Welcome to Mr Aslanov’s cefr lessons

 
Q4. 
Birds used for the production of Foie Gras are trapped in tiny cages, where they hardly have any place 
to move or flap their wings. Mechanized feeders come at regular intervals to feed them and metal pipes are 
forced down their gullets several times a day. The overfed birds have difficulty breathing and acquire a 
range of diseases. Once these birds have reached a point of neardeath, they are slaughtered, and their livers 
end up in restaurants! 
 
Q5. 
Animals adapt over time to their environments, some so much so that they begin to look like their 
surroundings — a helpful evolutionary advantage in the face of potential predators (or while stalking prey). 
There are octopi that blend in perfectly with sandy ocean floors, insects that look just like leaves and fish 
that resemble oceanic plants. There is even an octopus that can mimic nearly twenty other oceanic species 
to scare off.
Q6. 
Humans work together all the time to build incredible structures we could never have dreamed up, let 
alone construct, on our own — but some animal architecture is arguably even more impressive. There is a 
spider web built by a variety of species working together that spans much of a public park, an ant colony 
that extends for thousands of miles and birds nests built by entire flocks living together under one thatched 
roof. 
Q7. 
Raining animals… it sounds ridiculous, right? Nonetheless, it happens — although rarely. Fish, frogs 
and birds are the most common forms of animal rain. Sometimes the creatures land relatively unscathed 
but in other cases they are frozen or shredded to pieces. Theories vary in their details but generally it is 
assumed that certain kinds of strong winds lift up the animals with a volume of water (fish and frogs from 
ponds, for example) or sweep them out of the sky in the case of birds and then deposit them, often 
right before a major storm.
