Elite (0) ...competitors..... like the Jamaican Usain Bolt have regularly been clocked running at nearly 45 kilometres per hours. Such speed would have seemed (1) ...unbelievable... not so long ago. Scientists now suggest that humans can move (2) .....even faster.... faster than even that, perhaps as fast as 65 kilometres  per hour

For years, it was assumed that simple muscle power determined human speed, but recent research suggest otherwise. The most important (3) ....limiting.... factor appears to be how quickly the muscles can contract and thus (4) ....reduce.... the time a runner's foot is in contact with the ground

Is our athletic ability inherited ? Researcher Alun Williams has (5) .....identified....... twenty - three inherited factors that influence sporting performance, such as the (6) ...efficient.... use of oxygen, and strength. As world population rises, predicts Williams, the (7) ....likelihood ..... of there being someone with the right genes for these twenty - three (24) ...characteristics .... will increase noticeably and thus faster runners are likely to emerge in future

In some place, you ...stand......(1) in a line and get a humburger or a hot dog in a paper box; ... in........(2) others you can pick up a tray of fish, chicken, pizza ....or......(3) even Mexican and Chiness food; and in some fast food places you can even .....park.......(4). your car up to a window and place your order. A ...few........(5) minutes later a worker passes you your food ......through.........(6) the window and you can drive away and eat .....it.....(7).in your car.
In New York, Paris, Tokyo, Singapore and thousands of .....big......(8) cities around the world, new fast food restaurants....often........(9) every day. But why do people ....prefer......(10) fast food restaurants to more comfortable restaurants where they can sit quietly at a table and watch the world go by?
