Simply being bilingual doesn’t qualify someone to interpret. Interpreting is not only a mechanical process of converting one sentence in language A into the same sentence in languageb. Rather, its a complex art in which thoughts and idioms that have no obvious counterparts from tongue to tongue _ or words that have several meanings must be quickly transformed in such a way that the message is clearly and accurately expressed to the listener.

 At one international conference, an American speaker said, “You cant make a silk purse out of a sows ear”, which meant nothing to the Spanish audience. The interpretation was, “A monkey in a silk dress is still a monkey” _ an idiom the Spanish understood and that expressed the same idea.

 There are 2 kinds of interpreters, simultaneous and consecutive. The former, sitting in a separated booth, usually at a large multilingual conference, speaks to listeners wearing headphones, interpreting what a foreign language speaker says _ actually a sentence behind. Consecutive interpreters are the ones most international negotiations use. They are employed for smaller meetings without sound booths and headphones. Consecutive interpretation also requires two-person teams. A foreign speaker says his piece while the interpreter, using a special shorthand, takes notes and during a pause, tells the client what was said.

Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the following questions

Fish that live on the sea bottom benefit by being flat and hugging the contours. There are two very different types of flatfish and they have evolved in very separate ways. The skates and rays, relatives of the sharks have become flat in what might be called the obvious way. Their bodies have grown out sideways to form great “wings” They look as though they have been flattened but have remained symmetrical and “the right way up”. Conversely fish such as plaice, sole, and halibut have become flat in a different way. There are bony fish which have a marked tendency to be flattened in a vertical direction; they are much “taller” than they are wide. They use their whole vertically flattened bodies as swimming surfaces, which undulate through the water as they move. Therefore when * their ancestors migrated to the seabed, they lay on one side than on their bellies. However, this raises the problem that one eye was always looking down into the sand and was effectively useless - In evolution this problem was solved by the lower eye “moving” around the other side. We see this process of moving around enacted in the development of every young bony flatfish. It starts life swimming near the surface, and is symmetrical and vertically flattened, but then the skull starts to grow in a strange asymmetrical twisted fashion, so that one eye for instance the left, moves over the top of the head upwards, an old Picasso - like vision. Incidentally, some species of 20 flatfish settle on the right side, others on the left, and others on either side.
