1、2014高考英语阅读理解基础二轮训练题(2)及答案【2014高考英语湖北省汉阳市联考试题】400-year-old plants from the Little Ice Age were brought back to life, which could help us understand how the Earth will deal with climate change.Moss(藓类植物) found buried beneath the Teardrop glacier(冰川) on Ellesmere Island in Canada has been brought back
2、to life. Findings suggest that these plants could help repopulate regions exposed by melting ice caps. Plants that were buried beneath thick ice in Canada more than 400 years ago and were thought to have frozen to death have been brought back to life by Canadian scientists.Samples of the moss plant,
3、 covered by the glacier during the Little Ice Age of 1550 to 1850 AD, were replanted in a lab at the University of Alberta and grew new stems(茎). Researchers now think these findings can give indication as to how regions can recover as the ice covering them melts.Biologist Dr. Catherine La Farge and
4、 her team at the University of Alberta were exploring the region around the Teardrop glacier on Ellesmere Island. Ice on Ellesmere Island region has been melting at around four meters each year for the past nine years. This means that many areas of land that were previously covered by ice have since
5、 been exposed. Many ecosystems that were thought to have been destroyed during the Little Ice Age between 1550 and 1850 AD can now be studied, including many species that have never been studied before.While examining an exposed area of land, La Farge and her team discovered a small area of moss cal
6、led Aulacomnium turgidum. It is a type of bryophyte(苔藓类植物) plant that mainly grows across Canada, the US and the Highlands of Scotland.Dr La Farge noticed that the moss had small patches of green stems, suggesting it is either growing again or can be encouraged to repopulate. Dr La Farge told the BB
7、C, “When we looked at the samples in detail and brought them to the lab, I could see some of the stems actually had new growth of green branches, suggesting that these plants are growing again, and that blew my mind. When we think of thick areas of ice covering the landscape, weve always thought tha
8、t plants have to come from refugia(濒绝生物保护区), never considering that land plants come from underneath a glacier. Its a whole world of whats coming out from underneath the glacier that really needs to be studied. The ice is disappearing pretty fast. We really have not examined all the biological syste
9、ms that exist in the world; we dont know it all.”Dr La Farge took samples of the moss and, using carbon-dating techniques, discovered that the plants date back to the Little Ice Age. Dr La Farges team took the samples, planted them in dishes full of nutrient-rich potting soil and fed them with water
10、.The samples were from four separate species including Aulacomnium turgidum, Distichium capillaceum, Encalypta procera and Syntrichia ruralis. The moss plants found by Dr La Farge are types of bryophytes. Bryophytes can survive long winters and regrow when the weather gets warmer.However, Dr La Farg
11、e was surprised that the plants buried under ice have survived into the twenty-first century. Her findings appear in proceedings(论文集)of the National Academy of Sciences.59. Dr La Farges research is of great importance to _.A. knowing what the plants during the Little Ice Age were likeB. understandin
12、g how ecosystems recover from glaciers.C. regrowing many species that have been destroyed before.D. figuring out the effects of melting ice caps on moss.60. The underlined part “blew my mind” in Paragraph 6 can best be replaced by “_”.A. surprised me B. greatly frightened me C. put my doubt out of m
13、y mind D. was exactly what I had in my mind61. According to the passage, Aulacomnium turgidum _.A. lives better in small groups B. is very active in hot weatherC. is strong enough to survive coldness D. is chosen from Canadian refugia62. Which of the following would be the best title for the passage
14、?A. Bryophyte ecology is greatly affected by climate change.B. 400-year-old mosss survival is a mystery to solve.C. Moss in ancient times was discovered in Canada.D. 400-year-old plants were brought back to life.【参考答案】59、 61-62 Passage Thirty (Fingerprints) The search for latent prints is done in a
15、systematic and intelligent manner. Investigators develop techniques to locate traces of fingerprints at a crime scene. The basic premise in searching for latent prints is to examine more carefully those areas, which would most likely be touched by persons who have been on the scene. The natural mann
16、er in which a person would use and place his hands in making an entrance or exit from a building or in handling any object is the key to the discovery of latent prints. Where a forced entrance has been made, latent prints are likely to be found on any surface adjacent to or at that point. Any object
17、 with a smooth, non-porous surface is likely to retain latent prints if touched. Fingerprints on rough surfaces are usually of little value. If the fingermark does not disclose ridge detail when viewed under a reading glass, the chances are that its value in identification is nil when photographed.
18、Where fingermarks are found, it will be necessary for the investigator to compare them against the ones of persons having legitimate access to the premises so that the traces might be eliminated as having evidentiary value if they prove to be from these persons. Places to search for prints on an aut
19、omobile are the rear view mirror, steering wheel hub, steering column, windshield dashboard and the like. Dusting of surface may be done with a fine brush or with an atomizer. The whit powders used are basically finely powdered white lead, talc, or chalk. Another light powder is basically Chemists g
20、ray. A good black powder is composed of lampblack, graphite, and powdered acacia. Dragons blood is good powder for white surface and can be fixed on paper by heating. In developing latent prints, the accepted method is to use the powder sparingly and brush lightly. Do not use powder if the fingermar
21、k is visible under oblique lighting. It can be photographed. A good policy for the novice is to experiment with his own prints on a surface similar to the one he wishes to search in order to determine the powder best suited to the surface. Fingerprints after dusting may be lifted by using fresh cell
22、ulose tape or commercially prepared material especially designed to lift and transfer dusted latent fingerprints. In addition to latent prints, the investigator must not overlook the possibility of two other types of fingerprint traces: molded impression and visible impression. Molded impressions ar
