内容正文:
During our traditional festivals,family and
friends get together to celebrate.We share spe-
cial food.It's important to avoid saying unlucky
things.
These are some key cultural customs.I hope
you'll enjoy your stay in China!
One possible version:
Last weekend,I volunteered at a community
centre for left-behind children.
I helped teach them English,read interesting
stories aloud,and played fun games with them.
参
Seeing their bright smiles made me really happy
I also helped clean the reading room and pre-
pared small gifts for them.
案
This experience taught me that even small
acts of kindness can warm others'hearts.Volun-
teering helps me grow and makes me understand
the meaning of giving.I will keep on volunteering
and use my youth to spread love and warmth.

One possible version:
Dear Tina,
Last summer,I had an accident during a hi-
king trip with my friends.When climbing a hill,I
fell and hurt my leg badly.
My friend Lucy quickly helped me.First,she
made me sit down and kept my leg still.Then she
used a clean cloth to stop the bleeding.After
that,she called for help.Thanks to her first aid,I
felt much better before the doctor arrived.This
experience taught me that knowing first aid is
very important.I hope everyone can learn some
first aid skills

dark.As usual,my mother picked me up after
school.On our way home,however,the wind
blew more and more strongly.Lots of litter was
blown up in the sky and the big trees began to
shake with the leaves falling down.We felt there
was something unusual.So we walked fast.Un-
luckily,the wind was so strong that we couldn't
hold the umbrella.The heavy rain kept falling
down.We got wet and the cold went through our
bodies.Soon,we began to realize that maybe a
typhoon was hitting the area.We became scared
and began to run.But it was hard for us to run
fast as the wind kept blowing strongly.After a
few minutes,we arrived home but all the clothes
were wet.Later,when we watched the news on-
line,we learned that there was really a terrible
typhoon in our area and it caused lots of dam-
age.We were lucky as all of us were fine after
all.

The world's smallest island is called Just
Room Enough Island.It lies between the US and
Canada and is just about 310 square metres.It is
an island with just enough room for its owner's
house,a couple of trees and a small beach with a
pair of chairs.Just Room Enough Island was
bought by the Sizeland family.The family wanted
to build it as a comfortable vacation home.They
used boats to bring building materials from the
bank.And then they built the house,planted trees
and grass on the island.The family never expec-
ted to be visited by tourists.In order to be called
an island,their land must have an area larger
than one square foot,stay above water all year
and have at least one tree.The last one didn't
come true,so they had to plant trees.

organization to help the poor in their community.
The students started their day early.They met at the school gate and
then took a bus to the charity centre.When they arrived,they were divided

make a big difference in their lives,"said Lucy,another student.

The Yellow River is the national treasure of China.People along its
banks always worry about floods.36 Now,scientists can solve these
problems better using a digital()copy of the river,helping in flood
control.
The digital copy uses technologies like big data,AI,and the Internet of
Things.Tools set along the river collect data and send it to a control cen-
tre.37 As a result.a 3D view on screens shows the river's live condi
tion,acting as its digital twin.
A great success here is "smart stones".They are tools shaped like re-
al stones.38 These sensors(传感器)help avoid serious dangers in
flood prevention work.
In the control centre,researchers get big help from such tools.Be-
fore,workers had to visit the dike()to gather data,risking their lives
and using lots of time.But now,these devices do the job.39
Above the water,drones(无人机)fly in the air.40 They take
photos and share reports so that experts can update the 3D model any
time.Together with tools below water,this tech protects the whole Yellow
River Basin in every way,making future digital management more amaz-
