지난 1월 3일 한국에서 시험볼때, 새로운 Retell lecture 문제가 나왔었는데,

관련 자료를 찾아서 공유드립니다. 한번 읽어보시면 시험때 당황하지 않으실 꺼에요!!

Large Hadron Collider (that big blue tube) is a particle physics scientist in order to explore new particles, and micro-quantification of particles 'new physics' mechanism equipment, is a proton accelerated collisions of high-energy physics equipment, the English name For LHC (Large Hadron Collider).
 

The European Large Hadron Collider is the largest and most energetic particle accelerator in the world today. The Large Hadron Collider is located in a tunnel that is 100 meters deep beneath a 17-mile (including circular tunnel), Switzerland, French border near Jurassic. On September 10, 2008, the collision detector was first tested. 


In 2010, scientists involved in the Large Hadron Collider (LHC) project said they may have "approached" the Higgs boson. The Higgs Boson, also known as the "God Particle," is said to play an important role in shaping the universe after the Big Bang. April 5, 2015 After a shutdown and maintenance of about two years, the European Large Hadron Collider was restarted and the second phase of its operation was officially launched with the hope of exploring the discovery of the existence of supersymmetric particles of the Higgs-coupled particles .



Here's a summary of knowledge according to candidates memories points :

Physicists at CERN in Geneva have achieved the first 7 TeV proton-proton collisions at the Large Hadron Collider. The LHC consists of a 27-kilometer ring of superconducting magnets with a number of accelerating structures to boost the energy of the particles along the way. The electromagnets are built from coils of special electric cable that operates in a superconducting state, efficiently conducting electricity without resistance or loss of energy. Here requires chilling the magnets to -271.3 ° C - a temperature colder than outer space. The collider has four crossing points, around which are seven sensors, each designed for certain kinds of research. The LHC to collides proton beams, but it can also use beams of heavy ions.

감사합니다. 헐 내용 너무 어렵네요 ㅠ

신기출이 계속 추가되네요ㅜㅜ 감사합니다

Congratulation! You win the 45 Lucky Point!

이문제 제가 쳤던  지난 11월 시험에 났어요. 그때 이미 기출문제에 올랐었고 내용도 알고 들어간 상태에서 시험을 봤는데도 엄청 어렵더라구요. 녹음에 잡소리도 들어있고 엄청 빠른 속도로 말하고 전체 길이가 1분도 안된걸로 기억합니다. 이제 시작했다 싶었을때 이미 끝나 있었죠... 이문제는 그냥 시험에서 안만나는게 최선인것 같아요...

호주 무역관련 RL 소스를 구하고 싶은데, 유트브에서 구하기 힘드네요 ㅠㅠ 중국관련만 있고 ,,,

혹시 Australian Export - with Asia and USA 소스를 찾고 계신가요? 현재 음성파일은 없고 문장형식으로만 리코드한 예문들이 있어요.
The lecture talks about China, japan, US's export business.
In the past, Australia was concerned about its geographical location, which may result in Australia being isolated from North America, UK, and later America.
Nevertheless, nowadays with the rise of Asian countries, especially China, Australia has become a great export country with a perfect location.
Currently, Japan is the largest exporting country to Australia, but China may become the largest one in the future. Australia should take the advantage of China's raise to develop its exports.
참고가 되였으면 좋겠어요.

허허 어제 시험에서 출현했어요 ㅠ 덕분에 당황하지는 않았지만 생각보다 너무 못알아듣겠어서 정말로 많이 어려웠습니다. 과학 관련 지문은 때론 지식이 있어도 답하기가 많이 어렵네요 ㅠ

저도 1월11일에 나왔었습니다. 진심 패닉이었어요 .,....

1월 30일에 이 문제가 또 나와서 여러 기출 자료를 보다가 키워드를 정리해 보았습니다
1. Large Hadron Collider also is know as LHC - The world's largest and most powerful particle accelerator
2. It has 27km tunnel with 7Tev release energy, results in 14k times collision
3. proton light, particle released
4. It helps to have a better understanding of universe in the early history
5. 1.9K(?) is operating temperature which is the absolute zero
