You may think that people are capable of living in a wide range of environments, from the hot deserts of Africa and the Middle East to the freezing cold of Siberia or Northern Canada. Being an intelligent species, we worked out how to use fire to keep us warm in cold conditions and, considerably later, air conditioning to keep us cool in hot climates. But there is a wide variety of organisms capable of living in environments in which no human could survive-the extremophiles. Take, for example, Spinoloricus cinzia, a tiny creature, about a millimeter long and looking a little like a jellyfish. This recently discovered animal is particularly interesting, as it appears to be capable of living without oxygen and is thus a multi-cellular anaerobe. The cells of most organisms contain mitochondria, which use oxygen to generate energy, whereas the cells of Spinoloricus cinzia do not contain mitochondria. Most anaerobes so far discovered are microbes and use a form of fermentation to gain energy. Some anaerobes will actually die in the presence of oxygen. 97. What is the main purpose of the passage? 1) To introduce a special type of creature 2) To show the role of fire in human survival 3) To prove the unimportance of oxygen for life 4) To describe newly discovered unfriendly environments 98. Which of the following statements about anaerobic organisms is supported by the passage? 1) They are all discovered and known to us. 2) They can live in a wide range of environments. 3) They have cells all of which have no mitochondria. 4) They are capable of surviving in environments empty of oxygen. 99.What does the word “which" in paragraph 2 refer to? 1) organisms 2) cells of most organisms 3) mitochondria 4) multi-cellular anacrobe 100. Which of the following reasoning techniques is NOT used in the passage? 1) Describing cause-and-effect relationships 2) Describing the steps in a process 3) Referring to differences 4) Use of examples (4 نمره)
