During the outbreak of novel coronavirus, cities are locked down and borders are closed. Science, on the contrary, is becoming more open. And this "open science” is already making a difference.
Soon after the epidemic started in China, a research team from Fudan University in Shanghai successfully sequenced （测定序列）the DNA of the virus. But they didn't keep the information to themselves. Instead, they placed the sequences on GenBank, an open-access data platform, so researchers around the world could download them for free and start studying the virus.
Due to this openness, pharmaceutical companies across the globe arc now able to work at the same time to develop a vaccine （疫苗）."There may be room for multiple different vaccines for different purposes and different age groups,” Amesh Adalja, a senior scholar at the Johns Hopkins University Center for Health Security in the US, told Al Jazccra. "The bigger menu we have of vaccines, the more resilient （有 适应 力的）we'll be against coronavirus outbreaks in the future."
Major drug companies around the world arc also sharing their study results. Remdesivir, a drug originally developed by US company Gilead Sciences to treat Ebola, is found to be promising in fighting against the novel coronavinis. Currently, two trials of the drug arc already underway in China, and the results might be available as soon as April, according to The Verge.
This openness in science is going to be even more important in the future. “With climate change, increasing globalization, and population shifts, epidemics will not go away, and might even become more frequent,” Dan Barouch, a Harvard Medical School professor, told Harvard Magazine.
He said, “No one group can do everything. It has to be a coordinated approach. But I do think that the world has a greater sense of readiness this time to develop knowledge, drugs, and therapeutics （疗法）very rapidly.”
Every epidemic is indeed a crisis, but it can also be a learning opportunity. One redeeming （补偿的）factor of the COVID-19 outbreak is that it is helping science adapt for the better.

Due to the outbreak of the novel coronavirus pneumonia （NCP）, people all over the world are wearing masks to reduce the risk of infection. It's a very simple but incredibly effective method to protect oneself from a variety of harmful things. In fact, masks have been helping mankind for centuries. Let's take a look at some mask-related history.
1st century
In that era, many people in Roman Empire worked underground in mines to support their families. But most of them suffered from and even eventually died of respiratory （呼吸的） illnesses. To address this problem, Pliny the Elder （23-79 AD）, a Roman philosopher and naturalist, recommended the use of animal bladder （膀胱）skins to stop dust from being breathed in. Although primitive, his idea was considered the very first recorded mask invention.
16th century
Early inventions did not stop with Pliny. Many centuries later, Italian artist and inventor Leonardo da Vinci （1452-1519）, proposed using a woven cloth dipped in water over the face to protect against the poisonous chemicals.
19th century
The design of the mask look a big step forward in the 19th century. In 1848, American Lewis Hassley became the first person to patent （注册专利）a protective mask for miners, which was a milestone in face mask history. Masks at this stage were similar to gas masks. Later, in 1897, Polish-Austrian doctor Johann von Mikulicz-Radccki designed a simple mask composed of one layer of gauze （纱中1）, recommending medical workers to wear it to prevent infection. That was the first recorded use of a surgical mask.
20th century
In 1910. an epidemic broke out in Northeast China. Chinese doctor Wu Liande designed a cheap face mask called "Wu's mask". Made of two layers of surgical gauze, it could be wrapped around the back of the head and tied in a knot. This mask was praised by experts around the world, as it was simple to manufacture （制作）and had a low production cost. Modem exploration
With several outbreaks of infectious diseases and the flu. and the rise of pollution caused by industrial waste, the materials in masks have continued to evolve to better protect its wearer. For example, in 2012 when China suffered from smog, mask models such as N95 and KN90. which can filter out this fine particulate （微 粒）mailer, became highly popular. In the future. masks will continue to improve, hopefully so will the habits of humans.

A couple of weeks ago, my grandfather was explaining his favorite expression. "Nothing is ever easy? The following day, as I tried to complete my day's work, I happened to notice a bumblebee（大黄蜂）on the skylight（天窗）.The skylight was particularly high up, but I thought removing the bee would take no more than five minutes. An hour later, the bee still remained. All that had changed was that the living room was a mess and that 1 was dizzy from looking up into the sunlight. I did not expect to waste an hour on an insect so tiny, but by doing so, I understood what my grandfather meant.
It is not only time that we tend to underestimate — we don’t account for unexpected costs. We often imagine what can work in our favor but we seldom think of all the negative things that could a fleet us. However, it is important to remember that your day or week or year might nor go as planned, and that is completely normal. It is perfectly acceptable to feel challenged — even at a task you thought was simple — because that is part of life.
If you can accept that nothing will ever be easy, then life might seem slightly more manageable. In middle school. I thought high school might be easier because I could choose the classes I wanted to take. In high school I thought college might be easier because I could have a schedule（计划）best suited for myself. Yet each time, I was both wrong and disappointed. After accepting that school wouldn't（and shouldn't）be easy. I found myself with a more positive altitude and improved results.
Of course, there should be preparations made to account tor expenses or time. Doing so can only help you accomplish your goals in a better way. However, there is no need to beat ourselves up when something stands in our path. Maybe we cannot see a bee coming our way, but we can always give ourselves the extra time to catch it.

A.To share something unforgettable with us.
B.To lead us to what the author learned from it.

D.To tell us how easy it is to waste our rime.
2.Why do things often tum out to be different from what we expect?
A.We often don't take lime seriously.
B.We tend not to have enough money.
C.Unexpected things can happen.
D.It is easy to feel challenged.
3.According to the text, what does the underlined phrase "beat ourselves up" mean?
A.lo hit or kick ourselves hard, many times
B.to blame ourselves too much
C.to encourage ourselves to work hard
D.to give up ourselves
4.What is the author's purpose of writing this article?
A.To encourage people to make greater efforts.

阅读短文，按照题目要求用英语回答问题。
As any younger brother will tell you, having a big brother involves a lot of walking in someone else’s shadow, especially when you have a brother who is a typical example of “cool”. For years I wanted to do everything my elder brother Tyson did, but no matter how hard I tried, I was always the neglected (被忽略的) one. My legs just weren’t made to run like his. I could never play football or basketball well.
I probably would have continued trying to keep up with him for the rest of my high school career, but when my family moved, everything changed. Tyson left for college, so I had to start at a new school all by myself. This new start gave me an opportunity to redefine myself and discover an entirely new version of “cool”.
I don’t know what made me decide to try some new activities at the new school, but one day I chanced to show up for an after-school meeting of the Science Olympiad team. I had always been fascinated with chemistry, biology, and math, but since those interests hadn’t fit Tyson’s definition of “cool”, I had never pursued them. On this day, for some reason, I did.
As we organized teams, prepared resources and practiced answering questions, I felt more connected than I ever had to any sports team. I didn’t feel as though I needed to keep up with anybody else; I was finally with peers who understood me. It was so good to feel accepted for what I’m good at. For the first time in my life, I actually felt cool. Now I know who I am! I’m Tyson’s little brother, but that’s only part of my identity. I’m a cool guy in my own way, too. I’m relieved to know that “cool” has a much broader definition than what I used to think.
