You have three {#blank#}3{#/blank#} of skin which act as a barrier {#blank#}4{#/blank#} disease, poisons and the sun's harmful rays. The {#blank#}5{#/blank#} of your skin are also very {#blank#}6{#/blank#}: it keeps you warm or cool; it prevents your body from {#blank#}7{#/blank#} too much water; it is where you feel cold, heat or pain it gives you your sense of {#blank#}8{#/blank#}.

The parts of town in which they had to live {#blank#}3{#/blank#} (decide) by white people. They lived in the {#blank#}4{#/blank#}(poor) areas in the country and could not get jobs they wanted. Nelson Mandela, a modern hero, called black people {#blank#}5{#/blank#} fight against white people to make black and white people equal. He said “We were put in a position {#blank#}6{#/blank#}we had either to accept we were less important,{#blank#}7{#/blank#} fight the Government. We chose to attack the law. We first broke the law{#blank#}8{#/blank#}a way which was {#blank#}9{#/blank#}(peace); when this was not allowed…only then {#blank#}10{#/blank#}we decide to answer violence with violence.”

    Texting while crossing the street will soon{#blank#}1{#/blank#}(ban)in Honolulu, Hawaii. From October {#blank#}2{#/blank#}, you could be fined if you step into a Honolulu street while looking at your phone. Honolulu is the first major U.

Many local residents welcome the shared bikes{#blank#}6{#/blank#} the flexibility and freedom they offer. They pick up the bikes and then ride and drop{#blank#}7{#/blank#} off anywhere they like, locking the back wheel, with no need to find a fixed place.

    Analysis in China say there are three factors{#blank#}8{#/blank#} contribute to the sudden increase of bikes: a lot of cash looking for a home, a good idea and government support. “As the city's population grew, traffic jams got{#blank#}9{#/blank#} (bad).” Cai, the Ofo spokeswoman, said, “Shared bikes could solve the 'last mile' problem in{#blank#}10{#/blank#} environmentally friendly way.”
