In terms of Mans brief life it appe
21、ars permanent and unchanging, save for the seasonal growth and fall of the leaves, but to the forester it represents the climax of a long succession of events.No wooded landscape we see today has been forest for all time. Plants have minimum requirements of temperature and moisture and, in ages past
22、, virtually every part of Earths surface has at some time been either too dry or too cold for plants to survive. However, as soon as climatic conditions change in favour of plant life, a fascinating sequence of changes occurs, called a primary succession.First to colonize the barren land are the low
23、ly lichens, surviving on bare rock. Slowly, the acids produced by these organisms crack the rock surface, plant debris accumulates, and mosses establish a shallow root-hold. Ferns may follow and, with short grasses and shrubs, gradually form a covering of plant life. Roots probe even deeper into the
24、 developing soil and eventually large shrubs give way to the first trees. These grow rapidly, cutting off sunlight from the smaller plants, and soon establish complete dominationclosing their ranks and forming a climax community which may endure for thousands of years.Yet even this community is not
25、everlasting. Fire may destroy it outright and settlers may cut it down to gain land for pasture or cultivation. If the land is then abandoned, a secondary succession will take over, developing much faster on the more hospitable soil. Shrubs and trees are among the early invaders, their seeds calmed
26、by the wind, by birds and lodged in the coats of mammals.For as long as it stands and thrives, the forest is a vast machine storing energy and the many elements essential for life.（分数：10.00）(1).Why does the forest strike mankind as permanent?A.

30、总题数：1，分数：5.00)Direct advertising includes all forms of sales appeals, mailed, delivered, or exhibited directly to the prospective buyer of an advertised product or service, without use of any indirect medium, such as newspapers or television. Direct advertising logically may be divided into three br
31、oad classifications, namely, direct-mail advertising, mail order advertising, and unmailed direct advertising.All forms of sales appeals that are sent through the mails are considered direct-mall advertising. The chief functions of direct-mail advertising are to familiarize prospective buyers with a
32、 product, its name, its maker, and its merits and with the products local distributors. The direct-mall appeal is designed also to support the sales activities of retailers by encouraging the continued patronage of both old and new customers.When no personal selling is involved, other methods are ne
33、eded to persuade people to send in orders by mail. In addition to newspapers, magazines, radio, and television, other special devices, order promotions are designed to accomplish a complete selling job without salespeople.Used for the same broad purposes as direct-mail advertising, unrolled direct-m
34、ail advertising, includes all forms of indoor advertising displays and all printed sales appeals distributed from door to door, handed to customers in retail stores or conveyed in some other manner directly to the recipient.With each medium competing keenly for its share of the business, advertising
35、 agencies continue to develop new techniques for displaying and selling wares and services. Among these techniques have been vastly improved printing and reproduction methods in the graphic field, adapted to magazine advertisements and to direct-mail enclosures; the use of color in newspaper adverti
36、sements and in television; and outdoor signboards more attractively designed and efficiently lighted. Many subtly effective improvements are suggested by advertising research.（分数：5.00）(1).Direct advertising _.A. includes all forms of sales appeals to the prospective buyerB. is produced mainly for ne
37、wspaper or televisionC. is an activity by which real products are shown to buyersD. uses post as a chief means to contact prospective buyers（分数：1.00）A.B.C.D.(2).Direct-mail advertising _.A. uses letters as a chief means of providing informationB. sends old customers detailed information about new pr
38、oductsC. uses letters to tell prospective buyers about the local sellersD. sends over the prospective buyers sample products by parcels（分数：1.00）A.B.C.D.(3).The word “prospective“ in the first sentence of the passage means _.A. would be B. prosperousC. rich D. old（分数：1.00）A.B.C.D.(4).The chief functi
39、on of unmailed advertising is _.A. to send sample products from door to doorB. to familiarize the customers with the productsC. to deliver the products directly to the retail storesD. to send information about the products in quick ways（分数：1.00）A.B.C.D.(5).From the last paragraph we learn _.A. direc
40、t advertising is the best way to promote a productB. companies are trying to find the best way to sell their productsC. advertising is becoming enriched by the research in this areaD. old ways of advertising is giving ways to new ways of doing it（分数：1.00）A.B.C.D.五、Passage Three(总题数：1，分数：8.00)I saw a
41、 television advertisement recently for a new product called an air sanitizer. A woman stood in her kitchen, spraying the empty space in front of her as though using Mace against an imaginary assailant. She appeared very determined. Where others are satisfied with antibacterial-laced sponges, dish so
42、aps, hand sanitizers and telephone wipes, here was a woman who sought to sterilize the air itself.As a casual student of microbiology, I find it hard to escape the absurdity here. This woman is, like any human being, home to hundreds of trillions of bacteria. Bacteria make up a solid third, by weigh
43、t, of the contents of her intestines. If you were to sneak into her bathroom while she was showering-and based on my general impression of this woman from the advertisement, I dont recommend this-and secret away a teaspoon of the water at her feet, you would find some 820 billion bacteria. Bacteria
44、are unavoidably, inevitably-and, usually, utterly benignly-a part of our world.The fantasy of a germ-free home is not only absurd, but it is also largely pointless. Unless you share your home with someone very old, very young (under 6 months) or very ill, the few hundred bacteria on a countertop, do
45、orknob or spoon pose no threat. The bacteria that cause food poisoning, the only significant rational bacterial worry in the average home, need to multiply into the thousands or millions before they can overwhelm your immune system and cause symptoms.The only way common food poisoning bacteria can m
46、anage this is to spend four or five hours reproducing at room temperature in something moist that you then eat. If you are worried aboutfood poisoning, the best defense is the refrigerator. If you dont make a habit of eating perishable food that has been left out too long, dont worry about bacteria.
47、Viruses are slightly different. You need only pick up a few virus particles to infect yourself with a cold or flu, and virus particles can survive on surfaces for days. So disinfecting the surfaces in the home should, in theory, reduce the chances of picking up a bug.In practice, the issue is less c
48、lear. A study by Dr. Elaine Larson at the Columbia School of Nursing called into question the usefulness of antibacterial products for the home. In New York, 224 households, each with at least one preschooler, were randomly assigned to two groups. One group used antibacterial cleaning, laundry and h
49、and-washing products. The other used ordinary products For 48 weeks, the groups were monitored for seven symptoms of colds, flu and food poisoning-and found to be essentially the same. According to Dr. Gerbas research, an active adult touches an average of 300 surfaces every 30 minutes. You cannot win at this. You will become obsessive-compulsive Just wash your hands with soap and water a few times a day, and le
