Degrees of Comparison of Adjectives and Adverbs

(not) as thick as                          not so clever as              as soon as possible

later than usually much (far) colder much many books

much more snow the morethe bettermost of the time

the biggest of all

Attention: Upper, Lower, inner, outer

20. Form degrees of comparison from the following adjectives:

 

Massive – Massiving, hard – harder, thick – thicker, thin – thiner, narrow – narrowing, complete – completing, big – bigger, large –  larger, great – greater, common – commoning, elastic – more elasting, muscular – more muscularing, close – closer, light – lighter, small – smaller, many, much – more,little – leas, good – better, bad – woorse, red – more red, warm, beautiful, cold, long, comfortable

 

21. Use the necessary degree of comparison:

 

1. The walls of the veins are not so (thick, thicker, the thickest) as those of arteries. 2. Liver is (hard-working, the hardest-working, less hard-working) organ than the heart. 3. Circulatory system has a (complicate, more complicate, the most complicate) network of (more different, different, the most different) types of vessels. 4 (Most, more, many) of veins carry deoxygenated blood to the heart but not all of them. 5. The (strongest, stronger, strong) a blood pressure is the (thick, thicker, the thickest) walls the vessels have. 6. The lumen of artery is much (the widest, wider, wide) than that of capillary.7. Capillaries are subjected to blood pressure (the least, less, little) of all.

 

22. Translate into Russian:

 

Much more thicker than walls of the ventricle;a massive and thick-walled artery; aorta branches into smaller arteries; across the broadest point; the smallest vessels; flow quickly and efficiently; thicker, more elastic, and more muscular walls;the body’s hardest-working organ;the largest arteries of the body;arterioles are narrower arteries that branch off from the ends of arteries;much lower blood pressures; due to their greater number; arteriole walls are much thinner than those of arteries;capillaries are the smallest and thinnest of the blood vessels in the body and also the most common; walls of veins are much thinner; less elastic, and less muscular than the walls of arteries; push blood through valves closer to the heart, deposit it into larger veins, veins have thinner walls, most of the force of the heart’s contractions

Гораздо толще стенок желудочка;массивная и толстостенная артерия; аорта разветвляется на более мелкие артерии; пересекает самую широкую точку; мельчайшие сосуды; течет быстро и эффективно; толстые, более эластичные и более мускулистые стенки;самый трудолюбивый орган тела;самые крупные артерии тела;артериолы-более узкие артерии, которые отходят от концов артерий;гораздо более низкое кровяное давление; из-за их большего количества; стенки артериол намного тоньше, чем стенки артерий;капилляры-самые маленькие и тонкие из кровеносных сосудов в теле, а также Самые распространенные; стенки вен гораздо тоньше; менее эластичны и менее мускулисты, чем стенки артерий; проталкивают кровь через клапаны ближе к сердцу, откладывают ее в более крупные вены, вены имеют более тонкие стенки, большую часть силы сокращений сердца
