    Endangered Species Day is a bittersweet event. While it's heartbreaking to think back on all the species we have already lost during our last few generations, and all we stand to lose in the next few.1..

Make a donation to a conservation organization. Every penny helps these local, national and interactional groups to do on-the-ground work in protecting habitats and species.2..

Visit your local natural history museum virtually. You'll learn a lot about your local wildlife including species that may be threatened with decline. Endangered species aren't just rhinos in Africa or leopards in Asia- they're also the insects, birds, mammals and even plants right in our own backyards, and many times there is the opportunity to protect them.

Join a wildlife conservation organization. There are many organizations to choose from including the National Wildlife Federation, National Audubon Society, Wildlife Conservation Network and more.3.. Your membership shows your ongoing support and also provides a way to stay in the loop about what's happening and how you can help.

4.. Today is the perfect day to send a few tweets, add a few Facebook updates, photos about endangered species conservation. You can be a source of information and awareness today and perhaps inspire even more people to get involved!

Stay informed! Make it a daily practice to check in on news about endangered species on a local, national or global level. You'll be able to see when and how you can help.

Many species are endangered now, but we can change that; we can end poaching, habitat destruction, pollution and so many other factors causing declines around the world,5..

A.Even if it's just $5, it helps

B.It is time to get involved and make a difference

C.So let's celebrate it with as many people as possible

D.It's also a chance to look at some ways we can get started

E.Volunteer to work in some wildlife conservation organizations

F.Take to social media with information about endangered species

G.You can join a larger organization or even one that focuses on specific species or habitats

    Fever, coughing, sore throat… most of us at one time or another have had these symptoms. What causes them?  In fact, many diseases are caused by viruses, including some deadly ones like AIDS, SARS and COVID-19, also known as the novel coronavirus pneumonia, outbreak in China.

What are viruses?  How can viruses cause so much trouble?  Viruses are very small particles (颗粒) which are about one millionth of an inch long. Unlike human cells or bacteria, viruses aren’t living organisms- they can't reproduce on their own. Instead, they invade the cells of living organisms to reproduce, spread and take over.

Virus can infect every living thing- from plants and animal down to the smallest bacteria. For this reason, they are always a potential danger to humans. 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. Once inside, they try to find a host cell to infect. 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? Until now, no clear explanation for their origin exists. "Tracing the origins of viruses is difficult, "Ed Rybicki, a scientist at the university of Cape Town in South Africa, told Scientific American, "because viruses don' t leave fossils 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 dependent 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.

For the time being, these are only theories. The technology and evidence we have today cannot be used to test these theories and identify the most reasonable explanation. Continuing studies may provide us with clearer answers or future studies may find that the answer is even more mysterious than it now appears.

1.What can we learn about viruses from the text?

A.Viruses are really small living organisms.

B.Viruses have nothing to do with the common cold.

C.Viruses can't reproduce unless they find a host cell.

D.Viruses enter our bodies mainly through our mouths, noses and hair.

2.Why are viruses always a potential danger to humans?

A.TH most infect all the living things around us.

B.They prefer evolving with the cells in our body.

C.They can copy human's DNA and evolve successfully.

D.They can enter our body far more easily than other living things.

3.Which of the following might explain the origin of viruses?

A.They evolved from the DNA of animals.

B.They evolved along with their host cells.

C.They evolved from the fossils of large organisms.

D.They evolved from parasites to independent organisms.

4.What can we conclude from the last paragraph?

A.The author is confident about future virus research.

B.Viruses will become more like bacteria as they evolve.

C.Viruses live longer in human host cells than in animals.

D.It may take a long time to understand the origin of viruses.
