D
The eruption of a volcano in the Canary Islands could trigger a “mega-tsunami”(巨大海啸)that would hit Atlantic coastlines with waves as high as 330 feet, scientists said on Wednesday. They said an eruption of the Cumbre Vieja volcano on La Palma, part of the Spanish island chain off West Africa, was likely to cause a massive chunk(大块)of rock to break off, crashing into the sea and kicking up huge walls of water higher than any other in recorded history. The tsunami would be capable of traveling huge distances at up to 500 miles an hour, the scientists said in a research paper to be published soon.
Simon Day, of the Benfield Greig Hazard Research Centre at the University College of London, said that as the volcano was not erupting at present, the short-term and medium-term risks were “negligible”. But Cumbre Vieja should be monitored closely for any signs of activity so that emergency services could plan an effective response, he said. “Eruptions of Cumbre Vieja occur at intervals of decades to a century or so and there may be a number of eruptions before its collapse(倒塌),” said Day, who cooperated on the research with Steven Ward of the University of California. “Although the year-to-year probability of a collapse is therefore low, the resulting tsunami would be a major disaster with indirect effects around the world.”
The effects would spread north, west and south of the Canaries, with the west Sahara bearing the worst of the wave’s energy. The energy released by the collapse would be equal to the electricity consumption of the entire United States in half a year.
Immediately after the landslide(山崩),a huge wave of water 93,000 feet high and tens of miles wide would form. As the landslide rocks moved deeper under water, a tsunami would develop. Within 10 minutes, the tsunami would have moved a distance of almost 155 miles. On the west Saharan shore, waves would probably reach heights of 330 feet.
Florida and the Caribbean, the final north Atlantic destinations to be affected by the tsunami, would have to brace themselves for 165-foot waves some eight to nine hours after the landslide. Wave heights toward Europe would be smaller, but substantial waves would hit the coasts of Britain, Spain Portugal and France. The research paper estimated water would penetrate several miles inland and that the devastation would cause trillions of dollars in damage.
76. What would be the result of a big chunk rock falling into the sea?
A. Waves would be very high.                                         B. The volcano would stop.
C. Walls of water would kick up a storm.                          D. An earthquake would take place.
77. The word “negligible”(Line 3, Paragraph 2) is closest in meaning to ______.
A. unimportant                    B. small                              C. predictable               D. avoidable
78. From the passage we may learn that the volcano erupts ______.
A. every year                                                                 B. every 5 to 9 years
C. every 10 to 100 years                                                        D. every 5 to 10 months
79. All of the following are true EXCEPT ______.
A future eruption of Cumbre Vieja volcano may experience a massive collapse
Waves generated by the landslide could even reach the coasts of the United States
The landslide-released energy is equal to half a year’s electricity consumption in the US
American scientists have managed to utilize the volcanic energy for civil purposes

It doesn"t take a rocket scientist long time to figure out that there are better things you could do for your health than take deep breaths on a smoggy(烟雾的)day. A growing pile of research suggests that even relatively low levels of air pollution may be more harmful than previously realized, to both heart and lungs(肺). The latest articles from researchers, published this week in the New England Journal of Medicine, focuses on how particulate (微粒) matter from air pollution affects lung function.
“The effect of low levels of particulate pollution found in many urban areas is not unlike secondhand smoke,” experts say. Studies show that short-term effects from particulates include diminished(减少) lung function, coughing, wheezing, and heart attacks. Long-term exposure can also slow normal lung growth, damage lung airways, and increase the risk of dying from lung cancer.
Certain populations, such as the very old and the very young, are the most vulnerable to air pollution. However, even the most alarming studies conducted in the most polluted areas suggest that the average person"s individual risk from exposure (暴露) is very slight. Relative risk numbers often seem more frightening than they actually are. For example, an earlier study published in the New England Journal of Medicine found that short-term exposure to traffic fumes tripled ( 成为3倍) the risk of heart attacks in heart-attack survivors.
Short of moving to the countryside or at least away from busy roads, shielding yourself from the effects of air pollution is not easy. Masks won"t work. “At the very least,” suggests Murray Mittleman, a cardiologist at Harvard University, “people who regularly exercise outdoors near highways may want to consider remapping their route.”
66. What does the underlined sentence in the first paragraph mean?
A. Rocket scientists are making researches on people’s health.
B. It"s obvious that air pollution has a bad effect on people’s health.
C. People aren"t sure whether taking deep breaths on a smoggy day is bad.
D. People often have a hard time when taking deep breaths on a smoggy day.
67. The word "vulnerable" in Paragraph 3 probably means _________.
A. easy to be hurt            B. easy to be protected
C. easy to be used            D. easy to be saved
68. The main idea of Paragraph 3  is _________.
A. that even small risk from particulate causes big problems
B. that air pollution often leads to heart attack
C. who are most likely to get affected
D. that we shouldn"t worry about the average low risk
69. In order to be healthier, you"d better _________.
A. take deep breaths         B. wear a mask   
C. live in a countryside       D. clean the busy road
70. The passage is written in a(n) _________ tone.
A. subjective         B. humorous     C. doubtful      D. objective
