I ask myself a version of this question every day: "Have you ever really looked at…？”You can【49】______in the blank yourself. Every day I am blinded by【50】familiar______. I open our beehive, which is filled with honey, and the particularity of the honeybees, and even of their community, somehow escapes me, if only because I’ve been living with honeybees a good part of my life. I remember the phrase, "keep your eyes【51】______ (peel) , ”and maybe that’s what I need, a good peeling. Again and【52】______, I find myself trying to really look at what I' m seeing. It happened the other afternoon, high on a nearby mountain. A dragonfly had settled on the denuded tip of a pine bough. It clung, still as only a dragonfly can be. Then it flicked upward and caught a midge and settled on the bough again, adjusting【53】______(precise) to the wind. I see dragonflies【54】______ (quiver) in the insect clouds above my pasture, too. I am always aware, however , that there’s no such thing as really looking. What I want to see is invisible anyway: the prehistoric depth of time embodied in the form. of those dragonflies, the pressure of life itself, the web of【55】______(relate) that bind us all together. I find myself trying to【56】wit______the moment when the accident of life becomes a continued purpose. But this is a small farm, and, being human, 1 keep【57】______(come) up against the limits of what a human can see. This morning I found a spider resting—or perhaps hunting—on the leaf of a hydrangea, the axis of the spider’s abdomen perfectly aligned with the axis of the leaf. What I noticed was the symmetry of their placement, the way spider, and leaf resembled【58】_____other. What I wanted to determine was the spider’s intent. If I【59】c______, I would have asked it, "What are you doing？” Or, better yet, "Who are you？” But all I could do was look—and realizing that I was looking—make the【60】b______of what I’d seen. (16)

It is the same in history. Many things have been forgotten because we do not have any written account of them. Sometimes men did keep a record of the most important happenings in their country，but often it was destroyed by fire or in a war. Sometimes there was never any written record at all because the people of that time and place did not know how to write. For example, we know a good deal about the people who lived in China 4, 000 years ago, because they could write and leave written records for those who lived after them. But we know almost nothing about the people who lived even 200 years ago in central Africa because they had not learned to write. Sometimes, of course, even if the people cannot write, they may know something of the past. They have heard about it from older people and often songs and dances and stories have been made about the most important happenings, and these have been sung and acted and told for many generations, for most people are proud to tell what their fathers did in the past. This we may call ？remembered history ” . Some of it has now been written down. It is not so exact or so valuable to us as written history is, because words are much more easily changed when used again and again in speech than when copied in writing. But if there are no written records, such spoken stories are often very helpful. Which of the following is NOT suggested in the passage？ A.Written history is more reliable. B.Written records play an important role in learning about history. C.A written account of our daily activities helps to answer many questions. D.Where there are no written records, there is no history. Little is known about the central Africa 200 years ago because ______.A.there was nothing worth writing down at that time B.people there ignored the importance of keeping a record C.people there did not know how to write D.the written records were perhaps destroyed by a fire “ Remembered history” refers to ______.A.history based on a person’s imagination B.stories of important happenings passed down from mouth to mouth C.songs and dances about the most important events. D.both B and C “ Remembered history” is regarded as valuable only when ______.A.it is written down B.No written account is available C.it proves to be timely D.People are interested in it It is suggested that we could have learned more about our past if ancient people had ______.A.kept a written record of every past event B.burnt their written records in wars C.told exact stories of the most important happenings D.made more songs and dances 请帮忙给出每个问题的正确答案和分析，谢谢！

But if robots are to reach the next stage of laborsaving utility, they will have to operate with less human supervision and be able to make at least'a few decisions for themselves-goals that pose a real challenge.

One company gives every employee over 50 years old and who has been with them for 25 years, six months’ holiday on full pay.At the same time additional money can be made available by way of loans, to help them with projects they cannot otherwise offer.Most of the people who have already benefited from the scheme, have used the opportunity to travel to distant places like the Far East or South America and some have spent the money on their favorite hobbies, such as photography. The cost of providing these special holidays is fairly high but the directors feel it is well worthwhile because the employees are greatly refreshed by their long break from the pressures and routines of their jobs.The only problems are that the people concerned tend to have key jobs which can be difficult to fill on a temporary basis for a relatively long time.Besides, some employees find it difficult to re-adjust to the old routine after such a long time away.In addition, one or two people may not feel secure at leaving their job in someone else’s hands.On balance, however, there is no doubt that the idea is beneficial to industrial relations and a wonderful reward for long service. 31.Many workers would like to ___________. A.dream of long holidays at home B.spend a long time in unusual places C.buy a holiday away from home D.have a long holiday after many years 32.One company____________. A.gives money to employees over 25 years B.lends staff money to go on holidays C.allows long holidays to certain staff D.arranges long holidays for old employees 33.Most of the employees in the scheme ____________. A.take foreign trips B.develop their hobbies C.take up photography D.enjoy leisure activities 34.The directors feel that _____________. A.the staff get a lot of pleasures from the scheme B.older staff are very enthusiastic about holidays C.the scheme is more expensive than they expected D.the scheme is beneficial to staff relations 35.One of the problems is that ________________. A.it is difficult to fill a temporary job B.some employees are afraid of their colleagues C.it is difficult for some people to re-adjust to the old routine after a long break D.employees don’t feel secure when they are away
