阅读下面短文,根据第73至第75小题的具体要求,简要回答问题。

The north magnetic pole(磁极)is no longer a resident of Canada.It has drifted across the Canadian Arctic and is now angling toward Siberia.

Not to be confused with the geographic North Pole—the northern extremity of the Earth’s axis(地轴),the north magnetic pole(where the Earth’s magnetic field is directed downward)is moving due to natural changes in the Earth’s magnetic field,a process that originates about 3000 kilometers below our feet,in the outer core(核心)of the planet.But scientists are now noticing that the magnetic pole has picked up its pace.

Over the past century,the pole has been migrating at an average speed of about 10 kilometers per year,says Larry Newitt,head of Geomagnetic Laboratory at Natural Resources Canada in Ottawa.Since the 1970s,this speed has increased to about 50 kilometers per year.

Scientists are wondering why the speed is increasing,says Newitt.One hypothesis(假说)relates it to “magnetic jerks”,sudden shifts(变化)in the rate of change of the magnetic field.There have been three jerks in the past four decades,each one correlating to an increases in speed.

If the north magnetic pole continues at its current rate,it could reach Siberia by 2056.

“For most of recorded history,the pole has been a part of Canada,and now it’s not,”says Newitt.“It may be a blow to our collective psyche,but other than that,it doesn’t have a major effect on most people’s existence.”

73.Find in the passage a word closest in meaning to the underlined word “angling”.

73.Moving/Migrating

74.It could reach Siberia

75.The north magnetic pole is moving faster.


解析:

73. 按照上下文意思“移动,迁移”。

74. 按照此段意思,应该总结为“能够达到西伯利亚”。

75. 抓住关键词:magnetic ,moving。

Tsunamis (海啸) are a series of huge waves created by an underground movement such as an earthquake or a volcanic eruption (火山喷发) . A tsunami can travel hundreds of miles per hour in the open ocean and hit the land with huge waves.

From the area where the tsunamis come, waves travel in all directions. Once the waves approach the coast, they will become more than 100 feet in height. The topography (地形) of the coastline and the ocean floor will influence the size of the wave. There may be more than one wave and the latter one may be larger than the one before. That is why a small tsunami at one beach can be a huge wave a few miles away.

All tsunamis are dangerous, even if they may not damage every coastline they strike. A tsunami can strike anywhere along most of the US coastline. Many harmful tsunamis have occurred along the coasts of California, Oregon, Washington, Alaska and Hawaii.

A movement of the ocean floor, caused by earthquakes, most often causes tsunamis. If a tsunami occurs close to a coast, the first wave could reach the beach in a few minutes, even before a warning is given. Areas are at greater risk if they are less than 25 feet above sea level and within a mile of the coastline. Drowning is the most common cause of death during a tsunami. Tsunami waves are very harmful to buildings. Other dangers include floods, pollution of drinking water, and fires from gas lines.

An accurate prediction (预报) system will allow authorities (官方) to issue timely warnings and save lives in the event of a shore-bound tsunami. But forecasting tsunamis accurately is very difficult because the ocean is usually calm before they strike land.

65. What can cause tsunamis according to the passage? ( 回答词数不超过6个 )

66. What harm can a tsunami bring besides killing people and damaging buildings? ( 回答词数不超过15个 )

67. Why is it very difficult to forecast tsunami accurately ? ( 回答词数不超过9个 )

阅读下面短文,根据73-75题的具体要求,简要回答问题。

Shanghai is the largest city in China. About eleven million people make their homes in Shanghai and its suburbs. This extremely large city spreads out along the banks of the Huang Pu River, which flows into the mouth of the Yangtze River about fourteen miles north of here. Large oceangoing ships travel to Shanghai by way of the Yangtze and the Huang Pu.

Shanghai was a small, unimportant city until 1842 when China lost a war with Great Britain. The British realized that Shanghai was in an excellent location to serve as a seaport for the densely(密集) populated Yangtze River Plain. They forced the Chinese to allow English traders to settle on the wastelands outside the city walls. Later, French, American, and Japanese traders also came to Shanghai. The foreigners built whole new sections of Shanghai, including homes, stores, factories, and office buildings. Thousands of Chinese poured into Shanghai in search of jobs. Most of them settled in the old part of the city. As time passed, shanghai became one of the busiest seaports in the world.
