My name is John and I must share with you an event which took place on Flight 1553 out of DCA. My wife and I were traveling to Miami to celebrate an achievement for her and as you can imagine, we were looking forward to fun, sun and laughter.
We boarded the aircraft, without a care in the world. It was cold in Washington and we were ready for Florida.
Shortly after taking my seat, I began to feel sick. I knew something wasn’t right but just couldn't find out what was happening.Being a doctor and a stubborn man, I resisted efforts by my wife to call for assistance. As the aircraft began its departure roll, I lost consciousness for a short amount of time.
As I came around, I quickly realized a few things. Firstly, something very bad had happened to me. Secondly, the aircraft was too heavy with the fuel to go back home. Thirdly, my loss of consciousness had been so deep that I found myself out of control. So not only did I have a medical issue to deal with, but I also had to figure out how to deal with an embarrassing experience.
My wife gathered the crew as soon as it was safe to move about and I made my way to the washroom to attempt to clean up. I did my best and the flight crew members were so supportive, checking on me often and reassuring me that there was nothing to be embarrassed about.
It was their sympathy and support that helped me so much. During the flight they kept watching over me and I suddenly had a small group of nurses, bringing blankets, food, drinks and caring and smile. I was thankful to them.
Paragraph 1：
Upon landing, I remained in my seat, allowing other people to go first.

Following the outbreak of the novel coronavirus pneumonia (NCP), also named COVID -19 by WHO, there is a general fear of the unknown virus as its full effects remain to be seen. Fever, coughing, sore throat, difficulty breathing – the NCP’s symptoms are similar to the common cold or the flu, but it’s potentially more dangerous.
Viruses could be deadly, like HIV and Ebola. 1. How can they cause so much trouble?
Viruses are non-living organisms approximately one-millionth of an inch long. Unlike human cells or bacteria, they can’t reproduce on their own. Instead, they invade the cells of living organisms to reproduce, spread and take over.
Viruses can infect every living thing – from plants and animals down to the smallest bacteria. 2. Sometimes a virus can cause a disease so serious that it is fatal. Other viral infections bring about no noticeable reaction.
Viruses lie around our environment all of the time, waiting for a host cell to come along. They can enter our bodies by the nose, mouth, eyes or breaks in the skin. 3. For example, HIV, which causes AIDS, attacks the T-cells of the immune system.
But the basic question is, where did viruses first come from? 4. “Tracing the origins of viruses is difficult,” Ed Rybicki, a virologist at the University of Cape Town in South Africa, told Scientific American, “because viruses don’t leave fossils (化石) and because of the tricks they use to make copies of themselves within the cells they’ve invaded.”
However, there are three main theories to explain the origin of viruses. First, viruses started as independent organisms, then became parasites (寄生者). Second, viruses evolved from pieces of DNA or RNA that “escaped” from larger organisms. Third, viruses co-evolved with their host cells, which means they existed alongside these cells.
5. The technology and evidence we have today cannot be used to test these theories and identify the most plausible explanation. Continuing studies may provide us with clearer answers.
A.But what are viruses?
B.For the time being, these are only theories.
C.Once inside, they try to find a host cell to infect.
D.The answer may be even less satisfactory than it now appears.
E.Until now, no clear explanation for their origin exists.
F.Experts are concerned about the bad effect that it had on people’s health.
G.For this reason, they always have the potential to be dangerous to human life.
On the summer of 1995, a second-year graduate student named Sergey Brin was giving a tour of Stanford University to prospective students. Larry Page, an engineering graduate from the University of Michigan, was one of those being shown around the campus.
“We both found each other obnoxious and annoying with strong opinions about things,” said Brin. “But we said it a little bit jokingly. Obviously, we spent a lot of time talking to each other, so there was something there.”
The technology of the web at the time meant that people could tell where a webpage linked to just by reading its code. However, to get a complete list of every page to which it linked, they needed to check every other website on the Internet.
Page’s “BackRub” project aimed to qualify these backlinks (反向链接). It was a complex task that not only demanded vast computing resources, but also required extremely complex mathematics, which was where the math genius Brin came in.
Later, Page and Brin came up with the PageRank algorithm - a ranking system which would prove to be a breakthrough idea. And then, BackRub became Google, a play on the term “googol,” meaning “10100.” The system successfully enabled users to search all 24 million pages stored in its database.
On September 15, 1997, Google.com was registered. In August 1998, it got its first funding in the form of a check for $100,000 written by Andy Bechtolsheim, co-founder of Sun Microsystems, to “Google Inc.” But still there were troubles. Later that month, Page and Brin moved into the garage (车库) of friend Susan Wojcicki (now the CEO of YouTube), and received further investment from Amazon founder Jeff Bezos, among others.
Early in 1999, Page and Brin attempted to sell Google to Excite, at the time the No. 2 search engine behind Yahoo, for one million dollars. However, even after the pair had been talked down to $750,000, Excite CEO George Bell rejected them. With no buyer in sight, Google started hiring engineers and moved to an office in California in March 1999. In 2001, Eric Schmidt was hired first as chairman and then CEO, leaving Page and Brin to continue developing Google’s products and technologies respectively. By the end of its first decade, Google had effectively won the search engine wars.
