Spring and Autumn Holidays for Students
The 2026 Government Work Report says China will help some areas to have spring and autumn
holidays for primary and secondary school students.And workers can take their holidays at different
times.This policy (has been tried in Zhejiang,Jiangsu and Sichuan.
These holidays are good for students.They can help students reduce study pressure after long-
time learning,and keep them healthy both in body and mind.With nice weather,students can go
out of the classroom to do many interesting activities,like farming,watching nature and learning
local culture.In this way,they can turn book knowledge into real-life experience.
The holidays are also good for families.Parents can spend happy time with their children at low
cost,without the crowds of busy travel seasons.Many families travel,visit relatives or go to museums
together,making family relationships closer.The holidays also help local tourism and economy.
However,there are some problems.The main one is that many working parents can't look
after their children during holidays.To solve this,schools offer after-school care with fun activities,
and communities also have more programs for students.Holidays can be set differently according to
local situations.
In short,spring and autumn holidays are a great change for education.They help students
grow in a healthier and more meaningful way with the help of families,schools and society.
24.What can the holidays do for students?
A.Increase their study pressure.
B.Keep them healthy only in body.
C.Help them turn book knowledge into real-life experience.
25.Why are the holidays good for families?
A.Parents can spend time with kids at low cost.
B.Parents have to pay more for travel.
C.Families can only visit museums.
26.What is the main problem of the policy?
A.Students have no activities to join.
B.Schools refuse to offer after-school care.
C.Many working parents can't look after their kids.
27.What can we learn from the last paragraph?

①Do you like blueberries(蓝莓)?Have you ever wondered why these tiny berries appear
such a bright blue color while their flesh is clearly white?If so,the next time you're about to enjoy
these delicious berries,take a good look at them.Then ask yourself:Are blueberries really blue?
2For the most part,blueberries aren't blue.If you carefully peel (the skin off one,
you'll see that the flesh inside is white.If you rub the inside of the skin on a white piece of paper,
you'll see a reddish-purple color.And if you gently rub the outside of a blueberry,the blue color
disappears and the berry looks almost black.But the moment you pick one,it does look blue.
What's going on?
3Well,there are two ways to create colors.The first is through pigments,which are things
that can show the color of the light they don't take in.The most usual thing in plants is chlorophyll
(叶绿素),a green pigment..Plant leaves appear green because chlorophyll doesn't take in green
light.Instead,it sends it out while taking in blue and red light.Plants prefer to take in blue light
because it has more energy than any other light.In fact,there aren't any "true blue"pigments in
the plant world.
4The second way to make color is through "structural color.This happens when the structure
of a surface makes some colors of light look different.Have you ever seen the rainbow colors on a
CD?These colors show up because of the tiny spaces between the disk's thin layers.These spaces
only allow certain colors to reach our eyes.
5Now your bowl of blueberries suddenly looks a lot more interesting.The fruit is beautiful,
but its beauty is only skin deep!
32.How does the writer begin the passage?
A.By listing numbers.
B.By asking questions.C.By explaining reasons
33.What does the word "pigments"mean in Paragraph 3?
A.Things that give colors to plants.
B.Energy that helps plants grow.
C.Light that plants take in.
34.What does the passage mainly talk about?
A.Why blueberries appear blue.
B.How blueberries got their name.
C.Why blueberries taste delicious.
35.Which is the best structure of the passage?
A.①+②→③→④-→⑤B.①②→③④-+⑤
C.①→②→③④→⑤

Travelers today can fly across continents (within hours.However,centuries ago,
journeys across different continents were much more difficult because of poor transportation.One of
the most famous paths of ancient times was the Silk Road.It wasn't actually a single road,but a
huge network of connected paths.This network 47 across Asia,linking the East and the
West.
It all began with the Chinese and their secret skills of silk production.To the western world,
silk was a wonderful material.Nothing else was as 48 or had such a beautiful shine.Because
they wanted to get this special cloth,businessmen and traders from faraway lands started on
dangerous trips.
In fact,the Silk Road wasn't only about silk.When traders travelled,they brought with them
many different 49 things like spices from India and paper from China.Goods were not the only
things moving along these paths.The road became a way to exchange 50,too.Technologies,

people to keep going.

In eastern China's Shandong Province,there is a mountain called Mount Tai.It has long been
famous for its beautiful views.The mountain is a UNESCO World Heritage Site and has millions of
visitors every year.
But all of those visitors face the same problem-the 7,000 steps they have to take to get to the
top of the 1,500-meter-high mountain!
To help with this,.robotic exoskeletons(机器人外骨骼)were tested on the mountain earlier

About 200 people paid $8 to 11 to use them.The exoskeletons are worn on the waist and
legs and weigh only 1.8 kilograms.They use AI to sense movements and give extra power to the
legs,so people don't get too tired.
The experiment was done by Taishan Cultural Tourism Group (TCTG)and Kenqing Technology,
the company that made the exoskeletons.Wang Houzhe from TCTG said that the exoskeletons were
introduced to help older people enjoy climbing the mountain,instead of just taking a cable car(

It's reported that half the people who used the exoskeletons during the test at Mount Tai were
old people.
Besides helping older people and regular hikers,Kenqing Technology believes that its product
could be used to help rescue services,industrial workers,and disabled people.

Tai told Xinhua News Agency.
