The world’s largest reef (礁), the Great Barrier Reef, has lost more than half of its coral (珊瑚) cover in the past 30 years because of global (全球) warming. The beauty of the Australian coast has been left lifeless.
Scientists have been trying to find ways to save it, and now they may have found a special helping hand---volcanoes(火山).
During a volcano eruption(火山喷发)，wherever hot lava(岩浆) goes, villages and plants are burned right down to the ground. How could it possible save life on Earth?
When the lava goes into the ocean, it quickly cools down and becomes light rocks that can float in the water. For example, in 2006, shortly after the eruption of a volcano near Tanga, a southwest Pacific island, scientists found many large rocks floating on the ocean. These rocks traveled a long way from the island to Australia over the next eight months.
But they didn’t just float during this time—they acted like little lifeboat. Scientists found that the rocks “picked up” more than 80 kinds of corals, crabs and other life animals on their way, before arriving at the Great Barrier Reef.
Once near the reef, these animal “passengers” can easily jump onto the rocks and go to their new home. “It’s like a boat of people landing on an island,” Judith Winston, a biologist at the Virginia Museum of Natural History, US, told Scientific American.
Since volcanoes have been on Earth for all of history, scientists say these “Lifeboats” might have even helped form the Great Barrier Reef in the first place.
1.What problem does the Great Barrier Reef face?
A. There is less and less coral cover because of global warming.
B. It lies in an area with volcanoes happening now and then.
C. There are no living things on the Great Barrier Reef
D. The Great Barrier Reef is getting smaller and smaller.
2.Which is the right order of the following event, according to the passage?
(1) Lots of little animals climb onto the rocks.
(2) Many huge light rocks are floating on the ocean.
(3) Lava goes into the ocean after the eruption of a volcano.
(4) Animals move to their new home through the rocks.
A. (4) -- (3) -- (1)-- (2) B. (2)-- (1)-- (4)-- (3)
C. (3 )-- (1)-- (2)-- (4) D. (3)-- (2)-- (1)-- (4)
3.What’s the main idea of the passage?
A. The beauty of the Great Barrier Reef is going away.
B. Volcanoes can help the Great Barrier Reef become lively again.
C. Global warming has a bad influence on the Great Barrier Reef.
D. Save volcanoes, save the Great Barrier Reef

九年级英语阅读理解困难题查看答案及解析
China is a great country with the largest population in the world．In order to solve the population problem，our government decides to have one-child policy．When it is carried out for some time，many people see not only its advantages but also its disadvantages．Therefore，one-child policy has been out of date，and two-child policy has been carried out these days．
If you have a brother or sister, you already know you are different from each other．You live together in the same house and with the same parents，but you have different personalities．
Why is this? One possible reason is the way your parents treat you·
First-born children receive all the attention from their parents．Most families have twice as many photos of a first-born as any other child．Parents usually give first-bores more responsibility(责任)and depend on them to take care of younger brothers and sisters．As a result，first-borns are often responsible，hard-working and serious．They often want to do well at school and work．There are more first-born American presidents…such as George W Bush，George Washington，and Lyndon Baines Johnson---than the second or last-born children．
When a second child arrives，parents usually feel less excited．The second child has to compete with the first-born for the parents’ attention and love．These children often choose different sports and hobbies to do well at school and work，but have to be creative to get their family’s attention．They are often friendly and cool．Many famous talk-show hosts were born last．
根据短文内容，完成下列各题。
1.Has two-child policy been carried out in China these days?
2.Which ones are more possible to be presidents，first-borns or second-borns?
3.How do parents usually feel when a second child arrives?
