soil and rocks to it.
D. The sea level becomes lower.
12. What are the causes of the disappearence of islands
①More volcano eruptions.
②Warmer climate.
③Higher sea level.
④More gas and coal being burned.
A. ①② B. ③④ C. ①②③ D. ②③④
13. Which way can prevent the islands from disappearing
A. Making more land by lava.
B. Running factories with green energy.
C. Moving people on islands to other places.
D. Burning more gas and coal.
14. What can we infer(推断) from the passage
A. The islands will get smaller and disappear someday.
B. Keeping islands from disappearing is possible.
C. Islands always change shapes, but now such changes are slow.
D. Solomon Islands have disappeared from the world.
15. What's the scientists' attitude (态度) about disappearing islands according to the last paragraph
A. Hopeful. B. Negative. C. Doubtful. D. Careful.
