Online Event：What Happened at the Big Bang（爆炸）？
Over the past few decades, we've made unbelievable discoveries about how our universe developed over the past 13. 8 billion years. But we still know very little about what happened in the first seconds after the big bang.
In the latest New Scientist online event, the speaker Dan Hooper will examine how physicists are using experiments to re-create the conditions of the big bang, and to deal with mysteries like how our universe came to contain so much matter and so little antimatter.

I woke at 5:30 A.M. after a restless night’s sleep. I slowly unzipped the tent door to inspect the new day. Just like yesterday, the wind had dropped. It was another beautiful Arctic day. I crawled out of my sleeping bag unwillingly. I am normally a morning person but the intense cold outside made that morning most unappealing. Anyhow, it was time to greet Charlie and start the day.
My dog Charlie was up and it was bouncing up and down at the end of his chain looking well rested. I poured what looked like a pound of dog food into his bowl.
Stepping out of the tent, I looked around for bears or tracks and saw none. It would never be a good thing to meet a polar bear. An Inuit (因纽特人) once told me that I should watch out for polar bears. He said that if I met a polar bear, I should keep the following rules in mind. First, keep eye contact, move sideways or slightly forward, never backward, stay calm. Do not show fear and stand beside a large object to make myself appear as large as possible. Weapons like flare gun(信号枪) are necessary, but do not shoot unless forced to. Don’t wound a bear, or you'll make it even more dangerous, and never run.
It was only six o’clock, so I decided to have a leisurely breakfast of a bowl of milk powder, coconut flakes, and butter mixed with warm water. I sat on my sled（雪橇） to enjoy my first breakfast of the expedition only to find that after the third spoonful it was frozen. So much for leisurely breakfasts! I added more warm water and ate the rest as fast as possible.
Suddenly I heard a deep, long growl coming from Charlie’s throat. In a flash I looked at him and then in the direction in which he was staring. It was a female polar bear followed by two cubs（幼崽） slowly, purposefully, toward me. They were two hundred yards away.
Paragraph 1:
With my heart quickening, I grabbed my loaded flare gun and carefully walked sideways a few steps to Charlie.

As our Earth’s temperature warms up because of climate change, it is having unexpected effects on our world’s forests. When temperatures rise, trees close their skins to ___________ the loss of water, and this, in turn, slows down the ___________ of photosynthesis(光合作用). As a result, these trees are shorter and grow slowly, as well as have a ___________ death rate.
Climate change also increases the ___________ of droughts and wildfires. After wildfires, it takes a while for the forest systems to ___________ , and in some cases, the forests are ___________ permanently. Trees that are stressed are also ___________ to attacks by bacteria(细菌). In tropical forests, vines that use the trees as ___________ can often choke the trees and rob them of nutrients. Finally, humans have ___________ the forest landscape through logging. When trees are replanted on the soil, they will never grow as large as the ____________ trees that were cut down.
As these forests disappear, species that once called them “home” are forced to change, ____________ the variety of those systems. ____________ , some endangered species are unable to ____________ and die. Old-growth forests are disappearing in all regions of our world. When forests die, younger forests that are reestablished in the same area grow back weaker and smaller ____________ poor vegetation. With trees dying increasingly and continuously, will future generations ____________ out on the wonders of forests?

Being able to communicate effectively with others is an essential skill for people of all ages. 1. People who want to develop those skills can learn how to do this from self-help books, workshops, and from the advice of other people.
2. Active listening involves a person listening carefully and attentively to the person speaking, restating what the other person has said — or what comes across — in a brief and nonjudgmental manner. 3. Becoming effective at active listening is one way to increase trust and understanding in a relationship, whether it is a personal or professional one.
Another tip to developing and improving interpersonal communication skills is to use feedback for different types of communication. Before giving speeches and presentations, it is always well advised to practice them before an audience and to ask for feedback before giving the real speech or presentation. 4.
It also is essential in developing communication skills to use appropriate body language and eye contact. 5. For example, using direct eye contact and body language that indicates openness, such as uncrossed arms, can help to get across that a person is ready and willing to listen and to speak openly.
A.It is essential to learn how to communicate politely.
B.These nonverbal signals can convey the true feelings.
C.Most people can benefit from improving their communication skills.
D.Being active listening doesn’t mean people have to employ it continuously.
E.This kind of listening focuses more on understanding than on giving advice.
F.By doing so, we can ensure the messages are easily understood and come across as intended.
G.One of the best tips for developing communication skills is to learn and practice effective listening.
Tell a child they need to experience another painful medical procedure, and you’ll probably have a kid filled with fear and anxiety. Tell that same child they’ll have a chance to strike flying cheeseburgers in outer space while their doctor works on them, and they might feel a little different.
That night-and-day difference in how kids respond to the treatment of their doctors is the reason for Lucile Packard Children’s Hospital Stanford’s innovative use of virtual reality technology. Packard Children’s lets kids participate in experiences that can significantly reduce their anxiety — and even their pain.
This isn’t the first time Packard Children’s has introduced those innovative methods. In 2015, Thomas Caruso, M.D., the founder of Packard Children’s Childhood Anxiety Reduction through Innovation and Technology (CHARIOT) program, introduced the Bedside Entertainment and Relaxation Theater (BERT). The system projects videos on a large screen attached to patients’ gurneys(装有轮子的床) so they can watch movies and music videos all the way to the operating room. And in early 2017, CHARIOT launched an interactive video game called Sevo the Dragon, which projects on the BERT screen, so the tiniest patients have something fun to do while breathing medicine through a mask.
“Children shouldn’t grow up being afraid to go to the doctor to have a shot, but certain experiences can cause strong unreasonable fear that last into adulthood. Needle phobia(晕针) is a common example of that, and it is the primary reason adults avoid important immunizations(免疫) like flu shots.” Caruso told Stanford Medicine News Center.
VR distraction therapy is being used for kids at Packard Children’s as young as age 6 in specific areas like the emergency department, and the tool will be widely used in all of the Children’s Health’s surgery clinics by the end of 2020.

2.What is the purpose of the CHARIOT program?
