Following a successful three-month training period in the United States, the 31-year-old will chase a third title on Sunday after her first victory in 2002 and again 12 months later.Radcliffe clocked a time of 2:18:56 in her first 42.2-kilometer race three years ago.Afterwards she set a "mixed course" mark of 2:17:18 five months later in Chicago before lowering that to a time of 2:15:25 in the 2003 London event.小题1:Radcliffe’s failure in Athens made her       .A．develop respect for Liz.B．love people around her more.C．rest for five months.D．face criticism calmly.小题2:Which of the following is true according to the passage?A．Radcliffe broke the world record in the New York City marathon.B．Radcliffe didn't fully recover before the New York City marathon.C．Radcliffe won her first marathon title in the New York City marathon.D．Radcliffe had a 3-month training before the New York City marathon.小题3:By saying “I can't put a number on it,” Radcliffe means she’s not sure        .A．if she has the ability to set a new world record.B．if she can win another race though she has won many times.C．how many times a marathon runner can set the world record.D．if she has the ability to produce four or five world-class times.小题4:What can we learn from Radcliffe's story?A．Practice makes perfect.B．Well begun is half done.C．A friend in need is a friend indeed.D．Where there is a will there is a way.
