| Nuclear radiation from power plant leaks and bomb tests resulted in millions of fewer baby girls born worldwide, according to a new study. Scientists noted these types of atmospheric blasts rather than ontheground incidents like Chernobyl (切尔诺贝利), effected birth gender across the globe. Scientists at Helmholtz Zentrum M?nchen, Germany, analysed population data from 1975 to 2007 for the U. S. and 39 European countries. There was an increase in the number of baby boys relative to girls in all of the countries from 1964 to 1975. This was the case in many eastern European countries for several years after 1986. Scientists are putting the first spike down to the atomic bomb tests of the 1960s and 1970s where radioactive atoms were blasted into the atmosphere. Air currents caught these atoms and then distributed them around the world. They think the second spike is due to the 1986 Chernobyl disaster in which the reactor exploded in the Ukraine(乌克兰). The effects of Chernobyl were felt locally and no effect was seen in the U. S., probably because it was too far from the disaster to have an effect. "The closer the country was to Chernobyl, the stronger the effect, " said study coauthor Hagen Scherb, a biostatistician(生物统计学家) at the German Research Center for Environmental Health in Munich. More males were born relative to females in Belarus-the Ukraine's neighbour-than in France. The study is based largely on Cold Warera statistics, but the findings are highly relevant for how gender could be affected after future nuclear disasters. And in the wake of Japan's Fukushima Daiichi nuclear power plant accident experts are predicting another baby boy boom could come, especially on the U. S. West Coast. Previous radiation experiments on animals may give a clue for the increase in male births. Tests showed that radiation caused damage to the X chromosome(染色体) in sperm, Dr Scherb said. A human sperm cell contains either an X or Y chromosome, while an egg only has an X chromosome. An XY combination will become a boy, while an XX combination will be a girl. |

| A. The ontheground incidents like Chernobyl, effected birth gender across the globe. B. There was an increase in the number of baby boys in many eastern European countries for several years after 1986. C. The Japan's nuclear accident will not effect the birth gender of the U. S. because of the long distance. D. Where radioactive material has spread, women can't give birth to children |
| 3. How does radiation effect birth gender? |
| A. It damages the Y chromosome in sperm. B. It stops X chromosomes and Y chromosomes combining. C. It kills baby girls before they are born. D. It damages the X chromosome in sperm. |
| 4. What does the passage mainly tell us? |
| A. Nuclear age has led to millions of fewer baby girls being born. B. Nuclear radiation has bad effects upon people's health. C. Worries about radiation risks. D. Nuclear age helps reduce the world population. |

| A. The water supplying situation in Beijing B. Water wasting in businesses C. The consequence of the fierce drought in southeast of China D. The efficient measures saving water E. Much water is wasted from the old water facilities F. Some of the businesses should be forced to close up to save water 1. ________ The most severe drought in more than a century ravaging Southwest provinces should serve as a reminder to other parts of the country that they need to get prepared to avert the dangers from the water crisis, with more than 400 cities in need of water. 2. ________ Beijing is a case in point. With per capita water resources of only 180 cubic meters, shortage of water has been a permanent scourge(天灾). And what the city has done in saving on water is far from enough. 3. ________ A total of 220,000 tons of fresh water are wasted in flushing toilets every day. The amount of water leaking in a year from the old water supply pipelines is estimated to be about 70 Kunming Lakes at the Summer Palace. The 9,000 carwashing shops consume as much as 30 million cubic meters of water a year. 4. ________ In addition, the 38 golf courses around the city use 20 million cubic meters of water a year. And at least more than a million tons of water are needed to make artificial snow for the ski runs in the city's suburbs. The amount of water consumed by the more than 1,000 bathhouses is estimated at nearly 20 million tons. 5. ________ This situation is similar in other cities badly in need of water. There is much we can to do to save water. Of the 100 residential communities that have pipelines for treated water in Beijing, only 20 percent are using it to flush toilets. Why do we need so many golf courses to waste the precious fresh water? Why do we allow carwashing shops to waste fresh water rather than treated water to wash cars? Why does the government allow so many bathhouses and ski runs to operate? All these businesses are making money at the expense of our precious resource of fresh water. We can't afford to wait until it is too late. Do whatever we can to save water. |
