There are plenty of symptoms that often show up as a result of eye strain from computer screens. It may fi

However, the extent to which computer screens damage eyesight is (4) unclear.Taking a ten to 15 minutes break every hour while working is a good way to help avoid this and rest your eyes, though your (5)

10、may not be as generous with your break periods, if possible, break up computer tasks and non-computer tasks throughout the day as much as possible.One of the major improvements in computer screens has also helped. Still, even an LCD screen, if it is not adjusted (6) or if it is too bright, can be ju

This is very important as many people tend to keep their LCD screens too bright, simply because they are not viewing them from a proper angle and may be trying to (7) for the “screen door“ effect.Fortunately, most of the eye damage, if it is to be called that, resulting from

14、Safari Top Five National Parks and Game ReservesAA South Africa safari (游猎) is the ideal wildlife trip to go on because the infrastructure and accommodation is superb in all the wildlife parks there and it is still highly affordable in comparison to other African countries. But given a choice some o

15、f the national parks and game reserves are better than others. Here is a top five list ranking them according to travel reports received at the African Safari Journals website, my safari experience of twenty plus years, industry forums, magazines and the general consensus of the experts.Kruger Natio

16、nal ParkBThe Kruger National Park has to rank as one of the best South Africa safari destinations, only slightly behind the Masai Mara and Serengeti when it comes to wildlife viewing because the vegetation in Kruger can be dense and sometimes impair the ability to see longer distances. But the varie

17、ty of animals, birds and ecosystems that you can experience here are unparalleled anywhere else in Africa and the accommodation, roads and facilities are top notch and all at a very affordable price.CIts not unusual to see lion, leopard, cheetah, a pack of wild dog, rhino, elephant, buffalo and a wh

18、ole host of antelope, crocodile and hippo in the course of a single trip including a variety of insects and reptiles. On the bird front you will be spoiled with a seemingly never-ending supply of eagles, hawks, water birds and a host of migratory and indigenous species to the tune of about 510 diffe

19、rent varieties.DYou can easily do a self drive safari here and still see a decent amount of wildlife especially if you stick to the central and southern portions of this massive park (larger than Ireland). The north has fewer animals due to dryer conditions but also fewer tourists which makes for a

20、more isolated and intimate wildlife experience. If variety is the spice of life then a South Africa safari in the Kruger National Park is a rich dish indeed.Sabi Sands Game ReserveESharing a fenceless border on the western side of the Kruger National Park is the Sabi Sands game (猎物) reserve which ha

21、s a number of world famous private concessions like Mala Mala, Sabi Sabi and Londelozi.FThe removal of the fence between the two parks allows the animals to move around freely and the game viewing experience is just as in the Kruger National with one important difference. Because this reserve is pri

22、vately held, off road game tracking is allowed which improves your chances of finding the elusive (难以找到的) big cats, elephant, rhino, buffalo and wild dog to a large degree. They also make use of two way radios in each safari vehicle so that if one finds something noteworthy the others can be alerted

23、.GThe sand and sabi rivers which bisect the reserve provide the focal point which attracts the wildlife to the area especially in the dry season. So viewing the big cats on a South Africa safari here is virtually guaranteed and the accommodation is some of the best in the world as illustrated by the

24、 Singita lodge which was the first and only accommodation in the history of the Conde Nast Gold List Reader Poll to get a perfect 100 score, an honour it has held for three years. There are about thirty different top class lodges situated in the reserve.HBut this all comes at a price and unless you

25、have reasonably deep pockets, this fantastic reserve will be out of reach which is why it doesnt get the No. one ranking for South Africa safari national parks and reserves.Hluhluwe Umfolozi National ParkIIf you want to see the endangered black and white rhinos in the wild then this is the park to h

26、ead for because this is where the unstoppable tide to extinction for the white rhino in Southern Africa was stemmed (遏制). It now boasts the largest population of white rhino in the world numbering over 1,600 and also a slowly increasing population of black rhino at just over 400.JOn a South Africa s

27、afari here you will also be able to see lion, leopard, buffalo, elephant and cheetah in this park and more than 400 bird species have been recorded. Due to the large number of resident elephants you might have some close encounters with them on the roads as they cross in front of you. You can go for

28、 a daffy walk in the park in the company of an armed ranger or you can do a several day extended hike in the southern Umfolozi portion.Madikwe Game ReserveKThis is a latter day Noahs ark story because most of the wildlife contained in this park was relocated here from other areas in 1991. Twenty sev

29、en different species amounting to over 10,000 head of game were re-introduced into this area where they once thrived but had disappeared because of hunting and habitat destruction. A huge advantage of taking a South Africa safari in this park is that it is not situated in a malaria area so you dont

30、have to bother about taking malaria tablets as you do in most other reserves.LAll of the big five are on view here as well as cheetah and the rare wild dog packs which are the stars of the show here being regularly sighted patrolling their huge territories. Your chances of seeing them seem to be bet

31、ter here than most other parks. Rare antelope like the eland, gemsbok and sable put in an appearance here too and you will be able to enjoy your wildlife viewing in relative peace and isolation because not many tourists know about this excellent game reserve.Kgalagadi Transfrontier ParkMThe locals k

32、now that this is an excellent game park and it falls into that “best kept secret“ category that each country seems to have where for some unknown reason a reserve doesnt get the notice from tourists and safari companies that it deserves. Maybe its because this reserve is set in the Kalahari desert a

33、nd people dont normally associate deserts with lots of wildlife but there are always exceptions to the rule and this South Africa safari park qualifies.NYou can see some pretty specialised and very interesting game here such as the gemsbok antelope which can go for months without water, springbok, b

34、lue wildebeest, eland and red hartebeest. And wherever there is a good supply of antelope, the predators are never far away such as the black maned lions which this area has a disproportionate supply off, leopard and cheetah which can make full use of the wide open spaces to chase their prey at top

35、speed.OThe meerkat (suricate) is also regularly seen here and bat eared foxes contribute to the scavenging duties. This South Africa park is famous for birds of prey such as the pygmy falcon and the sociable weaver which builds nests which are the bird equivalent of apartment blocks that are sometim

36、es so big they break the branches they rest on.PThere are hundreds of companies offering safari trips to South Africa. This Top Safari in South Africa operators list helps you choose effectively between them. South Africa safari trip reports give you a great idea of what to expect from a trip like t

37、his by learning from other peoples travel experiences.（分数：20.00）(1).When tourists want to have a daily walk in the Park, they must be escorted by an armed ranger.（分数：2.00）填空项 1:_(2).Tourists can closely experience wildlife in the northern part of the Park, because tourists there are comparatively fe

41、（分数：2.00）填空项 1:_(10).The reason why the Park doesnt get enough attention from tourists and safari companies might be that it is situated in desert.（分数：2.00）填空项 1:_七、Passage Two(总题数：1，分数：20.00)The Frontier HeritageThe Impact of the American FrontierAAlthough American civilization took over and replac

42、ed the frontier more than a century ago, the heritage of the frontier is still very much alive in the United States today. The idea of the frontier still stirs the emotions and imaginations of the American people. Americans continue to be fascinated by the frontier because it has been a particularly

43、 important force in shaping their national value.BThe frontier experience began when the first colonists settled on the east coast of the continent in the 1600s. It ended in about 1890 when the last western lands were settled.CThe American frontier consisted of the relatively unsettled regions of th

44、e United States, usually found in the western part of the country. Here, both land and life were more rugged and primitive than in the more settled eastern part. As one frontier area was settled, people began moving farther west into the next unsettled area. By settling one frontier area after anoth

45、er, Americans moved across an entire continent, 2,700 miles wide. How did this movement, which lasted more than two centuries, help to shape American values?DAmericans have tended to see the frontier, its life, and its people as the purest examples of their basic values. This has been the impact of

46、the frontier on the American mind. For example, the frontier provided many inspiring examples of hard work as forests were turned into towns, and towns into large cities. The race for competitive success was rarely more colorful or adventurous than on the western frontier. The rush for gold in Calif

47、ornia, for silver in Montana, and for fertile land in all the western territories provided endless stories of high adventure. When it was announced that almost two million acres of good land in Oklahoma would be opened for settlement in April 1889, thousands of settlers gathered on the border waitin

48、g for the exact time to be announced. When it was, they literally raced into the territory in wagons and on horseback to claim the best land they could find for themselves.EIndividualism, self-reliance, and equality of opportunity have perhaps been the values most closely associated with the frontier heritage of America. Throughout their history, Ame
