China launched a large robotic spacecraft on Nov.24,2020 at the Wenchang Space Launch Center in South China's Hainan province,tasking it with landing on the moon and bringing back lunar samples,44 years after the last time such substances were brought back to Earth.
If everything proceeds smoothly,about 2 kilograms of stones and soil will be collected and packed in a vacuum metal container.The entire mission is scheduled to last about 23 days,according to the China National Space Administration.Considering these highly sophisticated operations,Chang'e 5 will be more difficult and challenging than previous Chinese lunar expeditions,designers have said.
According to a statement published by the space administration,the Chang'e 5 mission is intended to fulfill several objectives.In terms of space engineering,it will demonstrate technical plans and apparatus for autonomous lunar sampling and packing and moon-based launching,as well as lunar orbital dockjye.aig.In the scientific field,it will investigate the landing site's features,and enable scientists to analyze the lunar samples' structure and physical traits so they can deepen their research into the moon's origin and evolution.It added that the mission also will help to foster the country's knowledge,technology and talent pool for its future manned missions to the moon and other deepspace expeditions.
Pei Zhaoyu,spokesman for the Chang'e 5 mission,said if the mission becomes successful,it will be a milestone in the nation's lunar exploration and will show the world China's scientific,technological and engineering capabilities.
Furthermore,Chang'e 5 will strengthen the nation's status and influence in the international space community,pave the way for the country's future lunar expeditions and boost its space science,and will offer more opportunities to lunar researchers around the world.Scientists around the world are welcome to participate in the research related to the lunar samples brought back by the mission.China will publish a set of guidelines about the use and distribution of the samples after the mission.

1.British children's writer Roald Dahl ate chocolates and sweets "pretty much every mealtime",remembers daughter Ophelia Dahl.
After dinner,whether dining alone or entertaining guests,Dahl would pass around a little red plastic box full of Mars Bars,Milky Ways,Maltesers,Kit Kats and much more.
He knew the history of all the sweets and could tell you exactly when they were invented. =1937 was a big year when Kit Kats (his favorite),Rolos,and Smarties (his dog,chopper's favorite) were invented.He wrote a history of chocolate,lecturing schoolchildren to commit such dates to memory,such as 1928 when "Cadbury's Fruit and Nut Bar popped up on the scene",saying don't bother with the Kings and Queens of England.All of you should learn these dates instead.Perhaps the Headmistress will see from now on that it becomes part of the major teaching in this school.
According to Dahl,the Golden Years of Chocolate were 1930-1937.In 1930,Roald Dahl was 14 years old.He was a student at Repton,a famous boys' boarding school in England.It was a tough environment:Those in authority were more interested in controlling than educating the students.
Ironically,it was at this difficult period that chocolate became Dahl's passion.Near Repton was a Cadbury chocolate factory.Every so often,Cadbury would send each schoolboy a sampler box of new chocolates to taste and grade.They were using the students - "the greatest chocolate bar experts in the world" to test out their new inventions.
This was when Dahl's imagination took flight.He pictured fiactories with inventing rooms with pots of chocolate and fudge (軟糖)and "all sorts of other delicious fillings bubbling away on the stoves".
"It was lovely dreaming those dreams…when I was looking for a plot for my second book for children,I remembered those little cardboard boxes and the newly-invented chocolates inside them,and I began to write a book called Charlie and the Chocolate Factory."
For the record,Roald Dahl did not like chocolate cake or chocolate ice cream.He said, "I prefer my chocolate straight."

2.Hannah Levine decided she wanted to give hugs to all of the children and families in need at local hospitals.
Because she couldn't give them hugs one by one,Levine,then a sixth-grader,decided she would use her talents (才能) to do the next best thing.She began to knit (編織) hats,scarves,and blankets for families staying at the Ronald McDonald House at Stanford.Her creations also went to Bundle of Joy,a programme that provides newborn baby items for families in need,and to Knitting Pals by the Bay,a local organisation that provides hand-knitted caps to cancer patients.
"I love to knit,and I thought it would be a great idea to make all these handmade items for kids and adults who need them.It would be like a hug for them," Levine explained.
Levine started the project about a year ago. "I think it's just really fun to do,and it keeps me busy," said Levine,now 13.
Once she got started,Levine realised that her project could be much bigger than the goods she was able to produce with just her own hands.So she sent emails to her school and communities,asking for knitted donations (捐贈物) to the project,she named "Hannah's Warm Hugs".She also posted advertisements at Starbucks and other locations in her area.The warm goods began to pour in.
"It was amazing;more strangers than people she knew started dropping donations at our door," said Levine's mother,Laura Levine. "We ended up with this huge box of items she was donating."
The knitted items numbered in the hundreds.Levine made her first round of donations around Hanukkah (an eight-day Jewish holiday in November or December) and later received thank-you letters from the organisations.Levine is still knitting,and she said the project will continue.
"It has turned into a bigger thing than she had thought," her mum said. "It made her feel pretty good;it made us feel pretty good."

3.LANZHOU-When an international olive oil competition announced its winners in Greece in late June,excitement spread across the village of Daoqi in Northwest China.
"The award-winning olive oil was made from our fruit," said Ru Ciming,50,an olive planter from the village under the city of Longnan,Gansu province.The variety of olive trees in Ru's orchard(果園)was introduced from Spajye.ai.In the eyes of locals,the foreign trees have not only pulled the city,once among the least-developed regions in China,out of poverty,but they have also brought them international fame.
Olives originated in the Mediterranean(地中海地區(qū))and their oil,often called liquid gold,is used widely in food,cosmetics and medicjye.aie.In the 1960s,the Albanian government gifted China more than 10,000 olive saplings(樹苗),which were then planted in many parts of the country on nationwide trials.Longnan began to plant olive trees in the early 1970s and experts concluded that the region was ideal for the resettlement of the olive trees due to its climate and soil condition.After years of experiments and promotion,it is now the largest olive cultivation(栽培)base in China.
In recent years,the local olive oil industry has continued to expand as Longnan has improved cooperation with Mediterranean countries that have a long history of olive planting,including Italy,Greece and Spain.The improved cooperation aims to introduce better varieties and initiate technical exchanges.
Pedro J.Rodriguez Sanchez,a Spanish olive seedling expert,was one of the early contributors to olive exchanges.He arrived in Longnan in 2009,when only half of the local olive tree seedlings had survived.His technical guidance helped raise the survival rate to over 90 percent.
Zhao Haiyun,an official in charge of promoting the olive industry in Longnan's Wudu District,said that many more European experts have arrived since Sanchez.They have visited orchards to offer guidance to farmers,and helped companies improve their processing and storage procedures.
They have helped the district,as well as the city of Longnan,to jump on the bandwagon of China's rising demand for high-quality olive oil,especially among well-off urban families,said Zhao.
(1)What can we learn from the third paragraph?
A.Olive oil is named liquid gold and has many uses.
B.The Albanian government sold some olive saplings to China.
C.Longnan has a history of about 30 years of planting olive trees.

(2)Where did Pedro J.Rodriguez Sanchez come from?
A.Italy.
B.Albania.
C.Spain.
D.Greece.
(3)Which of the following words can replace the underlined one "bandwagon" in the last paragraph?

B.Habit.
C.Fashion.
D.Model.
(4)What can be the best title for the news report?
