问题 多项选择题

假设开发法中开发完成后房地产出租或营业、自用的情况下,开发经营期为( )。

A.开发期+经营期

B.建设期+运营期

C.开发期+经营期-前期-建造期

D.前期+建造期+经营期

E.建设期+运营期-前期-建造期

答案

参考答案:B,E

解析: 开发经营期可分为建设期和经营期。
建设期,其起点与开发经营期的起点相同,终点为开发完成的房地产竣工的日期。建设期又可分为前期和建造期。
经营期根据开发完成后的房地产的经营方式而具体化。开发完成后的房地产的经营方式有销售、出租、营业。因此,经营期可以具体化为销售期(针对销售这种情况)和运营期(针对出租、营业、自用这些情况)。销售期是从开始销售开发完成房地产之日到其售出之日止的时间。在有预售的情况下,销售期与开发期有重合。运营期的起点通常是开发完成后的房地产竣工之日,终点是开发完成后的房地产经济寿命结束之日。

Even plants can run a fever, especially when they are under attack by insects or disease. But (1) humans, plants can have their temperature (2) from 3,000 feet away—straight up. A decade ago, (3) the infrared scanning technology developed for military purpose and other satellites, physicist Stephen Paley (4) a quick way to take the temperature of crops to determine (5) ones are under stress. The goal was to let farmer (6) target pesticide spraying (7) rain poison on a whole field, which (8) include plants that don’t have the pest problem.

Even better, Paley’s Remote Scanning Services Company could detect crop problem before they became (9) to the eye. Mounted on a plane flown at 3,000 feet (10) , an infrared scanner measured the heat emitted by crops. The data were (11) into a color-coded map showing (12) plants were running "fevers". Farmers could then spot spray, using 50 to 70 percent less pesticide than they (13) would.

The bad news is that Paley’s company closed down in 1984, after only three years. Farmers (14) the new technology and long-term backers were hard (15) . But with the renewed concern about pesticides on produce, and refinements in infrared scanning, Paley hopes to (16) into operation. Agriculture experts have no doubt about the technology works. "This technique can be used (17) 75 percent of agricultural land in the United States," says George Oerther of Texas A&M. Ray Jackson, who recently retired from the Department of Agriculture, thinks (18) infrared crop scanning could be adopted by the end of the decade. But (19) Paley finds the financial backing (20) he failed to obtain 10 years ago.
