In the future, we will find ourselves depending more and more on fresh water from the sea.
The sea gives us food, fertilizer, minerals, water and other gifts. What do we give the sea? We pollute the ocean all the time. 5. Throwing waste into the ocean is killing off sea life. Yet as the world population grows, we may need the sea and its gifts more than ever.
We are finally learning that if we destroy our sea, we might also destroy ourselves. Hopefully, it is not too late.

The temperature on the surface of Mars is -73℃—20℃. 20℃ is suitable for humans, and -73℃ is near the average temperature of the Antarctic (南极), 3. And we have made a real trip to Mars. It would take 6 months to fly to Mars by spaceship. However, 4. Of course, humans can live through this by living in buildings, where plants could be grown and used to produce oxygen.
Scientists said that Kepler-452b is an Earth-like planet. Because it is only about 1.5 times the diameter of Earth, circling a star very much like our own Sun Although we don’t know if we can live there, it lies on the right distance where water could exist (存在). 5. But it is too far from us. Using present technology, it would take 25.8 million years to get there. So far, we’ve no hope of getting there.
A. so temperature isn’t a problem on Mars.
B. But until recently, a planet- Kepler452 b has been found by NASA (美国家航空航天局).

How much do you know about Earth-the planet that we live on? Our knowledge of Earth has been developing since ancient times. However, many puzzles about Earth remain unsolved. Live Science has published a list of the eight biggest mysteries about Earth. Let's look at some of them.
Where did water come from?
When it first came into being 4.5 billion years ago, Earth was a dry rock. So where did all of our water come from? Scientists think that it might have arrived in the form of ice by an asteroid(小行星) from outer space that hit our planet. But this theory has not been confirmed because there is very little related evidence(相关证据)to be studied.
What's in the core(地核)?
Scientists used to study meteorites(陨石)as small examples of Earth, believing that Earth's core was made of iron and nickel(镍). However, a later study in the 1950s proved this way to be wrong because it found that Earth would be too light to provide gravity if its core contained only iron and nickel. Today, scientists continue to bring forward different theories, but none have been confirmed.
How was the Moon born?
Scientists have found that the chemical compositions(成分)of Earth and the Moon are very similar. That suggests that the Moon actually came from Earth. For example, it could be a piece of Earth that separated when Earth hit another planet. It is also possible that when Earth first came into being, it spun(旋转)very fast and threw off enough molten(熔化的)rock to later from the Moon.
1.What's the story mainly about?
A.How Earth came into being. B.Where Earth's water came from.
C.How the Moon was formed. D.Unexplained mysteries about Earth.
2.What do we know about where water may come from?
A.Earth's water may come from ice that melted 4.5 billion years ago.
B.Earth's water may come from a small planet that hit Earth.
C.We don't know where water came from.
D.There is lots of evidence that tells us where water came from.
3.What does the underlined phrase "bring forward" in Paragraph 5 probably mean?
A.Check. B.Raise. C.Improve. D.Receive.
4.Which of the following is TURE according to the passage?
A.Scientists believed Earth's core was made of meteorites.
B.A study in the 1950s proved that Earth's core is made of iron and nickel.
C.The Moon and Earth are made of similar materials.
D.Three possibilities of where the Moon came from are mentioned.

Tiny plants and animals live all around us.We cannot see them because they are so small,but they are everywhere. They live in the soil,in the air,and in rivers and oceans.They grow on mountains and in caves.Some live in the ice at the north and south poles; some live where it is very hot.They are found throughout cities and in the country. They grow on other plants and animals.Some are even living on you,on your skin,hair,and inside your body,in your mouth,nose,and all through your body.
These tiny plants and animals are called microbes.The word microbe is made from two other words:micro,meaning small,and bios,meaning life.So,microbe means small life.
Microbes have been on earth for a very long time.They may have been the first forms of life to be alive.Today there are more microbes in the world than all other living things.
People did not know microbes had existed(存在) long.They were too small for them to see.But people did see many changes in their world﹣important changes.And they did not know what caused them.They saw food that they kept too long change color and begin to smell bad.They saw cuts and wounds grow red and painful and become worse. They saw old plants and leaves and trees crumble apart on the forest floor and disappear into the soil.Such changes were a natural part of the world,but people did not understand them.They did not know these changes were evidence(证据) of tiny plants and animals growing all around them.
1.Why couldn't people see microbes?
A. Because they are too small.
B. Because they live inside our body.
C. Because they live far from humans.
D. Because they may have been the first forms of life to be alive.
2.The underlined phrase" crumble apart" in the last paragraph means" ".
A. grow taller B. change into soil
C. break into tiny pieces D. become colorful and energetic
3.Choose the answer that completes the web below.
A. Microbes are very small B. Microbes are all around us
C. People can't see microbes D. Food begins to smell bad
