15．Advertisements based on these facts in newspapers and magazines but they didn't help much．（　　）

	A．	had printed		B．	had been printed
	C．	have been printed		D．	was printed

分析根据这些情况制定的广告词已刊登在了报纸和杂志上，但是它们的效果并不大．

解答答案：C
分析句意可知，此处表示过去的动作或状态对现在产生的影响或造成的后果，即：大家都已经看到了刊登在报纸和杂志上的广告词，所以这里应使用现在完成时；故选C．

点评本题考查了现在完成时强调"影响性"的用法；做本题时，需要了解现在完成时除了强调动作的持续性以外，它还强调过去的动作对现在产生的影响以及造成的结果；例如：I have already seen the film．我已经看过这部电影了．（对现在的影响是：我知道电影的内容）；I have lost my key．我把钥匙弄丢了．（造成的结果是：我进不了门了．）

6．Contrary to most people's idea，the air in Coastal cities can be far from fresh and healthful，said a report recently published．
University of California Professor Mark Thiemens led the research team．His team．report blames ships that release dirty smoke by burning low-cost，high-sulfur （硫横）fuel．They directly measured smoke released from a ship．They also tested air at the end of the Scripps Pier （码头）．The area is just north of San Diego，which is both a major city and port．The Scripps Pier is also close to waters with heavy shipping traffic and the city of Los Angeles．Los Angeles has the third largest port in the world．
Primary sulfate （硫酸盐）is produced when a ship burns fuel called bunker oil．Bunker oil contains a Large amount of sulfur．Most sulfur released by ships burning bunker oil is a gaseous pollutant-sulfur dioxide．After a time，sulfur dioxide becomes sulfate in the atmosphere．The researchers say this primary sulfate may be only a small part of what ships produce．
Professor Thiemens said no one had really expected that ships would be responsible for so many，particulates （微粒）．He said the extremely small particles （撤粒）are especially threatening．They measure only one and one half microns in size．，A micron is one millionth of a meter．
The researchers say the particulates can travel long distances because they stay in the atmosphere longer than other pollutants．Professor Thiemens noted that the air of Los Angeles influenced air quality in San Die-go．That distance is almost 180 kilometers．，
Primary sulfur particulates can also threaten human health．When people breathe，the particulates stay in their lungs．Other scientists have said that up to 60，000 people around the world die each year from dirty ship smoke．
Other gaseous pollutants from ships include nitrogen oxide and carbon dioxide．Earlier this year，a United Nations'report said gases from ships produce more than one billion tons of carbon dioxide every year．Ships are not governed under the Kyoto Protocol，the agreement that establishes limits for gases linked to climate change．But international rules requiring ship fuels that burn cleanly are to become effective in 2015．
57．What is the main idea of the passage？B
A．Coastal cities are ideal places to live in．
B．The air quality in coastal cities is worrying．
C．Cleaner-burning fuels are welcome in ships．
D．The world's oceans'ecosystem is far from satisfactory．
58．It is generally thought thatA
A．the air in coastal cities'is very fresh and healthful
B．the air in coastal cities is badly polluted
C．ships are responsible for so many particulates
D．extremely small particles are harmless
59．Gaseous pollutants from ships mentioned in the passage includeC
A．sulfate，nitrogen oxide and carbon dioxide
B．carbon dioxide and small particles
C．sulfur dioxide，nitrogen oxide and carbon dioxide
D．sulfate and micron
60．We can draw the conclusion thatD
A．the Kyoto Protocol is an agreement related to sea fish hunting
B．bunker oil has already been banned in passenger ships
C．urgent action should be taken to reduce the number of ships
D．cleaner-burning fuels should be encouraged to be used in tankers and passenger ships．
