三、阅读理解

• 3．Is running a marathon （马拉松） under two hours possible？Will a human ever be able to run that fast？Now，the world record for the 42.195km（26.219 miles）distance is held by the Kenyan runner Eliud Kipchoge.His time of 2：01：39 hours was achieved at the Berlin Marathon of 2018.
     But studies published in the past have come to the conclusion that running a marathon under 2 hours can be done.They even see a time of around 1：57 as the fastest a human can ever run.However，we may have to wait longer for this to happen.
     To achieve an under two-hour marathon，an athlete would have to have the perfect body size and weight，the right running plans and of course，the right nutrition（营养）.Today's perfect runners come from Kenya and Ethiopia，countries that have dominated（占优势）long distance races for years.East African athletes have long legs and lungs that can take in lots of oxygen（氧）.Training at high altitudes（海拔）gives them a strong heart.Ideal weather conditions with cool temperatures and no wind will also be needed to attempt such a mark.An extremely fast marathon would only be possible on flat city courses，like Berlin or London.
     Since the beginning of the modern Olympic Games in 1896，athletes have tried to run long distance races as fast as possible.In 1900，the marathon world record was at around 3 hours.In the following 30 years，men were able to reach a mark of 2：30.But in the last 15 years，the world record has improved by only 3 minutes.
     On the other side，some experts think that such fast performances will only be possible with the help of some medicine.
  
  （1）Why is the world record mentioned in Paragraph 1？

  
  A．To show a human can run very fast.
  B．To prove Eliud Kipchoge is the best.
  C．To introduce the greatest success in the world.
  D．To show an under two-hour marathon hasn't been achieved yet.
  （2）Why is it difficult to see a time of around 1：57？

  
  A．It requires too many things to fit together.
  B．It isn't easy to find right running plans.
  C．Training a perfect runner takes a long time.
  D．Kenyan and Ethiopian runners control marathons.
  （3）Which of the following may be important for an under two-hour marathon？

  
  A．High altitudes.
  B．Lots of oxygen.
  C．A perfect environment.
  D．Tall and strong runners.
  （4）What can we learn from Paragraph 4？

  
  A．Men will run faster and faster.
  B．Men made the greatest progress in 1930.
  C．Achieving shorter time became more difficult.
  D．It's impossible to break the marathon world record.
