Morse Code

Morse code turns every letter into a pattern of short and long signals: dots and dashes. The commonest letters were given the shortest patterns. E is one dot. T is one dash. Q, which is rare, is dash-dash-dot-dash. Because of that choice, an average message is much shorter than it would be otherwise. A message can be sent as sound, as light, or as taps on a pipe. That is why it survived so long: it needs almost no equipment. Timing carries the meaning. A dash is three times as long as a dot. The gap between letters is three dots long, and between words, seven. SOS was chosen because it is easy to recognise: three dots, three dashes, three dots.

  1. 1. What does "frequency" mean when talking about letters?
  2. 2. What does "survived" mean in this text?
  3. 3. What is the Morse pattern for SOS?
  4. 4. What is the Morse pattern for E?

The Salmon's Return

A salmon hatches in a river, swims to the sea, and comes back years later to the river it was born in. It finds its way home by smell. Every river carries its own mixture of soil, rock and plants, and a young salmon learns that smell before it leaves. The return journey is upstream. The fish leap waterfalls, sometimes several metres high, and they do not eat once they enter fresh water. Because it is not feeding, a salmon uses up its own body on the climb. By the time it reaches the gravel where it hatched, it is thin and worn. There it lays its eggs. Most Atlantic salmon die soon afterwards.

  1. 1. Does a salmon eat on the return journey?
  2. 2. What does "upstream" mean?
  3. 3. Where does a salmon hatch?
  4. 4. What is "gravel" here?
