ich wäre euch sehr dankbar, wenn ihr einen Blick auf nachstehenden Text (fiktive 'Präsentation' für Englischkurs) werfen könntet. Nicht erschrecken, der Text ist zwar sehr lang, aber es geht mir hauptsächlich um die in Großbuchstaben (fett ging leider nicht) hervorgehobenen Stellen. Um den Kontext nicht außeinanderzureißen, habe ich darauf verzichtet, diese Satzteile einzeln anzufragen. Any comment will be appreciated.
Generally, there are two types of snakes: those WHO (THAT?) strangle their victims to death and those who (S. O.) use their venom to kill them. As we only have 5 minutes time until the next group comes in, I will limit my talk to those snakes that are potentially deadly to human beings; BE IT (correct?) because of their enormous size or due to their extremely strong venom.
Let's start with constrictor snakes: there are two species THAT STRUGGLE FOR BEING ENTITLED THE BIGGEST SNAKE (correct?) in the world: The Reticulated Python and the famous Anaconda. With up to 10 m (LENGTH?), the Reticulated Python is the longest snake, but with still 9 m and an incredible weight of more than 200 kg, the Anaconda definitely is the heaviest. However, both of them wouldn't have the slightest problem to kill and eat one of us. By the way, after this meal the snake wouldn't have to eat for half a year or even longer.
Legends tell us about big Pythons and Anacondas with more than 14 m lengths. Considering the fact, that reptiles keep steadily growing all their lives (what can be more than 20 years), it is absolutely possible that such big animals had existed before mankind started destroying their habitats and killing them for fear, for their skin or just for fun.
A constrictor snake winds around its prey and each time, the victim breathes out, the snake pulls harder until the victim is not longer able to breathe in and finally suffocates. As soon as the meal HAS DIED (IS DEAD?), the snake swallows it in one peace, head first. To do this, the snake dislocates its jaws, and by contracting its enormous muscles MOVES (?) the food down to the stomach.
Poisonous snakes eat in the same way, but they don't need to choke their victims. Instead of that they rely on their venom that can be either neurotoxic (what means it affects the nervous system and so paralyzes respiration) or it can be haemotoxic (what means that it affects the blood. It MAKES (?) tissue die off, MAKES (S. O) blood agglutinate and so not only can cause the loss of an extremity but also can lead to apoplexy or heart attack).
Every year, about 5 million people GET (ARE?) bitten by venomous snakes. 125.000 of them die. The biggest venomous snake is the King Cobra. It can REACH (?) more than 5 m length and has a very strong venom that can kill a human being within a few minutes. The quantity of venom injected in one single bite would be enough to kill an elephant or 10 humans or about 100.000 mice. The King Cobra's main food is other snakes, what is very unusual as most snakes eat mammals, birds or animals like frogs and lizards.
One of the smallest venomous snakes is the Australian Death Adder. Even though it is only 50 to 90 cm long, it is the third deadliest snake in the world and can kill a rat within less than 10 seconds.
The deadliest snake is the Fierce Snake that also lives in Australia. It possesses both, neurotoxic AND haemotoxic venom, and one bite can kill 150 humans or 250.000 mice.
The quickest snake is the African Boomslang with a maximum speed of 50 kilometers per hour. The quickest bite has the Puff Adder. Even though this snake usually is very lazy and doesn't move much, it can bite WITH A SPEED OF 6 METERS PER SECOND (?) when somebody accidentally steps on it. Most snakebites in Africa ARE CAUSED BY this animal. (Gibt es hier vielleicht einen hübscheren Ausdruck für "gehen auf das Konto dieses Tiers"?)
Another interesting species is the Spitting Cobra. Like any other cobra it has a strong venom but tries to avoid biting whenever possible. When feeling endangered, the cobra spits HER (ITS) venom precisely into it's enemy's eyes. As this hurts very much and even may cause blindness, the snake has enough time to disappear.
There would be so much more to tell about this fascinating animals, but I have to come to the end, the next group is waiting already.
We have learned that there are several snakes that can be dangerous for us, but I can assure you that they are no bloodthirsty monsters but usually only attack us when they feel endangered. And this brings me to my conclusion: don't harm the snake and the snake won't harm you!
I hope you enjoyed this little trip to the world of snakes and I thank you very much for your attention.
