Every event here features a noted scientist who discusses a different cosmic （宇宙的）topic.They will be presented with a livestream to our Science World official website and questions can be asked in the website chat.
Black Holes
7：30 PM-8：30 PM，May.19，2023
Description：Most galaxies（星系）have a supermassive black hole at their center.These black holes help determine how galaxies will develop over time.Join Dr.Ansel Netscher for an outline of black holes.You can also explore how supermassive black holes may decide the development of galaxies.
The Webb Imagery
8：00 PM-9：30 PM，May.28，2023
Description：The amazing visions have attracted the world.But there's a long and involved process by which scientists' black-and-white observational data is transformed into dynamic color imagery for the public.Join image specialist Ralph Wilson as he discusses the art and science of translating infrared light.
Hunt for Distant Worlds
7：00 PM-8：00 PM，Jun.3，2023
Description：Since the discovery of the first planet orbiting a Sun-like star in 1995，more than 4，000 exoplanets have been found.These widespread planet systems confirm that our solar system is just one of many in our Milky Way galaxy.The discovery of such systems has provided interesting insights，challenging our views about how planet systems form and develop.Join Dr.Amanda Garcia as she describes the scientific hunt for these distant worlds.
Mars and Beyond
10：00 AM-11：30 AM，Jun.4，2023
Description：Will we ever reach Mars？And what will it take to travel to other stars？Dr.Camille Lopez will meet these questions with a speech of what we can expect in the next 30 years.It's based on what is practical and reasonable when we consider the biological，economic，and philosophical concerns that connect with the engineering challenges of.jye.ai habitation and exploration.

1．China plans to complete the construction of a space station and have（1）
put into operation around 2022，said Zhou Jianping，the chief designer of China's manned space program，at a forum（論壇）（2）（hold） in south China's Guangdong Province．The space station（3）（design） to weigh 100 tonnes and accommodate three astronauts，（4）could be enlarged if needed，according to Zhou．
"The main goal of the construction of the space station is to enable China to become a country（5）（independent） mastering the technology for long term manned flight in near Earth space，and having the capability to carry out long-term manned scientific（6）（experiment） in near Earth space and comprehensive development and utilization（利用） of space resources，"（7）（say） Zhou at the 4th China Summit Forum on Human Factors Engineering，which was held at Sun Yat-sen University from Saturday to Sunday，
The space station will be built as China's main platform for space science research，（8）the intention of mastering the technologies in constructing and（9）（operate） large space facilities，the technologies that guarantee life and health of astronauts who often fly in orbit，and the construction of a（10）（nation） space lab，according to Zhou．發(fā)布：2024/12/6 8:30:1組卷：22引用：5難度：0.7 -
2．In 1969，when Neil Armstrong first landed on the Moon，many people thought soon we would be regularly visiting other planets.（1）
The reality is that space exploration is extremely difficult and dangerous.Some people believe it is a waste of the public purse and does nothing to improve our lives.Why do we continue to explore space，then？
（2）From the very early days of human life on the Earth，our curiosity about the unknown has kept us adventuring into new places.While space exploration is a reality，we remain curious about the mysteries of the universe.With each space mission comes greater insight，thus motivating us to continue along the same path of adventure.
With technologies developed for space exploration，we can solve some big problems facing mankind，making our lives safer and easier.（3）Originally applied to the space shuttle launch，they have also been set up in the cities with a high frequency of earthquakes to protect buildings and save lives.
Although space exploration demands huge investment，it can actually bring great economic value.The global space economy is increasing by billions of dollars every year.（4）Jobs in the space industry go far beyond the astronauts.There are many support staff on the ground，such as engineers and research assistants.
Moreover，the amazing work can provide education and inspiration for the next generation.Such wonders as a space shuttle launch or astronauts walking on the Moon are incredibly inspiring to witness.These moments shape children's lives forever and motivate them to become the scientists and engineers of the future.（5）
A.This is clearly not the case.
B.It is in our nature to explore.
C.The universe is too mysterious to explore.
D.One of these is earthquake shock absorbers.
E.It can also provide a variety of career opportunities.
F.These scientific and technological advances can benefit societies in many areas.
G.When you've seen a man walk on the Moon，you grow up believing anything is possible!發(fā)布：2025/1/1 16:30:1組卷：5引用：2難度：0.5 -

（look） up at the stars，people have always wanted to learn more about space，and scientists work hard to explore space.On 12 April，1961，Yuri Gagarin became the first person in the world （2）（go） into space.Over eight years later，on 20 July，1969，American astronaut Neil Armstrong stepped onto the moon，famously saying，"That's one small step for a man，one giant leap for mankind." Following this，many more goals （3）（achieve）.
（4）scientists try to make sure nothing goes wrong，accidents can still happen.All the（5）（astronaut）on the USSR's Soyuz 11 and America's Challenger died during their missions which made everyone sad and （6）（disappoint）.Despite the huge risks，people carry（7）exploring space.
China's space programme started later than those of Russia and the US，but it（8）（make）great progress in a short time.China became the third country in the world to （9）（independent） send humans into space in 2003.Now China as well as Europe and the US has plans to further study and explore plants like Mars （10）Jupiter.發(fā)布：2025/1/1 5:0:1組卷：4引用：2難度：0.5
