<u>Dear Ned,
</u>
<u>How are you? Thanks for your letter.</u>
In it you asked me about my yesterday's day and I would like to tell you.
Yesterday I was in the country with my family. It was a very nice day.First, I and my sister helped our granny. We planted and hand feed lambs. Then I and my mom started to cook dinner. It was funnily!
What about you? What animals have you seen in zoo? Did you like to see them?
<u>Well, I've got to go now! Write back soon!</u>
<u>Yours,</u>

1 Virology is often considered as a part of microbiology
2 Viruses can be classified according to the host cell they infect: animal viruses, plant viruses, fungal viruses,and bacteriophages (viruses infecting bacteria, which include the most complex viruses).
3 Another classification uses the geometrical shape of their capsid (often a helix or an icosahedron) or the virus's structure (e.g. presence or absence of a lipidenvelope).
4 A virus is a small infectious agent that can replicate only inside the living cells of organisms.
5 Viruses are found in almost every ecosystem on Earth.
6 Viruses cause a number of diseases in eukaryotes.
7 Viral infections in animals provoke an immune response that usually eliminates the infecting virus.
8 The evolution of viruses, which often occurs in concert with the evolution of their hosts, is studied in the field of viral evolution.
9 While viruses reproduce and evolve, they don't engage in metabolism and depend on a host cell for reproduction.
