A1. The following editorial appeared in the South Fork Gazette.
“Last year, the city contracted with Flower Power to plant a variety of flowers in big decorative pots on Main Street and to water them each week. By midsummer many of the plants were wilted. This year the city should either contract for two waterings a week or save money by planting artificial flowers in the pots. According to Flower Power, the initial cost for artificial flowers would be twice as much as for real plants, but after two years, we would save money. Public reaction certainly supports this position: in a recent survey, over 1,200 Gazette readers said that the city wastes money and should find ways to reduce spending.” Math: 碰到的jj:

They offer as evidence the fact that 90 percent of the projects canceled were in such districts. But all of the canceled projects had been identified as wasteful in a report written by respected nonpartisan auditors. So the President’s choice was clearly motivated by sound budgetary policy, not partisan politics. Which of the following is an assumption on which the press secretary’s argument depends? A. Canceling highway projects was not the only way for the President to punish legislative districts controlled by opposition parties.
B. The scheduled highway projects identified as wasteful in the report were not mostly projects in districts controlled by the President’s party.
C. The number of projects canceled was a significant proportion of all the highway projects that were to be undertaken by the government in the near future.
D. The highway projects canceled in districts controlled by the President’s party were not generally more expensive than the projects canceled in districts controlled by opposition parties.
E. Reports by nonpartisan auditors are not generally regarded by the opposition parties as a source of objective assessments of government projects. Answer: B GWD: A certain cultivated herb is one of a group of closely related plants that thrive in soil with high concentrations of metals that are toxic to most other plants. Agronomists studying the herb have discovered that it produces large amounts of histidine, an amino acid that, in test-tube solutions, renders these metals chemically inert. Possibly, therefore, the herb’s high histidine production is what allows it to grow in metal-rich soils A hypothesis that would gain support if ______. A: histidine is found in all parts of the plant – roots, stem, leaves, and flowers
B: the herb’s high level of histidine production is found to be associated with an unusually low level of production of other amino acids
C: others of the closely related group of plants are also found to produce histidine in large quantities
D: cultivation of the herb in soil with high concentrations of the metals will, over an extended period, make the soil suitable for plants to which the metals are toxic
E: the concentration of histidine in the growing herb declines as the plant approaches maturity. Answer: 此题有人选C有人选D SC:总体印象有难度，不记得了。 |
