Zhang Guimei，the principal of Huaping High School for Girls，has been given the title "Role Model of the Times" for helping girls from poor families.
The school was the first high school in the country to provide free education for girls who would otherwise have been unable to continue their studies after completing their nine years of education.
Zhang moved to Lijiang at the age of 17 to teach in the middle school in Huaping County.Once，she got badly ill but had no money for the treatment（治疗）.With the help of the people there，she was able to get the necessary treatment. "From then on，I told myself that I must do something for those people who helped me，" Zhang said.
Slowly，a dream of setting up a free high school for girls in Huaping County appeared in Zhang's heart.From the year of 2002，she began a six﹣year journey to look for funds（资金）.In 2008，Zhang finally set up Huaping High School for Girls at the foot of the Shizi Mountain in Huaping.
Thanks to her efforts，more than 1，800 girls from poor families have entered universities through her education until now.
Zhang has been helping to improve the area as a whole.Influenced by her，many of her students have chosen to teach in poor areas .Now，with Zhang having got the honorary title，education for girls from poor areas will receive more attention.
What she has done will be long remembered and encourage more to follow her example.
（1）Why was Zhang Guimei named "Role Model of the Times"？
（2）Was Zhang able to get the necessary treatment when she once got badly ill？
（3）When was Huaping High School for Girls set up？

Huge Waves Destroying Arctic Ice Faster than Expected
Ice covers much of the Arctic Ocean.Some pieces of ice are huge，like moving islands.As temperatures have increased ，however，some of the ice has begun to disappear.Scientists have discovered huge waves in the arctic waters.
The waves were discovered by accident in May，2010.Scientist Aleksey Marchenko and his students set out on a trip.They wanted to study the icy waters.
The ship travelled east and stopped next to a large block of ice around 50 miles from the small island of Hopen.Marchenko prepared to lead his students out onto the ice.
"We were ready to go but when I went out，I discovered many cracks around，" he remembers.
He decided to move the ship deeper into the ice to keep safe.The farther in they went，he thought，the harder the ice would become.As they pushed forward，however，the ship experienced small waves，and then bigger ones.Soon，the waves broke up the ice around the ship into thousands of smaller pieces.
Within an hour，Marchenko and his team saw a wave that was about 13 feet high.The ship's navigation system finally recorded the largest waves.They were more than 20 feet in height.The waves were so strong that they forced huge pieces of ice to jump up and down，breaking the ice into smaller pieces within just one hour.Scientists had never imagined that the process could happen so fast.The waves in these areas used to be small.
The speed and force of the huge waves there makes it impossible to know in advance when they are coming.That could be dangerous for navigators and local communities who are unprepared for huge waved or depend on sea ice to protect them.Wildlife like polar bears that depend on sea ice to live is also in danger.
Some scientists think people will soon see even bigger waves in icy waters.As waves break up ice ，seas will be more open，waves will be stronger.There are stormy times ahead.
根据短文内容，请用完整句子回答下列问题。
（1）When did Marchenko and his students discover huge waves in the arctic waters？
（2）What happened to the ice around the ship when the ship moved into the ice？
（3）How high were the largest waves recorded by the navigation system？
（4）What animals will be in danger because of the huge waves？

Poverty （贫困）is a big problem around the world.But China has done a good job of dealing with it and it has found its own way to fight poverty.Instead of just giving money to poor people，it has tried to educate people and give them the tools they need to lift themselves out of poverty.Ordinary （平凡的）people play a big role in the fight.Here are two of them.
After graduating from Beijing Normal University in 2016，Huang Wenxiu gave up the chances to work in big cities and returned to her hometown of Baise in Guangxi and served as the village's Party chief.A total of 418 villagers were lifted out of poverty thanks to her efforts.Unluckily，she died in a flash flood at the age of 30 while driving back to her village in Baise.She was given the title "role model of the times" by the central government.
When Mao Xianglin started to work as the Party secretary of his village，there was only one pathway out of the village for many years.He led more than 100 villagers to build a road with their hands. It took them seven years to build an eight ﹣ kilometer road. Mao then encouraged the villagers to grow oranges.Last year，their orange yield （产量）was nearly 40 tons.Young people have returned to the village to sell oranges online.By the end of 2019，269 villagers had been lifted out of poverty.The per capita income （人均收入）reached 12，670 yuan，40 times more than in the 1990s.
（1）How does China help poor people to fight poverty？
（2）What prize was given to Huang Wenxiu？
（3）How do young people sell oranges in Mao Xianglin s village？
（4）请把文中的划线句子翻译成汉语。
（5）请给短文拟一个恰当的标题。
What time does your school start？Do you wish you could get up later every morning？You are not alone if your answer is "Yes." In the US，many middle school students have the same wish.
In America，many schools start before 7：30 am.But that may change soon.A new law has been passed in California.According to the law，middle schools should not start before 8：00 am.The government hopes school children will have longer time in bed.
Many scientific studies show that teenagers are more active in the afternoon and in the evening.Simply telling them to go to bed earlier doesn't work well.Most of them don't get enough sleep because of bad sleeping habits and early school starting time.They need more sleep in the morning.Scientists suggest middle schools should start at 8：00 am.or later.Students can get well ready to learn and they won't fall asleep in class.______The change can help improve students' grades.
While scientists are happy with the new law，many parents disagree with it.They won't be able to send their children to school before they go to work.They also fear that later school starting time will lead to later ending time.As a result，their children will have less time to take part in after﹣school activities.

Have you ever imagined the life in space？The following will show you the astronauts' daily life.
• Eating in space
If you go camping for more than a week with some friends，you will make sure you have plenty of foods and keep them properly.At the end of your camping trip，you would deal with your rubbish properly before the ride home.
Astronauts almost do the same thing when they go to space.Preparation changes with the food type.Some foods can be eaten in their natural forms，such as chocolate cakes and fruits.Other foods require adding water，such as cheese.Of course，an oven is provided at the space station to heat the food.But there are no fridges，so space food must be kept properly.
• Sleeping in space
After a long day at work，nothing is better than a good night's sleep!Just like on the earth，in space astronauts go to bed at a certain time，then get up and prepare for work again.When going to sleep，they have to attachthemselves，so they don't float （漂浮） around or hit their bodies against something.They usually use sleeping bags located in small crew cabins （乘员舱）.Each crew cabin is just big enough for one person.Generally，astronauts have an eight﹣hour sleep each day when they finish their task.
• Doing sports in space
Exercise is an important part of every astronaut's daily life to prevent muscle loss （肌肉萎缩）.Usually，astronauts exercise two hours every day.Lifting 200 pounds on the earth may be a lot of work.But lifting that same object in space would be much easier.That means the things for exercise need to be specially designed，so astronauts can receive the exercise needed.
Living in space is not just all work and no play.Astronauts have fun，too.They like to look out the window and play with their food.Fun plays an important role in the quality of their life.

The first emperor of China，Qin Shihuang，completed a huge number of projects during his rule.Between 221 and 210 B.C.，he started the building of the Great Wall.The emperor also ordered the building of a huge army of life﹣sized terracotta soldiers（士兵）.These，he hoped，would protect his tomb after his death.
Lost in Time
The soldiers in Xi'an's terracotta museum are today light brown，but they weren't always.They began as an army of red，blue，yellow，green，white，and purple.Sadly，most of the colors did not last to the present day.After being exposed（暴露）to air during digging，the coating under the paint began to fall off.The paint disappeared in less time than it takes to boil an egg，taking away with it important pieces of history.
New Technology
Now new technology is starting to show the army's true colors.Archeologists（考古学家）have recently discovered an area with more than a hundred soldiers.Many of these still have their painted features，including black hair，pink faces，and black or brown eyes.Chinese and German researchers have developed a chemical liquid（液体）to help save the soldiers' colors.After finding a soldier or another art piece，archeologists put the liquid on it. They then cover it in plastic.
Back to Life
Archeologists are also finding colors in the dirt around the soldiers.It's important not to do anything with the dirt，so the colors won't be lost. "We are treating the dirt as an art piece， "says Rong Bo，the museum's leading archeologist.The next challenge，says Rong Bo，is to find a way to use the colors onto the army﹣again.Once that happens，artists can bring Emperor Qin's army back to its full，bright colors.

A small cloud moves slowly through the air in a hospital operating room （手术室）.In the room a patient with cancer（癌症），lies on a table.The cloud is all around the patient，covering her body and filling her lungs（肺）.The cloud is not smoke.It is made of millions of nano﹣robots（纳米机器人）.These tiny robots move from cell （细胞） to cell in the patient's body，killing the cancer.
Fighting cancer with nano﹣robots is only an idea today，but scientists say that it could be possible in the future.Using nano﹣robots for good purposes such as fighting the illness or repairing the environment may be the way to many of today's problems.
However，nano﹣robots could be a dangerous risk as well.Because nano﹣robots are so tiny，they will have to work in large teams of many thousands to many millions.For this reason，nano﹣robots will have to be programmed（被编程）to build themselves.Scientists will not have the ability to build millions of nano﹣robots one by one.
This ability to re﹣produce is making some scientists worried.What will happen if something goes wrong in the programming？Quite a lot of crazy nano﹣robots would be far worse than any illness.Some people think that if they get out of control，nano﹣robots could make the Earth gone.
