[单项选择]CYCLES MOVE WITH THE TIMES
Times have been hard for the UK cycle industry. Poor weather and competition from abroad have had a serious effect on sales. Manufacturers have had to cut back and last month more than 40 job losses were announced at Cycle World, one of the country’s main bicycle factories in Leicester. But the company says it is fighting to win back customers, using such strategies as improved after-sales and bikes built to specific customer requirements.
Two years ago, Cycle World sold off its bike-making machinery in an effort to cut costs and save money. The company’s Leicester factory is now only an assembly plant as most of the parts are imported.
The company produces half a million bikes a year across the full Cycle World range, with nearly all of these being sold in the UK. Production is largely done by hand. Workers use the batch production method - everyone making up to 600 bikes of a particular model at any one time.

[单项选择]
The first true piece of sports equipment that man invented was the ball. In ancient Egypt, as everywhere, pitching(投掷) stones was a favorite children’s game. But a badly thrown rock could hurt a child. Looking for something less dangerous to throw, the Egyptians made what were probably the first balls.
At first, balls were made of grass or leaves held together by vines (藤). Later they were made of pieces of animal skin sewed together and stuffed (塞满) with feathers or hay.
Even though the Egyptians were warlike, they found time for peaceful games. Before long they had developed a number of ball games, each with its own set of rules. Perhaps they played ball more for instruction than for fun. Ball playing was thought of mainly as a way to teach ’young men the speed and skill they would need for war.
The first balls were probably made of()
A. animal skins stuffed with rocks
B. twists of hay
C. hides(兽皮) stuffed with hat or feathers
D. grass and leaves tied with vines
