9、ealed advantages of a kind not possessed by any of their competitors. In the search for the pickings of the forest, the ape-men had 5efficient stereoscopic vision and a sense of colour that the animals of the grasslands did not possess. The ability to see clearly at close range permitted the ape-men

10、 to study practical problems in a way that lay far beyond the reach of the original inhabitants of the grassland. Good long-distance sight was 6 another matter. Lack of long-distance vision had not been a problem for forest-dwelling apes and monkeys because the higher the viewpoint, the greater the

11、7 of sightso what they had had to do was climb a tree. Out in the open, however, this simple solution was not available. Climbing a hill would have helped, but in many places the ground was 8. The ape-men adopted the only possible solution. They reared up as high as possible on their hind limbs and

12、began to walk upright. This vital change of physical position brought about considerable 9. It was extremely unstable and it meant that the already slow ape-men became slower still. However, they persevered and their bone structure gradually became adapted to the new, unstable position that 10 them

16、theory held that the two phases are 5 different kinds of molecules. The theories now prevailing take a quite different approach by emphasizing what liquids and gases have in common.

He should be able to type fairly quickly and accurately and, if he is working mainly for publication, should have more than a nodding 5 with printing techniques and proof-reading. If he is working basically as an information translator, let us say, for an industrial firm,

23、 he should have the flexibility of mind to enable him to 6 rapidly from one source language to another, as well as from one subject-matter to another, since this ability is frequently required of him in such work. Bearing in mind the nature of the translators work, i.e. the processing of the written

24、 word, it is, strictly speaking, 7 that he should be able to speak the languages he is dealing with. If he does speak them, it is a(n) 8 rather than a hindrance, but this skill is in many ways a luxury that he can do away with. It is, however, desirable that he should have an approximate idea about

25、the pronunciation of his source languages even if this is restricted to 9 how proper names and place names are pronounced. The same applies to an ability to write his source languages.
