Researchers Are Racing to Make a Coronavirus Vaccine. Will It Help?
In the early days of January, as cases of a strange, pneumonia-like illness 1.(report) in China, researchers at the National Institutes of Health 2.(ready) themselves to hunt for a vaccine to prevent the new disease.
Scientists in Australia are also working on vaccine candidates to stop the spread of the disease. 3.(historical), vaccines have been one of the greatest public health tools to prevent disease. But even as new technology, advancements in genomics and improved global coordination have allowed researchers to move 4. unprecedented speed; vaccine development remains 5. expensive and risky process.
It takes months and even years because the vaccines must undergo extensive testing in animals and humans. 6. the best case, it takes at least a year — and most likely 7.(long) — for any vaccine to become available 8. the public.
With each new outbreak, scientists 9.(typical) have to start from scratch. After the SARS outbreak in 2003, it took researchers about 20 months from the release of the viral genome to get a vaccine ready for human trials. By the time an epidemic caused by the Zika virus occurred in 2015, researchers 10.(bring) the timeline down to six months. Now, they hope the joint efforts will cut that time in half.
When I was a child my father taught me five words that I’ve used all my life—in my acting career, as a mother, in my business activities. If I _______ that I was afraid of the dark, or if I seemed worried about meeting new people, Dad would say, “Stand porter to your _______.”
A porter is a gatekeeper, who stands at a door _______ people in or out. Dad would get me to _______ myself stopping destructive things—such as fear—at the door, _______ saying “Come in” to faith, love and self-assurance.
As a(n) _______, before I went on camera, I’d make sure anxiety stayed out and confidence in my ability came in. As a mother, when I was _______ about my children, I would try not to let worry in but would _______ my mind with trust in them.
Of course, there were always times I’d _______ those words.
In 1972 my husband, Fillmore Crank, and I opened the doors to our own __________ in North Hollywood. This was a new business venture for us, and it was a lot more __________ and complicated than we had __________.
We were on call 24 hours a day. Something was always going __________. Electricity went on the blink, food wasn’t delivered, employees called in sick. Once, a flu epidemic __________ left us with no maids. Fillmore gave me a __________: scrub floors or do the laundry. For 10 days I folded enough king-size sheets to __________ the whole state of California.
Then there was the __________ crisis. The price of gasoline doubled, and tourism in California __________. How could we fill our beds? What if we kept losing money? What if we failed? Fear and worry were sneaking in. But I caught them just __________. I stood porter.

How to keep yourself safe from new virus?
After a new-type coronavirus was detected in viral pneumonia cases in Central China's Wuhan city a month ago, more cases have been reported in recent days. To prevent catching the infection, here’s what you can do:
1. Wear masks outdoors
●Wearing a mask is one of the most effective ways to protect you from getting infected.
●1.
●If you’re not feeling well or have symptoms of fever, a mask is also needed to prevent you from spreading germs to others.
2. 2.
Cover your mouth and nose with a tissue when you cough or sneeze, or you can cough or sneeze into your sleeve, but avoid covering with your hands directly.
3. 3.
Wash your hands with soap and running water thoroughly for at least 15 seconds.
● Before eating and after using the toilet
● After returning home
● After touching trash or garbage
● After contacting with animals or handling animal wastes
4. Strengthen your immune system and exercise regularly
● Exercise regularly is one of the most important ways to help you stay away from catching any infections.
● Make sure that shared spaces have good air flow and avoid going to crowded places such as hospitals, railway stations and airports. Wear a mask if transport or movement is necessary.
● Seek prompt medical attention 4..
● Avoid close contact with people who have flu or cold-like symptoms.
●5.. Avoid contact with wild animals or farmed livestock without any protection.
A.If your hands are not visibly dirty
B.Eat thoroughly cooked meat and eggs
C.Wash your hands frequently and properly
D.Protect yourself and others from getting sick
E.if you have symptoms of fever and respiratory infection
F.Cover your coughs and sneeze with tissue
G.Make sure to wear it properly by tightening up the nose clip and pulling the bottom of it over your chin.
Rivers are the veins of the Earth, transporting the water and nutrients (营养物) needed to support the planet’s ecosystems, including human life. While many nutrients are essential to the survival of life, there is one element transported by water in rivers that holds the key to life and to the future of our planet — carbon.
Carbon is everywhere and understanding the way it moves and is either released or stored by the Earth system is a complex science in itself. Carbon starts its journey downstream when natural acid rain, which contains carbon dioxide from the atmosphere, melts minerals in rocks. This helps transform carbon dioxide to bicarbonate (碳酸氢盐) in the water that then flows in our rivers. This is a very long process, which is one of the main ways carbon dioxide is removed from the atmosphere. Carbon is transported by rivers to oceans and once that carbon reaches the ocean, it is stored naturally in deep sea sediments (沉淀物) for millions of years.
As carbon travels down a river, different processes may impact whether it continues to flow downstream or whether it is released into the atmosphere. For example, human engineering, like extensive dam construction, will result in dramatic changes to how water and sediments travel down the river. Some carbon that fails to reach the sea may return to the atmosphere in some way, which causes more warming.
Earth’s climate is closely related to the carbon cycle. We all know about the essential role of plants in consuming carbon dioxide, but do we know enough about rivers? Changing the chemistry and the course of rivers may have significant impacts on how they transport carbon. Remember: wherever we live, we all live downstream.
1.Where is the carbon in rivers originally from?
A.The atmosphere. B.The rocks.
C.The acid rain. D.The upstream areas.
2.Why is human engineering mentioned in Paragraph 3?
A.To show how important to life carbon is.
B.To explain how necessary it is to build dams.
C.To show how a natural process is interrupted.
D.To explain how humans fight global warming.
3.What does the author want to convey in the last paragraph?
A.We’d better move upstream to live.
B.We should protect plants along rivers.
C.We’d better seek more help from plants.
D.We should be cautious about river management.
4.What is the best title for the text?
A.What Humans Do with Rivers
B.How Rivers’ Transporting Carbon Counts
C.What the Carbon Cycle Means to Us
D.How Living Downstream Affects the Earth
