When we are born,we are given names that stay with us for our whole lives. Some names include good wishes and hopes from parents, while others may be unique and easy to remember.
1.
According to International Committee on Taxonomy of Viruses, an organization responsible for naming new viruses,the task of naming a virus is no less important than naming a person.
When a disease breaks out, people focus on the public health response 2. But that may lead to many problems. The most obvious one is that different media organizations may use different names for the same virus in their reports. We are now in the internet era. 3. This means different names can take hold quickly and be hard to take back, which may confuse those who know little about the virus.
4. Over the past decade, some improper names have caused problems. In 2009, the “swine flu” was widely used before the official name, HINI virus, was announced. This led Egypt to kill all of its pigs. In 2015, MERS (Middle East Respiratory Syndrome)caused a backlash (强烈抵制)against the nations and people of this region. So in 2015, the World Health Organization (WHO) announced that the names of viruses should avoid being named after geographic locations, people, species or classes of animals and foods.
5. The new coronavirus we are suffering from was named “COV-ID-19” on Feb 11. In this name, “CO” means “corona”, “VI” stands for “virus” and “D” means “disease”. Next time you read about a virus you don't know, you may get some clues about it from its name.
A.But naming a virus is never easy.
B.The WHO followed these principles this time .
C.News can spread to every household in seconds.
D.They often don’t know how to protect themselves.
E.The official naming of a new virus is often delayed.
F.Do you have a name which is easy to remember?
G.But do you know how the new coronavirus got its name?
Today we know Antarctica as an extreme environment containing ice and snow. But new research provides evidence that the area was very different in the past.
The evidence was found inside a piece of earth sediment(沉积物) collected by researchers from a depth of about 30 meters below the ocean floor off the coast of Antarctica. In the sediment, they found forest soil estimated to be about 90 million years old. This would have been in the Cretaceous Period, when dinosaurs were the main land animals.
Johann Klages is a geologist, working in the Institute's Helmholtz Center for Polar and Marine Research in Germany. He said an examination showed that the material formed on land, not in the ocean.
The researchers estimate that the area – about 900 kilometers from the South Pole – had average yearly temperatures of about 12 to 13 degrees Celsius. During the warmest summer months, average temperatures likely reached between 20 to 25 degrees Celsius. The average yearly temperature in that area is about 40 degrees below zero Celsius.
The examination results showed “a dense network of roots that spread through the entire soil layer,” the Helmholtz Center said in a statement.
The dark brownish-gray soil included fine dirt particles and hard clay, as well as substances linked to at least 65 different kinds of plants, the study found. Klages put that the plants included trees, ferns and flowering plants and while no animal remains were found, there were likely dinosaurs, flying reptiles and many insects in the environment.
The researchers said that the rainforest environment in Antarctica was especially surprising because each year, the area experiences a four-month polar night when there is no sunlight to fuel plant life.

A.Science. B.Entertainment. C.Society. D.Fiction.
4.What can be a suitable title for the text?
A.Antarctica, Once a Warm Rainforest

There are only a few truly pleasant smells to wake up to in the morning. It might be the aroma of freshly baked bread, or the scent of your partner’s freshly brushed teeth - but for me, it’s the smell of freshly cooked coffee. Just a sniff of it makes me jump out of bed and rush to the kitchen for a gulp(大口) of the hot black liquid.
I also know the experience when I walk into a cafe for my double espresso(浓缩咖啡) or flat white, my mouth begins to water in advance. Although it’s really the caffeine hit I’m after, it’s the smell that makes me feel good.
However, this feeling sometimes turns to disappointment when I actually start drinking my hot coffee - the taste just doesn’t match the smell. This is particularly the case when I order a coffee to go in a tall paper cup and sip the liquid through a hole in the lid. Yes, it’s convenient, but is it really the right way to appreciate it?
Tim Hayward, a food writer and coffee shop owner，describes this process as “strange”. He says, “You walk into the coffee shop, you get the smell, but when you actually take the drink out, you are drinking it from something that is designed to deliver the hot liquid directly past your tongue, but stop any smell coming up to your nose.”
As well as removing the smell, takeaway coffee cups create a lot of waste and a vast majority of them still don’t get recycled. In 2011, it was estimated that 2.5 billion coffee cups were thrown away each year in the UK, and that figure is likely to be higher now. So maybe now is the time to really wake up and smell the coffee by drinking from a cup or mug in a cafe, chatting with friends and saving the planet!

Do you prefer reading an e-book or a physical version? It might be a surprise, but for most people, old school print on paper still wins.
Publishers of books in all formats made almost $26 billion in revenue (收益) last year in the U.S., with print making up $22.6 billion and e-books taking $2.04 billion, according to the Association of American Publishers’ annual report 2018. Those figures include trade and educational books, as well as fiction.
While digital media has developed quickly, people still love to own physical books, according to Meryl Halls, managing director of the Booksellers’ Association in the U.K. “I think the e-book bubble has burst somewhat. Sales are flattening off. The physical objects are attractive.” she said.
People love to display their books, Hall added. “The book lover loves to have a record of what they have read. It’s about signaling to the rest of the world and about decorating your home, because people want to use it to indicate something about themselves.” And for Halls, there is also a desire to escape the screen. Part of the reason is that it’s harder to have an emotional relationship with what you’re reading if it’s on an e-reader.
As for the future of books, all formats will continue to be in demand, says Jacks Thomas, director of the London Book Fair. “People always need knowledge and people always need stories, so from that point of view, the book industry, in whatever format, has a strong future,” she says.

Superb Performance From Affordable Digital Hearing Aid
Chicago Dr. Cherukuri has invented a medical-grade, ALL-DIGITAL，affordable hearing aid.
He knew that untreated hearing loss could lead to depression, social isolation, anxiety, and symptoms consistent with dementia and Alzheimer’s disease. In his practice he knew that many of his patients would benefit from new digital hearing aids but many couldn’t afford the expense, which is not generally covered by Medicare and most private health insurance policies.
Same Technology as $ 3,500 Hearing Aids
He evaluated all the high-priced digital hearing aids on the market and then created his own affordable version-called MD Hearing Aid AIR for its virtually invisible, light weight appearance. This doctor-designed digital hearing aid delivers clear sound all day long and the soft flexible ear domes are so comfortable that you won’t realize you are wearing them.
This new digital hearing aid is packed with the features of its $3,500 competitors at a small part of the cost. Now most people with hearing loss are able to enjoy crystal clear, natural sound-in a crowd, on the phone, in the wind --without “whistling” and annoying background noise.
