四、阅读理解

• 22．There has been a dramatic increase in the number of natural disasters over the past few years，and it is believed that global warming and climate change could cause even more disasters in the future.Some of the world's leading cities are facing disasters like floods and heat waves.
  London
     London's flood defences are getting older.Since 1982，the Thames Barrier（水闸） has protected the city from the threat of flooding，but it was only designed to last until 2030 and close once every two or three years.About 26 years later the barrier closes five or six times a year and according to Environment Agency predictions，by 2050 the barrier will be closed on almost every tide if the problem is not addressed.
     There are 26 underground stations，400 schools，16 hospitals，an airport and 80 billion worth of property in London's flood risk area，so large scale flooding would be disastrous.
  Paris
     Over a six-week period in July and August 2003，more than 11，400-mainly elderly people-died in France from dehydration（脱水） and extremely high body temperature in a deadly heat wave.Heat waves of similar intensity（强度） are expected every seven years by 2050.So what can be done to make sure such a disaster does not happen again？
     One solution is to have air conditioners installed in elderly care homes.But this is considered a short-term solution，as the increase in demand for electricity also increases carbon emissions.
     In Paris the local authorities are encouraging architects to design new types of buildings such as the building "Flower Tower"，which uses a covering of bamboo to act as a natural air conditioner.
  Shanghai
     Shanghai is one of the fastest growing cities on the Earth.It has a population of about 24 million and is only about 4 metres above sea level.Sea level is predicted to rise by 20cm within the next century.
  
  （1）What problem should be settled now in London？

  
  A．How to protect the city's property.
  B．Where to build its flood defences.
  C．How to use the Thames Barrier to protect the city.
  D．How to improve the function of the old flood defences.
  （2）Which of the following measures CAN'T solve the heat wave disaster in Paris？

  
  A．Putting up new types of buildings with a covering of bamboo.
  B．Having air conditioners installed in elderly care homes.
  C．Forbidding the city to build "Flower Tower".
  D．Encouraging architects to design new types of buildings.
  （3）The purpose of the passage is

  .
  A．to tell us how to protect the big cities
  B．to give advice on how to defend natural disasters
  C．to explain what causes floods and heat waves
  D．to warn us of the increasing natural disasters in big cities
  （4）Which of the following would be the best title for the passage？

  
  A．Big Cities Facing Big Disasters
  B．Big Disasters in the Future
  C．The Increase of Natural Disasters
  D．Solutions to Natural Disasters
