Avalanchesare____1____ the biggest dangers in the mountains for both life and property.All avalanches are caused by an over-burden of material, typically snowpack, that is too massive and unstable for the slope____2____ supports it. Determining the critical load, the amount of over-burden which is____3____ cause an avalanche, ____4____ acomplex task involving the evaluation of a number of factors.Terrain slopes flatter than25degrees or steeperthan60degrees typically have a low ____5____ of avalanche. Snow does not____6____ significantly on steep slopes; also, snow does not ____7____ easily on flat slopes. Human-triggered avalanches have the greatest incidence when the snow’s angle of rest1 is____8____ 35 and45 degrees; the critical angle, the angle at which the human incidence of avalanches is greatest, is38degrees. The rule of thumb2 is：A slope that is____9____ enough to hold snow but steep enough to ski has the potential to generate an avalanche, regardless of the angle. Additionally3, avalanche risk increases with____10____;that is, the more a slope is disturbed by skiers, die more lijkely it is that an avalanche will occur.Due to the complexity of the subject, winter travelling in the backcountry4 is never 100% safe. Good avalanche safety is a continuous____11____,, including route selection andexamination of the snowpack, weather____12____ and human factors. Several well-known good habits can also____13____ the risk. If local authorities issue avalanche risk reports, they should be considered and all warnings should be paid____14____ to. Never follow in the tracks of others without your own evaluations; snow conditions are almost certain to have changed since they were made. Observe the terrain and note obvious avalanche paths where plants are____15____ or damaged. Avoid traveling below others who might trigger an avalanche.词汇：avalanche n.雪崩snowpack n.积雪场terrain n.地形，地势steep adj.险峻的，陆峭的trigger v.引起，激发incidence n.发生(率)ski v.滑雪complexity n.复杂性注释：1.angle of rest：这里指积雪保持静止的角度。

2019年理工类职称英语考试完形填空训练试题完形填空We are so used to our life on the surface of the earth that it can be quite an effort for our mind to break free of all the ideas that we take for granted.

But Opportunity has continued to collect and analyze Martian soil and rocks.During its mission, Opportunity has captured, and sent backto Earth, some 187,000 panoramic and microscopic images of Mars with its cameras. ____4____MARATHON ROVERThe rover doesn’t seem to be ready to stop just yet. If Opportunity can continue on, it will reach another major investigation site when its odometer hits 26.2 miles.____5____Researchers believe that clay minerals exposed near Marathon Valley could hold clues to Mars’s ancient environment 1 . Opportunity’s continuing travels will also help researchers as they plan for an eventual human mission to the Red Planet.词汇：Mars rover n. 火星车panoramic adj. 全景的odometer n. 里程计rack up v. 积累microscopic adj. 微观的注释：1.could hold clues to Mars’s ancient environment：含有与火星早期环境相关的线索。

2019年职称英语(理工类)补全短文文章及译文2 How Deafness Makes It Easier to HearMost people think of Beethoven's hearing loss as an obstacle to composing music. However, he produced his most powerful works in the last decade of his life when he was completely deaf.This is one of the most glorious cases of the triumph of will over adversity, but his biographer, Maynard Solomon, takes a different view. 1 . In his deaf world Beethoven could experiment, free from the sounds of the outside world, free to create new forms and harmonies. Hearing loss does not seem to affect the musical ability of musicians who become deaf. They continue to"hear" music with as much, or greater, accuracy than if they were actually hearing it being played.2 . He described a fascinating phenomenon that happenedwithin three months：" my former musical experiences began to play back to me. I couldn't differentiate between what I heard and real hearing. 2 After many years, it is still rewarding to listen to these playbacks, to ' hear' music which is new to me and to find many quiet accompaniments for all of my moods. "How is it that the world we see, touch, hear, and smellis both"out there" and at the same time within us? There is no better example of this connection between external stimulus and internal perception than the cochlear implant.3 . However, it might be possible to use the brain's remarkable power to make sense of the electrical signals the implant produces.When Michael Edgar first" switched on" his cochlear implant,the sound's he heard were not at all clear. Gradually, with much hard work, he began to identify everyday sounds.For example," The insistent ringing of the telephone became clear almost at once. "The primary purpose of the implant is to allow communication with others. When people spoke to Eagar, he heard their voices "coming through like a long-distance telephone call on a poor connection. " But when it came tohis beloved music, the implant was of no help. 4 . He said,"I play the piano as I used to and hear it in my head at the same time. The movement of my fingers and the feel of thekeys give added ' clarity' to hearing in my head. ''Cochlear implants allow the deaf to hear again in a way that is not perfect, but which can change their lives. 5 . Even the most amazing cochlear implants would have been useless to Beethoven as he composed his Ninth Symphony at the end of his life。

2019年职称英语理工类C级概括大意题(5)1 Health education is the part of health care that is concerned with promoting healthy behavior. A person'sbehavior may be the main cause of a health problem, but itcan also be the main solution. This is true for the teenager who smokes, the mother with the poorly nourished （营养）child, and the butcher （屠夫，卖肉的人） who gets a cut onhis finger. By changing their behavior these individuals can solve and prevent many of their own problems. 2 Health education does not replace other health services, but it is needed to promote the proper use of these services. One example of this is immunization （免疫）： scientistshave made many vaccines （疫苗） to prevent diseases, butthis achievement is of no value unless people go to receivethe immunization.3 Health education encourages behavior that promotes health, prevents illness, cures disease, and contributes to recovery. The needs and interests of individuals, families, groups, organizations, and communities are at the heart of health education programs. Thus there are many opportunities for practicing health education.4 Health education is not the same thing as health information. Correct information is certainly a basic part of health education, but health education must also address the other factors that affect health behavior such asavailability （可获性） of resources, effectiveness of community leadership, social support from family members, and levels of self-help skills. Health education therefore uses avariety of methods to help people understand their own situations and choose actions that will improve their health. Health education is incomplete unless it encourages involvement and choice by the people themselves.5 Also, in health education we do not blame people if they do not behave in a healthy way. Often unhealthy behavior is not the fault of the individual. In health education we must work with families, communities, and even regional and national authorities to make sure that resources and support are available to enable each individual to lead a healthy life.。
