It has long been known that when exposed to sunlight under suitable conditions of temperature and moisture(湿度), the green parts of plants absorb carbon dioxide()from the atmosphere(空气)and release oxygen to it in return. These exchanges are just the opposite of those which take place in human and animal’s respiration(呼吸). The course in which plants take in carbon dioxide()and release oxygen(O)is called photosynthesis.
In photosynthesis(光合作用), carbohydrates(碳水化合物)are formed from carbon dioxide()and water()by the green matter(chlorophyll)of plant cells in the presence of sunlight. Oxygen is the product of this chemical reaction. For each molecule(分子)of carbon dioxide()used, one molecule(分子) of oxygen is produced. Therefore, such a chemical equation(反应式)for photosynthesis can be summed up as the following:
58. In photosynthesis, the combination of carbon dioxide and water to form sugar results in the production of __________.
A. chlorophyll B. carbon C. hydrogen D. oxygen
59. In photosynthesis, water _________.
A. must be present
B. is produced in carbohydrates
C. is stored as chemical energy
D. is the only substance that keeps plants alive

A. almost the same asB. rather similar to
C. the opposite ofD. rather different from
61. In the course of photosynthesis, __________ is the prerequisite(先决条件).
A. water B. chlorophyll C. temperature and moisture D. sunlight
62. The title that can best express the main idea of this passage is __________.
A. The Function(作用)of Chlorophyll
B. The Course of Photosynthesis
C. A Well-known Chemical Equation
D. The Production of Sugar

During the American War of Independence, women played an active part in fighting in three ways. First, women formed a special branch of the Continental Army, spoken of as “Women of the Army”, some women worked as nurses in the field hospitals, tending wounded soldiers; some worked as cooks in the army troops; a good many women acted as water carriers, when necessary, all the above-mentioned women who had had many chances to observe how the men fired guns, could take the place of the wounded men.
