M crops hold for farmers? GM crops can be produced to be herbicide (除草劑) resistant. This means that farmers could spray these crops with herbicide and kill the weeds, without affecting the crop. In effect, the amount of herbicide used in one season would be reduced, with a subsequent reduction in costs for farmers and consumers. Biotechnology panies are even experimenting with crops that can be genetically modified to be drought and salttolerant, or less reliant on fertilizer, opening up new areas to be farmed and leading to increased productivity. However, the claims of less herbicide usage with GM crops have till now not been independently supported by facts. Better quality foods Even animals can be genetically modified to be leaner, grow faster, and need less food. They could be modified to have special characteristics, such as greater milk production in cows. These modifications again lead to improved productivity for farmers and finally lower costs for the consumers. Modified crops could perhaps prevent outbreaks such as foot and mouth disease, which has badly influenced many farmers and local economies. No such products have been released to date。s ecosystems, the debate over their release will continue. Living organisms are plex and tampering with their genes may have unintended effects. It is in our mon interest to support concerned scientists and organizations, such as Friends of the Earth who demand required labeling of these food products and independent testing for safety and environmental impacts.1. What is the main difference between conventional breeding and genetic breeding?A) The former is based on sexual reproduction between like organisms while the latter can have genes even from bacteria and viruses.B) The former is unpredictable while the latter is predictable.C) The former is applied by farmers while the latter by scientists.D) The former has a long history while the latter a short one.2. Which of the following is the possible benefit of GM crops?A) They can be herbicideresistant. B) They can fertilize the field.C) They can produce salt. D) They can be more delicious.3. What will probably happen to the genetically modified animals?A) They may grow slower. B) They may improve the production.C) They may digest more food. D) They may spread disease quickly.4. What can we learn from GM salmon according to the passage?A) It can grow very slowly.

Scientists relied on Marker genes to test the results of __________. 10. Friends of the Earth claim that all GM food should be tested for__________. Questions 47 to 56 are based on the following passage.More than forty women have been killed in the war in Iraq. Hundreds of others have been ___ war began in March of 48___published books tell two different stories of women who served in Iraq. One is by Janis Karpinski. She was the Army general who ___ 49___military police at prisons in Iraq. These included the Army Reserve soldiers who ___ 50___ the Abu Ghraib Prison near Baghdad. Some have received prison ___51_for mistreating prisoners at Abu Ghraib. Miz Karpinski became the highestlevel officer to be punished in connection with the ___ left the service in July after being reduced from a brigadier general(準(zhǔn)將) to a colonel(上校).Her book is called “One Woman39。s process for converting iron into steel, which made the material more mercially feasible.Iron was rapidly adopted for the construction of bridges, because its strength was far greater than that of stone or timber, but its use in the architecture of buildings developed more slowly. By 1800 a plete internal iron skeleton for buildings had been developed in industrial architecture replacing traditional timber beams, but it generally remained concealed. Apart from its low cost, the appeal of iron as a building material lay in its strength, its resistance to fire, and its potential to span vast areas. As a result, iron became increasingly popular as a structural material for more traditional styles of architecture during the nineteenth century, but it was invariably concealed.Significantly, the use of exposed iron occurred mainly in the new building types produced by the Industrial Revolution: in factories, warehouses, mercial offices, exhibition halls, and railroad stations, where its practical advantages far outweighed its lack of status. Designers of the railroad stations of the new age explored the potential of iron, covering huge areas with spans that surpassed the great vaults of medieval churches and cathedrals.

The couple have made only a few carefully staged public appearances to reduce the scrutiny (仔細(xì)檢查).Spanish people waited for more than a decade for the 36yearold son of King Juan Carlos and Queen Sofia to find a suitable bride.
