B. A small spring in the centre causes the toy inside to bounce out with a twisting movement. The spring coils back down easily enough so that the toy can fit back into the box.

B、中間的小彈簧會使里面的玩具以扭曲得動作。彈簧很容易收縮，玩具就能收回到盒子里。

C. The water passes through the pipe, and, as it travels along, it carries the weeds with it.

C、水在流經(jīng)水管時會帶走野草。

D. The water in the pool was becoming quite polluted so a pump was used to pump the water out of the pool and force it through a filter.

D、池里的水被污染得很嚴重了，所以人們用一個泵將水從池中泵出，并使其流經(jīng)一個過濾器。

E. There is a very fine grille at different points along the pipe. These filter out any large rocks or stones. So the water is very finely strained by the time it reaches the dam.

E、在管子的不同長度處有非常精致的格欄。這些格欄能過濾掉大塊的石塊。所以當水最后到達水壩時，已經(jīng)過濾得很仔細了。

F. There is a wheel on the side, which is attached to a small motor that turns the wheel. As it spins, a long chain passes around the outside of it.

F、在邊上有個輪子，連著一個驅(qū)動輪子的小馬達。當輪子旋轉(zhuǎn)起來時，長長的鏈條繞著其外部旋轉(zhuǎn)。
