Recently a new research has been reported. It said that many fathers of children experienced lots of injuries per year while playing with {#blank#}1{#/blank#} (they)children. Some fathers felt that it was the most dangerous thing of being a parent walking across the floor {#blank#}2{#/blank#} (cover)by toys. And some of them fell over because clothes or other things{#blank#}3{#/blank#} (throw)everywhere. Besides, {#blank#}4{#/blank#} third of fathers were knocked down by their young children when fighting with them and a quarter got hurt when playing football or climbing trees with them. In fact, one {#blank#}5{#/blank#} five young fathers picked up an injury when doing something that wasn't suitable for them.

    The research also found that some of the fathers who were  {#blank#}6{#/blank#} (serious)injured had to take time off work. {#blank#}7{#/blank#},not all of them had medical insurance(保险)in place {#blank#}8{#/blank#} (prevent)the case that they were too ill to work. And they were more likely to face a situation {#blank#}9{#/blank#}their mobile phones and holiday bookings declined sharply during illness. So the fathers took much {#blank#}10{#/blank#} (press)from both the family and the work.

    Chris is not a traditional explorer— he usually {#blank#}1{#/blank#} (work) in an office for a large organization. However, Chris' job can be just {#blank#}2{#/blank#} exciting and dangerous as being an explorer.

    Chris is a doctor from France and he works for MSF,{#blank#}3{#/blank#} is also known as Doctors Without Borders. MSF sends its doctors all over the world {#blank#}4{#/blank#}(help) people after a war or a disaster. The organization received the Nobel Peace Prize in 1999.

    At the moment, there are over 27,000 trained doctors taking part in MSF projects and tasks. This year, more than 2300 international doctors will join {#blank#}5{#/blank#} (they) to provide medical help around the world. All kinds of doctors can volunteer for MSF. They need to be {#blank#}6{#/blank#} (prepare) to go almost anywhere and, of course, they should expect difficult conditions. When MSF accepts a doctor for a task, he has to go for {#blank#}7{#/blank#} least six months.

    When {#blank#}8{#/blank#} (ask) why he left a comfortable life and a good salary to join MSF, Chris said, “The experience I gain is a great help in my career. More {#blank#}9{#/blank#} (important), it is great to know at the end of each task that I have made a real {#blank#}10{#/blank#} (different) to people's lives.”
