读下面的短文，把方框内的数量词填入短文内
Pinatubo awoke on 1 ．Hot ash and gas flowed down the hillside and ash clouds rose 2 into the atmosphere．
On the volcano’s slopes, seven cubic kilometers of pulverized(成粉末状)rock now lay in drifts(漂流) 3 feet thick, totally reshaping the landscape．
One of the first dangers is falling debris(残骸)collecting on houses and causing roofs to collapse(塌陷)．In fact that was the main killer for this eruption．The eruption had come with the annual Typhoons that regularly swept the Islands．Heavy rainfall hit the hot and loosely packed volcanic debris．It was to be the start of a terror(恐怖)that would kill the people here long after the eruption stopped．
Imagine a truck delivering wet concrete(混凝土)．But expand that material to 4 cubic meters of debris-all moving at the same time-and you have a Lahar(火山泥石流)．
40 kilometers downstream from Mount Pinetubo is the town of Bacalor．Years after the eruption stopped, this town still suffers the onslaught(冲击)of Lahars．Most of its population of 5 have departed to resettlement camps．
About 6 of the population of Bacalor never left．They had been warned many times but the people remained．They seemed to be there forever．
Every year when the rains come new Lahars swamp(淹没)the town raising the land ever higher．Still people rebuild their homes．
Some of them have houses twice or even three times．And some people gave up, and others raised it 7 ．
Bacalor was originally a township of twenty-one large villages．Today only 8 remain．
The broken remains of Mount Pinetubo are silent now．But its volcanic ash lay heavy on its slopes．Just 9 of heavy rain, can produce a Lahar．It is not unusual to have eighteen Typhoons a year．So Philippine scientists constantly monitor(检测)the weather on the mountain’s slopes．Since the eruption, 10 Lahars have occurred, and all resulted from Typhoon rain．To reduce its damage, a huge system has now been constructed．

A long time ago, when ancient Rome was still an empire, people of that time used same weights and measures. The standards(标准)of those weights and measures were found by the Romans, who kept these standards in a temple in Rome. All standards for measuring weight or distance were the same, whether in Spain or in Syria. But then the Rome Empire fell, and these standards disappeared. Today, standards are different from place to place throughout the world.
Tourists who drive from the United States into Canada, for example, are surprised when they buy gas for their cars.
A gallon (加仑) of gas cost more than they are used to paying.They complain (抱怨) that prices are much higher in Canada than in the United States. Then they discover that they can drive farther on a Canadian gallon than on a United States gallon.
Is it a different kind of gas? No, it is a different kind of gallon. Canada used the British gallon that is about one-fifth larger than the United States gallon. Four quarts (夸脱) equal a gallon and two pints (品脱) equal a quart in both countries. But Canada's quarts and pints are larger than quarts and pints in the United States. The gallon equals 277.42 cubic (立方) inches while the gallon in the United States is equal to 231 cubic inches. Measured in ounces (盎司), Canada's larger gallon holds 160 fluid ounces, while the smaller United States gallon holds no more than 128 fluid ounces.From these figures, it is easy to see why Americans can drive farther on the Canadian gallon than on the American gallon.
Some day, countries may follow the example of the ancient Romans and make weights and measures the same for every nation.
(1) The whole passage tells about __________. ［ ］ A. the standards for weights and measures found by Romans B. the gallon in Canada and the United States C. surprised tourists in Canada D. the larger American gallon (2) The British gallon is about __________ larger than the United States gallon. ［ ］ A. 277.42 cubic inches B. 160 fluid ounces C. 128 fluid ounces D. 1/5 (3) Which statement does the passage lead you to believe? ［ ］ A. It would be good to use the same measure in the whole world. B. The Americans hate the Canada gas. C. The Canadian gas is better than the United States'. D. Buying gas in Canada is more expensive than in the United States.
(4) Six United States' gallons of liquid is about _________
British gallons of liquid. ［ ］
A. seven B. four C. five D. three
(5)After reading this passage, you can have an impression that __________ . ［ ］ A. different measures can be a problem B. people like different measures C. there are all kinds of measures in the world D. Americans should not travel too much

Faced with the threat of-water shortages, Beijing and Shanghai will take effective measures to save water and protect water resources.
Beijing will stick more strictly to water saving policies through the readjustment（重新调整）of industrial structures. Beijing is expected to be short of 1, 185 billion cubic meters of water by 2020. Beijing will shut down factories with high water consumption（消耗）and pollution including electric power, steel and paper manufacturing equipment. Advanced and water-saving technology will be introduced to new industrial projects in the capital city.
Grain-growing areas will be reduced to save ground water and more trees will be planted. Animal breeding and other “high efficient” agriculture with modern water-saving irrigation methods will be developed.
It is said that water used in agriculture will drop to 35 percent of the city's water consumption in 2010 from 43 percent in 1998, and the figure will continue to drop to28 ~ 30 percent in 2020. Beijing will increase the speed of renovation（修复）of its urban water supply equipment. It is reported that more than 15 percent of water is lost during distribution（分发）. Water-saving equipment and efficient management can save Beijing more than 537 million cubic meters by 2010.
Shanghai still faces key problems connected with its water resources and environments. Since 1998, the city has invested nearly US $169 million to treat its rivers, especially Suzhou Creek. The city's rivers have become noticeably clearer since putting it into action.
The government will provide a further US $ 24 million for the treatment of rivers and US $12 million to treat sewage（污物）.
This year's task is to improve the water quality at the three ports of Longhua, Yangshupa and Hongkou. Another emphasis to raise the water system is Songjiang New Area with a project worth US $ 4.8 million. Efforts will be made to improve public awareness about the need to protect water resources.
（1）How many measures has Beijing taken to save water and protect water resources?
[ ]
（2）Grain-growing areas in Beijing will be reduced because ________.
[ ]
A. grain can't fetch a good price in China
B. a lot of ground water will be saved by this means
C. Beijing helps to develop advanced technology
D. highly effective agriculture needs less farmland
（3）Beijing can save over 537 million cubic meters by 2010 by means of ________.
[ ]
a. water-saving equipment
b. effective management
c. artificial rain fall
d. reducing water pollution
（4）The author wrote the passage to tell us ________.
[ ]
A. Beijing and Shanghai are short of water
B. to save every drop of water in our daily life
C. big cities like Beijing and Shanghai are trying their best to protect water resources
D. water shortages have become one of the most important problems that China has to deal with
