A.Science.B.Art.C.History.D.Nature. B Do you know mountains that look like huge stone pillars(石柱)？ Many people feel surprised when they first see the special mountains in Zhangjiajie.How did these mountains form?Let's travel through time to discover their story. Long ago,Zhangjiajie was under water.Rivers brought sand to the seabed.Year after year,new sand fell on the old sand.The heavy new sand pushed the old sand together.After millions of years,the sand became hard rocks.The hard rock was sandstone. Then,something amazing happened.The seabed slowly ascended()and became dry land.The sandstone started breaking into big pieces. Now came nature's artists-wind and water.Strong winds blew against the sandstone,while rainwater made small holes()in the stones.Like a knife cutting cakes,rivers flowed through these holes and made them deeper.These two natural artists slowly changed the sandstone into beautiful stone pillars. But this story isn't over.Even now,wind and rain keep making the stone pillars smaller.Scientists say that after millions more years, these stone pillars will completely disappear.So we're to see this natural wonder before it's all gone!

Looking from the sky,it looks like a huge,bright eye!It is as long as 500 football fields.The Eye looks like a big round pizza with different coloured parts. How was it made?Millions of years ago,the ground under the sand started to rise up.Then,wind and rain slowly wore away the soft rocks,leaving the hard ones behind.Over time,these hard rocks formed the beautiful circles we see today.From above,you can count about 10 round circles,and each one has a different colour.The biggest circle is on the outside,with smaller ones inside. But the Eye of the Sahara is in trouble.The desert is very dry, and sandstorms often blow over it.The sand can make the rocks difficult to see.Also,not many people know about this amazing place because it's far from big cities. What can we do to help?Scientists are studying the Eye to find ways to conserve the rocks from sand.Some people also suggest building a small road or a simple visitor centre nearby.This way,more kids and tourists can come and see the Eye of the Sahara.

Land Diving Most people know bungee jumping.But did you know that bungee jumping started in Vanuatu almost 1,500 years ago?The activity is called land diving here.A man ties two vines()around his feet. He then climbs a wooden tower about 20 to 30 metres high,crosses his arms,and jumps headfirst. Every spring,local boys and men still take part in this traditional activity to show that they are brave.Women can't dive,but they support the divers by dancing and singing.Many tourists come to the island every year to watch this tradition.

Landforms are made by some kinds of force of nature.This force could be wind,water or ice.And it usually takes a very long time to form different landforms.Many landforms are formed by water.For example,you may see many valleys().It used to be a high hill, but as time goes by,water and wind wear down()high land into a plain,and then valleys are formed. What are the differences among the landforms?Valleys are located between hills or with many high mountains around.And there is usually a river at the bottom of the valleys.A delta(三角洲)is another landform created by water.Deltas can be found at the mouths of rivers.They are created when sand,soil and rocks mix together. Hills and mountains are another landforms.A hill is raised land.A mountain is usually higher with a top.Most mountains are like towers but a few of them are like tables.Plains are flat land and plateaus are areas of flat land that are higher than the land around them.

When I was a child,I was shy and scared of speaking in public.My mum encouraged me to get over fear.She always told me,"Don't be afraid,just try."She also spent much time reading with me.When I made mistakes,she never shouted at me.Instead,she helped me to find out the reasons and learn from them.Without her help,I couldn't improve my speaking skills so much. Now I'm confident enough to speak in public and I'm no longer shy. I really want to say thanks to my mum.

To get on well with your mum,first,you should try to talk to her more. Share your thoughts and feelings with her,and also listen to what she has to say.Second,put yourself in her shoes.She cares about you a lot,even if her ways sometimes make you feel uncomfortable.For example,when she asks about your day,it's because she wants to know you better. I hope these suggestions can help you.Everything will be better soon.
