1、（六）段意的概括归纳The 2012 London Olympics had enough problems to worry about. But one more has just been added - a communications blackout caused by solar storms.After a period of calm within the Sun, scientists he detected the signs of a flesh cycle of sunspots that could peak in 2012, just in time for the arrival of the Olympic torch in London.Now scientists beli that this peak could result in vast solar explosions that could throw billions of tons of charged matter towards the Earth, causing strong solar storms that could jam the ecommunications salites and interact links sending five Olympic broadcast from London.At the peak of the cycle, violent outbursts called coronal mass ejections (日冕物质抛射) occur in the Sun's atmosphere, throwing out great quantities of electrically-charged matter. " A coronal mass ejection can carry a billion tons of solar material into space at over a million kilometres per hour. Such nts can exe astronauts to a deadly amount, can disable salites, cause power failures on Earth and disturb communications," Professor Harrison added. The risk is greatest during a solar maximum when there is the greatest number of sunspots.Next week in America, NASA is scheduled to launch a salite for monitoring solar activity called the Solar Dynamics Observatory (SDO), which will take images of the Sun that are 10 times clearer than the most aanced evisions ailable.The Rutherford Appleton Laboratory ed to make the high-tech cameras that will capture images of the solar flares (太阳耀斑) and explosions as they occur.Professor Richard Hold away, the lab's director, said that the SDO should be able to provide early warning of a solar flare or explosion big enough to affect salite communications on Earth "If we he aance warning, we'll be able to reduce the damage. What you don't want is things switching off for a week with no idea of what's caused the problem," he said.72. The phrase "communications blackout" in paragraph 1 most probably refers to during the 2012 Olympics.B. the collapse of broadcasting sC. the transpoA. the extinguishing of the Olympic torchrtation breakdown in LondonD. the destruction of weather salites73. What can be inferred about the solar activity described in the passage?A. The most fatal matter from the corona falls onto Earth.B. The solar storm peak occurs in the middle of each cycle.C. It takes sral seconds for the charged matter to reach Earth.D. The number of sunspots declines after coronal mass ejections.74. According to the passage, NASA will launch a salite to _________.A. take images of the solar B. provide early warning of tderstorms75. Which of the following might be the best title of the passage?A. Solar Storms: An Invisible KillerB. Solar Storms: Earth Environment in DangerC. Solar Storms: Threatening the Human RaceD. Solar Storms: Human Activities to Be Troubled72. B. 此题线索为第二三段的内容。

2、73. D.74. C. 可从文章第六段直接得出。

3、75. D. 通读全文可知整篇文章讨论的是太阳运动所可能会带来的困扰。

4、我只找到一篇，你先看着O(∩_∩)O~。
