2、h going and coming, and the voyage has been performed wholly by the power of the steam engine. I overtook many boats beating against the wind and parted with them as if they had been at anchor.

Passage 3Blood vessels running all through the lungs carry blood to each air sac, or alveolus, and then back again to the heart. Only the thin wall of the air sac and the thin wall of a capillary are between

16、the air and the blood. So oxygen easily diffuses, from the air sacs through the walls into the blood, while carbon dioxide easily diffuses from the blood through the walls into the air sacs.When blood is sent to the lungs by the heart, it has come back from the cells in the rest of the body. So the

17、blood that goes into the wall of an air sac contains much dissolved carbon dioxide but very little oxygen. At the same time, the air that goes into the air sac contains much oxygen but very little carbon dioxide. You have learned that dissolved materials always diffuse from where there is more of th

18、em to where there is less. Oxygen from the air dissolves in the moisture on the lining of the air sac and diffuses through the lining into the blood. Meanwhile, carbon dioxide diffuses from the blood into the air sac. The blood then flows from the lungs back to the heart, which sends it out to all o

19、ther parts of the body.Soon after the air goes into an air sac, it gives up some of its oxygen and takes in some carbon dioxide from the blood. To keep diffusion going as it should, this carbon dioxide must be gotten rid of. Breathing, which is caused by movements of the chest, forces the used air o

20、ut of the air sacs in your lungs and brings in fresh air. The breathing muscles are controlled automatically so that you breathe at the proper rate to keep your air sacs supplied with fresh air. Ordinarily, you breathe about twenty-two times a minute. Of course, you breathe faster when you are exerc

21、ising and slower when you are resting. Fresh air is brought into your lungs when you breathe in, or inhale, while used air is forced out of your lungs when you breathe out, or exhale.Some people think that all the oxygen is taken out of the air in the lungs and that what we breathe out is pure carbo

22、n dioxide. But these ideas are not correct. Air is a mixture of gases that is mostly nitrogen. This gas is not used in the body. So the amount of nitrogen does not change as air is breathed in and out. But while air is in the lungs, it is changed in three ways: (1) About one-fifth of the oxygen in t

23、he air goes into the blood. (2) An almost equal amount of carbon dioxide comes out of the blood into the air. (3) Moisture from the linings of the air passages and air sacs evaporates until the air is almost saturated.Questions for Passage 33.2 (a) In the respiratory process, the following action ta

24、kes place: GENERALIZATION A. diffusion of blood through capillary walls into air sacs. B. diffusion of carbon dioxide through capillary and air sac walls into the blood. C. diffusion of oxygen through the air sac and capillary walls into the blood. D. exchange of alveoli and oxygen within air sacs.

25、E. none of the above. 3.2 (b) While air is in the lungs, it changes In the following way:GENERALIZATION A. nitrogen is absorbed from the air. B. about one-fifth of the carbon dioxide and about one-half of the oxygen in the air goes into the blood. C. the moisture in the air is almost completely evap

26、orated. D. about one-fifth of the oxygen in the air goes into the blood and an equivalent amount of carbon dioxide enters the air from the blood. E. none of the above changes are correct.3.3 The number of times per minute that you breathe isDETAIL A. independent of your rate of exercise. B. fixed at

27、 twenty-two times per minute. C. influenced by your age and sex. D. controlled automatically by an unspecified body mechanism. E. dependent upon the amount of fresh air available to you at any given time.3.5 The process by which carbon dioxide and oxygen are transferred does not depend on CONCLUSION

28、 A. the presence of nitrogen in the blood. B. the muscles of the thoracic cavity. C. the flow of blood, D. the moisture in the air sac linings. E. the process of diffusion.3.7 The authors style in this passage can best be described asTONE A. informal and matter of fact. B. pedantic. C. impersonal. D

29、. matter of fact. E. personal.Passage 4Another thing to remember in connection with concrete is that you are not allowed very much leeway for errors in either measurements or location. Once you have a solid mass of concrete set in place, it is going to stay there. You have a difficult job ahead of y

30、ou if you try to remedy a mistake. Make very sure, before you fill the form, that everything is where and how you want it.There are numerous rules regarding the proper mixing, handling, and finishing of concrete, but the essential one concerns the amount of water to use. The less water in the mix, t

31、he less the finished job will shrink. The less water used, the harder and more enduring the job after it has set.The amateur concrete worker is plagued with two desires. One is to use enough water to have the concrete nice and soft and easy to push around. You have been warned against that. The seco

32、nd is to take off the wooden forms too early, to see what the job looks like. That is really fatal. If the forms are stripped off too soon, while the concrete is still green, two things are likely to happen - you are almost sure to break off corners or edges, and you are likely to cause a major crack or defect in the body of the work. An excellent rule is to wait until you are sure the concrete is properly hardened, and then wait another day before
